Because young children provide incomplete accounts of the past and tend to acquiesce to leadingquestions, procedures are needed to help them describe past events fully, without contaminatingmemory. This study tests the efficacy of "narrative elaboration," an innovative procedure designedto expand children's spontaneous reports of past events, reducing the need for leading questions.One hundred thirty-two children from 2 age groups (7-8 years and 10-11 years) were assignedrandomly to 1 of 3 preparation conditions: (a) narrative elaboration intervention, (b) instruction-based intervention, and (c) control group.

Ultimately, this could mean fewer children re-turned to dangerous situations and fewer innocent adults falselyaccused of abuse. The procedure of narrative elaboration wasdeveloped to address this need—to assist children's retelling ofevents without compromising accuracy. The present study testsits efficacy in the laboratory.

Relevant Research

Narrative elaboration is designed to help children overcomedevelopmental limitations in memory and communication welldocumented in the experimental literature. In laboratory stud-ies, children's responses to open-ended requests, such as, "Whathappened?" (free recall) are more accurate than their responsesto specific questions (e.g., Goodman & Reed, 1986). Unfortu-nately, these relatively spontaneous descriptions (e.g., "Weplayed") are notably incomplete (Nelson, 1986). Hence, spon-taneous event recall, despite its accuracy, is often insufficientfor evaluating suspicions of abuse. Children provide additionalinformation in response to follow-up questions, much of whichis accurate; but questions, if misleading, distort children'sreports.

Older children and adults use more complex and successfulretrieval strategies than younger children to retrieve informa-tion independently (e.g., Ornstein, Naus, & Liberty, 1975).Younger children are dependent on external cues (in the formof adult questions) to search their memories in an efficient, sys-tematic, and organized fashion (Fivush, 1993; Pillemer &White, 1989). Young children's ability to narrate autobio-graphical events is impeded by limited event knowledge(understanding of the causal and temporal relations amongevents) and impoverished generic memory structures, often re-ferred to as scripts, that guide attention, retrieval, and retention

processes. Eventually, children develop self-cuing strategies asthey learn which questions to ask themselves in order to includethe "who," "when," "what," and "where" independently.

Not only do children possess less developed scripts and strat-egies to guide independent retrieval, they also possess less devel-oped communication skills to estimate the listener's priorknowledge on the topic and to orient the listener to time, place,and perspective (e.g., Dickson, 1981). They have difficulty an-ticipating the listener's needs to provide missing context cuesand to elaborate on the unfamiliar spontaneously. Moreover,children have limited knowledge of the legal system itself (e.g.,Saywitz, 1989). This could hamper their ability to judge foren-sic relevance, to perceive the purpose of the interview, or to inferthe interviewer's expectations. These limitations leave childrenunaware of the kinds of information and level of detail expectedof a witness in a forensic interview (Saywitz, Nathanson, Sny-der, & Lamphear, 1993).

Narrative elaboration was developed with these childhoodlimitations in mind. It is both a procedure for preparing chil-dren to be questioned and a format for interviewing them (seeAppendix). To address insufficiencies in strategies and scripts,we teach children a strategy for retrieving details by organizingthe elements of an event into categories thought to be psycho-logically salient constructs that guide event recall (Mandler &Johnson, 1977). The categories (participants, setting, actions,conversation/affective states, consequences) are derived fromscript theories of children's event knowledge (Stein & Glenn,1978). Each category is represented by a line drawing on a card(see Figure 1). These external cues remind children to reportas much detail as possible from each category. Children practiceusing the cards on mock recall tasks. Later, when questionedabout the event under investigation, children are initially askedfor an uninterrupted description ("What happened?"). Af-terward, each card is presented and the child is asked, "Does

Elements of Narrative Elaboration

Narrative elaboration incorporates six experimental proce-dures that have enhanced the memory performance of school-age children in the laboratory: (a) memory strategy instruction,(b) organizational guidance according to category cues, (c) ex-ternal memory aids (e.g., pictorial cues), (d) rationale for strat-egy usefulness, (e) practice with feedback, and ( f ) reminders touse new strategies on subsequent trials.

Strategy instruction. Studies have shown that young chil-dren can be taught to use retrieval strategies to improve recall,although they would not use such strategies spontaneously(Flavell, 1970; Paris, Newman, & McVey, 1982). Specifically,strategies that enhance children's knowledge of scripts for sto-ries, often referred to as story grammars, aid children's com-prehension and production of stories (Singer & Donlan, 1982).Children show better recall, comprehension, and retelling ofwell-formed stories in comparison with stories that violate ex-pected structures and script knowledge (Stein & Nezworski,1978). Children with more story grammar knowledge recallmore information overall and make fewer errors on story recallthan children with less knowledge (Fitzgerald & Spiegel, 1983;Pearson & Camperell, 1981). The present study tests whethersuch categories aid recall of live events.

