Speed–accuracy trade-off in plants

Psychonomic Bulletin & Review, 2020
Speed-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

Retest Reliability of Integrated Speed–Accuracy Measures

Assessment, 2021
Cognitive 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.

Slowness and age: Speed-accuracy mechanisms.

Psychology and Aging, 1995
Young 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.

Speed–accuracy trade-offs in myocontrol

Human Movement Science, 2006
Myoelectric (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.

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 ...

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.

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.

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 optimization for skill learning

2009 IEEE International Conference on Robotics and Automation, 2009
Robot 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 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
