How well can you proofread?

Some programming-related decisions may not require an expert programming knowledge to make. We are experimenting to find out whether this is true in the context of reviewing (proofreading) programme code.

Are you a programmer?

With your programming expertise, you can help us understand how programmers think while reviewing code.

You will have to review a sample of source code to identify a set of specified defects while expressing your thoughts on the task, verbally, as they occur.

Are you not a programmer?

If you have no programming expertise, you can help us identify whether non-programmers can contribute to code review.

You will have to watch a few tutorials and complete a few tasks while expressing your thoughts on the tasks, verbally, as they occur.

The study will take 1 hour.

To be eligible you must be 18 years or above.

What's in it for you?
