Successive visual discrimination of forms in 10-month-old infants.
The purpose of this research was to assess the infant's ability to make successive discriminations in the size of a figure. The Ss were 90 10-month-old infants who were habituated to a block figure and dishabituated on different subtle size transformations of that figure. Dishabituation data revealed that the infants were able to detect transformations which increased the area of the habituated figure by 7 percent. There was no evidence of a differentiated sensitivity to detect a change in any special location of the original figure.
