The trial making test is an executive function test of visual attention and task switching. The script only runs on screens that are at least W:L = 118mm : 153mm (Note: ios and Android devices force a vertical layout for this script) References: Armitages, S. G.

Thus, trialnum may not reflect the number of main trials run per block. startDotNumber: specifies the current dot that participant is on targetDotNumber: specifies the current dot that needs to be connected next sampleAErrors: counts the errors made on SampleA Trail trail1Errors: counts the errors made on Trail1 sampleBErrors: counts the errors made on SampleB Trail trail2Errors: counts the errors made on Trail2 errortrail_samplea- errortrail_trail2: saves all missed circles in the order made for each trail separately sampleATime: time (in ms) spent on SampleA Trail trail1Time: time (in ms) spent on Trail1 sampleBTime: time (in ms) spent on SampleB Trail trail2Time: time (in ms) spent on Trail2 (2) Summary data file: 'trailmakingtest_summary*.iqdat' (a separate file for each participant) inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) computer.touch: 1 = the current screen is a touchscreen; 0 = the current screen is not a touchscreen startDate: date script was run startTime: time script was started subjectid: assigned subject id number groupid: assigned group id number sessionid: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) //screen data: ScreenOK: 0 = screen is not big enough (script should terminate); 1 = screen is big enough screenWidthMM: the width of the current screen in mm screenHeightMM: the height of the current screen in imm //parameter settings: parameters.runA: true = the script runs SampleA/Trail1 false = the script does NOT runs SampleA/Trail1 parameters.runB: true = the script runs SampleB/Trail2 false = the script does NOT runs SampleB/Trail2 //summary data: sampleAErrors: counts the errors made on SampleA Trail sampleATime: time (in ms) spent on SampleA Trail sampleBErrors: counts the errors made on SampleB Trail sampleBTime: time (in ms) spent on SampleB Trail trail1Errors: counts the errors made on Trail1 trail1Time: time (in ms) spent on Trail1 trail2Errors: counts the errors made on Trail2 trail2Time: time (in ms) spent on Trail2 combined_errors: adds errors made on all 4 trails combined_trailtime: combines the time (in ms) it took all 4 trails ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ This script runs 4 trails (sampleA, trailA, sampleB, trailB) Note: this script allows researchers to selectively run only one of the tasks if needed. Check Editable Parameters: parameters.runA and parameters.runB By default, this script runs both tasks ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ are provided in the included scripts ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ see section Editable Instructions ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment. The parameters you can change are: check below for (relatively) easily editable parameters, stimuli, instructions etc. Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment. /showTestErrorFeedback: true = a yellow halo is presented over the correct circle (default) false = no extra errorfeedback is given (incorrect path is still erased however) / runA: true = the script runs SampleA/Trail1 false = the script does NOT runs SampleA/Trail1 / runB: true = the script runs SampleB/Trail2 false = the script does NOT runs SampleB/Trail2
