Abstract This paper examines text structure and patterns of cohesion in stories

written by a group of adults with a history of childhood language impairment. The

study aimed to extend our knowledge of writing difficulties in this group by building

upon a study that examined clause level phenomena (Smith-Lock, Nickels, &

Mortensen, this issue). Ten adults with a history of Language Impairment and 30

control participants were asked to write the story of Cinderella. Stories were ana-

lyzed for their generic structure and cohesion resources, both of which contribute to

the organization and coherence of a text. Results revealed that patterns of text

organization at the level of generic structure and measures of cohesion did not

distinguish the performance of writers with a history of Language Impairment from

the comparison group. A wide range of lexico-grammatical skills was evident within

the Language Impaired group, with few individuals with Language Impairment

falling outside the normal range of performance. It is suggested that generic

structure and cohesion are a relative strength in the writing of adults with Language

Impairment, within the constraints of their lexical and grammatical skills.

Introduction

The ability to produce written texts is a critical life skill in a literate society. Writing

is a complex and demanding form of communication that draws upon a number of

underlying cognitive, linguistic, and social factors. It uses information-processing

abilities such as attention, perception, memory and reasoning, language skills such

as vocabulary, syntax and text organization, as well as phonological and

orthographic skills. In addition, a writer requires an awareness of the person(s)

for whom the written material is intended, i.e., ‘‘a sense of audience’’ (Gregg, 1991).

Impairment in the ability to write, be it a developmental or acquired deficit, clearly

has far-reaching implications for an individual’s literacy, learning, and employment

opportunities, as well as expression of self and identity (Ivanic, 1998).

In studying and analysing the discourse abilities of adults with writing

impairment, a number of different theoretical orientations are apparent. Discourse

production has been described in terms of contextual influence on the function of a

text (Halliday & Hasan, 1985), cognitive organization and process (e.g., Stein &

Glenn, 1979; van Dijk, 1981), linguistic structure and textual coherence (Bamberg,

1987; Halliday & Hasan, 1976), and sentence-level complexity (Bishop & Clarkson,

2003; Gillam & Johnston, 1992; Scott & Windsor, 2000). These perspectives reflect

the complex of social, cognitive, and linguistic factors that comprise written

discourse and provide different perspectives from which to examine discourse

production, written or spoken.

Written discourse has been found to be a sensitive indicator of residual or

persistent language impairment in adults. Investigations of adults and adolescents

with traumatic brain injury, for example, have revealed problems with text

organization and information management in written texts, while their lexicogram-

matical abilities remain relatively intact (Mortensen, 2004a; Wilson & Proctor,

2002). Adults with aphasia, on the other hand, have demonstrated competent

narrative text structure in spite of difficulties at the clause level (Freedman-Stern,

Ulatowska, Baker, & DeLacoste, 1984; Mortensen, 2004b).

Investigations have also addressed the written narratives of adults with a history

of specific language impairment and learning disorders. These studies have adopted

different linguistic foci for examination. For example, Smith-Lock & Nickels (2005,

2006, Smith-Lock, Nickels, & Mortensen, this issue) examined grammatical

complexity, semantic content and accuracy of spelling and punctuation in stories

written by adults with Language Impairment. They found that as a group, the adults

with Language Impairment showed no difference from the comparison group in the

length of their stories as measured by total words and total utterances (T-units).

However, there were group differences on measures that assessed grammatical

complexity, measured by mean length of T-unit, as well as accuracy of grammar,

spelling and punctuation, with Language Impaired subjects performing below the

comparison group. Individual profiles of the writers with Language Impairment

indicated substantial variability.

