TY - JOUR PY - 2019// TI - Fear without context: acute stress modulates the balance of cue-dependent and contextual fear learning JO - Psychological science A1 - Simon-Kutscher, Kathrin A1 - Wanke, Nadine A1 - Hiller, Carlo A1 - Schwabe, Lars SP - 1123 EP - 1135 VL - 30 IS - 8 N2 - During a threatening encounter, people can learn to associate the aversive event with a discrete preceding cue or with the context in which the event took place, corresponding to cue-dependent and context-dependent fear conditioning, respectively. Which of these forms of fear learning prevails has critical implications for fear-related psychopathology. We tested here whether acute stress may modulate the balance of cue-dependent and contextual fear learning. Participants (N = 72) underwent a stress or control manipulation 30 min before they completed a fear-learning task in a virtual environment that allowed both cued and contextual fear learning.

RESULTS showed equally strong cue- and context-dependent fear conditioning in the control group. Stress, however, abolished contextual fear learning, which was directly correlated with the activity of the stress hormone cortisol, and made cue-dependent fear more resistant to extinction. These results are the first to show that stress favors cue-dependent over contextual fear learning.
