Microcomputer-based estimation of psychophysical thresholds: The Best PEST

摘要: A new, maximally efficient technique for measuring psychophysical thresholds (Pentland, 1980) has been implemented on the microcomputer. This PEST (parameter estimation by sequential testing) is most parameter possible, given that form of psychometric function known. The similar to but faster and more accurate than other staircase procedures may be applied whenever techniques are applicable. “Best PEST” easily micro-computer; a BASIC program Apple II which does so presented. Best compared with procedures, including one recently micro-computer (Corwin, Kintz, & Beaty, 1979).
