(PDF) What did the OSC replication initiative reveal about ... The need for a direct replication is even more pressing since—to the best of our knowledge—the only published conceptual replications offer … Chapter 14 Flashcards | Quizlet Psychological replication Replications in Psychology Research: How Often Do They ... We hypothesized that at the direct and conceptual This involves repeating the procedure of a previous experiment. Zwaan et al. •When results fail to replicate in conceptual replication studies, the researcher concludes the presence of effect variation. This discussion of direct vs. conceptual replication is a little bit facile, in my opinion. This is the use of different methods to retest the hypothesis or result of a previous experiment. The ability of the conceptual replication to do this is based on the fact that psychological variables are constructs that can’t be measured directly, by definition. At least two key types of replication exist: direct and conceptual. Conceptual replication generally refers to cases where researchers ‘tweak’ the methods of previous studies [ 43] and when successful, may be informative with regard to the boundaries and possible moderators of an effect. 1. Psychology has promoted “exact” or “direct” replications, reflecting an interest in statistical conclusion validity of the original findings. Exact replications tell us whether the original findings are true, at least under the exact conditions tested. Conceptual replications help confirm whether the theoretical idea behind the findings is true, and under what conditions these findings will occur. •The Causal Replication Framework provides assumptions for determining “high quality” direct and conceptual replication designs for the … Conceptual replication helps us mitigate that risk, as I cover in this post on the history of cognitive dissonance. Current debates about the replication crisis in psychology take it for granted that direct replication is valuable, largely focusing on its role in uncovering questionable statistical practices. Thus, the replicability crisis requires us to evaluate VET from a practical perspective and determine when conceptual replications confirm or mislead. Case Study 1: Wearing red makes you look hotter. In a direct replication, the new research team essentially seeks to duplicate the sampling and experimental procedures of the original research by following the same “experimental recipe” provided in the methods sec-tion of the original publication. Duplication vs Replication . Of course, that is not so; it is customary to distinguish among several types of replication attempts: direct replication, systematic replication, and … terms “direct” versus “conceptual” replications, researchers should conceptualize replications with respect to their relative method-ological similarity to a previous study. Anderson and Maxwell (2016) Presented in Figure 1 is a replication taxonomy that aims to achieve just this, informed by earlier taxonomies proposed by Hendrick (1991) and Schmidt (2009). Sidman A direct replication occurs when a new set of authors attempt to replicate the original experimental procedure to an exact degree as possible. Stroebe and Strack reject direct replication in favor of conceptual replication, arguing that “the true purpose of replications is a (repeated) test of a theoreti-cal hypothesis rather than an assessment of the reliability of a particular experimental procedure” (p. 61) In this commentary, I challenge these claims and their This is the use of different methods to retest the hypothesis or result of a previous experiment. Strube (1989). See "About Data Replication and Integration" and "About Data Replication and Integration Features" for information about the types of environments. These results highlight the need for robust replication of positive tDCS results to better understand the efficacy of, and mechanisms involved in, non-invasive brain stimulation. The Replication … At the same time, it is clear that direct replications are based on an attempt to be as exact as possible, whereas conceptual replications are not. On the other hand, conceptual replication is the use of different authors, different methods, and different measures to repeat the test of a hypothesis or experimental result. Direct replication means that you reproduce, as faithfully as possible, the procedures and conditions of the original study. Here's a useful discussion paper that is critical of the feasibility of direct replication (see attachment): Stroebe, W., & Strack, F. (2014). It is tied to the concept of the gene and its generalization in an evolutionary context [see the entry evolution].Richard Dawkins introduced the notion of replicators—things that self-replicate—as a universalization of evolutionary understandings of genes. This article takes a broader look at the notion of replication in psychological experiments. Direct replication (and can you ever do exactly the same study?) conceptual replications (n = 4,559) and one highly powered, preregis-tered, direct replication ( n = 1,235) conducted with the authors of the original paper, weobservednoeffect ofsigning first onhonest report-ing. In a systematic review of the literature, encompassing multiple academic disciplines, Gómez et al. Term. (2016). Variables in a psychological study usually represent theoretical constructs, and the aim of replication usually is to get as close to representing the same original construct as possible. This means that a direct replication is far from a trivial undertaking. A replication study can be conceptual or direct (Nosek et al., 2015). Here, three labs attempted direct and conceptual replications of Morriss, Macdonald, et al. They argue that exact replications are superior and therefore original authors should provide a “replication … So the focus should rightly be on the result. This article discusses different types of replications (e.g., direct vs. conceptual) and how they can benefit the field of IS. Replication Experiment 1 (n = 74 recruited at the University of Saskatchewan) used the same non-zero addition and subtraction problems and trial event sequence as Mathieu et al., but participants completed blocks of pure addition and pure subtraction followed by the mixed-operation condition used by Mathieu et al. A direct replication aims to mimic the original study as closely as possible (Simons, 2014). In a nutshell, direct replications essentially try to redo “the same” experiment (or at least something very close), whereas the conceptual replications try to operationalize the same question or concept/effect in a different way. It means that exactly same equipment, material, stimuli, design and statistical analysis should be used. Only direct replications can do that. Specifically, as a field, we need to draw a sharper distinction between (a) replications (exact vs. conceptual) and (b) the integrity of the research process (see Figure) when considering the credibility of knowledge generated in psychological science. Direct replication is repeating an experimental manipulation between or within participants " Intra-participant replication is repeating the experimental effect with the same participant in the same study (i.e., within participant). A within-groups design (vs. between-groups in the previous study) identified no overall effects of tDCS on spatial bias, and no current × performance interaction. No new variables are included in the replication. But if you are interested in theoretical progress via experimentation, targeted conceptual replication is also required. We acknowledge that there is debate within the field about the relative merits of conceptual versus direct replications. In a direct replication, a different set of researchers duplicates the sampling and methodology of the original research. This involves repeating the procedure of a previous experiment. There is no clear dividing line between direct and conceptual replications but what I am advocating are not conceptual replications. Given the policy applications of this result, it is important to up-date the scientific record regardi ng the veracity of these results. Direct Replication refers to replication of an experimental manipulation either within or between participants. (2010) identified 18 different types of replication. Conceptual replication. The replication crisis The importance of replication Replication not done nearly as often as it should due to the incentives researchers face-Priority placed on novel findings but what good are they if they are replicable -Direct and conceptual replications Pros Cons (when attempting to publish) Direct replication Informative about whether OG findings may have been false pos. - Replication of research using different procedures for manipulating and measuring the variables that were used in the original study. Conceptual replication and extension was attempted at McGill University (conceptual replica-tion 1) and Texas A&M University (conceptual replication 2) using uneasiness ratings and SCR but also ERPs; para-digm parameters were modified to facilitate the elicitation of ERPs. Results showed that the direct replication failed, despite being conducted at the same lab site as the original study; moreover, in contrast to Morriss, Macdonald, et al. Here's a useful discussion paper that is critical of the feasibility of direct replication (see attachment): Stroebe, W., & Strack, F. (2014). The... The article then presents a specific example of an implementation strategy called Getting To Outcomes© to describe how to … In response to my response to his post , +Rolf Zwaan wrote another interesting post on the limits and value of direct replication. How attractive/pretty do you think this person is? Such conceptual replications, more so than direct replications, may yield greater insight into the legitimacy of the theoretical ideas being tested (see Crandall & Sherman, 2016). So while the shape might be a factor (possibly, not certainly), the primary and "direct" reason is the difference in size, not the shape.
