Document Summary
Reflexive response to stimuli: reflex: existing connection between stimulus and response (first causes the second, reflexes: innate or learned. Stimulus associated with another (usually neutral) stimulus: neutral: causes no particular response. Unconditioned(/al) stimulus (us) reflex: unconditioned(/al) response (ur) Cs same time or right before us. If us, ur are strong, may need less pairings. Cs + us ur: 3. Cr similar to ur but cr less intense. Us ur, cs cr: 4. Higher-order conditioning: using a conditioned response as a now unconditioned response to condition a new response. Use experiences to represent reality? (not association in time and place: depends on past experiences. May not be slow, requiring many pairings (just 5-6 trials) Generalization: similar (not the same) stimuli produce similar response. Discrimination: responding differently to different stimuli. Extinction: cs appears repeatedly without us cr weakens, cr spontaneously recovers (next day, spont. Classical conditioning leaves permanent record in nervous system. Cs cr after paired with us that already creates ur.
