Speed-accuracy trade-off

Figure 9.3. The speed-accuracy trade-off (SATO) curve on performance of tasks with elements of both reaction time and accuracy. The black line shows that performance tends to be either slow and accurate or fast and error-prone. The dotted line depicts an impairement in performance as a shift in SATO this can be observed as a cost in either (a) both speed and accuracy, (b) predominantly speed or (c) predominantly accuracy.

Spatial accuracy with time constraints—Identical to spatial accuracy except that, in addition to accuracy, speed of execution of task is also of importance. Because maximal performance capacities for accuracy and speed of movement cannot, in general, be realized simultaneously, the carrying out of such tasks must necessarily involve speed-accuracy trade-offs (Fitts, 1954 Fitts and Posner, 1967 Murata and Iwase, 2001 Battaglia and Schrater, 2007 Jax et al., 2007 Bye and Neilson, 2008). The extent to which accuracy is sacrificed for increased speed of execution, or vice versa, is dependent on the actual or perceived relative importance of accuracy and speed. 

Speed-accuracy trade-off A fundamental limit of human information-processing systems at any level of abstraction that is most likely due to a more basic limit in channel capacity that is, channel capacity can be used to achieve more accuracy at the expense of speed or to achieve more speed at the expense of accuracy.