Visual cues. In general, studies find that verbal reports un-derestimate children's knowledge. Supplemental visual cues al-low children to demonstrate additional knowledge (Nelson,1986). To guide children's retrieval efforts, we developed picto-rial depictions of the Stein and Glenn (1978) story grammarcategories. Kobasiwaga (1974, 1977) demonstrated that cate-gory cues depicted in pictorial form (picture of zoo) aid chil-dren's recall of categorizable lists (animals). In addition, pic-tures representing story grammar categories have been used tohelp children systematically list all aspects of a story relatedto each category (Westby, 1985), but children still need to bereminded to use each category independently (Fitzgerald &Spiegel, 1983).

Strategy utility, practice, feedback, and reminders. Narra-tive elaboration provides children with a rationale for strategyusefulness, practice with feedback, and reminders to use thenewly learned technique on subsequent opportunities. In-creased awareness of the value of the strategy for improving per-formance has been related to better recall (e.g., Lodico, Gha-tala, Levin, Pressley, & Bell, 1983; Ringel & Springer, 1980) andto selecting more effective retrieval strategies (Ghatala, Levin,Pressley, & Lodico, 1985; Lodico et al., 1983; Pressley, Ross,Levin, & Ghatala, 1984). Further, there is evidence that knowl-edge concerning the value of the strategy helps maintain strat-egy use after initial training and extends to its use to new tasks(Lodico etal., 1983; Pressley etal., 1988).

In addition, studies have shown that children benefit frompractice with new strategies, when they are given explicit feed-back on their progress or are prompted to use the strategy justbefore the memory test (Pressley et al., 1984). Even older chil-dren up to 12 years of age have benefited (Pressley & Dennis-Rounds, 1980). To maximize completeness and minimize gen-

INTERVIEWING CHILDREN 1349

eralization problems, children practice using the visual cues onmock recall tasks with feedback; they receive reminders imme-diately before questioning (Pressley, Forrest-Pressley, & Elliott-Faust, 1988).

Design

The present study examined children's memory for a stagedclassroom event involving an argument among adults that im-plicated the children. Within each of two age groups (7-8 and10-11), children were assigned randomly to one of the threetreatment conditions: (a) narrative elaboration intervention,(b) instruction-based intervention, and (c) control group, asdescribed later. Completeness, accuracy, and quality of memoryfor the staged event were compared across treatment conditionsand age groups.

Two age groups and three treatment conditions were neces-sary to assess whether instructions alone improve recall forolder children who use many retrieval strategies spontaneouslyor whether the entire intervention is necessary for both agegroups to benefit. Past studies have suggested that children's re-call can benefit from instructions (Wellman, Fabricus, & Wan,1987; Wellman, Ritter, & Flavell, 1975; Yussen, 1974). The agerange sampled was chosen to avoid ceiling and floor effects. Lab-oratory studies of recall for word lists and pictures suggest that7- to 8-year-old children begin to show a level of metacognitiveawareness sufficient to use retrieval strategies with some effi-ciency and flexibility. Still, complex heuristics resulting in ex-haustive memory searches are rarely seen until the end of gradeschool and may not be mastered until adolescence (Salatas &Flavell, 1976). Hence, children in the sampled age range wouldhave sufficient baseline skills to learn the new strategies and stillhave room to demonstrate improvement.

Hypotheses

The present study tests whether narrative elaboration train-ing is associated with a greater number of correct propositionsreported in spontaneous recall' in comparison to reports fromchildren who did not receive this training. We predicted thatthis would be accomplished without generating unintended er-rors and without adversely influencing children's responses tosubsequent follow-up questions. An interaction between ageand treatment condition was predicted because instructionsalone might be sufficient for older children to demonstrate bet-ter recall than the control group, whereas younger childrenmight require the complete intervention package to show im-provement over the control group's performance.

With regard to the quality of recall, two additional predic-tions were made. Taking into account that young children's nar-ratives are primarily descriptions of actions (Fivush & Ham-mond, 1990), we predicted that the intervention would sensi-tize children to report information from other categories aswell, if such information had been encoded. On the basis of paststudies suggesting that children's narratives often lack detailand that children are more accurate in response to questionsabout central events than about peripheral details (Goodman,Rudy, Bottoms, & Aman, 1990; Saywitz, Goodman, Nicholas,& Moan, 1991), we predicted that the intervention would in-

crease the number of peripheral details reported in comparisonto recall for main ideas.

