When we speak, we mean more than we say. In this book Stephen C. Levinson explains some general processes that underlie presumptions in communication.

We use a new model of metarepresentational development to predict a cognitive deficit which could explain a crucial component of the social impairment in childhood autism. One of the manifestations of a basic metarepresentational capacity is a ‘ theory of mind ’. We have reason to believe that autistic children lack such a ‘ theory ’. If this were so, then they would be unable to impute beliefs to others and to predict their behaviour. This hypothesis was tested using Wimmer (...) and Perner’s puppet play paradigm. Normal children and those with Down’s syndrome were used as controls for a group of autistic children. Even though the mental age of the autistic children was higher than that of the controls, they alone failed to impute beliefs to others. Thus the dysfunction we have postulated and demonstrated is independent of mental retardation and specific to autism. (shrink)

This article has two aims. The first is to introduce some novel data that highlight rather surprising pragmatic abilities in autism spectrum disorder (ASD). The second is to consider a possible implication of these data for an emerging empirical methodology in philosophy of language and mind.

This article has two aims. The first is to introduce some novel data that highlight rather surprising pragmatic abilities in autism spectrum disorder (ASD). The second is to consider a possible implication of these data for an emerging empirical methodology in philosophy of language and mind. In pursuing the first aim, we expect our main audience to be clinicians and linguists interested in pragmatics. It is when we turn to methodological issues that we hope to pique the interest of philosophers. (...) Still, the methodological issue becomes pressing precisely because of the empirical finding—thus the first part is important for the philosophical readers as well. The game plan is as follows. Given our intended dual audience, we begin with background on autism and pragmatics. Some of this material will be familiar to some of our readership, but few will know all of it. (Those who do are invited to skip these sections.) We then present some results from our pilot study on a corpus of speech by people with ASD. The heart of our finding is that certain speakers with ASD, who have severe trouble with familiar pragmatic phenomena such as metaphor and conversational implicature, exhibit surprising abilities with respect to what is often called “pragmatic determinants of what is said.” We turn next to a possible implication of this finding: It seems to suggest that hitherto seemingly promising evidence from ASD about the semantics/pragmatics boundary is..

Pragmatic deficits of persons with autism spectrum disorders [ASDs] are often traced back to a dysfunction in Theory of Mind. However, the exact nature of the link between pragmatics and mindreading in autism is unclear. Pragmatic deficits in ASDs are not homogenous: in particular, while inter-subjective dimensions are affected, some other pragmatic capacities seem to be relatively preserved. Moreover, failure on classical false-belief tasks stems from executive problems that go beyond belief attribution; false-belief tasks require taking an alternative perspective on (...) the reality. While this capacity is functional in typically developing young children, it is impaired in ASDs. Typically developing children are capable of taking their interlocutor's perspective into account when communicating, whereas poor cognitive flexibility makes it difficult for persons with ASDs to grasp the inter-subjective character of communicative stimuli. This analysis predicts that those pragmatic processes that amount to merely taking into account salient contextual facts during utterance interpretation, without necessarily adopting the interlocutor's perspective, may be preserved in ASDs.
