Term
|
Definition
| CS of interest becomes a signal for the absence of the US |
|
|
Term
|
Definition
| any situation developing new relationship between stimulus that will become the CS and the US |
|
|
Term
|
Definition
| 2 sensory stimuli that will on their own produce an orienting response |
|
|
Term
|
Definition
| involves sensory conditioning phase and first order conditioning phase |
|
|
Term
| standard conditioned inhibition procedure |
|
Definition
| analogous to a situation in which something is introduced that prevents the outcome that would otherwise occur |
|
|
Term
|
Definition
| interference with conditioning that is produced by repeated exposures to the conditioned stimulus before conditioning begins |
|
|
Term
|
Definition
| CS is presented after US has occured |
|
|
Term
|
Definition
| CS is paired with US on some trials and another CS is presented without the US on other trials. Second CS may acquire inhibition |
|
|
Term
| Conditioned Inhibitor (CS-) |
|
Definition
| CS that evokes inhibition; i.e. one that supresses size of CR that would otherwise be elicited by a second CS |
|
|
Term
| Appetitive counter conditioning |
|
Definition
| CR is appetitive (most people infer it as being a good response) |
|
|
Term
| Aversive Counter Conditioning |
|
Definition
| have appetitive stimulus as CS with an aversive US |
|
|
Term
| Negative CS/US Contingency |
|
Definition
| CS and US occur at random. Cannot predict that when one will happen so will the other. Begin to realize that when one occurs the other doesn't. CS- becomes an inhibitor to the US |
|
|
Term
| What are three ways to measure the conditioned response? |
|
Definition
1. conditioned response latency
2. CS alone test
3. magnitude of CR to determine strength |
|
|
Term
| Conditioned response latency |
|
Definition
| time until CR occurs after CS begins |
|
|
Term
|
Definition
| measure response to CS after we believe subject learned association well. Measure of response not contaminated with US and UR. |
|
|
Term
| magnitude of CR to determine strength |
|
Definition
| ex. volume of saliva produced |
|
|
Term
| Explicitly unpaired control group |
|
Definition
| present same 2 stimuli to control group that you present to experimental group, but explicitly unpair them (far apart, random order) |
|
|
Term
|
Definition
| looks like behavior change due to classical conditioning but change is due to sensitization |
|
|
Term
| What are 4 factors that impact the effectiveness of the CS and US? |
|
Definition
1. novelty
2. intensity
3. contiguity
4. relevance |
|
|
Term
|
Definition
| new stimuli likely to produce faster conditioning |
|
|
Term
|
Definition
| make stimuli intense enough so that they are salient - they stand out from the background |
|
|
Term
|
Definition
| closer in time and space, more likely to be associated |
|
|
Term
|
Definition
| Internal CS more easily associated with internal US. External CS more easily |
|
|
Term
|
Definition
| CS becomes a signal for the impending presentation of the US |
|
|
Term
|
Definition
| take trained inhibitor and pair it with a new conditioned exciter. If you see a conditioned response then the CS- is not a real inhibitor |
|
|
Term
|
Definition
| interference with conditioning produced by repeated exposures to the conditioned stimulus before conditioning begins |
|
|
Term
|
Definition
| test procedure that identifies a stimulus as a conditioned inhibitor if it is slower than a comparison stimulus to acquire an association when it is paired with a US. |
|
|
Term
|
Definition
| breaking the association between CS and US |
|
|
Term
|
Definition
| reappearance, after passage of time, of a response that had previously undergone extinction. |
|
|
Term
|
Definition
| novel stimulus disrupts situation and subject reacts to CS+ |
|
|
Term
|
Definition
| whichever is stronger will sway you in terms of expectation. If both equally strong, don't respond to either. |
|
|
Term
|
Definition
| 0 CR if CS+ and CS- are equally strong |
|
|
Term
|
Definition
| Initially novel stimulus is a distractor but it turns into a CS-. Prevent the CS+ alone and CR will return |
|
|
Term
|
Definition
| Overreaction due to expectation of a more intense US. Eventually turns into a compound inhibitor |
|
|
Term
| CS+ and Novel stimulus/US |
|
Definition
| New stimulus unimportant. CS+ carrying association |
|
|
Term
|
Definition
| all learning is blocked for novel stimulus by CS+ |
|
|
Term
| CS- and novel stimulus/US |
|
Definition
| not going to see CR on 1st trial because not expecting a US on first trial. Eventually see CR because expecting US when two stimuli paired together |
|
|
Term
|
Definition
| true CR beyond what you could train in other procedure |
|
|
Term
|
Definition
| Initial overexpectation but normal US leads to normal CR. Upon separation, devaluation in associative strength - each one alone produces less of CR |
