High Functioning Autism (HFA)
People with high-functioning autism usually have an average or above-average IQ. Although they typically have adequate vocabulary, their comprehension is generally behind that of their neurotypical peers. Typically people with HFA use less emotional content in speech and are less able to interpret non-verbal cues, such as when listeners are bored with or distracted from the topic of conversation. I would like to make one thing clear however and that is High-functioning autism is not a recognized diagnosis in the DSM-IV-TR or the ICD-10.
