Abstract
Nonretarded and mildly retarded people were compared on an 8-choice reaction-time (RT) task. Removing a midline that divided the stimulus display in halves slowed RT of retarded subjects [Ss] to stimuli adjacent to the line. In the absence of this line, retarded Ss were also more dependent upon the position of the preceding stimulus and response.
