Spatial attention affects the early processing of neutral versus fearful faces when they are task-irrelevant: a classifier study of the EEG C1 component (2018)
Journal Article
Acunzo, D., MacKenzie, G., & Van Rossum, M. (2019). Spatial attention affects the early processing of neutral versus fearful faces when they are task-irrelevant: a classifier study of the EEG C1 component. Cognitive, Affective, and Behavioral Neuroscience, 19(1), 123–137. doi:10.3758/s13415-018-00650-7

EEG studies suggest that the emotional content of visual stimuli is processed rapidly. In particular, the C1 component, which occurs up to 100 ms after stimulus onset and likely reflects activity in primary visual cortex V1, has been reported to be s... Read More

Generic emergence of objectivity of observables in infi nite dimensions (2018)
Journal Article
