We study the use of crowdsourcing for self-reported attention in image quality assessment (IQA) tasks. We present the results from two crowdsourcing campaigns: one where participants in- dicated via mouse clicks the image locations that influenced their rating of quality, and another where participants chose lo- cations they looked at in a free-viewing setting. The results are compared to in-lab eye tracking experiments. Our analysis shows a strong connection between the in-lab and self-reported IQA locations. This suggests that crowdsourced studies are an affordable and valid alternative to eye tracking for IQA tasks.
