replication study example

For example, the famous experiment by Otto Loewi (1936 Nobel Prize in Physiology or Medicine) showed that the inhibitory factor “vagusstoff,” subsequently determined to be acetylcholine, was released from the vagus nerve of frogs, suggesting that neurotransmission was a chemical process. Papers I haven’t read might have much less power. Recall that “to be a replication, 2 things must be true: outcomes consistent with a prior claim would increase confidence in the claim, and outcomes inconsistent with a prior claim would decrease confidence in the claim." ( Log Out /  Conceptual Replication and Random Factors. More on this on my blog: http://politicalsciencereplication.wordpress.com/, There’s also a great article about replicating in Science: http://sciencecareers.sciencemag.org/career_magazine/previous_issues/articles/2011_12_02/caredit.a1100133. View Large Download. (2011; total N = 75). No, Is the Subject Area "Social sciences" applicable to this article? According to a 2018 survey of 200 meta-analyses, "psychological research is, on average, afflicted with low statistical power". Designing a replication with a different methodology requires understanding of the theory and methods so that any outcome is considered diagnostic evidence about the prior claim. The replication crisis in psychology refers to concerns about the credibility of findings in psychological science. I’m also starting a replication workshop with my stats beginner students – I’ll let them know about your success, this will be highly motivating! Cuddy and her colleagues responded with an overview of 33 published studies that have shown psychological and physiological effects of … Example 3 may also be seen as applying the two treatments to two different populations (students in one school and students in the other school) Observational studies are particularly prone to pseudoreplication. This is illustrated by shrinking generalizability and replicability space because the theory must be constrained to ever narrowing conditions [12]. In practice, this means that replication is often limited to relatively close adherence to original methods for topics in which theory and methodology is immature—a circumstance commonly called “direct” or “close” replication—because the similarity of methods serves as a stand-in for theoretical and measurement precision. Matthews (2012) reports 11 replication attempts (total N = 2180) of one study that tests a decision-by-sampling prediction reported in Ungemach et al. Simultaneously, failures-to-replicate have spurred debate about the meaning of replication and its implications for research credibility. This text takes the reader from seeking out a suitable study for replication, through deciding on the most valuable form of replication approach, to its execution, discussion, and writing up for publication. Replication is important because it adds information about the reliability of the conclusions or estimates to be drawn from the data. By doing so, that prior research is confirmed as being both accurate and broadly applicable, since the replication study typically changes one or more variables of the original … Looking for policy-relevant behavioral science on insurance, investment, saving, pensions, etc Any suggestions for blogs/papers/other lists? Yes These factors can and should be eliminated as much as possible. Replication is characterized as the boring, rote, clean-up work of science. This may be caused by the use of a single grade per image, or different data. Only counting replications that mimic the experimental procedure of Tykocinski (2008), the replication-to-initial sample size ratio is 11.28 : 1. The dialogue between theory and evidence facilitates identification of contours, constraints, and expectations about the phenomena under study. Replication studies help in confirming that the findings of the original study are accurate and applicable under different situations. I’m about to set up a replication workshop and I could need some advice/ exchange how to do this efficiently. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. The following quote is from Montgomery's Experimental Design: There is an important distinction between replication and repeated measurements.. For example, suppose that a silicon wafer is etched in a single-wafer plasma etching process, and a critical dimension on this wafer is measured three times. When theories are too immature to make clear predictions, repetition of original procedures becomes very useful. Teen Pregnancy Prevention (TPP) Replication Study Abt Associates Inc. Impact Study Design Report pg. Ideally this is done using code provided by the study authors. No, Is the Subject Area "Elections" applicable to this article? Found inside – Page 174A prime example of this is the use of research findings and evidence by the ... is to facilitate and promote the critique and replication of studies. Similarly, two different researchers studying the same dinosaur bone in the same way should come to the same conclusions regarding its … Single studies, whether they pursue novel ends or confront existing expectations, never definitively confirm or disconfirm theories. A replication study that validates existing research could, for example, improve the rating of a new law enforcement method from “promising” to “effective.” The quest for reliability cannot mask the uncertainty inherent in all science. ii . The answer shifts the conception of replication from a boring, uncreative, housekeeping activity to an exciting, generative, vital contributor to research progress. The statistical methods that assess that reliability rely on replication. To inspire new research combing previous findings from related studies. These are generalizability tests.

