In the emotion literature, appraisals of an event's pleasantness and goal conduciveness are often considered as interchangeable and subsumed under the term valence. Some appraisal theories, however, emphasize that there is a conceptual difference between these two appraisals. With the current study, we investigated whether such a conceptual difference would be reflected in different somatovisceral response profiles for intrinsic pleasantness and goal conduciveness. Participants viewed unpleasant and pleasant pictures (intrinsic pleasantness) and performed either goal conducive (i.e., decreasing the size of unpleasant pictures, increasing the size of pleasant pictures) or goal obstructive (i.e., increasing the size of unpleasant pictures, decreasing the size of pleasant pictures) arm movements. Our data suggest that the two appraisals have somewhat similar, but not identical, response patterns. Thus, our results emphasize the importance of distinguishing between intrinsic pleasantness and goal conduciveness. Moreover, we find evidence that the efferent effects of the two appraisals combine multiplicatively, and that predictability of goal conduciveness may influence the impact of goal conduciveness appraisals on somatovisceral responding.
在情绪文献中,人们通常认为对事件的愉悦性和目标适宜性的评价是可以互换的,并归入效价这一术语之下。然而,一些评价理论强调这两种评价之间存在概念上的差异。在本研究中,我们探讨了这种概念上的差异是否会反映在内在愉悦性和目标适宜性的不同躯体-内脏反应模式中。参与者观看不愉快和愉快的图片(内在愉悦性),并执行目标促进(即减小不愉快图片的大小,增大愉快图片的大小)或目标阻碍(即增大不愉快图片的大小,减小愉快图片的大小)手臂运动。我们的数据表明,这两种评价具有相似但不完全相同的反应模式。因此,我们的结果强调了区分内在愉悦性和目标适宜性的重要性。此外,我们发现证据表明,这两种评价的传出效应是相乘的,并且目标适宜性的可预测性可能会影响目标适宜性评价对躯体-内脏反应的影响。
