Sample
How many participants were there in this experiment
9
What is the difference between NREM and REM
REM: Occurs when our eyes move rapidly and our brain is more active. NREM is the opposite, the eyes don't move rapidly and the brain is ultimately quieter.
Was reliability high or low in this experiment and why
It was high because it was a lab experiment which causes it to have a lot of controls
Dreams occurred during what state
REM state
All subjects showed REM sleep how many nights
Every Night
How many participants were male, how many participants were female
What type of Research method was conducted in this study
A laboratory experiment, but different methods were used to test each aim
This experiment uses both qualitative and quantitative data to collect it's research. Give 1 example for each used in the experiment
Quantitative data: Brain waves, eye movement patterns, and REM sleep duration was collected through the EEG and EOG. Qualitative data: the dream content that was collected
What type of dreams were occurring with Horizontal
2 people throwing tomatoes at each other.
Awakenings from NREM produced a dream recall of what percent
7%
How were the participants in this experiment identified (Hint: it was not by their gender)
By their initials
What is EOG and where are they placed
EOG traces eye movements during sleep. Uses electrodes placed around the eye region.
How is generalizability limited, in terms of gender
Although both genders are involved in the experiment, the sample size is too small
What type of dreams were occurring with Vertical
standing at the bottom of a tall cliff and operating a hoist.
Awakenings from REM produced a dream recall of what percent
79.6%
4 participants spent 1-2 nights in the lab. How many times were they woken up? (Hint: between what and what)
4-10 times
What is EEG and where is it placed
EEG traces cyclical changes that occur in brain activity during sleep. Electrodes are placed around the skull to analyze brain waves.
Explain how Nature vs. Nurture is used in this experiment (Hint: Both are involved)
Dream content relates to our experience, so it is a product of nurture. However, the ability to dream is a product of nature.
What type of dreams were occurring with Vertical and horizontal
talking to people standing close to them.
Waking participants under 8 minutes of completing their REM period resulted in how many dreams being recalled.
5/17
5 participants spent between 6-17 nights in the lab. Approximately how many times were they waken up (Hint: between what and what)?
50-77 times
Who was Aserinsky and what did he reveal
A student of Kleitman, he revealed that p's who were woken up from REM sleep were more likely to remember a vivid, visual dream than those woken up during NREM
How is validity exhibited
Because the details focused on dreaming, the definition of dream was operationalized, in addition the ability for the p's to guess was reduced because the answer choices were only between 5 and 15 minutes
What type of dreams were occurring with Little or no movement
watching something in the distance or staring at an object.
However, waking participants after 8 minutes resulted in how many dreams being recalled.
6/132
