Making new custom task for research

[tpjoe]

Hi,

We are looking to build a new active task to gauge participant’s cognitive functions. We are writing a proposal for the project, but having difficulties estimating how long it would take to develop such task. An example of the tests is provided here: https://www.youtube.com/watch?v=-6Ywml6l2kI

I realize this could depend on many factors, but could anyone weigh in on a ballpark estimate of how long such work normally take for a full-time developer?

Thanks!

Hi @tpjoe,

It looks like you the test is essentially an image recognition task. I have recently made something similar, which took me a couple of months, although I'm not a developer (I'm a researcher with some self-taught coding). The advantage was that I knew the task well, but the disadvantage was having to regularly look up solutions. You might be a developer, but if you are a researcher, I would be happy to help if I can.

From the look of it, your task has multiple (9) button options that can be matched to the displayed image. Have you considered how you would implement this many buttons on a phone? I guess you could fit multiple buttons in landscape, but portrait might be difficult.

Also, what results does the task produce? Typical of these tasks is percentage of correct matches and reaction time (for correct answers). What else?

Best wishes

Hi @davwillev, I'm not a developer either, but we plan to hire a contract developer if the proposal is funded. We wouldn't mind make it a portrait. And yes, we only want the % of correct matches and reaction time for the task. Do you have a guess of how long (rough ball park), it could take for a developer? Thanks!

The task itself should take no more than a month, absolute max, for an experienced developer. I reckon I could produce it faster than this myself. The app to deliver the task will probably take the most time. Drop me an email if you want to discuss options further :)
