HUMAN INTERACTION AND EMOTIONAL POLYMORPHISM

Objective: The objective of this study is to explore the behavior of emotional polymorphism in individuals through the execution of basic tasks. Theoretical Framework: It was found that individuals exhibit various components or variants of emotions within an emotional state, influenced by various external factors classified as general and task-specific. In the first case, the emotional state was composed of Contextual Emotions (EmC), and in the second by Induced Emotions (EmI). Nevertheless, each state comprised a variety of emotional components, even with different valences reported by self-reporting individuals, which was termed Emotional Polymorphism (PEm). Method: A controlled experiment was designed where participants performed two basic tasks using controlled time work systems and perception. Additionally, semi-structured interviews were conducted through self-reporting, where participants were asked for statistical data as well as a description of their emotional valence. Results and Discussion: The results obtained revealed that there are variations in the emotional components (CEm) that make up each emotional polymorphism, considering an initial state comprised of EmC and a final response made up of EmI. Implications of the Research: Managing error through the study of the components that may amplify it can assist in improving the design of interfaces and work systems that are important in the daily lives of users, such as ATMs. Originality/Value: This study contributes to the literature by exploring the behavior of the components of Emotional states, as a result of contextual factors and specific tasks.

„Das Kind hat mehr Zeit als wir.“ Zeitwahrnehmung bei Kindern und Erwachsenen in Michael Endes Momo

The concepts of time and time perception are crucial in this article. Moreover, the fact that time is perceived differently from children to adults is exemplified through theory and practice. The main object of analysis is the cult classic fantasy novel Momo by Michael Ende. Published in 1973, the book emphasizes the fact that children and adults have different visions and different usage of time. While children seem to have time in abundance, focusing on play and fun ways to spend it, adults fear they don’t have enough time on their hands. Michael Ende proposes a possible worlds dystopic scenario in which relentless and cunning so-called time-thieves have power over human time. It is only little Momo with her unique, effortless approach to temporality that can save humankind from extinction. Counting on his readership being entertained by his book, Michael Ende’s novel also has the power to make us highly aware of the consequences of poor time management. For this reason, the following article also ponders over the moralizing aspects of this timeless novel.

“Working is my me time”: Exploring the perception of me time among working mothers

Me time holds significance for personal enjoyment and relaxation, yet its exploration, particularly among Indonesian mothers, is limited. This qualitative study interviewed three full-time working mothers (aged 28, 30 and 36) to understand their perceptions in me time allocation before marriage, after marriage, and after having children. Thematic analysis identified six major themes: a) the importance of me time, b) factors hindering it, c) diverse interpretations, d) activities pursued, e) repercussions of inadequate me time, and f) coping strategies employed. This study underscores the significance of dedicating me time as a means to alleviate the stress experienced in day-to-day life. Maternal individuals exhibit an adaptive inclination to tailor their approach to personal time management in light of the demands imposed by motherhood. This research effectively accentuates the necessity of prioritizing me time to enhance holistic well-being and fortitude when confronted with maternal responsibilities.

Negative Emotion (dys)regulation Predicts Distorted Time Perception: Preliminary Experimental Evidence and Implications for Psychopathology.

Accurate time perception is crucial to daily life but vulnerable to interference, particularly through negative affect, which dilates individuals' sense of time passing. Regulation strategies like rumination, and disorders like borderline personality disorder (BPD), are linked to time distortion, yet their interrelationships remain untested. We investigated whether rumination and BPD symptoms increase time dilation in negative affective states to understand the clinical implications of time distortion. In an online pilot study, we tested whether negative affect (NA) predicts subjective time perception and explored how rumination, BPD symptoms, and their interaction predicted time perception using a between-subjects online experimental mood induction. Adult participants (Ncombined = 760) were recruited from Prolific Academic and a large, Midwestern U.S. university. State NA and increased BPD features predicted increased time dilation. The role of trait-level rumination was nuanced, with individuals low in BPD symptoms and elevated trait rumination exhibiting reduced time dilation in response to NA. Conversely, those with elevated rumination and BPD symptoms reported increased time dilation in the neutral condition. Findings offer foundational evidence of NA and rumination's roles in time dilation for individuals across levels of BPD symptom endorsement. Subsequent replication and extension could flesh out these relationships and inform psychotherapeutic treatment targets.

Time perception and delay discounting in the FMR1 knockout rat.

