What makes visual perception a hard problem

In the academic field, it is important to know which children may have trouble seeing the board or writing notes. In the medical area, knowing one's visual perception level will be important to know if the patient may misread instructions regarding their medication, or if they are unable to live and thrive independently.

Finally, visual perception in a professional environment will help when reading or working in a potentially dangerous situation. Knowing which workers should not be handling heavy equipment, or which may need assistance in a specific meeting may make a difference for an employer.

With the complete neuropsychological assessment , you can help to accurately measure a number of cognitive skills, including visual perception. This task makes it possible to understand how well the user is able to decode and decipher the different elements in the exercise, as well as measure the cognitive resources that the user has to understand and perform the task as efficiently as possible.

Aside from visual perception, the test also measures naming, response time, and processing speed. Like all of our cognitive abilities, visual perception can be trained and improved, and CogniFit may help train this ability. Visual perception rehabilitation is based on the science of neuroplasticity. CogniFit has a professional battery of tasks and tests that was designed to help professionals and individuals rehabilitate and improve deficits in visual perception and other cognitive functions.

The brain and neural connections, like a muscle, and be strengthened and improved through practice and training. This is why it's possible to actually improve one's visual perception by frequently training and exercising the correct neural connections. As visual perception improves, you'll have the possibility of sending information from the eyes to the brain quicker and more efficiently than before.

CogniFit was created by a team of professionals specialized in the area of neurogenesis and synaptic plasticity, which is how we were able to create a personalized cognitive stimulation program that would be tailored to the needs of each user.

This program starts with an evaluation to assess visual perception, auditory perception, and a number of other fundamental cognitive domains, and based on the results, creates a personalized brain training program for each user.

The program automatically collects the data from this initial cognitive assessment, and, with the use of sophisticated algorithms, creates a program that works on improving the user's cognitive weaknesses and training their cognitive strengths. The key to successful brain training is consistently practicing with challenging exercises. CogniFit has evaluation tools, as well as a rehabilitation program to help optimize this cognitive function.

The program only requires 15 minutes, two to three times a week. CogniFit's assessments and stimulation programs are available online and can be practiced on most computers and mobile devices. The program is made up of fun, interactive brain games, and at the end of each training session, the user automatically receives a detailed graph highlighting the user's cognitive progress. In a clinical setting, the CogniFit results when interpreted by a qualified healthcare provider , may be used as an in determining whether further cognitive evaluation is needed.

CogniFit does not offer any medical diagnosis or treatment of any medical disease or condition. CogniFit products may also be used for research purposes for any range of cognitive related assessments. If used for research purposes, all use of the product must be in compliance with appropriate human subjects' procedures as they exist within the researchers' institution and will be the researcher's obligation.

Symmetry vs. There is no need for processing interpretation as the information we receive about size, shape and distance etc. Gibson argued that perception is a bottom-up process, which means that sensory information is analyzed in one direction: from simple analysis of raw sensory data to ever increasing complexity of analysis through the visual system.

This optic array provides unambiguous information about the layout of objects in space. Light rays reflect off of surfaces and converge into the cornea of your eye. Because of movement and different intensities of light shining in different directions it is an ever changing source of sensory information.

Therefore, if you move, the structure of the optic array changes. According to Gibson, we have the mechanisms to interpret this unstable sensory input, meaning we experience a stable and meaningful view of the world.

Changes in the flow of the optic array contain important information about what type of movement is taking place. The flow of the optic array will either move from or towards a particular point. If the flow appears to be coming from the point, it means you are moving towards it.

If the optic array is moving towards the point you are moving away from it. They supply us with crucial information. Another invariant is the horizon-ratio relation.

The ratio above and below the horizon is constant for objects of the same size standing on the same ground. Are, in short, cues in the environment that aid perception.

Important cues in the environment include:. Gives the impression of surfaces receding into the distance. Objects with smaller images are seen as more distant. A large number of applications can be applied in terms of his theory e. His theory is reductionist as it seeks to explain perception solely in terms of the environment. There is strong evidence to show that the brain and long term memory can influence perception. Gibson's emphasis on DIRECT perception provides an explanation for the generally fast and accurate perception of the environment.

However, his theory cannot explain why perceptions are sometimes inaccurate, e. He claimed the illusions used in experimental work constituted extremely artificial perceptual situations unlikely to be encountered in the real world, however this dismissal cannot realistically be applied to all illusions.

For example, Gibson's theory cannot account for perceptual errors like the general tendency for people to overestimate vertical extents relative to horizontal ones. Neither can Gibson's theory explain naturally occurring illusions. For example if you stare for some time at a waterfall and then transfer your gaze to a stationary object, the object appears to move in the opposite direction.

Neither direct nor constructivist theories of perception seem capable of explaining all perception all of the time. Gibson's theory appears to be based on perceivers operating under ideal viewing conditions, where stimulus information is plentiful and is available for a suitable length of time.
