  • We humans are a funny species. As a civilization, we have invented the wheel, kept historical records to guide present and future generations, landed space ships on the moon, unlocked the atom, cracked the genetic code, and revolutionized the face of all we do with computers that bring us into the global Internet. When you stop to think about it, our list of triumphs is long and very impressive. Yet at the same time, we massacre each other in war, wreak havoc on the environment, discriminate against racial and ethnic groups different from our own, mistreat our partners in marriage, throw hard-earned money away in games of chance, take drugs that make us sick, and deceive ourselves into believing in alien abductions. What is it about the way we humans think that lead us to be both rational and irrational? How do we solve difficult problems and then evaluate the solutions, and what kinds of errors are we prone to make along the way? Are we logical in our reasoning, or are the judgments and decisions we make infected with bias? And what role does language have to play in the way we think? What is language and is it this capacity that most clearly separates humans from other animal species? In the coming days, we will examine some of the basic processes of thought and language, then address the question of how they are related. But first, let’s examine concepts – the basic building blocks of abstract thought and language.
  • Transcript of "Thinking, Language, & Intelligence"

    1. 1. Thinking, Language, & Intelligence “ The best way to have a good idea is to have lots of ideas.” Lines Pauling
    2. 2. Thinking <ul><li>What is it? </li></ul><ul><ul><li>Manipulation of words & images </li></ul></ul><ul><li>Cognitive psychology </li></ul><ul><ul><li>Studies how the mind </li></ul></ul><ul><ul><ul><li>Organizes perceptions </li></ul></ul></ul><ul><ul><ul><li>Processes information </li></ul></ul></ul><ul><ul><ul><li>Interprets experience </li></ul></ul></ul>
    3. 3. Concept Formation <ul><li>Concept </li></ul><ul><ul><li>A mental grouping of persons, places, ideas, events, or objects that share common properties </li></ul></ul><ul><ul><li>Priming </li></ul></ul><ul><ul><ul><li>When one concept is ‘activated’, others nearby in the network are primed </li></ul></ul></ul>
    4. 4. Concept Formation <ul><li>Prototype </li></ul><ul><ul><li>Best representative of a concept </li></ul></ul><ul><ul><li>Ex: Sport </li></ul></ul><ul><ul><ul><li>Football </li></ul></ul></ul><ul><ul><ul><li>Basketball </li></ul></ul></ul><ul><ul><ul><li>Golf </li></ul></ul></ul><ul><ul><ul><li>Chess </li></ul></ul></ul><ul><ul><ul><li>NASCAR </li></ul></ul></ul>
    5. 5. Problem Solving Strategies <ul><li>Trial & error </li></ul>
    6. 6. Problem Solving – Trial & Error <ul><li>Identify problem </li></ul><ul><ul><ul><li>Car won’t start </li></ul></ul></ul><ul><li>Gather information </li></ul><ul><ul><ul><li>Outta gas?

    7. 7. Problem Solving Strategies <ul><li>Trial & error </li></ul><ul><li>Algorithm </li></ul><ul><ul><li>A systematic, step-by-step problem-solving strategy, guaranteed to provide a solution </li></ul></ul><ul><li>Heuristic </li></ul><ul><ul><li>A rule of thumb that allows one to make judgments that are quick but often in error </li></ul></ul><ul><ul><li>L K C C O </li></ul></ul><ul><li>Insight </li></ul>
    8. 8. Water Problem

    10. 10. Problems with Problem Solving <ul><li>Confirmation Bias </li></ul><ul><ul><li>The inclination to search only for evidence that will verify one’s beliefs </li></ul></ul><ul><li>Belief Perseverance </li></ul><ul><ul><li>The tendency to cling to beliefs even after they have been discredited </li></ul></ul><ul><ul><li>Anderson (1980) </li></ul></ul>
    11. 11. Decision Making <ul><li>Try to make best choice from alternatives </li></ul><ul><ul><li>Utility: value of given outcome </li></ul></ul><ul><ul><li>Probability: likelihood you’ll achieve it </li></ul></ul><ul><li>Representativeness Heuristic </li></ul><ul><ul><li>A tendency to estimate the likelihood of an event in terms of how typical (how similar to the prototype) it seems </li></ul></ul><ul><li>Availability Heuristic </li></ul><ul><ul><li>A tendency to estimate the </li></ul></ul><ul><ul><li>likelihood of an event in terms of </li></ul></ul><ul><ul><li>how easily instances of it can be </li></ul></ul><ul><ul><li>recalled </li></ul></ul>
    12. 12. Language <ul><li>Formal system of communication </li></ul><ul><ul><li>Spoken,written, and/or gestures </li></ul></ul><ul><li>Between 5,000 and 6,000 languages, worldwide </li></ul><ul><ul><li>Most languages also have many dialects </li></ul></ul>

    16. 16. Language Acquisition <ul><li>No one disputes the stages of language development </li></ul><ul><li>But there are two main questions in terms of what it all means </li></ul><ul><ul><li>Is language acquisition a product of nature or nurture? </li></ul></ul><ul><ul><li>Which comes first – language or thought? </li></ul></ul>
