Almost all locomotor animals are sensitive to optical expansion (visual looming) and for most animals this sensitivity is evident very early in their development. In humans there is evidence that responses to looming stimuli begin in the first 6 weeks of life, but here we demonstrate that as children become independent their perceptual acuity…

Recent work with human infants and toddlers suggests a dissociation between performance on looking and reaching tasks. Specifically, infants appear to generate accurate representations of occluded objects and their actions when tested in expectancy violation looking tasks but often fail to use this information when reaching for occluded objects.…

The visual and motor responses to novel and familiar stimuli were measured in twelve 6-month-old infants, using new measures of integration and concordance. Results indicate that the infants' responses to the stimuli were both integrated and concordant. (Author/JMB)

In this longitudinal study, infants' visual guidance of hand orientation was investigated by presenting a rod either horizontally or vertically to see if the orientation of the reaching hand was adjusted toward the orientation of the rod before contacting it. Subjects were l8 infants seen monthly between 18 and 34 weeks of age. (RH)

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)

Recent work on the development of the perceptual information-seeking function of the hand in relation to its motor-executive function is reviewed. (PCB)

Investigated shifts of gaze to peripheral targets in full-term and very preterm infants with transient periventricular echogenicity, a type of short-term brain damage, between 6-26 weeks old. Found that differences between full- and preterm infants was small, but after 16 weeks, there were subtle differences between them as preterms took longer to…

This paper discusses a longitudinal, exploratory study of developmental dimensions related to object permanence theory and explains how multidimensional scaling techniques can be used to identify developmental dimensions. Eighty infants, randomly assigned to one of four experimental groups and one of four counterbalanced orders of stimuli, were…

THE PURPOSE OF THIS STUDY WAS TO FIND OUT IF INFANTS WOULD EXHIBIT BEHAVIORS CONSISTENT WITH PIAGET'S OBSERVATIONS ON THE DEVELOPMENT OF RECIPROCAL COORDINATIONS AMONG THE LOOKING, SUCKING AND GRASPING SCHEMAS. A SECOND PURPOSE WAS TO SEE IF INCREASED LOOKING AT AND TOUCHING OF NEARBY OBJECTS BY INFANTS WOULD RESULT IN ACCELERATION OF THE…

The purpose of this paper is to illustrate the parents' role in their child's visual guidance program, the philosophies behind the program, and the teacher's responsibility to child vision. The first chapter, on parent involvement, instructs them to provide an environment to stimulate intellectual growth and stresses the importance of the…
