discussion</li></li></ul><li>IntroductionWhat is Down Syndrome?<br /><ul><li>It is a set of mental and physical symptoms that result from having an extra copy of chromosome 21</li></ul> in other words…<br /><ul><li> A set of physical, mental and behavioral characteristics that are due to a specific genetic abnormality (Leshin, 2003).</li></li></ul><li>Introduction historical background of Down-Syndrome<br /><ul><li> In 1866 John Langdon Down described a group of children with common traits that differed from other children with mental retardation.
In the beginning, children with Down syndrome were referred as “mongoloids” because they looked like people from Mongolia but, the term was changed to Down’s syndrome.</li></li></ul><li>Introductionhistorical background…some photos…<br />
Introduction An overview<br /><ul><li>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).</li></li></ul><li>Introduction causes<br /><ul><li>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).</li></li></ul><li>Introduction Associated Features<br /><ul><li>Flattened face & nose
Thyroid conditions</li></li></ul><li>Introduction Associated Features (cont.)<br /><ul><li>Cognitive delays and difficulties in:</li></ul> developing basic language skills & motor skills &<br /> learning abilities (such as memory & concentration problems ).<br /><ul><li>Difficulty in:</li></ul> solving problems &<br /> the comprehension of consequences of their actions (Iarocci, Reebye & Virji-Babul, 2006).<br />
Introduction previous literature<br /> Children with Down syndrome:<br /><ul><li>Experience limited peer involvement & have difficulties in socializing with their peers.
Have fewer peer contacts and engage in very few activities with other children.
Have the tendency to exhibit problematic behaviors such as stubbornness, inattention, difficulties concentrating, attention-seeking, and impulsivity (Guralnick, 2002). </li></li></ul><li>IntroductionHypothesis<br /><ul><li>Children with Down syndrome have difficulties in interacting with each other and display abnormal behavior and significant impairment when disturbed.</li></li></ul><li>method<br /><ul><li>Participants:
Ten children (aged 7-18 years old) with Down syndrome.
Five boys & five girls of greek nationality from different socio-economical backgrounds.
aggressiveness among the children with Down syndrome.</li></li></ul><li>Methodprocedure<br />We visited a school with children with special needs in order to observe their general behavior in the classroom environment.<br /> We had a brief discussion with one of their teachers to describe us the behavioral and emotional predispositions that children with Down-Syndrome display.<br /> We stayed there for about 2 hours observing 10 children carefully.<br />We used the Likert scale where the behavioral patterns which we wanted to observe were written down to a list. <br />
Methodprocedure (cont.)<br /><ul><li>The first 30 minutes their teacher read them a story & asked to describe him their emotions or thoughts about this story
Afterwards the children did a couple of activities such as :
We went to another classroom to evaluate the behavioral patterns that children with Down syndrome displayed.</li></li></ul><li>Methodresearch design<br /><ul><li>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. </li></li></ul><li>results<br /><ul><li>Children were quiet & shy
After their teacher read them a story & asked from them to express their emotions about it, 8 out of the 10 subjects used facial expressions and body language to show their feelings. </li></li></ul><li>Results (cont.)<br /><ul><li>When their teacher tried to examine their reactions (how they react if someone disturbs them), we found out that if someone tries to take away their personal things or speak to them aggressively:
show their anxiety with facial expressions associated with anger
tremble a bit</li></li></ul><li>Results (cont.)<br /><ul><li>But... if afterwards you show affection and hug them (like their teacher did), they calm down very easily. </li></li></ul><li>Results (cont.)<br />
discussion<br />Our hypothesis was not proven !!<br />The children in our observational study seemed to interact with each other, be happy, calm and not display aggressiveness or any other problematic behavior.<br /> 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.<br />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. <br />
with various degrees of mental retardation </li></li></ul><li>conclusion<br /><ul><li>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 !! </li></li></ul><li>Some additional photos…<br />
Thanks…<br />Thank you ladies !!! <br /> And please ….<br /> Do to not forget to show support to people who really need it like the children with Down syndrome !!!<br />
