Abstract
Two samples of 10 random polygons were scaled tactually and visually using multidimensional scaling techniques. Unidimensional solutions were very similar for both modalities and were linearly dependent upon the number of independent sides of the forms. Solutions of higher dimensionality did not produce clearly interpretable unique orderings of the forms beyond the first dimension with these samples. Within the limits imposed by these samples of forms. the data strongly support equivalence for visual and tactual form perception.