Narrative ability, both written and spoken has also been identified as problematic

in adolescents with Learning Difficulties (Gregg & Hoy, 1990; Reed, Patchell,

Coggins, & Hand, 2007; Wong, 2000). Wong (2000), in a paper that describes

strategies in expository essay instruction, reports on the different perspectives that

writing research has taken over time in relation to adolescents with Learning

Difficulties, including an initial focus on spelling and punctuation, followed by

attention to the cognitive processes involved in written text production. Wong

discusses the importance of expository as well as narrative discourse in the

educational setting and, together with other researchers (e.g., Englert, Raphael,

Fear, & Anderson, 1988; Englert & Thomas, 1987; Wong, Wong, & Blenkisop,

1989), outlines a number of features that are typical of the learning disabled

adolescent writer. These include delay in expressing ideas, concern with spelling

errors when editing rather than clarity and organization of content, unproductive

word finding strategies, poor spelling and punctuation, poor knowledge of paragraph

structure and logical organization of ideas. These features imply that problems for

the adolescent with Learning Difficulties exist for both cognitive, and linguistic

aspects of discourse production. Gregg and Hoy (1990), however, report different

findings in a study that examined organizational and linguistic features in expository

essays written by 35 college students with a history of Learning Difficulties, when

compared to normally achieving writers. Essays were analyzed in terms of cohesion

and coherence and their relationship to text organization. The writers with Learning

Difficulties demonstrated a good understanding of principles of text structure,

similar to the normally achieving writers. Their cohesive referencing ability was

also similar to normal writers, making effective use of pronouns for referencing and

selecting a wide range of pronoun types. Gregg and Hoy (1990) report that these

strengths were evident in spite of spelling and punctuation errors.

These varied findings confirm the knowledge that writing is a complex process

and that different levels of language (i.e., spelling, lexico-grammar and text

organization), as well as different types of texts may be usefully examined to

identify and explain patterns of difficulty that characterize written discourse by

adults with Language Impairment. The purpose of this study was to extend our

understanding of the nature of narrative writing difficulties of adults with a history

of Language Impairment by looking beyond the clause level phenomena examined

by Smith-Lock and colleagues (2005, 2006, this issue). The aim was to investigate

the integrity of text structure for a narrative task and to explore grammatical and

lexical abilities for the creation of a coherent text. The study took a functional

linguistic approach, which provides a number of perspectives from which to

examine language form in terms of various strata including word, clause and text

levels. This framework has been adopted for the teaching and evaluation of text

writing in primary education (Christie & Martin, 1997; Derewianka, 1992), in adult

literacy, both remedial and second language acquisition, (Hammond, Burns, Joyce,

Brosnan, & Gerot, 1992), and for the investigation of written communication

disorders in adults (Gregg & Hoy, 1990; Mortensen, 2004a, b).

Method

Participants

Ten adults with a history of childhood Language Impairment (3 women and 7 men)

took part in the study. Their ages ranged from 18 to 54, with a mean age of 27 years

(SD = 11.12). A comparison group included 30 university students, participating

for course credit. This group was a randomly selected subset of the comparison

Narrative texts in language impairment 737

123

subjects participating in the study of grammatical skills in narrative writing by

Smith-Lock et al. (this issue). These participants had no history of Language

Impairment or reading/writing difficulties, and their ages ranged from 18 to

55 years, with a mean age of 22 years (SD = 8.7). All participants were native

speakers of Australian English.

Language Impaired participants were recruited in two ways: (1) from past

clinical records or (2) from self-reported history of Language Impairment with

evidence of current oral language difficulty. The two different recruitment

procedures were used to generate sufficient numbers for the study, given the

paucity of clinical records available for follow-up. Self-reported history as a means

of identification has been used in pedigree studies of specific language impairment

(Plante, Shenkman, & Clark, 1996; Rice, Haney, & Wexler, 1998; Tallal et al.,

2001). These selection procedures consistently identify more family members with a

self-reported history of Language Impairment in the affected group than in a

comparison group with no Language Impairment. Interestingly, self-report has been

found to identify fewer affected family members than testing (Plante et al., 1996),

suggesting that self-report, if anything, might under identify rather than over

identify participants as affected. Nevertheless, on a case by case basis, individuals

identified by self-report do not always coincide with individuals identified by testing

(Rice et al., 1998). For this reason, it was decided to use both self-report and testing

in adulthood in those cases without documented clinical history. The legitimacy of

the ‘self-report ? current testing’ in the study was bolstered by the fact that in all

but one of the self-reported cases, the participant had a child with specific language

impairment for whom clinical records were available, suggesting a familial pattern

(the third participant did not have children). The combination of recruitment

methods, while not ideal, resulted in rigorous participant selection. Any error made

was likely to be in the omission of an appropriate participant due to potentially

‘resolved’ Language Impairment resulting in no oral deficits in the current battery in

spite of self-reported history and affected offspring.

