摘要: Pieron (1914, 1920, 1952) demonstrated that simple reaction time (SRT) decays as a hyperbolic function of luminance in detection tasks. However, whether such relationship holds equally for choice (CRT) has been questioned (Luce, 1986; Nissen, 1977), at least when the task is not brightness discrimination. In two SRT and three CRT experiments, we investigated relates (RT) to stimulus intensity five levels covering entire mesopic range. The psychophysical experiments consisted detection, two-alternative forced (2 AFC) with spatial uncertainty, 2 AFC semantic categorization, orientation results showed mean RT increases complexity. exponents functions relating were found be similar different experiments. This finding indicates Pieron's law well SRT. It describes power intensity, exponents, regardless complexity task.
