State anxiety and emotional face recognition in healthy volunteers (study two - replication)

Experimental replication study (n = 44) investigating effects of state anxiety on emotional face processing. Participants attended one session and completed two inhalations: one of 7.5% carbon dioxide-enriched air (state anxiety condition) and one of medical air (placebo condition). During each inhalation participants completed a six-alternate forced choice task measuring recognition accuracy and sensitivity of six emotional expressions and a two alternate forced choice task measuring interpretation bias of composite emotional expressions (i.e., morphs of anger and happiness). Participants in this study were consented under procedures that did not include consent for data to be made open.
