On the basis of longitudinal data across 9 years, this study examined the contribution of sustained attention and executive function to the poor cognitive and socioemotional adjustment of school-age children whose mothers had depressive symptoms during the child's infancy. Mothers (N = 1,364) reported depressive symptoms across their child's…

This study examined the development of flexibility and abstraction in preschool children by using a newly designed Pattern Completion Task (PCT) and the Flexible Item Selection Task (FIST). In the PCT, children were presented with an incomplete pattern consisting of different-colored shapes and were asked to select the colored shape that…

This study compared the cognitive control skills of male incarcerated adolescents (n = 44), male control adolescents (n = 33), male incarcerated young adults (n = 41), and male control young adults (n = 35) using the AX-continuous performance test (AX-CPT). This test measures proactive control (the ability to maintain a mental representation of…

This study reports the preliminary results from a field test of the College-readiness Performance Assessment System (C-PAS), a large-scale, 6th-12th grade criterion-referenced assessment system that utilizes classroom-embedded performance tasks to measure student progress toward the development of key cognitive skills associated with success in…

The general objective of this study was to study Piaget's notion of the sequential development of number conservation in 85 children averaging 5.9 years of age. The question addressed was to determine if a set of ten equal addition conservation of number tasks were scalable. A large coefficient of reproducibility, .912, was computed. Other indices…

In two experiments, 5- to 13-year-old children mentally tracked the rotation of a pointer around a circular backdrop to indicate the pointer's imagined position on a backdrop at the sound of a signal. Results indicated that children older than eight years generated linear distance x time functions indicating mental tracking but that younger…

In the present study, the authors explored age differences in event-based prospective memory (PM) across adolescence. The tasks consisted of an ongoing task (OT; i.e., personality questionnaire items, math problems) and an embedded prospective task that required participants to remember to make a special response whenever they encountered a PM cue…

Baumeister's (1968) hypothesis that mentally retarded children exhibit depressed levels of performance and greater intra-individual variability when compared to intellectually non-handicapped children of similar chronological age was investigated. Eight 10-year-old educable mentally retarded boys and 16 non-handicapped boys, matched by either…

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…

Examines several possible difficulties in interpreting the results of studies which employ Piagetian tasks, especially conservation tasks, with older individuals. Notes that Piaget's clinical method allows more flexibility in the assessment of competence than do more quantifiable techniques. Examines the possibility of task misinterpretation by…

The purpose of this study was to determine (1) whether the development of combinatorial schema as defined by Piaget is dependent on, or independent of, instruction, and (2) whether or not a prescribed treatment compatible with contemporary learning theories can develop the combinatorial operational abilities of students who are in a transitional…

This research study is designed to determine (1) to what extent educationally low achieving inmates differ in their cognitive performance from high achieving inmates, and (2) if such differences exist, to what extent can the level of cognitive performance in the former group be modified in a positive direction by a specific learning experience.…

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…

Forty-two volunteer subjects, mostly young adults, participated in developing a methodology for studying cognitive processes and cerebral lateral functions in relation to individual cognitive styles and age. Four test batteries were developed and refined in this study: the adult cognitive, the adult electroencephalogram (EEG), the children's…
