AI Article Synopsis
- Total sleep deprivation (TSD) means not sleeping for a long time, and it can make it hard to pay attention and respond quickly.
- In a study, participants did a test where sometimes they had to stop themselves from responding, and they did this after being awake for over 34 hours.
- Even though their response times were slower, they could still stop themselves from responding correctly when they needed to, showing that they could manage their focus even while really tired.
Article Abstract
Total sleep deprivation (TSD) is known to impair sustained attention. However, previously reported effects of TSD on response inhibition are mixed. We administered a "stop-signal" variation of the psychomotor vigilance test, which included 25% of trials requiring withholding of a response to assess response inhibition alongside sustained attention. Participants completed the task at baseline and after 34.5 h of wakefulness. Accuracy was not reduced during TSD. However, response times were significantly slower. A speed/accuracy trade-off allowed participants to effectively withhold responses on inhibition trials and conferred resilience of inhibitory control during TSD under conditions of relatively low time pressure.
