Touch response for an IAT

sarah_econ · October 2018

I am trying to create an IAT about gender attitudes. I am not at all familiar with programming in Python and I was wondering if you could offer some tips.

Using the IAT template for windows , available here: https://osf.io/v8yaj/

I tried to create an android based IAT experiment with images but I am struggling with the response option. The experiment works with the keyboard response, but ideally, I would like to use a touch response as we will be conducting this experiment with tablets in the field. I played around with the options, but so far have failed to incorporate a touch response instead of a keyboard response (I think the inline script would require some additional lines?) Could you kindly give me some hints on what to add to the inline scripts?

Hi Sarah,

Looking at the experiment (IAT Template - with pool - english.osexp) all the responses are handled with keyboard_response items. So that's quite convenient, because it means that you can simply replace those with touch_response items.

Next, you'd need to change how the correct response is determined, which seems to be done in the set_correct_and_color item. If, in the touch_response, you define a grid with two columns and one row, the left side of the screen will be coded as 1 (instead of the e key), and the right side as 2 (instead of the i key).

Does that get you started?

Cheers!

Hi Sebastiaan,

I was able to make the corrections and all seems to work well. I will be taking my experiment to the field next month. Thank you very much for your help!
