For example, we interpret the face of a person with a gun as “threatening” but perceive the face of the same person with a birthday cake as “happy.” These inferences allow us to resolve uncertainties by integrating background information (e.g., the gun versus the cake) with sensory perceptions of the face to construct a coherent representation. A critical function of contextual framing is to shape our perception of faces as we interpret ongoing social interactions and determine appropriate actions. Context provides situation-specific framing to resolve ambiguity and generate predictions that guide our interpersonal behavior. Memories of our daily experiences are closely linked to the context of the event.
Our results identify theta phase shifts as mediating associations between context and face processing, supporting flexible social behavior. Contextual information is subsequently represented in the orbitofrontal cortex, where a theta phase shift binds context and face associations within theta cycles, endowing faces with contextual meanings at behavioral timescales. Here we use human intracranial electroencephalograms (EEGs) directly recorded from these regions and report bidirectional theta-gamma interactions within the amygdala-hippocampal network, facilitating contextual processing. This context-specific modulation of facial expression is thought to engage the amygdala, hippocampus, and orbitofrontal cortex however, the underlying neural computations remain unknown. Critical to our adaptive fitness, context provides situation-specific framing to resolve ambiguity and guide our interpersonal behavior.
We interpret a person’s face in a hostile situation negatively and judge the same face under pleasant circumstances positively. Context shapes our perception of facial expressions during everyday social interactions.
