Testing of a probabilistic model for the analysis of the Reflective-Impulsive cognitive styles was carried out on 178 school-age children. The model allows the sample be split into two groups of Cognitive Responders and Random Responders. Comparisons were made between groups at three age levels (8-yr., 10-yr., and 12-yr.-olds). Analysis indicated that Cognitive Responders scored better than Random Responders on a variety of measures, and group differences were related to children's developmental status. These results replicate and extend previous research with this model. Implications of random responses for research on reflection-impulsivity and the distinction between cognitive styles and cognitive development are discussed.
A probabilistic model of reflection-impulsivity as measured by the Matching Familiar Figures Test (MFFT) is presented and tested on 77 fourth graders. In testing the model two groups emerged, a random response group (n = 22) and a cognitive response group (n = 55), who use the evaluation process. Correlations among latencies, total errors, initial errors, school-scores, and IQs were compared for our total sample and the two groups. The correlation of MFFT latencies and errors disappeared for the random-response group and new correlations with errors appeared while the cognitive response group kept a statistically significant correlation of latencies with errors and no other error correlation was shown. This last group was classified by Kagan's median-split procedure showing that most reflective subjects kept their classification. Preliminary results suggest a reinterpretation of reflection-impulsivity literature, especially as related to the impulsive style.
The relationship between children's reflection-impulsivity styles and their human figure drawings was examined for a sample of Mexican children of middle (n = 97) and low (n = 110) socioeconomic status. Drawings were scored for Developmental, Emotional, and Impulsivity indicators. As in previous research with American preschoolers, the drawings of 23 Mexican preschoolers did not correlate with the styles; however, significant relationships between the styles and Impulsivity scores of older children of low status (n = 87) were also found, suggesting that, when a higher-level of impulsivity is present in a population, a relationship between styles and drawings may be observed. The findings for low-status preschoolers, even their higher Impulsivity scores, support the notion that Kagan's measure of impulsivity is not appropriate for use with younger children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
