A value < 3 only happens if participant repeatedly failed on level 3. MS: the MS, it's 0 until it's calculated at the end of a block. The last ML recorded represents the participant's actual ML. The ML is subject to change throughout all 14 trials. ML: the ML, it's 0 until participant recalls digit sequences correctly. TE_TT: the TE_TT, it's -1 until it's set (and once it's set it should not change anymore) TE_ML: the TE_ML, it's -1 until it's set (and once it's set it it should not change anymore) ProposedSolution: the entered digit sequenceĪCC: 1 = proposed solution is correct 0 = otherwiseĬon_errorcount: consecutive error count on the current level N: the number of digits presented in a trialĬountTrials: counts the trials run in the current assessmentĬorrectSolution: the correct digit sequence Note: trialnum is a built-in Inquisit variable it counts all trials run even those Trialcode, trialnum: the name and number of the currently recorded trial (built-in Inquisit variable) Subject, group: with the current subject/groupnumberīlockcode, blocknum: the name and number of the current block (built-in Inquisit variable) (1) Raw data file: 'digitspan_forward_raw*.iqdat' (a separate file for each participant)īuild: The specific Inquisit version used (the 'build') that was runĬatform: the platform the script was run on (win/mac/ios/android) The default data stored in the data files are: The default set-up of the script takes appr.
