Attention To Functional Network Research Under Emotional Conflict Task Conditions

In order to explore the relationship among alert network, orienting network (invalid orienting, valid orienting) and the emotional executive network and discuss the two different modes that will have an impact on attentional networks,this study combines the space clues paradigm and emotional flanker paradigm and adopts 2 (alerting types:tone, no tone) x 3 (clue types:center clue, valid clue, invalid clue) x 2 (emotional valence:happy, fear) x 2 (flanker types:congruent, incongruent) multi-factored design.In the experiment 1, they made their decision based on facial expressions in emotional explicit task; in experiment 2, participants were instructed to response or inhibit their behavior according to the facial gender in implicit task.Experimental results show that happy emotional executive values was significantly larger in those trials without tone alerting stimuli compared with the trials where the alerting tone was presented in the explicit emotional processing tasks and the conditions of the central clue;fear emotional executive values was significantly larger in those trials without tone alerting stimuli compared with the trials where the alerting tone was presented under the conditions of the valid clue.In implicit emotional processing tasks, happy emotional executive values was significantly larger in those trials without tone alerting stimuli compared with the trials where the alerting tone was presented; fear emotional executive values was not affected by alerting types.Different emotional valence of target stimulus affect the executive control system, the value of the happy target stimulus was larger than the value of the fear target stimulus.Fear effective orienting values and fear executive values were significantly larger in explicit emotional processing tasks than those in implicit emotional processing tasks.Fear ineffective orienting values in implicit emotional processing tasks were significantly larger than those in explicit emotional processing tasks.The conclusions are that the alerting network produces a promoted effect on the happy executive network in explicit emotional processing tasks and the conditions of the central clue; the alerting network produces a promoted effect on the fear executive network under the conditions of the valid clue;the alerting network has no impact on the fear executive function in implicit emotional processing tasks and promotes happy executive network. The fear target stimulus is better to resolve the emotional conflict. The explicit emotional processing promotes the fear effective orientation and the fear ineffective orientation,which will inhibit the fear executive network.