Method

Participants

One hundred thirty-two children from middle-class families insouthern California participated. Two age groups comprised this sam-ple: 7- to 8-year-olds (n = 65; M = 90.60 months, SD = 4.46 months)and 10- to 11-year-olds (n = 67; M = 129.95 months, SD = 6.85months). There were 67 boys and 65 girls. Written informed consentwas obtained from a parent or legal guardian. Children's assent was alsoobtained verbally and in writing. Ethnicity data were available for 60%of the sample. Missing data were randomly distributed across levels oftreatment condition, age, and gender. The remaining sample was 81%Caucasian, 6% Hispanic. 5% Asian, 3% Black, and 5% other.

Staged Event

A classroom event was designed to encompass many of the elementsof events about which children may testify or be interviewed. It wascomplex, with four distinct episodes, rich in detail and action, whichwould later demand recall of a high caliber. It involved the childrenemotionally during a staged disruption, providing an emotionallycharged distraction that could confuse the children later during de-mands on them to reconstruct what happened. To the extent that theexercise simulated demands typically made on child witnesses, it is eco-logically valid. It is bound to fall short because of the necessity to sparechildren from bodily or psychological harm.

Two professional actors were" hired to play student teachers whotaught a history lesson, a craft activity, a song, and a folk dance aboutMexico for 30 min. Midway through the craft activity, a confederateteacher entered, accusing the teacher of taking his craft materials with-out asking. She had already distributed the "borrowed" markers to thechildren who were automatically implicated in the disagreement and itsresolution. Children's reactions demonstrated their emotional involve-ment. Some hid the materials under their desks while the adults argued.When the disagreement was resolved by modeling appropriate prob-lem-solving skills, resulting in a plan to share the markers, some chil-dren clapped.

Procedure

The children's teacher introduced the student teachers to the class,explaining that the lesson would be videotaped. This was done to ensurethat their memories would be compared with what actually happened,not what was supposed to have happened. Children were told that thepurpose was to make a videotape to be used to teach other children inother schools. To further enhance ecological validity, children were nottold in advance that their memory would be tested.

Two weeks after the classroom event, research assistants returned fora 45-min individual session with each child in a quiet place on theirschool campus. Children from each age group were randomly assignedto one of three research assistants. First, 5 min were spent in rapportdevelopment. To ensure that all participants possessed the baseline ver-bal and narrative skills necessary to participate, research assistants nextadministered the Peabody Picture Vocabulary Test—Revised (PPVT-R) and tested free recall for a Stein and Glenn (1978) story, Judy'sBirthday. The individual session continued with the training (or

control) portion of the session, depending on condition assignment,which lasted approximately 30 min for all children.

Two days later, children met individually with the same research as-sistant. After a brief review of the previous session, each child was inter-viewed about the classroom event. Children were told that the in-terviewer was not present and had no knowledge of what had occurredto control children's perceptions of the interviewer's knowledge and ex-pectations. At the conclusion of the interview, children were comple-mented for their effort, thanked for their participation, and returned toclass. After the conclusion of the data collection phase, a research assis-tant returned to inform the class that one purpose of the experimentwas to study children's memory skills.

Treatment Preparation Sessions

Narrative elaboration intervention (Group A). This interventionconsisted of six components—(a) Rationale for strategy utility: An ex-planation of the value of using new ways to remember better; (b) in-structions to be complete and accurate: "When you tell what happenedto you, tell as much as you can about what really happened, even thelittle things, without guessing or making anything up"; (c) Strategy:Introduction of a strategy for organizing narratives into five categoriesand reporting a specified level of detail from each category; (d) VisualCues: Introduction of generic visual cues to remind self of each cate-gory; (e) Practice, Modeling, and Feedback: Practice using the newstrategy and the visual cues on mock recall tasks with feedback on ac-curacy and with modeling of more detailed and relevant responses; and( f ) Reinstruction: Review of Items b through d.

To demonstrate strategy utility, children began with a procedure de-vised by Pressley and his colleagues to illustrate that there are better andworse ways to accomplish a drawing task (e.g., use a stencil) with ananalogy to the way that strategies improve memory (Pressley et al.,1984). Next children were provided with accuracy and completenessinstructions as presented in Item b. Then, they were taught that theycan improve their recall by organizing the event information into fiveparts (categories) using reminder cards. Each part (category) was rep-resented by a simple line drawing on a separate card referred to as "re-minder signs."2 The drawings were generic in character to be useful indifferent situations and to avoid bias. Extensive pilot testing was con-ducted to revise the drawings so that none were used in a literal fashion,resulting in slight differences in the pictures for the two age groups.3

Each card was introduced in a similar manner to the participant cardin the following example. Children were told the subsequent statements.

