INFORMATION COMPLEXITY AND CROSS-MODAL FUNCTIONS

Authors


Abstract

Intra-modal and cross-modal presentations of a matching procedure were compared at two levels of information complexity in the same subjects. The modalities were visual and somato-sensory. Sequence of information type and sex of experimenter and subject were systematically controlled. Pattern of accuracy among the several modality combinations and the effect of sequence varied as a function of information complexity. Sex of experimenter and subject yielded significant differences with simple information but not complex. The results, involving several detailed comparisons, confirmed generalizations derived from a review of prior studies in which only one type of information had been administered to any single group of subjects. Further examination of the relations between type of information and sensory modality is discussed.
