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 predicted that recognition would be impaired in the LFA group relative to the HFA and TD groups but not the ID group, and that recognition would correlate with lexical knowledge in the LFA group but none of the other groups. These predictions were supported except that the HFA group performed more similarly to the LFA group than expected, a finding interpreted in terms of selectively impaired episodic memory.

Many accounts of autism spectrum disorder (ASD) imply that the condition's behavioural 'symptoms' are direct reflexes of underlying deficits. In doing so, however, they invariably overlook the social contexts in which symptomatic behaviours occur and are identified as pathological. This study addresses this issue, using conversation analysis (CA) to examine the emergence of inflexibility, a behavioural trait symptomatic of ASD, during play involving an adult and diagnosed child. We argue that 'inflexibility' is the product of the child's strategic attempts to retain control over the unfolding interaction, within a context where such attempts breach normative expectations about adult-child play. Furthermore, it demonstrates that the adult does not resist these attempts, on occasion even explicitly providing opportunity for subsequent inflexibility. This challenges the assumption that ASD's behavioural profile solely represents the endpoint of underlying deficit, and demonstrates how 'non-impaired' speakers can be implicated in the manifestation of symptomatic behaviours.

A distinction has been drawn between basic (pure) conversation analysis (CA) and applied CA. Applied CA has become especially beneficial for informing areas of practice such as health, social care and education, and is an accepted form of research evidence in the scientific rhetoric. There are different ways of undertaking applied CA, with different foci and goals. In this article, we articulate one way of conducting applied CA, that is especially pertinent for practitioners working in different fields. We conceptualise this as Reflective Interventionist CA (RICA). We argue that this approach to applied CA is important because of its emphasis on the reflective stance that is valuable to an understanding of research data, its commitment to collaboration with practitioners, and its inductive style. In this paper, we outline the core premises and benefits of this approach and offer empirical examples to support our argument. To conclude, we consider the implications for evidence-based practice.
