Question Answer
PHYSIOLOGICAL Dement and Kleitman (1957) Sleep Aim: 1. Will people be more likely to report dreams if they are woken in REM than NREM. 2. Can people accurately estimate the duration of there dream? 3. Is the direction of eye movement during REM related to dream content?
PP's: Seven adult MALES and two adults FEMALES. Five pp's were studied intensively; Minimal data from the other four were collected in order to confirm the results of the first five.
Method: Lab experiment. pp's told to avoid alcohol and caffine and to report just before normal bedtime. pp's were woke throughout the night by a doorbell and asked to recall a dream if they had been dreaming. Equipment: Electrodes attached near the pp's eyes were connected to an EEG machine which measures brain electrical activity and the EOG measures eye movement.
D_K.jpg (image/jpg) ALL subjects were more likely to recall dreams when woken from REM. This gives us an answer to question 1. in the aim.
D_K2.jpg (image/jpg) Subjects were woken after either 5/15 mins of REM and asked if they had been dreaming for 5 or 15 mins. Results show that pp's were mostly accurate in their estimations.
D_K3.jpg (image/jpg) These results support the idea that eye movement is related to dream content which gives us an answer to question 3 of the aim.
1. People are more likely to report dreams if they are woken during periods of REM than NREM. 2. People can estimate the duration of dreaming to an extent. 3. The direction of eye movement during REM seems to be related to dream content. There are no real conclusions only that REM sleep IS connected to dreaming.
