Adding imagery rescripting during extinction leads to less ABA renewal.
Although extinction is highly effective in reducing a conditioned fear response, return of the fear response (renewal) outside the extinction context often occurs. The present study investigated whether US devaluation, through imagery rescripting during extinction, resulted in less renewal than mere extinction. ⋯ The results indicated that renewal of the US expectancy ratings was reduced if imagery rescripting (ABAir) was added to mere extinction (ABAno). Next to the reduction in renewal, imagery rescripting (ABAir) also resulted in the devaluation of the US valence, indicating that the mental representation of the US had changed. These findings are not only in line with contemporary conditioning theories, but also suggest that adding imagery rescripting to extinction might be beneficial in the treatment of anxiety problems.
