The association between facial expressions and the memory color effect has been elucidated through a collaborative effort involving the Cognitive Neurotechnology Unit and the Visual Perception and Cognition Laboratory from Toyohashi University of Technology’s Department of Computer Science and Engineering. The memory color effect refers to the phenomenon by which knowledge of the typical color of a specific object (the memory color) influences the recognition of its actual color. The study revealed that angry and fearful faces are more affected by the memory color effect than neutral faces in terms of color recognition, and that memory color varies depending on facial expression.
