    One of the explanations for the Ponzo illusion is the "perspective hypothesis", which says that the perspective feature in the figure is produced by the converging lines ordinarily associated with distance; the two oblique lines appear to converge toward the horizon or a vanishing point. We interpret the upper line as though it were further ...

    The head-up illusion involves a sudden forward linear acceleration during level flight where the pilot perceives the illusion that the nose of the aircraft is pitching up.

    Similarly, S′ is the perceived linear extent by which the subjective point A′ appears directly above point B′. The observer could simply say how many inches or meters that vertical distance looks. For a viewed object, S′ thus is its perceived linear size in meters, (or apparent linear size).

    These hints include relative height, relative size, linear perspective, lights and shadows, and relative motion. [15] Each hint helps to establish small facts about a scene that work together to form a perception of depth. Binocular cues and monocular cues are used constantly and subconsciously to sense depth.

    Obviously, this increases the dynamic range of a neuronal population, while stimulus-derived changes remain small and linear proportional. An analysis [ 26 ] of the length of comments in internet discussion boards across several languages shows that comment lengths obey the lognormal distribution with great precision.
