采用视觉配对比较模式，纵向探讨了饮食必需脂肪酸对幼龄恒河猴视觉注意的影响。在第2周、第5周、第9周和第13至9周，研究人员展示了灵长类动物的面部和图案，这些婴儿缺乏omega-3脂肪酸，第8周喂食标准的托儿所饮食。在同时呈现两种刺激之前，先熟悉每对中的一个成员。饮食不足的婴儿在即时和24小时的测试中都显示出更长的个体长相。对于熟悉的刺激物，注视的持续时间随着年龄的增长而减少，而对于新的刺激物则没有。观察新刺激的时间比例（% novel）随着年龄的增长而增加，但不受饮食的影响。观察持续时间和新鲜度受到不同的影响，可能反映了不同的潜在过程。
Effects of dietary essential fatty acids on visual attention were explored longitudinally in infant rhesus monkeys with a visual paired-comparison paradigm. Sets of primate faces and of patterns were presented at Weeks 2, 5, 9, and 13 to 9 infants deficient in omega-3 fatty acids and 8 fed a standard nursery diet. Familiarization to 1 member of each pair preceded simultaneous presentation of both stimuli. Infants fed the deficient diet showed longer individual looks in both immediate and 24-hr tests. Duration of looks decreased with age to familiar but not to novel stimuli. The proportion of time looking at the novel stimulus (% novel) increased with age but was not affected by diet. Look duration and % novel were differentially affected and may reflect different underlying processes.
