Covariates appearing in the model are evaluated at the following values: Age = 41.59 years, BMI = 26.78 kg/m2.
RTIFDMRT, Median duration between stimulus onset and release of button; RTIFMMT, Mean time taken to touch stimulus after button release; SWMBE, Between errors—number of times that a box in which a token has been previously found is revisited; SWMS, Number of distinct boxes used for the subject to begin new search for a token; PRMPCI, Number of correct responses made in immediate condition; PRMPCD, Number of correct responses made in delayed condition; ERTOMDRT, Median latency of response from stimulus onset to subject response; ERTTH, Number of correctly answered responses; ASTSWMD, Median latency of response in rule switching trials; ASTLCMD, Median latency of response on congruent trials; SSPFSL, Longest sequence successfully recalled—forward variant; SSPRSL, Longest sequence successfully recalled—reversed variant; PALTEA, Number of times incorrect box is chosen + adjusted estimated number of errors that would have been made on any problems, attempts, and recalls that were not reached; PALFAMS, Number of correct box choices made on first attempt; DMSPC, Percentage of assessment trials during which subject selected the correct box on their first box choice; DMSMDLAD, Median latency from the available choices being displayed to the subject choosing the correct choice; DMSPEGE, Reports the probability of an error occurring when the previous trial was responded incorrectly; RVPMDL, Median response latency during assessment sequence blocks where the subject responded correctly; RVPA, Measure of how good the subject is at detecting target sequences; SSTSSRT, Length of time between the go stimulus and the stop stimulus at which the subject is able to successfully inhibit their response on 50% of the trials; OTSPSFC, Number of assessment problems on which the first box choice made was correct.
