Verified step by step guidance

1. Understand the concept of sleep debt: Sleep debt refers to the cumulative effect of not getting enough sleep over time, which can negatively impact various cognitive and emotional functions.
2. Recall the typical effects of increased sleep debt on the brain and behavior, such as reduced alertness, slower reaction times, impaired memory, and decreased emotional regulation.
3. Analyze each option in the context of sleep debt: Enhanced memory consolidation and improved reaction time are generally associated with adequate or increased sleep, not sleep deprivation.
4. Recognize that increased emotional stability is unlikely with sleep debt, as lack of sleep often leads to emotional instability or heightened emotional responses.
5. Conclude that impaired cognitive performance is a well-documented aftereffect of increased sleep debt, as it encompasses difficulties in attention, decision-making, and memory.
