a single-subject research is a method of testing hypothesis.
sometimes referred to as single-case or N of one research.
What is Single-Subject Experimental research ?
o Repeated Measurements •also an observation of the individual.
Purpose: to determine if changes in the experimental conditions effect changes in the subject.
GENERAL PROCEDURES
o Baseline• Is analogous to a pre-test in group research design• Baseline data generally are collected by observing the aspect the individual’s behavior that is under study at several times prior to intervention.
oManipulating Variables
oLength of Phase
oTransfer of Training and Response Maintenance
o Target Behavior or focus of the research is usually determined by the research or real problem.
Purpose of assessing the target behavior:• first, determine the extent to which the
target behavior is performed before the program begins.
• Second, assessment is required to reflect behavior change after the intervention begun.
ASSESSMENT
oData Collection Strategies
Ways to measure such behaviors.• Frequency measure is simply a
count of the number of occurrences of the behavior observed during a given period of time.• Duration a time-based measure of
overt behavior• Time sampling or interval recording • Real-time observation
o A-B-A DesignA- represent a series of baseline measurement.
B- represent a series of measurements occurring during the treatment.
A-B-A • Baseline• Intervention•withdrawal
BASIS DESIGN
A-B-A-B design examines the effect of an intervention by altering the baseline condition(A phase), when no intervention is in effect, with the intervention condition (B phase)
o Multiple Baseline Design• Interventioneffect is demonstrated by having more than one baseline.
oOther Design• Alternating treatment or Multiple treatment design permit the researcher to compare two or more treatment while controlling for possible order effects.
