Longitudinal associations between theory of mind and metaphor understanding during middle childhood

The Impact of Metaphors on Academic Text Comprehension: The Case of Students With Dyslexia

Metaphor has long been used by scholars to make concepts more comprehensible. However, this use of figurative language has never been investigated in relation to the way students with dyslexia learn from academic texts. This study aims to assess the impact of metaphors on overall academic text comprehension in university students with and without dyslexia. Excerpts from scientific articles containing metaphors were adapted to be presented in two comparable conditions: metaphorical and literal. Legibility indexes were controlled for to guarantee the same difficulty between conditions. Twenty-eight students with dyslexia and thirty students without dyslexia underwent a multiple-choice comprehension task for two texts, one for each condition, and provided evaluations of text perception. A standardised assessment of general reading comprehension and cognitive abilities, such as reading speed, reading accuracy, and working memory was conducted. Data revealed that, when reading ability was controlled for, students with dyslexia presented significantly lower comprehension scores only in texts containing metaphors, despite comparable perceived complexity and increased interest in metaphorical texts. These findings suggest that metaphors used in educational discourse may not be entirely inclusive, as they seem to impose additional cognitive demands on students with dyslexia.

Weighing the role of social cognition and executive functioning in pragmatics in the schizophrenia spectrum: A systematic review and meta-analysis

Pragmatic impairment is diffused in schizophrenia spectrum disorders, but the literature still debates its neurocognitive underpinnings. This systematic review and meta-analysis aimed to investigate the neurocognitive correlates of pragmatic disorders in schizophrenia and determine the weight of social cognition and executive functioning on such disorders. Of the 2,668 records retrieved from the literature, 16 papers were included in the systematic review, mostly focused on non-literal meanings and discourse production in schizophrenia. Ten studies were included in the meta-analysis: pragmatics was moderately associated with both social cognition and executive functions (especially inhibition), but the link with social cognition was stronger. The mediation analysis showed that social cognition mediated the relationship between executive functions and pragmatics. Based on this, we proposed a hierarchical neurocognitive model where pragmatics stems from social cognition, while executive functions are the fertile ground supporting the other two domains, and we discuss its theoretical and clinical implications.

A metaphorical advantage for bilingual children? Understanding figurative meaning by L2 and L3 EFL learners

This study compared school-aged monolingual and bilingual English-as-a-foreign-language (EFL) learners in terms of understanding metaphors on recall, multiple-choice, and reasoning tasks. It also examined the relationship between cognitive capacity and understanding metaphors on different measures. A hundred and thirty Persian-Turkish early bilinguals and 122 monolingual Persian-speaking EFL learners took three different tests of metaphor comprehension and the Figural Intersections Test, a test of cognitive capacity. Bilinguals outperformed monolinguals in terms of cognitive capacity and understanding metaphors on two of the tasks, though with a small effect size. Furthermore, there was a significant positive relationship between cognitive capacity and the scores on the multiple-choice and reasoning tests, but not the recall test. Results suggest that bilingual L3 learners have an edge in understanding metaphors, reflecting a cognitive advantage.

Perspective-taking in deriving implicatures: The listener's perspective is important too

Theories of meaning propose that listeners understand a speaker's implicit meaning thanks to mutually assumed norms of conversation that take into account what the speaker has said, as well as contextual factors, including what the speaker knows. Emerging psycholinguistic research shows that listeners derive a particular kind of implicit meaning, quantity implicatures, when their speaker is knowledgeable about the situation but tend to not derive it otherwise. In this article we focus on if and how listeners use the knowledge that is available only to themselves, i.e., the listener's perspective, while deriving implicatures. To do so, we explore the derivation of ad hoc quantity implicature in situations where the speaker does or does not have full knowledge, while, in the latter case, the listener has two types of privileged knowledge. Two versions of a study with neurotypical English-speaking adults show that listeners are influenced by their own perspective while deriving implicatures, depending on the type of knowledge available to them. We discuss the implications of these findings for models of pragmatic interpretative strategies.

