Sheet1 Page 1 Basic Processes of learning Short Term: How do you feel right now? Long Term: Thinking about consequences. Learning requires paying attention to details. You infer emotions, not see, via visual cues learning the cues. Procedural knowledge : the learning of a motor skill to perform an action (Proceduralized/automatized) Repeated over and over again becomes unconscious. Reflexes(Mediated via nervous system) Things we do at birth independent of experience Ex: Eye blink in response to air, fear of snakes is not innate(learned exp), Startle response surprise. Habituation effects: a decline in the magnitude of response, when the stimulus is repeated in succession. Learning Def n: Any process via which experience at one time can alter an individual s behavior, cognition, or emotion at a future Classical conditioning Ivan Pavlov(1849-1936) -Won Nobel Prize for digestion. - experiment with dog chewing meat Psychic secretion cues prior to meat being presented (Accidental discovery) Other accidental discoveries: 1. X Rays: Wilhelm Roentgen. 2. Vaccination process Dog Experiment. Bell(Condition stimulus) No Systematic response Food(Unconditioned st.) Salvation UCR Extinction The gradual decline in responding when presented with the CS alone. Important terms: Generalization: When dog responds to a similar stimulus. Discrimination training: Can abolish generalization effects. What is being learned in classical conditioning? Two theories The S-R (Stimulus-Response) view --Perfect ex. Of behaviorism at its best --Pure behavior --Pavlov X subscribe to this view. The S-S (Stimulus-Stimulus) views. --Key diff. -Emphasis on mental representations --Classical conditioning as learned expectancy Haejihs psych notes: - you donht habituate to everything, such as gagging. *Habituation is a gradual decline in response to hUCSh -- after a hspontaneous recoveryh the response might increase a bit. --Pavlovhs preferred view --doesnht exactly apply to amebas

Then presented to a new stimulus. if the old stimulus is presented again , SS view(cause of expectations) : Doesn t know what to expect after new stimulus. Sexual arousal --sex/sexual imagery Pleasure Ex: Bud LITE ads Pleasure(feel good when people see products) Operant conditioning How is it diff. from classical? 1.Timing --Operant - AFTER. --Classical conditioning directly involves automatic reflexes, operant X. Operant C. Figures 1. E.L. Thorndike 2. B.F. Skinner Thorndike --Law of effect: responses that produce satisfying effect in a particular situation become more likely to occur in that situation, v --Puzzle Box: inhibition on actions that cats always do B.F. Skinner --Key term: Positive reinforcer for any behavior x , any event that increase the probability that the organism emits that r e --There is no such thing as free will respond to environment via reinforcement.
