Task-specific sex differences in vigilance performance: subjective workload and boredom.

Participants (24 men, 24 women) were asked to perform either a spatial or temporal vigilance task. Task-related Boredom and NASA-Task Load Index scores were collected. The results replicate Dittmar, Warm, Dember, and Ricks' 1993 finding of task-specific sex differences in vigilance performance and subjective workload. The present study also showed task-specific sex differences for boredom ratings. These results suggest that two explanations may account for the sex differences. More accurate perceptual discriminations may account for some of the differences in performance; however, sex differences in perceived boredom may more likely be responsible for the task-specific sex differences in vigilance performance and subjective workload.
