CLUBE DE CIÊNCIAS NA ESCOLA: UMA PROPOSTA DE ESPAÇO PARA APRENDIZAGEM EM EDUCAÇÃO AMBIENTAL
Authors: Alves Rodrigo Henrique Risso Aires
Published: June 2024

O ensino de ciências atravessa mudanças no Brasil. O processo de ensino-aprendizagem vem se aperfeiçoando ao longo dos anos e o professor precisa vivenciar este momento. Mudar o conceito de escola que para muitos alunos é tida como desinteressante, principalmente quando se tem aulas atreladas somente ao uso de livros, representa um desafio ainda maior. Para que este cenário mude, é torna relevante a aquisição de abordagens práticas eficiente e efetivas, de maneira continuada e que realmente tenham potencial educativo, aprimorando características e habilidades que cada estudante já possui. Um destes veículos alternativos que vem sendo utilizados são os clubes de ciências com alto impacto na alfabetização científica. A proposta desta iniciativa foi a implantar um CC em uma escola do ensino médio em Humaitá-AM, buscando alcançar nos alunos o conceito de Educação ambiental, além de outros temas a partir deste. A EA, quando encarada como assunto, pode ser inserida dentro de todas as matérias do currículo, uma vez que sempre existem temas que relacionem homem e o ambiente. A metodologia se configura como pesquisa qualitativa baseada em estudo de caso, auxiliada por um questionário semiestruturado de perguntas fechadas visando encontrar um desenvolvimento de pensamento crítico dos participantes, uma vez que um clube de ciências não é um espaço formal da escola. Dessa maneira, foi possível constatar que a maioria dos alunos demonstraram grande interesse em participar dos encontros e conseguiram manifestar maiores interesses por assuntos sobre o meio ambiente que antes da formação do clube passavam por temas indiferentes.

The potential of classroom video recordings in detecting the TA-to-pupil, teacher-to-TA and peer interactions: An overview
Authors: Boufahja Ines , Wolf Janet , Manenova Martina
Published: June 2024

Technology in the classroom comes in many shapes to differentiate instruction, create meaningful learning experiences, actively engage the learners, or inform about classroom exchanges. Video recordings are no exception. They facilitate the investigation of classroom interactions and the collection of audio-visual data that provide further insights into the teaching practice and classroom dynamics. Previous education research has almost turned a blind eye to uncovering the intricacies of elementary classroom behavior and interactions through the medium of modern technologies. Only scattered attempts have brought to bear the issue. To this end, this paper presents an overview of the salient role of digital technologies, mainly video materials, in clarifying the different interactions that take place within the confines of the classroom, including teacher-to-teaching assistant (TA) relationships, teacher-aide-to-pupil interactions, and peer-to-peer interaction drawing on an ongoing data collection from elementary schools around Hradec Králové (HK) region in the Czech Republic. Classroom recordings might be a fountainhead for detailed, reflective analysis, enhanced communication among all participants, and better teaching-learning practice if used properly. The first part of the paper reviews some related definitions based on several previous theoretical grounds. Then, it highlights the peculiar classroom interactions aided by various analytic angles. Deeply rooted in education research, these dynamics are indebted to the presence of audio and visual records. Most importantly, the paper is built around the research endeavor by researchers at the University of HK, mainly the Faculty of Education, that aims at getting down to brass tacks of TAs interactions by means of technological intervention in data collection (video recordings) and measurement (Flanders et al. – FIAS).

Published: June 2024

This study aimed to explore research trends in engineering education research through bibliometric analysis. This review comprised studies indexed in the Scopus database between 2014 and 2023. In total, 6,338 articles were examined using the bibliometric analysis method. The results revealed an increase in the number of publications in the research on engineering education from 2014 to 2023. The results also showed that most of the top-10 authors are from the USA and slight collaborations between research groups. The results also revealed that most institutions with the highest publications and citations are from the USA, a leading country in engineering education research, and only three are from other countries, Denmark, Spain, and Sweden. Also, we found that the top-three journals are the periodicals that publish articles specifically on engineering education. The results regarding research trends revealed the existence of research on participants’ self-efficacy beliefs, experiences, and perceptions and the effects of education technology practices on learning outcomes and teaching methods like project-based learning and problem-solving. Additionally, the research trends were found on design skills, decision-making, product design practices and professional development, technology integration practices, and teaching practices using artificial intelligence. Based on the results, we made implications for further studies.

