TLDR
The latency operating characteristic (LOG), denned as the trade-off relation between reaction time (RT) and discrimination accuracy, is proposed as a measure of the perceptual process that is invariant over changes in decision strategies in RT tasks.Abstract:
The latency operating characteristic (LOG), denned as the trade-off relation between reaction time (RT) and discrimination accuracy, is proposed as a measure of the perceptual process that is invariant over changes in decision strategies in RT tasks. The LOC was computed from confusion matrices constructed from sets of trials on which the RT fell within a given range. The convergent validity of the LOC was supported by findings of a strong and consistent relation between speed and accuracy that was invariant under changes in stimulus and response probability. Several models of the underlying perceptual processes are discussed which lead to a good description of LOC by a set of straight lines.read more

Understanding and using the Implicit Association Test: I. An improved scoring algorithm.
TL;DR: The best-performing measure incorporates data from the IAT's practice trials, uses a metric that is calibrated by each respondent's latency variability, and includes a latency penalty for errors, and strongly outperforms the earlier (conventional) procedure.

Optimizing the use of information: strategic control of activation of responses.
TL;DR: The results suggest that expectancies about the relative utility of the information extracted during the parallel and focused phases determine which phase is used to activate responses.

On the time relations of mental processes: An examination of systems of processes in cascade.
TL;DR: In this paper, a cascade model is presented and it is shown to be compatible with the general form of the relation between time and accuracy in speed-accuracy trade-off experiments.

Speed-accuracy tradeoff and information processing dynamics
TL;DR: A combination of the mixed-design signal method supplemented by partitioning of reaction times appears to be the optimal method.

TL;DR: This paper reexamines the visual search process, and visual information processing more generally, from a perspective of the continuous flow of information and responses through the visual system.

TL;DR: This book discusses statistical decision theory and sensory processes in signal detection theory and psychophysics and describes how these processes affect decision-making.

High-Speed Scanning in Human Memory
TL;DR: When subjects judge whether a test symbol is contained in a short memorized sequence of symbols, their mean reaction-time increases linearly with the length of the sequence, implying the existence of an internal serial-comparison process.

Stimulus information as a determinant of reaction time.
TL;DR: In the typical reaction-time experiment, S's reaction time is greater when he has to respond differentially to one of two equally probable stimuli instead of to just one stimulus, but this becomes even more significant when looked at from the standpoint of modern communication theory.
