Other AbstractIn the daily life, people constantly experience a variety of life events, such stressors from the environment can trigger the body's stress response, mainly for the hypothalamic - pituitary - adrenal system (HPA axis) activation and secretion of glucocorticoids like cortisol, which then pass through the blood brain barrier into the prefrontal brain regions, thereby affecting executive functions. Executive function which locates in the prefrontal cortex consist of subcomponents such as task switch, working memory and response inhibition. In the moment when environmental stimuli increasingly diverse, job requirements increasingly turning complex, important practical significance lies upon it to carry out stress to study the impact of the prefrontal executive function. In particular, there is few studies being published on our new recruits’ executive function as a high-stress group.
In this study, we use the life events of enlisting and training of the recruits as the stressor and a starting point, choosing classic paradigms of behavioral experiments. Firstly we examined the relation between stress response and its coping factors and executive function; then multiple measurements had been taken during training procedure on their coping strategies, emotion regulation strategies, perceived social support and mental health as indicators to examine the initial coping effort on stress, we also hope to find a connection between execution functions and meantime mental health and furthermore it can be held as a proof that executive function play a mediating role between recruits’ stress and their executive function. Finally we try to establish a reliable variable relational model following the path of stressor to stress response to coping effort to executive functions to present and future mental health, and thus provide helpful references for the evaluation of new recruits in our country.
In this study, we find that stress may be the cause of many soldiers ‘impaired response inhibition ability and lack of positive coping strategies and emotion regulation strategies and inefficient perception of social support each serves as a mediator of this negative effect; Meanwhile, response inhibition ability correlated positively with the mental health condition, but not as a mediator between recruits’ stress and their mental health condition.
In summary, this study uses a combination of various approaches including scales and behavioral experiments, to examine the relationship between the recruits’ stress, their prefrontal executive function and mental health condition systematically. The study discovered the relationship between recruits’ stress and executive function with the existence of the effect of three intermediary variables, while executive function positively correlated with mental health condition but not as an intermediate link between recruits’ stress and mental health condition. Such findings suggest that the significance of the recruit soldiers’ executive functions under stress. In order to better understand the psychological situation of newly recruited soldiers, it provided useful reference for future evaluation of new recruits, and at the same time, strengthened the view of the existing relationship between stress and executive function.
