Cue Reactivity in Virtual Reality: The Role of Context
The objectives of this proposal are to examine the role of context in a virtual reality (VR) environment and to explore the extent to which cues (i.e., contextual cues or explicit smoking cues) influence craving and physiological arousal within VR.
The current study seeks to determine whether smokers, placed in the context of a VR convenience store devoid of explicit smoking cues, will experience less craving and physiological arousal, compared to exposure to the same VR environment containing explicit smoking cues. This important line of inquiry will help clarify the influence of environmental contexts that may contribute to the overall reactivity effects (e.g., craving, arousal) smokers experience when confronted with cues associated with smoking.

|Official Title:||Cue Reactivity in Virtual Reality: The Role of Context|
- Differences in craving and arousal among four scenarios based on repeated survey measure [ Time Frame: Total participation time about 90 minutes; Overall study period (assessment & surveys) approximately 2 years ] [ Designated as safety issue: No ]Analyses on craving and arousal measures between-subjects to discern any differences in craving and arousal among the two sets of scenarios. After providing breath and saliva samples, seated participants complete questionnaires and smoke one cigarette to control for variability in time since last cigarette. First 5 questionnaires take approximately 35 minutes to complete, and another, completed after the VR session, approximately 10 minutes.
