A computational model of cortical-striatal mediation of speed-accuracy tradeoff and habit formation emerging from anatomical gradients in dopamine physiology and reinforcement learning
… often conflict, decision making has an inherent “speed-accuracy tradeoff”. Presented here is a computational neural model of decision making, which incorporates neurobiological design principles that optimize this tradeoff via reward-guided transfers of control between two sensory processing …

An analysis of word generation by the left and right cerebral hemispheres : the effects of imposed speed-stress instructions
A left hemisphere advantage in response accuracy was obtained for an adjective gener a tion task independent of fluctuations in subjects' speed-accuracy criteria. This effect resulted despite the fact that stimuli were not repeated over trials and despite the controls taken to minimize eye movement …

Epistemic action and language : a cross-linguistic study
… actions are physical actions which increase the speed, accuracy, and/or robustness of internal computation by allowing cognitive work to be off-loaded to the environment, thus simplifying internal computation. Previous studies on epistemic action are limited in that they demonstrate that …

Development of quantitative tools for assessment of cerebellar dysfunction
… Extensive analysis of one of the tests using a speed/accuracy trade-off shows a correlation of 0.74 with existing scoring systems. The second involves modeling the cerebellar function in arm movement as a PID controller. Initial results show trends toward asymmetry, higher values for Gk₂₁ and …

Retrieval mechanisms in sentence comprehension
… language comprehension. Through the use of the Speed Accuracy Tradeoff (SAT) paradigm (Wickelgren, 1977), healthy young adults were studied for the use of parallel or serial search mechanisms to understand syntactically complex sentences with multiple embeddings. Systematically designed sentence …

The effects of structured variation in nectar standing crop on currency choice and optimal foraging by bumble bees
… or rewarding inflorescences as expected from a speed-accuracy trade-off, rather than maximizing their overall average return rate. This quantitative test of the MVT demonstrates the need to incorporate responses to variation within patches in models of forager behavior.

Wave propagation in finite element and mass-spring-dashpot lattice models
… Specifically, the error in the ultrasonic phase speed with variations in Poisson's ratio and angle of incidence is evaluated in each model of an isotropic elastic solid. With regard to phase speed, materials with constant N grid spaces per P-wavelength having Poisson's ratios between 0.0 and 0.25 …

Seeing systems and the beholding eye : computer-aided visions of the postwar British landscape
… general characteristics of mainframe computers (speed, accuracy, replicability, and economy) to define new ways of representing and measuring visual phenomena, and of comparing alternative visions of the country, using quantitative "facts." The result was a digital technology-seeing systems-that …
