Lorenzo Colbert Jr. Introduction The topic that the journal is on is visual perception . Visual perception the ability to see the surrounding environment as it is in the visible spectrum by the things in the environment. To a certain degree what we perceive is inf luenced by what we know. Although a large amount of research and documented citings claim to be. Some show effects of knowledge, expectations, and o ther cognitive states on many aspects of perception, strong cou nterarguments have been developed that these demonstrations are confounded by non - perceptual factors. For example, although letters are easier to recognize in meaningful words than meaningless letter strings, skepticism remains that such effects of knowledge on visual recognition mean that knowledge literally helps people see. Topic Of Interest The process to comprehend in one's habitat is referred to as percepti on. If perception is imprecise or changedin any way prob lems simple day to day skills may occur.Visual perceptual skills involve the ability to organize and interpret the information that is seen and give it meaning. The importance of visual perceptual skills in academic success is agreed upon by many, acknowledging reading would not be possible without adequate visual perception. Without correct visual interpretation, a student may experience difficulty learning in the class room, visualize items or past experiences, have good motor skills , integrate visual information with other sens es to do things like play catch, shoot baskets when playing basketball, or hear a sound and visualize where it is coming from like the horn on a truck . Current Research H aving some type of prior knowledge about what you are looking at may or may not help you see it. This article pres ents several experiments showing that i t does. The different studies show that people are m uch better able to detect acute changes to meaningful words than to meaningless letters or to even less meaningful words. These findings reinforce the idea that what we see depends not just on what we are looking at, but also on what we know and expect. In Experiment 1, a perceptual matching task is used to show that meaningful words appear more distinct than meaningless letter strings. In Expe riments 2 through 4, it is demonstrated that humans are more accurate in d etecting acute changes in indistinct shape when they occur in meaningful words compared with meaningless letter strings. In Experiment 5, it is shown that this development in perfor mance cannot be explained only by d ifferences in visual intimacy , but is predicted by semantic factors such as word imageability . These findings solidly the fact that visual perception isn't always about what you see just more so of what you know. The words we already know can be distorted greatly and our brain would still be able to identify each word with some ease. Conclusion Altogether the results show that meanin gful letter strings look more acute than unfamiliar ones, and that word comprehension improves exactness in seeing simple perceptual changes happening right be fore a person's eyes. Visual Perception is not encased from knowledge, but enriched by it.
