New Study Highlights The Effect Of Motherhood On Memory Retention
‘Mummy brain’ is a long-held perception that mothers are more forgetful and less attentive. A new study published yesterday, June 23, however came up with different findings.
According to the researchers, findings shows that mothers are equally as attentive, or more attentive than, non-mothers.
“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,”
“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.
“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,”
“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 attentional functioning should be taken seriously,”
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.
During the computer test, a cue box flashes for 100 milliseconds in one of two possible locations where a target image will appear on the screen. Next, an image of five arrows, each pointing left or right in consistent or conflicting directions, flashes on the screen for 500 milliseconds. Participants are then asked to press a button that corresponds to the direction of only the middle arrow.
Miller said the test measures response times and provides scores for the three main networks of attention: The alerting network helps the brain prepare for incoming stimuli; the orienting network directs the brain’s attention to something new; and the executive control network helps resolve conflicting information.
Mothers in the study were, on average, 10 years older than non-mothers. Even after controlling for age, however, the researchers found that mothers had similar alerting and orienting attention, and better executive control attention, compared to non-mothers.
“Moms were not as distracted by those outside, incongruent items,”
“It makes perfect sense that moms who have brought children into this world have more stimuli that needs to be processed to keep themselves and other humans alive, and then to continue with all the other tasks that were required before the children.”
Heightened attention isn’t always a good thing. It could become amplified with feelings of stress and isolation, which many U.S. moms experience, causing them to develop anxiety, Veile said.
“We plan to do cross-cultural investigations to further examine how narratives of motherhood and social support are associated with maternal tested attention and well-being around the world,”
