Infant rhesus monkeys were (a) fed a diet high in phenylalanine or (b) fed a diet high in p-chlorophenylalanine for the 1st 12 months of life, (c) selected from mothers fed a diet high in phenylalanine during pregnancy, (d) fed a diet low in phenylalanine, (e) maintained as controls, or (f) maintained as pair-fed controls. Tested during the 1st year of life with familiar peers, during the 2nd year with unfamiliar stimulus animals and with a movie film, the 3 groups of phenylketonuric monkeys showed less play and other positive social behavior and more withdrawal and more aggressive behavior than did the 2 control groups. The results support learning data suggesting that phenylketonuric monkeys are more emotionally reactive.
(a) 在出生后的头12个月喂食高苯丙氨酸饮食；(b) 在出生后的头12个月喂食对氯苯丙氨酸含量高的饮食；(c) 选取孕期喂食高苯丙氨酸饮食的母猴所生的幼猴；(d) 喂食低苯丙氨酸饮食；(e) 作为对照组饲养；(f) 作为配对喂食对照组饲养。在幼猴1岁时与熟悉的同伴进行测试，2岁时与不熟悉的刺激动物及电影进行测试，结果显示，与两个对照组相比，三组苯丙酮尿症幼猴的玩耍及其他积极社交行为较少，退缩行为和攻击性行为较多。这些结果支持了相关研究数据，表明苯丙酮尿症幼猴的情绪反应更强。
