  "abstract": "An approach-avoidance conflict (AAC) arises when the same action promises reward but also carries potential harm. Here, we examined how humans initiate and sustain engagement under such conflict using an online foraging-inspired AAC task. Eighty-seven participants repeatedly encountered visual search fields associated with four instructed reward-punishment states and decided whether to enter each field and how extensively to search it, allowing us to distinguish passive avoidance as withheld entry from active within-field avoidance as early search termination. Participants committed to search more often and explored more extensively when expected rewards were high and punishments were low. Agent-based behavioral modeling indicated that initial and sustained engagement could be characterized at different levels of behavioral granularity: commitment to search was best explained by additive reward-punishment evaluation with state-independent trial drift, whereas search extent was best captured by a click-wise stopping process inspired by the marginal value theorem, a foraging account of when to leave a current patch for alternatives. These findings suggest that avoidance under conflict is not a single decision, but unfolds across separable decisions about whether to engage, how long to persist, and when to leave.",