This is the people card. When you talk about things that have hap-pened, you will need to remember the people who were there(identity), what they looked like (physical appearance), and howthe were dressed (clothing). You can use this sign to help youremember.

Then, during three mock recall tasks, children practiced each cardindividually and then the entire set. Practice tasks involved recall ofone autobiographical event ("What have we done together so far in oursession?") and two brief videotaped vignettes provided by the Chil-dren's Television Workshop (CTW). Each time, the children were askedto tell what happened, then the card was presented and the childrenasked if there was anything else the card reminded them to tell. Theresearcher elaborated on the child's response, demonstrating additionalkinds of information that could be reported if remembered (e.g.. hair,skin, eye color, body size, age, glasses). To discourage task-inefficientresponses and protect accuracy, children were cautioned repeatedly notto guess or push themselves to recall details about which they wereunsure.

In the beginning of the second session, before the memory test, chil-

dren were reminded of the instructions to be complete and accurate andto use the reminder signs.

Instruction-based intervention (Group B). These children partici-pated in the same drawing task and received the same rationale for usingstrategies to remember events "better." They received the same instruc-tions to be complete and accurate and were told to practice by recallingthe same autobiographical event used with Group A. They watched andrecalled the same videos as Group A but without feedback, modeling,or visual cues. Specifically, they were not taught to organize their narra-tives into story grammar categories and were not exposed to the re-minder signs. They did, however, spend similar amounts of time withthe same research assistants involved in similar activities and with sim-ilar materials as Group A. In the beginning of the second session, theyreviewed the instructions.

Control session (Group C). As with the other two groups, the con-trol group participated in the same drawing task but was given no ratio-nale for strategy usage. They watched two videos provided by CTW, asdid the other two groups, and practiced recalling them. These two vid-eos, one on various animal species and behaviors, another on assem-bling a go-cart, were chosen because they contained elements that wereeasily categorized. Children answered questions that required categori-cal knowledge. Thus, all groups engaged in tasks of similar interest,challenge, and skill. These children spent the same amount of time withthe same researchers, involved in similar activities and materials as theother two groups. At the beginning of the second session, they reviewedwhat they learned in the first session.

InterviewChildren were interviewed individually for approximately 15 min in a

quiet room on the school campus, a familiar environment. All childrenreceived the same interview instructions and questions.4 The interviewinvolved three tasks: (a) free recall, in which children were asked to givea narrative account of what had happened; (b) cued recall, in whichchildren were given the opportunity to elaborate on their narrative usingthe visual cues as each card was presented individually to all partici-pants; and (c) probed recall, in which children were asked a series of28 short-answer questions about the classroom event, resembling thoseasked in forensic evaluations (e.g.. Who was there? What did they looklike? What was his name?).5 Comparable numbers of questions weredevoted to main ideas, intermediate ideas, and peripheral details.

2 For the younger age group, the introduction of the cards was pre-ceded by introduction of a stop sign. All children demonstrated an un-derstanding of the meaning of a sign (i.e., it tells you what to do—stop).An analogy was drawn to the reminder signs that tell you how to re-member better. Drawings used with the younger age group were encom-passed by an octagon to facilitate the connection.

3 A preliminary study was conducted with 72 six- and nine-year-oldsto refine the methodology before the present study (Saywitz & Lam-phear, 1989).

4 "Now you will have a chance to tell me about something that reallyhappened to you and your class. Do you remember a couple of weeksago when some people came into your classroom to make a video? Be-cause I was not there to see it, I want you to tell me what you rememberabout it. You can use these cards if you like." Children were promptedonce with "anything else?" at the conclusion of free recall unless theyindicated they were done (e.g., "that's all."). After the children com-pleted their narratives, the interviewer presented each card individuallyto the child and asked, "Does this card remind you to tell anythingelse?" After this cued recall task, children were told, "Now, I am goingto ask you some questions about what happened that day in the class-room. Don't make up anything. Just tell me as much as you canremember."

5 The questions are available on request from Karen J. Saywitz.

Coding

We developed a checklist for coding children's free recall data by con-ducting a prepositional analysis of the script of the staged event. Propo-sitional analysis has become the method of choice for analyzing the ele-ments of meaning present in sentences and discourse (Kintsch & VanDijk, 1978). It is considered a sensitive and robust indicator of compre-hension and memory for detailed information. It is well established thatthe number of propositions in any stretch of discourse is correlatedmore highly with comprehension and memory for the event retold thanthe number of words or sentences (Snyder & Downey, 1991). Using thismethod, Lynn Snyder created an extensive list of propositions consti-tuting the staged event. She achieved an intercoder agreement of 93%with a second coder trained in this system who undertook the same task.Redundant propositions were eliminated, resulting in a checklist of 450items.

