The neuropsychological side of visual information processing is known as visual perception, an abnormality of which is called visual impairment, and a complete absence of which is called blindness. The visual system also has several non-image forming visual functions, independent of visual perception, including the pupillary light reflex and ...
Sense of direction is the ability to know one's location and perform wayfinding. [1] [2] It is related to cognitive maps, spatial awareness, and spatial cognition. [3] Sense of direction can be impaired by brain damage, such as in the case of topographical disorientation. Humans create spatial maps whenever they go somewhere.
One proposes that crossing generally provides better geometrical mapping. [12] According to another view, the crossing is a coincidence that has been conserved by parcellation. [ 8 ] A third hypothesis proposes that the crossing results directly from optical inversion on the retina of the eye.
Depth perception can be enhanced by having eyes which are enlarged in one direction; distorting the eye slightly allows the distance to the object to be estimated with a high degree of accuracy. [8] Acuity is higher among male organisms that mate in mid-air, as they need to be able to spot and assess potential mates against a very large backdrop.
The ability of a subject to detect coherent motion is commonly tested using motion coherence discrimination tasks. For these tasks, dynamic random-dot patterns (also called random dot kinematograms) are used that consist in 'signal' dots moving in one direction and 'noise' dots moving in random directions. The sensitivity to motion coherence is ...
When looking at individual differences, it appears that most people have a preference for one reference frame with a different use of strategies to represent space. Some people have an inclination towards a route view (also called route strategy), while others have a preference towards a survey view (also called survey or orientation strategy ...
Earth’s inner core, a red-hot ball of iron 1,800 miles below our feet, stopped spinning recently, and it may now be reversing directions, according to an analysis of seismic activity.
A stance with the left foot forward is called "regular" or "normal" stance. Jump and spin Direction of rotation in figure skating jumps and spins is not necessarily the same as the footedness or the handedness of each person. A skater can jump and spin counter-clockwise (the most common direction), yet be left-footed and left-handed. Ocular ...
