 In the 1970s, a popular autism researcher named Lorna Wing developed the triad of impairments to explain the signs of Asperger's syndrome in children. The triad has three different but important aspects to it. The first being communication and language difficulties characterised by difficulty understanding and using both non-verbal and verbal communication. The second aspect is difficulties with social interaction. This means that they find it extremely hard to understand social behaviour and this can impact their ability to make friends, develop relationships and develop healthy relationships with their co-workers.
