Test 2 Psy 421 Flashcards
Habituation
Repeatedly increase the US which decreases the UR
How is the phone call at night conditioned to bad news
The contingency percentage is high
What 2 things influence conditioning
Intensity and species
Overshadowing
Failure of a stimulus that is part of a compound stimulus to become a CS.
Latent inhibition
The failure of a CR to appear as a result of prior presentation of the CS in the absence of the US.
5 variables that affect Pavlovian conditioning
- Pairing the CS and the US
- Contingency
- Contiguity/ISI
- Stimulus features/overshadowing
- Prior experience with CS and US/ latent inhibition and blocking
Blocking
Failure of an NS to become a CR when it is part of a compound stimulus that is an effective CR
Rescorla-Wagner model
There is a limit to the amount of learning of conditioning that can occur, that the limit depends on characteristics of the CS and US, each successive pairing produces less learning
Preparatory response theory
The CR prepares the organism for the US
5 traits of stimulus substitution theory
- Weaker
- Slower to develop
- More variable
- Qualitative difference (chewing rather than just salivating)
- Sometimes the CR is the opposite as the UR
Withdrawal and tolerance
Tolerance- same amount of drug will not produce the same effect
Withdrawal- opposite of the main drug effect
Body compensatory
Preparatory response for OD
