    define learning

    a change in an organism due to experience, which can affect the organism's behaiour.

    People learn at different what?

    rates

    What leads to learning

    repetition

    Can learning be measured?

    yes

    How can learning be demonstrated?

    through behaviour

    How does learning occur?

    in stops and starts

    When does learning occur?

    virtually in everything we do

    Who is the person behind classical conditioning?

    Ivan Pavlov

    What is the unconditioned stimulus (US) in classical conditioning?

    A stimulus that naturally and automatically triggers a response.

    What is the unconditioned response (UR) in classical conditioning?

    An unlearned, naturally occurring response to the unconditioned stimulus.

    What is the neutral stimulus (NS) in classical conditioning?

    A stimulus that initially produces no specific response.

    What is the conditioned stimulus (CS) in classical conditioning?

    A previously neutral stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response.

    What is the conditioned response (CR) in classical conditioning?

    A learned response to a previously neutral stimulus.

    What is the relationship between neutral stimulus (NS) and conditioned stimulus (CS)?

    The neutral stimulus becomes the conditioned stimulus after association with the unconditioned stimulus.

    What is the relationship between unconditioned response (UR) and conditioned response (CR)?

    The conditioned response is learned and is similar to the unconditioned response.

    Time

    can act as a conditioned stimulus

    Extinction

    Conditioned responses are unlearned just as easily as they are learned

    Spontaneous recovery

    the reappearance, after a pause, of an extinguished conditioned response

    Generalization

    responding similarly to a range of similar stimuli

    Discrimination

    Reacting differently to fairly similar stimuli.

    Who is behind operant conditioning?

    B.F. Skinner. He said that behaviour is the result of seeking rewards or avoiding punishments.

    Classical conditioning forms an association between

    two stimuli

    Operant conditioning forms an acossiation between a

    behaviour and a consequence

    Skinner box

    A small enclosure in which an animal can make a specific response that is systematically recorded while the consequences of the response are controlled.

    Four possible consequences to behaviour

    Something good can start or be presented Something bad can start or be presented Something Good can end or be taken away Something bad can end or be taken away

    Positive refers to something being

    added

    Negative refers to something being

    taken away

    positive reinforcement

    Increases behaviour by adding a (usually good) stimulus

    negative reinforcement

    Increases behaviour by removing a (usually bad) stimulus

    Punishers

    A punishment decreases behaviour typically by using unpleasent consequences

    Positive punishment

    The administration of a stimulus to decrease the probability of a behavior recurring. When a behaviour is followed by an aversive stimulus such as a shock, loud noise, or spanking.

    Negative punishment

    When a behaviour is followed by the removal of a favourable stimulus

    Stimulus types

    Something good = starts/supplied R+ Something good = ends/removed P- Something bad = starts/supplied P+ Something bad = ends/removed R-

    Why should consequences be immediate in order to be effective?

    to be more effective or clear to the behaviour

    What can happen if consequences for animals or very young children are not delivered immediately?

    they will be confused

    Which method is generally recognized as more successful in shaping behaviour?

    Reinforcers

    one reason why reinforcement is considered more effective than punishment

    it actively builds desired behaviors, while punishment often only suppresses unwanted ones

    What are some serious side effects associated with the use of punishment?

    risk of causing serious physical harm, inducing fear or hostility, and failure to learn the correct response in a particular situation.

    Primary reinforcers

    related to our basic biological functioning

    Secondary reinforcers

    stimuli that are originally neutral but become reinforcers through association with primary reinforcers

    Continous reinforcement

    Every responde is reinforced

    Intermittent reinforcement - fixed ratio schedule

    Reinforcement is delivered after a fixed number or respondes have been made

    Variable ratio schedule

    the number of responses rewuired for a reinforcer to be delivered, varies for each trial

    Fixed interval schedule

    Reinforcer is delivered after a fixed amout of time has elapsed

    Variable interval

    Reinforcer is delivered after an average amount of time has elapsed

    Define shaping

    gradually molding or training an organism to perform a specific response by reinforcing any responses that are similar to the desirable response

    Define chaining

    involves one response leading to the occurrence of another response. Most behaviours occur in chains

    Bribery vs. Reinforcement

    Bribery is paying before behaviour is delivered; reinforcement is paying after delivery.

    Overjustification effect (aka undermining effect)

    Giving someone an incentive to do something they already enjoy doing decreases their intrinsic motivation to do it.

    Observational learning

    learning by observing others

    Who is behind observational learning?

    Albert Bandura

    For observable learning to occur, four conditions must be met

    1- Attention: must be aware of the behaviours of those around you 2-Retention: must remember the behaviour you witnessed 3- Ability to reproduce the behaviour 4-Motivation: we are most likely to learn if the behaviour has been rewarded to the model

    Role models

    Everyone is or has been a role model at one time or another. It is IMPOSSIBLE to choose not to be one.
