  17. What is the ATMOSPHERE THEORY?
    • a processing theory which explains errors in judging the validity of categorical syllogisms in terms of misleading expectations surrounding certain characteristics of the premises (for example, the fact that both premises are universal will lead to acceptance of universal conclusions which do not follow
    • validly)

  22. What is CONVERSION THEORY?

  27. What is an HEIRARCHIAL STRUCTURE?
    a characteristic of problem structure which supports the breaking down of a problem into an organized series of simpler sub-tasks, and those simpler tasks into a set of still simpler tasks, with this process continuing unitl the tasks are so simple as to be executed by some elementary information process

  31. What is a MEANS-ENDS ANALYSIS?
    a heuristic search technique that avoids the difficulty of local highs by postulating a series of sub-goals that systematically identify and reduce the distance between a given state and the goal state.
  32. What is the MENTAL MODELS THEORY?

  38. What is SCHEMA INDUCTION?
    the recognition of the essential characteristics that define a situation; this recognition results from observing several specific situations of that type´╗┐
  39. What is SEARCH SPACE?
    the set of all possible states that can be reached from a problem's starting state by following the problem's transition rule(s); (synonymous with problem space)

  41. What is a STATE TRANSITION PROBLEM?
    In state transition terms, a problem is defined by means of three components: 1) a starting state, 2) a goal state, and 3) a set of transition rules that govern moves from one state to another
