Behavioral evidence concerning memory in forms of high-functioning autism (HFA) and in moderately low-functioning autism (M-LFA) is reviewed and compared. Findings on M-LFA are sparse. However, it is provisionally concluded that memory profiles in HFA and M-LFA (relative to ability-matched controls) are similar but that declarative memory impairments are(More)
We hypothesise that of the two processes underlying declarative memory, recollection is impaired in high-functioning autism (HFA) whereas recollection and familiarity are impaired in low-functioning autism (LFA). Testing these hypotheses necessitates assessing recollection and familiarity separately. However, this is difficult, because both processes(More)
Over the last two decades most psychological and neuropsychological research into autism has focused on individuals with Asperger syndrome or high-functioning autism (HFA), rather than on individuals with lowfunctioning autism (LFA) or what is termed autistic disorder in the Diagnostic and Stastical Manual of Mental Disorders, 4th edition (DSMIV; American(More)

Lack of pretense in children with autism has been explained by a number of theoretical explanations, including impaired mentalising, impaired response inhibition, and weak central coherence. This study aimed to empirically test each of these theories. Children with autism (n = 60) were significantly impaired relative to controls (n = 65) when interpreting(More)
The hypothesis that a pervasive impairment of declarative memory contributes to language impairment in low functioning autism (LFA) was tested. Participants with LFA, high functioning autism (HFA), intellectual disability (ID) without autism, and typical development (TD) were given two recognition tests and four tests of lexical understanding. It was(More)
