Handedness in native Amazonians
Handedness in native Amazonians is a scholarly work, published in 1993 in ''Neuropsychologia''. The main subjects of the publication include evolutionary psychology, social psychology, lateralization of brain function, reinforcement, sample, laterality, theory of mind, psychology, preference, developmental psychology, and handedness. These data indicate that positive reinforcement for right-hand use can modify patterns of handedness, and may well alter the relations among different items.
