The external human body consists of a head, hair, neck, torso (which includes the thorax and abdomen), genitals, arms, hands, legs, and feet.
The perception of facial features is an important part of social cognition. [2] Information gathered from the face helps people understand each other's identity, what they are thinking and feeling, anticipate their actions, recognize their emotions, build connections, and communicate through body language. Developing facial recognition is a ...
The Homonculus is a visual representation of the intensity of sensations derived from different parts of the body. Wilder Penfield and his colleague Herbert Jasper developed the Montreal procedure using an electrode to stimulate different parts of the brain to determine which parts were the cause of the epilepsy. This part could then be ...
The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina), with the brain altering the basic information taken in. Thus people interested in perception have long struggled to explain what visual processing does to create what is actually seen.
Different species are able to see different parts of the light spectrum; for example, bees can see into the ultraviolet, [55] while pit vipers can accurately target prey with their pit organs, which are sensitive to infrared radiation. [56] The mantis shrimp possesses arguably the most complex visual system of any species. The eye of the mantis ...
For example, if part of a shape's border is missing people still tend to see the shape as completely enclosed by the border and ignore the gaps. Good Continuation: the principle of good continuation makes sense of stimuli that overlap: when there is an intersection between two or more objects, people tend to perceive each as a single ...
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or sensory functions, for different parts of the body.
Such body language may be established gradually over a period of courtship. The body language of intimate relationships cannot be used acceptably in non-intimate relationships. [56] When people are in an intimate relationship, they often position themselves closer to each other than if they were in a different kind of relationship.
