Motherhood and theory of mind: increased activation in affective theory of mind and emotion processing areas
There is growing evidence that parenthood changes how people face the specific needs and requests of infants and children, especially their own. However, little is known about the influence of parenthood on theory of mind, the capacity to infer mental and affective states of others and derive action predictions based on these states. It is also unclear whether the effects of parenthood generalise to inferring states of adults or are specific to children. In this study, we investigated neural activation in mothers and women without children during an affective theory of mind task that focuses on predicting action intentions from both child and adult faces. Region-of-interest analyses showed that both emotion and theory of mind areas were activated more strongly in mothers than women without children. These differences were not specific to child stimuli but occurred in response to both adult and child stimuli. Different neural recruitment of emotion and theory of mind related areas might indicate that mothers and non-mothers employ different strategies to infer action intentions from affective faces. Whether these general differences in affective theory of mind between mothers and non-mothers are due to biological or experience-related changes should be subject of further investigation.
