Active touch, passive touch with a moving object, and passive touch with a still object were examined developmentally with 192 subjects in first, third, and fifth grades and college. (Author/JMB)

Reports two studies of infant exploration. In the first, age and characteristics of the object stimuli influenced 6-, 9- and 12-month-olds who manipulated a series of objects. Results of the second study suggested that different kinds of manipulation are used to explore changes in shape, texture, and weight. (Author/CB)

Although a considerable amount is known about the development of object manipulation during the 1st year, less is known about how infants manually explore surfaces and relate objects to surfaces. To address these issues, 60 infants (20 each at 6, 8, and 10 months of age) were presented hard and soft objects on tabletop surfaces, which varied in…

This paper examines the developmental stages of haptic perception (the process of recognizing objects by the sense of touch alone), and attempts to clarify some conflicting results of studies of the effects of memory and object type. The paper also presents a specific study of haptic perception in 144 preschool and kindergarten children from…
