The time course of perceptual choice: The leaky, competing accumulator model.

Usher, Marius, McClelland, James L.·2001·Psychological Review

Abstract

The time course of perceptual choice is discussed in a model of gradual, leaky, stochastic, and competitive information accumulation in nonlinear decision units. Special cases of the model match a classical diffusion process, but leakage and competition work together to address several challenges to existing diffusion, random walk, and accumulator models. The model accounts for data from choice tasks using both time-controlled (e.g., response signal) and standard reaction time paradigms and its adequacy compares favorably with other approaches. A new paradigm that controls the time of arrival of information supporting different choice alternatives provides further support. The model captures choice behavior regardless of the number of alternatives, accounting for the log-linear relation between reaction time and number of alternatives (Hick's law) and explains a complex pattern of visual and contextual priming in visual word identification.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The process involves a race between a mechanism that accumulates evidence for right, and against left, and a process that integrates evidence for left, and against right.

    “The process involves a race between a mechanism that accumulates evidence for right, and against left, and a process that integrates evidence for left, and against right (Usher and McClelland, 2001; Mazurek et al., 2003).”

  • The hypothesis that the bounded accumulation framework applies to decisions among 4 choices was suggested by theorists but had not been tested.

    “This hypothesis was suggested by theorists5,28,29 but had not been tested.”

  • In human studies, mean reaction times typically range from tens of milliseconds to about a second in simple perceptual tasks.

    “In human studies, mean RTs typically range from tens of milliseconds to about a second in simple perceptual tasks (Luce, 1986; Usher and McClelland, 2001).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
