Abstract:
Objective:To investigate the influence of positive emotion induced by audio sensory on cognitive control.Methods:In the study, participants were divided into two groups, one completed the task with music which could induce positive emotion named as positive emotion group, and the other done task without music named as non-music group.Then the reaction time(RTs) and accuracy in AX-CPT(AX-continuous performance test) task and AX-CPT modification task in the two groups were analyzed through repeated measurement variance using SPSS 18.0.Results:In AX-CPT task, RTs results showed that the main effect of time interval was significant ( F(1, 58)=98.68, P<0.001, η2=0.63). The RTs of participants with 3 000 ms was longer than that with 1 000 ms, and the main effect between groups was edge significant ( F(1, 58)=3.79, P=0.05, η2=0.06). The RTs of positive music group was longer than non-music group; and the interaction between time interval and music potency was significant ( F(1, 58)=9.69, P<0.01, η2=0.01). In BX, the interaction between time interval and music potency was also significant( F(1, 58)=12.11, P<0.01, η2=0.17). When the time interval was 3 000 ms, RTs in the positive music group increased than that in non-music group in BX under AX-CPT task( F(1, 58)=5.09, P<0.05). When the time interval was 1 000 ms, there was no significant difference in RTs between the two groups( F(1, 58)=0.01, P=0.97). However, RTs in the positive music group decreased in AY in AX-CPT modification task than that in non-music group( F(1, 53)=4.12, P<0.05). Conclusion:The interference of cue stimulation decreased in positive emotion induced by music and decreased proactive control, but not stable.Always, it is influenced by metal fatigue and task experience.
