In this study, we divided 26 fetuses at 32-37 weeks of gestation into three groups using combined criteria of gestational age and behavioral indicators. We investigated fetal habituation to vibroacoustic stimulation (VAS). Fetuses showed habituation from at least 32 weeks of gestation. Furthermore, fetuses less developed from behavioral standpoint took significantly more trials to achieve habituation than developed fetuses even in the same gestational age. Taken together with these data, it was proved that there was a relationship between aspects of behavioral development and habituation.
在本研究中，我们根据胎龄和行为指标的综合标准，将26例孕32 - 37周的胎儿分为三组。我们研究了胎儿对声振刺激（VAS）的习惯化情况。胎儿从至少孕32周起就表现出习惯化。此外，从行为角度发育较差的胎儿即使与发育较好的胎儿处于相同胎龄，达到习惯化也需要显著更多的试验次数。综合这些数据，证明了行为发育方面与习惯化之间存在关联。
