Are Within-subjects designs transparent?

摘要: Researchers frequently argue that within-subjects designs should be avoided because they result in research hypotheses are transparent to the subjects study. This conjecture was empirically tested by replicating several classic between-subjects experiments as designs. In two additional experiments, psychology students were given versions of these studies and asked guess what researcher hoping find (i.e. hypothesis), members Society for Judgment Decision Making (SJDM) predict how well would perform this task. On whole, unable identify hypothesis when provided with version experiments. Furthermore, SJDM largely inaccurate their predictions transparency a design.
