Visual awareness negativity is an early neural correlate of awareness: A preregistered study with two Gabor sizes

Published in:┬áCognitive, Affective, & Behavioral Neuroscience, Volume 18, Issue 1, 176-188 Abstract “Electrophysiological recordings are commonly used to study the neural correlates of consciousness in humans. Previous research is inconsistent as to whether awareness can be indexed with visual awareness negativity (VAN) at about 200 ms or if it occurs later. The present study was preregistered with two main aims: First, to provide independent evidence for or against the presence of VAN, and second, to study whether stimulus size may account for the inconsistent findings. Subjects were shown low-contrast Gaussian filtered gratings (Gabor patches) in the four visual quadrants. Gabor… Read More
