What is direct perception?

Direct perception is a theory that claims that sensory perception is a direct result of information from the environment. This is contrary to indirect theories that people say that people use conclusions and beliefs to understand their sensory experiences. These topics are the subject of a living debate in some corners of the academic community, because they touch psychology and philosophy, where understanding how people perceive the world around them is the subject of great interest. A well -known scholarship in the field is James Gibson, who presented a strong argument for direct perception in the mid -20th century.

Sensory information comes from vision, hearing, touch, smell and taste, all of which provide information about the environment. Fans of direct perception believe that this is all the necessary information for understanding visual stimuli. This is a bottom -up approach where people create knowledge of the environment from what they perceive directly. In a tne -medical hypothesis, scientists say people use a combination of access from top and bottom -up, inThey use what they are experiencing, and conclusions from previous experience to collect information about their environment.

In the example of direct perception, a person standing in the library would have sensory feedback providing information about books, shelves and other furniture. A feeling of depth would be created phenomena such as superposition, where some shelves are in front of others. This could provide information about the depth and size of the library, as well as feedback, such as the size change. The vision of the observer would show a set of identical shelves that reduce. Rather than, provided that some are smaller and others are larger, the observer would know that some are further due to contextual information about them.

Critics direct perception that this view of perception is too simplistic and does not take into account the complexity of human perception. One of the topics of the discussion is the argument of the illusion that raises the point that people sometimesThey perceive things that are not there or incorrectly perceive sensory information. These perceptual tricks indicate that there is something more than easy feedback from the environment; For example, someone who sees pink elephants dancing in the Conga line in the middle of the forest does not actually see them. Obviously, it is a certain cognitive processing, which explains why the brain can be deceived by sensory stimuli that are not there or misleading sensory information.

It is difficult to test such a theory in a controlled way, because perception includes processes in the brain that are not easy to quantify. For example, using imaging studies, scientists can see which brain areas are activated when people are exposed to an incentive. However, they cannot see these brain areas when they become more active.
