Videotapes were made of the prehensile activity and looking behavior of 2- and 5-month-old infants in the presence of objects placed within and beyond possible contact distance. (BRT)

Four experiments assessed converging aspects of four-month-old infants' perceptions of visual patterns. Results together corroborate and extend previous findings that vertical symmetry has a special status in early perceptual development and that infants can perceive pattern wholes. (Author/AS)

After learning to discriminate tactually between a convexity and a concavity, 101 children aged three to eight years were presented a photograph of the convexity and the concavity. The relevance of egocentric, environmental, and lighting-specified frames of reference was manipulated by changing the position of the subject's head, rotating the…

Habituated 180 neonates to white lights of varying luminance and tested for recovery of habituation to green, yellow, or red lights varying in excitation purity. Found that newborns discriminated chromatic stimuli from white only when excitation purity exceeded levels much higher than those for adults. Results reinforce view that neonates' vision…

Analysis of 40 first-grade children's performance on two discrimination learning problems revealed that children do transfer dimensional information between the visual and tactual modalities. (Author/JMB)

Discovering a child's possible auditory and visual perceptual problems at the reading readiness stage may save him years of frustration in reading. (MM)
