jsPsych code for executive functioning battery

To-Do:

1. Combine the three tasks (Spatial Recall, Go/No-Go, Hearts and Flowers), ideally using the latest version of jsPsych; present them to the subject in the following order:
   1. Spatial Recall
   2. Go/No-Go
   3. Hearts and Flowers
2. Extract variables from URL, and save to exported data:
   • subject ID: subid
   • SONA ID: sonaid
3. Export data from each task, separately, as csv, with filename as: task_subid.csv
4. End Spatial Recall task when get two wrong in a row
5. Have each task run in fullscreen mode (like the Go/No-Go task)
6. On finish, redirect to external URL, but only if sonaid != 0

• Maybe:
  • Combined Progress Bar
    • but, can do this later in post-processing (so don't lose raw data)

Instructions:

• Place code in this github repo
• Comment code clearly, and commit each change separately so I can see and learn how to do each step, e.g.:
  • combine tasks
  • extract subid and sonaid from URL
  • export data from each task, separately, as csv, with filename as: task_subid.csv
    • export data from all trials:
      • for Hearts and Flowers task, include at least the following:
        • condition: congruent (heart_practice_trials), incongruent (flower_practice_trials), mixed (trials)
        • trialType: heart, flower
        • switchTrial (whether it was a switch trial): 1 (yes), 0 (no)
        • accuracy: 1 (correct), 0 (incorrect)
        • reaction time: time (in milliseconds); -1 if no response
        • fullScreen (whether the screen was in fullscreen mode the whole time): 1 (yes), 0 (no)
  • end spatial recall task when get two wrong in a row
  • have each task run in fullscreen mode
  • on finish, redirect to external URL, but only if sonaid != 0
• Use these lines to extract the subject ID and SONA ID from the URL, so they can be saved in the filename and datafile, and can be used to assign credit.
  • var subid = jsPsych.data.getURLVariable("subid")
  • var sonaid = jsPsych.data.getURLVariable("sonaid")
• At the end of the final task, with the on_finish function, include the code to redirect SONA participants to an external URL, but only if their sonaid != 0.
• To save the data on the server, use the write_data_new.php PHP file
• Use/adapt this the code to save the data:

Redirect to URL

This is code to redirect participants to an external URL. Use/adapt this code to redirect participants to a URL, but only if their sonaid != 0. We need to replace the https text before +subid with my SONA project completion URL and remove the XXXX and put subid. I will supply a revised experiment_id and credit_token (the ones in the link above are for another study)

on_finish: function(){
                window.location = https://uiowa-psych.sona-systems.com/webstudy_credit.aspx?experiment_id=476&credit_token=78a4b09dd29b421cb92b7ffa6db933d8&survey_code=+subid }

Save Data

This is code to export data. Use/adapt this the code to export data from each task, separately, as csv, with filename as: task_subid.csv I'm not sure what the "filter" is for, and we are using a different task.

    /* save the data */
    var save_data_block = {
        type: 'call-function',
        func: function(){
            console.log(jsPsych.data.get().filter({trial_type: 'arrow-stim'}).csv())//this should work
            data = jsPsych.data.get().filter({trial_type: 'arrow-stim'}).json()
            save_data(data,'arrow-data',ExpName,subid)
        },
    }

Post-Processing

Spatial Recall

Go/No-Go

• set anticipatory responses (RT < 200 ms) to missing for both accuracy and RT
• examine RT in correct go trials only

Hearts and Flowers

• set anticipatory responses (RT < 200 ms) to missing for both accuracy and RT
• examine RT in correct trials only
