Objective        To explore the effect of harmful factors on neurobehavioral abilities of crews in tank cabins.       Methods       With the computerized neurobehavioral evaluation system-Chinese third edition (NES-C

3

)

109 soldiers who worked in tank cabins (observation group) and 112 soldiers who worked in conditions without any tank contact (control group) were enrolled to test their neurobehavioral abilities.       Results       Compared with the control group

the ability indices of serial addition and subtraction

auditory simple reaction time

aim tracing and digit canceling significantly decreased in the observation group (P0.05

P0.01). The minimum of visual retention time and the average of auditory simple reaction

time of soldiers in the observation group were significantly higher than those in the control group (P0.01).       Conclusion       Harmful factors in tank cabins have certain adverse effects on neurobehavioral function of tank crews

such us intelligence

learning and memory

perception and psychomotor ability. It is necessary to carry out intervention measures in tank cabin environment to improve the fighting capacity of tank crews.