There is substantial evidence for timing (time perception) abnormalities related to developmental disabilities, particularly autism spectrum disorder. These findings have been reported in humans and nonhuman preclinical models. Our research objective was to extend that work to a genetic knockout (KO) model of fragile X/developmental disability, the FMR1KO rat. We also sought to test delay discounting in the model and assess potential relations between timing and choice behavior. Consistent with previous human and nonhuman work, we found reduced timing precision in the FMR1 KO rats. We also discovered significantly increased smaller, sooner reward choice in the FMR1 KO rats. Performance on the timing task appeared to be unrelated to performance on the choice task for both model and control rats. These results add to what has become increasingly clear: timing is disrupted in humans diagnosed with developmental disabilities and in nonhuman models designed to model developmental disabilities. Our findings are consistent with those of previous work and the first to our knowledge to show such effects in the FMR1 KO rat. We discuss the potential clinical implications and future directions surrounding potential "timing interventions" for individuals diagnosed with developmental disabilities.

Identification of key narratives to assess students’ perception of social reality

Introduction. The article presents the results of the research investigation on identifying key narratives in the perception of the external social environment by university students on the example of St. Petersburg Peter the Great Polytechnic University (hereinafter referred to as SPbPU). The aim of the article is to identify key narratives (images of the present, past, and future) to assess students’ perception of social reality, to substantiate key needs of students in the field of soft skills development and to summarize the practices in the field of teaching these skills in SPbPU. Materials and Methods. The key methods of obtaining research data include the survey, participant observation of the research team members within the framework of professional activities, analysis of documents on the issues of teaching and assessment of teaching Soft Skills disciplines. The methods of semantic analysis, generalization, comparison, data visualization, and verification were used in order to collect data, process and present them. Results. The authors identified key narratives in the perception of the external social environment by university students, including peculiarities of the perception of enlarged groups in social, humanitarian and technical fields of study. The data on the key needs of young people within the framework of Soft Skills acquisition and the experience of implementing such disciplines on the example of SPbPU were generalized. During the study, a search semantic analysis of existing evaluative acronyms was applied to investigate the existing image of reality perception in the target group, and the DICE acronym was introduced to summarize the desired image of the future in university students. The practical results of the research consist in the possibilities to assess the potential of practices in the disciplines within the framework of «Soft Skills» in SPbPU and modernization of similar practices in other universities. Conclusions. The article concludes about the need to build an effective feedback system with university students, which will allow, based on specialized Soft Skills practices, to respond flexibly to needs in the field of deficit skills and competencies of students and ensure their acquisition. In addition, the importance of identifying the existing narratives in the youth environment in the field of perception of social environment and social time to realize the educational, communicative and moral functions of higher education institutions is shown.

Ultrasound-Guided Axillary Access Using a Micropuncture Needle Versus Conventional Cephalic Venous Access for Implantation of Cardiac Devices: A Single-Center Randomized Trial

(1) Background: Ultrasound-guided axillary (USAX) vein puncture is a relatively new method to obtain venous access for the implantation of cardiac implantable electronic devices (CIED). However, its use is limited as most of the operators are not familiar with this technique. Our aim was to investigate the safety and efficacy of the USAX compared with the traditional cephalic vein dissection for venous access in CIED implantation. (2) Methods: This was a single-center, randomized, controlled, superiority trial. A total of 114 patients were randomized (1:1 ratio) to either USAX (u/s axillary group; 59 patients) or cephalic vein access (cephalic group; 55 patients). The primary study endpoint was defined as successful placement of all leads via the chosen access. Secondary study endpoints included time from local anesthetic injection to lead advancement in the SVC, total procedure time (skin to skin), procedure-related complications and pain perception. (3) Results: USAX was superior to cephalic access in terms of primary endpoint (OR: 4.3, 95% CI: 1.3, 14.0; p = 0.012). Total procedure duration was higher in the cephalic group (55.15 ± 16.62 vs. 48.35 ± 12.81 min, p = 0.017) but there was neither a significant difference in fluoroscopy time (p = 0.872) nor in total radiation dose (p = 0.815). The level of pain was higher in the cephalic group (p = 0.016), while the rates of complications were similar in both groups (p > 0.05). (4) Conclusion: USAX was superior to cephalic access regarding success rate, total procedure duration and level of pain, while having no difference in complication rates.

