There are few behavioral effects as ubiquitous as the speed-accuracy tradeoff (SAT). From
insects to rodents to primates, the tendency for decision speed to covary with decision …

The diffusion decision model allows detailed explanations of behavior in two-choice
discrimination tasks. In this article, the model is reviewed to show how it translates …

Many but not all cognitive abilities decline during ageing. Some even improve due to lifelong
experience. The critical capacities of attention and executive functions have been widely …

The dominant paradigm for inference in psychology is a null-hypothesis significance testing
one. Recently, the foundations of this paradigm have been shaken by several notable …

Abstract Stochastic diffusion models (Ratcliff, 1978) can be used to analyze response time
data from binary decision tasks. They provide detailed information about cognitive …

The EZ-diffusion model for two-choice response time tasks takes mean response time, the
variance of response time, and response accuracy as inputs. The model transforms these …

A growing number of researchers use descriptive distributions such as the ex-Gaussian and
the shifted Wald to summarize response time data for speeded two-choice tasks. Some of …

In this article, the first explicit, theory-based comparison of 2-choice and go/no-go variants of
3 experimental tasks is presented. Prior research has questioned whether the underlying …

We evaluated age-related differences in the optimality of decision boundary settings in a
diffusion model analysis. In the model, the width of the decision boundary represents the …

Background Intraindividual variability in reaction time (RT) has received extensive
discussion as an indicator of cognitive performance, a putative intermediate phenotype of …
