Abstract

Using multivariate EEG decoding, we show that scene-category information follows different temporal profiles across two presentation regimes: abrupt scene appearance after a grayscale screen and gradual scene emergence during continuous visual input. Our findings demonstrate that time-resolved decoding is sensitive to stimulus-presentation context and should not be interpreted as an invariant signature of a fixed visual processing hierarchy.

• New paper! We compared EEG decoding for scenes that appeared abruptly versus scenes emerging gradually during continuous visual input. Takeaway: Presentation context matters when interpreting EEG de [bsky, 21 points, 0 comments]
