Dement and Klietman (methods) Flashcards
1
Q
What was the research method?
A
- Lab experiment
- Data collected via an observation
- Objective measures used (EEG/EOG)
- Self report measures (ppts spoke into a tape recorder)
2
Q
What were the 3 aims of the study?
A
- To investigate whether dream recall differs between REM and NREM stages of sleep
- To investigate whether there is a postive correlation between subjective estimates of dream duration and the length of the REM period before waking.
- To investiagte whether eye movement patterns related to dream content.

Q
- To investiagte whether dream recall differs between REM and NREM stages of sleep. Research design?
A
- Repeated measures design
- IV= Whether the ppts was woken up in REM/NREM sleep
- DV= Whether they recalled a dream or not
4
Q
2.To investigate whether there is a postive correlation between subjective estimates of dream duration and the length of the REM period before waking. Research design
A
- Repeated measures design
- IV= Whether ppts were woken after 5/15 mins after REM
- DV= Number of correct and incorrect estimations
- Correlational analysis= REM duration x number of words in a dream narrative
5
Q
To investigate eye movement patterns related to dream content. Research design.
A
- Quasi experiment (as the eye movement pattern was not manipulated by reseachers)
6
Q
How much ppts were in the sample?
A
- 9 ppts (adults)
7
Q
Describe the sample
A
- 7 males
- 2 females
- Overall: 5 ppts were studied intensively. 4 were used to confirm these results.
8
Q
What materials were used?
A
- Sleep lab (EEG/EOG)
- Electrodes (each ppts had 2+ electodes placed near their eyes and 2 or 3 placed on their scalp)
- Door bell (to wake ppts)
- Tape recorder next to bed (to record dream recall)
9
Q
What is the main aim of the study?
A
To investigate dreaming in a objective way by looking at the relationships between eye movements in sleep and dreaming.
