Quizplus · Accepted Answer

The effect described in the passage is known as the pop-out effect, where a single stimulus (in this case, a vertical line among slanted lines) stands out and is quickly and easily detected. This effect is well established in visual perception research and has been demonstrated in infants as young as three months old. The other options (somesthetic, gate-control, stereoscopic) do not accurately describe the effect being discussed.
