タイトルCultural differences in face perception: Ecological validity, development, and mechanisms
要旨
| Recent eye-tracking studies have demonstrated cultural differences in face scanning strategies, with Western Caucasians (WC) showing triangular scanning patterns (eyes and mouth) and East Asians (EA) exhibiting central fixations (Blais et al., 2008). However, previous studies have primarily presented static faces on screen; this raises the question of whether findings extend to real-world conditions, which are not only visually complex but also characterised by social presence. In addition, the existing literature continues to describe manifestations of cultural differences in eye movement patterns, but it fails to address underlying mechanisms that can explain how culture modulates face perception. In this talk, I will present four ongoing eye-tracking studies that address these limitations: Study 1 and 2 examine cultural differences in adults’ face scanning during naturalistic dyadic interactions. Study 3 is a screen-based paradigm that aims to characterise infants’ developmental trajectory of cultural differences in face scanning as well as identify potential underlying cognitive mechanisms. Finally, Study 4 investigates infants’ face scanning strategies under real-world conditions. We also examine the role of the familial environment on the development of cultural differences in face perception by taking into account the caregivers’ scanning behaviour. Altogether, these studies aim to reveal when and how our postnatal environment shapes our social development. |
