A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus. [1] The impact of context effects is considered to be part of top-down design. The concept is supported by the theoretical approach to perception known as constructive perception. Context effects can ...
The vertical–horizontal illusion. The vertical–horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. [1] This involves a bisecting component that causes the bisecting line to appear longer than the line that is bisected.
It has been shown that when an aftereffect and a simultaneous illusion of opposite biases were paired (first adapting to a clockwise oriented line and then presenting the vertical test line with a counterclockwise inducing line), the two effects summed linearly, [43] which also suggests a common mechanism of TAE and TI.
The Vertical-horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. Vista paradox: Visual tilt effects: Wagon-wheel effect: White's illusion: Wundt illusion: The two red vertical lines are both straight, but they may look as if they are bowed inwards to ...
The converging lines toward a vanishing point (the spokes) are cues that trick our brains into thinking we are moving forward—as we would in the real world, where the door frame (a pair of vertical lines) seems to bow out as we move through it—and we try to perceive what that world will look like in the next instant. [29]
the vertical–horizontal illusion. Another variant of the Wundt illusion is the Horizontal–Vertical Illusion, introduced by Wundt in 1858. The two intersecting lines are equal in length although the vertical line appears to be much longer. The horizontal line needs to be extended up to 30% to match the perceptual length of the vertical line.

A line's angle and its relationship to the frame's size influence the perspective of the image. Horizontal lines, commonly found in landscape photography, can give the impression of calm, tranquility, and space. An image filled with strong vertical lines tends to have the appearance of height and grandeur.
