  1. Experimenter Effect
    Participants might change their actions if they know they are being watched.
  2. Observer Bias
    If observers know which is control vs. experimental group - They may skew data.
  3. Researcher Attribute Effect
    Unchangeable (like gender)
  4. Hawthorne Effect
    Observing people infuences their actions. Make observations less "in your face"
  5. Testing Effect
    Participants primes for what is being tested.
  6. Maturation Effect
    People change over time, these effect the result of the study.
  7. Experimental Mortality Effect
    Participants drop out of before the study is complete.
  8. Selection Bias Effect
    When groups are not the same at the beginning.
  9. Intersubject Bias
    When participants are influenced by one another.
  10. Componsaory Rivalry
    Compensating for the missing stimulus by working harder
  11. Demoralization
    Feelings of depravation in control group may result in their giving up.
  12. History
    Anything that is going on outside of your study that may effect the outcomes.
  13. Instrumentation
