Effects of sleep deprivation on sustained attention in young adults
Keywords:Sleepiness, Attention, Toulouse-PiÃ©ron Test.
BACKGROUND: Sleep deprivation is common nowadays and considering that attention is important to our dailyÂ activities, it is important to compare the effects of sleep deprivation on sustained attention.
AIM: This study investigated the effects of sleep deprivation on sustained attention in young adults.
METHOD: Sixteen adults were evaluated both after a normal and after one night of sleep deprivation. SustainedÂ attention was assessed through the Tolouse-PiÃ©ron Test (TPT), measuring the number of correct responses (CR),Â omissions, and attention coefficient, at first, fifth and tenth minutes of the test.
RESULTS: Results revealed a reduction in the number of CR in the fifth compared to the first minute but only inÂ the post-test session. The number of omissions increased in the fifth compared to the first minute in the post sleepÂ deprivation. Attention coefficient decreased in the fifth and tenth compared to the first minute.
CONCLUSION: Sleep deprivation deteriorates sustained attention, especially when adults are required to maintainÂ attention for long periods.
