- association between REM/Non-REM and dreaming
- positive correlation between subjective duration of dream and duration of REM
- REM is associated with dream context
- Controlled lab experiment (sleep lab)
- also correlation
- 7 males and 2 females (5 studied intensely)
- self select, ALL avoided coffee/alcohol throughout
- given time to get used to environment
- BUT REAL SAMPLE IS 351 AWAKENINGS (5.7 per night)
- 1st Aim: Repeated measures, IV = REM or Non-Rem, DV = dreaming?
- 2nd Aim: Repeated measures, IV= duration of REM (5/15 minutes) DV = can they guess time?
- tested individually, reported a little before bed time, asked to follow normal daily routines
- slept with electrodes attached to EEG/EOG
- 1st Aim: Some pp were woken up randomly, some 3 times in REM then 3 times in Non-REM, each time woken up by a doorbell, stated if they'd been dreaming into tape recorder
- 2nd Aim: Same procedure but woken up 5 or 15 minutes into REM, asked if they'd been dreaming and how long for?
- 3rd Aim: used EOG readings for 4 eye movements (vertical, horizontal, both, no movement), woken up and asked what they were dreaming about
- each pp. had distinct dreaming/sleep patterns, average REM = 20 minutes which occured every 90 minutes.
- If woken up in non-REM would quickly go back to sleep, if in REM wouldn't return to REM
- 1st Aim: in REM 152/191 dreams were recalled whereas in non-REM only 11/160 recalled, the…
