Download file to see previous pages ASD, Autism spectrum disorders are enduring neurodevelopmental disorders described as impairments in these three areas of functioning: communication abilities; restricted, stereotyped or repetitive behaviour patterns; and social behavior. Most researchers concur that autism is originated by either abnormal organization within the central nervous system, irregular brain structure, or both. Due to the variation of symptoms, the wide variety in their severity and the functional deficits’ continuum, the term ASDs is now being utilized to report the disparity observed in these children (Wing, 1997). Although there had been several theoretical evidence regarding the causes of autism, nowadays, more specific knowledge is available for the neurological and genetic abnormalities that exist.
It’s been proposed that a surplus of axons in particular regions of brain results in an over-connection of these regions. Yet, their connections to other regions of the brain seem to be fragile (Herbert, 2005). It seems to be a need of coordination among these areas of brain. This lack of synchronization seems to affect brain functioning. People with ASDs have trouble conveying dissimilar cognitive functions mutually in an organized way. They suffer from difficulties in organization and planning (Prior & Hoffman, 1990). Synchronizing volition with sensation and movement can be complicated for some. In autism every part of the brain appears to perform on its own (Just et al., 2004) thus lacking a coordination of information.
The information related to the environment is interpreted through sensory systems. It can be explained as a process within the brain which arranges sensory experiences – sound (taste), touch, gravitational pull, body awareness, movement and sight – into collective information which is then utilized by the individuals in reacting to and learning about ...Download file to see next pagesRead More

Sensory Discrimination

...of the observed results we get the p-value for the test.The exclamation mark denotes factorial function and thusindicates successive multiplication by cardinal numbers in descending series. For example, 4! means 4 x 3 x 2 x 1. (Siegel, 1988) Conclusion Since the exact conditional probability of sensory discrimination where p = 0.1312 which is greater than 0.05, then by the decision rule we accept the null hypothesis that the subject has no sensory discrimination. The use of random samples and avoiding of using united data confirms the validity of the Fisher Exact test, and the data produced through interaction with the respondent provides a...

Sensory Integration Assessment

...abilities but still require practice to assimilate the two areas. If not, it may show visual and /or motor deficiency. Short Sensory Profile: The Short Sensory Profile Test determines the “sensory modulation disorders” (Bundy, Lane, & Murray, 2002, p. 8). Sensory processing is the major field which is usually used for evaluation because it represents the core concept compared to just modulations. The deficiency in sensory modulations is assessed from the responses of the object to a sensory stimulus demonstrating deviations from normal. The Short Sensory Profile Test...

Sensory Perception

.... Sensory information can further be made accurate or inaccurate based on confounding of different sensory organs and the data perceived. One sensory organ can pick information correctly, while another can take in information from a different angle making the information conflicting and interpretation becomes difficult. This also makes sensory information processed inaccurate by not following dynamics of the environment and the input of all the senses (Hwang, 2008). Besides the different factors mentioned in influencing the accuracy of sensory information, analysis and assessment of sensory data, nature and nurture are...

Sensory Evaluation

...Sensory Evaluation Analytical sensory tests are the sensory evaluation methods that require analysis in getting information regarding a s reaction to differences between samples. Among the analytical type of tests are the single sample, two sample or paired, triangle, duo-trio and the multi-sample scoring and scaling. These methods are the bases upon which other approaches and variations are developed. Each test has its own specific uses and limitations. The extent of their usefulness may be determined mainly by the type of information desired, the number of test samples and the available time, effort and money. (Gatchalian , 1975) Difference - The easiest to conduct and analyze. The method involves the presentation of a set... for one...

Sensory analysis

...(Questionnaires), and the Home use tests (HUT). The products sensory attributes are analysed using procedural descriptive Analysis Method. It consists of a complete, detailed and accurate descriptive characterization. This provides information on the perceived sensory attributes (characters or notes) and the levels or intensities of each of the characters. For the purpose of drawing comparisons within a product group the perceived intensities are recorded in relation to absolute or universal scales. The relative intensities among attributes within a product group and among other products tested give an indication of the way the target consumer groups...

The Sensory Nervous System

...Perception of stimulus- Role of Central and Peripheral nervous systems The increased complexity of the human body, brought about by evolution, alsoincreased the need for co-ordination and control of the various parts of the body. This is brought about by the nervous system. There are two distinct sections of the human nervous system, the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system comprises of the brain and the spinal cord, whereas the peripheral nervous system includes the spinal nerves and cranial nerves. The PNS essentially acts as a channel to relay...

...shape to be able to function properly. 3. Discuss the roles of "nature" and "nurture" with regard to the interpretation and evaluation of sensory data. Nature and nurture have always affected the existence of beings (Myers, 2009). These two forces also have significance in the assessment of sensory data. The human body’s development is affected by the elements around it like time, temperature, and food. Inherited traits such as physical attributes, allergies, and diseases are likewise essential in determining one’s existence. Considered under nature are some atypical conditions of the nervous system that are not proven to be inherited like different kinds of syndromes and...

Sensory Perceptions

...a product of human sensory capabilities. In other words, our capacity for knowledge is limited by the range and depth of our sense faculties in receiving and interpreting data. Thus, understanding the roles of nature and nurture are essential to the epistemological analysis. To the extent that human beings are a product of a long line of evolutionary adaptation, our DNA and the basic imperatives for the survival of our genes (the building blocks of DNA) dictate and define meaning. Hence, from the point of view of our species, knowledge has an evolutionary role, namely that of survival. Perhaps our sensory perceptions can only reach thus far and may never fetch the ‘absolute truth’,...

Sensory Perceptions

...Sensory Perceptions" Introduction Perception is an individual understanding and decision. Depending upon the knowledge, insight and thoughts, an individual judges and understands the situation. Since, knowledge and experience decides the quality of pronouncements and influences life of an individual to a greater extent, individual must make a decision with presence of mind. The final decision depends upon the sensory perception, judgment of the situation and prior experiences. Every individual is an inseparable part of the society, therefore, in certain cases some decisions also persuade the society. Knowledge alone cannot provide the wisdom and thoughtfulness to take the right decision but experience...

...information using structures that are already built in their human system. This means a person’s genetic makeup has an influence on the correctness of his sensory perception. Nonetheless, it is not a must for these in-built structures assist people to make precise account about the nature of a person, event or anything. In addition, people’s natural behaviors help them survive more than it helps them formulate accurate judgments or statements. On the other hand, nurture or external factors, also affect the sensory data’s accuracy (Foster, 2000). Factors such as school, work or family, determine how a person decodes and appraises sensory information. References Armstrong,...
