How does prolonged sleep deprivation affect human volunteers?

It impairs concentration.

European swifts sleep:

According to the activation-synthesis hypothesis, it should be possible to predict (with better than chance accuracy) the content of a person's dreams if we know what information about the person?

stimuli currently acting on the body and areas of spontaneous brain activity

One study found that a nap that included ____ sleep enhanced performance on certain kinds of creative problem solving.

REM

According to the activation-synthesis hypothesis, what do dreams reflect?

The brain's attempt to make sense of spontaneous neural activity

If we compare either different species or different ages, what trend emerges?

Which of the following is NOT true regarding hibernation and sleep?

They increase body temperature.

Dreams begin with arousing stimuli, whether generated from the external or internal environment, according to which hypothesis/theory?

Which hypothesis/theory suggests that the primary motor cortex is suppressed so arousal during sleep cannot lead to action?

a clinico-anatomical hypothesis

Which of the following shows a decreased need for sleep?

Compared to REM, research suggests that NREM is:

important for strengthening memories of lists of words

Which of the following would most likely have the highest total amount of REM sleep?

infant human

Young adults deprived of a nightÕs sleep show deficits on ____ tasks.

memory

Research suggests that REM is:

most important for strengthening memories of motor skills.

For which species does REM sleep compose the largest percentage of total sleep?

species that get a great deal of sleep

If you were awakened every time you entered REM sleep for a few days, and then were permitted to sleep without interruptions, you would:

spend about 50 percent more time in REM sleep than usual

During dreaming, which of the following area or areas continue to be highly active?

the hypothalamus, amygdala, and other emotional areas

Patients with damage to ____ report no dreams.
