Aim
1) Are different dream stages influential to dream recollection?
2) Does a dream last approximately as long as REM?
3) Does eye movement change the dream subject?
Method
Repeated Measures Design (Aim 1 + 2)
Self Reports (Aim 3)
Conducted in Lab
Brain Activity Measurement Device
Electroencephalogram (EEG)
Electrooculogram (EOG)
Sample Group Size
9 Participants - 7 Male, 9 Female
5 People Tested
4 People Control Group
Location
Laboratory
How were participants woken?
Loud Bell
What did participants do when they were woken?
Record Verbal Narrative of Dream
% of Dreams Recalled in REM
79.6%
% of Dreams Recalled in nREM
93.1% NO dream recall
Hypothesis
Does eye movement impact dream content?
How were participants asked to estimate dream length?
Take a guess: 5 or 15 minutes?
Accuracy of participants in estimating their dreams
5 minutes: 88%
15 minutes: 78%
Independent Variable
Participant awoken during REM or nREM
Dependent Variable
Dream Recall
Data Type Collected
Mixed (Qualitative and Quantitative)
Benefits of Lab Setting
Control Outside Noises
Strengths
- Lab
- Loud Bell
- No EEG knowledge (participants)
- Operationalized “Dream”
- Both Genders
- Reliable Data
Weaknesses
- Not Natural Environment
- Only 2 Females
- Altered Sleep Pattern Due to Alcohol/Caffeine Ban
- Deception
Validity & Reliability
Reliability could be impacted by gender imbalance and small sample size.
The experiment is able to be replicated due to the exact procedures
Ethical Issues
Deception through telling participant that they were in REM all night
Conclusion
Dreams are impacted by REM, having them mainly occur during REM periods later in the night
Examples of Dreams
Tomatoes being thrown; Climbing a ladder; Basketball; Pulling pulley; Driving a Car
Hey guys!
I see you
