Stress, Sex, and Fear

The impact of well-known risk factors for such disorders (stress, biological sex, anxiety-related dispositions) on fear generalization will be examined. Findings from this study may provide insight into how these risk factors influence the development and/or maintenance of psychological disorders that involve overgeneralization of fear and could facilitate future approaches to their treatment.

Behavioral - Stress immediately before learning in males

Male participants will be exposed to the socially evaluated cold pressor test immediately prior to fear learning. Participants will place their dominant hand in a bath of ice cold water for up to 3 minutes. The participants will also be informed that they are being videotaped for analysis of facial expressions and be asked to stare at a camera throughout the manipulation. Immediately following the acute stressor, participants will undergo the acquisition phase of fear conditioning.

Behavioral - Sham control immediately before learning in males

Male participants will be exposed to the sham control condition (no stress) immediately prior to fear learning. Participants will place their dominant hand in a bath of lukewarm water for up to 3 minutes. Immediately following the sham control condition, participants will undergo the acquisition phase of fear conditioning.

Behavioral - Stress 30 minutes before learning in males

Male participants will be exposed to the socially evaluated cold pressor test 30 minutes prior to fear learning. Participants will place their dominant hand in a bath of ice cold water for up to 3 minutes. The participants will also be informed that they are being videotaped for analysis of facial expressions and be asked to stare at a camera throughout the manipulation. Thirty minutes following the acute stressor, participants will undergo the acquisition phase of fear conditioning.

Behavioral - Sham control 30 minutes before learning in males

Male participants will be exposed to the sham control condition (no stress) 30 minutes prior to fear learning. Participants will place their dominant hand in a bath of lukewarm water for up to 3 minutes. Thirty minutes following the sham control condition, participants will undergo the acquisition phase of fear conditioning.

Behavioral - Stress immediately before learning in females

Female participants will be exposed to the socially evaluated cold pressor test immediately prior to fear learning. Participants will place their dominant hand in a bath of ice cold water for up to 3 minutes. The participants will also be informed that they are being videotaped for analysis of facial expressions and be asked to stare at a camera throughout the manipulation. Immediately following the acute stressor, participants will undergo the acquisition phase of fear conditioning.
