在青春期，与上学时间早有关的睡眠阶段延迟增加了白天的嗜睡，降低了精神运动表现。一些研究表明，性别对成人和儿童的精神运动表现有影响。男性的反应时间（RT）比女性快。本研究的目的是评估性别对青少年手掌精神运动警觉性任务（PVT）表现的影响。34名青少年（19名女孩，13 - 16岁）在巴西库里蒂巴的一所公立学校上早班，参与了这项研究。使用活动记录仪测量睡眠模式，并用卡罗林斯卡嗜睡量表（KSS）获取嗜睡数据。KSS和PVT分别于上午8点和11点采集。将性别作为一个因素，使用单因素方差分析对数据进行比较。方差分析表明，性别对睡眠模式和主观嗜睡没有影响；然而，性别对PVT表现的影响具有统计学意义。男孩的RT- pvt1: 345.51 ms, F = 6.08, P < 0.05; RT- pvt2: 343.30 ms, F = 6.35, P < 0.05)比女孩（RT- pvt1: 402.96; RT- pvt2: 415.70; lapses- pvt1: 16.33; lapses- pvt2: 17.80）更快，失误更少（lapses- pvt1: 8.71, F = 4.45, P < 0.05）。这些结果表明，已经在成人和儿童中报道的这种性别影响，在青少年中也可以观察到。在使用Palm PVT评估该年龄段的精神运动表现的研究中，应考虑到性别的影响。
During adolescence, the sleep phase delay associated with early school times increases daytime sleepiness and reduces psychomotor performance. Some studies have shown an effect of gender on psychomotor performance in adults and children. Males present faster reaction times (RT) compared with females. The aim of the present study was to evaluate the influence of gender on Palm psychomotor vigilance task (PVT) performance in adolescents. Thirty-four adolescents ( 19 girls, 13 to 16 years old) attending morning school classes of a public school in Curitiba, PR, Brazil, participated in the study. Sleep patterns were measured using actigraphy and sleepiness data were accessed with the Karolinska Sleepiness Scale (KSS). KSS and PVT measurements were collected at two times in the morning (8: 00 and 11: 00 h). The data were compared using one-way ANOVA, considering gender as a factor. ANOVA indicated that gender did not affect sleep patterns and subjective somnolence; however, a statistically significant effect of gender was detected for PVT performance. Boys presented faster RT (RT-PVT1: 345.51 ms, F = 6.08, P < 0.05; RT-PVT2: 343.30 ms, F = 6.35, P < 0.05) and fewer lapses (lapses-PVT1: 8.71, F = 4.45, P < 0.05; lapses-PVT2: 7.82, F = 7.06, P < 0.05) compared with girls (RT-PVT1: 402.96; RT-PVT2: 415.70; lapses-PVT1: 16.33; lapses-PVT2: 17.80). These results showed that this effect of gender, already reported in adults and children, is also observed in adolescents. The influence of gender should be taken into account in studies that use Palm PVT to evaluate psychomotor performance in this age range.
