Data from an experiment on recognition of tactually presented upper case letters was used to make a confusion matrix like that made by G. C. Gilmore et al (1979) with visually presented letters. The significant product-moment correlation (.88) between the 2 matrices suggests that similar processes are involved in the 2 modalities and that visual models should not rely too heavily on uniquely visual mechanisms.
