Results indicate that kindergarten and first-grade pupils who were trained in visual perception scored no higher than their controls on the academic or readiness tests. Therefore, the use of this program as a supplement to traditional readiness activities does not appear to be warranted. (Author)

Contrary to Piaget's predictions, adolescent retardates and 9-year-old normals were more susceptible to the Oppel-Kundt Illusion than high school sophomores and adults. No group differences were found on the Poggendorf Illusion. (MH)

Responses of 241 convicts on 18 primary mental abilities were factored to explore the idea that there are organizations among visual and auditory functions that operate independently from the relation-perceiving and correlate-educing functions of fluid and crystallized intelligence. The suggested reliable common-factor functions are discussed.…

Analyzes third grade children's performance on the Mueller-Lyer Illusion for whole and partial presentations of the figure. Results do not support Piaget's theory of perceptual development but are consistent with the theory of simultaneous and successive syntheses. (Author/BH)

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…

A recognition-based paradigm was used to investigate possibility that past research failed to sensitively assess infants' perception of the unity of misaligned edges in partial occlusion displays. Results suggested that habituation designs tapping recognition processes may be particularly efficacious in revealing infants' perceptual organization.…

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…
