Chapter 10 The Learning Perspective Flashcards
Classical conditioning (Pavlovian conditioning)
*reactions could be acquired by associating one stimulus with another- Russian scientist Ivan Pavlov
Reflex
- existing connections between a stimulus and a response, such that the first causes the second
- Unconditioned stimulus and it causes unconditional response
- The stimulus in the reflex must become associated in time and place with another stimulus.
- The second stimulus is usually (though not always) neutral at first.
- It causes no particular response beyond being noticed.
- There are no special requirements for this stimulus.
First stage: situation before conditioning
- Only the reflex exists- a stimulus causing a response
- Unconditioned/unconditional stimulus (US): the stimulus
- Unconditioned/Unconditional response (UR): response
- Unconditional: no special condition is required for the response to occur
Second stage: conditioning
- Neutral stimulus occurs along with, or slightly before, the US.
- Conditioned/conditional stimulus (CS): neutral stimulus
- Stimulus that’s becoming conditioned
- A response occurs in its presence only under a specific condition: that the US is there, as well.
- When the US comes, the UR follows automatically, reflexively.
When the US and the CS are paired frequently, something gradually starts to change
*The CS starts to acquire the ability to produce a response of its own: conditioned response (CR)
*The CR is often very similar to the UR- look identical in some cases, except that the CR is less intense
*If the UR has an unpleasant quality, so will the CR. If the UR has a pleasant quality, so will the CR.
*Ex: Person in the restaurant (US) -> sexual arousal (UR); Background of the restaurant (CSs) -> Conditioned sexual response (CR)
-Present CS without US and see if there is a reaction
Yes -> conditioned
No -> not conditioned
High-order conditioning
- The more frequently the CS is paired with the US, the more likely conditioning will occur.
- CS-CR combination acts just like any other reflex
- Ex: Background of the restaurant such as music can be used to condition that arousal to other things; the music can condition a particular photo in the place where you listen the music
Generalization
- responding in a similar way to similar-but-not-identical stimuli
Discrimination
*responding differntly to different stimuli
Extinction
- CRs do weaken
- When a CS appears repeatedly without the US
- Spontaneous recovery
- Classical conditioning leaves a permanent record in the nervous system, and that its effects can be muted but not erased
Classical Conditioning and Attitudes
- You develop attitudes through classical conditioning
- People acquire emotional responses to attitude objects exactly that way
- Neutral stimulus (CS) -> emotional reaction (CR); Stimulus (US) -> emotional reaction (UR)
- If the attitude object is paired with an emotion-arousing stimulus, it comes to evoke the emotion itself. This response, then, is the basis for an attitude.
- Razran (1940)
- Slogans and free lunch, inhaling noxious odors, sitting in a neutral setting
- Walther (2002)
- Photos of neutral persons with liked or disliked persons -> positive and negative attitudes
- Higher-order conditioning
- Have not shown whether attitudes are usually acquired this way
- Events arouse emotions -> conditioning
- Preferences are important aspects of personality, conditioning seems an important contributor to personality
Emotional Conditioning
- classical conditioning in which the CRs are emotional reactions
- Emotional reactions to properties such as colors
- Andrew Elliot
- -Color red evokes negative emotions in academic contexts
- -Red induced avoidance motivation -> emotional conditioning
- People’s likes and dislikes- all the preferences that help define personality- develop through conditioning.
- Different people have different patterns of emotional arousal
- Different people also experience the same event from the perspective of their unique “histories”
- Children from the same family experience the family differently
- Different patterns of likes and dislikes -> unqiureness of personality
Instrumental conditioning/operant conditioning
- Active
- Follows the Law of Effet
- Determines habit hierarchy
The Law of Effect
- If a behavior is followed by a better (more satisfying) state of affairs, the behavior is more likely to be done again later in a similar situation.
- If a behavior is followed by a worse (less satisfying) state of affairs, the behavior is less likely to be done again later.
- Linking an action, an outcome, and a change in the likelihood of future action law of effect deduced by E.L. *Thorndike more than a century ago
- Accounts for regularities in behavior
- Some acts come to occur with great regularity, other don’t
Habit hierarchy
- as outcomes are experienced after various behaviors
- Derives from prior conditioning
- Some responses are very likely (high on the hierarchy) because they’ve often been followed by more satisfying states of affairs
- Other are less likely (lower on the hierarchy)
- Form of the hierarchy shifts over time, as outcome patterns shift
- Habit Hierarchy can shift for another reason
- Every change in situation means a change in cues (discriminative stimuli)
- The cues suggest what behaviors are reinforced in that situation
- A change in cues rearranges the list of behavior probabilities
- Changing contextual cues can disrupt even very strong habits
Reinforcer
- strengthens the tendency to do the act that preceded it
- Can reduce biological needs or satisfy social desires (smile, acceptance)
- Some get their reinforcing quality indirectly (money)
- Primary reinforcer: diminishes a biological need
- Secondary reinforcer: reinforcing properties by association with a primary reinforcer through classical conditioning or by virtue of the fact that it can be used to get primary reinforcers
Punisher
- unpleasant outcomes
- Reduce tendency to do the behavior that came before them
- Controversy about how effective they are
- Can also be primary or secondary
- Some events are intrinsically aversive (pain)
- Others are aversive because of their associations with primary punishers
Positive Reinforcement
- getting something good
* The behavior that preceded it becomes more likely
Negative Reinforcement
*when something unpleasant is removed
Positive Punishment
*Adding something bad
Negative Punishment
*Taking away something good
