according to research on the cognitive effects of meditation, which of the following statements is most accurate?
long - term practicing of meditation may result in structural brain changes.
meditation may relieve symptoms of schizophrenia.
meditation may temporarily impair cognitive abilities.
meditation is identical to hypnosis.

Explanation:

For the first question: Dreams typically occur during REM sleep, which begins around 90 minutes after falling asleep; waking at this time makes dream recall more likely.
For Question 8: Research shows long-term meditation can lead to structural brain changes (e.g., increased gray matter in areas linked to attention and emotion regulation). The other options are inaccurate: meditation is not proven to relieve schizophrenia symptoms, it generally enhances (not impairs) cognitive abilities, and it is distinct from hypnosis.

Answer:

1. 90 minutes
2. Long-term practicing of meditation may result in structural brain changes.
