#DIGIT SPAN TRIAL#

pair: the first (0) and second (1) trial at each string length.

I have a dataframe with 8 columns, where: I wish to calculate digit span as the outcome measure: the maximum string length at which participant’s repeated back the sequence in the correct order on 50% of trials (i.e., 1 out of the 2 trials). If the participant performs incorrectly on both trials at a specific span length the task is terminated. If the participant performs correctly on at least one of the two trials at a specific span length the string length is increased on the next trial. There are two trials at each string length. The task is designed so that the sequence to recall starts at a string length of 3 digits and continues up to 9 digits. Issue: calculating the outcome measure 'digit span' for a digit span task using R.ĭigit span task description: the participant is awarded one mark for each instance they correctly recall a sequence of digits.
