Detailed explanation-1: -Dement and Kleitman’s research aimed to find objective methods to demonstrate a relationship between dream content and physiological indicators of dreaming. Specifically, they wanted to investigate: Does dream recall differ between REM and nREM stages of sleep.
Detailed explanation-2: -Weaknesses: Low ecological validity – the environment were participants were studied was artificial i.e. they slept in a laboratory with electrodes on their head and face and were woken up by a doorbell.
Detailed explanation-3: -Dement and Kleitman (1957) concluded that it was possible to objectively measure dreaming and that this would be useful in working out how other influences might affect dreaming. 1. This was strong evidence that REM sleep is dream sleep, which has been supported by subsequent research.
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.
