How to access the data from all trials that meet a given criteria?

[viviers]

I need to access all previous trials where:

key_press = 'a' AND effort_level = 75

Then I need to create an array of their data for a variable called reward_offered (this variable takes integers)

So the array of all reward_offered might look like this:

array = [12, 14, 6, 9, 12];

Once you access the data with jsPsych.data.get() there are a variety of operations that can be used for filtering, extracting, summarizing, etc.

This is how you filter. Note that key_press: 65 because the key code for a is 65.

var filtered_data = jsPsych.data.get().filter({key_press: 65, effort_level: 75})

Then you can extract reward_offered as an array (assuming that it is in the data for that trial):

var array = filtered_data.select('reward_offered').values;

Thanks so much!
