Brief Summary
For this study, community participants visited the PI's psychophysiology lab for a single experimental session. In this study, participants completed a brief mood measure, followed by a task training in which a research assistant described and gave examples of cognitive reappraisal in response to negative images. Participants were then randomly assigned to positive or neutral emotion induction conditions, delivered by virtual reality. Then, participants completed an event-related, picture-based cognitive reappraisal task for 23 minutes. Following the task, participants once again responded to a mood measure, completed post-task questionnaires (individual difference measures) and answered a series of questions regarding the task they completed, including difficulty of regulation, or any images that were personally relevant. The investigators predicted that the positive emotion induction would result in powerful effects on self-reported emotion, which may or may not interact with the cognitive reappraisal condition.

Outcome Measures
Primary Outcomes (3)
Mood Ratings (Pos)
Before putting on the VR headset and at the end of the experiment, participants used the modified Differential Emotions Scale (mDES; Fredrickson, 2013; Izard, 1977) to rate their current mood. We defined the mDES as a mood measure because it was intended to measure participants' current mood absent of a stimulus intended to evoke an emotional response (Rosenberg,1998). The mDES consists of 20 questions and is comprised of two sub-scales for positive and negative emotions with 10 questions for each subscale respectively. Scales are comprised of averaging all positive scores together and all negative scores together. In our study, participants were asked to rate their current experience of all 20 emotions on a five-point Likert Scale (1 - not at all to 5 - Extremely). Minimum socre = 1, maximum score = 5. Higher scores indicate higher levels of positive/negative mood.
Baseline, and post-reappraisal task
Means of Self-reported Emotion Ratings
The mean of each negative and positive emotion score were calculated post-reappraisal task. Higher scores indicate higher positive and negative emotions. The scale for both positive and negative was 1 - 9 where 1 was not positive at all/not negative at all and 9 was very positive/very negative. The minimum score was 1 and the maximum score was 9.
During the reappraisal task, individual ratings for each picture were taken immediately after viewing the image. The mean rating across all images was computed after the experiment was complete.
Mood Induction Ratings
After the VR induced mood induction, and prior to starting the reappraisal task participants rated their positive and negative emotions on a 1-9 scale, where 1 is not at all and 9 is extremely.

Study Arms (2)
Positive VR Scene
EXPERIMENTALParticipants will explore a virtual reality (VR) environment of a beach scene. Participants will be randomly assigned (between subjects) to beach or office scene. VR will be presented on an Occulus Rift device.
Neutral VR Scene
EXPERIMENTALParticipants will explore a virtual reality (VR) environment of a neutral office scene. Participants will be randomly assigned (between subjects) to beach or office scene. VR will be presented on an Occulus Rift device.
Interventions
Participants are expected to have a positive emotional response to the more positive beach scene.
Participants are expected to have a neutral emotional response to the neutral office scene.
