A Study Of The Effects On Micro-expression Recognize Ability By Audio-visual Stimulation And Study Strategy

Objective(1) Discuss the effects of different audio-visual stimulations to the micro-expression recognition ability;(2) Discuss the effects of different study strategies to the micro-expression recognition ability.MethodsThis study is experimental studies, recruiting90volunteers include19boys,71girls. The first test will be randomly divided into positive stimuli group, negative stimuli and non-stimuli group, and then were randomly divided into three groups which are distributed practice group, mass practice group, and none-practice of the control group. At first:three groups watch positive/negative/neutral emotional movie clips in each, then compare the S-AI before/after scores and micro-expression recognition before/after measurement results to observe the influence between different audio-visual stimulation on the individual micro-expression recognition ability. Secondly, the three groups above-mentioned are respective randomly divided into distributed practice group, mass practice one and none-practice of the control group, explore the influence of different study strategies to consolidate the the micro-expression recognition ability. In addition, this paper also analyzed the correlative factor of micro-expression recognition. Statistical analysis was performed using the t-test, Pearson relevant, Spearman rank correlation and repeated measures ANOVA.Results1. Basic conditionThe study is an experimental study. Taking the way of recruiting volunteers, there are90volunteers recruited, including19boys and71girls.2. Audio-visual stimulation effect on the micro-expression recognition ability(1) Difference between tests’micro-expression recognition ability in different stimuli groups has statistically significant (F=3.310, P=0.042<0.05);(2) Further paired t-test found that there is statistical significance between positive stimuli group and negative one, but no statistical significances between none-practice group with distributed/mass practice ones(P>0.05);(3) The difference between pretest and posttest results of positive/negative/none-stimuli group has no statistically significant(P>0.05);3. Study strategy effect on the micro-expression recognition ability(1) The difference between distributed practice group, mass practice group and none-practice of the control groups’micro-expression recognition ability score was statistically significant, further paired t-test found that there is statistical significance between none-practice of the control groups and distributed/mass practice one, but no statistical significances between distributed practice group and mass practice group(P<0.05);(2) The difference between pretest and posttest results of distributed/mass practice group has no statistically significant, which means the results of micro-expression recognition ability are well keeped after review.4. Effects of audio-visual stimulation and study strategy on the micro-expression recognition ability(1) There is interaction between the three levels both of audio-visual stimulation and study strategy on the micro-expression recognition ability;(2) In the distributed practice situation, positive stimuli group and non-stimuli group has statistical significance (P=0.024). The micro-expression recognition ability score of positive stimuli group (M=78.57, SD=15.74) is better than non-stimuli group (M=57.52, SD=17.00)(3) In the positive stimuli situation, distributed practice group and non-practice group has statistical significance (P=0.006). The micro-expression recognition ability score of distributed practice group (M=78.57, SD=15.74) is better than non-practice group (M=42.86, SD=23.04)(4) In the negative stimuli situation, non-practice group and distributed/mess practice group have statistical significance (Pd=0.009, Pm=0.025). The micro-expression recognition ability score of mess practice group (M=68.57, SD=11.95)is better than the others(Md=57.52, SDd=17.00, Mn=57.14, SDn=14.29).4. Correlative factor of micro-expression recognition(1) Interpersonal trust has significant predictive power on the micro-expression recognition ability, and the explanationable variation rate is12.5%;(2) Achievement motivation and all factors of personality have non-significant predictive power on the micro-expression recognition ability.Conclusion(1) There is statistically significant between positive and negative group, but no statistically significant difference of pretest and posttest results of micro-expression recognition ability.(2) In terms of different study strategies (distributed, mass, and none), micro-expression recognition ability score of practice group and mass practice one kept well, and the difference between the two groups has no statistically significant, which means we can not differ which one is better. The difference between distributed/mass and none-practice group are statistically significant, means proper review can retain the score of micro-expression recognition ability.(3) There is interaction between the three levels both of audio-visual stimulation and study strategy on the micro-expression recognition ability. In the distributed practice situation, positive stimuli are the better choice than non-stimuli group. In the positive stimuli situation, distributed practice is better than non-practice. In the negative stimuli situation, mess practice is the best choice of the three.
