The cognitive-development-child development generally refers to the whole of a child that develops from helpless to independent human beings. Besides the motor skills and the talent are taken into account to predict the act and to realize its intentions and its consequences, there are numerous studies that require the fascination of child cognitive development. These are based partly on a four-stage model. Thus, the cognitive development of a unit is the individual from the development stages of a child is discharged. The term is familiar with the age group 0-2 years as in the case of sensor motor stage; infants have their own knowledge through their bodies, their perceptions and their body movements. The preoperative level on the other hand refers to the period of life between 2-7 years, and is characterized by the force of the development of a mental process in which children sometimes have to judge their actions and the consequences. At the age of 7 to 11 years, children experience the concrete-operational stage where they can develop logical structures and actions targeted mainly used to achieve a goal. The formal operational stage is then between 11 and 15 years of age and is characterized by the fact that children cannot focus only on real events and things, but also make hypothetical issues and so can draw parallels or comparisons are not necessarily real need. All this refers to the cognitive development of a child, which is ultimately nothing more than that a little person learns to be drawn between the real world and the illusion created parallels, and so also to act responsibly and to recognize the results in advance. Therefore, all the issues related to human growth and development stages will be discussed in detail.
Importance of Life Course Stages
Disability is conceptualized within this volume as a social category that contributes to the exclusion of and prejudice against people with bodily or cognitive variations. This is in contrast to the conventional understanding of disability within much medical and therapeutic literature, which focuses instead on an individual impairment that result in inevitable exclusion. As such, this volume draws heavily on the social model of disability, as originally articulated by Michael Oliver in 1990. This model has been transformative in the lives of many people with disabilities, giving them both a shared identity as disabled as well as a political platform. There are a number of different factors that contribute to disability within a life course approach (Arnett, 2000, 480).
These factors can include age of onset of disability, which is considered to significantly impact an individual's life experience with disability; age at which disability is acquired, which affects long-term health outcomes; identity development; social interactions; and, gender identity, among others. In addition to age of onset, the degree to which the disability is lifelong and the extent to which its manifestations are cyclical can affect outcomes for people with disabilities over the life course. Disability is a condition that can come and go ...
