Detailed explanation-1: -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-2: -Research Hypothesis There will be a positive correlation between the estimate of dream duration and REM period length. There will be a significant association between eye movement patterns and dream content.
Detailed explanation-3: -Strengths: High level of control – the researchers controlled many extraneous variables such as not drinking alcohol or caffeine before the experiment, waking up participants with the same doorbell sound and having participants in the same environment. This makes the results valid and reliable.
Detailed explanation-4: -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.
