bestPEST Details

Description: bestPEST is a tool for determining psychophysical (and neurophysiological) thresholds using parameter estimation by sequential testing. The used algorithm is a modification of the procedure published by H.R. Lieberman and A.P. Pentland in Behavior Research Methods and Instrumentation in 1982 "Microcomputer-based estimation of psychophysical thresholds: The Best PEST". Usage: The application works in the range of 0-100 (initial values can be set between 20 and 80). Hence the parameters estimated should be adjusted by appropriate transform in advance to work within the working range. The procedure can be set to cut-off after a certain number of trials. The cut-off for the routine will be enable after confidence limits of the routine reach 1% of the full working range, or after the minimum number of trials has been reached. Other adjustments to the bestPEST performance should be made with caution. The procedure can be logged and saved to file (bestPEST_log -folder in your default file storage) or easily send via e-mail. The logs can also be save in local database in you device for later preview or sharing. User can start the routine using different initialization modes, i.e. determining threshold without prior knowledge of the threshold value (between 20 and 80) using the default initial value determined in the settings, or by setting an initial value based on a good guess. The latter will reach confidence of 1% of the full working range a bit quicker. User can also restart the procedure or toggle a previous response. It is also possible to set the procedure to work so that only long-clicks can be used to mark a response or non-response to avoid accidental clicks. Properties: Determines psychophysical threshold Based on sequential testing Algorithm is widely used in determining neurophysiological and psychophysical thresholds Threshold-finding procedure can be logged and saved to a file Minimum and maximum number of trials can be set in the settings Default initial value for the threshold can be set in the settings Works within 0-100 working range Displays a graph of the process after threshold has been determined with sufficient confidence Possible to toggle a response during the process Easy-to-use Response time-stamps Share logs via e-mail or compatible software Store measurements to local database Free No adds Permissions: Requires permission to write to en external storage (used only for the log files created upon user request)
