What retinal location was tested in the experiment?

Explanation:
Testing at 20 degrees from the center means the stimuli were presented in the peripheral retina, not at the fovea. The fovea (near 0 degrees) gives the highest spatial resolution, while at 20 degrees the receptive fields are larger and acuity is lower, leading to different sensitivity and performance patterns. This mid-peripheral location is commonly used to study how perception changes with eccentricity, so the experiment’s results specifically reflect processing in that region of the retina.
