'Baby brain' doesn't exist, tests reveal
     2015-April-21  08:53    Shenzhen Daily

    While those who are pregnant may believe their memory is worse than usual, a study has found that they perform just as well as other women in mental tests. And it doesn't just apply to memory. Other key skills, including attention span and spatial awareness, are equally unaffected by pregnancy.

    With previous studies into the existence of baby brain providing mixed results, the team from Brigham Young University in Salt Lake City set out to come up with a definitive answer.

    They put 21 mothers-to-be through a battery of mental tests a few weeks before their baby was due and again a couple of months after the birth.

    Another 21 women who weren't pregnant and had never had any children also completed the three-hour set of tests.

    There were no differences between the two groups in memory, thinking, attention span, organizational or spatial skills.

    Whether the tests were taken during pregnancy or when looking after a young baby, the women did just as well as those who had never been pregnant.

    However, when asked how they had performed, the pregnant women and new mothers thought they had done worse. They also said they had a lower quality of life and were less satisfied with their lot.

    Psychology professor Michael Larson, lead author of the study, said, "I was surprised at how strong the feeling was that they weren't performing well."

    Writing in the Journal of Clinical and Experimental Neuropsychology, Professor Larson said that the expectation of baby brain may be so strong that a pregnant woman is extra-alert to memory lapses.

    So, although they happen no more than usual, she may notice them more and therefore think they do.

    A study from Yale University found that a woman's grey matter grows in the weeks and months after she gives birth.

    研究表明“孕傻”不存在

    尽管孕妇们觉得自己的记忆力变差了,但是一项研究发现,她们在脑力测试中的表现和没怀孕的女性一样好。

    而且不光是记忆力。其他重要技能,包括注意力和空间感,都没受怀孕的影响。

    由于先前对“孕傻”是否存在的研究,给予的答案模棱两可,来自美国盐湖城杨伯翰大学的团队对此展开研究,以给大家一个确切的答案。

    他们让21位准妈妈在预产期前几周参加了一系列脑力测试,在产后几个月,又对她们进行了一次测试。

    另外21位未怀孕且从未生育的女士同样完成了这些长达三小时的系列测试。

    结果显示:被测试的两组女性在记忆力、思维、注意力持续时间、组织技能或空间方位感上的表现并无差异。

    在测试中,妈妈们无论是在怀孕期间,还是在照顾宝宝期间,都表现得完全与未怀孕的女士一样好。

    然而,当被问及先前的表现时,准妈妈或新妈妈都会觉得自己做得更糟。她们还表示,她们的生活质量变差了,生活状况也不那么如意。

    作为此次研究的领头人,心理学教授迈克尔?拉尔森说:“她们对自己表现不好的感觉是如此强烈,这着实让我惊讶。”

    拉尔森教授在《临床和实验神经心理学》杂志上写道,孕妇对“孕傻”的预期那么强烈,以至于老觉得自己的记忆力在衰退。

    因此,尽管她们孕后与孕前的记忆力一样,她们也会对自己的孕后记忆力多加关注,结果就是,她们觉得自己“孕傻”了。

    另一项耶鲁大学的研究发现,女人在产后几周、几个月里大脑灰质增多了。
