Identification and characteristics of students with communication disorders
Diagnosis of students with SLCN
standardized tests used for the diagnosis of SLCN
2. SPEECH & SPEECH DISORDER
SPEECH: The faculty or power of speaking, oral communication, ability
to express one’s thought and emotions by speech, sounds and gestures.
SPEECH DISORDERS: Speech impairment is characterised by
difficulties in articulation of words. Examples include stuttering or
problems producing particular sounds.
Articulation refers to the sounds, syllables and phonology produced by the
individual.
3. SPEECH & SPEECH DISORDER
Voice, however, may refer to the characteristic of the sounds produced
especially the pitch quality and intensity of sounds.
Apraxia of speech is: The acquired form motor speech disorder caused by
brain injury, stroke or dementia.
Developmental verbal dyspraxia refers specially to a motor speech disorder.
This is a Neurological Disorder.
Individual suffering from development verbal apraxia encounter difficulties
in sounds, syllables and words.
4. SPEECH & SPEECH DISORDER
The difficulties are not due to weakness of Muscles, but rather in-
coordination between the brain and the specific parts of the body.
Dysarthria is motor speech disorder that result from a Neurological injury.
Some stem from damage to CNS while other stem from peripheral Nerves
damage.
Orofacial myofunctional disorders to problem encountered when the tongue
thrusts forward in-appropriately during speech.
5. SPEECH & SPEECH DISORDER
Speech Sound Disorder may be of two varieties; Articulation or
phonological process
In articulation disorders may take the form of substitution, omission,
addition or distortion of normal speech sounds
Phonological process disorder may involve more systematic difficulties
with the production of particular types of sounds such as those made in
the back of the mouth like “k” and “g”
Stuttering is disruption in the fluency of individual’s speech.
6. Language & Language Disorders
Language is the ability to acquire and use complex systems of
communication.
Language Disorder is an impairment in the ability to understand and/or
use words in context.
Some characteristics of language disorders include improper use of word
and their meaning, inability to express ideas, in-appropriate grammatical
patterns, reduced vocabulary and inability to follow directions.
7. Language & Language Disorders
Specific Language Impairment(SLI) intervention for specific language
impairment will be based upon the individual difficulties in which the
impairment manifests for example if the child is incapable of separating
individual morphemes or units of sounds in speech then the intervention may
take form of rhyming.
Selective mutism is a disorder that manifests as a child does not speak in at
least one social settings. Despite being able to speak in other situation.
Aphasia refers to a family of language disorders that usually stem from injury,
lesion or atrophy to the left side of the brain that result in reception.
8. DIAGNOSIS OF LANGUAGE DISORDERS
The process of the speech-language assessment includes;
A primary caregiver interview
An examination of the child’s oral motor mechanism and functioning
Testing of receptive and expressive language
Evaluation of speech sound production, voice, and fluency.
It is important to include an audiological examination to determine the
status of the child’s hearing, preferably prior to a speech-language
assessment.
9. DIAGNOSIS OF LANGUAGE DISORDERS
The assessment includes the SLPs’ clinical observations of the
child’s interactions during the session with people, toys, and books.
In addition, the SLP will assess the child’s abilities through the use
of standardized tests and gather additional information with
informal checklists.
Standardized tests are designed to assist the examiner in
determining if the child lags behind children of his or her age in the
use of particular speech or language skills
