Four groups of children (N=80; C.A. 6.6. to 12.5; M.A. 7.9 to 14.7) were tested for ability to reproduce five-element two- and three-dimensional patterns. Significant interaction and main effects were found. Three-dimensional pattern performance increased with age; all ages performed well on two-dimensional patterns. (Author/DB)

Examines the development of young children's analysis of spatial patterns--specifically, hierarchical letter and geometric forms. Suggests that although children as young as four years of age demonstrated substantial analytic competence, their ability to integrate the parts of the spatial array to form a coherent whole was weaker and more easily…

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

Children and adults performed a divided attention task and two selective attention tasks with shapes that were either spatially integrated or separated. Results indicate that integrated stimuli are initially perceived as wholes, and separated stimuli as features, at all ages. (BC)

Two experiments used Visual Expectations Procedure to investigate development of expectations in infants up to 12 months old. Reaction time improved and the percentage of anticipations increased between 6 and 9 months using an alternation pattern or a complex pivot pattern, and between 4 and 8 months when using a left-right alternation or a…

Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)

The development of the "inversion" effect in face processing was examined in infants 3 to 6 months of age by testing their integration of the internal and external features of upright and inverted faces using a variation of the "switch" visual habituation paradigm. When combined with previous findings showing that 7-month-olds use integrative…

A developmental study investigated the pictorial and linguistic main idea identification skills of 104 students in second, fifth, and eighth grades. In the pictorial task, the subjects studied a complete picture story and ranked the effectiveness of four separate main idea alternatives at capturing the meaning of the story. Following the same…

The interpersonal visual behavior of subjects of various ages was studied as they (1) conversed, and (2) participated in a block construction task with a partner of the same sex and same age. (DP)

Results of two experiments minimizing verbal encoding and response demands indicate that when the ceiling effects in no-mask target recognition are removed, the visual information processing rates for children and adults can be considered equivalent. (Author/RH)

Two experiments were conducted to study the development of mental rotation abilities in late childhood, adolescence, and adulthood. Subjects were third, fourth, and sixth graders, and college students. (MP)

Examines the development of grapheme-phoneme conversion ability in normal and reading-age matched dyslexic readers. Thirty-six normal readers (mean age 9.5 years) and 18 children diagnosed dyslexic (mean age 12.1 years) served as subjects. (MP)

Two experiments examined the development of children's memory for spatial location or color. Results refuted the proposal that in contrast to color, spatial location would not show developmental improvement because it is remembered automatically. Suggests that, for the age range studied, there was developmental change in the efficiency of…
