Abstract

In evaluative conditioning, a neutral conditional stimulus (CS) acquires the valence of a pleasant or unpleasant unconditional stimulus (US) after the CS and US are paired (acquisition). Valence acquired by the CS can generalise to other stimuli from the same category. Presenting the CS alone can reduce evaluative conditioning (extinction), but evaluations can return after the US is presented alone (reinstatement). The current research investigated whether extinction and reinstatement generalise to other category members (generalisation stimuli, GS). In Experiment 1, evaluations generalised in acquisition after conditioning with one category exemplar, but GS evaluations were unaffected by extinction and reinstatement. In Experiment 2, we aimed to enhance generalisation by presenting multiple category exemplars during conditioning. This strengthened the generalisation of evaluations in extinction but not reinstatement. In Experiment 3, conditioning with multiple exemplars caused explicit and implicit evaluations (measured using an affective priming task) to generalise in acquisition but not in extinction or reinstatement. The acquisition and extinction of US expectancy generalised in all experiments, but the reinstatement generalised in Experiment 3 only. Overall, we found partial evidence of evaluative generalisation during extinction (but not reinstatement) and demonstrated that the extinction and reinstatement of US expectancy generalises in evaluative conditioning.

在评价性条件反射的习得、消退和恢复过程中考察概念的泛化。
在评价性条件反射中,一个中性条件刺激(CS)在与一个愉快或不愉快的无条件刺激(US)配对(习得)后,会获得该刺激的价值。CS获得的价值感可以泛化到同类的其他刺激物上。单独呈现 CS 可以减少评价性条件反射(消退),但单独呈现 US 后,评价性条件反射又会恢复(恢复)。目前的研究调查了消退和恢复是否会泛化到其他类别成员(泛化刺激,GS)。在实验 1 中,在使用一个类别范例进行条件反射后,评价会在习得过程中泛化,但 GS 评价不受消退和恢复的影响。在实验 2 中,我们旨在通过在条件反射过程中呈现多个类别范例来增强泛化。这加强了消退时评价的泛化,但没有加强恢复时的泛化。在实验 3 中,使用多个范例进行条件反射会导致显性和隐性评价(使用情感引物任务进行测量)在获得时泛化,但在消退或恢复时则不会。在所有实验中,美国期望的获得和消退都具有普遍性,但只有在实验 3 中,恢复才具有普遍性。总之,我们发现了在消退(而非恢复)过程中评价泛化的部分证据,并证明了美国期望的消退和恢复在评价条件反射中具有泛化作用。

期刊介绍: Cognition & Emotion is devoted to the study of emotion, especially to those aspects of emotion related to cognitive processes. The journal aims to bring together work on emotion undertaken by researchers in cognitive, social, clinical, and developmental psychology, neuropsychology, and cognitive science. Examples of topics appropriate for the journal include the role of cognitive processes in emotion elicitation, regulation, and expression; the impact of emotion on attention, memory, learning, motivation, judgements, and decisions.
