Article describes results of a longitudinal study on measuring intelligence of infants. Results cast serious doubt on the notion of measuring general intelligence in the period of infancy. (PS)

This research studied the relation between mastery of the words "and" and "or" and performance on the conjunctive and disjunctive tasks. A definition test was used to measure level of mastery of the linguistic terms and a traditional logical test to measure logical task performance. Results are related with ability to solve logical tasks.…

This booklet cites evidence indicating that intelligence can be trained, given a physiologically normal student and an intensely persistant tutor. Methodologies for increasing mental efficiency have in common the principle of coordination of physical and mental processes, whether achieved by simple relaxation training, brain polarization, or…

Reexamines Yoruba children from educated and traditional families after five years, finding that those growing up in a privileged environment showed increasingly superior mental scores. (Author/JM)

Two studies examined modifiability in intellectual functioning in older adults. The fluid-crystallized theory provided a theory base for the research. (Fluid intelligence follows a normative decline through adulthood, while crystallized intelligence remains stable or even increases.) In the first study thirty subjects (average age 69.2)…

Current research indicates the possible influence of IE development on cognitive development. Efforts are being made to identify behaviors by which parents or teachers can increase development of internal control expectancies in preschool children. Studies correlating children's IE scores with various mother behaviors or mother-child interaction…

Four models are discussed with which to view students, educational goals, and learning environments. Each of the four theories emphasizes a unique aspect of the total development process. Piaget's model describes the development of structures and processes which characterize mature logical thinking. Perry provides a closer look at students'…

The aim of this report was to provide teachers of preschool and early elementary school children with a brief summary of current psychological research and theory concerned with the development of cognitive skills in young children. Psychological research often provides a basis for procedures teachers use in the classroom. Each chapter of the…

The recent phenomenon of the "returning adult" to colleges has raised concern regarding two implications: age decline in intellectual ability and loss due to lack of practice. Literature indicates slight impairment of the problem-solving function until the years of advanced age. The degree of impairment is related to factors of educational…
