Based on their scores on the Child Abuse Potential (CAP) Inventory, 30 nonparent adults were classified as either having high CAP scores (n = 15) or low CAP scores (n = 15). Subjects' heart rate and skin conductance were assessed as they listened to audio-taped presentations of four "normal" phonated infant cries and four high-pitched, hyperphonated infant cries. Subjects also rated the cries on several perceptual items. Results showed that both groups of subjects found hyperphonated cries more aversive, distressing, urgent, arousing, and sick than phonated cry sounds. Similarly, all listeners' showed higher skin conductance levels (SCL) in response to hyperphonated than phonated cries. SCL became attenuated over time in response to phonated, but not hyperphonated, cries. Adults in the high-CAP group, showed marginally higher heart rates than low-CAP adults following presentation of all infant cry sounds and responded to phonated cries with marginally higher skin conductance levels than low-CAP adults. The responses of high-CAP nonparent adults are similar to those of parents with histories of physically abusive interactions with their infants.
根据30名非父母成年人在虐待儿童可能性（CAP）量表上的得分，他们被分为CAP得分高的一组（n = 15）和CAP得分低的一组（n = 15）。在他们收听四段“正常”发声的婴儿哭声和四段高音调、高分贝的婴儿哭声的录音时，对他们的心率和皮肤电传导进行了评估。受试者还对这些哭声在几个感知项目上进行了评分。结果显示，两组受试者都认为高分贝哭声比发声哭声更令人厌恶、痛苦、急迫、激动和病态。同样，所有听众对高分贝哭声的皮肤电传导水平（SCL）都高于发声哭声。随着时间的推移，对发声哭声的SCL会减弱，但对高分贝哭声则不会。在播放所有婴儿哭声后，高CAP组的成年人心率略高于低CAP组的成年人，并且对发声哭声的皮肤电传导水平也略高于低CAP组的成年人。高CAP非父母成年人的反应与有虐待婴儿身体互动史的父母相似。
