In gradation Processing - Essay ExampleThe way human brain processes discipline about the outer world depends on different factors and, above all, upon the context. For instance, if a person looks at some complicated picture, e.g. a portrait, it is enough to cast one glance at what is depicted on it, whereas comprehending the corresponding picture would hardly be possible if this person begins analysing different exposits of this portrait separately, one by one. This peculiarity of schooling touch on is due to the fact that the brain operates the sensory signals that are perceived together, not separately. (Schweizer 1998, p. 89)The visual signals normally reach our eyes simultaneously and therefore in case with visual images the processing of information begins from the retina. The breaks that constitute speech reach the arresting organs successively, and that is why for processing a sound image it should first be stored in short-term memory. For the identification of the al ready known images, the brain compares the information recorded in the short-time memory with the classes of images contained in the long-term memory that contain the information about the precedent bed that has been collected in the process of studying and communicating.One of the challenging aspects of processing information is recognition of stimulus in the situations where there are a lot of similar symbols - e.g. when someone is talking to other person in a noisy room. In such situations, though the stream of sounds produced by the jobber is accompanied by other sounds, it is normally possible to comprehend the speech. Quite a simple type where the context of information creates the context is the illusions of sound continuation or phonetic restoration. A brilliant type of this phenomenon was described by Richard Warren if you hear some phrase whose meaning you cannot catch, but you definitely hear its ending - ... eel is on theNow, if you put the give-and-take orange a t the end of this phrase, you will hear peel is on the orange if the word is wagon, the phrase will sound as wheel is on the wagon if it is shoe you will perceive the phrase as heel is on the shoe. (Warren 1970) This experiment shows that the sound stimulus in itself (noise + eel) fails to determine unambiguously what will be heard by the recipient.AttentionAttention is the process of sorting the information that comes from outside in accordance with the importance of the tasks a person has. There are several kinds of attention active (voluntary) attention that is conditioned by a certain conscious goal, and automatic (involuntary) attention that is actualized under the influence of unexpected and new stimuli in the form of orientating reflex. (Lachman & Lachman 1979, pp. 183 - 185)The effectiveness of attention can be determined by its level (concentration and intensity of attention), volume, rush along of switching to other objects, and stability. It has been proved that the atte ntion processes are connected with functioning of the corpus collosum, the left part of the brain ensuring selective attention and the right part - maintaining the general level of awareness.MemoryMemory is a very important phenomenon that is crucial for our lives. Thanks to it, we are able to use our own experience and the experience of other people in our lives. There is short-term and long-term memory. Short-term memory is also called intelligence officer memory. To illustrate the
