This report evaluating the Kansas Reflection-Impulsivity Scale for Preschoolers (KRISP), developed as an easier task version of the Matching Familiar Figures Test for school-age children, presents an analysis of data on 1,408 children of widely varying backgrounds. Eighteen samples of children, ranging in age from 2 years and 5 months to 6 years and 8 months, were studied by investigators in the United States, England and Australia. The KRISP consists of 5 practice items and 10 test items on each of 2 forms. Each item presents a standard line drawing of a common object, together with 4 to 6 similar alternatives, only one of which is an exact duplicate of the standard figure. The child is asked to indicate the duplicate, and latency to first response and number of errors are recorded. For purposes of normative analysis, subjects were grouped according to four age intervals. Results are presented on age, sex and other effects, on test-retest reliability, inter-form agreement, validity, normative analysis, sample differences and demographic characteristics related to cognitive style. The report concludes with a discussion of results, examining the speed-accuracy trade-off and choice of strategy, and cognitive development and practice-familiarity. Although the KRISP is seen as a useful research tool, its use for clinical or educational diagnostic purposes with individual children is not recommended in the absence of additional evidence of validity.
