This study investigates children's metarepresentational competence (MRC) with regard to listening to and making sense of simple sonic stimuli. Using diSessa's (2002) seminal work on MRC in mathematics and sciences as background, it aims to assess the relative importance children attribute to several criteria for representational adequacy…

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…

Investigated the development of classificatory organization. Two experiments examined age differences in children's spontaneous extensions of a classification and a third examined children's extensions under hypothesis-testing instructions. (JMB)

Reports results of a study of the development of perspective-taking skills of 180 English children aged six through ten. Children first are able to represent the object nearest the observer, then before-behind relationships, and subsequently left-right relationships between objects. Questions Piagetian conclusions that perspective-taking ability…

This study used meaningful pictorial material to compare the functions relating complexity to two different response variables (voluntary looking time and preference) in 192 students from grades 1 to 8. Age differences were slight, and results are discussed in terms of theories postulating increases with experience in preference for complexity.…

Children ranging in age from three to six years counted 7, 10, and 14 items arranged in columns or in rows. Developmental changes in the spatial strategy and the relation of strategy to accuracy were examined. (JMB)

The Rorschach was given to 60 school children in two designs: chronological age (CA) and mental age (MA) orthogonal and CA=MA. Responses were scored for Form Accuracy, Complexity, Movement and Friedman's Developmental Level (DL) Scoring System. The results suggest that the DL system does assess MA independently of CA.

This study investigated the hypothesis that as children become older they are increasingly likely to make efficient use of accessible retrieval cues. Results confirmed the hypothesis. (ST)

In this experiment, 446 children, ranging in age from 5-10 years, were required to draw one object behind another in a situation in which adults invariably produce the further object partially occluded to the nearer. (MS)

Investigated two developmental implications: (1) that foci for color categories become established and stabilized earlier than boundaries, and (2) that focal judgments are always more stable than boundary judgments. Subjects were 20 kindergarteners, 40 third graders and 40 adults. (Author/SDH)

Three experiments examined the effects of selected factors of interval size, timbre, loudness, and length of the melodic pattern on children's ability to perceive, the motion of 2- and 3-pitch melodic patterns. Subjects for all experiments were 32 second- and 32 fifth-grade children. The task for each experiment consisted of identifying the motion…

Focused and divided auditory attention were studied in 7- and 10-year-old children. (BD)

The effects of perceptual and cognitive factors on information processing in visual periphery were studied in 5- and 8-year-old children and in adults. Subjects judged either the similarity (Study 1) or identity (Study 2) of geometric forms. (Author/SB)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)
