Appraisal-driven emotional response patterning: testing the predicted coherence between central and peripheral effects of novelty and intrinsic pleasantness evaluation

Componential appraisal theory of emotion, especially the Component Process Model (Scherer, 1984, 2001) suggests a concrete mechanism underlying the elicitation and differentiation of emotions, based on individuals’ subjective appraisals of events. Two fundamental assumptions of the Component Process Model are that the appraisal results (i.e., the outcomes of successive evaluation checks) 1) occur in a fixed sequence, and 2) directly drive response patterning of efferent systems (e.g., hormonal and autonomic reactions, motor expression, and action preparation) in order to support adaptive reactions in line with the appraisal results. We empirically tested these assumptions for the early appraisals of novelty and intrinsic pleasantness, using a multimodal approach. Novelty and intrinsic pleasantness were manipulated using an oddball paradigm with affective pictures, while central (i.e., electroencephalographic brain activity (EEG)) and peripheral (skin conductance, facial muscle activity, and pupil dilation) physiological effects were simultaneously measured. For the first time, our results show effects of novelty and intrinsic pleasantness on combined EEG and peripheral measures, in line with Component Process Model predictions. We argue that directly relating peripheral physiological measures to EEG markers of specific appraisal results can help to identify consistent efferent response patterns associated with emotional experiences and, conversely, provide support for the affective nature of the EEG patterns.
