In this Symposium we link different perspectives and traditions of research on language and concepts in the cognitive sciences to better understand the process of abstraction from the social-interactive standpoint. In contrast to the usual benefits of abstraction – such as the ability to categorize and generalize – we underscore the possibility of abstract concepts and words to remain underspecified, “open to the context, the suggestions of others” (Borghi, 2023) or to processes of real-time negotiations (Christiansen & Chater, 2022). This is enabled by their largely non-perceptual rela-tional character (Gentner, 2005) and by the fact that they arise in cognitive systems continually embedded and active in their environments (Cisek 1999; Mannella & Tummolini 2023).

Are abstract sentences associated with specific constructs in dialogue, i.e., higher uncertainty, more curiosity and willingness to continue a conversation, and more causal questions? In three preregistered experiments we address these questions asking participants to evaluate the plausibility of linguistic exchanges referred to concrete and abstract concepts. Results support theories proposing that abstract concepts involve more inner monitoring and social dynamics compared to concrete concepts, and suggest that reaching alignment in dialogue is more effortful with abstract than with concrete concepts.

Contrasting the climate change emergency represents one of the major challenges of modern times. Knowing how people represent ecology-related phenomena is crucial to inform interventions aimed at promoting more effective pro-environmental behaviors. Despite this, literature on the topic is still scarce. To fill this gap, we asked 340 participants to rate 200 concepts—among which Ecological (N = 50, e.g., deforestation)—on numerous semantic dimensions (N = 39), drawing insights from the literature on conceptual organization. A Principal Component Analysis on our dataset revealed the presence of three major components explaining overall the variability of our set of concepts. Interestingly, Ecological concepts had a major role in all of them. Indeed, when compared to other conceptual categories—both related (i.e., Natural—e.g., water—and Geographical/Geopolitical—e.g., ocean, city) and not related (i.e., Technological—e.g., Internet) to the green domain—they figured among the most abstract (Component 1), impacting our political, social, and personal spheres (Component 2), scientific, emotionally charged, and evoking sensorimotor experiences (Component 3) concepts. Overall, our study has a threefold relevance. On a theoretical side, it can contribute to enriching theories on concepts by investigating a new semantic domain that jeopardizes the concrete-abstract dichotomy; on a scientific side, it might broaden categorization research by providing semantic norms for new conceptual domains (the TECo Database); on a societal side, it can enhance politics on these timely themes.

This study investigates vocal congruence across populations with different gender identities. Forty-four participants completed a self-voice perception task in three conditions (Silent Reading, Reading Aloud, and Listening to their recorded voice) after reading gender-stereotyped priming texts. Our findings show that transgender and gender non-conforming participants experience lower vocal congruence listening to their outer voice compared to cisgender participants, and they perceive their inner voice as more congruent to the self. Results confirm the role of interoceptive sensibility on general voice congruence perception, suggesting that it varies across gender identities. Further research is needed to deepen the relationship between inner experience and voice perception and to disentangle the reciprocal relationship between self-identity and self-voice perception.

Perturbations to the speech articulators induced by frequently using an interfering object during infancy (i.e., pacifier) might shape children's language experience and the building of conceptual representations. Seventy-one typically developing third graders performed a semantic categorization task with abstract, concrete and emotional words. Children who used the pacifier for a more extended period were slower than the others. Moreover, overusing the pacifier increased response time of abstract words, whereas emotional and (above all) concrete words were less affected. Results support the view that abstract words are grounded both in perception-action and in linguistic experience.

Investigating how people represent the natural environment and abstract it into geographical (e.g., mountain) and geopolitical (e.g., city) categories is pivotal to comprehending how they move and interact with the places they inhabit. Yet, the conceptualization of geographical and geopolitical domains has received scant attention so far. To deal with that, we reviewed 50 articles tackling this topic. Most studies have focused on assessing the universality of these concepts—especially geographical ones—mainly using free-listing and ethnophysiographic methods. Current perspectives tend to favor a non-universalistic characterization of these kinds of concepts, emphasizing their high cross-linguistic and cross-cultural variability, especially when compared to other semantic domains. Since geographical and geopolitical features are not pre-segmented by nature, the role of categories imposed by humans is crucial for these concepts. Significantly, their variability does not only depend on “cross” differences: evidence suggests that the cognitive demand requested by the task, idiosyncratic characteristics of individuals such as expertise level, and the typology of inhabited environments are further factors impacting the conceptual flexibility of these domains. Exploring the factors influencing our understanding of geographical and geopolitical categories can provide valuable insights for instructing effective communication policies to enhance sustainable development and address ecological emergencies, taking into consideration diverse cultural backgrounds within different populations.

