摘要: Abstract In two experiments, first- and fourth-grade subjects (age 6 9 years) performed a speeded card-sorting task with either integral or nonintegral dimensions. The dimensions were so arranged that sorted on three types of task: (1) single dimension, (2) correlated dimensions, (3) orthogonal Results the first experiment indicate both in manner not qualitatively different from adult ( Garner & Felfoldy, Cognitive Psychology , 1970 1 225–241). comparison single-dimension tasks, performance was facilitated correlated-dimensions tasks interference observed orthogonal-dimensions tasks. Performances revealed an age-related processing difference. Fourth graders like adult; no differences between contrast, first-graders as if they integral. Interference consistently On easy redundancy difficult second experiment, showed consistent facilitation task; all other results indentical to those Experiment I. interpreted perceptual learning theory Gibson, Principles development .
