The effects of training on the ability to identify 4 infants' cry-signals (birth, hunger, pain, and pleasure) were studied in 60 college students (aged 18 to 30 yr.). Subjects with training scored significantly higher than those without in identifying all but the pleasure cry-signal. In a follow-up retest 10 wk. later, scores for the birth and hunger cry-signals improved significantly (p less than .05) for subjects without training, while scores for subjects with training remained about the same. The suggestion that repeated exposure to cry-signals may serve as training was discussed.
在60名大学生（年龄在18至30岁之间）中研究了训练对识别4种婴儿哭声信号（出生、饥饿、疼痛和愉悦）能力的影响。接受训练的受试者在识别除愉悦哭声信号之外的所有信号方面得分显著高于未接受训练的受试者。在10周后的后续重新测试中，未接受训练的受试者在出生和饥饿哭声信号方面的得分显著提高（p小于0.05），而接受训练的受试者得分基本保持不变。讨论了反复接触哭声信号可能起到训练作用这一观点。