The TIME, SPACE, and GESTURE in a crossdisciplinary context

In any performance genre, the use of time is a fundamental element that shapes the artistic experience. When artists from different disciplines come together to collaborate on the same material, the perception and utilization of time as an artistic device can undergo significant transformations. This exposition delves into the intricate realm of non-verbal artistic communication between performers from diverse disciplines, with a specific focus on how the actions of one artist can profoundly influence and shape the decisions of another. To explore this dynamic interplay, a compelling case study is presented, examining the enchanting character miniatures for solo piano composed by Alexander Scriabin during the middle and late periods of his life. These exquisite musical pieces are interwoven with the fluidity and spontaneity of contemporary dance improvisation, creating a rich tapestry of artistic expression. Within this crossdisciplinary collaboration, the exposition sheds light on the ephemeral layers of communication that exist between performers. It delves into thought-provoking topics such as the sense of flow, movement, and structure within the work, the role of physical distance between performers and its intricate relationship with the passage of time, the density of content (i.e., musical material) in the context of crossdisciplinary exploration, and the profound significance of gestural communication between artists. Through this crosspollination of ideas and artistic exchange, the potential for profound and transformative artistic impact emerges. In essence, this exposition offers a thought-provoking exploration of the transcendent power of artistic communication between performers from different disciplines.

Fluid deresuscitation in critically ill children: comparing perspectives of intensivists and nephrologists.

Fluid accumulation, presently defined as a pathologic state of overhydration/volume overload associated with clinical impact, is common and associated with worse outcomes. At times, deresuscitation, the active removal of fluid via diuretics or ultrafiltration, is necessary. There is no consensus regarding deresuscitation in children admitted to the pediatric intensive care unit. Little is known regarding perceptions and practices among pediatric intensivists and nephrologists regarding fluid provision and deresuscitation. Cross-sectional electronic survey of pediatric nephrologists and intensivists from academic societies in the United States designed to better understand fluid management between disciplines. A clinical vignette was used to characterize the perceptions of optimal timing and method of deresuscitation initiation at four timepoints that correspond to different stages of shock. In total, 179 respondents (140 intensivists, 39 nephrologists) completed the survey. Most 75.4% (135/179) providers believe discussing fluid balance and initiating fluid deresuscitation in pediatric intensive care unit (PICU) patients is "very important". The first clinical vignette time point (corresponding to resuscitation phase of early shock) had the most dissimilarity between intensivists and nephrologists (p = 0.01) with regards to initiation of deresuscitation. However, providers demonstrated increasing agreement in their responses to initiate deresuscitation as the clinical vignette progressed. Compared to intensivists, nephrologists were more likely to choose "dialysis or ultrafiltration" as a deresuscitation method during the optimization [10.3 vs. 2.9% (p = 0.07)], stabilization [18.0% vs. 3.6% (p < 0.01)], and evacuation [48.7% vs. 23.6% (p < 0.01)] phases of shock. Conversely, intensivists were more likely to utilize scheduled diuretics than nephrologists [47.1% vs. 28.2% (p = 0.04)] later on in the patient course. Most physicians believe that discussing fluid balance and deresuscitation is important. Nevertheless, when to initiate deresuscitation and how to accomplish it differed between nephrologist and intensivists. Widely understood and operationalizable definitions, further research, and eventually evidence-based guidelines are needed to help guide care.

Differences in time perception in patients with obstructive sleep apnea.

Obstructive sleep apnea (OSA) is a condition that occurs due to complete (apnea) and partial (hypopnea) obstruction in the upper airways during sleep. Hypoxia is one of the key factors contributing to the development of symptoms of obstructive sleep apnea and OSA-related diseases. The present study aimed to evaluate time perception differences between patients with OSA and healthy individuals, as well as among different OSA severity groups. Twenty severe OSA, twenty moderate OSA, twenty mild OSA patients, and twenty healthy volunteers without OSA were included in the study. Scales were administered to the participants. Time perception tests were administered to evaluate perceptual timing. In the paced motor timing test, a difference was observed between the OSA ( +) group and the OSA (-) group. In the Time Estimation Test, a difference was observed between the OSA ( +) group and the OSA (-) group and their subgroups. The internal clock works slower in the OSA ( +) group. When subgroups were compared based on the degree of OSA, the internal clock worked slower as we transitioned from the OSA (-) group to the severe OSA group. It is considered that as you move from the OSA (-) group to the severe OSA group, the switch between pacemaker and accumulator is disrupted due to the decrease in attention. Recurrent hypoxia observed in OSA may alter the perception of time by affecting attention.

