Concepts are fundamental to our ability to THINK and make sense of the world Concepts influence memory o If something is inconsistent with a prototype, we are less likely to remember it o Slower to think about it Problem Solving Strategies 1. Trial and Error 2. Algorithms 3. Heuristics (intuition) 4. Insight Algorithms Algorithms exhaust all possibilities before arriving at a solution Computers use algorithms o S P L O Y Y C H O G o If we were to unscramble these letters to form a word using an algorithmic approach, we would face 907,200 possibilities Informal Reasoning The process of evaluating a conclusion, theory, or course of action on the basis of the believability of the evidence o Not necessarily based on the truth of the evidence Heuristics: Time-saving mental shortcuts used in reasoning o Steve lives in ATL. He’s shy, withdrawn, helpful, but with little interest in reality. Is he salesperson or librarian? Librarian o More salespeople than librarians in Atlanta according to statistics, but we judge probability of the event based on his description Representative Heuristic Conclusions about whether something belongs in a certain class are based on how similar it is to other items in that class o You ignore information about base rates o There are many more salespersons than male librarians o Conjunction fallacy Mistakenly categorize a person based on their description rather than statistics Which is more likely? If I go to the Middle east, which should I be more worried about? o Terrorist attack o Traffic accident Availability Heuristic The likelihood or an event or the correctness of a hypothesis is judged by how easy it is to think of that event or hypothesis o Misperceive low-likelihood events as high likelihood because you see or hear about them a lot o It comes to mind easily; its “available” in your mind Language The primary means through which we communicate our thoughts to others Phoneme: the smallest unit of sound that affects the meaning of speech Morphemes: the smallest unit of language that has meaning Words: units of language composed of one or more morphemes When do we learn language?
