[The effects of cue stimuli on the reaction times of mentally retarded children: an examination of the temporal factor and the spatial factor (author's transl)].
To investigate the covert behavior performed by retardates during the warning intervals of simple RT task, cue stimuli consisting of a combination of the mode of the temporal presentation (regular vs. irregular) and the mode of spatial presentation (regular vs. irregular), were introduced in the warning interval. Retarded and normal children performed under these conditions. For retardates the spatial regularity was more effective than the temporal regularity. For normals there was little RT difference among the four experimental conditions. Retardates had minimized RT under the condition in which the cue stimuli were presented regularly in the spatial order. These results suggested the difference in the covert behavior performed by retardates and normals.
