The Memorability and Discriminability of
Primitive Perceptual Units in Infancy
SCOTT A. ADLER,* CAROLYN ROVEE-COLLIER*?
Received 29 January 1993; in revised form 15 July 1993
Three-month-olds were operantly trained to kick to move a block mobile that displayed a horizontal
and a vertical line (`ctextons") arranged as L, T, or + on each side. Delayed recognition was tested
either 0, 1, 3, 5, 7, or 9 days later with either the same or a different display. Infants failed to
discriminate between Ls and Ts after delays longer than 1 hr but discriminated both from +s, which
contains an additional texton (the line crossing), after delays as long as 7 days but not 9. Also, they
remembered +s longer than L.sand Ts. These data indicate that the same primitive perceptual units
that mediate adult texture segregation are differentially discriminated and differentially memorable
in early infancy.
