Microgravity impairs spatial orientation and early object recognition but leaves logic reasoning less affected. Attention-dependent tasks and long-term memory show performance declines during space flight.

Area of Science:

  • Neuroscience
  • Space Medicine
  • Human Physiology

Context:

  • Space flight research is crucial for understanding human adaptation to altered gravity.
  • Studies on microgravity's cognitive effects are limited but growing.
  • Simulated weightlessness provides valuable insights into spaceflight conditions.

Purpose:

  • To review recent advancements in understanding microgravity's impact on cognitive functions.
  • To identify specific cognitive domains affected by reduced gravity.
  • To synthesize findings on both impaired and less-affected cognitive abilities.

Summary:

  • Microgravity impairs spatial orientation, motion perception, and early object recognition.
  • Muscle coordination and movement capabilities are reduced.
