This repo contains the analysis code for our project investigating the temporal dynamics of object-scene integration using MVPA. Our work focuses on the role of the N300/N400 complex in object perception.

Highlights

  • We demonstrate above chance decoding performance of object-scene violations.
  • Early object-scene integration shares neural patterns with late stages.
  • No evidence of different processes underlying the N300 and N400 effects.
  • Context-sensitive processes interact with perceptual stages of object recognition.
