Q

Unconditioned Stimulus- US or UCS

Q

Conditioned response- CR

A
  • behavior that is considered a reflec paired with CS

- salivating at the sound of the bell because it is associated with food

22
Q

Learned responses in everyday life

A

-associating songs with ads and products

23
Q

Taste aversion

A
  • Garcia effect
  • losing your taste for a food after having a bad experience with it
  • SEAS chicken tacos
24
Q

John Garcia

A
  • Garcia effect/taste aversion

- intial exposure to flavored water followed by a toxic reaction to radiation made rats averse to the water

25
Q

Stimulus discrimination

A
  • a response to only the specific stimulus that has been conditioned
  • dog only responds to a platic bowl and not a metal one when conditioned with a plastic bowl
26
Q

Stimulus generalization

A
  • a response to another stimulus that is similar to the orginal conditioned stimulus
  • dog responds with salivation regardless of the material of the bowl it was originally conditioned
27
Q

John B. Watson

A
  • Little albert experiment
  • classical conditioning and phobias
  • left psychology to work in advertising
28
Q

Higher order conditoning

A
  • second order conditioning
  • classical conditioning with an extra conditoned stimulus
  • a new neutral stimulus becomes associated with the conditioned stimulus
29
Q

Extinction

A
  • a process that leads to the gradual weakening and eventual disappearance of the conditioned response to the conditioned stimulus by presenting the CS repeatedly without pairing it with the UCS
  • pairing without reinforcement of the US will break the association
30
Q

Spontaneous recovery

A

-a stimulus response that recurs without any obvious reason after a stimulus response has been extinguished

31
Q

B.F. Skinner

A
  • every behavior has consequence

- operant conditioning

32
Q

Operant Conditioning

A

-a type of learning in which voluntary behavior is modified by subsequent consequences

33
Q

Consequences

A

-a result or effect of an action or condition

34
Q

Instrumental conditioning

A
  • another name for operant conditioning

- Skinnerian conditioning

35
Q

Edward Thorndike

A
  • law of effect

- puzzle box

36
Q

Law of effect

A
  • Edward Thorndike

- any behavior followed by pleasant consequences is likely to be repeated

37
Q

Trial and error

A

-attempting various methods until finding one that is effective

38
Q

Superstitious behaviors

A

-actions that are only incidentally tied to good results

39
Q

Reinforcing stimulus (reinforcement)

A
  • a consequence that increases the likelihood of a behavior occuring again
  • hug, payment, praise
40
Q

Punishing stimulus (punishment)

A
  • a consequence that decreases the likelihood of a behavior occuring again
  • slap, phone confiscated, traffic ticket
41
Q

Primary reinforcement

A
  • reinforcing stimulus that satisfies a primal, biological need
  • food, drink, pleasure
42
Q

Secondary reinforcers

A
  • conditioned reinforcement
  • learned through association
  • money is not inherently valuable but it buys things that are
43
Q

Positive reinforcement

A

-adding pleasant stimulus to increase behavior

44
Q

Positive punishment

A

-adding an aversive stimulus to reduce behavior

45
Q

Negative reinforcement

A

-removing an aversive stimulus to increase behavior

46
Q

Negative punishment

A

-removing pleasant stimulus to reduce behavior

47
Q

Escape conditioning

A
  • operant conditioning that occurs when an organism learns to perform an operation to terminate an ongoing, aversive stimulus
  • jumping over a barrier to avoid getting shocked by an electric floor
48
Q

Schedules of reinforcement

A
  • Skinner developed a series of principles called the schedules of reinforcement
  • These systematic consequences reinforced behavior that was increasingly close to the desired behavior.
  • Rewarding correct steps to ensure that the behavior occurs.
49
Q

Avoidance conditioning

A
  • similar to escape conditioning but includes a CS and is preventative in nature
  • a tone (CS) sounding every time before a rat gets shocked, causing the rat to move when the tone goes off to avoid getting shocked
50
Q

Operant conditioning chamber

A
  • Skinner box
  • designed to train research animals
  • placed hungry animals in the chamber using their existing behaviors as a basis for training them to do specific tasks
51
Q

Continuous reinforcement

A
  • occurs when every instance of a desired behavior that occurs is reinforced
  • rats getting food every time they press a lever
52
Q

Partial (intermittent) reinforcement

A
  • not reinforcing a response every time. This results in a slower acquisition of a response but much greater resistance to extinction.
  • ratio schedules, interval schedules, variable reinforcement, fixed reinforcement
