Acute threat enhances perceptual sensitivity without affecting the decision criterion

Lycia D. de Voogd et al.

Summary: In threatening situations, individuals may rely more on bottom-up sensory processing rather than prior expectations to make perceptual decisions. Changes in heart rate may contribute to increased perceptual sensitivity.

Freezing revisited: coordinated autonomic and central optimization of threat coping

Karin Roelofs et al.

Summary: When animals anticipate a threat, they freeze and become temporarily immobile. Freezing allows for the coordination of cognitive and somatic processes, preparing the animal for action. It is not a passive fear state, but rather a state that helps conceal overt responses while optimizing sensory processing and action preparation.

Defensive freezing and its relation to approach-avoidance decision-making under threat

Felix H. Klaassen et al.

Summary: Successful responding to acutely threatening situations requires adequate approach-avoidance decisions. However, the impact of threat-induced states, like freezing-related bradycardia, on decision-making remains unclear. This study found that individual action-tendencies and bradycardia influenced choice behavior under threat. Threat-related bradycardia interacted with subjective value, depending on the action-context, affecting decision-making.
