“…Boyle, Roche, Dymond, and Hermans (2014) first exposed participants to fear conditioning in which one word was designated CS+ (e.g., broth) by pairing it with the presentation of shock, and another word was designated CS-(e.g., assist) and never followed by shock. In the next phase, an avoidance response (a space bar press) was established for the CS+, which cancelled the presentation of the scheduled shock.…”

Fear generalization, in which conditioned fear responses generalize or spread to related stimuli, is a defining feature of anxiety disorders. The behavioral consequences of maladaptive fear generalization are that aversive experiences with one stimulus or event may lead one to regard other cues or situations as potential threats that should be avoided, despite variations in physical form. Theoretical and empirical interest in the generalization of conditioned learning dates to the earliest research on classical conditioning in nonhumans. Recently, there has been renewed focus on fear generalization in humans due in part to its explanatory power in characterizing disorders of fear and anxiety. Here, we review existing behavioral and neuroimaging empirical research on the perceptual and non-perceptual (conceptual and symbolic) generalization of fear and avoidance in healthy humans and patients with anxiety disorders. The clinical implications of this research for understanding the etiology and treatment of anxiety is considered and directions for future research described.

“…This process may be particularly relevant for anxiety disorders whose symptoms concern situations that have not been directly experienced, but whose aversive nature is inferred from fear conditioning in related scenarios (140, 141). A small body of experimental work provides evidence for such “symbolic” fear generalization (142–145). …”

Computational methods are increasingly being applied to the study of psychiatric disorders. Often, this involves fitting models to the behavior of individuals with subclinical character traits that are known vulnerability factors for the development of psychiatric conditions. Anxiety disorders can be examined with reference to the behavior of individuals high in “trait” anxiety, which is a known vulnerability factor for the development of anxiety and mood disorders. However, it is not clear how this self-report measure relates to neural and behavioral processes captured by computational models. This paper reviews emerging computational approaches to the study of trait anxiety, specifying how interacting processes susceptible to analysis using computational models could drive a tendency to experience frequent anxious states and promote vulnerability to the development of clinical disorders. Existing computational studies are described in the light of this perspective and appropriate targets for future studies are discussed.

“…O presente estudo apresenta um avanço na metodologia utilizada -o uso de medidas de relato verbal típicas de investigações sobre condicionamento clássico de medo/ansiedade (e.g., Bennett et al, 2015;Boyle, Roche, Dymond, & Hermans, 2016;Vervoort, Vervliet, Bennett, & Baeyens, 2014). Estudos anteriores (e.g., Perez et al, 2019) sugerem que as medidas de expectativa de US, valência de estímulo e diferencial semântico são sensíveis a generalização simbólica de função aversivas.…”

O presente estudo teve como objetivo medir a transformação de função de estímulos após a realização de um exercício da ACT – a metáfora ‘Folhas na Correnteza’. Participaram do estudo 19 adultos, em um delineamento experimental pré-pós teste de grupo único. Procedimento experimental: Fase 1: questionários iniciais; Fase 2: Treino (MTS) relacional para estabelecer duas classes de estímulos equivalentes, A1B1C1D1 e A2B2C2D2; Fase 3: condicionamento aversivo e ensino de respostas de esquiva (para A1) e aproximação (para A2); Fase 4: Pré-teste de transferência de função (para C1 e C2) com medidas binárias (tarefa de esquiva e aproximação) e contínuas (escalas diversas de auto-relato); Fase 5: (VI): Intervenção (Metáfora Folhas na Correnteza). Fase 6: Pós-teste de transferência de função (ver Fase 4). A comparação dos resultados pré e pós intervenção indicam mudanças sutis nas medidas de relato verbal sobre a aversividade dos estímulos. Não houve efeito sobre a resposta de esquiva.
