[HTML][HTML] Approach-avoidance decisions under threat: the role of autonomic psychophysiological states
Acutely challenging or threatening situations frequently require approach-avoidance
decisions. Acute threat triggers fast autonomic changes that prepare the body to freeze, fight …

The neurocomputational link between defensive cardiac states and approach-avoidance arbitration under threat
Avoidance, a hallmark of anxiety-related psychopathology, often comes at a cost; avoiding
threat may forgo the possibility of a reward. Theories predict that optimal approach …

Defensive freezing and its relation to approach–avoidance decision-making under threat
Successful responding to acutely threatening situations requires adequate approach–
avoidance decisions. However, it is unclear how threat-induced states—like freezing-related …

Freezing revisited: coordinated autonomic and central optimization of threat coping
K Roelofs, P Dayan - Nature Reviews Neuroscience, 2022 - nature.com
Animals have sophisticated mechanisms for coping with danger. Freezing is a unique state
that, upon threat detection, allows evidence to be gathered, response possibilities to be …

Acute threat enhances perceptual sensitivity without affecting the decision criterion
Threatening situations ask for rapid and accurate perceptual decisions to optimize coping.
Theoretical models have stated that psychophysiological states, such as bradycardia during …

Active avoidance and attentive freezing in the face of approaching threat
Defensive behaviors in animals and humans vary dynamically with increasing proximity of a
threat and depending upon the behavioral repertoire at hand. The current study investigated …

[HTML][HTML] The ecology of human fear: survival optimization and the nervous system
We propose a Survival Optimization System (SOS) to account for the strategies that humans
and other animals use to defend against recurring and novel threats. The SOS attempts to …

Understanding anxiety symptoms as aberrant defensive responding along the threat imminence continuum
R Abend - Neuroscience & Biobehavioral Reviews, 2023 - Elsevier
Threat-anticipatory defensive responses have evolved to promote survival in a dynamic
world. While inherently adaptive, aberrant expression of defensive responses to potential …

Adaptation to potential threat: the evolution, neurobiology, and psychopathology of the security motivation system
EZ Woody, H Szechtman - Neuroscience & Biobehavioral Reviews, 2011 - Elsevier
The risk of improbable, uncertain, but grave potential dangers poses unique adaptive
challenges. We argue that to manage such risks, a special motivational system evolved …

[HTML][HTML] Threat of shock and aversive inhibition: Induced anxiety modulates Pavlovian-instrumental interactions.
Anxiety can be an adaptive response to potentially threatening situations. However, if
experienced in inappropriate contexts, it can also lead to pathological and maladaptive …
