learning & memory notes 10/10-10/14 ▯ Learning: ▯ Extinction & Spontaneous Recovery No longer pairing the CS with reward Sudden re-emergence of a previously learned CR ▯ Aspects of CC ▯ Generalization: Taking what you learned and applying it in a different situation. When to use the info. Giving a CR to stimuli that are similar to the CS More different the situation=performance goes down Ex: Studying for the exam and taking the exam ▯ Discrimination Learning When NOT to use the info. Learning to give the CR to only the CS and not to similar stimuli ▯ Long-Term Potentiation: A potential cellular form of learning. Belief that learning should involve some type of change in the brain Often studied in the Hippocampus ▯ Why the Hippocampus? 1. Brain region that is most important for declarative memory 2. Perfect neural experimental type ▯ What impairs learning? 1. Lack of sleep 2. Stress 3. Drugs 4. Alcohol 5. Damage to the Hippocampus Tetanus: Increased strength of the stimulus. Operant Learning: You do something to get something (good or bad) back. Law of Effect: Responses that produce desirable effects would be stamped into the individual. Reinforcer=liked Punishment=disliked ▯ Positive: Applied Ex: Spanking, Chores ▯ Negative: Removed Ex: taking away something that the individual enjoys ▯ Ratios of Reinforcement: How often do you get the reinforcement. 1. Fixed=Rewarded for predetermined number of responses. 2. Variable=Can’t predict the number of responses needed for reinforcement. 3. Fixed Interval=A known time needs to pass in order to receive the reinforcement. 4. Variable Interval=Time is unknown to receive the reinforcement. Higher Order Learning Hypothesis Testing: “Process of Elimination” Cognitive Maps: A mental representation of the world in your mind that you use to facilitate your behavior. Represent distance at some level Can create errors & distortion ▯ Imitation: Learn by watching or imitating someone else’s behavior. ▯ Memory: ▯ Memory: Evidence that learning has occurred. No unified operational definition ▯ 3 Main Components ▯ Encoding: Modification of information to by processed by the memory system. Like transduction Modified into action potentials “Learning” ▯ Storage: The retention of the material over time. Storing memory “Memory” ▯ Retrieval: Location and recovery of the memory when it is needed in the future. Memory is only useful if you can find it and use it “Get memory out” ▯ Types of Memory ▯ Recall: Retrieving information not currently in your consciousness. Ex: Short answer questions ▯ Recognition: Identifying items previously learned. Ex: Multiple choice questions ▯ Relearning: Learning something more quickly the second time through. ▯ Three Stages of Memory ▯ Sensory (iconic) memory: Memory at the level of the sense. Short in duration Ex: Sun spots in your eyes ▯ Working (short term) memory: Temporally graded memory. Memory you are currently using Stored often in chunks (capacity of 7 chunks) Most vulnerable ▯ Long-Term memory: Memory that lasts for long periods of time. Ex: Remembering your past teachers ▯ Efforts to Increase Processing ▯ Chunking: Packaging information together. ▯ Mnemonics: Something that helps you remember something Ex: Acronyms ▯ Hierarchies/Scripts: Sequence of events that often happen. Can produce false positives ▯ ▯
