Explicit moments of decision times for single-and double-threshold drift-diffusion processes

V Srivastava, P Holmes, P Simen - Journal of Mathematical Psychology, 2016 - Elsevier
We derive expressions for the first three moments of the decision time (DT) distribution

Modeling simple decisions and applications using a diffusion model

R Ratcliff, P Smith - 2015 - academic.oup.com
The diffusion model is one of the major sequential-sampling models for two-choice decision-
making and choice response time in psychology. The model conceives of decision-making …

Modeling regularities in response time and accuracy data with the diffusion model

R Ratcliff, PL Smith, G McKoon - Current directions in …, 2015 - journals.sagepub.com
Diffusion models for simple two-choice decision making have achieved prominence in

Comparing fixed and collapsing boundary versions of the diffusion model

C Voskuilen, R Ratcliff, PL Smith - Journal of mathematical psychology, 2016 - Elsevier
Optimality studies and studies of decision-making in monkeys have been used to support a
model in which the decision boundaries used to evaluate evidence collapse over time. This …

Sequential sampling models with variable boundaries and non-normal noise: A comparison of six models

A Voss, V Lerche, U Mertens, J Voss - Psychonomic bulletin & review, 2019 - Springer
One of the most prominent response-time models in cognitive psychology is the diffusion
model, which assumes that decision-making is based on a continuous evidence …

Modeling evidence accumulation decision processes using integral equations: Urgency-gating and collapsing boundaries.

PL Smith, R Ratcliff - Psychological review, 2022 - psycnet.apa.org
Diffusion models of evidence accumulation have successfully accounted for the distributions

An introduction to the diffusion model of decision-making

PL Smith, R Ratcliff - An introduction to model-based cognitive …, 2023 - Springer
The diffusion model assumes that two-choice decisions are made by accumulating
successive samples of noisy evidence to a response criterion. The model has a pair of …

Diffusion decision model: Current issues and history

R Ratcliff, PL Smith, SD Brown, G McKoon - Trends in cognitive sciences, 2016 - cell.com
