A power/exponential law of choice reaction time is proposed as an alternative to the classical Hick-Hyman's law and the Sternberg's law of memory search. A reanalysis of some experimental data, including those by Hick, Hyman and Sternberg, indicates that this alternative law provides at least as good fits to experimental data as do the Hick-Hyman's and Sternberg's laws. Some important implications of this finding are pointed out concerning the rate of change of information and the nature of the memory search process for the Sternberg's paradigm.
