'LexTALE stands for Lexical Test for Advanced Learners of English. It is intended for cognitive researchers studying participants with an advanced level of English as a second language in an experimental setting.'

The test does not impose any time constraints. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 3.5 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'lextale_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. itemnumber: the itemnumber of the currently presented testitem testitem: the currently presented testitem wordstatus: the wordstatus of the presented testitem: 1 = word; 0 = nonword //DVs: response: the participant's response: 'yes' vs. 'no' correct: accuracy of response: 1 = correct response; 0 = otherwise latency: the response latency (in ms); measured from: onset of testitem (2) Summary data file: 'lextale_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) Note: summary variables for testitems with itemnumber > 0 propCorrect: proportion correct across of testitems meanCorrRT: mean correct response time across testitems numberCorrectWords: number of correctly identified words numberCorrectNonwords: number of correctly identified nonwords HITrate: the hitrate for correctly identifying words FArate: the false alarm rate for incorrectly identifying nonwords as words //main DV: avg_percent_correct: averaged % correct. It is calculated as follows: ((number of words correct/40*100) + (number of nonwords correct/20*100)) / 2 * 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 testblock with 63 items of which the first three are practice items. Items (40 words/20 nonwords) are presented in a fixed sequence with no time-constraints. ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ downloaded from: http://www.lextale.com/ ___________________________________________________________________________________________________________________ INSTRUCTIONS ___________________________________________________________________________________________________________________ downloaded from: http://www.lextale.com/ ___________________________________________________________________________________________________________________ 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.
