There’s a time and a face: The time course of composite face processing.

Faces are considered a special class of holistically-processed object. The composite face task is widely-used tool to infer holistic processing. In this task, recognition 1 half shown be hampered by interference from the other face. Although effect has been documented numerous times, when used in different paradigms, faces do not always exhibit effects consistent with present study explored cause these discrepant findings combining signal-to-respond paradigm. amount time make decision was manipulated introducing response signal, and resulting changes accuracy were mapped over course processing, which then fit speed-accuracy trade-off model. We found that processing emerges late after approximately 400 ms for easy-to-discriminate 1000 difficult-to-discriminate faces. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
