Answer

Yes. Two touches are felt separately if they extend across independent receptive fields

Work Step by Step

A receptive field is a space or area where impinging stimuli will affect the firing of the neurons in that area. The receptors in the skin-- Merkel's discs, Pacinian corpuscles, and Ruffini nerve endings are distributed over more or less circumscribed spaces or receptive fields. Visual receptors also have receptive fields. and visual stimuli have receptive fields. If a touch stimulus crosses boundaries otwo or more receptive fields, it will be felt as two or more separate touches.
