Q

when does habituation happen?

A

Happens all the time (sitting in the classroom and the fan comes on to circulate the air – may notice at first but will adapt). You’ve habituated to the presence of that stimulation

A

a form of learning in which animals come to reasons to a previously neutral stimulus that is paired with another stimulus that elicits an automatic response

form associations

Q

what is Pavlov’s pioneering research?

A

investigating digestion

found that dogs would begin to salivate when they heard the footsteps of the feeders

The dogs began to drool in response to even hearing the footsteps of the people coming to feed them

Dogs associated the food with the stimulus which predicted the arrival

Physiology in the brain had this natural response

Q

what is acquisition?

A

learning phase during which a conditioned response is established

Q

what is extinction?

A

gradual reduction and eventual elimination of the conditioned response after the conditioned stimulus is presented repeatedly without the unconditioned stimulus

an active process, not merely “forgetting”. A form of learning

Q

what is stimulus generalization?

Q

generalization gradient

A

the more similar the stimulus is to the original CS, the stronger the response of the condition (CR) will be.

Q

what is higher-order conditioning?

A

developing a conditioned response to a conditioned stimulus by virtue of its association with another conditioned stimulus

Ex: Pair metronome (neutral) with food (UCS) –Metronome becomes CS that elicits salivation

Q

what is latent inhibition?

Study These Flashcards
A

difficult in establishing classical conditioning to a conditioned stimulus we’ve repeatedly experienced alone (without UCS)

24
Q

what is operant conditioning?

Study These Flashcards
A

Learning is controlled by the consequences of the organism’s behavior
- Response-consequence learning

25
examples of operant conditioning
Teaching a dog to lie down and roll over using food as a reward Fastening a seatbelt because the warning sound kept dinging
26
what is another term for operant conditioning?
also called instrumental conditioning
27
what is the law of effect?
if a stimulus followed by a behavior results in a reward, the stimulus is more likely to give rise to the behavior in the future - A response followed by satisfying consequences become more probable - A response that is followed by dissatisfying consequences become less probable
28
reinforcement
Outcome or consequence of a behavior that strengthens the probability of the behavior - Positive or negative
29
positive reinforcement
the presentation of a stimulus following a behaviour that strengthens the probability of the behavior - Appetitive stimulus is given to the organism
30
negative reinforcement
the removal of stimulus following a behavior that strengthens the probability of the behavior an aversive stimulus is removed
31
example of positive reinforcement
For example, giving a child a piece of candy after they complete their homework serves as positive reinforcement, increasing the likelihood that the child will do their homework in the future.
32
example of negative reinforcement
For example, turning off a loud alarm when someone buckles their seatbelt serves as negative reinforcement, increasing the likelihood that the person will buckle their seatbelt in the future.
33
what is punishment?
Outcome or consequence of a behaviour that weakens the probability of the behaviour
34
positive punishment
administering a stimulus that the organism wants to avoid Administering an aversive stimulus
35
negative punishment
Removing a stimulus that the organism wants to experience Removal of an appetitive stimulus
36
when is punishment most effective?
works best when delivered consistently and immediately following undesired behaviour
37
what is typically less effective than reinforcement in changing behavior?
punishment. only tells the organism what not to do, not what it should do. Punishment may encourage subversive behaviour Punishment may provide a model for undesired behaviour
38
What is a discriminative stimulus
a stimulus that is associated with the presence of reinforcement Sets the occasion for a response
39
how does discriminative stimulus work?
Cues the organism to perform a behavior because it has been reinforced in the presence of the cue
40
example of the discriminative stimulus
Grandparents -- child asks for Candy
41
difference between discriminative stimulus and stimulus discrimination!
a discriminative stimulus is a stimulus associated with the presence of reinforcement Stimulus discrimination is the weakened CR to a CS that differ from the original CS
42
Acquisition
learning phase in which an operant response is established
43
Extinction
The gradual reduction and eventual elimination of an operant response when reinforcement for that response is no longer presented
44
spontaneous recovery
the re-emergence of an extinguished operant response after a delay following extinction
45
stimulus discrimination
the organism displays a less pronounced response to stimuli that differ from the original discriminative stimulus
46
stimulus generalizatoin
the organism shows an increased probability of responding in the presence of stimuli to the original discriminative stimulus
47
what is schedule reinforcement?
pattern of reinforcing a bhaviour
48
what is continuous reinforcement?
the behavior is reinforced every time it occurs, resulting in faster learning, but also faster extinction than other forms of reinforcement
49
partial reinforcement
occasional reinforcement of a behavior, resulting in slower extinction than if the behavior had been reinforced continually
50
what are the two dimensions of reinforcement?
1. Consistency of reinforcement: Fixed or variable 2. Basis of reinforcement: Ratio or interval
51
what is a fixed ratio schedule?
a pattern in which reinforcement is provided following a regular number of responses
52
Variable Ratio Schedule:
a pattern in which reinforcement is provided after a specific number of responses on average, with the number of responses varying randomly.
53
Fixed Interval Schedule:
a pattern in which reinforcement is provided for a response at least once following a specified time interval
54
Variable Interval Schedule:
a pattern in which reinforcement is provided at least once during an average time interval, with the interval varying randomly
55
Shaping by Successive Approximations:
Conditioning a target behavior by progressively reinforcing behaviors that successively approximate the target behavior
56
primary reinforcer
item or outcome that naturally increase the target behaviour
57
secondary reinforcer
neutral objects that become associated with a primary reinforcer
