This script implements a mental rotation task for children. The current version is optimized for tablet use/tablet size (e.g. ipads) used for iperson testing. A smartphone version optimized for remote testing is also available in the Millisecond Software library. ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are presented figures that carry a suitcase in either the left or right hand. Figures can show their front or back and can be right side up or up side down. Participants work through 4 practice problems with the test administrator before working on 32 problems on their own. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 5 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ DATA FILE INFORMATION: The default data stored in the data files are: (1) Raw data file: 'abcdlittlemantest_tablet_raw*.iqdat' (a separate file for each participant)* /testdate: the testdate information entered at the start of testing /id: the id entered at the start of testing /language: the selected language build: Inquisit build computer.platform: the platform the script was run on (win/mac/ios/android) date, time, subject, group, session: date and time script was run with the current subject/groupnumber/session number blockcode, blocknum: the name and number of the current block trialcode, trialnum: the name and number of the currently recorded trial (Note: not all trials that are run might record data; by default data is collected unless /recorddata = false is set for a particular trial/block) /lmt_stimulus_xx: stores the currently presented image file /lmt_stimulus_type_xx: 1 Backward Down Left 2 Backward Down Right 3 Backward Up Left 4 Backward Up Right 5 Forward Down Left 6 Forward Down Right 7 Forward Up Left 8 Forward Up Right /lmt_correctButton_xx: stores the correct location of the suitcase: 0 = left; 1 = right response: stores the response button pressed: "leftbutton" vs. "rightbutton" vs. 0 => no response (Inquisit default response variable) /lmt_button_pressed_xx: stores the response button pressed: 0 = "left"; 1 = "right"; or "timedout" (custom response variable) /lmt_correct_xx: accuracy of response: 1 = correct response; 0 = otherwise (wrong selection or timeout) /lmt_RT_xx: the response latency (in ms); measured from: onset of images until response or timeout Note: timeout latencies are stored as -1 /homeButtonRT: the time (in ms) that it took to press the green home Button during trial.iti (2) Summary data file: 'abcdlittlemantest_tablet_summary*.iqdat' (a separate file for each participant)* /testdate: the testdate information entered at the start of testing /id: the id entered at the start of testing /language: the selected language inquisit.version: the version of Inquisit script.startDate: date script was run (local date for participant) script.startTime: time script was started (local time for participant) script.subjectId: subject id number script.groupId: group id number script.sessionId: session id number script.elapsedTime: time it took to run script (in ms) script.completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) lmt_scr_assess_date: currently simply stores the script.startDate (the local time is stored under script.startTime) lmt_src_prop_correct: proportion of correct responses lmt_scr_num_correct: absolute number of correct responses lmt_scr_num_wrong: absolute number of (active) error responses lmt_scr_num_timed_out: absolute number of timeout (passive) errors. lmt_scr_avg_RT: average response time of correct and incorrect selections Note: timeouts latencies are excluded from this variable lmt_scr_rt_correct: average only correct RT; calculation (Mean latency for correct =1) lmt_scr_rt_wrong: average only wrong RT (= latencies of incorrect selections); Note (KB): timeout errors are excluded lmt_scr_efficiency: Accuracy/ Reaction Time; calculation (lmt_src_prop_correct/lmt_scr_rt_correct) /lmt_stimtype1_correct_rt- /lmt_stimtype8_correct_rt: latency of correct selections by stimulus type (1-8) /lmt_stimtype1_num_correct- /lmt_stimtype8_num_correct: number of correct selections by stimulus type (1-8) /lmt_stimtype1_wrong_rt- /lmt_stimtype8_wrong_rt: latency of error selections by stimulus type (1-8) /lmt_stimtype1_num_wrong- /lmt_stimtype8_num_wrong: number of error selections by stimulus type (1-8) /lmt_stimtype1_num_timed_out- /lmt_stimtype8_num_timed_out: number of timed-out selection trials by stimulus type (1-8) * 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 ___________________________________________________________________________________________________________________ - 1 demo problem (if incorrect, it can be repeated as often as necessary); no response deadline - 3 additional practice problems - demo and practice problems are presented in a fixed order - 32 test problems (presented in fixed order) Trial Sequence: homebutton needs to be pressed (changes color from white to gray) -> ITI: 1500ms -> stim (until response or timeout at 5s) -> Note: practice trials The error feedback is presented for at least 1000ms regardless of whether the home button is pressed beforehand or not. ITI is started only if the home button was pressed. ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ provided by ABCD Consortium, see section Editable Stimuli ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ provided by ABCD Consortium, 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: /picSize: the proportional size of the little man images (default: 60%) /responsebuttonSize: the proportional size of the response buttons (default: 8%) /ITI: the duration (in ms) of the intertrial interval (default: 1500ms) /readyDuration: the duration (in ms) of the ready trial (default: 3000ms) /responseDeadline: a response deadline in ms (default: 5000ms) /scriptlastupdate: should store the date of the last change made to the script
