Detailed explanation-1: -Five of them were studied intensively while the data gathered from the other four was minimal. 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-2: -The conclusions that were reached by Dement and Kleitman have been replicated by many other researchers. However, there is one methodological issue that should be considered. In relation to the first research question, Dement and Kleitman conclude that dreaming takes place in REM rather then non-REM sleep.
Detailed explanation-3: -Dement and Kleitman: Both qualitative and quantitative data was gathered in this study and the final data includes both types. Quantitative data was known from the EEG, such as when a participant entered REM or NREM sleep and for how long a participant had been in a particular stage.
Detailed explanation-4: -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.
