three parts of language disorders
form, content, use
when the language disorder is NOT associated with a known biomedical etiology. (e.g., ASD, brain injury, DS, CP, hearing loss)
Developmental Language Disorder(DLD):
three models of language disorder analysis
categorical model, descriptive-developmental model, systems model
which model: Problem is an underlying disorder in the child, which prevents/impedes the child learning
categorical model
which model: Problem is a mismatch of child skill to the supports available in the environment
systems model
which model: Issue is child’s functional skill level, irrespective of etiology
developmental-descriptive
language is
Rule-based system of conventional symbols
speech is
Neuromuscular process of turning language into sound and perception of sound
communication is
process of information sharing
form is
How words, sentences, and sounds are arranged to convey content
use is
How people draw on language functionally to meet personal and social needs
content is
the meaning of language
three parts of form
phonology, morphology, syntax
one part of content
semantics
one part of use
pragmatics
phonology is
Rules governing the sounds that make syllables and words, and how those sounds are organized in words
morphology is
Rules governing the internal organization of words
syntax is
Rules of language governing the internal organization of sentences
semantics is
The rules of language governing the meaning of individual words and word combinations
pragmatics is
Rules governing language use for social purposes
perlocutionary - age and description
0-9 mo
infant not aware that behaviors (crying, smiling) affect partner
illocutionary - age and description
9-12 mo
Awareness that behaviors can affect partner emerges, but do not yet use words
locutionary - age and description
12+ mo
use of words
behaviors of typical bilingual language development (4)
- interference/transfer
- silent period
- code switching
- language loss/attrition
language transfer/interference
Sometimes characteristics of L1 can influence L2
It is important to consider: whether errors seen in English can be a result of the transfer
The greater the differences between the two languages, the more negative the effects of interferences are likely to be
silent period
The quiet period when a child is first exposed to a new language
During this time, the child: focused on listening and understanding
Can last from 3-6 months with significant individual variation
Generally, younger children tend to have longer silent periods
code switching
Changing languages within and across utterances
Code switching may be seen in new language learners as well as in fluent bilinguals
Example: A child says, “Quiero más cookies please.”
Language Loss
When ELL students are educated in mainstream English environments, they may receive much more input in English than their L1
Proficiency in L1 may be lost if it is not reinforced and maintained
