Explores the nature and consequences of developmental change in speed of information processing. Summarizes evidence indicating that age differences in processing speed reflect a global mechanism that limits processing speed on most tasks. Describes evidence that suggests a role for processing speed on the development of intelligence. (Author/MKA)

The comprehension of big, little, and same number and the production of relational terminology was assessed in 168 preschool children. (Author/BD)

Four types of semantic relation, assumed by different researchers to be implicated in the organization of semantic information, were investigated by means of false recognition and word association tasks presented to independent samples of 4- and 5-year-old children. (Author/SB)

This study was designed to determine whether infants could perceive action role reversals when the direction of action is ruled out as a cue; whether infants consider inanimate, nonpotent objects to be unlikely agents; and whether both these discriminations could be reliably reflected in the heart rate response. (Author/SB)

Five conference reports that originally appeared as monographs of the Society for Research in Child Development concern cognition in young children. Included in a section on thought are articles on Piaget and his theories, computer simulation on human thinking, and an information processing theory of intellectual development. The development of…

The development of children's comprehension of cause and effect relationships was studied in 68 kindergarten, first grade, and second grade children. (BRT)

This paper deals with the primary processes of cognition in fifth- and sixth-grade children; i.e., how children this age interpret what they see and hear, how they remember it, and how they reason and solve problems. Designed to provide background information for the staff of the Skills Essential to Learning Television Project (a multi-level…

The study examined whether an awareness that semantic organization is beneficial to picture recall ("semantic enhancement") precedes an awareness that certain types of organization are more beneficial than others ("levels of processing"). A series of pilot studies was conducted with kindergarten and adult subjects and a formal…

Presents a reply to and an analysis of a study which examined the use of logograph research to determine children's cognitive integration ability. The study in question had been based on the present author's previous research. (BD)

This study attempted to determine whether a combination of seriation and classification training would produce more general intellectual gains. (Author/SB)

In research conducted "over a period of 20 years" on aptitudes of high level personnel, the purpose was to analyze thinking abilities or processes into their unique components. The approach was through study of individual differences in performance on intellectual tasks varied systematically over broad ranges of psychological functioning.…

A series of five experiments was designed and administered to 679 elementary and junior high school students over a 2-year period to test the relevance of Jean Piaget's concept of conservation to musical learning. Musical tasks consisting of stimulus patterns and systematic variations of these patterns were designed for each experiment, and…
