Classical Conditioning
- type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus
- Ivan Pavlov: Russian psychologist who stumbled onto conditioned responses while collecting data for the role of saliva in digestion
- Includes US, UR, CS, CR, extinction, spontaneous recovery, and stimulus generalization
Unconditioned Stimulus?
Unconditioned Response?
- Evokes a response without previous conditioning
- Typically a reflexive unlearned reaction to an unconditioned stimulus
- Conditioned and unconditioned response are usually the same
Conditioned Response?
- The learned reaction to a conditioned stimulus
- Ex: just seeing Marge in kitchen makes Homer salivate
Conditioned Stimulus?
- A stimulus that was previously neutral but has become paired or associated with an unconditioned stimulus
- It’s a learned stimulus
Extinction?
- Describes the gradual weakening or disappearance of a conditioned response
- Because you aren’t exposed to it as much, it’s just going away
- Ex: boyfriend location no longer associated with him
Spontaneous Recovery?
- The reappearance of an extinguished behavior
- Response/behavior comes about again
- Ex: older sibling starts to act like baby
What type of response was the dog’s response to the unconditioned stimulus (food)?
Unconditioned response
Stimulus Generalization?
-Occurs when an organism has a learned response to a specific stimulus and responds the same way to other stimuli that are similar to the original stimulus
What type of response was the dog’s response to the bell?
Conditioned response; salivating
Operant Conditioning
- A form of learning in which voluntary responses come to be controlled by their consequences
- B.F. Skinner: he was a behaviorist, but not as much as John B. Watson; responsible for operant conditioning
- Includes consequence (positive/negative reinforcement and positive/negative punishment) and shaping
Consequence?
- The outcome of a behavior
- Includes reinforcement and punishment
Reinforcement?
-Type of consequence that INCREASES the likelihood of an organism to reproduce that behavior again.
Punishment?
-Type of consequence that DECREASES the likelihood of an organism to reproduce that behavior again
Positive vs. Negative?
- Positive: something’s being added
- Negative: something’s being taken away
Positive Reinforcement?
- A response is strengthened at the presentation of a rewarding stimulus
- Something’s being added and increases likelihood of it happening again
Positive Punishment?
- A response is weakened at the presentation of an aversive stimulus
- Something’s being added & decreases likelihood of it happening again
- Ex: like spraying cat with water, so it stops doing something
Negative Reinforcement?
- A response is strengthened at the removal of an aversive stimulus
- Something’s being taken away & increases likelihood of it happening again
- Ex: being cold, so put on sweater
Negative Punishment?
- A response is weakened at the removal of a rewarding stimulus
- Something’s being taken away & decreases likelihood of it happening again
- Ex: taking away door for bad grades
Stella cleaned her house and then her mother gave her five dollars. Next week, Stella cleaned her house again. What type is this?
Positive Reinforcement.
Glen stayed out past curfew. The next day, Glen’s parents grounded him for two weeks. Next time Glen went out with his friends, he came home on time. What type is this?
Negative Punishment.
Shaping?
- The reinforcement of closer and closer approximations of a desired response
- She gave example of learning to ride bike
- Common Example: potty training
- Doesn’t have to be something physical (like candy); can just be praise
Observational Learning?
- Occurs when an organism’s response is influenced by the observation of others
- Albert Bandura’s discovery
- Ex: learning how to cook by watching mom
- Ex: parents involved with politics, so you may be more likely to join too
- Ex: kid sees aggressive behavior, so they’ll be more aggressive
The reappearance of a conditioned response after extinction and a period of rest is called?
-Spontaneous recovery
Jenna got straight A’s and then her mother gave her the week off from chores. Next semester, Jenna tried hard and got straight A’s again. What is this called?
-Negative reinforcement
