情绪是一种行动倾向，即警惕的准备状态，在所报告的情感、生理和行为方面差异很大。 然而，它们仅由两种对立的动机系统驱动，即调节对初级强化物反应的食欲和厌恶皮层下回路。 使用大型情感图片库，显示可靠的情感心理生理学，由判断的效价（食欲/愉快或厌恶/不愉快）和图片感知的唤醒来定义。 图片诱发的影响也会调节对独立呈现的惊吓探针刺激的反应。 换句话说，它们会在不愉快的图片中增强惊吓反射，并在愉快的图片中抑制惊吓反射，并且这两种效果都会因图片的高唤醒而增强。 阐明了对基本情绪、精神病理学以及定向和防御理论研究的影响。 结论强调了该方法的局限性和未来研究的有希望的路径。
Emotions are action dispositions-states of vigilant readiness that vary widely in reported affect, physiology, and behavior. They are driven, however, by only 2 opponent motivational systems, appetitive and aversive-subcortical circuits that mediate reactions to primary reinforcers. Using a large emotional picture library, reliable affective psychophysiologies are shown, defined by the judged valence (appetitive/pleasant or aversive/unpleasant) and arousal of picture percepts. Picture-evoked affects also modulate responses to independently presented startled probe stimuli. In other words, they potentiate startle reflexes during unpleasant pictures and inhibit them during pleasant pictures, and both effects are augmented by high picture arousal. Implications are elucidated for research in basic emotions, psychopathology, and theories of orienting and defense. Conclusions highlights both the approach's constraints and promising paths for future study.
