Document Summary
Elliot et al (2007) - did multiple experiments (6); replicated his own effects. Replication issue - experiment must be replicated exactly. If you"re adding something new, include original methods etc. File-drawer problem - falling to replicate something and then putting away the experiment. Milgram experiment: psychological realism - participant became distressed as if the experiment were real - if experiment makes a person feel this kind of effect, then the experiment has ecological validity. Mundane realism: describes the degree to which the materials and procedures involved in an experiment are similar to events that occur in the real world. Converging evidence - gather converging evidence from multiple perspectives and methods. Trade-offs can"t have 100% of every type of validity. Financial and/or time considerations can cause researchers to sacrifice construct validity. The methods themselves involve trade-offs between internal and external a validity. Did not really give participants a choice to leave. Influenced participants, got them to lie to visitors, unjustifiable deception.
