Recognition of form by pre-school children after progressive visual exposure

The purpose of this study was to examine the factors that influence integration of shape information by pre-school children. In a series of four experiments, children saw shapes revealed behind a narrow aperture in an opaque screen and they were then tested for recognition of the shape, In the first experiment, 3-year-old children recognized the shapes presented behind a stationary aperture both with and without a delay of 10 seconds between exposure and test. In Experiments 2A, 2B, and 3 with 2.5-year-old children, it was found that shape recognition was facilitated by a moving aperture as opposed to a moving shape, by up-down as opposed to left-right exposure, and by immediate as opposed to delayed recognition after familiarization with the choice array. It was concluded that recognition of progressively exposed form by 3-year-olds is mediated by integrational and memorial processes that although not fully mature are capable of supporting sophisticated cognitive activities.