The correspondence between the level of representation generated bya prepositional analysis and human information processing has beenwell documented in the literature (Snyder & Downey, 1991). To en-hance ecological validity, we tested the correspondence between thepropositions on our checklist and the propositions recalled by individu-als after watching a videotape of the event. This verification was exam-ined by having 14 graduate students in the Department of Communi-cative Disorders at California State University, Long Beach, view theevent being staged with a class of children. The students were then askedto take 20 min to write what they had seen. The mean agreement be-tween the higher level propositions identified by the graduate studentsand the higher level propositions generated by the Lynn Snyder analysiswas 94%.

For both free and cued recall, memory of each item on the checklistwas coded as correct, incorrect, or omitted from child's report. If a childreported a statement that was not captured by the checklist but wasverifiable, it was scored as well. Un verifiable information was rare. Cuedrecall scores were composed of new information not reported pre-viously in free recall. Answers to probed recall questions were coded ascorrect, incorrect, or don't know. Two raters who were not informed ofcell assignment and the hypotheses of the study each coded 25% of thechildren's protocols, attaining 99% interrater reliability. One of the rat-ers coded the remaining protocols.

Results

The data were analyzed to address three primary questions.First, does narrative elaboration training increase the numberof correct propositions reported in spontaneous recall by 7- to8-year-old and by 10- to 11-year-old children? Second, if so,does improvement in free recall come at the expense of in-creased errors, either in free recall or on nontarget follow-upquestions? Third, what is the effect of narrative elaboration in-tervention on quality of recall; specifically, is the additional in-formation generated forensically relevant and sufficientlydetailed?

Preliminary Analyses

To demonstrate that memory differences between treatmentgroups were a function of the intervention and not a priorigroup differences on related cognitive abilities, we conductedpreliminary analyses to demonstrate that groups were compa-rable on verbal skill (as measured by scores on the PPVT-R),and narrative skill (as measured by recall scores for a Stein andGlenn story) before intervention. Two 3 X 2 X 2 (Treatment

Condition X Age X Gender) analyses of variance (ANOVAs)were conducted on PPVT-R scores and story recall scores.There were no significant main effects or interactions involvingtreatment condition (all Fs < 1.84). In addition, there were nosignificant differences in memory performance as a function oftester identity. One-way ANOVAs were conducted across thethree research assistants on number correct and number incor-rect on free recall, cued recall, and probed recall scores (all Fs< 1.65). Thus, tester identity was not entered into the mainanalyses discussed later. There were no differences betweentreatment groups in the distribution of ethnicity. From thesepreliminary analyses, we concluded that there was a high likeli-hood that if memory differences between treatment groupsemerged they would be a function of our intervention.

Interviewers followed a standardized interview protocol. Pre-liminary analyses demonstrated that treatment groups did notdiffer in the number of times children were prompted duringfree recall, in number of reminder cards presented, or in num-ber of probed questions asked.

Does Narrative Elaboration Intervention FacilitateRecall?

We hypothesized that the experimental intervention wouldbe associated with greater spontaneous recall of correct infor-mation for children all ages. Secondarily, we predicted an in-teraction between age and treatment condition. We also exam-ined gender effects because they emerged in a previous studyusing a similar paradigm (Saywitz & Moan-Hardie, 1994). Toexamine the effects of intervention, age, and gender on memory,3 x 2 x 2 (Treatment Condition X Age X Gender) multivariateanalyses of variance (MANOVAs) were conducted with threedependent measures, free recall, cued recall, and probed recall,unless otherwise specified.

When the number correct on free, cued, and probed recallwas entered into the MANOVA, there were significant maineffects of treatment condition, F(6, 236) = 3.87, p < .001; age,F(3, 118) = 22.26, p < .0001; and gender, F( 3, 118) = 3.72, p< .01. Wilks's lambda was used to estimate F values. Interac-tions were not significant (all Fs < 1.34).

Free recall. Univariate tests on free recall scores revealedsignificant main effects of treatment condition, F(2, 120) =5.89, p < .005; and age, F( 1, 120) = 30.45, p < .0001. Table 1presents the means and standard deviations for the number ofpropositions reported in free, cued, and probed recall tasks bytreatment condition and age group. Post hoc Bonferroni testsindicated that the narrative elaboration group (M, = 16.23, SD,= 8.33 )6, reported more correct propositions in free recall thaneither of the other two treatment groups who did not differ fromeach other (Afb = 10.96, SDb = 7.27; and A/c = 12.29, SDC =8.72). Older children (M = 16.64, SD = 9.10) reported morecorrect propositions in free recall than younger children (M =9.72, SD = 5.90). Gender effects and interactions were not sig-nificant (all Fs < 2.06).

