a pattern of brain waves in response to induced stress with different cognitive readiness

Introduction: many unpredictable situations require the use of cognitive and emotional resources, but stress prevents adaptation to the situation and cognitive readiness claims to create this adaptation. therefore, the aim of this research is to compare the brain wave patterns with different cognitive readiness in two situations with and without stress. method: the present research is of a causal-comparative that the statistical population included military personnel, who volunteered to participate in the research. the participants included 42 people who were placed in two groups of low and high cognitive readiness. the level of cognitive readiness of all people was done using situation simulation and virtual reality. the electroencephalography of subjects was recorded in two situations. data were analyzed using the mancova test. results: brain waves have significant differences between the two groups, and the intensity of the waves in the group with low cognitive readiness is more than the other group, which shows brain activity to react to stress in the group with low cognitive readiness is more than the other group (p<0.01). conclusion: physiological and neurological indicators can be considered important for military applications. this is because finding physiological characteristics with sufficient accuracy can be reliable evidence for selecting military personnel or checking the effectiveness of psychological.
