Phillips & Silverstein (P&S, 2003) propose that NMDA-receptor dysfunction may be the fundamental neurobiological mechanism underlying and associating impaired holistic perception and cognitive coordination with schizophrenic psychopathology. We discuss how the P&S hypothesis shares different aspects of the weak central coherence account of autism from both theoretical and experimental perspectives. Specifically, we believe that neither those persons with autism nor those with schizophrenia integrate visuo-perceptual information efficiently, resulting in incongruous internal representations of their external world. However, although NMDA-hypofunction may be responsible for perceptual impairments in schizophrenia and possibly autism, we suggest that it is highly unlikely that NMDA-hypofunction is specifically responsible for the autistic behavioral symptomology, as described by P&S in their target article.

Substantial research efforts have been devoted to developing a cure for autism, but some advocates of people with autism claim that these efforts are misguided and even harmful. They claim that there is nothing wrong with people with autism, so there is nothing to cure. Others argue that autism is a serious and debilitating disorder and that a cure for autism would be a wonderful medical breakthrough. Our goal in this essay is to evaluate what assumptions underlie each of these positions. We evaluate the arguments made on each side, reject those that are implausible and then highlight the key assumptions of those that remain.

The number of people diagnosed with autism has risen exponentially in recent years. Are the diagnostic labels currently in use adequate to describe such a vast range of symptoms? Should we reconsider the appropriateness of the language we use to discuss autism? A mother of two autistic sons describes what the autism label has meant for her and her family.

This paper problematizes contemporary cultural understandings of autism. We make use of the developmental psychology concepts of ‘Theory of Mind’ and ‘mindblindness’ to uncover the meaning of autism as expressed in these concepts. Our concern is that autism is depicted as a puzzle and that this depiction governs not only the way Western culture treats autism but also the way in which it governs everyday interactions with autistic people. Moreover, we show how the concepts of Theory of Mind and mindblindness require autism to be a puzzle in the first place. Rather than treat autism as a puzzle that must be solved, we treat autism as a teacher and thus as having something valuable to contribute toward an understanding of the inherent partiality and uncertainty of human communication and collective life.

Most scientists and theorists concerned with the problem of consciousness focus on our consciousness of the physical world (our sensations, feelings, and awareness). In this paper I consider our consciousness of the mental world (our thoughts about thoughts, intentions, wishes, and emotions).The argument is made that these are two distinct forms of consciousness, the evidence for this deriving from studies of autism. Autism is a severe childhood psychiatric condition in which individuals may be conscious of the physical world but not of the mental world. Relevant experimental evidence is described, including some recent neuroimaging studies pointing towards the neural basis of our consciousness of the mental.

Cognitive developmentalists have had a long-standing interest in neurodevelopmental conditions, such as autism. This is not only out of a desire to understand the causes of such atypical development, in order to advance medical science and develop interventions. It is also because studying the processes that cause atypicality can sometimes throw light on typical development. It is this two-way influence that characterises the field of developmental psychopathology. In this chapter, we focus on autism. We bring out this interaction between what we now understand about autistic cognition, and how this has helped us understand ‘normality’.
