"Mommy brain" is a long-held perception that mothers are more forgetful and less attentive.

"In most studies, however, attention and memory tests are given to mothers very early postpartum," said Valerie Tucker Miller, a Ph.D. student in Purdue University's Department of Anthropology department. Miller is studying the effects of motherhood on attention, memory and other psychological processes.

"There are few issues with that," she added. "When you first have a child, you have a cascade of hormones and sleep deprivation that might be affecting attention and memory processes in the brain."

In a new study testing the prevalence of "mommy brain," Miller used a revised version of the Attention Network Test (ANT), called the ANT-R, to compare reaction times among 60 mothers, all of whom were at least one year postpartum, and 70 non-mothers. The results, published online in the journal Current Psychology, show that mothers performed equally as well or better compared with women who had never been pregnant or had children.
在一项测试“妈咪脑”普遍程度的新研究中,米勒使用了改进后的注意力网络测试(ANT)—— ANT-R,对60名母亲(均处于产后一年以上)和70名非母亲的反应时间进行比较。发表在网络版美国《当代心理学》的研究结果显示,与从未怀孕或从未生育的女性相比,妈妈们表现得同样出色甚至更好。

"For this particular study, we recruited moms who were past that first year postpartum because we wanted to see the long-term effects of maternity," she said. "Overall, moms did not have significantly different attention than non-mothers, so we did not find evidence to support 'mommy brain' as our culture understands it. It's possible, if anything, that maternity is related to improved, rather than diminished, attentiveness."

Co-author Amanda Veile, an assistant professor of anthropology at Purdue, said the mixed-method study may be the first to investigate the long-term effects of biological motherhood on real-life attention network functioning. Lisa A. VanWormer, a Purdue University alumna and visiting associate professor of psychology at St. Norbert College, also is a co-author.

Researchers used a seven-point scale to measure participants' responses to survey questions such as, "How sleepy do you feel?" and "How do you think your attentiveness is?" Women's perceived attention functioning was strongly associated with their tested attention scores, regardless of motherhood status, Veile said.

"This means that women have accurate awareness of their cognitive state, and that their concerns regarding their perceived attention functioning should be taken seriously," she said. "We also believe that 'mommy-brain' may be a culture-bound phenomenon, and that mothers will feel the most distracted and forgetful when they feel stressed, overextended and unsupported. Unfortunately, many U.S. moms feel this way, especially now in the midst of economic and political instability and pandemic."
