Modifying Exploration
BehavioralParticipants in this group will use a mobile phone sensor data application that uses an accelerometer, Wireless Fidelity (WiFi) and/or GPS designed for smartphone devices. This technology allows the phones to capture information automatically and passively on the participant's activity. The application will be collecting participants' data 24 hours a day, 7 days a week. Participants will be asked to make alterations to their exploration levels approximately 20 days of their participation in the study.

Trial outcomes
Primary outcomes
1
Change in positive emotional response as measured by ecological momentary assessment
Emotional response will be measured by computing a total mean score of "happy", "excited", "content", "attentive", "relaxed". The total mean score ranges from 0 to 100, with higher scores indicating greater positive emotional response.
Time frame
Baseline, up to 6 monthsSecondary outcomes
1
