Vigour in active avoidance.

Area of Science:

• Cognitive Neuroscience
• Behavioral Economics
• Decision Science

Background:

• Learning about potential catastrophes solely through trial and error is maladaptive.
• Excessive resource allocation to disaster aversion can negatively impact quality of life, manifesting as anxiety and paranoia.

Purpose of the Study:

• To develop and utilize a novel immersive task to investigate how individuals adjust effort expenditure (vigor) to avoid negative consequences.
• To explore the relationship between perceived threat, emotional states, and effortful avoidance behaviors in simulated disaster scenarios.

Main Methods:

• Development of an immersive task to simulate disaster scenarios and measure participant vigor.
• Recruitment of 118 participants to engage in the disaster avoidance task.
• Analysis of effort expenditure in relation to baseline catastrophe probability and subjective emotional states.

Main Results:

• Participants exerted effort to avoid disaster-associated states, modulating vigor based on the baseline probability of catastrophe.
• Effort expenditure aligned with theoretical predictions regarding risk assessment and avoidance.
• Negative subjective emotional states correlated with both threat level and increased vigor during disaster scenarios.

Conclusions:

• This study provides the first description of effort expenditure in the context of irreversible losses.
• Findings have significant implications for understanding and potentially treating disorders characterized by excessive avoidance behaviors.
• The developed task offers a novel paradigm for studying effort-based decision-making under threat.
