Developmental research—especially with infant participants—also has discipline-specific replicability challenges, including small samples and limited measurement methods. Inspired by collaborative replication efforts in cognitive and social psychology, we describe a proposal for assessing and promoting replicability in infancy research: large-scale, multi-laboratory replication efforts aiming for a more precise understanding of key developmental phenomena. The ManyBabies project, our instantiation of this proposal, will not only help us estimate how robust and replicable these phenomena are, but also gain new theoretical insights into how they vary across ages, linguistic communities, and measurement methods. This project has the potential fora variety of positive outcomes, including less-biased estimates of theoretically important effects, estimates of variability that can be used for later study planning, and a series of best-practices blueprints for future infancy research.  \nTHE “REPLICATION CRISIS” AND ITS IMPACT IN DEVELOPMENTAL  \nPSYCHOLOGY  \nWhat can we learn from a single study? The ideal of scientific progress is that we accumulate progressively more precise measurements and integrate these into theories whose coverage grows broader and whose predictions become more accurate (Kuhn, 1962; Popper, 1963) . On this kind of model, a single study contributes to the broader enterprise by adding one set of measurements with known precision and stated limitations. Then further studies can build on this result, reusing the method and expanding its scope, adding precision, and generally contributing to a cumulative picture of a  \nA COLLABORATIVE APPROACH TO INFANT RESEARCH 3  \nparticular area of interest. Unfortunately, recent developments have cast doubt on whether research in psychology—and perhaps in other fields of inquiry as well—conforms to this model of cumulativity (Ioannidis, 2005, 2012) . For example, a large-scale attempt to reproduce 100 findings from high-profile psychological journals found that fewer than half of these were successful (Open Science Collaboration (OSC), 2015; cf. Gilbert, King, Pettigrew, & Wilson, 2016; Anderson et al., 2016) .  \nThere are many hypothesized sources for failures to replicate. First, any measurement includes some amount of random noise leading to variations in the outcome even i","cbCaitMPVb4iEFwY","https://ap.wps.com/l/cbCaitMPVb4iEFwY","pdf",221075,15,"English","# A Collaborative Approach to Infant Research\n## The “Replication Crisis” and Its Impact in Developmental Psychology","[{\"question\":\"Why is reproducibility harder in developmental psychology, especially with infants?\",\"answer\":\"Infant studies often rely on small samples due to recruitment and testing constraints, have difficulty maintaining consistent measurement, and use limited response measures that vary across participants and age groups.\"},{\"question\":\"What factors can cause failures to replicate published psychological findings?\",\"answer\":\"Random measurement noise, low statistical power, contextual differences that affect behavioral measurement, and questionable research practices such as undisclosed analytic flexibility and selective publication can all contribute.\"},{\"question\":\"What is the core proposal for improving replicability in infancy research?\",\"answer\":\"Large-scale, multi-laboratory replication efforts designed to more precisely estimate how robust key developmental phenomena are and to compare results across ages, linguistic communities, and measurement methods.\"},{\"question\":\"What benefits does the ManyBabies project aim to provide?\",\"answer\":\"The project seeks less-biased estimates of theoretically important effects, variance estimates useful for later study planning, and best-practices blueprints to guide future infancy research.\"}]","A Collaborative Approach to Infant Research - Promoting Reproducibility, Best Practices, and Theory-Building | PDF",38]
