W5 - DLD Flashcards
What are the potential ‘risk factors’ for a language disorder?
- If a child has both receptive and expressive delay, difficulty is likely to be more persistent than if just an expressive delay.
- Family history of persistent SLCN
- Impaired performance on certain language tasks, for example recalling sentences
What is DLD?
Developmental Language Disorder is a language disorder that is not associated with an additional medical condition - there are no other identifiable causes for the child to present with a language disorder.
What are the characteristics of DLD?
- Different severity of difficulty in receptive v expessive language
- Any or all of the following areas may be affected: phonology, semantics, morphology, syntax and pragmatics
- Delayed vocabulary development
- Continued use of overextension or underextension past typical age
- Use of empty language
- Syntactic development is delayed - e.g. combining two words
- Difficulty with morphemes - e.g. -s suffix for plurals
- Attention/listening
- Difficulties with symbolic play
- Difficulties with visual perception tasks - e.g. shape discrimination
- Difficulties processing auditory information
- Neurological indicators such as clumsiness, motor difficulties or poor visual-motor coordination
- Less likely to initiate peer interaction
What impact can DLD potentially have on academic perfomance?
- Poor listening/concentration
- Difficulties reading and writing
- Poor overall academic performance
- Difficulty with organisation
- May not ask for help when needed
- May be seen as ‘naughty’ and get into trouble
What impact can DLD potentially have on relationships?
- Take things literally
- Not understanding jokes
- Interrupting and poor turn-taking skills
- Poor eye contact
- Shy
- Poor relationship formation ^
What impact can DLD potentially have on wellbeing?
- Shyness/withdrawn
- Low confidence and self-esteem
- Behavioural difficulties
- Avoid talking in class
What are the genetic factors in the aetiology of DLD?
- DLD tends to run in families
- Studies of identical and non-identical twins support a genetic link
- No specific gene has been identified that can be test to diagnose DLD
What are the neurological factors in the aetiology of DLD?
- Studies of brain structure and function have found there to be some differences that are potential risk factors for DLD
e. g:
* some children with DLD have an extra sulcus in the Broca’s area
What are the environmental factors in the aetiology of DLD?
- Important but not as significant in determining liklihood of DLD
- Some studies show the level of maternal education has an influence on DLD, but this is not a causal factor in other studies
What are the cognitive factors in the aetiology of DLD?
- Some researchers have identified linguistic and cognitive causes in DLD, such as cognitive processing impairment or verbal memory deficits
* there is debate as to whether these are causal or additional difficulties for children with DLD
