Threat impairs flexible use of a cognitive map
B Silston, KN Ochsner, M Aly - Motivation and Emotion, 2023 - Springer
Goal-directed behavior requires adaptive systems that respond to environmental demands.
In the absence of threat (or presence of reward), individuals can explore many behavioral …

[PDF][PDF] Interactive cognitive maps support flexible behavior under threat
In social environments, survival can depend upon inferring and adapting to other agents'
goal-directed behavior. However, it remains unclear how humans achieve this, despite the …

[HTML][HTML] Spatial navigation under threat: aversive apprehensions improve route retracing in higher versus lower trait anxious individuals
Spatial navigation is a basic function for survival, and the ability to retrace a route has direct
relevance for avoiding dangerous places. This study investigates the effects of aversive …

The path more travelled: Time pressure increases reliance on familiar route-based strategies during navigation
Navigating large-scale environments involves dynamic interactions between the physical
world and individuals' knowledge, goals, and strategies. Time pressure can result from self …

Thinking about threats: Memory and prospection in human threat management
Humans have evolved mechanisms for the detection and management of possible threats in
order to abate their negative consequences for fitness. Internally generated ('detached') …

Threat learning impairs subsequent memory recombination with past episodes
To successfully predict important events, the representations in memory on which we rely
need to be constantly updated and transformed to best reflect a complex and dynamic world …

Evidence for a minimal role of stimulus awareness in reversal of threat learning
In an ever-changing environment, survival depends on learning which stimuli represent
threat, and also on updating such associations when circumstances shift. It has been …
