Factors affecting conditioning
Law of effect
Next time: cognitive approach
What are the factors that influence conditioning?
What is the difference between classical and instrumental conditioning?
How is behaviour maintained by its consequences?
- Talk about the cognitive approach as well.
Classical conditioning of LOVE?
Don Bryne: Reinforcement – affect model
Arousing stimulus --- positive feelings positive evaluation (like music)
Neutral stimulus (stranger) like the stranger
May and Hamilton
Female students listen to: negative (classical), neutral, positive (rock)
- Rated attractiveness of male photos
While rating the men and if they had positive music, |MEN WERE RATED HIGHER| but otherwise,
negative music decreased the rating
Acquistion curves: response strength
1) Latency (CS – CR)
The latency decreases; negatively accelerated.
Once you get used to the stimulus, you get used to it. You learn better first, later on, you just fine tune
2) Output measure: in the start, you don’t present much, but later on in life, and its still negatively
accelerated. Faster flattening out, better you learn Temporal Contiguity
1) Forward pairing
CS is presented before the UCS
2) Simultaneous pairing: presenting UCS and CS at the same time
3) Backward pairing: presenting the CS AFTER the UCS.
Which one is the best?
Forward pairing. This is because it serves as a cue. Interval should be 0.5 seconds.
Higher – order conditioning
- Pair primary CS with another neutral stimulus (secondary CS)
- Not very effective… CS-UCS bond is no longer reinforced
- The CR extinguishes
Higher order conditioning DOES NOT work classical model
- CS no longer paired with UCS
- Decrease in response strength
- CS loses cue Value.
Stronger the CS, it takes longer to forget it
1) Index of strength
2) CS-UCS bond not unlearned
“savings” & spontaneous recovery
