Jeff Stone (University of Arizona) : Adventures in replicating and extending classic dissonance effects in the lab and in the wild

The methodological evolution in social psychology has raised questions about the reliability of classic findings given that many were produced (and reproduced) on small samples in a lab setting. To increase the power and reliability of new findings, many researchers are turning to online subject pool sites like MTurk, in part because they permit faster collection of data from large samples. Are the lab and MTurk contexts equally suited for capturing dissonance processes? I will present research in which my students and I replicated one classic dissonance effect, the post-decision spreading of alternatives (Brehm, 1956), in the lab with a moderately large sample of college students. I will also present 5 studies in which we failed to reliably replicate another classic dissonance process, the reverse-incentive effect (Festinger & Carlsmith, 1959), with very large MTurk samples. The discussion will include considerations for replicating and testing novel predictions about dissonance in the lab and in the wild.
