The highest reported human efficiencies in a number of tasks. Vision tasks are presented in light gray, auditory tasks in dark gray, and the single motor study (present results) in black. I, Recognizing three-dimensional (3D) objects in luminance noise (Tjan et al., 1995);II, 3D object classification (Liu et al., 1995); III, global direction of dynamic random dots (Watamaniuk, 1993); IV, heading judgements (Crowell and Banks, 1996); V, detection of complex signals as a function of signal bandwidth and duration (Creelman, 1961); VI, letter discrimination (Parish and Sperling, 1991); VII, coherent visual motion (Barlow and Tripathy, 1997);VIII, discrimination of random, time-varying auditory spectra (Lufti, 1994); IX, discrimination of tonal frequency distributions (Berg, 1990);X, discrimination of the amplitude of a spatial sinusoid (Burgess et al., 1981); XI, data from the present study. The efficiency reported in the present study is higher than those reported previously.
