- - - - Common criticism for laboratory experiments
        
        can these findings be generalised to non-lab settings
    - - degree to which the results can be generalized to ppl in the target population
      - Target population = large population to which the results from the study are generalised to
      - Accessible population= population of participants that is available to the researcher
- - - - Mono-method bias = using only one method to operationalise the construct, influencing the results
      - Experiment effects = his/her attributes and expectancies may influence participants' responses
      - Mono-operation bias = using only operationalisation of a construct, under-representing the construct
      - Participant Reactivity = their motives and tendencies can affect their perception of the situations and their responses on the dv / influenced by demand characteristics
- - - - Temporal order = changes in the iv must precede the changes in the dv (happen before)
      - No other plausible explanation must exist for the effect
      - Relationship condition = the iv must be related to the effect (dv)
    - - Maturation= any physical or mental change that occurs with the passage of time, affecting dv scores
      - Instrumentation = changes in the way things are measured over the course of a study
      - History = any event that can produce the outcome, other than the treatment condition during the study before posttest measurement
      - Testing/ Test reactivity = score changes on the second test as they previously taken it the first time
      - Attrition/ Mortality = loss of participants because they don't show up/ drop out of the study
      - Regression artifact = effects that appear due to the treatment but are due to a regression to the mean
      - Selection = production of non-equivalent groups because a different selection procedure operates across groups
      - Additive/ Interactive effects = produced by the combined effect of two or more effects
        
        Selection-history = groups exposed to the same history event react differently bc they aint equated
        
        selection instrumentation
        
        selection testing
        
        selection regression artifact
