Two hundred and twenty two children (104 females), 1-8 years of age and young adults, were tested for up to 25 days on five versions of a non-verbal, non-navigational landmark task that had previously been used for monkeys. In monkeys, performance on this task is severely impaired following damage to the parietal cortex. For the basic task, the…

Theory suggests that the vision-for-perception and vision-for-action processing streams operate under very different temporal constraints (Glover, 2004; Goodale, Jackobson, & Keillor, 1994; Graham, Bradshaw, & Davis, 1998; Hu, Eagleson, & Goodale, 1999). With the present study, children and young adults were asked to estimate how far a cued target…

Children and adults normally interpret the spatial expressions "in front of" and "behind" in a nondeictic way when fronted objects are used. Two experiments involving a treasure hunt game investigated subjects' (6 to 10 years and adults) awareness of an alternative, deictic interpretation. (Author/BE)

Bengali, English, and Hindi-speaking children five to nine years old were asked to place an object in front of or behind objects with or without obvious fronts. All children responded on the basis of an inherent object cue when a fronted object was used. When a nonfronted object was used, all children treated it as a fronted object. (Author/MP)

Two studies investigated the effect of age on memory for visual and spatial information. Five to 10 year olds were asked to reconstruct a previously seen spatial arrangement of objects. The association between an object's identity and its location was weaker for younger than for older children. (LB)

Investigates the ability of Malawians ranging from 7 through 23 years of age to make judgements of the relative sizes and spatial locations of objects in photographic scenes with restricted cues to depth. All age groups responded with an accuracy significantly above chance. Exhibiting maximum scores, adults were significantly more accurate than…

Children and adults were asked to place something "in front of" or "behind" a featured or nonfeatured object. Most subjects responded to the object's inherent features. A significant number of adults used the observer orientation cue. Children had more difficulty with the nonfeatured object but also used the observer…

Attempts the theoretical rapprochement of two theoretical constructs on working memory, neo-Piagetian models and Baddeley's model. Summarizes both types of models, then discusses their similarities and differences. Presents the results of a longitudinal study that supported the idea that these models might be complementary rather than…

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)
