Expressive Suppression is a common regulation strategy, inhibiting the ongoing emotional response. Expressive Suppression have an effect on the affective、cognitive consequences. This study was to explore the influence of emotional expressive inhibition on different channels conditions(in terms of visual channel、auditory channel and cross-channels) ,to reveal the laws of affective、cognition consequences under auditory channel and cross-channels conditions.This study uses the slide-viewing paradigm to explore emotional expressive inhibition of the different conditions on the affective、cognitive consequences.Based on emotional expressive suppression on visual channel、auditory channel and audio-visual channels which evoking neutral emotion、positive emotion and negative emotional, this study receives the following major conclusions: From the point of view of different channels, the different emotional valences have an effect on affective consequence and cognition (memory); For the different emotional valences, the different channels have different effect, the following as:(1) On different channels, the suppression consequences of the different emotional valences are different. The suppression of auditory channel is better than visual channel, audio-visual channel, and memory performance is relatively better. For facial expressions on each channel: facial expression changes with the channels evoking different emotional valences. In general, facial expression of auditory channel express is significantly less than the expression of visual channel and expression of audio-visual channels. The suppression of each channel have the impact of facial expressions: on visual channels, expressive suppression reduces positive expression ,and reduces negative emotion expression, no effect on expression of neutral emotional behavior; on auditory channel suppression, there is on apparent expression in the neutral emotion, positive emotion and negative emotion, and there are not significant between control group and experimental group which don’t appear facial expression; Audio-visual expressive suppression don’t significantly reduce the positive emotional expression and negative emotion expression, but effectively reduces the facial expression of negative emotions .The subjective experience on each channel: the subjective experience changes with the different channels. In general, the subjective experience of positive emotion on auditory channel is lower than the subjective experience of visual channel, the subjective experience of auditory channel is lower than the subjective experience of audio-visual channels, and the subjective experience of emotion between visual channel and audio-visual channels isn’t significantly different. For the negative emotion on channels, there is no significant difference. Emotional expressive suppression on each channel do not decrease subjective positive and negative subjective experience.Physiological responses on each channel: physiological response changes with the channel evoking different emotional valence .In general, the activation of SCL (skin conductance level) and HRV (heart rate variability) of the expressive suppression on visual channel is higher than the activation of SCL (skin conductance level) and HRV (heart rate variability) on the auditory channel or on the audio-visual channels, the physiological activation levels between auditory channel and audio-visual channel isn’t significantly different.Memory performance on each channel: the expressive suppression on all the channels resulted in auditory memory performance decreasing, however, no effect on visual memory performance. Meanwhile, the memory performance of different channel types changes with the emotional valence and changes with the memory type(recall, recognition, visual memory).For the recall, the performance of the auditory pathways in positive emotion and negative emotion is better than the performance on the visual channel which is better than the performance on audio-visual channel, there is no significant differences in neural emotion between all the channels. For the recognition, in positive emotions, the worst performance is on the auditory pathways, and there is no significant difference between the visual channel and audio-visual channel, in negative emotions, the performance of audio-visual channel is better than visual channel. For visual memory, the performance on auditory is better than the performance on visual channel.(2) For different emotional valence, different suppression effects on different channels are different: expressive suppression of neutral emotional is different from the suppression of positive and negative emotion.For neutral emotion state, there is no significant difference between suppression group and control group; the subjective experience is no significant between suppression group and control group; Physiological response is no significant difference between suppression group and control group; Free recall performance is no significant between suppression group and control group; For the recognition is significant between different channels(auditory recognition performance is better than visual performance or audio-visual channel). For the visual memory on each channel, the performance on auditory channel is better.For positive emotion, the suppression on facial expression changes with channels: the suppression on visual channel resulted in reduction of facial expressions, there is on significant difference on auditory pathways between suppress groups and control groups .The suppression on audio-visual channel did not result in reduction of expressions. On subjective experience, the experimental group and the control group on all the channels are not significantly different. On physiological responses, the physiological responses changes with the channel: the suppression of visual channel resulted in increased physiological activation of HRV and SCL; the suppression of auditory channel or audio-visual channel in both HRV and SCL are no significant difference. On memory performance, the expressive suppression resulted in each channel auditory memory performance(recall and recognition) decreased significantly, but the visual memory performance had no effect: On visual channel, expressive suppression resulted in the reduction of recall and recognition ; On auditory channels, expressive suppression resulted in reduction of recall, However, expressive suppression do not result in reduction of recognition; Audio-visual channels, the inhibition resulted in reduction of recall and recognition; expressive suppression of each channel don’t result in performance on visual memory decreasing.For negative emotions, the expressions of expressive suppression changes with channels: suppression within visual channel resulted in reduction of facial expressions, auditory pathways to suppress and control groups did not face, audio-visual channel inhibition resulted in decreased expression of behavior. On subjective experience, the experimental group and the control group were not significantly different on all the channels. On physiological response, expressive suppression resulted in the change of physiological responses varies with channels: the visual channel expressive suppression resulted in increased physiological activation of HRV and SCL; expressive suppression on auditory channel in both HRV and SCL is no significant difference; audio-visual channel expressive suppression in both HRV and SCL is no significant difference. On memory performance, expressive suppression resulted in auditory memory performance decreased significantly in each channel, but the visual memory is no significant difference: on visual channel, the inhibition resulted in recall and word recognition memory performance decreasing; on auditory channel, expressive suppression resulted in recall memory performance decreasing, but the recognition memory was no significant difference; on audio-visual dual-channel, expressive suppression resulted in recall and word recognition memory performance decreasing. However, on visual memory, there is no significant difference between experimental group and control group.At the meanwhile, in this study,physiological dates have relationship with adult temperaments, but this relationship have changed with channels emotion evoked and experimental conditions.
