一项纵向研究测量了一组IS孕妇在四种情况下（孕中期，孕晚期，产后6周和产后一年）的言语记忆测试，分散注意力和集中注意力的表现，同时获得这些认知功能的自我评估评级。一组14名未怀孕的妇女在相同的时间间隔进行了研究。两组女性在客观测试中的表现没有差异，随着时间的推移，除了从第一次到最后一次测试时注意力集中的程度有所改善外，表现也没有变化。然而，自我评估评级显示，在第二个三个月，孕妇认为自己比以前更受损与非孕妇的所有三个认知能力。确保：这种差异不是由于当前认知能力与先前认知能力比较的回顾性性质，第二个纵向研究比较了25名孕妇和10名非孕妇，在怀孕期间和产后第一年的四个场合，在一周的时间内使用每日评级。与未怀孕的女性相比，怀孕后期的女性在集中注意力和分散注意力的能力以及记住所读内容的能力方面存在轻度障碍。结果表明，有知觉的认知障碍在怀孕期间。有人建议，这些可能是由于轻微的障碍，没有显示在客观的测试，因为他们可以克服有意识的努力，在短期内的测试。或者，这种感觉可能不是基于实际的损害，而是由于抑郁情绪或对怀孕对认知影响的期望。
A longitudinal study measured the performance of a group of IS pregnant women on tests of verbal memory, divided attention, and focused attention on four occasions (second trimester, third trimester, 6 weeks post-partum, and I year post-partum) while at the same time obtaining self-assessment ratings of these cognitive functions. A group of 14 non-pregnant women was studied at equivalent intervals. The two groups of women did not differ in performance on the objective tests, and there was no change in performance over time except for an improvement in the measure of focused attention from the first to the final testing occasion. However, the self-assessment ratings showed that in the second trimester, the pregnant women rated themselves as more impaired than before compared with the non-pregnant women for all three cognitive abilities. To ensure that: this difference was not due to the retrospective nature of the comparison of current with previous cognitive ability, a second longitudinal study compared 25 pregnant and 10 non-pregnant women using daily ratings over a period of I week on four occasions during pregnancy and the first year post-partum. Women in the third trimester of pregnancy reported mild impairments in their focused and divided attention ability and their ability to remember what they had read compared with the non-pregnant women. The results show that there are perceived cognitive impairments during pregnancy. It is suggested that these may be the result of mild impairments which are not revealed in objective tests because they can be overcome by conscious effort in short periods of testing. Alternatively, the perceptions may not be based on actual impairments but may result from depressed mood or expectations concerning the effect of pregnancy on cognition.
