Induction of conditioned avoidance via mental imagery
Open accessPublished version of a preprint
Abstract
There is a growing interest on how mental imagery may be involved in the onset and maintenance of anxiety-related disorders. Here, we used an experimental design to investigate whether a key symptom across anxiety-related disorders, namely avoidance, can be induced via mental imagery. Healthy participants first learned that one neutral stimulus (A) was associated with a mild electric shock and two other neutral stimuli (B and C) were not. They then learned to cancel the shock when A was presented, by pressing a button on a keyboard ('behavioral avoidance'). Next, they were asked to imagine that stimulus B was followed by the shock (i.e., without actual B or shock presentations; Experiment 1; N = 66) or they were shown B and asked to imagine the shock (i.e., without actual shock presentations; Experiment 2; N = 60). Finally, in the test phase, they were shown each of the three stimuli (without the shock) and given the opportunity to make the avoidance response. Results showed that participants tended to avoid B in the test phase in Experiment 1, even though it had never been presented with the shock but not in Experiment 2. We discuss how the findings may explain the acquisition of avoidance in the presentation of innocuousstimuli across anxiety-related disorders.

If patients with anxiety disorders experience intense threat imagery, they might be too anxious or unwilling to confront feared stimuli, which could explain the low attrition rates in exposure therapy.
“If patients with anxiety disorders experience intense threat imagery, they might be too anxious [27, 28] or unwilling to confront feared stimuli [28–30], which could explain the low attrition rates in exposure therapy.”

The Introduction (p. 4) proposes that mental imagery may lead to behavioral avoidance, including avoidance of innocuous stimuli by people with anxiety symptoms. The experiment described in the Abstract (p. 2) found imagery-induced avoidance in healthy participants. It does not establish that patients experiencing intense threat imagery become too anxious or unwilling to confront feared stimuli; the exposure-therapy explanation is the citing authors’ inference, not a finding of this study.

Experimental — accuracy not yet measuredMental imagery of potential threats can result in fear and avoidance learning.
“It has been emphasized in fear conditioning research that mental imagery of potential threats can result in fear and avoidance learning (e.g., Krypotos et al. 2020;Mertens, Krypotos, and Engelhard 2020;Mueller, Sperl, and Panitz 2019).”

“…via these pathways, it remains unclear why patients with anxiety symptomatology avoid innocuous stimuli, without recalling any direct or indirect (i.e., via verbal instruction or social observation) associations between these stimuli and an aversive (i.e., now the phobic) event (Rachman, 1977).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
