This dataset contains data for behavioural outcomes from the audiovisual emotion recognition task described in the paper: "High Trait Anxiety Enhances Optimal Integration of Auditory and Visual Threat Cues". Participants made emotional judgements about dynamic face and voice stimuli, having to classify them as being either happy, angry or sad by a making a speeded key press. The task included three different stimulus modality conditions: visual-only (faces), audio-only (voices) and audiovisual (faces and voices together). The stimuli were approximately 500ms long and visual noise was added to the central face region of the videos by the addition of a Gaussian blur. Participants were screened before they were recruited in the study such that only individuals with a trait anxiety score of 37 or below (low anxiety group) and 48 or above (high anxiety group) were included. The trait subscale of the Spielberger State-Trait Anxiety scale was used to measure trait anxiety.
