Psychophysics generally relies on estimating a subject’s ability to perform a specific task as a function of an observed stimulus. For threshold studies, the fitted functions are called psychometric functions. While fitting psychometric functions to data acquired using adaptive sampling procedures (e.g., “staircase” procedures), investigators have encountered a bias in the spread (“slope” or “threshold”) parameter that has been attributed to the serial dependency of the adaptive data. Using… CONTINUE READING
