Forskargruppen studerar effekter av emotion på uppmärksamhet och medvetande. Exempelvis studeras om emotionella bilder kan helt ignoreras och om emotionell bearbetning sker även om deltagare inte är medvetna om bildinnehåll. Vi använder oss av experimentalpsykologiska manipulationer (backward masking, binocular rivalry, perceptual load, working memory load) i kombination med periferpsykofysiologiska mått (hudkonduktans, puls med mera) och elektroencefalografi (EEG).
