Roger Ratcliff

Roger Ratcliff develops and applies mathematical models—especially the diffusion decision model—to understand how people make fast decisions and how those processes change with tasks like memory retrieval, numeracy, visual working memory, and driving. His work often combines behavioral experiments (accuracy and response times) with computational modeling to separate underlying cognitive processes, including how they are affected by aging. Students would likely engage in quantitative modeling of decision-making and memory tasks rather than purely descriptive behavioral research.

Publication output has been fairly steady over the last decade, rising slightly to a peak around 2022-2023 before a modest decline in 2024-2025.
