Do men pay better attention than women?

Background The primary aim of this study was to assess if there was a sex difference in reaction time.Methods Young males and females were tested for sustained attention and reaction time (i.e. Psychomotor Vigilance Test or PVT). Data is expressed as the mean and standard deviation. An unpaired t-test was used to determine if significant differences existed between males and females.Results Males were significantly different vis-a-vis height, weight, and percentage of body fat (Table 1). Furthermore, males demonstrated a faster reaction time than females (Figure 1).Conclusions Males demonstrate a faster reaction time than females as assessed by the PVT.
