Intermodal organization: a methodological localization study.
The nature of organization among vision, right hand, and left hand was studied. A target was presented to one of the three modalities, and a response was required by one of the other two modalities. Constant errors from the resulting six conditions were examined to determine whether the three modalities function as an organized system, such that the relation between two modalities may be predicted from the relations of each of the two with the third. Predictions were correct in direction but incorrect in magnitude. The data also were analyzed to bear on the usually implicit assumption in research on localization that a response modality has consistent error characteristics regardless of the nature of the target being localized. It was concluded that such assumptions may not be valid.
