Flashcards in Dement & Klietmen 1990 Deck (9)
- longer & more vivid dreaming occurs in R.E.M. -People dream in real time. 5 min periods (45/51) & 15 min period (47/60) -eye movements match a dream content
What is the result of hypothesis 3?
Dream of two People throwing tomatoes at each other occurre in only mainly horizontal R.E.M. Sleep
Evaluation strengths ?
Theoretical - the research provides support for the idea that dreams can be studied in an objective way & opens up areas of research for effect of environmental stimuli on dreaming
Methodological -1) dreams may be recalled easier in R.E.M. Than non sleep because the latter is a deeper stage of sleep 2) the study used a limited sample , mostly men therefore showed a lack of generalisability
What was the aim of demet & Kleitmen (1957)?
To determine when dreaming occurs
What is the procedure ?
9 (7 males & 2 female )
R.E.M. Sleep is corelated with dreaming , duration estimate correlated & eye movement correlates with reported dream content
Procedure (5) ?
1) slept individually in quiet dark lab 2)electrodes were connected near yes to register eye movements & on scalp to measure brain waves. 3) subjects were awoken at various times during night by loud doorbell noise 4)immediately reported in recording device wether they had been dreaming and content of dream before any contact with the experimentaer to avoid bias 5) subjects were never told wether their eyes had been moving or not