Gender can be considered an embodied social concept encompassing biological and cultural components. In this study, we explored whether the concept of gender varies as a function of different cultural and linguistic norms by comparing communities that vary in their social treatment of gender-related issues and linguistic encoding of gender. In Study 1, Italian, Dutch, and English-speaking participants completed a free-listing task, which showed Italians and Dutch were the most distinct in their conceptualization of gender: Italian participants focused more on socio-cultural features (e.g., discrimination , politics , and power), whereas Dutch participants focused more on the corporeal sphere (e.g., hormones , breasts , and genitals). Study 2 replicated this finding focusing on Italian and Dutch and using a typicality rating task: socio-cultural and abstract features were considered as more typical of "gender" by Italian than Dutch participants. Study 3 addressed Italian and Dutch participants' explicit beliefs about gender with a questionnaire measuring essentialism and constructivism, and consolidated results from Studies 1 and 2 showing that Dutch participants endorsed more essentialist beliefs about gender than Italian participants. Consistent with socio-cultural constructivist accounts, our results provide evidence that gender is conceptualized differently by diverse groups and is adapted to specific cultural and linguistic environments.

While eating is universally salient, food habits vary greatly even across similar western cultural groups. Italians, for example, are renowned pasta consumers whereas this habit is less pervasive in other western cultures. This variability might shape the conceptualization of food of different cultural groups. Against this backdrop, it has been proposed the semantic representation of food is universally organized along two main axes, with natural food (e.g., vegetables, fruit) relying more on sensory properties and manufactured food (e.g., pasta) relying more on functional properties. In this exploratory study, we compared the semantic representation of pasta, vegetables, and fruit across Italian and English-speaking participants with a free-listing task. We find the representation of pasta is not restricted to functional properties. Moreover, Italian and English speakers differed both quantitatively and qualitatively in their representation of pasta. Italians produced more exemplars of pasta than English-speaking participants, and their conceptual organization of pasta also included fine-grained distinctions (e.g., egg-based vs. flour-and-water pasta), whereas English-speaking participants mostly focused on perceptual components (e.g., long) – even when accounting for differential consumption, cooking, and preparation experience of pasta. Our results suggest that culture-specific experiences can shape the conceptualization of food. [ABSTRACT FROM AUTHOR]

Abstract domains of knowledge may have social origins. However, whether abstract concepts (ACs) may also differentially affect communicative interaction and conversation has not been explored. Here, we studied ACs' communicative functions by collecting in an Italian and an English sample, ratings for concrete concept (CC) and ACs related to three main dimensions: communicative/pragmatic [i.e., Openness to Negotiation (ON), Easiness to Start a Conversation (ESC)], semantic/metacognitive [i.e., Social Metacognition (SM) – perceived need of others, Word Confidence (WC), Contextual Availability (CA)], and emotional–experiential (i.e., Pleasantness, Valence, Familiarity). Overall, Italian participants judged it was easier to start a conversation, the more pleasant, familiar, and positively valenced were rated the concepts. Crucially, at lower values of the emotional–experiential component (i.e., Familiarity in the Italian sample, also Pleasantness and Valence in an English sample), there was an advantage of ACs over CCs in the ESC. Moreover, in the Italian sample, participants rated ACs higher on SM, ON, and lower on WC and CA. Notably, in both the Italian and English sample, ACs with higher ratings on the ESC dimension belonged to the Self-Sociality subcluster. The results offer new insights into the pragmatic aspects linked to ACs' use. [ABSTRACT FROM AUTHOR]

Flexible screen-printing technology combined with the use of a nano/material coating for improving electrode functionalities boosted the manufacturing of highly sensitive electrochemical sensors addressing the need for fast and easy-to-handle tests in different application fields. However, due to the large-scale production and disposable and single-use nature of these devices, their environmental footprint should be taken into careful consideration. Herein, the innovative reuse of post-consumer polyethene terephthalate (PET) plastics as an alternative substrate coupled with biochar as an environmentally friendly and cost-effective modifier is described as a sustainable alternative for the production of robust electrochemical sensors. The good printability of reused plastics with graphite inks despite the chemical heterogeneity, different crystallinity, and surface roughness was demonstrated using atomic force microscopy and attenuated total reflection Fourier transform infrared spectroscopy. Functionalization with brewers' spent grain biochar enabled the fabrication of highly performing electrochemical sensors for nitrite detection in water having a limit of detection and a limit of quantification of 3.3 nM and 10.3 nM, respectively, with a linear range spanning from 0.01 to 500 μM, and good reproducibility (RSD% 8%). The innovative intervention of the biochar-multilayer system markedly enhanced the electron transfer process at the electrode interface while simultaneously serving as an absorptive material for the investigated analyte. This work lays a foundation for repurposing end-of-life plastics for the electronics industry and presents a customizable reuse strategy aimed to keep the value of plastics in the economy and reduce waste and leakage into the natural environment.
