What is the minimal exposure required to process facial features? In our reply to Mamassian & Wexler in Nat Comm, we address important questions about the limits of this approach and explain why manipulating exposure duration can offer advantages over other common visibility manipulations.

1/11 New preprint! Can we register eye contact before we consciously see gaze direction? We flashed faces for just 1–5 ms and found that direct gaze facilitates face detection before explicit gaze awareness. 🧵

Conscious and unconscious eye contact at the limits of vision
Eye contact is one of the most potent social signals, but it remains unclear how little visual input is sufficient to register direct gaze, and whether such registration requires conscious awareness. ...

1/Preprint Alert🔔: Across two experiments plus a computational model, we show the visual system compresses complex scenes into summary statistics that can guide behavior without conscious access to the task-defining features. We term this the Ensemble Blindsight effect.