Thus, participants were selected if they met one of the following two selection

criteria.

1. Documented evidence of childhood developmental language difficulty (n = 7).

Five of these participants were invited to participate after their childhood files

were reviewed at a local speech pathology clinic. One was referred by a

community speech pathologist. The final participant in this subgroup contacted

the researchers due to concern over his language skills.

2. Self-report of childhood developmental language difficulty, corroborated by

evidence of oral language difficulty as an adult (n = 3). Two of these

participants were parents of language-impaired children taking part in another

study and who reported histories of childhood language impairment themselves.

The remaining participant reported a history of language difficulties when he

was recruited for the comparison group.

All LI participants completed the following oral language tests:

1. Boston Naming Test (Kaplan, Goodglass, & Weintraub, 1983)

738 L. Mortensen et al.

123

2. Sentence Repetition subtest of Test of Adult and Adolescent Language-3(TOAL-3, Hammill, Brown, Larsen, & Wiederholt, 1993)

3. Non-word Repetition Test. This test consisted of a total of 30 words: 10 two

syllable, 10 three syllable and 10 four syllable words taken from Gathercole,

Willis, Baddeley, and Emslie (1994). Z-scores were calculated based on the

performance of the comparison group.

Individual participant details can be seen in Table 1. All Language Impaired

participants except one received a below normal score on two or more of the above

language measures, with 5 of the 10 scoring below normal on all 3 measures

(participants 3, 5, 6, 9 and 12). The one participant who scored below normal on the

Boston Naming Test only (participant 1) had a confirmed history of childhood language

impairment, including placement in a primary school language impairment class and

assessment as an adolescent by a community speech pathologist. Participants’ formal

education ranged from grade 7 to post high school (university or technical college).

Procedure

Participants were asked to handwrite the story of Cinderella, with no time constraint.

Their instructions were to ‘‘Write the story of Cinderella in as much detail as you can.’’

The stories were then transcribed into a computer file and analyzed for their text

structure and organization, and linguistic features of cohesion, both of which

contribute to the coherence of a text (Eggins, 1994). An analysis of the grammatical

features of the stories is reported in Smith-Lock et al. (this issue).

Generic structure analysis (GSA) was selected to evaluate text structure and

organization. GSA describes the structural elements of a text according to the text’s

purpose. Different text types have uniquely defining structures, which include

obligatory (core) and optional (elaborative) elements that occur in a particular order

(Hasan, 1996). A text is perceived as well organised and complete if it contains all

of the obligatory elements in the appropriate order. Drawing on Hasan’s framework,

a generic structure statement for the Cinderella story was established which

encompassed core obligatory content, based upon the classic version of the story by

Charles Perrault (Ehrlich, 1986). Obligatory elements included Introduction, which

names Cinderella and describes how she lives with her stepmother and stepsisters

and their harsh treatment of her. This was followed by Complication which

embodies a sequence of events associated with a ball that Cinderella attends,

Resolution, which provides a logical outcome of the activities associated with the

ball, and Conclusion, which describes the overall outcome or conclusion to the

story. Optional elements included Placement which identifies the narrative as a fairy

tale as well as additional orienting information, such as events leading to Cinderella

living with her stepmother and stepsisters, and Coda which evaluates the whole

story and may provide a moral. Details of the generic structure and related content

are outlined in Appendix Table 4. Stories were analyzed with respect to:

(i) Structural completeness, i.e., presence of obligatory elements.

(ii) Elaboration of the text structure, i.e., presence of optional elements.

(iii) Logical development of the text, i.e., appropriate ordering of elements.