Authors: Gondiawati Nani , Nurhayati Sri
Published: June 2024

This study examined the implementation of child-centered learning principles by the parents of TK Al Muthmainnah students, their knowledge of these principles, and the challenges they faced. A qualitative case study method was adopted, with ten parents participating as primary informants. Data were collected through observations, in-depth interviews, and document analysis, and were analyzed using a thematic analysis approach. The analysis revealed that parents possessed a foundational understanding of child-centered learning, viewing it as a way to foster autonomy and cater to their children's interests. They applied these principles at home by allowing children to make choices and encouraging exploration. However, they encountered challenges such as limited resources and the need for balancing guidance with children's independence. The findings suggest that while parents are inclined towards child-centered practices, the efficacy of these practices is affected by the availability of resources and support

Published: June 2024

The natural dynamics of the distribution of fish resources in marine waters are not uniform. This will have implications for optimizing the utilization of fish resources using various fishing gear in a fishing area. Fishing using millennium gillnets is generally not done by many fishermen on Ambon Island. The research aimed to determine the composition and influence of differences in millennium gillnet depth on catch results. This research method is a fishing experiment using 3 units of 3.5-inch millennium gillnets of uniform size which are set on the bottom of the water at treatment depths, namely 0-20 meters, 21-40 meters and > 40 meters. Simultaneous capture operations in the afternoon for 8 capture attempts. During the research, the catch was 364 fish weighing 209 kg. 6 types of fish were identified, namely Kuwe (Caranx sexfasciatus), yellow-tailed Lalosi (Caesio cunning), sand porter (Naso thynnoides), Samandar (Siganus sp), and grouper (Epinephelus merra), and mackerel (Scomberomorus gullatus). This type of fish is usually found swimming in open water or near the sea surface. The highest number of catches was the Kuwe fish species, 135 fish (37.09%) weighing 56.4 kg (26.99%), the lowest was the Tenggiri fish species (Scomberomorus gullatus), 5 fish (1.37%) weighing 5.1 kg (2, 44%). The highest catch was in the 21-40 m depth range, namely 162 fish and 94.7 kg, followed by more than 41 m, namely 103 fish and 57 kg, and the lowest in the 0-20 m depth range, namely 99 fish and 57.3 kg. The chance of catching fish occurs at all net-setting depths, but the highest chance occurs at 21-40 m. The results of the analysis showed that neither the overall catch nor the dominant fish species showed significant differences based on differences in depth.

Published: June 2024

Trust certification through so-called trust seals is a common strategy to help users ascertain the trustworthiness of a system. In this study, we examined trust seals for AI systems from two perspectives: (1) In a pre-registered online study participants, we asked whether trust seals can increase user trust in AI systems, and (2) qualitatively, we investigated what participants expect from such AI seals of trust. Our results indicate mixed support for the use of AI seals. While trust seals generally did not affect the participants’ trust, their trust in the AI system increased if they trusted the seal-issuing institution. Moreover, although participants understood verification seals the least, they desired verifications of the AI system the most.

Published: June 2024

The purpose of the study is to identify, based on the material of substantive vocabulary, the core of the nominative field of the concept of FRAUDSTER in the framework of modeling the cognitive structure of the situation of fraudulent interaction. The scientific novelty of the work lies in the fact that in it the phenomenon of fraud is studied for the first time in the aspect of its linguocognitive interpretation – as a conceptual field with a propositional structure. The article defines and analyzes for the first time the lexical and semantic paradigms of nominations of persons involved in a fraudulent act. As a result, a variety of substances objectifying the phenomenon of fraud has been revealed. The high productivity of the fraudster's designations by type of activity in the modern media space was noted. A wide range of multilevel linguistic units has been found, marking the "falsity", "imaginary" social status of a fraudster. The active updating of the composition of lexical and semantic groups under the influence of extralinguistic factors, in particular the processes of digitalization of modern society, has been revealed. For the first time, collocations reflecting the associative rapprochement of a fraudster with other offenders in the Russian language consciousness are analyzed. The high pragmatic potential of the substantives forming the nominative field of the concept of FRAUDSTER is substantiated.
Problem of the formation of a professional language style (based on Aviation English)
Authors: Lysenko Sergey Vladimirovich
Published: June 2024

