RESUMEN

Introduction: This study aimed to explore the arousal and valence that people experience in response to Hangul phonemes based on the gender of an AI speaker through comparison with Korean and Chinese cultures. Methods: To achieve this, 42 Hangul phonemes were used, in a combination of three Korean vowels and 14 Korean consonants, to explore cultural differences in arousal, valence, and the six foundational emotions based on the gender of an AI speaker. A total 136 Korean and Chinese women were recruited and randomly assigned to one of two conditions based on voice gender (man or woman). Results and discussion: This study revealed significant differences in arousal levels between Korean and Chinese women when exposed to male voices. Specifically, Chinese women exhibited clear differences in emotional perceptions of male and female voices in response to voiced consonants. These results confirm that arousal and valence may differ with articulation types and vowels due to cultural differences and that voice gender can affect perceived emotions. This principle can be used as evidence for sound symbolism and has practical implications for voice gender and branding in AI applications.

RESUMEN

Low detectability and camouflage skills in the electromagnetic wave and light frequency range provide survival advantages for natural creatures and are essential for understanding the operational principles of the biosphere. Taking inspiration from natural mutualistic symbiosis, this paper proposes a symbiotic electromagnetic shadow camouflage mechanism based on a superdispersive surface, aiming to investigate its impact on the observability of specific objects. The design and experimental results indicate that the symbiotic shadow dihedral can significantly reduce overall scattering quantity, which reaches at least 10 dB shrink in the 12-18 GHz frequency range compared to the contrast object. Unlike known camouflage methods, the electromagnetic shadow technology shrinks the overall scattering without any coating and shield metal target while probably offering extensive functional design freedom for the concealed object, creature, or equipment. This also provides a hint to explore symbiosis-related camouflage phenomena in nature.

RESUMEN

The notion of sound symbolism receives increasing interest in psycholinguistics. Recent research - including empirical effects of affective phonological iconicity on language processing (Adelman et al., 2018; Conrad et al., 2022) - suggested language codes affective meaning at a basic phonological level using specific phonemes as sublexical markers of emotion. Here, in a series of 8 rating-experiments, we investigate the sensitivity of language users to assumed affectively-iconic systematic distribution patterns of phonemes across the German vocabulary:After computing sublexical-affective-values (SAV) concerning valence and arousal for the entire German phoneme inventory according to occurrences of syllabic onsets, nuclei and codas in a large-scale affective normative lexical database, we constructed pseudoword material differing in SAV to test for subjective affective impressions.Results support affective iconicity as affective ratings mirrored sound-to-meaning correspondences in the lexical database. Varying SAV of otherwise semantically meaningless pseudowords altered affective impressions: Higher arousal was consistently assigned to pseudowords made of syllabic constituents more often used in high-arousal words - contrasted by less straightforward effects of valence SAV. Further disentangling specific differential effects of the two highly-related affective dimensions valence and arousal, our data clearly suggest arousal, rather than valence, as the relevant dimension driving affective iconicity effects.

RESUMEN

A number of studies have provided evidence of limited non-arbitrary associations between the phonological forms and meanings of affective words, a finding referred to as affective sound symbolism. Here, we explored whether the affective connotations of Spanish words might have more extensive statistical relationships with phonological/phonetic features, or affective form typicality. After eliminating words with poor affective rating agreement and morphophonological redundancies (e.g., negating prefixes), we found evidence of significant form typicality for emotional valence, emotionality, and arousal in a large sample of monosyllabic and polysyllabic words. These affective form-meaning mappings remained significant even when controlling for a range of lexico-semantic variables. We show that affective variables and their corresponding form typicality measures are able to significantly predict lexical decision performance using a megastudy dataset. Overall, our findings provide new evidence that affective form typicality is a statistical property of the Spanish lexicon.

