Enhancement of cognitive index with computer game using Brain Signals and hormonal analysis: randomized controlled trial
nowadays, computer games play an important role on the cognitive and behavioral health of the community. The purpose of this research was to investigate the short-term effects of Flow Free® on the players' neurologic characteristics.
A total of 40 healthy male students aged 20 years and over were randomly divided in the control and experimental groups. All tests were performed before and after the game in experimental group. The tests performed only once in the control group without participating in the game following watching the game. Saliva samples were collected to measure cortisol and alpha amylase levels. Cognitive tests and electro-encephalography were performed. Data were analyzed using Wilcoxon signed ranked test
There was no significant difference between groups in demographic characteristics and pre-intervention measures (same as experimental participant without playing game). Post-tests showed no significant change in control group. In experimental group, PASAT results indicated a significant increase in mental health (P=0.037) and sustained attention (P=0.046); the changes in the concentration of alpha amylase (P=0.009) and salivary cortisol (P=0.01) after the game showed a significant increase compared to the pre-test. Also, an increase in the mean surface of the pattern of stress index (p=0.039) and attention index (P=0.048) were recorded. Post-test measures in experimental group were also significantly different from control group.
Flow Free®, as a stimulant of the central nervous system, imposed increased activity of the stress path and changes in brain signals. As a result, it strengthened the cognitive element of attention in the players after the game.
