Weegy: Sensory integration occurs at all levels of the central nervous system. However, the brain stem (including the midbrain, pons, and medulla oblongata) appears to play the most significant role in sensory processing. [ The brain stem and the thalamus receive sensory information from every sensory modality. Information passing through these structures is modified, integrated with other sensory information, and directed to the brain's cortex. As multiple sensory information impinges upon the brain, a finely tuned filter system comes into play. Sensory input pertinent to the individual's inner needs and goals reaches a level of consciousness. Input which is less important or distracting is dampened down centrally. The reticular formation in the brain stem (which plays the central role in this filter system) is often considered the master control mechanism of the central nervous system. It helps the brain to focus on one type of sensory input by inhibiting other types of input. This allows the individual to focus attention, and reduces the level of distraction. ............ ] User: b Weegy: How can I help you? (More)

Weegy: Reaction to a diagnosis of autism varies very much from family to family. Nissenbaum, Tollefson and Reese (2002) studied the impact of diagnosis on families and professionals. [ [ Parents felt relief to be a benefit of having a diagnosis: they no longer feel that the problems they face are due to their lack of parenting skills and they have an explanation for themselves and others as to why their child exhibits unusual behaviours. Parents may also react by crying; feel surprise, devastation or helplessness; and by wanting additional information about autism. However, it is acknowledged that the information they receive is not enough. The National Initiative for Autism: Screening and Assessment (NIASA) report (2003) stresses the need to provide more information and to involve families throughout the assessment process. For example, local parent groups, education and training for parents, carers and professionals and information about support services are important. Some parents in the Nissenbaum, Tollefson and Reese (2002) study did not believe the diagnosis and some even became angry or questioned the professional's ability. Many were worried as to how other close relatives and friends would react to the diagnosis. Suspecting autism decreased the likelihood of shock. Many parents and professionals said family members went through a grieving process after hearing the diagnosis. Regardless of their reaction, families did not feel that a diagnosis of autism influenced their interactions with their child. Gray (2003) found that mothers, in particular, experienced considerable guilt and depression about their child's disability. The diagnosis also meant they experienced a number of additional domestic tasks - such as treatment issues and problems surrounding education - as a result of their child's autism. ] ] User: how do families needs change for families with asd (More)
