Examines the effects of adult age on response interference with organized recall with adults 20-80 years old. Results are discussed in terms of several explanations of response interference both with discrete recall of single items and with organized recall. (Author/ED)

Toys were ranked for attractiveness by preschool and fourth grade children, both before and after one toy was forbidden. Results suggest that a perceived association between an object's being forbidden and its being attractive may be learned through the course of socialization. (Author/ED)

Presents a valid measure of locus of control constructed for 4- to 8-year-old children. Includes data reflecting achievement, interpersonal distance, and social desirability. Future research directions are specified. (Author/SDH)

Two experiments study the effects of age and sex on the ability of 3-1/2- to 6-year-old children to use nonverbal cues in identifying affiliative relationships. (SDH)

Discusses two experiments in which middle-aged, elderly, professional, and non-professional males and females were given the Conceptual Styles Test.

The development of ordering and correspondence operations, under varying degrees of the presence of length cues to number, was studied in 91 preschool children. Findings are interpreted in terms of the young child's difficulty in separating and coordinating the dimensions of length and number. (Author/ED)

The utility of Heider's model for specifying relations between perceived properties of an act and the attributed intentionality of the act is explored empirically with children of varying ages. (Author/ED)

Examines the effects of age and of incidental-learning tasks on recall of a categorized word list by two groups of adults (18-30 years and 55-65 years). (ED)

This study demonstrates that, given the assumption that the child does have some understanding of both height and amount, many nonconservers do give correct reversal judgments for both. Also, reversibility data from this study do not support the theory that a new stage appears when water conservation judgments appear. (Author/ED)

Both forms of the Muller-Lyer illusion were presented to the normal and retarded subjects to determine possible changes in illusion strength in either or both forms of the illusion when age, amount of repetition, and IQ were varied. (Author/ED)

Reports responses to a 100-item behavior inventory from white, black, Oriental, and Chicano mothers, constituting a nonclinc sample of over 3,000 children, aged 9 to 11 years. Comparisons with seven other American and British studies show agreement in problem prevalence. Data tables are included. (Author/ED)

Presents a study of the cumulative deficit hypothesis and a discussion of some of the theoretical issues and methodological problems involved. Results of the study indicate a significant age decrement in verbal, but not nonverbal, IQ among a large sample of Negro elementary school children. (Author/ED)
