How Pavlov Helps Us to Understand Social Anxiety Disorder
Ivan Pavlov's classical conditioning theory offers a powerful lens for understanding social anxiety disorder (SAD). According to Pavlov, a neutral stimulus becomes a fear trigger when repeatedly paired with an aversive event (Pavlov, 1897). Social situations such as public speaking may initially be neutral but come to evoke anxiety if previously associated with humiliation or rejection. Thus, a formerly neutral social cue (conditioned stimulus CS) can elicit intense fear (conditioned response CR) after pairing with a distressing social event (unconditioned stimulus US).
From a Pavlovian perspective, individuals develop a repertoire of conditioned emotional responses that form a stable dimension of personality, namely a high tendency toward anxiety and social context. These conditioned, neutral associations become part of one's emotional structure, shaping how one responds to social cues.
The acquisition of fear through repeated CS-US pairings leads to avoidant and anticipatory anxiety. Overgeneralization, responding with fear to stimuli like the original CS, further widens the fear network (Lee et al, 2024). Extinction, though critical, often fails or is incomplete in SAD, so conditioned fear persists (Treanor et al., 2020).
Early negative social experiences may prime Pavlovian learning processes, especially in children with heightened reactivity to social cues. Conditioning can solidify into chronic social anxiety across adolescence and adulthood (Treanor et al., 2020).
SAD reflects a maladaptive condition of fear, where neutral situations become threatening through associative learning. Overgeneralization and impaired extinction (failing to learn safety in a social context) maintain the disorder (Lee et al., 2024).
Behaviorally based treatments like exposure therapy are direct applications of Pavlovian extinction. Clients are gradually and repeatedly exposed to feared social stimuli without adverse outcomes, weakening the CS-US link and fostering new learning (Craske et al., 2014). Emerging approaches like virtual reality exposure also leverage Pavlovian principles and immersive contexts (Kredlow et al., 2022).