Fig 1‘s left panel illustrates a discovery and conditions around it to which it is potentially generalizable. Found insideFostering Integrity in Research identifies best practices in research and recommends practical options for discouraging and addressing research misconduct and detrimental research practices. Replication challenges have spawned initiatives to improve research rigor and transparency such as preregistration and open data, materials, and code [4–6]. e3000691. Replication studies determine both the validity of scientific conclusions and provide insights into the type of methods and reporting that are necessary for … Zwaan et al replicate 3 findings, and do so twice for each. How do we decide whether something is a replication? University of Virginia, Charlottesville, Virginia, United States of America, Affiliation did, we failed to confirm an effect of power posing,” the replication team said. For example, psychological research, where the notion of a replication crisis first emerged, had an estimated overall replication study rate of 1.07% before serious attention was paid to improving the state of research replication in that discipline. So, if you know about other published replication attempts (so not in the OSF or psycfiledrawer), please let me know! Although one of these studies explicitly refer-enced nonreplication as the goal, others were vaguer in their intentions. In these examples, a set of studies was selected and a single replication attempt was made to confirm results of each previous study, or one-to-one comparisons were made. This case study focuses on the New York City Charter High School for Architecture, Engineering, and Construction Industries (AECI), a charter operator. In taking an interdisciplinary approach, these two volumes target a broad audience and fill a gap in the existing reference literature for a general guide to the core concepts that inform qualitative research practices. Failures-to-replicate or generalize shrink the space (dotted circle shows original plausible space). replication of specific important psychological studies by multiple investigators. Wood, which I recently presented at the “Reproducibility and Integrity in Scientific Research” workshop at the University of Canterbury. This is me, because our replication paper is the first paper I ever published, yeah! This study shows the challenges of reproducing deep learning method results, and the need for more replication and reproduction studies to validate deep learning methods, especially for medical image analysis. Explain the four different types of replications and the purpose of each. Zwaan et al replicate 3 findings, and do so twice for each. That is not a problem, that is progress. In our view, this is a promising detail: in order to foster replicability, one avenue may be to make replication studies a mandatory part of curricula as well as of doctoral theses. According to common understanding, replication is repeating a study’s procedure and observing whether the prior finding recurs. Replication studies Replication Policy. Unfortunately, not much” | Job van Wolferen, Replication in Psychological Science | Job van Wolferen, “What can we learn from van Wolferen et al.’s replication attempt? A lack of scientific transparency, however, should not be allowed to contribute to that uncertainty. replication studies examples. Only counting the replications in which we try to stay as close to the original materials as possible, we have three (2-condition) studies with a total N of 451, versus 40 in the original study. When there is uncertainty about the status of claims and the quality of methods, there is no easy solution to distinguishing between motivated and principled reasoning about evidence. To achieve 95% probability of replicating a significant p value with an exact replication, the initial p value would have had to be p = 0.00032 [ … Repeatedly testing replicability and generalizability across units, treatments, outcomes, and settings facilitates improvement in theoretical specificity and future prediction. Replication is a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances. The sample sizes and ratios are 336/40 = 8.40:1, 352/42 = 8.38:1, and 304/42+60 = 2.98:1. Found insideReproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Time-of-day for data collection may be expected to be irrelevant for a claim about personality and parenting or critical for a claim about circadian rhythms and inhibition. For example, phenotype data is not completely the same across the GWASs: SPNBMD was a combination of L2–L4 in FHS100K and Icelandic deCODE but a combination of L1–L4 in UK-NL and the present replication study. This is distinct from retesting a claim using the same analyses and same data (usually referred to as reproducibility or computational reproducibility) and using the same data with different analyses (usually referred to as robustness). http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0051382, Thank you! Create a free website or blog at WordPress.com. Ironically, the value of replication may be strongest when existing understanding is weakest. To achieve that, researchers should be rewarded for articulating their theories clearly and a priori so that they can be productively confronted with evidence [4,6]. But if you continued driving and saw a second, and then a third, you might become more confident in your observations. Nicole, Pingback: Best of replication & data sharing Collection 1 | Political Science Replication, Pingback: “What can we learn from van Wolferen et al.’s replication attempt? Replications often repeat procedures because theories are too vague and methods too poorly understood to productively conduct replications and advance theoretical understanding otherwise [8]. Covering a wide range of topics, from probability and sampling distribution to statistical theorems and chi-square, this introductory book helps readers learn not only how to use formulae to calculate statistics, but also how specific ... link.

