- 요약Appetitive and aversive motivation shape human behavior, with the former enabling us to pursue objects that provide survival benefits and the latter prompting withdrawal from harm. The biological significance has spurred decades of research on the functioning of motivation systems and their underlying neural mechanisms. Nonetheless, existing research often relied on relatively static or non-interactive experimental paradigms, whereas our understanding of appetitive and aversive motivation under interactive and dynamic environments remains limited. To address this gap in the literature, this dissertation comprised three studies employing a dynamic predator-prey video game, which required the subject to survive in a virtual environment by continuously taking appropriate approach-avoidance actions. Study one interrogated the dynamics of appetitive and aversive motivation when people navigated this virtual environment. The primary finding is that motivation, and the related emotional and cognitive responses, at any moment was shaped by the interplay between exogenous environmental influences (e.g., how close the rewards/threats were) and endogenous homeostatic demand (e.g., an organism's pressing need to acquire food sources).Study two focused on the scenarios where rewards and threats coexisted, examining how the human brain processed the conflicting motivation under dynamic settings. The data revealed two distinct neural mechanisms: one involving the salience network and sensorimotor regions for detecting conflict stimuli and shifting behaviors, and another involving the executive control and default mode networks for maintaining selected behavioral patterns.Study three revisited the negativity bias phenomenon by equalizing the intensity of appetitive and aversive stimuli in a dynamic environment. Results showed stronger physiological indicators of orienting response and arousal to aversive stimuli compared to equally intense appetitive stimuli. In the brain, while regions implicated in affective processing (e.g., the insula cortex) responded more strongly to threats, some other parts (e.g., the visual cortex) prioritized reward processing.Together, the three studies advance our understanding of the physiological and neural mechanisms of appetitive and aversive motivation in dynamic environments.
