Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes. Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not exist.
Psychologist E.R Jaensch states that eidetic memory as part of visual thinking has to do with eidetic images fading between the line of the after image and the memory image. [ citation needed ] A fine relationship may exist between the after image and the memory image, which causes visual thinkers from not seeing the eidetic image but rather ...
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.
To see a human-made picture such as an autostereogram where patterns are repeated horizontally, however, decoupling of focusing from convergence is crucial. [ 3 ] By focusing the lenses on a nearby autostereogram where patterns are repeated and by converging the eyeballs at a distant point behind the autostereogram image, one can trick the ...
The "psychic staring effect" has been reported in crowded classrooms and lectures. The psychic staring effect (sometimes called scopaesthesia) is the claimed extrasensory ability of a person to detect being stared at.
Satellite photograph of a mesa in the Cydonia region of Mars, often called the "Face on Mars" and cited as evidence of extraterrestrial habitation. Pareidolia (/ ˌ p ær ɪ ˈ d oʊ l i ə, ˌ p ɛər-/; [1] also US: / ˌ p ɛər aɪ-/) [2] is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one detects an object, pattern, or ...
Life review [a] is a phenomenon widely reported in near-death experiences in which people see their life history in an instantaneous and rapid manifestation of autobiographical memory. Life review is often described by those who have experienced it as "having their life flash before their eyes".
Those who can see their environments often do not readily perceive echoes from nearby objects, due to an echo suppression phenomenon brought on by the precedence effect. However, with training, sighted individuals with normal hearing can learn to avoid obstacles using only sound, showing that echolocation is a general human ability. [9]
