The LD first graders were found to have a lower level as well as greater variability in their understanding of basic concepts. The greatest discrepancy of the LD group was found on concepts of quantity, space, and miscellaneous, respectively. (Author)

A nonverbal assessment procedure designed to characterize cognition using a Piagetian framework was administered to six autistic children, (4.8 to 15.2 years old). All six children evidenced competence beyond sensorimotor Stage VI and demonstrated cognitive functioning between the periods of early preoperational and concrete operations. (Author)

Uncertainty was researched as a perceptual structure which mediates the transition from sensorimotor activity to language. The guiding notions are that the attentional system is geared to uncertainty from the beginning of life and that a speaker's language use is coordinated with this system as it emerges. (Author)

The social-cognitive skills of 38 retarded children ages 24 to 92 months were assessed on a set of communication tasks. Results indicated that the social-cognitive skills of both retarded and nonretarded children were related to social age. (Author)

Children took a group test of disjunctive reasoning containing 48 inclusive and exclusive items varying in content of the premises, and affirmation or negation of the conclusion. Performance improved until seventh grade. Negative conclusions produced more correct answers. Implications were discussed in relation to cognitive developmental theory…

A chronological listing (1938-1978) of 78 published works by Professor Edwin Peel of the University of Birmingham, England. (SJL)

The difficulties encountered in attempting to apply Piaget's theory of cognitive development to education reveal ambiguities existing within the theory itself. Research activity by educators and by developmental theoreticians must be integrated in order to achieve either a comprehensive developmental theory or an effective application of it. (CT)

Comprehension of usages of "or" was investigated in children 5 to 6 and 9 to 10 years old, and in college students. All age groups made logical inferences involving "or". All age groups perceived contradictions but disagreed regarding inferences to be drawn from contradictions. Except when set union is indicated, "or"…

The training of intelligence is considered as a component of early interventions. The Home-Oriented Preschool Educational (HOPE) experiment is examined, and a currently in progress long term followup study of it is described. (Author)

A theory of cognitive modifiability deals with the phenomenon of low cognitive performance, explains its etiology, and forms the basis for a remedial intervention--Instrumental Enrichment (IE)--that induces changes of a structural nature in adolescents. (Author)

Twenty activities which develop gifted children's creativity; power of reasoning; and ability to analyze, synthesize, and evaluate are listed. (DB)

The study examined 30 schizophrenic and 30 nonpsychotic but disturbed children (all residents at a psychiatric center and all between 8 and 17 years old) for cognitive deficits in logical thinking, symbolic imagery, and conservation within the Piagetian theory of cognitive development. (Author/SBH)

Children at three levels of conceptual maturity were presented with six dilemmas in order to test the hypothesis that cognitive development predicts concrete behavioral choices whenever individuals are at least as complex as the moral alternatives confronting them. (Author/DB)

The ability of three- and four-year-old children to reason about the components of event sequences involving simple transformations was tested in two experiments. In Experiment I children saw picture "stories" of the form object, instrument, and transformed object, with one item deleted. In Experiment II only the instrument item was…