Cued recall. Univariate tests on cued correct recall scoresrevealed a significant effect of training, F(2, 120) = 6.12, p <.003. Bonferroni tests indicated that the narrative elaborationgroup reported significantly more correct propositions in re-sponse to the visual cues (M, = 5.33, SDa = 7.30) than either ofthe other two groups who did not differ from each other (A/b =1.45, SDb = 2.87; Afc = 1.77,5Z?C = 2.84; only new informationnot reported previously in free recall was counted). Age, gender,and interaction effects were not significant (all Fs < 2.28).

Probed recall. Univariate tests on probed correct recallscores failed to demonstrate an effect of training. Analyses re-vealed significant effects of age, F( 1, 120) = 28.95, p < .0001,with older children (M = 18.34, SD = 2.61) responding to morequestions correctly than younger children (M = 15.98, SD =2.80). There was also a significant effect of gender, F( 1, 120) =9.03, p < .003, with girls (M = 17.89, SD = 3.00) respondingto more questions correctly than boys (M = 16.49,5D = 2.75),although the absolute difference was small. There were no sig-nificant interactions (all Fs < 1.20).

In summary, as predicted, children with narrative elabora-tion training provided more units of correct information inspontaneous recall, M = 21.76, than children who received onlyinstructions to be accurate and complete, M = 12.41, or nointervention at all, M = 14.06. This was accomplished withoutreducing correct responses to follow-up questions. The data didnot support the hypothesis that instructions to be accurate andcomplete aid recall in this paradigm.

Does Narrative Elaboration Generate Unintended Error?

To assess the full effects of the intervention and its potentialutility in the clinical and forensic setting, we entered the num-ber of errors on free, cued, and probed recall into theMANOVA. Significant main effects of age, F(3, 118) = 11.82,p < .0001; and gender, F(3, 118) = 4.02, p < .01, emerged.There were no significant treatment effects or interactions (allFs < 1.41). Thus, there was no evidence that the interventioncaused unintended errors in recall (see Table 1).

Univariate tests on free recall error scores showed no signifi-cant effects or interactions (all Fs < 1.26). Univariate tests oncued recall error scores revealed a significant main effect of age,F( 1, 120) = 5.14, p < .05, with younger children making moreerrors, M = .25, SD = .66, than older children, M = .03, SD= .17. Univariate tests on probed recall error scores revealedsignificant main effects of age, F( 1, 120) = 26.33, p < .0001;and gender, F( 1, 120) = 12.18, p < .001. Younger children re-sponded to more questions incorrectly (M = 6.14, SD = 2.60)than older children (M = 3.90, SD = 2.55). Boys (M = 5.69;SD = 2.94) responded to more questions incorrectly in probedrecall than girls (M = 4.29, SD = 2.46). Again, the absolutedifference was small.

In summary, the narrative elaboration method increasedcompleteness of children's spontaneous narrative reports with-out adverse consequences. The intervention affected only thataspect of the children's memory performance targeted by theexperimental procedure. It had no measurable adverse effects

INTERVIEWING CHILDREN 1353

on follow-up questions in the probed recall task. Children in thenarrative elaboration group demonstrated 53% improvement incompleteness of accurate spontaneous narrative reports overthe control group.

Age Effects

Traditional age-related differences in memory performancewere reduced markedly by the narrative elaboration method.Younger children who received intervention performed compa-rably with older children in the control group. When the num-ber of correct propositions reported in free recall was enteredinto Tukey pairwise comparisons of cell means, the differencebetween younger children in the narrative elaboration condi-tion (M = 13) and older children in the control group (M = 16)was not significant at thep < .05 level. In fact, when the numbercorrect in spontaneous recall (i.e., sum of correct free recall andcorrect new propositions in cued recall) was entered into thepairwise comparisons, age-related differences were eliminatedaltogether. The average total number of correct propositions re-called by younger children in the narrative elaboration group(M = 19) exceeded that of the older children in the controlgroup (M = 17.50), although this difference was not statisti-cally significant.

How Does Narrative Elaboration Affect Quality ofRecall?

Categorical analyses. Given that children's narratives pri-marily comprise statements about actions, we predicted thatthere would be little room for improvement in the recall of ac-tions but a greater opportunity for improved reporting in othercategories, if such information had been encoded. We identifiedeach of the 450 items on the checklist with one of the five storygrammar categories. The number of correctly reported propo-sitions from each category was entered into a 3 (Training) X2 (Age) X 2 (Gender) MANOVA. There were main effects oftreatment condition, F( 10,232) = 3.17, p < .001; and age, F( 5,116) = 7.01, .p < .0001. Gender effects and interactions were notsignificant (all Fs < 1.55). Univariate tests showed significanteffects of treatment condition on three categories: participants,F(2, 120) = 5.68,.p < .005; setting, F(2, 120) = 5.43,p < .005;and affective states/conversations, F( 1, 120) = 4.88. p < .01.Figure 2 presents the mean number of propositions recalled cor-rectly from each category in free and cued recall by treatmentcondition.

