A comparison of positive vicarious learning and verbal information for reducing vicariously learned fear

EXPRESS: Observational evaluative conditioning is sensitive to relational information

Social learning represents an important avenue via which evaluations can be formed or changed. Rather than learn slowly through trial and error, we can instead observe how another person (a "model") interacts with stimuli and quickly adjust our own behaviour. We report five studies (n = 912) that focused on one subtype of social learning, observational evaluative conditioning (OEC), and how it is moderated by relational information (i.e., information indicating how a stimulus and a model's reactions are related). Participants observed a model reacting positively to one stimulus and negatively to another, and were either told that these reactions were genuine, faked, or opposite to the model's actual feelings. Stimulus evaluations were then indexed using ratings and a personalised Implicit Association Test (pIAT). When the model's reactions were said to be genuine, OEC effects emerged in the expected direction. When the model's reactions were said to be faked, the magnitude of self-reported, but not pIAT, effects was reduced. Finally, stating that the model's reactions were opposite to his actual feelings eliminated or reversed self-reported effects and eliminated pIAT effects. We consider how these findings relate to previous work as well as mental-process theories.

Preventing and reducing fear using positive modelling: A systematic review of experimental research with children

Fear of specific stimuli is thought to develop through associative learning mechanisms and research indicates that a form of observational (vicarious) learning known as positive modelling can counter these effects. This systematic review examined and synthesised the experimental positive modelling literature to establish its efficacy for reducing fear. Psych Info, Medline and the Psychology and Behavioural Science Collection databases were systematically searched until August 2021. Of the 1,677 papers identified, 18 experiments across 14 articles met the inclusion criteria. In the majority of these, positive modelling was found to lower fear levels in one or more of three procedures: fear prevention, fear reduction and fear reversal. Procedures inform prevention and treatment initiatives for specific phobias in several ways. The overall efficacy of positive modelling techniques and the ease in which they can be implemented highlight the importance of further research to evaluate their inclusion in prevention and treatment interventions. More research is required to establish the longevity and transferability of positive modelling.

Watch and Learn: Vicarious Threat Learning across Human Development

Vicarious threat learning is an important pathway in learning about safety and danger in the environment and is therefore critical for survival. It involves learning by observing another person's (the demonstrator) fearful responses to threat and begins as early as infancy. The review discusses the literature on vicarious threat learning and infers how this learning pathway may evolve over human development. We begin by discussing the methods currently being used to study observational threat learning in the laboratory. Next, we focus on the social factors influencing vicarious threat learning; this is followed by a review of vicarious threat learning among children and adolescents. Finally, we examine the neural mechanisms underpinning vicarious threat learning across human development. To conclude, we encourage future research directions that will help elucidate how vicarious threat learning emerges and how it relates to the development of normative fear and pathological anxiety.
