(2) To test experimentally an hypothesis derived from this theory. On the basis of the experimental literature it seems safe to assume that sensory stimulation applied to one modality can influence the response obtained in a second modality concurrently stimulated. Such heteromodal effects have been reported under a wide variety of experimental conditions, and indicate that both the facilitation and inhibition of a given sensory response are integral aspects of the inter-sensory process. In terms of these findings it seems a reasonable assumption that both the magnitude and direction of intersensory effects are closely related to the intensity level of accessory stimulation.[Truncated]en-USBased on investigation of the BU Libraries' staff, this work is free of known copyright restrictions.Thesis/Dissertation
