Investigating variation in replicability

Although replication is a central tenet of science, direct replications are rare in psychology. This research tested variation in the replicability of 13 classic and contemporary effects across 36 independent samples totaling 6,344 participants. In the aggregate, 10 effects replicated consistently. One effect – imagined contact reducing prejudice – showed weak support for replicability. And two effects – flag priming influencing conservatism and currency priming influencing system justification – did not replicate. We compared whether the conditions such as lab versus online or US versus international sample predicted effect magnitudes. By and large they did not. The results of this small sample of effects suggest that replicability is more dependent on the effect itself than on the sample and setting used to investigate the effect

Finding Mr. Wrong: Divergences in Mate Preferences and Mate Selection

89 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2007.When asked to choose among secure or insecure partner prototypes, research has shown that people tend to select secure individuals as their first choice. Despite this pattern, in reality not everyone selects secure partners. The goal of the current study was to examine some of the underlying processes of insecure partner selection. Experiment 1 used a cognitive load manipulation to determine if limited mental resources lead people to find insecure partners more attractive. Experiment 2 examined the role of flattery in the selection of insecure partners. Experiment 3 focused on the self-presentation strategies of insecure individuals that may make them attractive to potential mates. I found that flattery, but not cognitive distraction, increased attraction to insecure partners. Experiment 3 demonstrated that insecure individuals presented themselves as kind, humorous, and interesting people to potential mates. Anxious people also seemed as secure as genuinely secure people. These results suggest that positive feedback from insecure people makes them more attractive as partners and also that insecure individuals have numerous dating tactics that they may use to win over dating partners.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD

Data from investigating variation in replicability: A "Many Labs" replication project

This dataset is from the Many Labs Replication Project in which 13 effects were replicated across 36 samples and over 6,000 participants. Data from the replications are included, along with demographic variables about the participants and contextual information about the environment in which the replication was conducted. Data were collected in-lab and online through a standardized procedure administered via an online link. The dataset is stored on the Open Science Framework website. These data could be used to further investigate the results of the included 13 effects or to study replication and generalizability more broadly. Keywords: replication, generalizability, contex

Theory building through replication response to commentaries on the "Many labs" replication project

Responds to the comments made by Monin and Oppenheimer (see record 2014-37961-001), Ferguson et al. (see record 2014-38072-001), Crisp et al. (see record 2014-38072-002), and Schwarz & Strack (see record 2014-38072-003) on the current authors original article (see record 2014-20922-002). The current authors thank the commentators for their productive discussion of the Many Labs project. They entirely agree with the main theme across the commentaries: direct replication does not guarantee that the same effect was tested. As noted by Nosek and Lakens (2014, p. 137), ‘‘direct replication is the attempt to duplicate the conditions and procedure that existing theory and evidence anticipate as necessary for obtaining the effect.’’ Attempting to do so does not guarantee success, but it does provide substantial opportunity for theoretical development building on empirical evidence