A Cohesion analysis, based on the work of Halliday and Hasan (1976), was also

undertaken. Cohesion refers to the way in which a text holds together to form a

coherent whole. A coherent text demonstrates continuity of topic, reference, and

ideas. Cohesion involves a set of linguistic resources—lexical and grammatical, for

linking one part of a text to another, thus forming the foundation of coherence in a

text. Lexical cohesion refers to the cohesive effect achieved by selection of

vocabulary, established through relationships of reiteration or collocation. Reiter-

ation involves the use of repetition, synonyms, antonyms, hyponyms (i.e.,

taxonomic relations such as family: father mother, children), or meronyms (i.e.,

part-whole relationships, such as house: cellar). In this study meronyms and

hyponyms were merged into the broader category of super/subordinate relations.

Collocation refers to lexical items which regularly co-occur, or are causally related,

(such as magic spell; hum music). Grammatical cohesion includes, among other

resources, referencing through the use of pronouns, definite articles, demonstratives,

and comparatives. Stories were analyzed for:

i. The total number of lexical and grammatical tokens—known as Total tokens.A token is a content word used either specifically in the text or interpreted

through an implicit cohesive device.

ii. The number of grammatical and lexical tokens entering into cohesive chains—

known as Relevant Tokens.1

iii. The number of grammatical tokens forming reference chains (grammatical

relevant tokens)

iv. The number of lexical tokens entering repetition, synonym, antonym, super/

subordinate and collocation chains (lexical relevant tokens).2

Inter-rater reliability for 20% of the stories (5 Language Impaired texts and 3

comparison texts) was undertaken by two independent raters. Percentage agreement

for the Generic structure analysis was 96. Percentage agreement for the Cohesion

analysis was 98.1

Results

Generic structure analysis

Results of the generic structure analysis are presented in Table 2. The high mean

number of obligatory elements included indicates that, overall, both groups

produced structurally complete texts. On average, the groups included one (out of

two) optional elements. A mixed analysis of variance with one between groups

factor (group: Language Impaired, comparison) and one within groups factor

1 When calculating relevant tokens, the initial token and all related subsequent tokens (grammatical &

lexical) are included in the relevant token count.2 When calculating the lexical and grammatical tokens which form chains, the initial token is excluded

because there may be a number of chains associated with it, e.g. Cinderella- (Initial token) may have a

related repetition chain (Cinderella), a reference chain (she, her), a super/subordinate chain (young girl/

Cinderella; Cinderella/foot;). Therefore, including the initial token could artificially inflate the count.

Narrative texts in language impairment 741

(element: obligatory, optional) indicated no significant group 9 element interaction

(F(1,38) = 2.48, p [ .05) and no significant main effect for group (F(1,38) = 1.19,

p [ .05).

Individual analysis

Each individual’s scores were compared to the comparison group’s scores using

z-score comparisons. Four of the 10 Language Impaired participants (40%) were

significantly different from the comparison participants (Modified t-test, p [ .05,

2-tailed, Crawford & Garthwaite, 2002). This reflects three Language Impaired

narratives (30%) which omitted one obligatory element (P2, P9, and P10) and one

Language Impaired narrative (10%) that omitted two obligatory elements (P6).

However, it should be noted that four of the comparison participants (13%) also

omitted one obligatory element (C12, C13, C23, and C26). Nevertheless, the

difference in the proportion of participants per group who omitted obligatory elements

showed a trend towards significance (Fisher Exact test, p = 0.089, 1 tailed).

With respect to number of optional elements, three Language Impaired participants

(30%) included significantly fewer than the comparison participants, including no

optional elements (P4, P7, P9, t = -2.249, p = 0.032 2-tailed). However, four

comparison group participants (13%) also wrote narratives including no optional

elements (C11, C22, C24, C26). The difference in the proportion of participants per

group who omitted optional elements was not significant (Fisher Exact test,

p = 0.228, 1 tailed).

Examples of texts analyzed for generic structure are presented in Appendix

Table 5–7. These include Language Impaired participant P7 who showed complete

generic structure, Language Impaired participant P6 who omitted two obligatory

elements, and comparison group participant C26 who omitted one obligatory

element.