RESUMEN

The alchemical concepts of chemical symbolism, nomenclature, and affinity underwent fundamental changes between the 1770s and the 1820s, roughly simultaneously with the Chemical Revolution (ca. 1772-89), i. e. the replacement of the phlogiston theory with Lavoisier's New Chemistry. Using the old, alchemical symbols, Bergman devised a system of formulas to describe virtually all known inorganic chemistry, and he influenced Guiton de Morveau's Mémoire sur les Dénominations Chimiques, and the subsequent Méthode de nomenclature. Hassenfratz and Adet devised a new artificial sign language which, however, was too complicated and unintuitive to gain widespread acceptance. Bergman refined the concept of affinity, but his belief in phlogiston rapidly made the system obsolete. Wenzel realized that the dissolution of metals in acids is not just a question of affinity but rather of concentration, and he and Berthollet separately formulated early versions of the Law of Mass Action thereby making attempts to quantify affinity redundant. Richter formulated a principle that became known as the Law of Equivalent Proportions, describing acid-base reactions and double decompositions of salts, but continuing to use Bergman-style alchemical formulas. Only John Dalton's atomic theory with little globules denoting atoms and their combination into molecules made a definite break with the alchemical symbols.

RESUMEN

It has been shown that reading the vowel [i] and consonant [t] facilitates precision grip responses, while [ɑ] and [k] are associated with faster power grip responses. A similar effect has been observed when participants perform responses with small or large response keys. The present study investigated whether the vowels and consonants could produce different effects with the grip responses and keypresses when the speech units are read aloud (Experiment 1) or silently (Experiment 2). As a second objective, the study investigated whether the recently observed effect, in which the upper position of a visual stimulus is associated with faster vocalizations of the high vowel and the lower position is associated with the low vowel, can be observed in manual responses linking, for example, the [i] with responses of the upper key and [ɑ] with lower responses. Firstly, the study showed that when the consonants are overtly articulated, the interaction effect can be observed only with the grip responses, while the vowel production was shown to systematically influence small/large keypresses, as well as precision/power grip responses. Secondly, the vowel [i] and consonant [t] were associated with the upper responses, while [ɑ] and [k] were associated with the lower responses, particularly in the overt articulation task. The paper delves into the potential sound-symbolic implications of these phonetic elements, suggesting that their acoustic and articulatory characteristics might implicitly align them with specific response magnitudes, vertical positions, and grip types.

RESUMEN

The aim of the study is to analyse contemporary postmodern literary works of Kazakhstan through the conceptual prism of Freudian and Jungian psychoanalysis. To achieve research goals, the following methods were used: axiomatic, content analysis, and comparative. The results of the study determined that contemporary Kazakh writers characterise a large field of motives and ideas that are revealed through text, symbols, and characters. Strong tools for their interpretation were the psychological approaches of Freud and Jung, which are the standards of psychoanalysis and have their own specific features of semantic content. Content analysis of postmodern materials has established that Kazakh stories trace the motives of mythology, religion, relationships and inner spiritual development, which consider the mental differences of the heroes of the storylines. During the psychoanalysis of the works, it was emphasised that postmodernism in the literature of Kazakhstan reflects the rejection of absolute truths, blurring the boundaries between genres, playing with traditional forms and content. Many of the characters in the stories are experiencing an identity crisis, which has been analysed through the Freudian triad and Jung's archetypal images. Kazakh literature, being woven into the cultural and historical heritage of the nation, reflects the features of mentality, socio-cultural transformations, identity and spiritual quest of heroes.

