Abstract
BACKGROUND: In order to better understand the underlying biological mechanism/s involved in autism, it is important to investigate the cognitive and behavioural phenotypes associated with idiopathic autism (autism without a known cause) and comorbid autism (autism associated with known genetic/biological disorders such as fragile X syndrome). Parental effects associated with each type of autism also serve to cast light on the biological underpinnings of autism. METHOD: Forty-nine participants with idiopathic autism (AD; Mean age: 11.16; SD: 6.08) and their parents (45 mothers; 34 fathers), and 48 participants with fragile X syndrome and co-morbid autism (FXS/AD; Mean age: 17.30; SD: 10.22) a..