The aim of the study is to demonstrate that the presence of an independent functional style of Aviation English indicates the existence of prerequisites for the formation of functional styles inherent in other professional languages, taking into account the peculiarities of their architectonics and the conditions in which they are used. The scientific novelty of the work lies in the fact that until now, the specific characteristics of the functional style of a professional language that make it an independent linguistic phenomenon have not been defined. The paper is the first to formulate the mandatory requirements for the architectonics of a professional language as a combination of its lexical, grammatical and phonetic systems used for communication by specialists in various fields and for the characteristic features of speech situations in a domain of professional activity. As a result, it is proven that only a fully formed architectonics of a particular professional language, allowing it to be used effectively in typical speech situations, makes it possible to determine whether this professional language has a full-fledged independent functional style.

Authors: Dzakhova Veronika Tambievna , Makarenko Mariya Dmitriyevna
Published: June 2024

The aim of the research is to identify all potential consonant clusters in the modern Ossetian literary language where assimilative and dissimilative changes are possible. The article discusses a detailed algorithm aimed at creating a theoretical basis for an orthoepic dictionary of the Ossetian literary language. The research is novel in that it is the first to obtain data on all possible assimilative and dissimilative processes in the Ossetian literary language. Consonant clusters were identified using a representative corpus of Ossetian texts presented on the Internet and consisting of 836,593 words. As a result of the study of 819 consonant clusters, such combinations were found in which, based on data on the phonemes of the Ossetian literary language, assimilative processes could be expected. In particular, this refers to consonant clusters where voiced and voiceless consonants meet at the boundaries of morphemes, voiced consonants in the final position and voiced consonants at the boundaries of morphemes. To determine the phonetic processes that occur in these clusters (progressive assimilation for voicing/devoicing, regressive assimilation for voicing/devoicing), words containing such clusters were included in the instrumental analysis program.

Published: June 2024

Decreased sexual desire is a type of sexual dysfunction that is common in men. Sexual dysfunction can be controlled by using herbs that have activity as aphrodisiacs. Many herbs are efficacious as aphrodisiacs, one of which is the icariin compound from the epimedium plant. However, the use of oral drugs must go through absorption and distribution processes to cause pharmacological effects, besides that the first pass effect that occurs in the liver reduces the bioavailability of the drug. This study aims to optimize the icariin nanohydrogel formula for use as a topical aphrodisiac, preparation characteristics, and the effect of nanohydrogel on the diffusion of icariin compounds. Formula optimization was carried out using the Simplex Latice Design (SLD) method with variations of carbopol, HPMC and TEA. Quantitative data analysis of aphrodisiac activity was analyzed by One Sample T-Test. The optimal formulation is obtained at a ratio of 1.415 (carbopol) : 2.168 (HPMC) : 1.208 (TEA), resulting in a clear, cucumber fish oil-scented preparation that is stable, with a viscosity of 19753.3 cps and an adhesive force of 0.387 seconds, pH 6.1, as well as a spreading power with a diameter of 5.56 cm. The hedonic test conducted on 4 formulas with the addition of fragrance shows that formula 3 is preferred by the respondents, followed by formula 4, formula 2, and formula 1. The cumulative amount of the penetrated preparation is 0,174 µg/cm2 at 10 minutes, 0,283 µg/cm2 at 15 minutes, 0,398 µg/cm2 at 30 minutes, 0,498 µg/cm2 at 60 minutes, and 0,603 µg/cm2 at 120 minutes.

Grankin (SE "GIPROKOKS'') The article is devoted to verification of ensuring the appropriate economy and efficiency of coke production while reducing the level of consumption of scarce raw materials in order to optimise production in the current conditions of a coke-chemical enterprise. It is shown that the production of blast furnace coke using the technology of tamping the coal charge allows the use of a large amount of cheap gas coal without reducing the quality of the resulting blast furnace coke. However, despite the fact that this coking technology has been in use for a long time, the literature data on the impact of increasing the loading density on coke quality parameters is insufficient, contradictory and outdated. This article describes the main technical solutions for the conversion of an existing coke oven battery from the bulk coking chamber loading technology to the tamped coal cake loading technology and presents the results for the reconstructed coke oven battery. This project was developed and implemented by SE “GIPROKOKS” and HuDe. The economic and technological indicators of coke quality as a result of the conversion of the existing coke oven battery to the technology of loading a tamped coal cake were considered and compared with the parameters of its operation using the technology of bulk loading of coking chambers. It is shown that during the control period of observations (19 months) of the enterprise's operation, the mechanical strength of M25 coke increased on average from 85.2 to 87.4 %; post-reaction strength CSR – from 48.9 to 53.9 %; at the same time, the abrasion index M10 decreased from 8.0 to 5.9 %, and the reactivity CRI – from 38.0 to 37.2 %, respectively, when working using the tamping technology compared to the bulk method. In addition, the coke obtained by using the charge tamping method is characterised by lower values of ash and total sulphur content.

