Chapter 7 Flashcards
Habituation:
Decrease in the strength of response to a repeated stimulus
Sensitization:
Increase in the strength of response to a repeated stimuli
Classical Conditioning:
When an organism associates two stimuli such that one comes to produce a response that originally was produced only by the other stimulus
Learning:
Process by which experience produces a relatively enduring change in behaviour or capabilities
Acquisition:
Period during which association is being learned
Unconditioned stimulus:
Triggers a reflexive unconditioned response without prior learning
Unconditioned response:
Response triggered by unconditioned stimulus without prior learning
Conditioned stimulus:
Through association with UCS, comes to trigger a conditioned response similar to the original UCR
Conditioned response:
Response triggered by a conditioned stimulus
Extinction:
Weakening, and eventual cessation of a CR, of a caused by the presentation of the CS without the UCS
Spontaneous Recovery:
Reappearance of a previously extinguished CR after a rest period and without new learning trials.
Generalization:
Stimuli similar to initial CS triggers CR. This aids in survival. Ex: If an animal hears the rustling of a bush and is attacked by a predator, through stimulus generalization the animal develops an alarm response to a range of rustling sounds.
Discrimination:
CR occurs to one stimulus, but not to another. Allows organisms to discriminate differences between stimuli preventing unnecessary stress.
Higher order Conditioning:
When a neutral stimulus becomes a CS after it is paired with another CS. Usually, this higher order CS is weaker and extinguishes more rapidly that the original CS
Exposure Therapies:
Exposure to the fears stimulus without any UCS, allowing extinction to occur.
