High prevalence of autism spectrum disorders has been reported in 22q11.2DS, although this has been based solely on parent report measures. This study describes the presence of ASD using a procedure more similar to that used in clinical practice by incorporating history AND a standardized observation measure and suggests that ASD is not as common as previously reported in 22q11.2DS. Differences in methodology, along with comorbid conditions such as anxiety, likely contribute to false elevations in ASD prevalence and information from multiple sources should be included in the evaluation of ASD. © 2013 Springer Science+Business Media New York.

Classical logic and a given nonclassical logic are, by definition, incompatible in some sense. In some cases, this incompatibility is innocuous. In other cases, the nonclassical logic is incompatible with classical logic on a fundamental level, such that the two logics can be seen as rival theories of logical entailment and only one of them can succeed. I will explore the structure of these cases of logical rivalry by considering three examples: Dummett’s antirealism, Putnam’s response to results of quantum mechanics, and Tye’s response to vagueness. I will show that, despite the differences between these cases’ motivations and methods, they nevertheless all conform to a particular framework in challenging classical logic. Moreover, these diverse cases all characterize classical logic as the result of an unwarranted generalization from a limited and apparently privileged realm of entailment