Errors

As a reflection of logical development of the text, stories were examined for

appropriate ordering of the story elements. One subject from each group: P7

(Language Impaired group), and C26 (comparison group), demonstrated inappropri-

ate ordering of the story elements (see Appendix Table 5–7). P7 in his unelaborated,

yet structurally complete, text introduces the godmother (element 3) before

introducing or describing the ball (element 2). The following elements, however,

are in keeping with the established story sequence. In the case of C26, the introduction

is followed by an incomplete complicating event, which is out of sequence [One day

she met a fairy God-mother who told her that she would be able to go to]. This

incomplete event comes too early in the story (i.e., in the original story, Cinderella is

invited to the ball and is told she cannot go before the fairy godmother appears). The

fact that the sentence was incomplete suggests that this was perhaps a false start, with

no explicit repair. This, together with a slightly different interpretation of the story,

renders the text initially confusing and somewhat disjointed.

In sum, group comparisons of generic structure found no significant differences

between the Language Impaired and comparison groups. Individual analyses

indicated that members of both groups omitted obligatory and optional elements.

Nevertheless, a greater proportion of Language Impaired group members than

comparison group members omitted elements, either obligatory or optional, from

their narratives.

Cohesion analysis

Results for the cohesion analysis can be seen in Table 3. The number of relevant

tokens (i.e., lexical or grammatical tokens entering chains subsequent to an initial

token) was divided by the total number of grammatical and lexical tokens in the

narrative in order to control for narrative length across participants in all analyses.

A mixed analysis of variance with one between groups factor (group: Language

Impaired, comparison) and one within groups factor (number of subsequent tokens

entering cohesive chains: grammatical, lexical) indicated no significant chain by group

interaction (F(1,38) = 0.75, p [ 0.05), no main effect for group (F(1,38) = 0.25,

p [ 0.05) but a significant main effect for chain type (F(1,38) = 51.46, p [ 0.001).

Thus, the groups did not differ significantly in the number of tokens in cohesive chains.

However, significantly more tokens were involved in lexical chains than grammatical

chains. This is to be expected, by the nature of the large range of lexical relationships

possible as opposed to the more restricted range of grammatical relationships that have

the specific function of reference.

In order to examine the type of lexical chains used, a mixed analysis of variance

was undertaken, with one between groups factor (group: Language Impaired,

comparison) and one within groups factor (number of subsequent tokens per chain

type: repetition, synonym, antonym, super/subordinate, collocation). Number of

tokens for each chain type was divided by the total number of lexical tokens in

cohesive chains in order to control for number of lexical chains established. There

was no significant group by chain type interaction (F(1,38) = 1.9, p [ 0.05), but a

significant main effect for chain type (F(1,38) = 909.16, p [ 0.001). Inspection of

the data indicates that the majority of lexical tokens in cohesive chains were

involved in repetitive chains.

A series of independent group t-tests compared the use of each lexical chain type

between the groups. Significance levels were adjusted using the Bonferroni correction

for repeated t-tests. No significant differences were found (repetition: t(38) = 1.1,

p [ .01; synonym: t(38) = 1.39, p [ .01, antonym: t(38) = 1.61, p [ .01; sup/

subordinate: t(38) = 0.67, p [ .01; or collocation: t(38) = 0..72, p [ .01). Thus, the

groups did not differ significantly in the number of tokens involved in the various chain

types.

Individual analysis

Each individual’s scores were compared to the control group’s scores using

Crawford and Garthwaite’s (2002) modified t-test. One Language Impaired

participant had a significantly smaller proportion of relevant tokens than the

control group (P8, proportion of total tokens that are relevant tokens = 0.48; t =

- 2.07, p = 0.037, 2-tailed). However, two participants in the comparison group

had similarly small proportions (C1, 0.38; C6, 0.45). No Language Impaired

individual showed a significantly different distribution of cohesive chains across

lexical and grammatical chains compared to the comparison participants.

