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

This study investigated the extent to which 3- and 4-year-old children may rely on associative memory representations to pass an unexpected-contents false-belief task. In Experiment 1, 4-year-olds performed at chance in both a standard Smarties task and a modified version highlighting the secrecy of the contents of the tube. These results were interpreted as evidence that having to infer the answer to a false-belief question (without relying on memory representations) is generally difficult for preschool children. In Experiments 2a, 2b, and 2c, 3-year-olds were tested at 3-month intervals during their first year of preschool and showed better performance in a narrative version of the Smarties task (chance level) than in the standard version (below-chance level). These children performed even better in an associative version of the narrative task (above-chance level) where they could form a memory representation associating the protagonist with the expected contents of a box. The results of a true-belief control suggest that some of these children may have relied on their memory of the protagonist’s preference for the original contents of the box (rather than their understanding of what the protagonist was expecting to find inside). This suggests that when 3-year-olds passed the associative unexpected-contents task, some may have been keeping track of the protagonist’s initial preference and not only (or not necessarily) of the protagonist’s false belief. These results are interpreted in the light of current accounts of Theory of Mind development and failed replications of verbal false-belief tasks.

Abstract

The Violation-of-Expectation paradigm is a widespread paradigm in infancy research that relies on looking time as an index of surprise. This methodological review aims to increase the reliability of future VoE studies by proposing to standardize reporting practices in this literature. I review 15 VoE studies on false-belief reasoning, which used a variety of experimental parameters. An analysis of the distribution of p-values across experiments suggests an absence of p-hacking. However, there are potential concerns with the accuracy of their measures of infants’ attention, as well as with the lack of a consensus on the parameters that should be used to set up VoE studies. I propose that (i) future VoE studies ought to report not only looking times (as a measure of attention) but also looking-away times (as an equally important measure of distraction); (ii) VoE studies must offer theoretical justification for the parameters they use, and (iii) when parameters are selected through piloting, pilot data must be reported in order to understand how parameters were selected. Future VoE studies ought to maximize the accuracy of their measures of infants’ attention since the reliability of their results and the validity of their conclusions both depend on the accuracy of their measures.

Abstract

There is an ongoing debate, both in philosophy and psychology, as to whether people are able to automatically infer what others may know, or whether they can only derive belief inferences by deploying cognitive resources. Evidence from laboratory tasks, often involving false beliefs or visual-perspective taking, has suggested that belief inferences are cognitively costly, controlled processes. Here we suggest that in everyday conversation, belief reasoning is pervasive and therefore potentially automatic in some cases. To test this hypothesis, we conducted two pre-registered self-paced reading experiments (N1 = 91, N2 = 89). The results of these experiments showed that participants slowed down when a stranger commented ‘That greasy food is bad for your ulcer’ relative to conditions where a stranger commented on their own ulcer or a friend made either comment – none of which violated participants’ common-ground expectations. We conclude that Theory of Mind models need to account for belief reasoning in conversation as it is at the center of everyday social interaction

Abstract

A pragmatic account of referential communication is developed which presents an alternative to traditional Gricean accounts by focusing on cooperativeness and efficiency, rather than informativity. The results of four language-production experiments support the view that speakers can be cooperative when producing redundant adjectives, doing so more often when color modification could facilitate the listener's search for the referent in the visual display (Experiment 1a). By contrast, when the listener knew which shape was the target, speakers did not produce redundant color adjectives (Experiment 1b). English speakers used redundant color adjectives more often than Spanish speakers, suggesting that speakers are sensitive to the differential efficiency of prenominal and postnominal modification (Experiment 2). Speakers were also cooperative when using redundant size adjectives (Experiment 3). Overall, these results show how discriminability affects a speaker's choice of referential expression above and beyond considerations of informativity, supporting the view that redundant speakers can be cooperative.

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.
