Much developmental work has been devoted to scalar implicatures. These are implicitly communicated propositions linked to relatively weak terms (consider how Some pragmatically implies Not all) that are more likely to be carried out by adults than by children. Children tend to retain the linguistically encoded meaning of these terms (wherein Some is compatible with All). In three experiments, we gauge children's performance with scalars while investigating four factors that can have an effect on implicature production: (i) the role of (the presence or absence of) distractor items; (ii) the nature of the task (verbal judgments versus action-based judgments); (iii) the choice of scalar expression (the French quantifier quelques versus certains); and (iv) the type of scale that contextualizes the weak utterance (the affirmative All versus the negative None earlier findings showing that 9-year-olds are more likely than adults to consider as true statements such as Some turtles are in the boxes (uttered when all turtles are in the boxes) while employing the quantifier certains in a truth evaluation task containing multiple distractor items. The task in Experiment 2 increased implicature production across all ages (4-, 5-, and 7-year-olds as well as adults) but maintained the developmental effect while using quelques in an action-based task containing no distractor items. Experiment 3 showed that 9-year-olds are more likely to produce implicatures with quelques than they are with certains in the action task while adults are not affected by the choice of term. Overall, these results identify seemingly harmless task features that can prevent even older children (9-year-olds) from carrying out implicatures (e.g., through the inclusion of distractors) while also showing how implicature production among even young children (4-to 5-year-olds) can be facilitated by task features (e.g., the use of an action task) and without the introduction of special training.
Over the last decade, various proposals have been made for supplanting the classical Gricean theory of scalar implicature with conventionalist (i.e. lexicalist or syntax-based) treatments. In contradistinction to the classical view, conventionalist theories predict that scalar inferences occur systematically and freely in embedded positions. We present experimental evidence that disproves this prediction, arguing along the way that there are rather good reasons to suspect that introspection isn't always a reliable tool for gathering data on pragmatic inferences.
Many experimental studies from the 70s and 80s show that children do not understand metaphors until fairly late in development (not until adolescence, some claim). I will argue that children’s metaphorical abilities may not be as weak as they first appear. Findings suggesting a poor comprehension of metaphor by young children might be better explained by factors other than purportedly inadequate pragmatic abilities. Furthermore, attested cases of metaphor production by children have often been re-analysed either as cases of overextension (i.e., erroneous extension of the term’s conventional denotation) or as cases of pretence, and are thus not considered to be genuine metaphors. I would like to explore the hypothesis that such re-analyses do not preclude the possibility that young children possess the necessary abilities to produce metaphors. Instead, some aspects of overextension and pretence may pave the way to metaphorical abilities.
To assess children's cognitive capacities to understand (rather than explain or paraphrase) metaphors, we investigated how 3-year-olds (n=36; 3;0-3;3) fare with novel metaphors corresponding to their world knowledge and linguistic competences using a behavioural choice paradigm. In a game, participants had to give the experimenter one of two objects referred to by a metaphorical expression. Unlike what previous literature suggests, our results indicate that 3-year-olds are able to understand novel metaphors that are appropriate for their vocabulary and world knowledge, based on action measures rather than metalinguistic responses. We discuss how factors other than incompetence with pragmatic inferencing can explain difficulties with metaphor comprehension.
Metaphor understanding is traditionally thought to emerge late in childhood. Although recent findings suggest that even pre-schoolers can understand metaphor in more age appropriate paradigms, it is still unclear which skills scaffold the development of metaphorical abilities. Metaphor comprehension is a complex process relying on multiple cognitive abilities with different developmental paths, such as Alternative Naming (i.e., accepting two labels for the same referent) and Analogy Perception (i.e., detecting similarities across objects). These two abilities may prove crucial to explain the development of metaphoric competence because difficulties in one or both of them may impose additional demands linked to children's general cognitive development. This might contribute to slow down the development of metaphor understanding. This study aims at teasing apart the contribution of Alternative Naming and Analogy Perception in the development of metaphor understanding. Using a unified picture-matching paradigm, we tested 3-and 4-year-olds in three tasks: Metaphor Comprehension, Alternative Naming and Analogy Perception. Results reveal that children with better alternative naming and analogical abilities show a better performance in the metaphor task, suggesting that both Alternative Naming and Analogy Perception play a role in the development of metaphoric competence.
Background and aims Difficulties with aspects of morphosyntax, phonology and/or vocabulary are the hallmark of Development Language Disorder (DLD). Yet, little is known about the linguistic-pragmatic abilities of young children with DLD. Previous studies suggest that children with DLD are experiencing difficulties with idioms, sayings and slang expressions, often interpreting them in a literal or unconventional fashion. However, it is unclear whether this is caused by difficulties to make pragmatic inferences in general or whether it stems from their semantic abilities. We therefore investigated novel metaphor understanding in young children with and without DLD. Methods We assessed novel metaphor comprehension using a reference assignment task with 15 children with DLD diagnoses (ages 42–49 months) as well as typically developing peers matched on chronological age (n = 15) and on language (n = 15). Results Children with DLD performed worse than their age-matched peers but in a comparable manner to the (younger) language-matched typically developing children. Performance was not related to non-verbal intelligence in the children with DLD. Conclusion The findings indicate that young children with DLD have difficulties with metaphor comprehension but also suggest that these difficulties are in line with their general language difficulties and linked to their overall linguistic competence rather than reflecting additional specific issues with deriving pragmatic inferences. Implications Our study adds to a growing body of literature showing that children with low language abilities are also likely to display more difficulties in understanding figurative language independently of any other symptomatology of their clinical diagnosis. It also supports the argument that deficits in the pragmatic domain are a secondary impairment rather than a core deficit in children with DLD. Nonetheless, children with DLD do show difficulties in understanding metaphors. Understanding figurative language is necessary for everyday communication and should therefore be targeted alongside traditional treatments by clinicians treating children with DLD.
Any form of overt communication, be it gestural or linguistic, involves pragmatic skills. This article investigates the social–cognitive foundations of pragmatic development from infancy to late childhood and argues that it is driven by, among other things, the emergence of the capacities to assess the communicator's competence (e.g. perceptual access, epistemic states) and honesty. We discuss the implications of this proposal and show how it sheds new light on the developmental trajectory of a series of pragmatic phenomena, with a specific focus on the development of irony comprehension.
