* Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason. Human intelligence is also thought to encompass our capacities to recognize patterns, plan, innovate, solve problems, make decisions, retain information, and use language to communicate
What is IQ?
An intelligence quotient (IQ) is a total score derived from a set of standardised tests or subtests designed to assess human intelligence.
The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligence Quotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book.
How to measure IQ for Autistic and Non Verbal Child?
Young autistic children are often nonverbal or have significant issues with processing language and responding verbally. Dr. Coplan notes that verbal responses may not be a good measure of IQ, nor a child's ability to manage interpersonal relationships, sensory input or motor skills. In fact, he says, "Nonverbal intelligence is the single biggest factor influencing the outcome."
Dr. Coplan recommends the comprehensive Test of Non-Verbal Intelligence (TONI), saying that children who do poorly on typical intelligence tests may do very well on the TONI. The test looks more directly at what children know than other tests—not at how well children can use language to communicate what they know.
In terms of the performance of full-scale IQ measures, the mean IQ level among children with ASD was 68.6 ± 18.1, ranging between 40 and 129.
According to the five cognitive profile groups considered in this study, more than half (61\%) of the children were found to have mild to moderate impairment in IQ level (IQ score <70), while 16\% were found to have average and above level of IQ (IQ = 90–129) and 14\% had a borderline impaired or delayed level of IQ (IQ = 70–79).
The distribution of IQ, as previously mentioned, was found to be positively skewed with a skewness of 0.745. This value of skewness indicates that the full-scale IQ measure was moderately skewed. The mean of nonverbal IQ was found to be 73.5 ± 17.5, while that of verbal IQ was 65.5 ± 17.6 .
The level of full-scale IQ varied with age, but the differences were not statistically significant. The IQ level showed a U-shaped pattern with age. Younger children below six years of age tended to have a higher average IQ score than their older counterparts. The nonverbal and verbal IQ also showed a similar pattern of distribution with age. However, the relation was found to be statistically significant in the case of verbal IQ .
Female children with ASD were found to have a slightly higher average IQ level (69.7 ± 18.5) than their male counterparts (68.3 ± 18.1). This is also true for verbal and nonverbal IQ levels. However, the male-female differences in IQ levels were found to be statistically insignificant .
