123 newborn infants were tested for changes in arterial oxygen status as an index of response to three voices, one of these being the maternal voice. Male infants responded more than female infants to their mother's voice, but female infants showed a higher response to the other female voice and the male voice. Black infants of each sex responded more than white infants to the maternal voice and to the other female voice. White female infants responded more than black female infants to the male voice.
对123名新生儿进行了动脉血氧状态变化测试,以此作为对三种声音反应的指标,其中一种是母亲的声音。男婴对母亲声音的反应比女婴更强烈,但女婴对另一名女性声音和男性声音的反应更强。每种性别的黑人婴儿对母亲声音和另一名女性声音的反应都比白人婴儿更强烈。白人女婴对男性声音的反应比黑人女婴更强烈。