RESUMEN

Sound symbolism refers to non-arbitrary associations between word forms and meaning, such as those observed for some properties of sounds and size or shape. Recent evidence suggests that these connections extend to emotional concepts. Here we investigated two types of non-arbitrary relationships. Study 1 examined whether iconicity scores (i.e. resemblance-based mapping between aspects of a word's form and its meaning) for words can be predicted from ratings in the affective dimensions of valence and arousal and/or the discrete emotions of happiness, anger, fear, disgust and sadness. Words denoting negative concepts were more likely to have more iconic word forms. Study 2 explored whether statistical regularities in single phonemes (i.e. systematicity) predicted ratings in affective dimensions and/or discrete emotions. Voiceless (/p/, /t/) and voiced plosives (/b/, /d/, /g/) were related to high arousing words, whereas high arousing negative words tended to include fricatives (/s/, /z/). Hissing consonants were also more likely to occur in words denoting all negative discrete emotions. Additionally, words conveying certain discrete emotions included specific phonemes. Overall, our data suggest that emotional features might explain variations in iconicity and provide new insight about phonemic patterns showing sound symbolic associations with the affective properties of words.

RESUMEN

This study investigates the extent to which gender can be inferred from the phonemes that make up given names and words in American English. Two extreme gradient boosted algorithms were constructed to classify words according to gender, one using a list of the most common given names (N∼1,000) in North America and the other using the Glasgow Norms (N∼5,500), a corpus consisting of nouns, verbs, adjectives, and adverbs which have each been assigned a psycholinguistic score of how they are associated with male or female behaviour. Both models report significant findings, but the model constructed using given names achieves a greater accuracy despite being trained on a smaller dataset suggesting that gender is expressed more robustly in given names than in other word classes. Feature importance was examined to determine which features were contributing to the decision-making process. Feature importance scores revealed a general pattern across both models, but also show that not all word classes express gender the same way. Finally, the models were reconstructed and tested on the opposite dataset to determine whether they were useful in classifying opposite samples. The results showed that the models were not as accurate when classifying opposite samples, suggesting that they are more suited to classifying words of the same class.

RESUMEN

The authors take inspiration from a case of hysterical psychosis to illustrate a typical condition of this evocative disease: the symbolic language of hysteria, conjurer of archetypical images. The authors encourage the clinician not to decode such aspects in rational analytical terms, rather to have a more wide-open approach that promotes the emergence of the individual unconscious, reconnecting with the collective imagination. This approach could help psychiatrists better understand a subject's inner experiences and interpersonal behavior. (AU)

RESUMEN

Iconic words and signs are characterized by a perceived resemblance between aspects of their form and aspects of their meaning. For example, in English, iconic words include peep and crash, which mimic the sounds they denote, and wiggle and zigzag, which mimic motion. As a semiotic property of words and signs, iconicity has been demonstrated to play a role in word learning, language processing, and language evolution. This paper presents the results of a large-scale norming study for more than 14,000 English words conducted with over 1400 American English speakers. We demonstrate the utility of these ratings by replicating a number of existing findings showing that iconicity ratings are related to age of acquisition, sensory modality, semantic neighborhood density, structural markedness, and playfulness. We discuss possible use cases and limitations of the rating dataset, which is made publicly available.

RESUMEN

It has been suggested that actions can provide a fruitful conceptual context for sound symbolism phenomena, and that tight interaction between manual and articulatory processes might cause that hand actions, in particular, are sound-symbolically associated with specific speech sounds. Experiment 1 investigated whether novel words, built from speech sounds that have been previously linked to precision or power grasp responses, are implicitly associated with perceived actions that present precision manipulation or whole-hand grasp tool-use or the corresponding utilisation pantomimes. In the two-alternative forced-choice task, the participants were more likely to match novel words to tool-use actions and corresponding pantomimes that were sound-symbolically congruent with the words. Experiment 2 showed that the same or even larger sound-action symbolism effect can be observed when the pantomimes present unfamiliar utilisation actions. Based on this we propose that the sound-action symbolism might originate from the same sensorimotor mechanisms that process the meaning of iconic gestural signs. The study presents a novel sound-action phenomenon and supports the view that hand-mouth interaction might manifest itself by associating specific speech sounds with grasp-related utilisations.

