Executive functions (EF) are a group of interrelated complex mental abilities that are involved in planning and initiating goals and carrying them through despite interruptions. As these functions are typically higher-order and involved in integrating other, more basic, lower-order functions, they are difficult to assess directly, and executive…

Attempts to refute Riegel's (1973) claim that Piaget's formal operations distort reality for the sake of logic. It is suggested that Piaget's figurative-operative distinction is dialectical and that Piaget's theory is valuable precisely for its resolution of how a person remains internally ordered while adapting to the external world.

THIS STUDY DEALT WITH THE CONCEPT OF DEDUCTIVE LOGIC AND ITS USE BY ADOLESCENTS, AGES 10-18. TWO EMPIRICAL QUESTIONS OF CONCERN IN THIS STUDY WERE (1) THAT OF READINESS FOR MASTERY OF LOGIC AND (2) THAT OF THE NATURAL-CULTURAL DEVELOPMENT OF MASTERY OF LOGIC. TWO DEDUCTION TESTS WERE DEVELOPED, ONE FOR EACH OF THE TYPES OF LOGIC TREATED. THEY WERE…

The problem investigated was the relationship between cognitive category width and certain other cognitive and perceptual variables, with the intent of gaining additional insight into the effect which individual differences in cognitive conceptualization exert on certain other behaviors. Cognitive category width, defined as the score obtained on…

Corneal infrared photography was used to record the visual fixations of 24 infants (4-6 weeks and 10-12 weeks) exposed to simple geometric figures. The results are discussed in relation to developmental changes in responsiveness to visual figures and in increasing ability to process information. (JMB)

The author develops a model for adult cognitive development useful for providers of lifelong education. The model is based on a framework relating the receiving of information to gaining knowledge, leading to wisdom. (CH)

Studies children's inductive inferences in order to investigate the development of the expectation that members of a category share unforeseen properties. Results indicate that preschoolers drew more inferences based on category membership than on perceptual appearances. (PCB)

Critiques an earlier article by M. Frauenglass and R. Diaz reporting their study on the interaction between private speech and cognition. Argues that their interpretation fails to regard how private speech is seen to regulate cognitive activity within Vygotskian psycholinguistic theory. (HOD)

Presents several reconceptualizations of adult cognitive development and its relation to everyday problem solving. Argues that investigation of relations between adult cognitive development and everyday problem solving may be facilitated through causal modeling that includes task characteristics, social context, and personality and motivational…

Observations of supervisors with trainees on youth training programs showed that few learning skills were being developed. Six experimental training workshops were run; results indicated that supervisors who attended them showed a greater awareness of learning skills and how to develop them. (SK)

The effects of delay of information feedback interval (0 or 7 seconds), postinformation feedback interval (1, 8, or 15 seconds), difficulty (one or three variable irrelevant dimensions), and presence or absence of a tractor in the postinformation feedback interval were investigated with 240 junior high school children in a modified…

Administering of Kohlberg's adaptation of Pinard and Laurendeau's dream interview to 24 Hasidic boys aged 4 to 16 yielded data that failed to support the invariance of the process of emerging cognitive structures in the development of the dream concept and underscored the importance of cultural influences in affecting the sequence of cognitive…
