Every cell in the human body contains genetic material stored in genes that carry inherited traits which are grouped in structures called chromosomes.
The nucleus of each cell contains 23 pairs of chromosomes, half of which are inherited from each parent (www.ndss.org).
Down syndrome is caused when an embryo has threecopies of chromosome 21 instead of two. This supplemental chromosome 21 changes the embryo’s development and causes the characteristics associated with Down syndrome (www.ndss.org).
aggressiveness among the children with Down syndrome.
Methodprocedure We visited a school with children with special needs in order to observe their general behavior in the classroom environment. We had a brief discussion with one of their teachers to describe us the behavioral and emotional predispositions that children with Down-Syndrome display. We stayed there for about 2 hours observing 10 children carefully. We used the Likert scale where the behavioral patterns which we wanted to observe were written down to a list.
We went to another classroom to evaluate the behavioral patterns that children with Down syndrome displayed.
The independent variable of the proposed study was the teacher’s behavior and the dependent variable was the behavioral patterns of children with Down syndrome, their reactions and social interactions.
discussion Our hypothesis was not proven !! The children in our observational study seemed to interact with each other, be happy, calm and not display aggressiveness or any other problematic behavior. Nine out of the ten subjects had a moderate mental retardation so we cannot estimate or predict how children with higher mental retardation would behave. We conducted our study in a natural setting BUT we still do not know how these children would interact with or behave in their homes or in other settings apart from school.
The behavioral patterns and the degree of interaction that children with Down syndrome display are not due merely to their medical condition BUT also to the stimuli & warmth they get from their families and their environment !!

Thanks… Thank you ladies !!! And please …. Do to not forget to show support to people who really need it like the children with Down syndrome !!!
