    Word frequency effect
  29. Our ability to acess words in a sentence is affected by sematics. Attempt to figure out what a sentence means as we read it.
    Context effects
  30. Words have more than one meaning. Context clears up ambiguity after all meanings of a word have been breifly accessed.

  43. An incorrect word is substituted for the correct word. Often related to top down processing. Terrain-Train
    Word subsitutions
  44. Conversations go more smoothly if participants have shared knowledge.
    Semantic coordination
  45. Speaker constructs sentences so they include
    -given information

  49. Stimuli in same categories are more difficult to discriminate from one another than stimuli in two different categories.
    Categorical perception
  50. Cognitive process by which people start w/info and come to conclusions that go beyond that information.
  51. Reasoning that involves syllogisms in which a conclusion logically follows from premises.
    Deductive reasoning
  52. -two statements called premises
    -third statements called conclusion
    -The conclusion follows from the premises based on the rules of logic.
    -Categorical syllogism
    Describe relation between two categories using all, no, or some. Ex all birds are animals.
  53. -Premise 1: All A are B
    -Premise 2: All B are C
    -Conclusion: Therefore, all A are C
    Aristotle’s “perfect” syllogism
  54. Ask people if conclusion follows logically from premises
  55. Ask people to indicate what logically follows from premises
  56. Use of words all, some, or no (none) creates an over all mood that can influence the evaluation of the conclusion.
    Atmosphere affect
  57. If syllogism is true or agrees with a person
    beliefs, more likely to be judged valid
    Belief bias
  58. A specific situation that is represented in a person’s mind that can be used to help determine the validity of syllogisms. Create, test,
    and revise.
    Mental models
  59. -Two premises and a conclusion
    -first premise has the form “if p, then g”
    - second premise is a statement about “p” or “g”
    -antecedent “if” term
    -consequent “then” term
    Conditional syllogisms
  60. Effect of using real world items in a conditional reasoning problem. Task to determine minimum # of cards to turn over to test a given rule. Ex: E K 4 7 Rule: If there is a vowel on one side, then there is an even number on the other side. Test: which cards need to be turned over to test the rule? Only need to turn over E and 7.
    The Wason four card problem
  61. To test a rule, you must look for situations that falsify the rule. Most participants fail to do this. When problem is stated in concrete everyday terms, correct responses greatly increase.
    Falsification principle
  62. If A is satisfied, B can be carried out. People are familiar w/rules Ex. If you are at least 21, you can drink alcohol at the bar.

  65. In this type of task, participants decide whether a string of letters is a word or not.
    Lexical Decision Task
  66. This approach to parsing takes into account both semantic and syntactic information to determine parsing as a person reads a sentence.
    Interactionist Approach to Parsing
  67. This is the type of structure of language, with small components (ex: phoneme) making up larger components (ex: word) that can make up an even larger component (ex: sentence).
    Hierarchical Structure
  68. This type of inference connects an object or person in one sentence to an object or person in another sentence (such as a pronoun).
    Anaphoric Inference
  69. This type of reasoning results in conclusions that are not 100% true and is based on evidence
    Inductive reasioning
  70. The type of valid syllogism is represented in the form “If p then q. Not q. Therefore not p.”
    is called (Hint: affirming/denying the…)
    Denying the Consequent
  71. The law of large numbers states that a larger __________leads to a more representative group of a population

  73. This type of inference involves an inference about tools or methods.
    Instrumental Inference
  74. This characteristic of the physical energy produced by conversational speech is also responsible for making new languages difficult to parse
  75. The First Cognitive Psychologists

    Mental chronometry
    Measures how long cognitive process takes

    Reaction–time (RT) experiment
    Measures interval between stimulus presentation and person’s response to stimulus
  76. Flow diagram representing what happens
    as a person directs attention to one stimulus

    Second is a flow diagram for
    broadbent’s filter model of attention.
    Information that goes through the
    filter gets picked up by the detector and stored in memory
  77. Atkinson and Shiffrin (1968)
    o Describes memory as a mechanism that
    processes information through a series of stages
    o Sensory memory: lots of information;
    fades rapidly
    o Short term: 15-20 seconds unless
    o Long term: long periods of time
    Modal Model of Memory
  78. o When the type of task that occurs
    during encoding matches the type of task that occurs during retrieval
    Ex: Rhyming-rhyming instead of rhyming-meaning
    o Can result in enhanced memory
