Reproducibility and Replicability in a Fast-Paced Methodological World

Changes and challenges: managing ADHD in a fast-paced world.

BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) impairs the lives of both children and adults. Undiagnosed and untreated, ADHD may have serious lifelong consequences. Research has identified diagnostic clues, neurotransmitter pathways, and psychiatric comorbidities related to ADHD, as well as effective pharmacologic, behavioral, and psychosocial interventions. Stimulant agents have b...

Replicability and Reproducibility in Comparative Psychology

Psychology faces a replication crisis. The Reproducibility Project: Psychology sought to replicate the effects of 100 psychology studies. Though 97% of the original studies produced statistically significant results, only 36% of the replication studies did so (Open Science Collaboration, 2015). This inability to replicate previously published results, however, is not limited to psychology (Ioan...

Reproducibility and replicability of rodent phenotyping in preclinical studies

The scientific community is increasingly concerned with the proportion of published "discoveries" that are not replicated in subsequent studies. The field of rodent behavioral phenotyping was one of the first to raise this concern, and to relate it to other methodological issues: the complex interaction between genotype and environment; the definitions of behavioral constructs; and the use of l...

Reproducibility vs. Replicability: A Brief History of a Confused Terminology

Replicability, Reproducibility, and Agent-based Simulation of Interventions

Secondary use of medical data and use of observational data for causal inference has been growing. Yet these data bring many challenges such as confounding due to unobserved variables and variation in medical processes across settings. Further, while methods exist to handle some of these problems, researchers lack ground truth to evaluate these methods. When a finding is not replicated across m...
