Ninety-three pregnant women were recruited to assess fetal learning and memory, based on habituation to repeated vibroacoustic stimulation of fetuses of 30-38 weeks gestational age (GA). Each habituation test was repeated 10 min later to estimate the fetal short-term memory. For Groups 30-36, both measurements were replicated in a second session at 38 weeks GA for the assessment of fetal long-term memory. Within the time frame considered, fetal learning appeared GA independent. Furthermore, fetuses were observed to have a short-term (10-min) memory from at least 30 weeks GA onward, which also appeared independent of fetal age. In addition, results indicated that 34-week-old fetuses are able to store information and retrieve it 4 weeks later.
93名孕妇参与了一项评估胎儿学习和记忆能力的研究，该研究基于对30至38周胎龄（GA）胎儿重复进行的振动声学刺激的习惯化来进行。每次习惯化测试在10分钟后重复进行，以评估胎儿的短期记忆。对于30至36周组，这两项测量在38周胎龄时在第二次测试中重复进行，以评估胎儿的长期记忆。在所考虑的时间范围内，胎儿学习似乎与胎龄无关。此外，观察到胎儿从至少30周胎龄起就有短期（10分钟）记忆，这似乎也与胎儿年龄无关。此外，结果表明，34周龄的胎儿能够存储信息并在4周后提取这些信息。
