To better understand the relationship between social anxiety and excessive reassurance seeking, the current experimental study will focus on the interpersonal consequences of reassurance seeking from the reassurance provider's perspective. In the current study, we aim to answer the following research questions: 1. How does excessive reassurance seeking affect the quality of reassurance provided over multiple attempts for reassurance? 2. Does the closeness of the relationship (close other versus acquaintance) moderate the quality of the reassurance provided? 3. How does the reassurance provider’s momentary emotional experience (i.e., Self-Assessment Maniken emotional valence and arousal ratings after each trial) change across successive reassurance attempts, and is this trajectory moderated by relationship condition (close other vs. acquaintance)? 4. What are the emotional and interpersonal consequences of excessive reassurance seeking based on the perspective of the reassurance provider? Specifically, how will providing reassurance multiple times impact the reassurance provider, in terms of their negative and positive affect, their perception of the interaction task, and feelings of relationship closeness with the interaction partner after the task? In general, will the reassurance provider experience emotional and interpersonal strain after providing excessive reassurance? 5. Will emotional and interpersonal strain for the provider be greater when imagining providing reassurance to an acquaintance or a close other? Using an online design, participants are randomized to either an imagined close other or acquaintance condition. In each condition, participants are prompted to provide repeated reassurance to a central character whose reassurance-seeking attempts are scripted by the researchers to align with social anxiety themes. All participants also complete various ratings and survey questionnaires.
