Infant Memory for Primitive Perceptual Features.
Adler, Scott A.
Textons are elongated blobs of specific color, angular orientation, ends of lines, and crossings of line segments that are proposed to be the perceptual building blocks of the visual system. A study was conducted to explore the relative memorability of different types and arrangements of textons, exploring the time course for the discrimination and forgetting of textons for infants, and the relationship between the duration for which different textons are remembered and their differential discriminability for adults. Subjects for the experiment included 120 3-month-old infants, who were trained to kick to move one of three mobiles, each of which was composed of seven pink wooden blocks, on each side of which were displayed computer-generated, overlapping black lines arranged as either L, T, or +. Training sessions were followed by a delayed recognition test. Study findings included the following: (1) infants remember +'s (which are preattentively discriminated by adults) more than twice as long as L's or T's (which are not); (2) infants discriminate a change in a single texton type for as long as the original mobile can cue retrieval of the task; and (3) infants' discrimination of L's and T's from +'s is not the result of differences in the subjective sizes of these stimuli nor differences in characters' orientation or position.
