Visual, Auditory Stimulation Of Emotional Arousal Effect And Influence On The Micro Expression Recognition Ability

Objectives:(1)To explore the visual, auditory stimulation to stimulate role of emotions and compare their differences;(2) Effect on the micro expression recognition of visual and auditory stimuli conditions and their comparison.Methods:This was an experimental study. Take the way of recruiting volunteers, recruited150volunteers, including75boys,75girls. They were randomly divided into5groups,4experimental groups and1control group.4experimental groups respectively:positive/negative visual stimulation group, positive/negative auditory stimulation group, each group of30people. The first part through the experimental study, the difference of positive and negative visual, auditory stimulation under conditions of emotional arousal level and two kinds of stimulation; the second part through the investigation and study, with the help of related psychological scale of coping styles, personality characteristics and the relationship between psychological factors and emotional excitation; the third part, through the experimental study visual stimuli, auditory stimulation on the expression recognition. With ANOVA analysis of variance, LSD-t test, paired t test, Pearson correlation analysis and other statistical analysis.Results:1. Visual, auditory stimulation and stimulation of emotion(1)Visual stimuli arouse the emotions:T test showed that, before and after the positive and negative visual stimulus state anxiety (S-AI) score, valence (P) score differences were significant difference (p<0.05), arousal positive vision group (A) also statistically significant score between before and after the experiment, the control group no significant difference in emotional value the difference; LSD-t test, positive and negative visual stimulation group and control group, the state anxiety (S-AI) score, valence (P) difference was significant (p<0.05) score before and after, in addition, positive visual stimulation group and control group in the wake of the difference (A), negative visual stimulus dominance group and the control group (D) between the difference has statistical difference (p<0.05)(2) The auditory stimuli arouse the emotions:T test showed that positive and negative, before and after auditory stimulation state anxiety (S-AI) score, valence (P) score differences were significant difference (p<0.05), while the control group before and after experimental emotion value have no significant difference; the difference LSD-t test, positive and negative auditory stimulation group and control group of state anxiety (S-AI) score, valence (P) difference was significant (p<0.05) score before and after, in addition, positive auditory stimulus arousal group and control groups (A), the difference between the negative auditory stimulus dominance group and control groups (D) and arousal (A) the difference is significant (p<0.05).(3) Visual/auditory stimulation of emotional arousal effect:Before and after stimulation of t test, positive and negative visual and auditory stimuli, state anxiety (S-AI) score, valence (P) score differences were significant difference (p<0.05), and negative hearing group and negative visual group state anxiety (S-AI) variation, is hearing group and positive vision group state anxiety (S-AI), valence (P) variation difference was significant (p<0.05).2. Visual, auditory stimulation on the expression recognition and comparison(1) Visual stimulation effect on the micro expression recognition:LSD-t test, positive vision group and negative visual group, between negative visual group and control group, between positive vision group and the control group, micro expression recognition score difference were statistically significant (p<0.05).(2) Auditory stimulation on the expression recognition:LSD-t test, between positive group and negative group of hearing, between positive group of hearing and control group, there were statistical significance of expression recognition ability score differences (p<0.05), negative hearing group and control group, micro expression recognition no statistically significant differences in scores of visual/auditory stimulation.(3)Compared to the micro expression recognition effect:LSD-t test, between negative visual group and negative auditory group, between positive vision group and positive auditory group, micro expression recognition ability score differences were not statistically significant (p>0.05).3.Related studies, visual, auditory stimulation of emotional arousal effect is found, the value of changes in pleasantness was negatively correlated with psychoticism (r=-0.236), audio-visual stimulation of emotional arousal and coping style have no correlation, correlation and trait anxiety state anxiety change value (r=-0.339).Conclusions:(1) Visual, auditory stimulation of emotional arousal effect is remarkable, its role through the state anxiety (S-AI) score, valence (P) were measured. Comparison of difference and negative stimulus, it is visual, auditory stimulation arousal (A) changes significantly, while the negative visual, auditory stimulation dominance (D) changes more significantly. Comparison of visual, auditory stimulation of emotional arousal, the visual stimulus of emotional arousal is more significant than hearing.(2) Visual, auditory stimulation leads to emotional arousal state have influence on the micro expression recognition, positive emotions can improve the correct rate of facial expression recognition, negative emotions can reduce the accuracy of micro expression recognition. There was no significant difference in positive visual/auditory stimuli, negative visual/auditory stimuli micro expression recognition correct rate.(3)The visual, auditory stimuli emotional arousal correlated negatively effect and psychoticism, trait anxiety.
