The effect of complex visual reinforcement (animated toy animal) on auditory localization responses of infants below 12 months of age was studied. Sixty infants served as subjects and each subject received 30 presentations of complex noise at suprathreshold level. After each response to an auditory signal, one-half of the infants (experimental group) received complex visual reinforcement and the other half (control group) received no reinforcement. The experimental and control groups were further subdivided into three age groups: four months, five and six months, and seven to 11 months. Visual reinforcement produced significantly more responses (head turn) than no reinforcement for the two older age groups. There was no significant difference between the experimental and control conditions at four months of age.
研究了复杂视觉强化（动画玩具动物）对12个月以下婴儿听觉定位反应的影响。60名婴儿作为受试者，每个受试者接受30次阈上水平的复杂噪声刺激。对听觉信号的每次反应后，一半婴儿（实验组）接受复杂视觉强化，另一半（对照组）不接受强化。实验组和对照组进一步细分为三个年龄组：4个月、5和6个月、7至11个月。对于两个较大年龄组，视觉强化产生的反应（转头）明显多于无强化组。4个月大时，实验组和对照组之间没有显著差异。
