Intersensory facilitation of learning sets in normal and brain operated monkeys.

Abstract

"Eight monkeys, four with posterior parietal lesions, were given 75 visual and 75 tactual 12-trial object discriminations. Half of each group received the visual problems first and half the tactual series first. Previous tactual experience facilitated visual learning-set formation in the normals, even though little or no tactual learning was apparent. Parietals were deficient in visual learning-set formation and showed no facilitation from prior tactual experience. Parietals also exhibited less strong tactual preferences than the controls."