Bonferroni post hoc tests suggested that the narrative elabo-ration group recalled significantly more information about par-ticipants than the control group (A/a = 1.06, SD = 1.98; A/c =.34, SD = .64). The narrative elaboration group recalled sig-nificantly more propositions about the setting than the instruc-tions group (M, = 2.04, SD = 2.43; Mb = .78, SD = 1.16).Differences between the narrative elaboration group and con-trol group (A/c = 1.46, SD = 1.92) did not reach significance;however, the means were in the predicted direction. The narra-tive elaboration group also recalled more propositions aboutaffective states and conversations than the instructions group(Afa = 5.08, SD = 3.78; Mb = 2.94, SD = 3.07). Again, differ-ences between the narrative elaboration group and the control

group (A/,. = 3.50, SD = 3.39) did not reach significance; how-ever, means were in the predicted direction. Taken as a whole,this pattern favors narrative elaboration over the other trainingconditions examined on these three types of information. Datawere sparse in some cells, especially for children in the instruc-tion and control groups who frequently failed to report anypropositions in one or more categories.

The MANOVA also produced a significant effect of age onrecall of categorical information. Univariate tests showed sig-nificant age effects on each of the schema-based categories: par-ticipants, F(\, 120) = 13.25, p < .001; setting, F(\, 120) =10.55, p < .001; actions, F(\, 120) = 21.13, p < .0001,conversations/affect states, F( 1, 120) = 12.48, p < .001; andconsequences, F( 1, 120) = 8.54, p < .001. Effects of gender andinteractions were not significant (all Fs < 1.55).

Taken as a whole, these data suggest a consistent pattern. Thenarrative elaboration procedure tends to be associated with im-provements in recall of information about the participants, set-ting, and affective states/conversations. The procedure does notappear to improve reports of actions or consequences. Failureto improve the number of actions reported was not due to aceiling effect. The checklist contained 103 potentially memora-ble actions. The maximum number of actions recalled by achild in free recall was 20, M = 6.44. Of the categories studied,the action category was the one most readily reported by chil-dren with minimal cuing. Because the consequence cue waspresented last, fatigue could be responsible for poor recall ofthis type of information.

Hierarchical analyses. We also hypothesized that the inter-vention would increase the number of peripheral details re-called without necessarily affecting the recall of main ideas.Hence, each of the 450 items on the checklist was categorizedas either a main idea, intermediate idea, or peripheral detail, onthe basis of the propositional analysis of the classroom event.The number of main ideas, intermediate ideas, and peripheraldetails recalled correctly in both free and cued recall was en-tered into a 3 (Training) X 2 (Age) X 2 (Gender) MANOVA.There were significant effects of treatment condition, F(6,236)= 5.36,p<.0001; and age, F(3,118) = 12.14,p<.0001.Therewere no significant effects of gender and no significant interac-tions (all Fs< 2.40).

Univariate tests on the number of main ideas, intermediateideas, and details reported correctly in spontaneous recall re-vealed main effects of treatment condition and age for each level(main ideas: treatment condition, F( 2, 120) = 9.81, p < .0001;and age, F(l, 120) = 36.91, p < .0001; intermediate ideas:treatment condition, F(2, 120) = 4.73,p < .01; and age, F(\,120) = 7.50, p < .01; details: treatment condition, F(2, 120) =12.92, p < .0001; and age, F( 1, 120) = 5.78,;? < .05). At eachlevel, Bonferroni post hoc tests revealed that the narrative elab-oration group reported significantly more correct propositionsthan either of the other two groups who did not significantlydiffer from each other. These results failed to support our pre-diction. Memory for all three levels improved. The interventionmay have enhanced the children's ability to access the complex-ity (main ideas from the four distinct episodes) as well as therichness (peripheral details) of the event. Prior studies showingfew developmental differences in recall of main ideas typically

Discussion

Our results suggest that narrative elaboration can be a prom-ising method to help children produce more complete and de-tailed descriptions of past events without compromising accu-racy. Children who received the experimental interventiondemonstrated a 53% improvement over the control group in ac-curate spontaneous recall. Children accessed information withthis novel technique that they did not report spontaneously.This was accomplished without the use of leading questions andwithout affecting responses to follow-up questions. The extrainformation dealt with the participants (identity and physicalappearance), their emotional states, the statements made, andthe setting. The additional information these children producedwas enhanced in complexity (main ideas) and in richness(details).

