Abstract
A rational classification of terms related to the sense of touch by means of semantic differential was carried out. Consequently, we could plot a few psychophysical functions in graphic forms.
Next, the correlations between psychological and physical scales were calculated and factor analyzed. The first factor has high loadings on scales, especially in not elastic, hard, stiff, sharp, painful, cold, not plastic, heavy etc. The second factor has high loadings on scales, especially in wet, smooth etc. The amount of variance accounted by first two factors amounted to 71%. Therefore, surface touch seems to be relatively simple.
