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.

Ethanol, errors, and the speed–accuracy trade-off
Pharmacology Biochemistry and Behavior, 2001Ethanol 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.

Adult age and the speed-accuracy trade-off
Ergonomics, 1979Three experiments were conducted to investigate the possibility that previously reported age differences in speed of performance were caused by older subjects placing more emphasis on accuracy than younger subjects. The speculation that older subjects generally have a greater emphasis on accuracy was confirmed, but only in one of the experiments was ...

Speed–Accuracy Trade-Off in Voluntary Postural Movements
Motor Control, 2005We investigated the speed and accuracy of fast voluntary movements performed by the whole body during standing. Adults stood on a force plate and performed rhythmic postural movements generating fore and back displacements of the center of pressure (shown as online visual feedback). We observed that for the same target distance, movement time increased

Letter matching in the hemispheres: Speed-accuracy trade-offs
Neuropsychologia, 1992Eight subjects performed physical and nominal letter-matching tasks for pairs of letters presented in the left, right, or central visual fields, using a unimanual two-choice response-time paradigm. Latencies were manipulated by using a cued response procedure, and speed-sensitivity and speed-bias functions were calculated separately for each of the ...

Speed/accuracy trade-offs in target-directed movements
Behavioral and Brain Sciences, 1997This target article presents a critical survey of the scientific literature dealing with the speed/accuracy trade-offs in rapid-aimed movements. It highlights the numerous mathematical and theoretical interpretations that have been proposed in recent decades.

Effect of mental fatigue on speed–accuracy trade-off
Neuroscience, 2015The aim of this study was to investigate the effects of mental fatigue on the duration of actual and imagined goal-directed arm movements involving speed-accuracy trade-off. Ten participants performed actual and imagined point-to-point arm movements as accurately and as fast as possible, before and after a 90-min sustained cognitive task inducing ...

Speed-Accuracy Trade-Off in Recognition Memory
Science, 1973In a recognition memory experiment, the time allowed for retrieval was controlled by using the offset of the probe as a signal to terminate retrieval and respond. The response latencies measured in the experiment indicate that this procedure effectively eliminated fast-guess strategies. The recognition signal-to-noise ratio, d

Where in the world is the speed/accuracy trade-off?
Behavioral and Brain Sciences, 1997Even though Plamondon's kinematic model fits the data well, we do not share the view that it explains movements other than ballistic ones. The model does not account for closed-loop control, which is the more common type of movement in everyday life, nor does it account for recent data indicating interference with ongoing processing.

A mathematical description of the speed/accuracy trade-off of aimed movement
Proceedings of the 2015 British HCI Conference, 2015Target clicking having proved an indispensable building block of interface design, it is little surprise that the speed/accuracy trade-off of aimed movement has always been a keen concern of HCI research. The trade-off is described by the Fitts law. In HCI and psychology likewise, the traditional approach has focused on the time-minimisation paradigm ...
