Inter- and intra-modal processing of sensory-specific stimuli.

Inter- and intra-modal processing was compared with modality-specific forms in two experiments on a group of 40 university students. In Exp. I, the RTs for tactual-to-visual and visual-to-visual processing were compared for 20 subjects, and in Exp. II, the visual-to-tactual and the tactual-to-tactual processing were compared for another group of 20 subjects. Analysis showed that intra-modal processing is faster than inter-modal processing. Further, the "same" RT is faster than the "different" RT. The inter- and intra-modal processing differences are based on the delay in retrieval and recognition across sensory-specific areas.
