Abstract

Pragmatic phenomena are characterized by extreme variability, which makes it difficult to draw sound generalizations about the role of social cognition in pragmatic language by and large. I introduce cultural evolutionary pragmatics as a new framework for the study of the interdependence between language and social cognition, and point at the study of common-ground management across languages and ages as a way to test the reliance of pragmatic language on social cognition. I illustrate this new research line with three experiments on article use by second language speakers, whose mother tongue lacks articles. These L2 speakers are known to find article use challenging and it is often argued that their difficulties stem from articles being pragmatically redundant. Contrary to this view, the results of this exploratory study support the view that proficient article use requires automatizing basic socio-cognitive processes, offering a window into the interdependence between language and social cognition.

Abstract

How might social cognition help us communicate through language? At what levels does this interaction occur? In classical views, social cognition is independent of language, and integrating the two can be slow, effortful, and error-prone. But new research into word level processes reveals that communication
is brimming with social micro-processes that happen in real time, guiding even the simplest choices like how we use adjectives, articles, and demonstratives. We interpret these findings in the context of advances in theoretical models of social cognition and propose a Communicative Mind-Tracking
framework, where social micro-processes aren’t a secondary process in how we use language—they are fundamental to how communication works.

Abstract

It has been generally assumed in the Theory of Mind literature of the past 30 years that young children fail standard false-belief tasks because they attribute their own knowledge to the protagonist (what Leslie and colleagues called a “true-belief default”). Contrary to the traditional view, we have recently proposed that the children's bias is task induced. This alternative view was supported by studies showing that 3 year olds are able to pass a false-belief task that allows them to focus on the protagonist, without drawing their attention to the target object in the test phase. For a more accurate comparison of these two accounts, the present study tested the true-belief default with adults. Four experiments measuring eye movements and response inhibition revealed that (a) adults do not have an automatic tendency to respond to the false-belief question according to their own knowledge and (b) the true-belief response need not be inhibited in order to correctly predict the protagonist's actions. The positive results observed in the control conditions confirm the accuracy of the various measures used. I conclude that the results of this study undermine the true-belief default view and those models that posit mechanisms of response inhibition in false-belief reasoning. Alternatively, the present study with adults and recent studies with children suggest that participants' focus of attention in false-belief tasks may be key to their performance.

Abstract

In standard Theory of Mind tasks, such as the Sally-Anne, children have to predict the behaviour of a mistaken character, which requires attributing the character a false belief. Hundreds of developmental studies in the last 30 years have shown that children under 4 fail standard false-belief tasks. However, recent studies have revealed that bilingual children and adults outperform their monolingual peers in this type of tasks. Bilinguals’ better performance in false-belief tasks has generally been interpreted as a result of their better inhibitory control; that is, bilinguals are allegedly better than monolinguals at inhibiting the erroneous response to the false-belief question. In this review, I challenge the received view and argue instead that bilinguals’ better false-belief performance results from more effective attention management. This challenge ties in with two independent lines of research: on the one hand, recent studies on the role of attentional processes in false-belief tasks with monolingual children and adults; and on the other, current research on bilinguals’ performance in different Executive Function tasks. The review closes with an exploratory discussion of further benefits of bilingual cognition to Theory of Mind development and pragmatics, which may be independent from Executive Function.

Abstract

Categorisation models of metaphor interpretation are based on the premiss that categorisation statements (e.g., ‘Wilma is a nurse’) and comparison statements (e.g., ‘Betty is like a nurse’) are fundamentally different types of assertion. Against this assumption, we argue that the difference is merely a quantitative one: ‘x is a y’ unilaterally entails ‘x is like a y’, and therefore the latter is merely weaker than the former. Moreover, if ‘x is like a y’ licenses the inference that x is not a y, then that inference is a scalar implicature. We defend these claims partly on theoretical grounds and partly on the basis of experimental evidence. A suite of experiments indicates both that ‘x is a y’ unilaterally entails that x is like a y, and that in several respects the non-y inference behaves exactly as one should expect from a scalar implicature. We discuss the implications of our view of categorisation and comparison statements for categorisation models of metaphor interpretation.

Abstract

Over two decades, the director task has increasingly been employed as a test of the use of Theory of Mind in communication, first in psycholinguistics and more recently in social cognition research. A new version of this task was designed to test two independent hypotheses. First, optimal performance in the director task, as established by the standard metrics of interference, is possible by using selective attention alone, and not necessarily Theory of Mind. Second, pragmatic measures of Theory-of-Mind use can reveal that people actively represent the director’s mental states, contrary to recent claims that they only use domain-general cognitive processes to perform this task. The results of this study support both hypotheses and provide a new interactive paradigm to reliably test Theory-of-Mind use in referential communication.

Abstract

Bilingualism can have widespread cognitive effects. In this article we investigate whether bilingualism might have an effect on adults' abilities to reason about other people's beliefs. In particular, we tested whether bilingual adults might have an advantage over monolingual adults in false-belief reasoning analogous to the advantage that has been observed with bilingual children. Using a traditional false-belief task coupled with an eye-tracking technique, we found that adults in general suffer interference from their own perspective when reasoning about other people's beliefs. However, bilinguals are reliably less susceptible to this egocentric bias than are monolinguals. Moreover, performance on the false-belief task significantly correlated with performance on an executive control task. We argue that bilinguals' early sociolinguistic sensitivity and enhanced executive control may account for their advantage in false-belief reasoning.