The replication studies in our sample may differ in terms of (a) their results, i.e., they may negate or (partially) reinforce the results of the replicated article, and (b) the extent of replication (narrow or scientific). A complete theoretical account eliminates generalizability space because the theoretical expectations are so clear and precise that all tests are replication tests.

It turns out that we were unable to replicate the protection effect in the Netherlands (and the U.S.)*. %PDF-1.7 %���� The Teen Pregnancy Prevention (TPP) Replication Study is evaluating three replications of three evidence-based program models, for a total of nine sites funded through the Office of Adolescent Health (OAH) Teen Pregnancy Prevention (TPP) program. Galak et al (2012) report 7 replication attempts (total N = 3,289) of two studies on precognition reported in Bem (2011; total N = 150). Magical thinking in predictions of negative events : Evidence for tempting fate but not for a protection effect. If minor changes are allowed, then what counts as minor to still qualify as repeating the procedure? Successful replication provides evidence of generalizability across the conditions that inevitably differ from the original study; Unsuccessful replication indicates that the reliability of the finding may be more constrained than recognized previously. Great, looking forward! According to a view assumed by many scientists and philosophers of science and standardly found in science textbooks, it is controlled ex perience which provides the basis for distinguishing between acceptable and unacceptable theories in ... Replication is a study for which any outcome would be considered diagnostic evidence about a claim from prior research. How to use replication in a sentence. That’s great. What if authors of new papers would be required to report properly powered replications of their new ‘initial’ studies? Copycats in science: The role of replication: Scientists aim for their studies' findings to be replicable — so that, for example, an experiment testing ideas about the attraction between electrons and protons should yield the same results when repeated in different labs. We cannot reproduce an earthquake, era, or election, but replication is not about repeating historical events. Let’s see if we can replicate these initiatives in polsci… If you know of people who incorporate replication in stats training, please let me know. Procedural definitions of replication are masks for underdeveloped theoretical expectations, and “conceptual replications” as they are identified in practice often fail to meet the criteria we develop here and deem essential for a test to qualify as a replication. The structure of common mental disorders: a replication study in a community sample of adolescents and young adults Int J Methods Psychiatr Res . I probably only know about these papers because I am an author on one of them, and because the other two have unusually large numbers of highly powered studies. DEFINITIONS In discussing these terms, it is important to distinguish between research projects and research programs. The original study by Bargh et al where an elderly-prime led participants to walk more slowly had 30 participants in both Study 2a and 2b, and a replication by Doyen et al had 120, ratio is only 2:1. The initial study had 40 participants. We ran studies that built on this idea but consistently did not find the results we predicted. Change ). The ambiguity between disconfirming an original claim or identifying a boundary condition also means that understanding whether or not a study is a replication can change due to accumulation of knowledge. More broadly, it is not possible to recreate an earthquake, a supernova, the Pleistocene, or an election. Found inside – Page 1Primarily addressed to qualitative social scientists, this volume is also appropriate for anyone who wants to study attitudes and beliefs. ( A ) Total RNA levels in P493-6 cells 0 hr compared to 24 hr after release from tetracycline (meta-analysis p = 0.0488). The Stanford Prison Experiment was pre-tested. Accumulating failures-to-replicate could result in a much narrower but more precise set of circumstances in which evidence for the claim is replicable, or it may result in failure to ever establish conditions for replicability and relegate the claim to irrelevance. The fundamental question is: of the innumerable variations in units, treatments, outcomes, and settings, which ones matter? 3752 0 obj <> endobj Replication is a central part of the iterative maturing cycle of description, prediction, and explanation.

