The original e-prime script is published at: http://fablab.yale.edu/page/assays-tools Project downloaded: pokemon_gonogo.zip The Inquisit implementation of this script is based on e-prime script 'Pokenogo.es'.

it counts all trials run; even those that do not store data to the data file. run: the run number runCount: the run counter trialCategory: g = go trial; ng = nogo trial number: number of go trials preceding the next nogo trial Example: g3 = go trial #3 before the next nogo trial ng3 = nogo trial with 3 preceding go trials itemnumber: the itemnumber of the currently presented pokemon stim: the image file of the currently presented pokemon response: the participant's response (scancode of response buttons) 57 = spacebar 0 = no response correct: accuracy of response: 1 = correct response; 0 = otherwise latency: the response latency (in ms); measured from: onset of image no response = entire stimDuration + iti (2) Summary data file: 'pokemon_gonogo_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) propCorrect_overall: overall proportion correct (across runs and trialtypes) hitRate_overall: the overall hitrate (across all go trials) hitRT_overall: the mean hit response time in ms (across all correct go trials) commissionRate_overall: the overall commission rate (across all nogo trials) commissionRT_overall: the mean commission response time in ms (across all incorrect nogo trials) //separate by nogo trialCategory: ng1-ng5 nogoTrials_ng1: the number of ng1 trials across all runs (default setup: 20) commissions_ng1: the number of commissions made in ng1 trials across all runs commissionRate_ng1: the ng1 commission rate across all runs commissionRT_ng1: the mean response time for commission errors in ng1 trials across all runs * 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 ___________________________________________________________________________________________________________________ 5 Runs: - Each run presents 14 nogo trials and 43 go trials (roughly a 1:3 ratio); total = 57 trials per run - the trial sequence for each run is fixed (see section Editable Lists) - each nogo trial is preceded by 1, 3, or 5 nogo trials ng1: nogo trials that are preceded by 1 go trial => 20 ng3: nogo trials that are preceded by 3 go trials => 20 ng5: nogo trials that are preceded by 5 go trials => 20 Trial Sequence: stimulus (for for 1000ms) Note: responseTimeout = 2000ms -> iti (for 3000ms) ___________________________________________________________________________________________________________________ STIMULI ___________________________________________________________________________________________________________________ taken from original e-prime script 'Pokenogo.es' http://fablab.yale.edu/page/assays-tools (converted to png files) ___________________________________________________________________________________________________________________ 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.
