OSEL Can Diagnose (Nonverbal Communication) Autism


As autism or ASD (Autism Spectrum Disorders) takes the first place among all brain diseases and mental disorders due to its incurable symptoms of social skill impairment so, we need to be more conscious to reveal the unrevealed things of autistic disorders.

And for this thing we need to continue our study and research. The first thing to study autism is identifying the people with autistic disorder through proper diagnosis. Diagnosis on or before the age of 3 is very helpful to start the treatment and for increasing the chance of recovery though autism is incurable because of its strong genetic basis.


Diagnostic Parameters:

So to identify autistic children as early as possible, we use some basic and fundamental diagnostic parameters like,

  • Lack of verbal communication
  • Lack of eye contact
  • Repetitive behavior
  • Cognitive disabilities


Lack Of Verbal Communication:

So, the first point comes with the point of non-verbal communication to diagnose a child with autistic disabilities. The symptom of communication problem becomes a hall mark of autism but non-verbal communication is found in a quarter of people autism. Others with autistic disabilities speak with fluency though some of them speak with abnormal patterns like echolalia. Echolalia is one kind of verbal abnormality with repetition of words or vocalization, heard from another source or person.

So, the test of verbal communication may not be enough to identify children with autistic disorder because some autistic children with the fluency of speak may be skipped or ignored from the treatment.


Study On OSEL:

That’s the reason why researchers have designed a test, named OSEL (Observation of Spontaneous Expressive Language).

A study was conducted to see whether this technique is O.K or not to diagnose the autistic children with the basis of verbal communication. The test was done taking 180 typically developed children in Michigan and those children were in the range of 2 to 5 years old. The test was very easy and skillful. The task was done including two performance at a time. The participants played with toys with talking to the examiner simultaneously. It was observed whether the pattern of their words was idiosyncratic with wrong or different prepositions and adjectives including various tenses and verbs. Their behaviors were also noticed whether the conversion was dominating or interrupting the examiner to engage more with play.


Observation & Conclusion:

According to the study it was also observed that the girls with autism are more masked than boys as most of girls show the advanced language skills than boys of same age.

The study shows that this gap of language skills between male and female child decreases with the age. So autism with verbal expression needs more study to reveal such things.
