Slowness and age: Speed-accuracy mechanisms.
Psychology and Aging, 1995Young and older adults' mechanisms of trial-by-trial control of accuracy and choice reaction times (RTs) were compared in 2,000 trials. With equal mean error rates, the older group's correct and error RT were longer, and their within-subject distribution was a linear function of the younger group's.

The study investigated the speed-accuracy trade for detecting a weak 1000-Hz tone presented in continuous noise. Reaction times were measured in a YES-NO design with a fixed response deadline and various payoffs for the four stimulus-response combinations. The deadline was varied from 300 to 2000 msec in various experiments, and the payoff schedule was

Speed–accuracy trade-off in plants
Psychonomic Bulletin & Review, 2020Speed-accuracy trade-off (SAT) is the tendency for decision speed to covary with decision accuracy. SAT is an inescapable property of aimed movements being present in a wide range of species, from insects to primates. An aspect that remains unsolved is whether SAT extends to plants' movement. Here, we tested this possibility by examining the swaying in

Speed-accuracy optimization for skill learning
2009 IEEE International Conference on Robotics and Automation, 2009Robot motor capability is crucial for skill learning because it determines how accurately and rapidly a robot can perform a skill to accomplish a task constrained by the spatial and temporal conditions. Due to the capability of robot motor, a robot may not be able to perform skills to satisfy both task spatial and temporal constraints. To determine the

Speed–accuracy trade-offs in myocontrol
Human Movement Science, 2006Myoelectric (EMG) signals are used in assistive technology for prostheses, computer and domestic control. However, little is known about the capacity of controlling these signals. Specifically, it is unclear whether myocontrol, i.e., the control of myoelectric signals, obeys the same laws as motor control.

Fitts' throughput and the speed-accuracy tradeoff
Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2008We describe an experiment to test the hypothesis that Fitts' throughput is independent of the speed-accuracy tradeoff. Eighteen participants used a mouse in performing a total of 5,400 target selection trials. Comparing nominal, speed-emphasis, and accuracy-emphasis conditions, significant main effects were found on movement time (ms) and error rate (%)

Retest Reliability of Integrated Speed–Accuracy Measures
Assessment, 2021Cognitive tasks borrowed from experimental psychology are often used to assess individual differences. A cardinal issue of this transition from experimental to correlational designs is reduced retest reliability of some well-established cognitive effects as well as speed–accuracy trade-off.

Speed–accuracy tradeoffs in specialized keyboards
International Journal of Human-Computer Studies, 2011Patients with locked-in syndrome are perceptually and cognitively aware of their environment but are unable to speak and have very limited motor capabilities. These patients frequently use a virtual keyboard with a cursor that moves over different items. The user triggers a selector when the cursor is over the desired item. For text entry such a method

Modulating speed-accuracy strategies in major depression
Journal of Psychiatric Research, 2015Depression is associated with deficits in cognitive flexibility. The role of general slowing in modulating more specific cognitive deficits is however unclear.We assessed how depression affects the capacity to strategically adapt behavior between harsh and prudent response modalities and how general and specific processes may contribute to performance ...

Speed–accuracy tradeoffs in animal decision making
Trends in Ecology & Evolution, 2009The traditional emphasis when measuring performance in animal cognition has been overwhelmingly on accuracy, independent of decision time. However, more recently, it has become clear that tradeoffs exist between decision speed and accuracy in many ecologically relevant tasks, for example, prey and predator detection and identification; pollinators ...