More complete spontaneous reports reduce the need for lead-ing follow-up questions and the consequent risk of contamina-tion. This is most important for younger children who oftenproduce skeletal narratives, requiring follow-up questions forclarification, and who are also least able to resist suggestivequestions. In the present study, younger children in the narra-tive elaboration condition demonstrated recall comparable witholder children in the control group.

There were no measurable benefits of instructing children tobe complete and accurate, even among older children. Thisfinding highlights the need for empirical investigation of theeffectiveness of individual components of clinical interviewprocedures.

Ecological Validity

In this study, special care was taken to enhance the ecologicalvalidity of the stimuli by staging a live, emotionally compellingevent rather than using stories or pictures. The retention in-terval was weeks, not days, and the retention test consisted ofshort-answer questions modeled after actual interviews, thusdiffering from previous studies. Although the results are prom-ising, we do not know if benefits will be maintained when eventsto be recalled are traumatic, humiliating, unresolved, highlypersonal, and are experienced alone and in secret. A series ofstudies is needed to test the efficacy of this technique in the fo-rensic context—a context that often involves multiple events,interviews, and interviewers over extended periods of time. Theinterviews in this study were briefer than typical in the forensicsetting. It is possible that children would have generated moreerror if interviews were lengthier. Also, the sample was primar-ily composed of Caucasian, middle-class children, althoughpreliminary analyses of a subsequent study suggest that a mod-ified procedure can be beneficial to a population including eco-nomically disadvantaged children (Dorado, 1996).

INTERVIEWING CHILDREN 1355

Two aspects of the design itself limit our interpretation of theresults. First, the interviewers were not uninformed of condi-tion assignment. Interviewer expectancies could have influ-enced the results. However, the design of the present study issimilar to the typical interview setting in which the evaluator orattorney prepares the child for the interview and then conductsthe subsequent questioning themselves. For these situations, thedesign of the present study appears valid. Second, the visualcues were always administered in the same order. It is impossi-ble to disentangle the effects of the specific category from itsposition of presentation. Additional experiments with random-ized order of presentation, and unfamiliar interviewers areneeded to address these issues.

Application to Clinical and Forensic Settings

The clinical literature is replete with recommendations forinterviewing children. Few have been empirically tested. If fu-ture studies confirm that narrative elaboration helps childrendescribe past experiences accurately and in greater detail with-out leading questions, then worthy cases of abuse could be pros-ecuted more effectively and false allegations could be disre-garded more frequently. Obtaining detailed statements fromchildren earlier in the process could reduce the number of in-terviews children undergo. Repeated interviews are thought tocreate stress (Tedesco & Schnell, 1987), inconsistency (Fivush& Shukat, 1995), and contamination (Ceci & Bruck, 1993).If interviews followed a common format, narrative elaborationbeing but one example (preparation followed by free recall,cued recall, and finally, specific questions), then opportunitiesfor interviewer error, distortion, and inconsistency across state-ments might decline.

Laboratory tested techniques could prove useful in two otherregards. Concerns that preparation is tantamount to contami-nation undermine children's credibility. The use of techniquesdemonstrated to be free of adverse effects on memory could bol-ster children's credibility. In addition, such techniques couldfacilitate recovery from trauma (Cohen & Mannarino, 1996).Concerns over contamination often delay needed therapy. Ifused to guide recall in pretrial therapy sessions, such techniquescould promote timely clinical intervention.

Even if future studies replicate and extend these encouragingresults to situations that more closely resemble the investigativeand clinical context, the problem of generalization to the court-room is likely to remain. Children in this age range often havedifficulty transferring new skills to unfamiliar situations with-out reminders or cues. However, if prepared in advance, childwitnesses could be reminded to use the strategies right beforean additional interview or courtroom examination. Although itmay be unusual for children to use visual cues to aid retrievalin front of a jury, this should be no more problematic than theuse of other demonstrative tools, such as the drawings that arefrequently used to supplement children's limited languageskills. The genuine benefits of a relatively brief procedure dem-onstrated to enhance children's reliability without infringing onthe rights of the accused should outweigh most presumed bar-riers to implementation.

Our findings demonstrate the value of extrapolating from thelaboratories of developmental psychology to create new meth-

ods for enhancing children's eyewitness performance in theclinical and forensic venue. The value of developmentallybased, empirically tested interview guidelines in cases of sus-pected child maltreatment is clear. If adults can help childrenprovide more accurate and complete reports of past eventswithout the risk of distortion, society's efforts to discover truth,protect the rights of the accused, and promote the welfare ofchildren will be advanced.
