While generic generalisations have been studied by linguists and philosophers for decades, they have only recently become the focus of concentrated interest by cognitive and developmental psychologists, who propose the generics-as-default view. In this paper we focus on the ‘Generic Overgeneralisation’ (GOG) effect proposed by Leslie and colleagues and the native speaker judgments that have been used to support it, and by extension, the generics-as-default view. We take a step back to look at the history of the GOG effect in (...) order to contextualise it. We review existing experimental evidence and discuss four non-mutually exclusive explanations for the GOG effect: ignorance, subkind interpretation, atypical behaviour of all and quantifier domain restriction. We conclude that a closer look at the semantics and pragmatics of generics and universal quantifiers may provide a more nuanced explanation for the pattern of judgment data than that proposed by the generics-as-default view.

Two experiments investigated whether 4- and 5-year-old children are sensitive to whether the content of a generalization is about a salient or noteworthy property (henceforth “striking”) and whether varying the number of exceptions has any effect on children’s willingness to extend a property after having heard a generalization. Moreover, they investigated how the content of a generalization interacts with exception tolerance. Adult data were collected for comparison. We used generalizations to describe novel kinds (e.g., “glippets”) that had either a neutral (...) (e.g., “play with toys”) or a striking property (e.g., “play with fire”) and measured how willing participants were to extend the property to a new instance of the novel kind. Experiment 1 demonstrated that both adults and children show sensitivity to strikingness in that striking properties were extended less than neutral ones, although children extended less than adults overall. The responses of both age groups were significantly different from chance. Experiment 2 introduced varying numbers of exceptions to the generalization made (minimal: 1 exception; maximal: 3 exceptions). Both adults and children extended both types of properties even in the face of exceptions, but to a lower degree than in Experiment 1. Striking properties were extended less than neutral ones, as in Experiment 1. We observed that the greater the number of exceptions, the lower the rates of extension we obtained, for both types of properties in adults, but only with striking properties in children. Children seemed to keep track of varying numbers of exceptions for striking properties, but their performance did not differ from chance. The findings underscore that 4- and 5-year-old children are sensitive to strikingness and to exception tolerance for generalizations and are developing toward an adult-like behavior with respect to the interplay between strikingness and exception tolerance when they learn about novel kinds. We discuss the implications of these results with regards to how children make generalizations. (shrink)

It has been argued that the primary acquisition of genericity in early child speech poses a problem for standard quantificational approaches to generics and instead motivates the claim that generics give voice to an innate, default mode of generalising. This article argues that analogous puzzles involving the acquisition of A‐quantifiers undermine the empirical support for a purely cognition‐based approach to generics. Instead, these acquisition puzzles should be solved by generalising the core insight of the cognitive defaults theory to these expressions, (...) reconciling formal semantic approaches with the role that cognitive development plays on lexical competence.
