タイトル：Early sensitivity to facial cues to trustworthiness
要旨：Sensitivity to social cues of trustworthiness – i.e., those facial configurations we use to establish whether a stranger is approaching us safely or hostilely – is a crucial and adaptive social skill. Although much research has been done on delineating the behavioural and neural mechanisms subtending adults’ sensitivity to facial cues of trustworthiness, how this ability develops in time has been underinvestigated. Evidence from children suggest that 3-year-olds are able to judge how ‘mean’ or ‘nice’ a person is, and by the age of 6 these judgements acquire the same level of consistency as those provided by the adults (Cogsdill, Todorov, Spelke, & Banaji, 2014). More recently, studies with preverbal infants have found evidence of sensitivity to facial cues to trustworthiness at 6 months, when infants showed neural discrimination between neutral faces and faces that lay at the extreme opposites of the trustworthiness continuum (i.e., very trustworthy and very untrustworthy) (Jessen & Grossmann, 2016, 2017, 2019), and a behavioral preference towards very trustworthy faces with respect to neutral and very untrustworthy ones (Jessen & Grossmann, 2016; Sakuta, Kanazawa, & Yamaguchi, 2018). However, all the existing developmental studies used computer-generated male faces as stimulus material, which raises important issues of ecological validity, leading to underestimation, or possibly even underestimation, of infants’ sensitivity to facial cues to trustworthiness. To overcome this limitation, we measured infants’ behavioral and electrophysiological responses to very trustworthy, very untrustworthy and neutral faces using real face images taken from a previously validated trustworthiness continuum created by manipulating parametrically two averaged female face identities. Overall, our results confirm previous demonstrations of early tuning to those facial cues that adults use to generate trustworthiness judgements, and show that neural sensitivity to these cues are modulated by individual differences in temperamental traits.