RESUMEN

The art of the Achaemenid Empire flourished in Ancient Persia from the 6th to 4th centuries BCE, and featured stone-carved monumental structures adorned with recurring zoological and floral patterns. Such representations clearly had a symbolic meaning intimately connected to religious expression and the will of deities. Considering the lack of any comprehensive analysis of botanical features, we investigate the recurring plant patterns and the variety of plants depicted. An analysis of the documentation referring mainly to monuments in the two main capitals of Darius I, Persepolis and Susa, showed the presence of certain repetitive elements, such as the so-called rosettes (composed variously of Asteraceae capitula and Nymphaea flowers), palms (Phoenix dactylifera, the tree of life), pines, flowers or bunches and metamorphic elements. Some plants are described in this paper for the first time in the context of Persian iconography, such as Mandragora officinalis in offering scenes as a symbol of fertility and protection against evil spirits, Pinus brutia var. eldarica as a symbol of immortality and elevation to the gods, and the capitula of Matricaria/Leucanthemum as solar symbols. Further interesting elements include cf. Myrtus communis in some crowns and probably cf. Ephedra sp. in offering scenes. Achaemenid art was deeply influenced by the Zoroastrian religion of ancient Persia with its great attention to nature as well as by the nearby civilizations of the Mesopotamian area and Egypt. Most elements were also associated with psychotropic or medicinal attributes, which contributed to their position as symbols of power.

RESUMEN

Previous investigations have shown various interactions between spatial concepts and speech sounds. For instance, the front-high vowel [i] is associated with the concept of forward, and the back-high vowel [o] is associated with the concept of backward. Three experiments investigated whether the concepts of forward/front and backward/back are associated with high- and low-pitched vocalizations, respectively, in Finnish. In Experiments 1 and 2, the participants associated the high-pitched vocalization with the forward-directed movement and the low-pitched vocalizations with the backward-directed movement. In Experiment 3, the same effect was observed in relation to the concepts of front of and back of. We propose that these observations present a novel sound-space symbolism phenomenon in which spatial concepts of forward/front and backward/back are iconically associated with high- and low-pitched speech sounds. This observation is discussed in relation to the grounding of semantic knowledge of these spatial concepts in the movements of articulators such as relative front/back-directed movements of the tongue.

RESUMEN

This narrative review presents a comprehensive examination of artistic periods since the Renaissance, paralleling the evolution of neurology and pictorial artistic expression about sleep, ending with the importance of the contemporary digital era. Over the centuries, artists have been drawn to the enigmatic themes of dreams, sleep, and their disorders, using them to explore the complexities of the human condition, emotions, and the interaction between reality and imagination. Thus, drawing references from diverse artistic eras, including their pictorial representations of sleep, alongside milestones in the history of neurology, this study reveals a rich interconnectivity between art, neurological advances, and social change.

Assim, extraindo referências de diversas épocas artísticas, incluindo suas representações pictóricas do sono, paralelamente a marcos na história da neurologia, este estudo revela uma rica interconectividade entre arte, avanços neurológicos e mudanças sociais.

RESUMEN

Iconicity refers to a resemblance between word form and meaning. Previous work has shown that iconic words are learned earlier and processed faster. Here, we examined whether iconic words are recognized better on a recognition memory task. We also manipulated the level at which items were encoded-with a focus on either their meaning or their form-in order to gain insight into the mechanism by which iconicity would affect memory. In comparison with non-iconic words, iconic words were associated with a higher false alarm rate, a lower d' score, and a lower response criterion in Experiment 1. We did not observe any interaction between iconicity and encoding condition. To test the generalizability of these findings, we examined effects of iconicity in a recognition memory megastudy across 3880 items. After controlling for a variety of lexical and semantic variables, iconicity was predictive of more hits and false alarms, and a lower response criterion in this dataset. In Experiment 2, we examined whether these effects were due to increased feelings of familiarity for iconic items by including a familiar versus recollect decision. This experiment replicated the overall results of Experiment 1 and found that participants were more likely to categorize words that they had seen before as familiar (vs. recollected) if they were iconic. Together, these results demonstrate that iconicity has an effect on memory. We discuss implications for theories of iconicity.