The relationship between metaphor skills and Theory of Mind in middle childhood: Task and developmental effects

Theoretical pragmatics in the post-Gricean tradition argued that metaphor requires understanding of how another person sees the world. Yet, it is unclear what role mindreading plays in developing metaphor skills. Here we examined the relationship between metaphor and Theory of Mind (ToM) in middle childhood by using two different tasks. In addition to the Physical and Mental Metaphors task (PMM), based on the verbal explanation of physical and mental metaphors, we revived the Referential Metaphors task for children (Noveck, Bianco, & Castry, 2001), where metaphorical and literal referents are presented in a narrative context. The sample included 169 8-, 9-, and 10-year-old children, assessed also for ToM (via the Strange Stories) and other linguistic and cognitive skills as control variables. In the PMM, ToM supported the understanding of mental (but not physical) metaphors in 9-year-olds only, whereas in the Referential Metaphors task ToM supported accuracy of understanding metaphors (but not literal items) in younger children as well. At age 10, ToM effects were negligible in both tasks. These findings suggest that ToM has a task-specific role in metaphor, linked to the characteristics of the items in the task at stake, being for instance greater for metaphors with mental (compared to physical) content and for non-literal (compared to literal) referents. The findings also suggest that the relationship between ToM and metaphor skills is developmental sensitive, as children start to capitalize on ToM earlier in development when the metaphor context is richer, and these effects fade with age. Theoretically, these data argue in favor of the relevance-theoretic account of metaphor, spelling out different ways in which ToM might support metaphor resolution across tasks, for instance by providing better access to the psychological lexicon (i.e., terms referring to mental states) and better context processing, serving as a springboard to achieve sophisticated pragmatic skills in middle childhood.

Children's processing of written irony: An eye-tracking study

Ironic language is challenging for many people to understand, and particularly for children. Comprehending irony is considered a major milestone in children's development, as it requires inferring the intentions of the person who is being ironic. However, the theories of irony comprehension generally do not address developmental changes, and there are limited data on children's processing of verbal irony. In the present pre-registered study, we examined, for the first time, how children process and comprehend written irony in comparison to adults. Seventy participants took part in the study (35 10-year-old children and 35 adults). In the experiment, participants read ironic and literal sentences embedded in story contexts while their eye movements were recorded. They also responded to a text memory question and an inference question after each story, and children's levels of reading skills were measured. Results showed that for both children and adults comprehending written irony was more difficult than for literal texts (the "irony effect") and was more challenging for children than for adults. Moreover, although children showed longer overall reading times than adults, processing of ironic stories was largely similar between children and adults. One group difference was that for children, more accurate irony comprehension was qualified by faster reading times whereas for adults more accurate irony comprehension involved slower reading times. Interestingly, both age groups were able to adapt to task context and improve their irony processing across trials. These results provide new insights about the costs of irony and development of the ability to overcome them.

Metaphor production in the bilingual acquisition of English and Polish

Metaphor acquisition research has focused mostly on metaphor comprehension in monolingual children. Ours is the first study to examine metaphor production in young bilinguals. A quantitative method was employed whereby sixty-two children aged three to six, with English and Polish, were tested on their ability to produce primary (e.g., a long day) and perceptual resemblance metaphors (e.g., You're my sunshine) in response to elicitation tasks. A univariate ANOVA revealed that the main factors to affect the production of conventional metaphors in bilingual children are their chronological age and their verbal skills in both English and Polish. No significant effect was found for nonverbal IQ, metaphor type, or testing language. These results are discussed in the context of both Conceptual Metaphor Theory, which has been concerned with the study of primary (and other conceptual) metaphors, and Structure Mapping Theory, which has focused on the use of perceptual resemblance metaphors. Usage-Based Theory is brought in to explain lexical effects in metaphor production.

Assessing the construct validity of a theory of mind battery adapted to Tunisian school-aged children

Background

Theory of mind (ToM) refers to the ability to understand others' states of mind, desires, emotions, beliefs, and intentions to predict the content of their mental representations. Two major dimensions within ToM have been studied. The first is the type of inferred mental state, which can be cognitive or affective. The second comprises the types of processes involved according to their degree of complexity (first- and second-order false belief and advanced ToM). ToM acquisition is fundamental-a key component in the development of everyday human social interactions. ToM deficits have been reported in various neurodevelopmental disorders through various tools assessing disparate facets of social cognition. Nevertheless, Tunisian practitioners and researchers lack a linguistically and culturally appropriate psychometric tool for ToM assessment among school-aged children.

Objective

To assess the construct validity of a translated and adapted French ToM Battery for Arabic-speaking Tunisian school-aged children.

Methods

The focal ToM Battery was designed with neuropsychological and neurodevelopmental theory and composed of 10 subtests distributed evenly in three parts: Pre-conceptual, cognitive, and affective ToM. Translated and adapted to the Tunisian sociocultural context, this ToM battery was individually administered to 179 neurotypical Tunisian children (90 girls and 89 boys) aged 7-12 years.

