The Impacts of Video Games on Cognitive Function and Cortisol Levels in Young Female Volunteers
Objective: The aim of the present study was to investigate the effect of Football video game on cortisol levels and cognitive performance of female participants.
Materials and Methods: Thirty two female participants took part in the football video game. To measure the amount of cortisol hormone, saliva samples were collected before and after the game and assessed by enzyme-linked immunosorbent assay (ELISA) kit. Cognitive and perceptive performances were analyzed using PASAT test. The cognitive indices were evaluated including general mental health, response speed, sustained attention, and mental fatigue.
Results: Our findings showed that salivary cortisol concentration significantly increased following playing the game. The results of PASAT test also showed that response speed sustained attention and mental health significantly increased in participants after the game in comparison with before that. In addition, the longest chain of wrong answers, index of mental fatigue, slightly decreased in volunteers after the game.
Conclusion: The present study indicated that video game can positively impact the hypothalamus-pituitary axis (HPA) axis and improved perceptual-cognitive functions of the volunteers.
