IQ, or Intelligence Quotient, is a measure of a person's cognitive ability. It is typically measured with a standardized test, such as the Wechsler Adult Intelligence Scale (WAIS) or the Stanford-Binet IQ Test.
IQ is an important factor in assessing the severity of higher functioning autism. Individuals with higher functioning autism generally have IQ scores that fall within the normal range. However, their scores may be lower than average scores for their age group. This can indicate difficulties with cognitive functioning, such as problems with abstract thinking, problem solving, and reasoning.
Higher functioning individuals with autism may also display significant difficulty with social functioning. For example, they may have difficulty understanding social cues and interacting with others in appropriate ways. They may also find it difficult to sustain meaningful conversations.
In addition, individuals with higher functioning autism may have difficulty with executive functioning. This includes difficulty with planning, organizing, and completing tasks. They may also have difficulty with impulse control and self-monitoring.
Overall, IQ is an important factor in assessing the severity of higher functioning autism. Individuals with higher functioning autism typically have IQ scores that fall within the normal range, but may be lower than average scores for their age group. They may also have difficulty with cognitive functioning, social functioning, and executive functioning.