Psychometric Assessment of the Temporal Bisection Task with Discrete and Continuous Response Formats

Abstract The temporal bisection task has long been used to study time perception as well as measure individual differences in time perception ability. The task involves training participants on short and long reference durations before presenting intermediate durations and asking participants to classify them as ‘short’ or ‘long’. However, there is little information about how well the bisection task measures individual differences in timing ability. To bridge this gap, we assessed the psychometric properties of measures obtained from a classic temporal bisection task: Weber ratio and percent correct. Because measures with binary responses tend to require many trials to reach adequate reliability, we also assessed the psychometric properties of a modified bisection task which used a continuous response format. In this task, participants represented intermediate durations on a visual analogue scale. Estimation error was used as the outcome measure. Participants (n = 46) completed the classic and modified bisection tasks twice across two sessions approximately one week apart. The modified bisection task had excellent internal consistency and test–retest reliability, while the classic task had fair to good internal consistency and good test–retest reliability. Overall, estimation error had the highest reliability, followed by percent correct, and then Weber ratio. In terms of validity, there was excellent convergent validity between the classic and modified bisection tasks. As an exploratory analysis, we assessed how the number of trials affected the reliability of each outcome measure across the two tasks. Based on this, we make recommendations on how to optimize reliability for both tasks in future research.

Exploring Electrophysiological Responses to Hypnosis in Patients with Fibromyalgia

Background/Objectives: Hypnosis shows great potential for managing patients suffering from fibromyalgia and chronic pain. Several studies have highlighted its efficacy in improving pain, quality of life, and reducing psychological distress. Despite its known feasibility and efficacy, the mechanisms of action remain poorly understood. Building on these insights, this innovative study aims to assess neural activity during hypnosis in fibromyalgia patients using high-density electroencephalography (EEG) and self-reported measures. Methods: Thirteen participants with fibromyalgia were included in this study. EEG recordings were done during resting state and hypnosis conditions. After both conditions, levels of pain, comfort, absorption, and dissociation were assessed using a numerical rating scale. Time perception was collected via an open-ended question. The study was prospectively registered in the ClinicalTrials.gov public registry (NCT04263324). Results: Neural oscillations showed increased theta power during hypnosis in the left parietal and occipital electrodes, increased beta power in the frontal and left temporal electrodes, and increased slow-gamma power in the frontal and left parietal electrodes. Functional connectivity using pairwise-phase consistency measures showed decreased connectivity in the frontal electrodes during hypnosis. Graph-based measures, the node strength, and the cluster coefficient were lower in frontal electrodes in the slow-gamma bands during hypnosis compared to resting state. Key findings indicate significant changes in neural oscillations and brain functional connectivity, suggesting potential electrophysiological markers of hypnosis in this patient population.

Music in the Air and in the Body: An Interoceptive System's Perspective on Musical Emotions, Awareness, and Time.

Performing and perceiving music requires the integration of multimodal information, including sensations of one's own body. Research on musical engagement investigated emotional responses and the peripheral physiological activations involved, as well as bodily action tendencies, effects on time perception, and the role of awareness and focus of attention. The concept of interoception dedicates a central role to the insular cortex, as suggested by Craig and others, and offers a unifying framework for studying music as an activity that has always had a key role for individuals, groups, societies, with a strong bodily component. Chances and challenges of an interoceptive perspective on music are discussed.

Developing automaticity in neural speech discrimination in typically developing bilingual Italian-German and monolingual German children.

Many studies have shown that input in more than one language influences children's phonemic development. In this study, we examined the neural processes supporting perception of Voice Onset Time (VOT) in bilingual Italian-German children and their monolingual German peers. While German contrasts short-lag and long-lag, Italian contrasts short-lag and voicing lead. We examined whether bilinguals' phonetic/phonological systems for the two languages develop independently or whether they influence each other, and what role language input plays in the formation of phonetic/phonological categories. Forty five-year-old children (16 monolingual German, 24 bilingual Italian-German) were tested in an oddball design expected to elicit a neural Mismatch Response (MMR). The stimuli were bilabial stop VOT contrasts with the short-lag stop, common to both languages, as the standard. Four deviant VOTs were selected: 92 ms and 36 ms lag for German; 112 ms and 36 ms voicing lead for Italian. Bilingual children's language background was assessed using a caregiver questionnaire. Italian-German bilingual 5-year-old children and German monolingual controls showed similar MMRs to German long-lag and Italian voicing lead VOT, except for the 36 ms long-lag deviant; this acoustically difficult distinction did not elicit a robust negative MMR in the bilingual children. The lack of a difference between the bilinguals and monolinguals for voicing lead suggests that the amount of input in Italian for the bilinguals was not sufficient to lead to an advantage compared to the monolingual German children. Alternatively, the finding could indicate that voicing lead is easier to discriminate than voicing lag.

