Which visual phenomenon is associated with transient changes in visual perception?

The Troxler effect is associated with transient changes in visual perception because it illustrates how our visual system can adapt and respond to the constant elements in our visual field. When we fixate on a specific point, the peripheral stimuli can fade or disappear from awareness. This phenomenon happens because the neurons in the visual pathway that respond to those peripheral stimuli may reduce their firing rate over time when the stimulus remains constant, leading to temporary loss of perception of those stimuli.

This effect highlights the adaptability of our visual system, where prolonged exposure to a stimulus causes other surrounding visual information to become less noticeable, demonstrating how attention and visual perception can be influenced by fixation. The phenomenon indicates that our perception is not a static response to sensory inputs, but rather an adaptive process that can change based on context and lasting visual engagement.

Other visual phenomena, while also interesting, focus on different aspects of visual perception, such as color retention after a stimulus is removed (afterimages), the continuity of vision during rapid movements (persistence of vision), or the perception of motion that follows an actual movement (motion aftereffect). However, it is the Troxler effect that distinctly illustrates transient changes tied directly to sustained visual fixation and adaptation.