Second, it's an example of how different media outlets assign catchy--but sometimes erroneous--headlines on the same study. ( Log Out /  The replication recipe provides a structured set of questions to guide the process of creating a method section for a replication study. Prior commentators have drawn distinctions between types of replication such as “direct” versus “conceptual” replication and argue in favor of valuing one over the other (e.g., [9, 10]). Replicable evidence provides anchors for that iterative process. I’ll read your paper and add it to the post (along with the above). Yes Enter your email address to follow this blog and receive notifications of new posts by email! Regression can sometimes account for lack of replication, provided data are close enough to each other. Replication in an independent sample is therefore key, but replication is more elusive and difficult with clinic-based studies, as we discuss later. Found inside – Page 34Treatment Effects The Texas Effect Original Replication Diff. ... contribution relative to the endowment in each study for consistency. of types of studies. However, as a theoretical commitment, replication does imply precommitment to taking all outcomes seriously. The sample sizes and ratios are 336/40 = 8.40:1, 352/42 = 8.38:1, and 304/42+60 = 2.98:1. The replication is so important in science. The replication reduces variability in experimental results. Stop of variability increases their significance and the confidence level. Finally, the researcher can draw conclusions about an experimental. Unfortunately, not much”. Found inside – Page 190The examples discussed above illustrate that the molecular mechanisms used by RNA viruses to ensure the incorporation of the correct genomic material are ... It works by "unzipping" the double-stranded DNA so that replication can subsequently occur. The original study was performed with so-called winter frogs. Individual studies do not provide comprehensive or definitive evidence about all conditions for observing evidence about claims. Better theories are those that make it clear how they can be supported and challenged by replication. Because replication is defined based on theoretical expectations, not everyone will agree that one study is a replication of another. We have a paper out on replication attempts. This definition reduces emphasis on operational characteristics of the study and increases emphasis on the interpretation of possible outcomes. Youth perceptions of three interparental conflict variables are stud-ied: frequency of disagreement, parents' use of an overt conflict style, and parents' use of a covert conflict style. This differs from the file drawer bias since it is contingent on the outcomes of both the original study and the replication; it differs from the repeat study bias which is agnostic to the outcome of the replication study. This definition is intuitive, easy to apply, and incorrect. No, Is the Subject Area "Open data" applicable to this article? Yes For more information about PLOS Subject Areas, click This definition reduces emphasis on operational characteristics of the study and increases emphasis on the interpretation of possible outcomes. The post is based on my paper with Benjamin D.K. First, there is a type called “exact replication” (also called "direct replication"). The chronicle article talks about a Dijksterhuis replication paper but that’s still in press: 3771 0 obj <>/Filter/FlateDecode/ID[<9E6201A1E541154DBD84EE95A0760F1B>]/Index[3752 32]/Info 3751 0 R/Length 100/Prev 829006/Root 3753 0 R/Size 3784/Type/XRef/W[1 3 1]>>stream Study Treatment 1 Treatment 2 With progressive success (left path) theoretical expectations mature, clarifying when replicability is expected. A degenerative research program (the right path) persistently fails to replicate the findings and progressively narrows the universe of conditions to which the claim could apply. It seems that my earlier comment about me knowing about the replications mentioned above being due to “unusually large numbers of highly powered studies” has some truth to it. As an exercise , I ask students to fill out the first section of the replication recipe with an article that I assign (I pre-selected two articles that are short and have a relatively simple research design). Thanks Ellen and Rolf! Will update post later (possible w more replication papers), thanks :), Very nice post and congrats on getting the paper published. Shanks, D.R.,Newell,B.R., Lee, E.H., Balakrishnan, D., Ekelund, L., Cenac,Z. With repeated failures (right path) the generalizability and replicability