habituation vs sensitization
|
habituation: repeated stimulation leads to decrease response (snail poking)
sensitization: repeated stimulation leads to increase response (spiders) |
|
|
classical conditioning
|
pairing of a biological response to a new learned stimulus
|
|
|
- unconditioned stimulus
- conditioned stimulus - unconditioned response - conditioned response |
- US: the stimulus that normally elicits a response
- CS: a stimulus that normally does not stimulate the response but can through learning - UR: the response that occurs automatically to a certain stimulus without any learning involved - CR: the same response occurs to an unnatural stimulus that would not normally elicit the response. |
|
|
acquisition
|
a conditioned response is learned
|
|
|
extinction
|
through repeated presentation of the CS without the US leading to a decrease in the CR over time.
thus the CS and US become unpaired |
|
|
stimulus generalization
|
a new stimulus that is similar to the CS can elicit the CR!
(i.e. church bell stimulates lunch bell and makes you salivate) |
|
|
aversive conditioning
|
coupling an aversive behavior with a painful stimulus to decrease the behavior
pt learns to pair the behavior with the stimulus and stops it over time |
|
|
learned helplessness
|
when an animal is in a stressful situation and cannot escape, it becomes depressed.
basically there is a classical conditioning pairing between the stressor and the feeling of unable to escape animal becomes hopeless and apathetic (depressed) antidepressents can increase the length of time needed to get learned helplessness |
|
|
imprinting
|
tendency to make an association with the first thing you see.
|
|
|
operant conditioning
|
learning of a physical behavior through the consequences of the behavior
|
|
|
- positive reinforcement
- negative reinforcement - punishment - extinction |
- PR: a postive response to a behavior to increase it (give money)
- NR: behavior is increased to avoid negative consequence (avoid being yelled at) - punishment: give aversive stimulus to decrease unwanted behavior - extinction: withholding any response to suppress a learned behavior (timeout) |