Dancing with Change: A Conceptual Analysis of How Family Businesses Embrace Product Development Management
Authors: Tirdasari Nyayu Lathifah , Dhewanto Wawan , Arief Neneng Nurlaela
Published: June 2024

Understanding product development management is crucial, particularly within the context of family businesses, which are renowned for their resistance to change. Family firms demonstrate a paradox in innovation: while inclined toward calculated risk-taking, they often invest less in R&D compared with non-family businesses. This article explores the evolving landscape of product development management literature related to family businesses. It achieves this by meticulously examining pertinent scholarly works. Conducting a systematic review focused on family businesses’ product development management practices. This article poses the following fundamental question: What prior research has delved into the intersection of family businesses and product development management? The authors adopted the updated Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) reporting guidelines to ensure transparency and completeness in their systematic literature review. The research process hinges on accessing academic databases housing peer-reviewed journals, which initially yielded 955 articles. Through a series of discerning study selection phases, this number was pruned down to 68 articles eligible for further assessment. Ultimately, this study incorporates insights from 22 articles. Within the domain of product development management, the responsibility is typically divided among three key parties: marketing, design, and manufacturing. Notably, the findings underscore a predominant emphasis on the marketing perspective in the existing literature. Consequently, this article calls for future research endeavors to delve into the roles of design and manufacturing in the context of family business and product development management.

The history of pedagogical psychology is organically connected with educational, educational and pedagogical science. It is based on the development of social thought, the culture of the people, the achievements of science and especially general and age psychology. In all epochs, the teacher, the school, performing certain educational tasks, took into account the social, age, sexual characteristics of the physical and psychological development of the subject of education and upbringing-the child. It is in this understanding that the elements of pedagogical psychology are found in pedagogical practice and in various teachings of ancient times. It is worth mentioning the emergence of pedagogical psychologism in pedagogy, whose representatives considered it necessary to take into account the mental characteristics of students in the process of education and upbringing.

The outbreak of the coronavirus disease 2019 (COVID-19) led many individuals to utilize digital devices, including smartphones, to minimize in-person activities. Due to mixed results from previous studies, how the pandemic brought about a long-term impact on problematic smartphone use (PSU) is still unclear. This prospective study investigated whether levels of PSU increased over three years after the COVID-19 outbreak and afterward. Recruited through a research marketing company, 86,827 Japanese adults were eligible to take part in this study and responded to three outcome measures of PSU and other measures related to smartphone use and COVID-19. Data collection occurred before the outbreak in December 2019 and at six subsequent time points between the first outbreak in Japan and December 2022. Contrary to the hypothesis, growth model analysis revealed downward trajectories in all three PSU measures: the Smartphone Addiction Scale, Short Version, d = –0.13; smartphone overuse, d = –0.14; and negative consequences from overuse, d = –0.23. Complete case analysis suggested the robustness of these effect sizes. Moderators of the declines in all three PSU measures were higher PSU measures, namely spending less money on purchasing new apps and stronger beliefs about not having contracted COVID-19. The social cognitive theory may be particularly applicable to the findings such that digital technologies, including smartphones, may have been perceived as necessary preventive measures against the pandemic, resulting in lower perceptions of PSU.
Crime and Urban Politics
Authors: Alizade Jeyhun
Published: June 2024

