Describe the various stages of sleep
What will be an ideal response?
As you begin sleeping, you are in Stage 1 sleep. Brain waves, as measured by EEG, are small and irregular with variable frequencies. This lasts only 2 minutes or so. Upon entering Stage 2 sleep, there are occasional bursts of brain activity in the EEG called sleep spindles. Approximately 50% of sleep is in Stage 2 . In Stages 3 and 4, large, slow delta waves begin to appear. In Stage 3, 50% or less of brain waves are delta; when the percentage increases past 50, you have moved into Stage 4 . Stages 3 and 4 are sometimes referred to as slow-wave sleep. These 4 stages are collectively known as NREM sleep. You then move back through the stages in reverse order.
After Stage 2 is reached, you move into Rapid Eye Movement (REM), or paradoxical, sleep. Here, your brain is active and you are likely to be dreaming. This process takes about 90 minutes, and you cycle through the stages four or five times in a typical
night.

What will be an ideal response?
When a study was conducted assessing the likelihood of subjects to administer electric shocks to other human beings, it was observed that:
a. men were more likely to respond with aggression against the experimenter when they were instructed to administer shocks that they did not want to give. b. women were more likely to do what they were told by the experimenter because they did not have a good understanding of the machinery that they were asked to manipulate. c. women were more likely than men to administer what they believed to be more painful shocks. d. men were more likely than women to administer what they believed to be more painful shocks.