RESUMEN

Constructed languages, frequently invented to support world-building in fantasy and science fiction genres, are often intended to sound similar to the characteristics of the people who speak them. The aims of this study are (1) to investigate whether some fictional languages, such as Orkish whose speakers are portrayed as villainous, are rated more negatively by listeners than, for example, the Elvish languages, even when they are all produced without emotional involvement in the voice; and (2) to investigate whether the rating results can be related to the sound structure of the languages under investigation. An online rating experiment with three 7-point semantic differential scales was conducted, in which three sentences from each of 12 fictional languages (Neo-Orkish, Quenya, Sindarin, Khuzdul, Adûnaic, Klingon, Vulcan, Atlantean, Dothraki, Na'vi, Kesh, ʕuiʕuid) were rated, spoken by a female and a male speaker. The results from 129 participants indicate that Klingon and Dothraki do indeed sound more unpleasant, evil, and aggressive than the Elvish languages Sindarin and Quenya. Furthermore, this difference in rating is predicted by certain characteristics of the sound structure, such as the percentage of non-German sounds and the percentage of voicing. The implications of these results are discussed in relation to theories of language attitude.

RESUMEN

This study focuses on the importance of the symbolism of social control by the woman as the Varayoc (an office of authority of Incan origin) in a community in the Peruvian Andes. The objective is to explain the survival of the office of the Varayoc-traditionally held exclusively by men-and the acceptance of Andean women to it as a recognition of gender equality. In this field investigation, we interviewed and observed the most important activities of a woman Varayoc administering justice and present in all communal tasks. We conclude that women in the Peruvian Andes are approaching a status of equality with men in their position as the Varayoc, while maintaining the Incan tradition of local governance through the symbolism of the rod of command, which is also called Varayoc. It is evident that more women in the Andean community are interested in assuming political leadership with the symbolism of the ancestral Varayoc.

RESUMEN

Introduction: Sound symbolism is the phenomenon of sounds having non-arbitrary meaning, and it has been demonstrated that pseudowords with sound symbolic elements have similar meaning to lexical words. It is unclear how the impression given by the sound symbolic elements is semantically processed, in contrast to lexical words with definite meanings. In event-related potential (ERP) studies, phonological mapping negativity (PMN) and N400 are often used as measures of phonological and semantic processing, respectively. Therefore, in this study, we analyze PMN and N400 to clarify the differences between existing sound symbolic words (onomatopoeia or ideophones) and pseudowords in terms of semantic and phonological processing. Methods: An existing sound symbolic word and pseudowords were presented as an auditory stimulus in combination with a picture of an event, and PMN and N400 were measured while the subjects determined whether the sound stimuli and pictures match or mismatch. Results: In both the existing word and pseudoword tasks, the amplitude of PMN and N400 increased when the picture of an event and the speech sound did not match. Additionally, compared to the existing words, the pseudowords elicited a greater amplitude for PMN and N400. In addition, PMN latency was delayed in the mismatch condition relative to the match condition for both existing sound symbolic words and pseudowords. Discussion: We concluded that established sound symbolic words and sound symbolic pseudowords undergo similar semantic processing. This finding suggests that sound symbolism pseudowords are not judged on a simple impression level (e.g., spiky/round) or activated by other words with similar spellings (phonological structures) in the lexicon, but are judged on a similar contextual basis as actual words.

RESUMEN

It has long been a tradition for doctors to dress professionally in white coats - a universal symbol of belonging to the medical profession. This tradition dates back to the time of Hippocrates, but during the XIX-XXI centuries, the symbolism of the white coat was criticized in connection with research on the spread of infections through tissue. Currently, many doctors refuse to use the oldest symbol of the profession, and the practice of medical activity is replete with new variants of the uniform of a medical worker (both in style and in color palette. However, it should be noted that the white coat symbolizes another important part of the medical education of students, the standard of professionalism and care, as well as a symbol of the trust they must earn from patients.
