Individual differences in Fitts’ Law Performance

August 3, 2016

Fitts’ Law (JEP, 1954) is the most robust relation in all of motor performance, relating movement time, T, movement distance, D, and target precision, W, in the now famous T = a + bLog2 (2D/W).  This law characterizes averaged group behavior.  We have asked whether this relation can be used to classify individuals as reliably good or poor Fitts’ Law performers.  In our first two experiments we have shown that Fitts’ Law is capturing a general feature of human movement that produces correlated individual differences and as well we have discovered a degree of specificity such that the strength of the correlated individual differences is inversely related to the magnitude of index of difficulty differences.
