When the US (food) does not follow the CS (tone), CR (salivation) begins to decrease and eventually causes extinctionII. Spontaneous Recoverya. After a rest period, the CR (salivation) spontaneously recovers, but if the CS (tone) persists without food (US), the CR becomes extinct againIII. Unconditioned Responsea. An unlearned, automatic behavior that is built-in to our nervous systemi. Salivating at the sight of foodii. Pulling away because of painiii. Nausea due to something rotteniv. Shivering due to coldThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.v. Sexual arousal when viewing naughty thingsIV. Stimulus Generalization & Discriminationa. Generalization: tendency to respond to a stimulus similar to the CS (fearful of all dogs after being bit by a pitbull)b. Discrimination: learned ability to distinguish between CS and other stimuli that do not signal an unconditioned stimulus (fearful of only pitbulls after being bit bya pitbull)V. Pavlov’s Understandinga. Pavlov and Watson thought the mind was not fit for the study of psychology. However, they underestimated the importance of:i. Cognitive processesii. Early thinking: mindless behavioriii. Later thinking: animals learn to anticipate the stimulusb. Pavlov’s legacyi. All animals can learn by CCii. Showed how a process can be studied objectivlyVI. Biological Predispositionsa. A biologically adaptive CS (taste) led to conditioningb. Humans develop classically or conditioned
