摘要: Most adults, especially women, hold infants and objects representing infants, such as dolls, preferentially on the left side. The attention hypothesis credits effect to left-directed for perception of emotionally salient targets, faces being prime examples. Support comes from studies showing stronger visual hemispace (LVH) biases in left-holders than right-holders Chimeric Faces Test (CFT), but control tests with non-social/emotional are needed. We therefore observed young women holding a doll, book, bag, compared their scores performance CFT. also assessed handedness check its possible role. Overall, only doll elicited significant side bias, 57% all holds left, 2% middle, 41% right. On CFT, had an LVH whereas no bias either direction. Only doll-hold were consistently related CFT scores, none was side-of-hold.
