Test of Perception of Differences (CARAS-R): Analysis in A Sample of Peruvian Children and Adolescents

Abstract

Objective: To examine differences in distributions of sustained attention (SA), impulsivity control index (ICI), errors of commission (Ec) and errors of omission (Eo) with respect to demographic variables (sex and school grade). To analyze differences at the secondary level in the regions of Peru. To relate age and school grade with AS and Eo. Theoretical framework: The study is centered on the theoretical model of Posner and Petersen (1990); considering a neuropsychological approach to development and a visual search paradigm. Method: It belongs to a quantitative approach, with a descriptive correlational scope and cross-sectional non-experimental design. The sampling was probabilistic by clusters, 6,564 students at the primary level and 4305 at the secondary level. Results and Discussion: In AS, ICI, Ec and Eo there are statistical differences according to sex and school grade. On the other hand, there were associations between AS and Eo according to age and school grade. Finally, statistical differences were obtained in AS, ICI and Eo according to the three regions of Peru. Implications of the research: The study provides new scientific evidence of attention in Peruvian children and adolescents. Originality/value: The study is based on the typification of the instrument in the Hogrefe TEA editions publishing house (Spain). Likewise, the results presented are unpublished and contribute to provide new information for psychopedagogues, psychologists and educators.
