Abstract
Two programs that can be used to determine the probability distributions of reaction times are detailed. The first program takes rank-ordered reaction times as input and outputs a file of quantized data. The second program uses a simplex procedure to estimate the parameters of the ex-Gaussian equation that provides the best description of the quantized data. The advantages of this type of data analysis are also discussed.