space both shrink, eventually to a theory so weak that it makes no commitments to replicability. This trenchant study analyzes the rise and decline in the quality and format of science in America since World War II. Science-Mart attributes this decline to a powerful neoliberal ideology in the 1980s which saw the fruits of scientific ... This does not imply that the magnitude of belief change is symmetrical for “successes” and “failures.” Prior and existing evidence inform the extent to which replication outcomes alter beliefs. PLOS Biology provides an Open Access platform to showcase your best research and commentary across all areas of biological science. I also don’t see very many papers based on replication published in the social sciences. ( 2011). In a replication study, the researcher repeats a study using the same methods but employs different variables such as different subjects and situations. Bromodomain (BRD) proteins, known to regulate gene expression, switching particular genes on and off, also play key roles in repairing DNA damage, and … This is illustrated by a shrinking generalizability space in which the theory does not make clear predictions. Yes endstream endobj startxref Click to check out the SJDM website and browse the JDM journal. Replication is not about the procedures per se, but using similar procedures reduces uncertainty in the universe of possible units, treatments, outcomes, and settings that could be important for the claim. What is Replication? We do not replicate the finding in any of our studies. 0 Replication Articles. A copy of a Monet painting is an example of a replication. The term “conceptual replication” has been applied to studies that use different methods to test the same question as a prior study. More than 4,000 charter schools around the country operate as independent, “mom and pop” schools without the supports of charter management organizations (CMOs).1 These standalone schools, which make up 65% of charter schools nationally, are often deeply rooted in the local neighborhood or are designed to serve specific community needs.2For some successful independent schools, replicating – In fact, conducting a replication of a prior claim with a different methodology can be considered a milestone for theoretical and methodological maturity. > replication studies examples. Found inside – Page 165This was the case, for example, when Vaughan (1990) studied the ... Replication The replication logic in qualitative research is analogous to that of ... The generalizability space is large because of theoretical immaturity; there are many conditions in which the claim might be supported, but failures would not discredit the original claim. One is whether different methods developed for similar statistical tasks produce the same results. What are two types of replication? The repetition of the study procedures is an appealing definition of replication because it often corresponds to what researchers do when conducting a replication—i.e., faithfully follow the original methods and procedures as closely as possible. According to some (e.g., Cartwright 1991), theterms “replication”, “reproduction” and“repetition” denote distinct concepts, while others usethese terms interchangeably (e.g., Atmanspacher & Maasen 2016a).Different disciplines can have different understandings of these termstoo. Unfortunately, the study we replicated was published at the Personality and Social Psychology Bulletin (PSPB) so you might not be able to access that. This is the authoritative reference work in the field. An interdisciplinary set, it investigates the extensive history, design and methods of case study research. The purpose is to observe the variation expected in a test result under the normal operating conditions of the laboratory. Example of direct replication and conceptual replication of Asch's conformity experiment. Deciding whether studies are replications after observing the outcomes can leverage post hoc reasoning biases to dismiss “failures” as nonreplications and “successes” as diagnostic tests of the claims, or the reverse if the observer wishes to discredit the claims. Found inside – Page 138Cousens' (1997) study of contextual changes in minor league baseball provides an example of using replication logic in multiple-case study research. Replication definition is - answer, reply.

According to common understanding, replication is repeating a study’s procedure and observing whether the prior finding recurs [7]. Why Is Replication so Important in Psychology? When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings.
