Visual Same-Different Task

​

Instructions

• 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".
