The Origins of Concept Formation: Object Sorting and Object Preference in Early Infancy.
Studies of concept formation in infancy have demonstrated that certain experimental settings can elicit spontaneous behavior from infants which has been called "sorting" or "object grouping". This study pursues the issue of early sorting with infants as young as 6 months, and with a broader range of stimuli than has been used previously. Forty-eight infants, eight male and eight female at 6, 9 and 12 months were presented with eight sets of small, manipulable objects. Each stimulus set consisted of two groups of four objects each, the groups differing in size, color, form or some combination of these dimensions. Stimuli thought to be of high salience were included. Variables coded were: which object touched first; the order in which objects were touched; grouping together of objects. At both 9 and 12 months, infants showed a high level of sorting activity. At 9 months, 94% showed sequential touching of like objects, while 100% did so at 12 months. At 9 months, 13% and at 12 months 44%, demonstrated at least primitive object grouping. At 6 months, selective manipulation was conspicuously absent, leading to the conclusion that this activity must emerge sometime between 6 and 9 months. (Author/RH)
