Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a ...
Perceptual learning is defined as a "change in perception as a product of experience, and has reviewed evidence demonstrating that discrimination between other words. that sound similar to their native language. They now can tell the difference whereas in category learning they are trying to separate the two.
Figure–ground (perception) Figure–ground organization is a type of perceptual grouping that is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a figure from the back ground. For example, black words on a printed paper are seen as the "figure", and the white sheet as the "background ...
Spatial ability is the capacity to understand, reason and remember the visual and spatial relations among objects or space. [ 1] There are four common types of spatial abilities which include spatial or visuo-spatial perception, spatial visualization, mental folding and mental rotation. [ 4] Each of these abilities have unique properties and ...
Figure 1 from The Block-Design tests by Kohs (1920) showing, in grayscale, an example of his block test. [1] A block design test is a subtest on many IQ test batteries used as part of assessment of human intelligence. It is thought to tap spatial visualization ability and motor skill. The test-taker uses hand movements to rearrange blocks that ...
Constructional apraxia. Constructional apraxia is a neurological disorder in which people are unable to perform tasks or movements even though they understand the task, are willing to complete it, and have the physical ability to perform the movements. [1] It is characterized by an inability or difficulty to build, assemble, or draw objects.
Visual neuroscience is a branch of neuroscience that focuses on the visual system of the human body, mainly located in the brain's visual cortex. The main goal of visual neuroscience is to understand how neural activity results in visual perception, as well as behaviors dependent on vision. In the past, visual neuroscience has focused primarily ...
Eye–hand coordination. Eye–hand coordination (also known as hand–eye coordination) is the coordinated motor control of eye movement with hand movement and the processing of visual input to guide reaching and grasping along with the use of proprioception of the hands to guide the eyes, a modality of multisensory integration.
