Note: script checks for a touchscreen - aborts script if no touchscreen is detected ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are asked to use their fingers of either the left or your right hand to drum sequences on their touchscreen. 3 versions: for all 3 versions, participants are asked to adjust the screen position of 4 buttons (one button for index finger, middle finger, ring finger and pinky each). Version 1: tap 4 buttons in sequence, starting with index finger to pinky. Timelimit enforced. Version 2: tap 4 buttons in sequence, starting with pinky to index finger. Timelimit enforced. Version 3: tap any of the 4 buttons in a (randomly) selected sequence. Timelimit enforced. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 12 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'fingerdrummingtask_raw*.iqdat' (a separate file for each participant)* build: The specific Inquisit version used (the 'build') that was run computer.platform: the platform the script was run on (win/mac/ios/android) date, time: date and time script was run subject, group: with the current subject/groupnumber session: with the current session id blockcode, blocknum: the name and number of the current block (built-in Inquisit variable) trialcode, trialnum: the name and number of the currently recorded trial (built-in Inquisit variable) Note: trialnum is a built-in Inquisit variable; it counts all trials run; even those that do not store data to the data file. hand: 1 = Left Hand (LH); 2 = Right Hand (RH) version: 3 versions: 1 vs. 2 vs. 3 Test: 1 = timed test; 0 = untimed practice (first 3 sequences) countTaps: a tap counter index: helper variable to determine the current tap in the sequence (index of the current tapsequence list) nextIndex: helper variable to determine the next tap in the sequence currentButton: stores the number of the current button in the sequence: 4 = pinky 3 = ring 2 = middle 1 = index response: the participant's response correct: accuracy of response: 1 = INITIAL correct response; 0 = otherwise latency: the response latency (in ms) of the current latency (correct latency) (for initially incorrect responses, latency will include an error adjustment penalty) countCompletedSequences: a counter of how many sequences were completed buttonSize: helper variable that stores the current button size (in percentage) (2) Summary data file: 'fingerdrummingtask_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) 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) Version1: LH_completedSequences_V1: stores the number of completed sequences for left hand version1 LH_ACC_V1: stores the proportion correct taps for left hand version1 LH_meanRT_V1: stores the mean latency (in ms) of correct taps in non-error trials for left hand version1 RH_completedSequences_V1: stores the number of completed sequences for right hand version1 Note: speed and accuracy are necessary for a high number of completed sequences RH_ACC_V1: stores the proportion correct taps for right hand version1 RH_meanRT_V1: stores the mean latency (in ms) of correct taps in non-error trials for right hand version1 Version2: LH_completedSequences_V2: stores the number of completed sequences for left hand version2 LH_ACC_V2: stores the proportion correct taps for left hand version2 LH_meanRT_V2: stores the mean latency (in ms) of correct taps in non-error trials for left hand version2 RH_completedSequences_V2: stores the number of completed sequences for right hand version2 Note: speed and accuracy are necessary for a high number of completed sequences RH_ACC_V2: stores the proportion correct taps for right hand version2 RH_meanRT_V2: stores the mean latency (in ms) of correct taps in non-error trials for right hand version2 Version3: LH_completedSequences_V3: stores the number of completed sequences for left hand version3 LH_ACC_V3: stores the proportion correct taps for left hand version3 LH_meanRT_V3: stores the mean latency (in ms) of correct taps in non-error trials for left hand version3 RH_completedSequences_V3: stores the number of completed sequences for right hand version3 Note: speed and accuracy are necessary for a high number of completed sequences RH_ACC_V3: stores the proportion correct taps for right hand version3 RH_meanRT_V3: stores the mean latency (in ms) of correct taps in non-error trials for right hand version3 * separate data files: to change to one data file for all participants (on Inquisit Lab only), go to section "DATA" and follow further instructions ___________________________________________________________________________________________________________________ EXPERIMENTAL SET-UP ___________________________________________________________________________________________________________________ 2 hands: order of left-right hand is counterbalanced by groupnumber odd groupumbers: run right hand first even groupnumbers: run left hand first Participants are asked to adjust the size of the response buttons at the start of the task (Note: a min = 5% and max = 18% sizeare enforced). Participants are asked to adjust the screen position of 4 buttons (one button for index finger, middle finger, ring finger and pinky each) for each hand. blocks run in random order (to change order go to section EXPERIMENT) All versions start off with a practice run. After completion of 3 sequences, the task starts with the appearance of a timer. Version 1: tap 4 buttons in sequence, starting with index finger to pinky. Timelimit of 1 minute (default) enforced Version 2: tap 4 buttons in sequence, starting with pinky to index finger. Timelimit of 1 minute (default) enforced. In both versions, an incorrect tap highlights the missed button which needs to be pressed in order to move ahead in the sequence Version 3: tap any of the 4 buttons in a (randomly) selected sequence. The selected button is highlighted in yellow. An incorrect button press presents feedback and alerts participants that they have to press the highlighted button to move ahead. Timelimit of 1 minute (default) enforced. ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ buttons appear gray on black with black finger labeling. Size of buttons can be adjusted under section Editable Parameters. ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under 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: /buttonSize: the size of the response buttons in proportion to canvas height at script start (default: 10%) /timeoutV1: the time limit (in ms) for version 1 (default: 60000ms) /timeoutV2: the time limit (in ms) for version 2 (default: 60000ms) /timeoutV3: the time limit (in ms) for version 3 (default: 60000ms) /correctSequenceV1: stores the correct sequence for version 1 (starting at index: 1 to pinky: 4) /correctSequenceV2: stores the correct sequence for version 2 (starting at pinky: 4 to index: 1)
