Dement and Klietman (Procedures)

Question 1

Summarise the procedure simply

Answer 1

1. Introduction/ set up phase
2. Research question 1
3. Research question 2
4. Research questiion 3

Question 2

Describe the introduction phase

Answer 2

• The pptts were told to not drink caffine or alchol before the study
• The ppts were told to arrrive at the lab before their normal bedtime
• The ppts slept in a dark quite room
• Ppts were fitted with electrodes. 2+ near their eyes and 2 or 3 on their scalp. The wires were gathered into a ponytail and fed into the experimeters room
• The EEG ran continoulsy throughout the night
• Ppts always returned to sleep in 5 minutes

Question 3

Why were the wires gathered into a ponytail?

Answer 3

To allow ppts to move freely and prevent entanglement

Question 4

The EGG ran continously throughout the night…

Answer 4

At speeds of 3 or 6mm per seconds

Question 5

Pptts were not told….

Answer 5

• Their EGG pattern
• Whether their eyes were moving

Question 6

Research question 1

Answer 6

• ppts were either woken from REM or NREM sleep (not told which)
• Whether they would be woken up during REM/NREM was decided in different ways for different people
• Random number table= Ppts were woken according to a randoms table. (PM/KC)
• Random groups= In groups of 3 REM/NREM (DN)
• Deception= Telling the ppts they would be be awoken in REM but actually in NREM/ REM randomly (WD)
• On the researchers whim= (IR)
• After be woken up ppts stated whether they had a dream or not into the recorder. Describe the content.
• The experimenter would occatioanly enter the room to ask further questions

Question 7

Research question 2

Answer 7

• Ppts were either woken 5 or 15 mins after REM sleep
• They were woken up tp estimate the lenth of their dream (5/15 mins could choose longer periods
• The content of their dreams and length of teh dream narrative (words) were correlated with teh duration of REM
• Initially ppts would be woken up after a variety of REM durations and asked to estimate the duration of dream (too hard for ppts)

Question 8

Research question 3

Answer 8

• Ptts were woken as soon as 1/4 patterns of eye movements had occured for a minute
• They were asked what they had been dreaming about (self report)
• Eye movments were detected using electrodes around the eyes (EOG)
• Comparison EEG records were taken from ppts who were asked to watch distant close up activity
