Correcting the Past: Failures to Replicate Psi

Across 7 experiments (N 3,289), we replicate the procedure of Experiments 8 and 9 from Bem (2011), which had originally demonstrated retroactive facilitation of recall. We failed to replicate that finding. We further conduct a meta-analysis of all replication attempts of these experiments and find that the average effect size (d 0.04) is no different from 0. We discuss some reasons for differen...

Journal of Personality and Social Psychology Correcting the Past: Failures to Replicate Psi

Failures to replicate hyper-retrieval-induced forgetting in arithmetic memory.

Campbell and Phenix (2009) observed retrieval-induced forgetting (slower response time) for simple addition facts (e.g., 3 + 4) immediately following 40 retrieval-practice blocks of their multiplication counterparts (3 × 4 = ?). A subsequent single retrieval of the previously unpracticed multiplication problems, however, produced an retrieval-induced forgetting (RIF) effect about twice as large...

Two Failures to Replicate High-Performance-Goal Priming Effects

Bargh et al. (2001) reported two experiments in which people were exposed to words related to achievement (e.g., strive, attain) or to neutral words, and then performed a demanding cognitive task. Performance on the task was enhanced after exposure to the achievement related words. Bargh and colleagues concluded that better performance was due to the achievement words having activated a "high-p...

Non-replication in Association Studies: ‘pseudo-failures’ to Replicate?

Recently, serious doubts have been cast on the usefulness of association studies as a means to genetically 'dissect' complex diseases, because most initial findings fail to replicate in subsequent studies. The reasons usually invoked are population stratification, genetic heterogeneity and inflated Type I errors. In this article, we argue that, even when these problems are addressed, the scient...
