Compares the linguistic performance of the students in three grades exhibiting different levels of performance on five selected Piaget-type tasks, and identifies those tasks which differentiated significantly between the cognitive levels and the linguistic performance of the subjects. (Author/GA)

A look at how behavioral objectives are related to learning curves. Definitions and major uses are noted. Havighurst's development tasks are presented as a model for providing better retention of learning. Also includes a brief look at the infant science'' of Psychometrics. (Author)

A COMPARATIVE, LONGITUDINAL STUDY WAS CONDUCTED TO EXAMINE SPECIFIC PERFORMANCE CHARACTERISTICS OF DEAF AND NORMAL CHILDREN ON SELECTED COGNITIVE TASKS. THE SAMPLE, DISTRIBUTED INTO 3 AGE CATEGORIES, CONSISTED OF 72 NORMAL AND 60 DEAF CHILDREN. MEASURES WERE SELECTED TO ASSESS THE PERFORMANCE OF SUBJECTS (1) IN DIFFERENT AREAS OF COGNITION, (2) BY…

Hypothesizes that horizontal decalage, or the mastery of one task but not another formally similar to it, is an expected outgrowth of Piagetian theory. (MB)

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…

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…

A study is reported in which the effects of 2 competitive treatments on mean classroom performance, interest and retention were examined with the use of a 10-day vocabulary-learning task. Sixty-six 5th grade classrooms were randomly assigned to one of 3 conditions: (1) control; (2) competition with reward; and (3) competition in a game setting.…

The relationship among the Piagetian concepts of identity, seriation, and transitivity was explored with preschool subjects. (JMB)

Twenty-seven kindergarten children were trained on two different double classification matrix tasks in an attempt to determine whether the tasks were hierarchically related. Prior behavior analyses of the tasks suggested that the two tasks shared many components, but that the more complex task had in addition components not included in the simpler…
