The Evaluation of Cognitive Control Ability Under the Variable Operation Conditions

Cognitive ability evaluation is the main content of pilot psychological selection. Most of the existing cognitive ability assessment is based on a single cognitive ability assessment under normal condition, which does not consider the fluctuation of cognitive ability under the variable operation conditions. In this study, lower body negative pressure bucket was used to simulate accelerated stress, and digital Stroop task was used to evaluate the individual's cognitive control ability. The results showed that the main effect of stimulus information type was significant (F = 22.96, P < 0.01), and the response time to conflict stimulus was significantly greater than that to consistent stimulus (P < 0.05). With the change of operation condition, the fluctuation of cognitive control ability is not completely consistent across subjects. The findings in the current study indicated that digital Stroop task can be applied as an assessment tool of cognitive control ability, and operation condition should be included as a variable in the evaluation of cognitive ability to comprehensively understand the level of individual cognitive ability.
