Generalisation of fear and avoidance along a
semantic continuum.

Abstract
Directly conditioned fear and avoidance readily generalises to dissimilar but conceptually related
stimuli. Here, for the first time, we examined the conceptual/semantic generalisation of both fear and
avoidance using real words (synonyms). Participants were first exposed to a differential fear
conditioning procedure in which one word (e.g., “broth”; CS+) was followed with brief electric
shock [unconditioned stimulus (US)] and another was not (e.g., “assist”; CS–). Next, an instrumental
conditioning phase taught avoidance in the presence the CS+ but not the CS–. During generalisation
testing, synonyms of the CS+ (e.g., “soup”; GCS+) and CS– (e.g., “help”; GCS–) were presented in
the absence of shock. Conditioned fear and avoidance, measured via skin conductance responses,
behavioural avoidance and US expectancy ratings, generalised to the semantically related, but not to
the semantically unrelated, synonyms. Findings have implications for how natural language categories
and concepts mediate the expansion of fear and avoidance repertoires in clinical contexts.