Analysis of the types of lexical chains used, indicated substantial individual

variation in both groups. This variability is due, in part, to the small overall numbers

of lexical cohesive chains of types other than repetition. There were very small

numbers of cohesive chains, particularly for synonomy, antonomy, and super/

subordinates. Hence, due to the small numbers of items in these categories

individual analyses are inappropriate. We will therefore focus on repetition and

collocation. In the use of repetition as a cohesive device, none of the Language

Impaired participants used significantly more repetition in lexical cohesion than the

comparison group. One Language Impaired participant (P2) was outside the range

of the comparison group although only significantly different from the mean on a

one-tailed test (t = 1.722, p = 0.048, 1-tailed; p = 0.096, 2-tailed). With respect to

use of collocation, one of the Language Impaired participants was significantly

above the comparison group mean (P5, t = 1.967, p = 0.029 1-tailed, p = 0.059,

2-tailed) although not outside the range (two comparison group participants used a

higher proportion of collocation).

Examples of the different lexical categories selected by the Language Impaired

and comparison groups are presented in Appendix Table 8.

Errors

Errors of reference were observed only in the Language Impaired group. Three

Language Impaired participants demonstrated one instance each of problematic

reference, which resulted in reduced clarity and coherence within the texts. The

example from P3 below shows difficulty establishing correct reference for the

pronoun they.

P3 and the prince went to her house and her sisters try the slipper on they didn’tfitthere feet. So Cinderella went to try it on and they lived very happily after

In the first instance, the use of the plural rather than the singular pronoun makes

they refer to the sisters when the full sentence they didn’t fit there feet indicates that

the intended reference was the slipper. The difficulty is compounded in the

following sentence by the use of they again, here without a clearly established

antecedent. Possible antecedents include (i) the previous they, already confused

between the sisters and the slipper, (ii) Cinderella, the subject of the previous

clause, which would require the singular pronoun she, and finally, (iii) the clearly

Narrative texts in language impairment 745

123

intended, but unstated antecedent, Cinderella and the Prince. The inexplicit use of

they requires knowledge of the story in order for it to make sense to the reader.

The example from P7 below also contains problematic pronoun reference.

P7 The three stepsister and cinderella and the godmother come out and made awhisper and she go to the dance

Here, a pronoun was used to refer to a portion of a noun phrase, rather than a

complete noun phrase. P7 has written she, clearly intending the reference to be to

cinderella. However, the structure as written forces she to refer to [the threestepsister and cinderella and the godmother]. Even if the segment [the threestepsister and cinderella] is ignored as an incomplete sentence, and the sentence re-

started with [and the godmother], she must then refer to the godmother, not

cinderella. As with the above text (P3), knowledge of the story is required to resolve

this reference.

Discussion

This study sought to characterize the written narrative skill of adults with a history

of Language Impairment. Ten adults with a history of Language Impairment and 30

participants with no history of Language Impairment were asked to write the story

of Cinderella. It had been established that this group of Language Impaired adults

demonstrated problems with syntax, spelling and punctuation (Smith-Lock &

Nickels, 2005, 2006; Smith-Lock et al., this issue), but features of textual structure,

organization, and coherence had yet to be explored.

Stories were analyzed with respect to generic structure and cohesion. Group

analyses found no significant differences between the groups in generic structure or

cohesiveness of the stories. Individual analyses of generic structure indicated that a

greater proportion of the Language Impaired participants omitted obligatory and/or

optional elements from the story than participants in the comparison group.

Individual analyses of cohesion indicated that Language Impaired participants were

no less likely to use cohesive chains in their narratives than participants in the

comparison group, nor to differ in the relative proportions of grammatical and

lexical chains, or lexical chain type. Errors of generic structure occurred in both

groups. Errors of grammatical reference, however, only occurred in the Language

Impaired group.

The most notable finding was that, on average, both generic structure and

cohesiveness were relative strengths for the Language Impaired group. Individual

variation existed, but rarely fell outside the range of the comparison group’s

performance (only for one participant in the case of the use of repetition). This

strength of generic structure and cohesion was remarkable when taken in the context

of the sometimes substantial clause level grammatical difficulties demonstrated by

some Language Impaired participants. P7, for example, included all obligatory

elements and did not differ in the proportion of tokens in the narrative involved in

cohesive chains, in spite of severe grammatical difficulties.

746 L. Mortensen et al.

123

One point of difference did arise. Although errors of reference occurred

infrequently, all such errors were made by Language Impaired participants.

