The potential role of robust face representations learned within families when searching for one’s child in a crowd

Abstract

AbstractOwn child’s face is one of the most socially salient stimuli for parents, and a faster search for it than for other children’s faces may help provide warmer and more sensitive care. However, it has not been experimentally examined whether parents find their child’s face faster. In addition, although own child’s face is specially processed, the search time for own child’s face may be similar to that for other socially salient stimuli, such as own or spouse’s faces. This study tested these possibilities using a visual search paradigm. Participants (parents) searched for their child’s, own, spouse’s, other child’s, same-sex adult’s, or opposite-sex adult’s faces as search targets. Our findings indicate that both mothers and fathers identified their child’s face more quickly than other children’s faces. Similarly, parents found their own and spouse’s faces more quickly than other adults’ faces. Moreover, the search time for family members’ faces increased with the number of faces on the search display, suggesting an attentional serial search. These results suggest that robust face representations learned within families and close relationships can support reduced search times for family members’ faces.
