Abstract： It has been identified that physical exercise is able to enhance cognitive functions, attracting attention to the underlying brain mechanisms. The literature shows that the enhancing effects rely basically on two distinct mechanisms, on the microscale and macroscale levels, respectively. At the microscale level, physical exercise favored synaptogenesis and the survival of neurons through better nutrient supply and metabolism. At the macroscale level, physical exercise could enhance cognition through enlarging the volume of white and grey matter, and changing the brain activity and functional connectivity. Notably, multiple factors could influence the enhancing effects of physical exercise on cognition, such as individual differences, time, and the interaction between physical exercise and cognitive stimulations. These factors provide new directions to conduct deep and systematic investigations on the brain mechanisms of enhancing effects on the two levels.

Abstract： Construal Level Theory holds that the spatial and temporal difference affect the individual’s representation of events, leading to different levels of emotional intensity. According to the theory of psychological typhoon eye, with the increase of spatial distance, the emotional intensity of individuals becomes stronger, and those at the center of events become more calm. The study is based on Weibo and adopts the research method of big data. We select two fatal accidents of female passengers on DiDi ride-hailing service as research objects to analyze effects of psychological distance on negative emotions, in which psychological distance can be divided into two dimensions: temporal distance and spatial distance. The study found that the further away from the unethical event, the longer after the event, the higher intensity of negative emotions generated by individuals. "
