19
Q
Classical conditioning
A
The process by which a neutral stimulus acquires the capacity to elicit a conditioned response through association with an unconditioned stimulus that naturally elicits a similar response
20
Q

21
Q
Unconditioned stimulus (us)
A
Causes natural , innate response not associated with previous learning
22
Q
Unconditioned response (ur)
A
Response that US causes
23
Q
Conditioned stimulus (cs)
A
An initially neutral stimulus that comes to elicit a conditioned response after being paired with an unconditioned stimulus several times
24
Conditioned response (cr)
A response that is elicited by a conditioned stimulus. Occurs after the CS has been associated with the US . Is usually similar to the UR
25
Acquisition
Initial learning stage in classical conditioning in which an association between a neutral stimulus and be unconditioned stimulus takes place
26
Discrimination
Tendency to respond differently to 2 or more similar stimuli
27
Operant conditioning
Process by which a response becomes more likely to occur or less so , depending on its consequences
28
Edward thorndike
Puzzle box:
- hungry cat in box
- 1st trials, cat tried several behaviors, scratching.
- pulling string allows escape
- law of effect : responses with satisfying consequences and are more likely to be repeated and vice versa
29
B.F skinner
- behaviorist
- behavior is followed by consequence
- the consequence modifies the tendency to repeat behavior in future
30
Operant chamber
Using Thorndikes law of effect as a starting point , skinner developed the operant chamber, or Skinner box , to study operant conditioning
31
Reinforcement
Process by which a stimulus or even strengthens or increases the probability of the response/ behaviors it follows
32
Punishment
Process by which a stimulus or even decreases or reduces the probability of the response/behavior that it follows
33
Primary reinforcers
Inherently reinforcing and typically satisfying a physiological need
-food
34
Secondary reinforcers
stimuli that have acquired reinforcing properties through association with primary reinforcers
- money
35
Positive reinforcement
Response is followed by the presentation of a pleasant stimulus causing an increase in the response/ behavior
- response more Likely occur
36
Negative reinforcement
Response is followed by the removal of an unpleasant stimulus causing an increase in the response/behavior
-response more likely occur
37
Primary punishes
Stimuli that are inherently punishing
| - electric shock or pain
38
Secondary punishes
Stimuli that have acquired punishing properties through association with other punishers
- demerits or bad grades
39
Positive punishment
Response is followed by the presentation of an unpleasant stimulus causing a decrease in the response / behavior
- given something you don't want
40
Negative punishment
Response is followed by the removal of a pleasant stimulus causing a decrease in the response/ behavior
- something you want is taken away
41
Continuos reinforcement
Desired response each time it occurs
| - behavior always reinforced
42
Intermittent (partial) reinforcement
Reinforces a response only part of the time
| - though this result in slower acquisition in the beginning . It shows greater resistance to extinction later on
43
Shaping
