Borchert (katjab@millisecond.com) for Millisecond Software, LLC Script Copyright © 02-16-2022 Millisecond Software ___________________________________________________________________________________________________________________ BACKGROUND INFO ___________________________________________________________________________________________________________________ This script implements a simple Anagram Test procedure ___________________________________________________________________________________________________________________ TASK DESCRIPTION ___________________________________________________________________________________________________________________ Participants are asked to solve 5 easy and 5 difficult anagrams (order of easy and difficult anagrams is fixed). They have 2 minutes per anagram and can enter as many solutions as they want during that time frame. A correct solution will terminate the current anagram and automatically present the next one. If participants run out of time, the next anagram is presented automatically. Participants can skip any anagram at any point, by entering 'SKIP' into the textbox. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes approx. 7 minutes. ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'anagramtask_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. ***built-in Inquisit variables: Note that in this script, only the trial.easyAnagramData/trial.difficultAnagramData store data to the data files. These trials do not collect responses. All other trials are set to /recorddata = false. response: the participant's response (scancode of response buttons) correct: accuracy of response: 1 = correct response; 0 = otherwise latency: the response latency (in ms); measured from: ***custom variables anagramCondition: 'easy' vs. 'difficult anagramIndex: the itemnumber of the current anagram anagram: the presented anagram suggestedSolutions: collects all suggested solutions for an anagram lastSuggestedSolution: the last suggested solution Note: if a participant enteres 'SKIP', the last suggested solution will be empty by default (however suggestedSolutions will contain all suggested solutions collected up to this point) correctSolution: the correct solution for each anagram anagramACC: 1 = final suggested solution is correct; 2 = final suggested solution is incorrect anagramRT: the cumulative time (in ms) that participants spent on solving each anagram skip: 1 = participant entered 'SKIP' into the textbox; 0 = participant did not enter 'SKIP' countAttempts: the number of suggested solutions per anagram (2) Summary data file: 'anagramtask_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) countSkips_easy: counts the number of times participant entered 'SKIP' for an easy anagram meanAttempts_easy: mean number of solutions provided for easy anagrams (includes anagrams that were 'skipped' at some point) propCorrect_easy: proportion correctly solved easy anagrams meanRT_easy: mean time (ms) participant spent on easy anagrams meanCorrRT_easy: mean time (ms) participant spent on easy anagrams that were solved correctly (same for difficult anagrams) * 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 ___________________________________________________________________________________________________________________ Anagram 1, 2, 5, 8, 10 randomly sample without replacement from the 5 easy anagrams. Anagram 3, 4, 6, 7, 9 randomly sample without replacement from the 5 difficult anagrams. Eachh anagram has 2 minutes. => if participant enters an incorrect solution: feedback is given, the last suggested solution is cleared out and participant can make another attempt => if participant enters the correct solution: feedback is given and the next anagram is presented automatically => if participant runs out of time: the next anagram is automatically provided with the note 'ok - let's try this one instead' => if participant enters 'skip' at any point: no feedback is provided and the next anagram is presented immediately ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ provided by Millisecond Software - can be edited under section Editable Stimuli ___________________________________________________________________________________________________________________ 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.
