Atypical Development Flashcards
In which developmental areas do most children progress through a series of milestones?
In their physical, social, communicative, and cognitive development.
What kind of of major individual difference exists among typically developing children?
Individual difference in the exact timing of the different milestones that each typically developing child attains.
What do some children exhibit, causing them to require additional support?
A markedly different developmental profile or delayed milestone attainment to typically developing children.
What have been developed to better understand and support children with developmental profiles that are different from those of typically developing children?
Clinical diagnostic systems
Which clinical diagnostic system is used in the US?
The Diagnostic and Statistical Manual
Which clinical diagnostic system is used globally?
The International Classification of Diseases
On what are diagnoses of developmental disorders usually based?
Clinical needs
What are designed in relation to clinical diagnostic systems, primarily to reflect particular clusters of difficulties that might need specific approaches to treatment?
Groupings
What are often identified and labelled by clinicians who observe constellations of unusual features that appear to form clusters?
Groupings of clinical needs.
What sometimes map onto specific aetiologies (causes)?
Unusual features that appear to form clusters (groupings of clinical needs).
What is Rett’s syndrome?
A rare genetic disorder resulting in severe disability.
How many females are affected by Rett’s syndrome?
One in 12,000.
Why is Rett’s syndrome rarely observed among the male population?
Because males with Rett’s syndrome do not tend to survive.
During which period of infancy does the development of children with Rett’s syndrome appear to remain relatively typical (despite often being subtly impaired)?
Between birth and (at least) six months.
During which period of infancy does the development of children with Rett’s syndrome begin to slow (stage one)?
Between the ages of six and 18 months.
