PAL Total Errors 12 Shapes (Adjusted): The number of times the subject chose the incorrect box for a stimulus on assessment problems, where the number of shapes was equal to 12 (PALTE12), plus an adjustment for the estimated number of errors they would have made on any other 12 pattern problems, attempts and recalls they did not reach.

KEY: PAL Total Errors (Adjusted): The number of times the subject chose the incorrect box for a stimulus on assessment problems (PALTE), plus an adjustment for the estimated number of errors they would have made on any problems, attempts and recalls they did not reach. This measure allows you to compare performance on errors made across all subjects regardless of those who terminated early versus those completing the final stage of the task. In this task variant PALTEA does not include 12 box level to provide a direct comparison to Recommended Standard. 




paltea4 
Integer 

Recommended 
PAL Total Errors 4 Shapes (Adjusted): The number of times the subject chose the incorrect box for a stimulus on assessment problems, where the number of shapes was equal to 4 (PALTE4), plus an adjustment for the estimated number of errors they would have made on any other 4 pattern problems, attempts and recalls they did not reach. 




otslc6sd 
Integer 

Recommended 
OTS Latency to Correct Standard Deviation (SD) (6 move): The standard deviation of the response latencies, calculated from the appearance of the stocking balls until the correct box choice was made, for problems where 6 moves was the solution. Calculated across trials where 6 moves was the correct answer. 




paltea6 
Integer 

Recommended 
PAL Total Errors 6 Shapes (Adjusted): The number of times the subject chose the incorrect box for a stimulus on assessment problems, where the number of shapes was equal to 6 (PALTE6), plus an adjustment for the estimated number of errors they would have made on any other 6 pattern problems, attempts and recalls they did not reach. 




paltea8 
Integer 

Recommended 
PAL Total Errors 8 Shapes (Adjusted): The number of times the subject chose the incorrect box for a stimulus on assessment problems, where the number of shapes was equal to 8 (PALTE8), plus an adjustment for the estimated number of errors they would have made on any other 8 pattern problems, attempts and recalls they did not reach. 




sstdeg 
Integer 

Recommended 
SST Direction Errors: Go Trials: The total number of trials where the subject pressed the wrong button to the direction of the arrow stimulus on a Go trial. 




sstdes 
Integer 

Recommended 
SST Direction Errors: Stop Trials: The total number of trials where the subject pressed the wrong button to the direction of the arrow stimulus on a Stop trial. 




sstfsg 
Integer 

Recommended 
SST Failed Stop RT Go RT: A comparison between the reaction times on Go trials versus those on a Failed Stop trial. Research suggests that the Failed stop reaction time should be shorter than the Go reaction time. This measure is reported as Yes = 1, No = 0. Subjects should output 'yes' in ideal situations.You would hope to see the mean reaction time from all the assessed Failed Stop trials being less than (faster) the mean reaction time from all assessed Go trials. 




sstmfrti 
Integer 

Recommended 
SST Mean Failed Stop RT Increases: The assessed Failed Stop reaction times are ordered and then the mean of the 10 trials with the shortest Stop Signal Delay (SSD) is compared to the mean of the 10 trials with the longest SSD. The Failed Stop reaction time should increase as the SSD increases. This measure is reported as Yes = 1, No = 0.

KEY: SST Stop Signal Reaction Time: The estimate of time where an individual can successfully inhibit their responses 50% of the time. This covert measurement is sampled from the 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. We can infer that this is the time before which all actions become ballistic and the subject is no longer able to cancel their action selection.
