Lecture #7- Situation influences Flashcards
What is behaviorism ?
Anything an organism does can be considered a behavior.
Thorndike’s law of effect?
What was the cat in the box experiment?
3pts
- Hungry cat in a box with a bunch of levers, figuring out which one leads to food
- Cat learns to associate pressing the lever with food: stimulus response bond (S-R bond)
- The consequences of a behavior determine whether the behavior is repeated
What is classical conditioning ? Give an example.
2pts
- Environmental/unconditioned stimulus is paired with a new/neutral stimulus to elicit the unconditioned response
- Pavlov’s dog salivation at the sound of the bell
What is operant conditioning?
Give an example.
2pts
- Strengthening or weakening of a behavior depending on it’s consequence.
- Cause and effect: cat pushing the lever to obtain food
This is the most relevant type of conditioning for most human behaviors.
Operant or classical conditioning?
Operant conditoning
What is a reinforcement? What is positive vs negative?
3pts
Reinforcement: Event that follows a behavior, increasing the likelihood of that behavior occurring in the future
Positive: adding something (not necessarily nice)
Negative: removing something
What is punishment?
- An event that follows a behavior, decreasing the likelihood of that behavior occurring in the future.
Positive reinforcement, negative reinforcement vs negative punishment, positive punishment?
- Praising a child for cleaning up.
- Because you studied hard all evening, I’ll do your chores for you tonight
- Roll up the cars window to get rid of the annoying wind on the highway
- Publicly shaming
- Getting a fine
- Taking away a child’s toy when they hit someone else
- Positive reinforcement
- Negative reinforcement
- Negative reinforcement
- Positive punishment
- Negative punishment
- Negative punishment
Schedules of reinforcement:
What is a continuous vs partial schedule?
In a partial schedule what is fixed, variable, interval and ratio?
Continuous: the behavior is reinforcement every time it occurs (eating, smoking)
Partial: the behavior is reinforced only some of the time
–> Fixed: behavior is reinforced on a predictable schedule
–> Variable: behavior is reinforced randomly or unpredictably
–> Ratio: based on the number of times the behavior occurs (how)
–> Interval: behavior is reinforced on a time interval (when)
Fixed interval, fixed ratio, variable interval or variable ratio?
- Every tenth cup is free. Every bag of leaves is 5 dollars.
- Random gifts from grandma, pellets falling into a cage after random amounts of time
- Allowance every Sunday, 20 dollars an hour, feeding cats at a consistent time
- Each instance of the behaviour has a chance to cause the reward. Slot machines. Trying to get a ‘drop’ in a videogame.
- Fixed ratio
- Variable interval
- Fixed interval
- Variable ratio
Which reinforcement schedule is the most motivating?
What are some examples of this.
Variable ratio reinforcement
- Ex- gambling, fishing, games, playing sports
What is the drive theory?
Drive is an aversive or uncomfortable state: When drive is high, the organism is motivated to engage in behaviors that reduce drive (biological needs are unmet)
What is Hull’s drive theory?
5pts
- Biological needs ignite a non-specific ‘drive’
- Habits are a learned behavior and they emerge because they were rewarded in the past
- Behavior = Drive x Habit
- Used multiplication because if either is 0, it won’t happen
- You need to have a learned response (habit) and a motivation to carry out the response (drive)
What was the criticism of Hull’s Drive Theory?
3pts
- Lack of evidence for “non-specific drive”
- Only biological needs were explained not psychological motives
- not all behaviors are linked to a reduction in drive
The tendency for the presence of others to improve task performance is known as…
The tendency for the presence of others to impair task performance is known as…
Give examples.
- Social facilitation
–> Triplett did the first empirical study of social psychology- asking kids to reel in a fishing line when alone or competing with another child - Social inhibition
–> easy to do alone, but then when around others we choke or fumble the task
