Survey2 | Ifpress

Thank you for agreeing to take this visual discrimination test survey.
On the next screen, you will be shown successive pairs of beer images that might vary -slightly- in the saturation (intensity) of the beer color.
For each pair, please indicate if you would consider that the beers look the same or if you would consider that they look different.
You will be shown a total of 20 pairs. Since this is a discrimination testing task, the differences, if they exist, will be quite slight.
When ready, please click "Next".
