Question Answer
Replication repeating research to determine the extent to which findings generalize across time/situations
Why must scientific findings be replicable? to avoid false positives and to allow findings to become a part of trusted scientific knowledge
false positives test results which wrongly indicate that a finding is true
replication crisis the problem in many sciences (esp. psych) in which many credited studies are found to not be replicable, suggesting original research was sloppy/faked
types of replication - exact replication - conceptual replication
exact replication attempt to exactly recreate scientific methods used in earlier studies
conceptual replication attempt to confirm previous studies using different methods that test the same idea i.e. same hypothesis, different methods/measures.
why is conceptual replication useful? because it tests if findings are replicable AS WELL AS in which conditions they occur
examples of non-replication in psych - "metaphorical priming" - power posing - marshmallow test - plate size and portion control - Zimbardo and Milgram
Why does non-replication occur in psych? - the scientists attempting replication may not be skilled enough to carry it out - results may be faked - small sample size - statistically insignificant results due to chance - findings may only be true for some people in some circumstances (not universal) - quality of replication: may have made error
solutions to replication crisis - create outlets where replication attempts are recorded - encourage scientists to replicate earlier work (this is often discourage because it doesn't represent original thinking"
