Abstract: Interruptions during consumer decision making are ubiquitous. In seven studies, we examine the consequences of a brief interruption during a financial risk decision. We identify a fundamental feature inherent in an interruption's temporal structure - a repeat exposure to the decision stimuli - and find that this re-exposure reduces decision stimuli's subjective novelty. This reduced novelty in turn reduces decision makers' apprehension and increases the amount of risk that they take in a wide range of financial risky decision contexts. Consistent with our theoretical framework, this interruption effect disappears when a stimulus's subjective novelty is restored after an interruption. We further find that these consequences are unique to interruptions and do not result from other interventions (e.g., time pressure and elongated thinking); this is because an interruption's unique temporal structure (which results in a repeat exposure to the decision stimuli) underlies its consequences. Our findings shed light on how and when interruptions during decision making can influence risk taking.
