当受试者被指示自我产生快乐、悲伤和愤怒的意象时，可以使用肌电图（EMG）程序检测面部肌肉活动的离散模式。先前的研究表明，抑郁的受试者在想象条件下，特别是在快乐的想象过程中，表现出衰减的面部肌电图模式。抑郁的受试者（12名）和匹配的正常人（12名）被要求产生快乐和悲伤的意象，首先是简单地思考意象，然后通过重新体验与意象相关的感觉来自我调节情感状态。连续记录面部肌电从皱眉肌，肌肉大，降口角肌和颏肌区域。据推测，这些肌肉部位将可靠地区分快乐和悲伤的意象;自我产生情感状态的指令将产生比思考指令更大的EMG差异;思考指令将是抑郁和非抑郁受试者之间差异的更敏感的指标，特别是对于快乐意象。所有3个假设均得到证实。讨论了面部肌电在正常和临床情绪状态评估中的应用，以及面部肌肉模式在情绪主观体验中的作用。
When [human] subjects are instructed to self-generate happy, sad and angry imagery, discrete patterns of facial muscle activity can be detected using electromyographic (EMG) procedures. Prior research suggested that depressed subjects show attenuated facial EMG patterns during imagery conditions, particularly during happy imagery. Depressed subjects (12) and matched normals (12) were requested to generate happy and sad imagery, first with the instruction to simply think about the imagery, and then to self-regulate the affective state by reexperiencing the feelings associated with the imagery. Continuous recordings of facial EMG were obtained from the corrugator, zygomatic major, depressor anguli oris and mentalis muscle regions. It was hypothesized, that these muscle sites would reliably differentiate between happy and sad imagery; the instruction to self-generate the affective feeling state would produce greater EMG differences than the think instructions; and that the think instructions would be a more sensitive indicator of the difference between depressed and nondepressed subjects, especially for happy imagery. All 3 hypotheses were confirmed. The application of facial EMG to the assessment of normal and clinical mood states, and the role of facial muscle patterning in the subjective experience of emotion, were discussed.
