Objective To investigate effects of different working environment on the vigilance and attention of the ship crew.Methods The times of correct response of the ship crew at different posts to simultaneous sound-light reaction,progress in the sound-light reaction time,the time on targets and the time out of track of targets were detected by using attention distribution measuring instrument (EP707A) and attention focus measuring instrument (EP711).Results There were significant differences in attention focusing for the ship crew at different posts (F =3.78,P =0.006).Different working environment had significant effects on attention focusing of the ship crew with more than 3 years of service at sea.Conclusions The ship crew working in the electromechanical and ammunition departments had relatively poor attention focusing.Three to five years of service onboard the ship was an important episode,when attention focusing was affected or most likely to be affected.
