In the present study we test the hypothesis that the effect of mood congruence in autobiographical recall is underlain by mood. Thirty-eight female participants were subjected to positive, negative and neutral mood inductions, and then asked to recall three personal memories. Participants? mood was assessed using self-report questionnaires and by electromyograph (EMG) measurements of corrugator supercilii and zygomaticus major muscle activity. We replicated the congruence effect between the mood inductions and the valence of the participants? recalled memories. Furthermore, this effect was mediated by mood, as measured by EMG and self-report questionnaires. The results suggest that mood influences the mood congruence effect in a way that cannot be explained by semantic priming alone.

AbstractTime perception relies on the motor system. Involves core brain regions of this system, including those associated with feelings generated from sensorimotor states. Perceptual timing is also distorted when movement occurs during timing tasks, possibly by interfering with sensorimotor afferent feedback. However, it is unknown if the perception of time is an active process associated with specific patterns of muscle activity. We explored this idea based on the phenomenon of electromyographic gradients, which consists of the dynamic increase of muscle activity during cognitive tasks that require sustained attention, a critical function in perceptual timing. We aimed to determine whether facial muscle dynamic activity indexes the subjective representation of time. We asked participants to judge stimuli durations (varying in familiarity) while we monitored the time course of the activity of the zygomaticus-major and corrugator-supercilii muscles, both associated with cognitive and affective feelings. The dynamic electromyographic activity in corrugator-supercilii over time reflected objective time and this relationship predicted subjective judgments of duration. Furthermore, the zygomaticus-major muscle signaled the bias that familiarity introduces in duration judgments. This suggests that subjective duration could be an embodiment process based in motor information changing over time and their associated feelings.

Images of pleasant scenes usually produce increased activity over the zygomaticus major muscle, as measured by electromyography (EMG), while less activity is elicited by unpleasant images. However, increases in zygomaticus major EMG activity while viewing unpleasant images have occasionally been reported in the literature on affective facial expression (i.e., “grimacing”). To examine the possibility that individual differences in emotion regulation might be responsible for this inconsistently observed phenomenon, the habitual emotion regulation tendencies of 63 participants (32 women) were assessed and categorized according to their regulatory tendencies. Participants viewed emotionally salient images while zygomaticus major EMG activity was recorded. Participants also provided self-report ratings of their experienced emotional valence and arousal while viewing the pictures. Despite demonstrating intact affective ratings, the “grimacing” pattern of zygomaticus major activity was observed in those who were less likely to use the cognitive reappraisal strategy to regulate their emotions.

AbstractDepressed individuals are biased to perceive, interpret, and judge ambiguous cues in a negative/pessimistic manner. Depressed mood can induce and exacerbate these biases, but the underlying mechanisms are not fully understood. We theorize that depressed mood can bias ambiguity processing by altering one’s subjective emotional feelings (e.g. pleasantness/unpleasantness) of the cues. This is because when there is limited objective information, individuals often rely on subjective feelings as a source of information for cognitive processing. To test this theory, three groups (induced depression vs. spontaneous depression vs. neutral) were tested in the Judgement Bias Task (JBT), a behavioral assay of ambiguity processing bias. Subjective pleasantness/unpleasantness of cues was measured by facial electromyography (EMG) from the zygomaticus major (ZM, “smiling”) and from the corrugator supercilii (CS, “frowning”) muscles. As predicted, induced sad mood (vs. neutral mood) yielded a negative bias with a magnitude comparable to that in a spontaneous depressed mood. The facial EMG data indicates that the negative judgement bias induced by depressed mood was associated with a decrease in ZM reactivity (i.e., diminished perceived pleasantness of cues). Our results suggest that depressed mood may bias ambiguity processing by affecting the reward system.

Human adults automatically mimic others' emotional expressions, which is believed to contribute to sharing emotions with others. Although this behaviour appears fundamental to social reciprocity, little is known about its developmental process. Therefore, we examined whether infants show automatic facial mimicry in response to others' emotional expressions. Facial electromyographic activity over the corrugator supercilii (brow) and zygomaticus major (cheek) of four- to five-month-old infants was measured while they viewed dynamic clips presenting audiovisual, visual and auditory emotions. The audiovisual bimodal emotion stimuli were a display of a laughing/crying facial expression with an emotionally congruent vocalization, whereas the visual/auditory unimodal emotion stimuli displayed those emotional faces/vocalizations paired with a neutral vocalization/face, respectively. Increased activation of the corrugator supercilii muscle in response to audiovisual cries and the zygomaticus major in response to audiovisual laughter were observed between 500 and 1000 ms after stimulus onset, which clearly suggests rapid facial mimicry. By contrast, both visual and auditory unimodal emotion stimuli did not activate the infants' corresponding muscles. These results revealed that automatic facial mimicry is present as early as five months of age, when multimodal emotional information is present.
