Depressed people may see the world differently—literally. Here's why, writes ArashEmamzadeh
Below, I discuss the study further, beginning with a description of brightness induction and contrast suppression. Refer to Figure 1 as you read the sections below .refers to how center brightness is affected by surrounding luminance. See the top visual illusions in Figure 1: The center patches are the same in A and B, yet the one in A appears dimmer and the one in B appears brighter. This occurs because of the effects of the surrounding brightness.
To test brightness induction in controls and clinically depressed patients, experimenters presented the participants with two center squares surrounded by backgrounds of higher or lower luminance; participants were instructed to select the brighter of the patches. For each image, the center and the background had either a small or large difference in luminance., which refers to the effects of the surrounding on the apparent contrast of the visual pattern in the center.
This optical illusion occurs because the lines in the center square C and its surrounding are collinear . The lines in D and its background are orthogonal . To test contrast suppression, experimenters presented two images to participants, who were asked to select the pattern with the greater contrast. The patches in these images had high-contrast backgrounds that were collinear or orthogonal. The contrast of the image itself was low. Note: Some patches were presented with no surrounding images.Before looking at the results, let us learn more about the study’s methods and those who participated in the above experiments.
