Fitts' throughput and the speed-accuracy tradeoff

Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, 2008
We 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 (%)

Speed–accuracy tradeoffs in specialized keyboards

International Journal of Human-Computer Studies, 2011
Patients 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

Speed–accuracy tradeoffs in animal decision making

Trends in Ecology & Evolution, 2009
The 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 ...

Modulating speed-accuracy strategies in major depression

Journal of Psychiatric Research, 2015
Depression 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 ...

The Developmental Roots of the Speed-Accuracy Trade-Off.

Journal of Experimental Psychology: Human Perception and Performance, 2005
The speed of adult reaching movements is lawfully related to the distance of the reach and the size of the target. The authors had 7-, 9-, and 11-month-old infants reach for small and large targets to investigate a possible relation between the emergence of this speed-accuracy trade-off and the improvements in infants' ability to pick up tiny objects ...

Speed, accuracy, and ease of recall

Journal of Verbal Learning and Verbal Behavior, 1972
Word lists were followed by semantic (category name) or positional (serial position) probes, and serial-position functions were assessed in terms of expended-processing capacity (EPC). EPC indicated the amount of processing consumed by the memory task and was measured as reaction time to light signals which coincided with specific events in the memory ...

Speed-Accuracy Characteristics of Saccadic Eye Movements

Journal of Motor Behavior, 1985
Speed-accuracy trade-off characteristic of horizontal saccadic eye movements were examined in this study. Unlike limb movements, saccadic eye movements are preprogrammed, unidimensional, and do not involve target impact. Hence, they provide an optimal test of the impulse variability account of the speed-accuracy trade-off in rapid movements.

Daily modulation of the speed–accuracy trade-off

Neuroscience, 2017
Goal-oriented arm movements are characterized by a balance between speed and accuracy. The relation between speed and accuracy has been formalized by Fitts' law and predicts a linear increase in movement duration with task constraints. Up to now this relation has been investigated on a short-time scale only, that is during a single experimental session,

Ethanol, errors, and the speed–accuracy trade-off

Pharmacology Biochemistry and Behavior, 2001
Ethanol has been shown to have a relatively greater effect on error rates in speeded tasks than temazepam, and this may be due to a differential effect on the speed-accuracy trade-off (SATO). This study used different instruction sets to influence the SATO.

Speed-Accuracy Tradeoff during Response Preparation

Research Quarterly for Exercise and Sport, 1990
The speed-accuracy operating curve was investigated in a movement precuing two- or four-choice reaction time task. Four levels of response preferences were manipulated with subject instructions and postresponse information: (a) accuracy, (b) reaction time latency, (c) accuracy and reaction time latency, and (d) no preference.
