Towards a Falsifiable Framework for Theories in Psychological Science

Meta-rep项目旨在检查可复制性危机：在许多领域，用不同的样本重复实验并不能产生相同的结果。目前的建议主要集中在为什么会出现这种情况的问题上，同时集中在一个案例研究上，即发展性阅读障碍的因果理论。我们将确定和量化可能在理论层面(例如，术语规定不足)、方法层面(例如，衡量不力)和系统层面(例如，发表偏见)影响可复制性的因素。在最后一步中，我们的目标是在回归模型中使用我们新开发或实施的措施，以建立不同因素之间的相互关系，并确定它们对可复制性的相对贡献。在为模型选择适当的因变量时，我们还将考虑什么是可复制性以及如何将其量化。通过总结哪些变量最有可能影响可复制性，我们还将为未来关于潜在最有效的提高可复制性方法的因果研究提出建议。

The META-REP project aims to examine the Replicability Crisis: the finding that, in numerous fields, repeating an experiment with a different sample does not yield the same results. The current proposal aims to mainly focus on the question why this is the case, while focussing on a case-study, namely causal theories of developmental dyslexia. We will identify and quantify factors that may affect replicability on the theoretical level (e.g., underspecified terminology), methodological level (e.g., poor measurement) and systematic level (e.g., publication bias). In the last step, we aim to use our newly developed or implemented measures in a regression model, to establish both the inter-relationship of the different factors, and to determine their relative contribution to replicability. In selecting an appropriate dependent variable for the model, we will also consider what replicability is and how it can be quantified. By concluding which variables are most likely to affect replicability, we will also make suggestions for future causal studies about potentially the most effective ways to increase replicability.
