Experiment 1: Gender influence on auditory memory performance of rhesus monkeys. Auditory memory performance for match (A) and nonmatch trials (B) differs by gender. The graphs show average memory performance across seven sound types at fixed 5-second delays during match and nonmatch trials. Grey and black bars represent memory performance of female and male monkeys respectively. The asterisk indicated a significant performance difference between genders (A: repeated-measures ANOVAs, P < 0.05; B: linear regression analysis, P < 0.005). Males were always better than females in general. Abbreviations: monkey vocalizations (Mvoc), human vocalizations (Hvoc), animal vocalizations (Anivoc), music clips (Music), sounds of natural phenomena (Nature), synthesized clips (Syn) and band-passed white noises (WhiteN).
