Myers PSYCHOLOGY,Chapter 10 Thinking and Language,Thinking,Cognition mental activities associated with thinking, knowing, remembering, and communicating Cognitive Psychologists study these mental activities concept formation problem solving decision making judgment formation,Thinking,Concept mental grouping of similar objects, events, ideas, or people Prototype mental image or best example of a category matching new items to the prototype provides a quick and easy method for including items in a category (as when comparing feathered creatures to a prototypical bird, such as a robin),Thinking,Algorithm methodical, logical rule or procedure that guarantees solving a particular problem contrasts with the usually speedierbut also more error-prone-use of heuristics,Thinking,Heuristic simple thinking strategy that often allows us to make judgments and solve problems efficiently usually speedier than algorithms more error-prone than algorithms,Thinking,Unscramble S P L O Y O C H Y G Algorithm all 907,208 combinations Heuristic throw out all YY combinations other heuristics?,Thinking,Insight sudden and often novel realization of the solution to a problem contrasts with strategy-based solutions Confirmation Bias tendency to search for information that confirms ones preconceptions Fixation inability to see a problem from a new perspective impediment to problem solving,The Matchstick Problem,How would you arrange six matches to form four equilateral triangles?,The Three-Jugs Problem,Using jugs A, B, and C, with the capacities shown, how would you measure out the volumes indicated?,The Candle-Mounting Problem,Using these materials, how would you mount the candle on a bulletin board?,Thinking,Mental Set tendency to approach a problem in a particular way especially a way that has been successful in the past but may or may not be helpful in solving a new problem,Thinking,Functional Fixedness tendency to think of things only in terms of their usual functions impediment to problem solving,The Matchstick Problem,Solution to the matchstick problem,The Three-Jugs Problem,Solution: a) All seven problems can be solved by the equation shown in (a): B - A - 2C = desired volume. b) But simpler solutions exist for problems 6 and 7, such as A - C for problem 6.,The Candle-Mounting Problem,Solving this problem requires recognizing that a box need not always serve as a container,Heuristics,Representativeness Heuristic judging the likelihood of things in terms of how well they seem to represent, or match, particular prototypes may lead one to ignore other relevant information,Heuristics,Availability Heuristic estimating the likelihood of events based on their availability in memory if instances come readily to mind (perhaps because of their vividness), we presume such events are common Example: airplane crash,Thinking,Overconfidence tendency to be more confident than correct tendency to overestimate the accuracy of ones beliefs and judgments,Thinking,Framing the way an issue is posed how an issue is framed can significantly affect decisions and judgments Example: What is the best way to market ground beef-as 25% fat or 75% lean?,Thinking,Belief Bias the tendency for ones preexisting beliefs to distort logical reasoning sometimes by making invalid conclusions seem valid or valid conclusions seem invalid Belief Perseverance clinging to ones initial conceptions after the basis on which they were formed has been discredited,Artificial Intelligence,Artificial Intelligence designing and programming computer systems to do intelligent things to simulate human thought processes intuitive reasoning learning understanding language,Artificial Intelligence,Computer Neural Networks computer circuits that mimic the brains interconnected neural cells performing tasks learning to recognize visual patterns learning to recognize smells,Language,Language our spoken, written, or gestured works and the way we combine them to communicate meaning Phoneme in a spoken language, the smallest distinctive sound unit,Language,Morpheme in a language, the smallest unit that carries meaning may be a word or a part of a word (such as a prefix) Grammar a system of rules in a language that enables us to communicate with and understand others,Language,Semantics the set of rules by which we derive meaning from morphemes, words, and sentences in a given language also, the study of meaning Syntax the rules for combining words into grammatically sensible sentences in a given language,Language,We are all born to recognize speech sounds from all the worlds languages,Language,Babbling Stage beginning at 3 to 4 months the stage of speech development in which the infant spontaneously utters various sounds at first unrelated to the household language One-Word Stage from about age 1 to 2 the stage in speech development during which a child speaks mostly in single words,Language,Two-Word Stage beginning about age 2 the stage in speech development during which a child speaks in mostly two-word statements Telegraphic Speech early speech stage in which the child speaks like a telegram-“go car”-using mostly nouns and verbs and omitting “auxiliary” words,Language,Language,Genes design the mechanisms for a language, and experience activates them as it modifies the brain,Language,New language learning gets harder with age,Language,Linguistic Determinism Whorf”s hypothesis that language determines the way we think,Language,The interplay of thought and language,Animal Thinking and Language,The straight-line part of the dance points in the direction of a nectar source, relative to the sun,Animal Thinking and Language,Gestured Communication,Animal Thinking and Language,Is this really language?,
