Unit 5 Operant Conditioning Sleep Stress Flashcards
Who created operant conditioning?
B.F. Skinner
Who originally discovered operant or instrumental conditioning?
E.L. Thorndyke
Explain the “Law of Effect” that instrumental and Operant Conditioning is based off of?
Law of Effect= Consequences shape behavior, you can condition a behavior through consequences
What effect do reinforcements have on behavior?
Reinforcements= Increase behavior
What effects do punishments have on behavior?
Punishments= decrease behavior
What did Skinner do that Thorndyke didn’t?
Researched the types of consequences and ways of using them to condition behavior
Define consequence
Whatever happens after a behavior
(Not necessarily bad)
Explain positive consequence
Adding something after a behavior
Explain negative consequence
Removing something after a behavior
Explain positive reinforcement
Adding something to increase behavior
Explain negative reinforcement
Removing something to increase behavior
Explain positive punishment
Adding something to decrease behavior
Explain negative punishment
Removing something to decrease behavior
Decode this example:
A woman is speeding and a police officer gave her a speeding ticket to reduce her speeding behavior. What is the consequence?
-Subject being conditioned= the woman
-Subjects behavior= speeding
-Operator conditioning the subjects behavior= police officer
-Operators method= adding a ticket to decrease behavior
-Type of consequence= positive punishment
According to researchers, most people respond the best to which type of consequence?
Reinforcement
Which type of consequence has been linked with increased risk of developing mental health issues?
Punishments
Who discovered “learned helplessness”?
Martin Seligman
Give an example of learned helplessness in humans
An abused child learns to accept all the punishments (passive victim mentality)
List 4 effects of receiving too much punishment on a regular basis (beyond learned helplessness)
1- low self-esteem
2- poor coping skills
3- high stress (leads to illnesses)
4- mental health conditions (depression, anxiety etc)
Define post-traumatic growth
Overcoming hardships can make you more resilient to future stressors
Give 6 examples of how to use punishment without harming someone
1- catch subject in the act and immediately punish
2- consistency
3- punishment that fits the crime
4- stay calm, punish with love not out of anger
5- discuss why you are trying to teach appropriate vs inappropriate behavior
6-give opportunity to display appropriate behavior so you can reinforce it
Define the scheduling term “fixed”
Known, set, established, given, doesn’t vary etc
Define the scheduling term “variable”
Unknown, not set, unestablished, not given, varies etc
Define the scheduling term “ratio”
A number
Define the scheduling term “interval”
Duration of time
Explain “fixed ratio” schedule of consequences/reinforcements
Reward after a set number of behaviors is displayed
Explain “fixed interval” schedule of consequences/reinforcements
Reward after a set duration of time has passed
Explain “variable ratio” schedule of consequences/reinforcements
Reward after an unknown number of behaviors
Explain “variable interval” schedule of consequences/reinforcements
Reward after an unknown duration of time
Explain “continuous” schedule of consequences/reinforcements
Reward after every behavior
Who discovered Classical conditioning?
Ivan Pavlov
Who discovered operant conditioning?
B. F. Skinner
Terms used in classical conditioning
Conditioned/unconditioned
Stimulus/response
Terms used in operant conditioning
Reinforcement/punishment
Positive/negative
When is classical conditioning done?
Prior to behavior, causes involuntary response
When is operant conditioning done?
After behavior, can’t cause involuntary behevior
Define circadian rhythm
A series of biological processes that occur over 24hrs and then repeat
What starts circadian rhythm of sleep?
The transduction of light waves into action potentials
What limbic system structure, and which specific part of that structure, notices the change in light for circadian rhythm process?
The suprachiasmatic nucleus within the hypothalamus
Which hindbrain structure does further processing in response to the change in light
The reticular formation
Which gland releases melatonin hormone
The pineal gland
What does melatonin do?
It’s the hormone that makes you drowsy
Explain the 4 steps of the circadian rhythm of sleep process
1) the sun sets/light decreases
2) the optic nerve converts light waves into electrical signals (transduction)
3) the suprachiasmatic nucleus within the hypothalamus process the change in light
4) the reticular formation sends the signal on to the pineal gland which releases melatonin to make you drowsy
Who created the Electroencephalogram?
Hans Berger
List each stage of sleep
1NREM
2NREM
3NREM
4NREM
5REM
What type of brain wave is seen in 1NREM sleep?
Alpha and theta waves
What type of brain wave is seen in 2NREM sleep?
Theta waves
What type of brain wave is seen in 3NREM sleep?
Theta and delta waves
What type of brain wave is seen during 4NREM
Delta waves
What type of brain waves are seem during REM sleep?
Beta/alpha-like waves
List the classification (light to deep) and at least 1 additional feature of 1NREM sleep
Very light sleep, hypnogogic hallucinations
List the classification (light to deep) and at least 1 additional feature of 2NREM sleep
Light sleep, sleep spindles and K-complexes
List the classification (light to deep) and at least 1 additional feature of 3NREM sleep
Deep sleep, slow rhythmic breathing
List the classification (light to deep) and at least 1 additional feature of 4NREM sleep
Very deep sleep, sleep walking, talking, bruxism etc
List the classification (light to deep) and at least 1 additional feature of REM sleep
Rapid eye movement sleep, sleep paralysis & dreams
What is hypnogogic hallucinations?
Faulty mental processing of what’s real/imaginary as you go in a d out of 1NREM sleep
What are sleep spindles?
Bursts of brain activity that occur in 2NREM
What are K-complexes?
Abrupt drop in brain activity as if in deepest sleep but you are in 2NREM
What is Sleep paralysis?
When your body isn’t able to move in REM sleep
Explain the progression of the stages of sleep over an eight-hour period
We go through all 5 stages repeatedly (usually around 4 times) each rotation takes about 2 hours
Explain the progression of the 1st rotation of sleep over an eight-hour period of sleep
1st rotation: We quickly go through 1NREM, 2NREM, & 3NREM (~15 mins in each) but when we go into 4NREM we stay for a long time (~55 min) and then go into 5REM (~20min)
Explain the progression of the 2nd rotation of sleep over an eight-hour period of sleep
2nd rotation: we quickly go through 1NREM, 2NREM, & 3NREM (~20 min in each) and then we go into 4NREM but not quite as deeply (~35 min) and then go into 5NREM (~25 min)
Explain the progression of the 3rd rotation of sleep over an eight-hour period of sleep
3rd rotation: we quickly go through 1NREM, 2NREM (~24 min each) then 3NREM for longer (~30 min) and maybe? Get into 4REM (~5 min) before 5REM (~40 min)
Explain the progression of the 4th rotation of sleep over an eight-hour period of sleep
4th: we quickly go through 1NREM, 2NREM (~30min each) then 3NREM (~5 min) and then go into 5REM the (~55 min) we don’t go into 4REM at all
During which hours of sleep are you getting the most deep sleep and the most REM sleep?
The first 4hrs of sleep we’re primarily in 4NREM and the second 4hrs of sleep we’re primarily in 5REM sleep
Which type of sleep are you primarily depriving yourself of when you don’t get enough sleep?
5REM
What can happen as a result of depriving yourself of REM sleep?
The REM rebound effect
Explain the REM rebound effect
When you take a nap or try to catch up on sleep you go into 5REM sleep (you barely spend any time in the NREM stages)
