Mitempfindung in synaesthetes: co-incidence or meaningful association?
Mitempfindung is the referral of a tactile sensation to a location far away from the stimulation site. This brief note reports a 40% incidence of Mitempfindung in a sample of 20 digit-color synaesthetes which contrasts with a 10% incidence in two control groups of non-synaesthetes. Phenomenological similarities between Mitempfindung and synaesthesia are discussed, and we propose that an erratic neural connectivity underlies both phenomena. To better characterize the nature of the purported neurophysiological peculiarities, prospective studies are needed that characterize Mitempfindung in synaesthetes and nonsynaesthetes.
