    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 speedier-but 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 one's 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 one's 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 one's preexisting beliefs to distort logical reasoning

    * sometimes by making invalid conclusions seem valid or valid conclusions seem invalid

    * Belief Perseverance

    * clinging to one's 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 brain's 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

    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?