Results

After controlling for the age effect, construct validity was empirically confirmed on two dimensions (cognitive and affective) via structural equation modeling (SEM) analysis, demonstrating that this solution has a good fit. The results confirmed that the age affected differentially the performance obtained on ToM tasks based on the two components of the battery.

Conclusion

Our findings confirm that the Tunisian version of the ToM Battery has robust construct validity for the assessment of cognitive and affective ToM in Tunisian school-aged children; hence, it could be adopted in clinical and research settings.

N400 differences between physical and mental metaphors: The role of Theories of Mind

Whether Theory of Mind (ToM) contributes to metaphor understanding has been largely investigated in language acquisition and decay. Yet we know very little about the role of ToM in real-time processing of metaphors in neurotypical adults. Here, we tested the relationship between ToM and metaphor through Event Related Potentials (ERPs) by capitalizing on the difference between metaphors inviting inferences on physical (Boxers are pandas) vs. mental aspects (Teachers are books). Physical metaphors involved a larger and sustained negativity compared to mental ones. This pattern resembled concreteness effects and suggests that physical metaphors may benefit from both verbal and perceptual information. Moreover, higher scores in the Reading the Mind in the Eyes Test (RMET), but not in the Animation task, were associated with a reduction of the N400 amplitude for both physical and mental metaphors. When exploring the ERP temporal trajectory with Generalized Additive Mixed Modeling, earlier differences between metaphors characterized individuals with higher RMET scores. Among the various ToM components, thus, emotion recognition seems to be involved in the processing of metaphors in general, with an earlier impact on the mental type. These findings highlight the multifaceted nature of metaphor, at the crossroad of language, social and perceptual experience.

It is time to address language disorders in schizophrenia: A RCT on the efficacy of a novel training targeting the pragmatics of communication (PragmaCom)

INTRODUCTION

Language and communication disruptions in schizophrenia are at the center of a large body of investigation. Yet, the remediation of such disruptions is still in its infancy. Here we targeted what is known to be one of the most damaged language domains in schizophrenia, namely pragmatics, by conducting a pragmatics-centered intervention with a randomized controlled trial design and assessing also durability and generalization. To the best of our knowledge, this is the first study with these characteristics.

METHODS

Inspired by the Gricean account of natural language use, we tailored a novel treatment addressing the pragmatics of communication (PragmaCom) and we tested its efficacy in a sample of individuals with schizophrenia randomized to the experimental group or to an active control group. The primary outcome with respect to the efficacy of the PragmaCom was measured by changes in pragmatic abilities (as evaluated with the global score of the Assessment of Pragmatic Abilities and Cognitive Substrates test) from baseline to 12 weeks and at 3-month follow-up. The secondary outcome was measured by changes in metaphor comprehension, abstract thinking, and global functioning from baseline to 12 weeks and at 3-month follow-up.

RESULTS

Relative to the control group, at post-test the PragmaCom group showed greater and enduring improvement in global pragmatic skills and in metaphor comprehension. At follow-up, these improvements persisted and the PragmaCom exerted beneficial effects also on functioning.

CONCLUSIONS

Despite the limited sample size, we believe that these findings offer initial yet encouraging evidence of the possibility to improve pragmatic skills with a theoretically grounded approach and to obtain durable and clinically relevant benefits. We argue that it is time that therapeutic efforts embrace communicative dysfunctions in order to improve illness outcome.

What is the contribution of executive functions to communicative-pragmatic skills? Insights from aging and different types of pragmatic inference

The role of executive functions in supporting the pragmatics of communication has been extensively examined in clinical populations, but is still under-explored in healthy aging. In this study we addressed the role of executive skills, including inhibition, working memory, and cognitive flexibility, in older adults' communicative-pragmatic abilities. Pragmatics was extensively assessed by measuring the understanding of figurative language, narrative texts, humor, and implicatures. A hierarchical regression analysis using composite scores evidenced a global effect of executive functions on communicative-pragmatic abilities, beyond demographic and theory of mind aspects. More fine-grained analyses showed that working memory was the strongest predictor of all pragmatic tasks. Specifically, comprehending narratives and humor seemed to capitalize primarily upon working memory, whereas figurative language and implicatures relied on working memory and to some extent cognitive flexibility. Conversely, inhibition did not stand out as a robust predictor of pragmatics. We argue that working memory allows for the simultaneous consideration of multiple pieces of information needed for pragmatic inferencing, and that only once working memory has played its role other executive aspects, such as cognitive flexibility and inhibition, might come into play. Overall, this study highlights the diverse role of executive skills in pragmatics in aging, and more generally contributes to shed light on pragmatic competence in older adults.
