Two studies were conducted to test incentive magnitude effects on free recall. Fifth and eighth graders and college adults were tested in conditions in which they were instructed to either rehearse overtly or engage in a counting task prior to the experiment. Results support theories emphasizing rehearsal as a mediator of incentive level effects…

Developmental changes in interpersonal perceptions in older siblings were studied in children in grades K, 2, 4, 6, 8. Older children used more abstract and more nonegocentric modes of description. (ST)

The development of the ability to selectively oppose fingers to the thumb and to localize digits was studied in preschool children. Competence increased with age. Results are discussed in terms of the development of body schemata and neuropathological conditions. (ST)

Exploratory and play behavior were studied in young children using three dimensional random polygon objects. (ST)

Recall, knowledge, and preference for masculine and feminine items were tested on 240 American 5- and 8-year-olds. Children recalled, knew, and preferred same sex items significantly more than opposite sex items. Results are compared with a previous study with English children. (ST)

This study was undertaken to determine whether neo-Piagetian theory might provide a functional interpretation of children's motor development, particularly linear positioning. In addition, intra-age and inter-age comparisons for both high- and low-mental-processing children were made. Pascual-Leone's Figural Intersection Test was used to select 15…

This paper describes a delayed response experiment which tested children's memory for the location of a hidden object. Eight boys and eight girls at each of two age levels (25 and 37 months) were assigned to each of four experimental conditions and given eight trials in a 9-choice task. On each trial the child saw the object hidden in one of nine…

The present study was designed to explore age differences in the association of temperatures with specific colors, using as stimuli actual felt temperatures rather than the 'imagined' or ambient temperatures used in other studies. (Author)

An investigation of the phenomenon of "word-realism" through an analysis of first-, third- and fifth-grade children's modes of reconstructing a story. The hypothesis is that a child would become more ego involved in a story which used his name rather than other familiar or unfamiliar names was supported. (ED)

Examined the effects of two levels of causality (intentional-accidental), outcome quality (good-bad), and affected object (human being-physical object) on the evaluations of acts and actors and the related response latencies. Four age groups of 128 children (5-11 years) were studied, using eight stories and two 4-point scales of good-bad and…

The study investigated motivation factors in 368 students in grades 4 through 9, including 180 students identified as academically gifted. Ss were administered the Junior Index of Motivation (JIM Scale) which measures six motivational factors: positive-negative school attitude, belongingness-alienation, idealism-pragmatism, personal…
