影响系统，在其位置上监测有机环境的交易，可能是敏感的内部动态信息处理。因此，作者预测刺激处理的促进应引起短暂、温和、积极的情感反应。在两项研究中，参与者观看了一系列中性图片，同时对处理难度进行了不显眼的操纵。用面部肌电图（EMG）评估情感反应。在这两项研究中，易于处理的图片在颧大肌区域引发了更高的活动，表明积极的影响。肌电图数据与对促进刺激的积极反应的自我报告相一致。研究结果表明，加工动态和情感之间存在密切联系，可能有助于理解几种偏好现象，包括单纯暴露效应。研究结果还强调了社会判断中情感偏见的潜在来源。
The affect system, in its position to monitor organismic-environmental transactions, may be sensitive to the internal dynamics of information processing. Hence, the authors predicted that facilitation of stimulus processing should elicit a brief, mild, positive affective response. In 2 studies, participants watched a series of neutral pictures while the processing ease was unobtrusively manipulated. Affective reactions were assessed with facial electromyography (EMG). In both studies, easy-to-process pictures elicited higher activity over the region of zygomaticus major, indicating positive affect. The EMG data were paralleled by self-reports of positive responses to the facilitated stimuli. The findings suggest a close link between processing dynamics and affect and may help understand several preference phenomena, including the mere-exposure effect. The findings also highlight a potential source of affective biases in social judgments.