Interestingly, two of the three errors involved pronominal reference, a grammatical

technique linking phrases within and between clauses. Thus, the Language Impaired

participants’ errors of cohesion were of a grammatical nature, consistent with the

grammatical deficits shown in other areas (cf. Smith-Lock et al., this issue).

Nevertheless, for the most part, use of pronouns did not present consistent

difficulties within the Language Impaired group. In this case the findings are similar

to those reported by Gregg and Hoy (1990) with respect to the effective use of

pronouns for referencing in essays written by young adults with Learning

Difficulties.

The lack of group differences in generic structure and cohesion suggests that

narrative structure is a strength for the Language Impaired participants. Of course, it

is possible that the task itself i.e., the story of Cinderella, which was chosen because

of its cultural relevance and familiarity, may have been too simple or well rehearsed

to challenge the writers’ strengths and deficits. A number of researchers suggest that

the type of stimulus used may have a significant effect on the complexity of stories

produced by children (e.g., Liles, Duffy, Merritt, & Purcell, 1995; Pearce, 2003).

The same consideration also applies to adults. Furthermore, the framework

established to analyse text structure was relatively simple, and required minimum

information, in short, the ‘bare bones’ of the story. It is possible that different results

would be obtained if a more substantial degree of information were required. For

example, Reed et al. (2007) examined spoken narratives of younger and older

adolescents with specific language impairment for their informativeness, using the

categories of relevance, irrelevance and inaccuracy. Their findings suggested that

adolescent speakers with specific language impairment tended to give more vague

responses in their narratives in comparison to normally developing adolescents. In

the analysis adopted for this study, both explicit (accurate) and implicit (vague)

expression of structural elements were accepted. A more stringent requirement for

explicit information may have provided different outcomes.

Secondly, from a functional linguistic perspective, the choice of narrative over a

different style of text may have affected the results. Different functional text types

place different cognitive and linguistic demands on the writer (Halliday & Hasan,

1985). The purpose of a narrative is to entertain and to teach cultural values (Butt,

Fahey, Feez, Spinks, & Yallop, 2000). A narrative constructs a pattern of events

with a problematic and/or unexpected outcome, and is structured for the most part in

a temporally sequenced manner, using mostly additive, temporal and some causal

connectives to develop the story. Expositions, on the other hand, aim to argue and

persuade and are consequently organised in a rhetorical manner, relying more

heavily on causal and additive connectives to construct the argument (Eggins, 1994;

Martin, 1985). While narratives may contain verbs of action, expositions are likely

to employ verbs of thinking and feeling, together with attitudinal vocabulary and

modality to indicate the writer’s attitudes. Hence a more varied sampling of data to

include texts types that elicit varying cognitive and linguistic abilities would

provide further insights into the relative strengths and deficits of adults with

Language Impairment.

Narrative texts in language impairment 747

123

The apparently limited range of lexical variety demonstrated by both groups in

the small numbers of cohesive chains for synonomy, antonomy, and super/

subordinates could be a consequence of the choice of text, i.e., the Cinderella

narrative which may have dictated word selection and constrained lexical variety. A

different text type or more spontaneous narrative may provide a greater potential to

elicit a wide range of word choice and patterns of cohesion. The Cinderella story,

nevertheless, had the strength that it was able to achieve consistency across the

narratives. In so far as can be controlled, each individual was writing with the same

target story in mind, allowing direct comparisons across groups.

Future research should examine other text types to determine if Language

Impaired participants’ strength in text organization in the writing of a familiar fairy

tale carries over to more challenging situations such expository text. Comparison of

the written texts to parallel oral samples should also be carried out to see if similar

patterns of strength emerge in the oral narratives of Language Impaired individuals.

In conclusion, patterns of text organization at the level of generic structure and

cohesion did not distinguish the performance of Language Impaired writers from the

non-impaired participants. Both groups showed variability across individuals, with

the Language Impaired narratives more likely to contain errors or a restricted

variety of lexical cohesion. It is suggested generic structure and cohesion are a

relative strength in the writing of adults with Language Impairment.
