ABSTRACTAn experiment by Nathan and Rice (1966) on the localization of thermal sensations was replicated. The present, somewhat more detailed, results essentially confirm the findings of the earlier authors. Thermal sensations evoked by non‐tactile thermal stimuli can be localized; their localization is less accurate than that of tactile stimuli; and the accuracy of localization increases with increasing intensity of stimulation and sensation. To account for these findings several alternative hypotheses concerning the interaction between thermal and tactile modalities and large and small fiber sensory systems have been suggeste
