The purpose of this study was to investigate the influence of cognitive training (CT) using mobile applications on attentional control and impulsivity among pre-service teachers. Pre-service teachers were divided into two groups: experimental (n=25) and control (n=14) groups, they were selected from a large sample (n=718). Over 28 sessions, the…

Elevated levels of risky behavior in adolescence may signal developmental change in unconscious appraisal of risk. Yet, prior research examining adolescent risk judgment has used tasks that elicit conscious deliberation. The present study, in contrast, attempts to characterize age differences in (less conscious) intuitive impressions of risk.…

Generalizability theory was applied to the Matching Familiar Figures Test (MFF), an instrument commonly employed to assess reflection-impulsivity in children, in order to analyze the dependability of the MFF at four grade levels: second, third, fourth, and fifth. The MFF was individually administered to 114 boys. A completely crossed, two-facet…

The project report summarized here describes the interrelationships of the individually administered tests given to 820 Head Start children from three urban sites in the second year of a longitudinal study. These results are compared with those obtained in Year 1, the year prior to the students' attendance in a group program. The tests tapped…

Two techniques were used to modify an impulsive conceptual tempo on a visual discrimination task. The subjects were 42 first grade white children who had previously been classified as impulsive or near-impulsive on the Matching Familiar Figures Test given to 82 children. These subjects, who had scored above the median on errors and below the…

Age-related and test-retest changes in reflection and impulsivity were investigated among preschool and school age subjects and senior adults. A study of each age group was conducted using either the Matching Familiar Figures test (MFF) or the Kansas Reflection-Impulsivity Scale for Preschoolers (KRISP). In all three studies the procedure was to…

A three-year longitudinal study was conducted with 895 Head Start children to examine the development of self-regulatory abilities during the preschool years. The purpose was to discover, given the behaviors measured, whether there is convergent and discriminant validity for the existence of one or more dimensions of self requlatory behaviors…

Performance of 162 children, ages five to seven, on concept formation and perception tests indicated that enforced delay in responding minimally affected all reflective subjects and impulsive boys; impulsive girls improved.
