What is a significant effect of sleep on cognitive function?

  1. Decreased ability to concentrate

  2. Increase in basal metabolic rate

  3. Transfer of memory from short-term to long-term memory

  4. Weakened immune system

The correct answer is: Transfer of memory from short-term to long-term memory

One significant effect of sleep on cognitive function is the transfer of memory from short-term to long-term memory. During sleep, particularly during the rapid eye movement (REM) and slow-wave sleep phases, the brain processes information from the day, consolidating new knowledge and experiences into more stable memories. This process of memory consolidation is critical for learning, problem-solving, and overall cognitive performance. Sleep facilitates the integration of new information with existing knowledge, allowing for improved recall and increased efficiency in retrieving information later. Without adequate sleep, this consolidation process can be disrupted, leading to difficulties in learning and memory retention. Thus, the relationship between sleep and cognitive function highlights the crucial role of restorative sleep in maintaining optimal mental performance.
