Learning Flashcards
Operant Conditioning
- a form of learning where responses (actions) are controlled by their consequences
What is classical conditioning?
- learning?
- Repeated exposure can alter subsequent effects
What is habituation? Examples? (TEXT)
Diminishing physiological or emotional response to a frequently repeated stimulus
I can only think of neurobio examples and this isn’t covered in slides so check the text for this one!
What is the Law of Effect? (thorndike’s findings)
- if a behavior (response) in a specific situation leads to satisfying effects, then that response is more likely to occur again in that situation
Acquisition
- the initial stage of learning in which UCS and CS are paired
- Closer pairings stronger
- Novel stimuli stronger than commonplace ones
What were thorndike’s findings?
- The law of effect
- if a behavior (response) in a specific situation leads to satisfying effects, then that response is more likely to occur again in that situation
Extinction
- the gradual weakening and disappearance of a conditioned response tendency
- CS (conditioned stimuli) presented without the UCS
Stimulus generalization
- occurs when an organism has learned a response to a specific stimulus, responds in the same way to the new stimulus that are similar to the original stimulus
Stimulus discrimination
- occurs when an organism that has learned a response to a specific stimulus does not respond in the same way to a new stimuli that is similar to the OG stimulus
what is spontaneous recovery?
- reappearance of an extinguished (extinct) response after a period of non-exposure to the CS
Renewal effect
- if a response is extinguished in a different environment than it was acquired, the extinguished response may reappear if the subject encounters the conditioned stimulus in the OG environment where acquisition took place
Higher order conditioning
- the conditioning of a second CS by pairing it with the OG CS without the OG UCS
- Dog food (UCS) + bell (CS1) + CLAP (CS2) — dog food (UCS)
What is positive and negative reinforcement and punishment (in terms of operant conditioning)
- Reinforcement is an event following a response (behavior) that increases tendency to repeat the response
- Positive or negative Reinforcement adds or takes away something to STRENGTHENS a response
- Punishment is an event following a response (behavior) that decreases tendency to repeat the response
- Positive or negative punishment adds or takes away something to WEAKEN a response (aka ruin it, taint it, make them not wanna do it again)
How do different reinforcement schedules relate to rate of responding and resistance to extinction?
Continual reinforcement (1:1 fixed ratio)
- *Intermittent reinforcement (not 1:1 ratio)**
- fixed = lower resistance to extinction
- Variable = higher resistance to extinction
- Ratio = higher response rates
- Interval = shorter intervals generate higher response rather OVERALL (long-Term)
- VR ideal for cramming, VI ideal for long term memory
- *almost guaranteed to be a question in this!!**
Applications of operant conditioning?
- Can involve learning of new actions
- Positive and negative reinforcement
- Punishment
