Designed to determine the effects of multiple and linear imagery on performance of a visual location task, this study also considered whether scores on such a task were affected by the interaction of presentation mode (multiple and linear imagery) and perceptual type (haptic and visual). (Author/JEG)

Three experiments were performed using an aperture-viewing technique to assess the accuracy of shape perception when subjects were required to emit eye movements in order to pick up shape information, compared with the accuracy of shape perception when subjects were not required to emit eye movements. All three experiments explored whether the…

Examined children's and adults' perceptions of facial stimuli that were either systematically exaggerated (caricatures) or de-exaggerated (anticaricatures) relative to a norm face. Found that all ages perceived caricatures as the most distinctive version and anticaricatures as least distinctive; the smallest effect was for 6-year-olds. Caricatures…

Matching-to-sample skills are involved in language acquisition and reading and counting abilities. The rapid, even errorless, induction of matching performances in young children and 28 individuals with mental retardation (ages 11-20) was demonstrated through the structuring of a visual array that promoted detection of the relevant stimulus.…

Three experiments investigated discrimination and memory of 5.5-month-olds for videotapes of women performing different activities (blowing bubbles, brushing hair, brushing teeth) or static displays after a 1-minute and a 7-week delay. Findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5-month-olds. Findings…

Delineates how the transition from one element to another facilitates the identification of individual form and function. Explains the process of bridging separate forms and functions to give meaning to what is seen. (KEH)

Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

This study examined effects of visual impairment on the performance of typical educational tasks requiring visual accommodation to print material at three different distances. Subjects were 18 visually impaired and 19 nonimpaired children (ages 6-10). Findings indicated that visually impaired children exhibited more fixation shifts per task.…

Examined children's emotional and cognitive responses to emotionally evocative vignettes. Results indicated age-related increases in children's responses. Found limited increases with age in children's concordant emotions, or emotions identical to emotions of persons in the vignettes, and continuous increases with age in children's attributions…

Children and adults were more likely to claim a word was presented as a picture than vice versa. Results indicated the absence of developmental differences in reality monitoring and similarity in representational processes of children and adults. (BC)

A study involving elementary school students in three age groups examined two explanations for the finding that young children tend to classify objects according to similarity relations, whereas adults emphasize dimensional structure. Results countered the view that children perceive objects according to a more primitive holistic structure. (RH)

Describes the nineteenth-century parlor trick entitled the Fluttering Heart phenomenon which uses a red heart on a bright blue background. Discusses theories concerning the apparent fluttering. Suggests doing the trick with a red light-emitting diode in a darkened room. (MVL)

Three experiments examined 4- and 6-month-olds' sensitivity to the unity of a partly occluded moving rod undergoing translation, rotation, or oscillation. Findings suggested that all types of common motion were not equivalent for specifying infants' perceptions of occluded objects. (Author)

Three experiments examined the hypothesis that individual differences in look-duration during infancy covary with different modes of visual intake and encoding, with longer look-durations reflecting encoding based on prolonged inspection of local visual properties, and briefer durations reflecting encoding based on a global, or global-to-local…

The performance of eight adults with Asperger syndrome was compared with the performance of controls on a range of perceptual tasks designed to test two models of perceptual deficit: the central coherence deficit model and the hierarchization deficit model. Tentative support for the hierarchization deficit model was demonstrated. (Contains ten…