Cities in advanced democracies are commonly portrayed as centers of cosmopolitanism and electoral strongholds of the left. I argue that the issue of crime can reshape urban politics by providing opportunities for right-wing parties as issue-owners of crime to make inroads among urban electorates, thereby weakening progressive parties' dominance over cities. Focusing on Germany, I first present evidence from a geocoded survey (N=3,083) showing that concern about crime is higher among both right- and left-wing voters in urban areas compared to their rural counterparts. A text analysis of a large corpus of political ads (N=35,359) posted on Facebook by German political parties and complemented with qualitative evidence further suggests that the center-right CDU/CSU strategically responds to voter concern about crime in cities, while left-wing parties pay little attention to this issue. In a final step, I demonstrate that the center-right's “urban strategy” pays off electorally: A neighborhood-level panel analysis of Berlin shows that crime increases the CDU's vote share in the state parliament elections, while decreasing electoral support for the Greens -- the party most closely associated with an urban, cosmopolitan electorate. On the micro-level, a candidate-choice conjoint experiment among German voters in large cities (N=2,086) demonstrates that the center-right can attract a substantial share of progressive voters from the Social Democrats and the Greens through law-and-order stances. Overall, this paper shows that the rightward shift of advanced democracies is not restricted to rural areas or small towns but extends to urban centers usually perceived to be progressive strongholds.

Published: June 2024

Traffic flow data has been used in various disciplines, including geography, transportation, urban planning, and public health. However, existing datasets often have limitations such as low spatiotemporal resolution and inconsistent quality due to data collection methods and the lack of adequate data cleaning process. This paper introduces a long-term traffic flow dataset at an intra-city scale with high spatio-temporal granularity. The dataset covers the Glasgow City Council area for four consecutive years spanning the COVID-19 pandemic, from October 2019 to September 2023, providing comprehensive temporal and spatial coverage. Such detailed information facilitates diverse applications, including traffic dynamic analysis, traffic management, infrastructure planning, and urban environment improvement. Also, it provides a valuable dataset to understand traffic flow change during a once-in-a-lifetime pandemic event.
Fracture criteria and tensile strength for natural glacier ice calibrated from remote sensing observations of Antarctic ice shelves

The conditions under which ice fractures and calves icebergs from Antarctic ice shelves are poorly understood due largely to a lack of relevant observations. Though previous studies have estimated the stresses at which ice fractures in the laboratory and through sparse observations, there remains significant uncertainty in the applicability of these results to naturally deforming glacier ice on larger scales. Here, we aim to better constrain the stresses under which ice fractures using remote sensing data by identifying large-scale fractures on Antarctic ice shelves, calculating the principal stresses from the observed strain rates, and comparing the stresses of unfractured and fractured areas. Using the inferred stresses, we evaluate five common fracture criteria: Mohr-Coulomb, von Mises, strain energy, Drucker-Prager, and Hayhurst. We find the tensile strength of ice ranges from 202 to 263 kPa assuming the viscous stress exponent n=3, narrowing the range produced by previous observational studies. For n=4, we find tensile strengths of 423-565 kPa, bringing our inferences closer to alignment with laboratory experiments. Importantly, we show that crevassed and uncrevassed areas in the four largest ice shelves are distinct in principal stress space, suggesting our results apply to all ice shelves and the broader ice sheet.
A tutorial on formalizing and testing specific psychological theory using nonlinear models
Authors: McCormick Ethan Michael
Published: June 2024

Nonlinear models represent exciting new opportunities for specifying and testing theory in ways that current linear models cannot. While linear models remain widespread and are relatively easy to estimate, the parameters of these models are often disconnected from specific psychological theories. Using nonlinear models, by contrast, allow us to test specific questions by linking model parameters to things we care about. Here, I will demonstrate promising uses of nonlinear models for formalizing and testing specific theory. First, I will show how we can use parameter moderation to model changes in the correlation between anxiety and depression within a nonlinear factor model. Then I showcase three examples in the regression and growth modeling space, demonstrating how nonlinear models can capture features of change, such as peaks and nonlinear transitions, that are not readily-available in linear models. Throughout, I use beginner-friendly language when discussing these topics and provide freely-available code resources for helping to specify and fit all models discussed. Readers will take away both a broad theoretical understanding of how nonlinear alternatives can better match statistical with theoretical models and offer specific hypothesis tests in psychology, as well as the practical skills for implementing the wide array of approaches within their own research domain.
Związek między miłością, ilością dzieci a jakością życia
Authors: Błaszczyk Małgorzata
Published: June 2024

