    tendency to seek out evidence that supports our hypothesis and neglect of distort evidence contradicting it
  11. Belief perserverance
    tendency to stick to our initial beliefs even when evidence contradicts them

    set of claims that seem scientific but are not

    testable beliefs not tested

    warning signs: exaggerated claims, lack of review, over reliance on anecdotes
  13. Apophenia

  20. Critical thinking
    a set of skills for evaluating all claims in an open minded fashion- allows us to overcome biases
  21. What are the 6 principles of critical thinking?
    • 1. ruling out rival hypotheses
    • 2. correlation vs causation- correlations doesn't equal causation
    • 3. falsifiability- can the claim be disproven
    • 4. replicability- idea that a studies finding can be duplicated

    Watson & Skinner focuses on uncovering the general laws of learning by looking outside the organisms

    "black box"- the mind is a black box, only need to look at what goes in and comes out

    help understand how we learn and importance on scientific rigor
  28. Cognitivism

    • hedge hogs- most confident
  45. Naturalistic observation

    • control group does not
  58. Manipulation of independent variable
    the dependent variable is what the experimenter measures to see if manipulation had an effect
  59. What are the pitfalls of experimental design?
    • placebo effect- improvement resulting from the mere expectation of improvement
