荷兰科学家进行的一项新的研究发现在胎儿30周时胎儿具有短期记忆。

科学家对93名荷兰健康孕妇和30-38周的胎儿进行了研究，测量胎儿如何回应反复的振动刺激的变化。胎儿每十分钟接受一次振动刺激，根据胎儿对此刺激的反应来评估其短期记忆。他们发现胎儿至少在30周以后存在10分钟的短期记忆。第一阶段测试胎龄为30-36周的胎儿，在38周时进行了第二阶段的测试，来评估胎儿的长期记忆。他们发现34周大的胎儿能够存储信息四周并回忆起。34 和36周大的胎儿习惯的速度远远超过了38周大尚未测试之前的胎儿。这意味着这些胎儿具有至少4个星期的记忆， 这个间隔存在于34周和38周试验之间。

这项研究对胎儿发育提供了深入了解，并可能帮助解决和防止异常。它是由在马斯特里赫特大学医学中心和St. Radboud大学医学中心的研究人员发表在2009年7月/8月儿童发育期刊上。

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.
