PSYC 1001 1st Edition Lecture 35 Outline of Last Lecture I. Nightmares (Con’t)II. Theories of DreamingIII. Chapter 7: Learninga. Learningb. Classical Conditioning Outline of Current Lecture I. Classical ConditioningII. Five Major Conditioning ProcessesCurrent LectureI. Classical Conditioninga. US= Unconditioned Stimulus: Naturally and automatically triggers a response.i. Ex.: Triggers salvation (Unconditioned response in the dog.)b. Unconditioned Response: Naturally occurring response of the US.i. US > URii. Conditioned Stimulus > Salvationc. Conditioned Stimulus: A neutral stimulus that after association with an unconditioned stimulus comes to trigger an excited response > signal that unconditioned stimulus is about to occur > meat is coming, prepare.d. Neutral Stimulus: Does not produce the conditioned response before training.e. Conditioned Response: Learned response through a previously neutral stimulus.i. Ex.: Testing: (CS) Tone > meat > slobber (CR)1. Tone > slobber (conditioned response)2. US > URMeat > Slobber(CS- Pavlov guesses this).ii. > What determines conditioning?1. Stimuli that stand out- Ex.: A new taste.2. Novel Stimuli.3. Intense stimuli- Ex.: Barking Dog.4. Timing of unconditioned stimulus and conditioned stimulus.These 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.f. Short-Delayed Conditioning: CS begins just before the US and the CS and US end together.i. Ex.: 1. CS= (Comes on before) BUT both end together. 2. USii. This is the most effective training.g. Backward Conditioning: Backward conditioning CS occurs after US.i. Ex.: 2. CS 1. USii. Backward conditioning seldom works.iii. CS cannot act as a signal for the US.II. Five Major Conditioning Processes:a. Acquisition: A phase in which a conditioned stimulus comes to evoke a conditioned response > Gradu.b. Extinction: Gradual weakening and disappearance of a conditioned response by presenting the conditioned stimulus repeatedly without the unconditioned stimulus.c. Spontaneous Recovery: Reappearance after a pause, of an extinguished conditioned response.d. Generalization: Tendency to respond in the same way to a stimulus similar to a conditioned stimulus.e. Discrimination: Learned ability to distinguish between a conditioned stimulus and other stimuli that do not signal an unconditioned
