Abstract	Compared were performances of 12 educable mentally retarded (EMR) and 12 normal children in grade 6 on a perceptual learning task to determine whether individuals with different intelligence levels have different learning abilities. A protable minicomputer was used to present "old letters" (usual lower case letters) and "new letters" (letter-like figures consisting of vertical lines and shorter horizontal lines) on a screen alternately in 10 trial blocks during 21 days. The computer automatically calculated a student's response latency and errors for four conditions (successive and simultaneous old and new letters). Results of statistical analysis indicated no significant differences between the groups in their central processing of information on the four task conditions, and significantly higher latencies for the EMR group. Both groups improved with practice. The differences in attention, orientation to the stimulus response selection, and speed of motor activities were thought to account for the differences between normal and EMR retarded children. (MC)
