Examining the link between neuroticism, aversification, and approach-avoidance choice behavior
No full textThis preregistration investigates the relationship between neuroticism, trait anxiety, and aversification effects on approach-avoidance decision-making. Participants will be exposed to conditioned stimuli (CS) predicting either aversive or benign outcomes, followed by unconditioned stimuli (US) of varying intensities. We hypothesize that individuals with higher levels of neuroticism and trait anxiety will exhibit stronger subjective and physiological responses (e.g., event-related potentials, heart rate, and startle magnitude) to the same US intensity when it is preceded by an aversive CS compared to a benign CS. Furthermore, we will explore how these personality traits influence approach-avoidance choices. We hypothesize that individuals with higher neuroticism and trait anxiety will reject more trials overall and will have a higher aversification rejection rate, defined as the difference in rejection rates for the same US intensity when preceded by an aversive versus a benign CS. An exploratory mediation analysis will investigate the interactions between these personality traits, the magnitude of aversification, and aversification rejection rates. The data collected will provide insights into the association between neuroticism and trait anxiety and how aversive expectations alter the perception of stimuli (i.e., aversification), as well as how this altered perception influences approach-avoidance decision-making
Examining the neural correlates of aversification with EEG and exploring its influence on approach-avoidance choice behavior
No full textThis study investigates the neural correlates of aversification using EEG and its effects on approach-avoidance choice behavior. Participants will be exposed to conditioned stimuli (CS) predicting either aversive or benign outcomes, followed by an unconditioned stimulus (US) of varying intensities. We hypothesize that participants will exhibit stronger subjective and physiological responses (event-related potentials N1 and P2, heart rate, and startle magnitude) to the same unconditioned stimulus (US) intensity when it is preceded by an aversive conditioned stimulus (CS) compared to a benign CS. Additionally, participants will make approach-avoidance choices regarding whether to re-experience the US in exchange for a monetary reward. We aim to explore whether aversification influences approach-avoidance choices. We hypothesize that an aversified US (i.e., one preceded by an aversive CS) will be rejected more frequently than a non-aversified US (i.e., one preceded by a benign CS), indicating the impact of aversification on approach-avoidance choice behavior. The data collected will provide insight into the temporal and neural dynamics of aversification and the influence of aversification on subsequent choice behavior, with potential applications for understanding anxiety-related disorders and approach-avoidance behavior
