Suggests that differential rearing conditions may cause significant reversals in sex-related ability and behavior (maze learning and exploration), and may significantly affect perceptual sensitivity. (RL)

The ability of young infants between the ages of 8 and 17 weeks to perceive outline shapes was investigated in nine experiments using an habituation paradigm. (JMB)

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 the nature of spatial representations underlying simple visually guided actions with 3- and 7-month-old infants. Saccades in older infants were executed within body-centered spatial coordinates that account for intervening eye movements, whereas younger infants responded according to the target's retinocentric locations without…

A visual oddball paradigm was used to investigate whether children with high functioning autism had difficulty detecting mutual gaze under experimental conditions. Findings revealed that children with autism were no better at detecting direct gaze than at detecting averted gaze, unlike normal children. Findings suggest that the lack of ability to…

Investigated the relative effects of developmental level and domain-specific knowledge on 4- to 9-year-olds' ability to identify and make similarity decisions about objects based on haptic or tactile information. Found that older children explored models more exhaustively, found more differentiating features, and made fewer errors than younger…

To understand why children perceive traffic differently from adults, adults must position themselves at children's level, physically and cognitively, and devise instructional techniques that reflect children's size and physical and cognitive development. (IAH)

Data from this study of skilled and unskilled badminton players aged 10 to adult indicated the presence of systematic differences which transcend developmental age between the perceptual skills of expert and novice players. (JD)

An intermodal preference task, which presents 2 events side-by-side with a single sound track appropriate to 1 event, and measures subjects' visual preferences, was presented to 23 children with autism. Subjects showed the intermodal matching effect demonstrated with normal infants and young children; subjects did not demonstrate primary…

A study with three- and five-year olds contrasted two important proposals regarding children's assumptions about word meanings: the taxonomic assumption proposal and the shape bias proposal. Results suggest that perceptual similarity, particularly shape similarity, is very important in early word meaning but that children gradually shift their…

Examined children's social comparisons in conversational stories of past personal experiences as they related to development of concept of self. Found that comparisons of self with others increased with age. The 2-1/2-year olds used comparisons to convey similarities between self and others, whereas the 5-year-old subjects used social comparison…

Two experiments, involving a total of 126 subjects with mental retardation (mental age from 5-11 years), found that subjects were less likely than controls to employ the "difference rule" (communicate to the listener how a referent is different from other stimuli) and that perceptual feedback training enhances referential communication…

This paper offers a model of visual functioning focusing on three factors: (1) visual capacity, (2) visual processing, and (3) visual attention. Practical implications of visual therapy are considered, and intervention strategies with children with impaired visual functioning are suggested. (Author/DB)
