Learning to predict threat from environmental cues is a fundamental skill in changing
environments. This aversive learning process is exemplified by Pavlovian threat …

Electrophysiological studies in rodents allow recording neural activity during threats with
high temporal and spatial precision. Although fMRI has helped translate insights about the …

During fear conditioning, pupil size responses dissociate between conditioned stimuli that
are contingently paired (CS+) with an aversive unconditioned stimulus, and those that are …

Fear conditioning and extinction is a construct integral to understanding trauma-, stress-and
anxiety-related disorders. In the laboratory, associative learning paradigms that pair …

Pathological fear and anxiety disorders can have debilitating impacts on individual patients
and society. The neural circuitry underlying fear learning and extinction has been known to …

Freezing to impending threat is a core defensive response. It has been studied primarily
using fear conditioning in non‐human animals, thwarting advances in translational human …

Appetitive Pavlovian conditioning is a learning mechanism of fundamental biological and
pathophysiological significance. Nonetheless, its exploration in humans remains sparse …

The ability to flexibly transition between defensive states is crucial for adaptive responding in
life‐threatening situations. Potentially threatening situations typically induce a sustained …

Pavlovian fear conditioning is widely used as a laboratory model of associative learning in
human and nonhuman species. In this model, an organism is trained to predict an aversive …

This study aimed at evaluating the autonomic response to pleasant affective touch in
children with Autism Spectrum Disorders (ASD) and age-matched typically developing (TD) …