Miłość jest uniwersalnym uczuciem, które kształtuje nasze relacje międzyludzkie i ma znaczący wpływ na jakość naszego życia. Trójkątna teoria miłości Sternberga, składająca się z intymności, namiętności i zaangażowania, oferuje kompleksowe zrozumienie struktury miłości. Badania nad miłością często koncentrują się na jej wpływie na różne aspekty życia, w tym na liczbę posiadanych dzieci i ogólną jakość życia. W niniejszym badaniu przeanalizowano korelacje między komponentami miłości według Sternberga, liczbą dzieci a jakością życia, używając trójwymiarowej skali miłości Sternberga oraz testu na jakość życia WHO-5. Wyniki pokazują, że namiętność jest jedynym składnikiem miłości, który koreluje zarówno z jakością życia, jak i liczbą dzieci. Tu pokazuje, że namiętność ma znaczący wpływ na jakość życia oraz liczbę posiadanych dzieci. Wcześniejsze badania sugerowały, że miłość może wpływać na różne aspekty życia, ale moje badanie szczegółowo wykazało, że to namiętność, a nie intymność czy zaangażowanie, jest kluczowa. To odkrycie wzbogaca wcześniejszą wiedzę, podkreślając rolę namiętności w poprawie jakości życia i zwiększeniu liczby dzieci. Moje wyniki sugerują, że interwencje mające na celu zwiększenie namiętności w związkach mogą mieć pozytywny wpływ na jakość życia i decyzje reprodukcyjne. W szerszym kontekście, zrozumienie tych dynamik może pomóc w tworzeniu programów wsparcia dla par, aby poprawić ich dobrostan psychologiczny i środowiskowy.
Possessing Potential Weapons (Still) Heightens Anger Perception: Replicating and Extending a Test of Error Management Theory
Authors: Holbrook Colin , Moser Cody James , Ellks Richard , Jones Ayonna
Published: June 2024

Error Management Theory (EMT) hypothesizes that humans are functionally biased to err on the side of the least costly mistake when making judgments under uncertainty. Applying EMT to emotion perception, previous studies found that people perceive individuals holding everyday objects with potentially lethal affordances to be both higher in state anger and more anger-prone, relative to individuals holding control objects. Here, we aim to replicate these effects and to exploratorily test whether friends of an individual possessing a potentially lethal tool are also perceived as angrier – and hence more dangerous – in a “reverse-halo” effect. Participants (N = 476) were presented an image of an individual depicted as an avid cook and either holding or near a conventional kitchen knife, then asked to rate their emotional states and trait dispositions. Participants were next presented with an image of a second individual framed as a close friend of the cooking enthusiast and asked to assess their emotional states and dispositions. The results replicated prior findings that individuals depicted holding everyday objects with incidentally lethal affordances are perceived as angrier, more prone to anger, and more socially unpleasant. However, we did not find evidence for a “reverse-halo” effect extending to friends. Instead, all of the state and trait emotion ratings of the two individuals were significantly correlated, consistent with an inference (orthogonal to error management motivations) of homophilic similarity in the affective profiles of friends. These results are discussed as they inform prior EMT research and motivate further study of the determinants of emotion perception.
The influence of self-experienced Iconic finger-postures on Numerical processing: Hemispheric asymmetries in semantic integration.
Authors: Adriano Andrea
Published: June 2024

Main theories of embodied cognition assume that arbitrary abstract concepts (e.g., words, numbers) are understood through their grounding in our sensory-motor system. Recent evidence shows that performing iconic finger embodied gestures (finger-montring) primes number processing, suggesting a shared numerical semantic representation between Arabic and finger-numeral representations. However, it is still unknown in which hemisphere this cross-talk could happen. To investigate where the cross-modal semantic priming between self-experienced iconic finger-postures and visual Arabic digit processing would occur in the brain, we tested educated adults in a simple numerical identification task with lateralized stimuli, while they covertly executed task-irrelevant finger-montring configurations. Participants were instructed to identify a set of Arabic digits (2-3-4) presented in each hemisphere by Divided Visual Field (DVF) paradigm responding with one hand, while the non-responding hand was fixed in canonical (iconic) or non-canonical (non-iconic) finger-posture. Results showed that RTs for Arabic digit (e.g., 3) identification were faster in left hemisphere, particularly when participants’ non-responding hand was fixed in canonical configuration compared to non-canonical configuration, but only when both bodily-hand information and visual stimuli were matched simultaneously within the left hemisphere. On the other hand, no semantic priming was found when both stimuli (body and visual) were matched in the right hemisphere. These results suggest that own proprioceptive perception of finger-numeral postures primes symbolic number processing in left hemisphere but not in the right, at least for small numbers. Taken together, we illustrate a clear hemispheric asymmetry in the semantic integration between iconic finger-numeral and Arabic-digit representations.
