The Amsterdam Mathematical Psychology Laboratory (AMPL Psych) is a research laboratory focused on understanding the cognitive processes that shape human behavior. Its work investigates decision making, response inhibition, language, attention, memory, and learning. AMPL brings together experimental research and quantitative approaches, with two broad areas of focus: developing mathematical and computational models of cognition, and applying cognitive psychology to practical problems.

The laboratory shares its research through academic publications, projects, workshops, and conferences. Its recent work covers topics including cognitive control, prospective memory, conflict processing, evidence accumulation, working memory, and individual differences. AMPL also develops and contributes to research software, including tools for Bayesian hierarchical cognitive modeling, supporting the analysis and interpretation of experimental data. By combining experiments, computational methods, and applied perspectives, the laboratory contributes to the study of how people think, learn, remember, and make decisions. Its website provides information about the team, publications, events, funding, software, and projects, offering researchers and interested readers an overview of the laboratory’s activities and findings.
