AP PSYCHOLOGY

Detailed explanation-1: -This is called an Electo-occulograph (EOG) . Participants were woken (by a doorbell) at various times during the night, asked to describe their dream if they were having one, then returned to sleep.

Detailed explanation-2: -Sampling technique: Opportunity sampling. Our body follows two types of sleep: REM (rapid eye movement) sleep and nREM (non-rapid eye movement) sleep.

Detailed explanation-3: -From the study by Dement and Kleitman (sleep and dreams): Name the technique used to measure brain activity. The technique used to measure brain activity was an EOG. Identify one reason for using this technique to measure brain activity. An EOG is an objective measure, meaning that the EOG is unbiased.

Detailed explanation-4: -Aserinsky and Kleitman (1955) were first to use an EEG (a machine that detects the activity of nerve muscles) to investigate sleeping and dreaming. They found that humans have several sleep stages during the night, which alternate from REM (rapid eye movement) to NREM (non-rapid eye movement).

Detailed explanation-5: -What did Dement and Kleitman conclude about the relationship between dream content and eye movement? The self report method was used in this study to recall dream content. In each of the hypothesis they were awoken and asked to self report their dreams into a tape recorder.
