Chapter 6 Review A) Classical Conditioning: training a subject to have a response they usually have with a stimuli to a neutral stimuli 1. Unconditioned stimulus - Stimulus that has causes an automatic response - Example food 2. Conditioned stimulus - Stimulus that you are trying to teach a subject to have an unnatural response towards. - Example bell 3. Unconditioned response - Natural response - Example salivation towards food 4. Conditioned response - Unnatural response - Salivation towards bell 5. Trial - Pairing of Unconditioned stimulus to Conditioned Stimulus 6. Acquisition - Initial stage of learning 7. 3 types of classical conditioning - Simultaneous: CS and US begin & end together - Short-delayed: CS begins just before the UC and then they both end at the same time - Trace: CS begins and ends before you present US 8. Extinction - Response to stimuli goes away with time 9. Spontaneous recovery - When response has been extinct but randomly comes back 10. Stimulus generalization - Begin to group similar stimuli to the one that causes a response 11. Discrimination - Do not feel response to this stimulus because it is not the same as the stimuli that initially provoked response. 12. Higher order conditioning - CS is not US and new stimuli is presented as CS and now response is generated with just the new CS. 13. Taste Aversions - When your body creates a nauseous feeling towards a taste or smell as a survival mechanism. B) Operant Conditioning: training someone to change their behavior by using rewards and punishments 1. Law of effect - If a response in the presence of a stimulus leads to satisfying effects, the association between stimulus and response is strengthened. 2. Positive reinforcement - A positive response is followed by a positive stimuli - Trying to have them repeat their response 3. Negative reinforcement - A positive response is followed by removing a negative stimuli - Trying to have them repeat their response 4. Skinner box - Be familiar with the skinner box experiment 5. Shaping - Trying to get the desired response so you guide them to perform the response you are looking for 6. Extinction As reinforces stop so does the behavior 7. Discrimination - Cues that influence operant behavior by indicating the probable consequences of a response 8. Delayed reinforcement - Reinforcement that is not given immediately - Slower conditioning 9. Primary reinforcement - Biological reinforcement - Needs - Example: water, food, sex 10. Secondary reinforcement - Wants - Example: money, grades, praise - Those reinforcements that may be used to trade for something else can also be known as generalized reinforcers if they are being more specific. Example: money 11. Ratio schedules - Deals with how many times you decide to give a reinforcement - Fixed: giving a reinforcement after a fixed number or non-reinforced responses (exact) - Variable: giving a reinforcement after a variable number of nonreinforced responses (approximate) - Most resistant to extinction 12. Interval schedules - Deals with how much time between responses that you decide to give reinforcement - Fixed: reinforcing the first response that occurs after a fixed time interval has elapsed - Variable: giving the reinforcement for the first response after a variable time interval has elapsed. - 13. Continuous reinforcement - Continuously reinforcing the response 14. Intermittent reinforcement - Reinforcing sometimes 15. Punishment - Negative response is followed by a negative stimuli - Trying to stop the response from happening again - Most effective when punishment is delivered right after the behavior 16. Over justification effect - States how individuals will feel toward performing certain tasks is determined by whether they are intrinsically or extrinsically motivated to perform the task. - You first behaved in a particular way b/c you enjoyed it (intrinsic) but you believe you are doing it for the reward (extrinsic). If your extrinsic reward decreases you stop enjoying the behavior b/c you do not have something to justify it with. 17. Chaining: - Subjects who are taught a number of responses successively in order to get a reward 18. Premack principle - whichever of two activities is preferred can be used to reinforce the activity that is not preferred. Example: if Peter likes apples but does not like to practice for his piano lesson, his mother could use apples to reinforce practicing the piano. C) Observational Learning: being trained or taught by observing. Sometimes we observe someone taking part in operant conditioning and we mimic their actions 1. Attention - To learn through observation you must pay attention 2. Retention - Must store mental representation of what you’ve witnessed in your memory 3. Reproduction - Enacting a modeled response depends on your ability. (cannot mimic response if you do not have the ability to do so) 4. Motivation - Unlikely to produce response unless you are motivated. 5. feral children - a human child who has lived isolated from human contact from a very young age and has no experience of human care, social behavior, and human language D) Names 1. Ivan Pavlov - Classical conditioning - Known for his experiment 2. John Garcia - Taste aversions - Know the sheep and coyote experiment 3. John B. Watson - Little albert - Behaviorism - Nature vs nuture 4. Edward L. Thorndike - Law of effect: when a stimuli’s response causes a positive effect, there is a more likely chance that the individual will repeat the response. 5. B.F. Skinner - Operant conditioning - Skinner box 6. Breland - Instinctive drift 7. Albert Bandura - Claims that both classical and operant conditioning take place simultaneously in observational learning. - Bobo doll experiment: Study w/ doll: one study was adult playing w/ clown…either aggressively or nonaggresively, kids tend to imitate same sex role models 19. Published landmark research on media violence & aggression in 1963 E) Miscellaneous 1. Phobias - Irrational fear that you are classically conditioned to have 2. Instinctive drift - Animals and/or humans have a tendency to drift back to the behaviors that is within their instinct 3. Signal relations - environmental stimuli serve as signals and that some stimuli are better, or more dependable signals than others 4. Response-outcome relations - Response will be strengthened if you liked the outcome 5. Latent learning - Learning that is not apparent from behavior when it first occurs 6. Instinct - Ethologists would define this as genetically programmed action pattern 7. Token economy - A system of behavior modification based on the systematic positive reinforcement of target behavior. - - - The reinforcers are symbols or tokens that can be exchanged for other reinforces. Based on the principles of operant conditioning and can be situated within applied behavior analysis (behaviorism) Applied with children and adults
