Right Hand Preference and Performance Biases in the Foraging Behavior of the Aye-Aye

Abstract

Research on handedness in primates has revealed a leftward bias for prosimians (Forsythe, Milliken, Stafford, & Ward, 1988; Forsythe & Ward, 1988; Milliken, Forsythe, & Ward, 1989; Milliken, Stafford, Dodson, Pinger, & Ward, 1991; Sanford, Guin, & Ward, 1984; Stafford, Milliken, & Ward, 1993; Subramoniam, 1957; Ward, Milliken, Dodson, Stafford, & Wallace, 1990) and a rightward bias for anthropoid species (Bresard & Bresson, 1983; Beck & Barton, 1972; Deuel & Dunlop, 1980). The leftward preference seen in prosimians is related to the basic prehensile type of manual control whereby all fingers move in concert, and the right preference of anthropoids reflects a refinement in manual function that involves independent control of each finger.
