Extract of sample "Schizophrenic Processing"

Download file to see previous pages As a result of their 1996 study, Silverstein, Matteson and Knight have concluded that the impairment results from a top-down impairment, specifically "in the ability to utilize contextual information" that acts as a "major factor in schizophrenia patients' perceptual organization difficulties." In their experiment, schizophrenic patients experienced the same level of confusion from a human voice imitating a sheep as that from what they thought was an actual sheep's voice, whereas the control group ceased having confusion once they learned that the voice was actually an animal, instead of a human. It is this lack of ability to adjust to reduction of ambiguity in context that is the basis of their findings.
Because these findings are similar in their relation to perseveration to other studies (Heaton, 1981; Lysaker & Bell, 1994), they do not represent a "leap of faith" nor require unconventional assumptions. Because these findings appear to more closely identify the source of the impairment as an "inability to utilize explicit contextual information" (Silverman et. al., 1996), however, they do add to the general understanding of impairments in top-down processing.
The key measurement in identifying the source of the impairment of top-down processing was the contrast betw...
The control group had a much easier time memorizing the group of numbers, once they knew that the sheep sound was not also made by a human voice, but was rather the product of an actual sheep. The schizophrenic group, however, did not improve in their ability to memorize the list of numbers, even after the authenticity of the sheep was made clear. The definitions of these groups within the testing population were made clear, as were the criteria for statistical and clinical significance. The definitions of terms, and of the handling of the experiment, are sufficiently clear to make the process easily duplicable.
The Silverman claim about top-down processing generates a significant need for further research. The authors note a need for aid in "determining if an auditory perceptual organization deficit is as specific to schizophrenia as its visual counterpart appears to be" (1996), as well as an analysis as to whether the perceptual organizational deficit is connected to one or more of the specific symptoms of schizophrenia. Because of this need for further research, the Silverman claim remains at the "descriptive" level of power. It does not speak toward influence of outcomes, or anything approaching prediction or control - however, it does permit discriminations in experience and identify specific relationships in top-down processing impairment. For their claim to be rejected, a control group would have to react to the identification of the stimulus' context in a much more similar fashion to the schizophrenia group than did the two groups in their study. If their claim is upheld by further research, however, the isolation of the source of top-down processing impairment could well be the first step towards ...Download file to see next pagesRead More

Processing Petroleum

...molecular makeup of crude oil varies from location to location as mentioned above however the chemical elements required to form crude oil vary over a fairly narrow margin. (Speight, 1999) The major hydrocarbon components of crude oil include paraffins, naphthenes, aromatics and asphaltics which display consistency in their presence in crude oil. The variation in these hydrocarbon components determines the exact properties of the crude oil in question. (Hyne, 2001) Crude oil contains a number of lighter more usable factions such as HFO, LFO, diesel, gasoline and a number of components for isomers of various kinds, asphalt etc. These factions can only be separated if crude oil is subjected to various processes.

Signal Processing Adaptive Filtering Introduction With the current technological advancements, digital signal processing remains amajor player with its application being found in noise filtering, voice prediction and system identification. An example if a signal processing system is the filter. Filtering refers to an operation in signal processing that processes a signal with the aim of manipulating the information it contains. Therefore, a filter maps an input signal to another output signal, thus extracting the desired information that the input signal contains.

Auditory Hallucination in Schizophrenic Illness

.... When the brain recognises that there is excessive dopamine, symptoms which are schizophrenic appear. Schizophrenic patients also have more dopamine receptors than people without it (Barkus et al., 2007). Glutamate is also associated with schizophrenia. It has a major role in the forming and encoding of memory. It is also thought to have a function in learning. When glutamate receptors are blocked for instance when one takes PCP, there is reported paranoia that is also a symptom of schizophrenia. Schizophrenic patients have been found to possess lower levels of glutamate compared to normal people. The two neurotransmitters interaction is said to be at the core of schizophrenia since...

Information Processing

...Information Processing 2007 Information processing Our sensory receptors are constantly under the influence of multiple signals, and though these can act independently from each other (e.g. sounds and smells), the human brain is able to combine them into images and scenes, therefore creating a whole picture of the surrounding world: Like energy, indeed, information has become ubiquitous as a commodity and, like energy, inescapable as an idea. The thesis that the human mind is nothing more than an information-processing device is now widely regarded as a fact. (Berlinski 2001, p. 17) The way human brain processes information about the outer world depends on different...