Interoceptive and Bodily Processing in Prospective and Retrospective Timing.

This chapter reviews some directions along which Craig's proposal of subjective time as emergent from interoceptive and bodily dynamics allows to frame recent findings on prospective and retrospective time processing. Behavioral and neuroimaging evidence from prospective timing studies demonstrates that an interoceptive-insular system may support the development of a primary representation of time in the context of large-scale networks involved in duration processing. Studies showing a tight link between episodic memory and interoceptive, emotional, and sensorimotor states further provide insights on processes supporting retrospective timing. These lines of evidence show that acknowledging its dependence on bodily states is most likely a crucial step toward a mechanistic understanding of time perception.

Telemedicine and time management in primary care.

Information and communication technologies (ICTs) can enable workers to structure work in novel ways, allow for better time management, and increase work scheduling autonomy. Time management and work scheduling are important factors in the field of clinical practice in primary care. Time limits on consultation are a key constraint on the delivery of good care since the length of patient-physician consultation impacts its quality. This research aimed to examine the experiences of primary care physicians (PCPs) when using telemedicine technologies (TTs), a type of ICT, in their communication with patients. During 2023 in-depth interviews were conducted with 20 Israeli PCPs: family physicians and pediatricians. Perception and management of time emerged as a focal subject in the interviews. The PCPs interviewed described several effects of TTs on time management in primary care. They portrayed TTs as saving time for patients and having a mixed effect on the healthcare organization: both saving and wasting their work time. TTs were described as impacting their time management in the context of work-life balance, allowing them to manage their time during and between appointments. For PCPs, TTs can be beneficial for managing time in the clinic, which can contribute to better healthcare. This article, concerning TTs as a type of ICT, contributes to the existing literature which suggests that ICTs can allow for better time management and increase work scheduling autonomy. It also presents several recommendations for better implementation of TTs in healthcare organizations.

Investigating the Kappa Effect Elicited Through Concurrent Visual and Tactile Stimulation.

The experience of time and space in subjective perception is closely connected. The Kappa effect refers to the phenomenon where the perceived duration of the time interval between stimuli is influenced by the spatial distance between them. In this study, we aimed to explore the Kappa effect from a psychophysical perspective. We investigated participants' perception of temporal duration in the sub-second range by delivering visual and tactile inputs through wearable devices placed on both the palm and the forearm. We compared the impact of unimodal sensory stimulation, involving either visual or tactile stimuli, with different bimodal stimulation conditions. Our results revealed that the illusory effect on inter-stimulus duration perception can be observed in both unimodal conditions, although the distortions were significantly more pronounced in vision. In the multimodal stimulation condition, where visual stimuli were presented at non-equidistant spatial locations, the integration of tactile input did not reduce the Kappa effect, regardless of the spatial location of the tactile stimuli. However, when the visual stimuli were equidistant in space, regardless of the spatial location of the tactile stimuli, the Kappa effect disappeared. These results can shed light on the effect played by multimodality on the perception of space and time.

Synthesis of Arts by means of Sculpture Forms

The purpose of the work is to characterise the syncretism of sculptural forms in the development of monumental Ukrainian sculpture; emphasise the national features of the development of national sculpture on the example of the works of modern Ukrainian sculptors. The methodology of the work consists in the principles of holistic and systemic approaches to the study of the synthesis of arts in the sculptural forms of Ukrainian artists. An analytical method was applied to study scientific approaches to the synthesis of arts, as well as an artistic-stylistic method, as well as a system-functional method to the structuring of artistic works as a phenomenon of modern monumental sculpture. The scientific novelty of the study consists in the discourse on the synthesis of arts in the art history environment, characterising some works of art that belong to the category of monumental sculpture. Conclusions. It should be noted that in the Ukrainian art space there is a synthesis between classical forms and intermedia installations, which creates a complex and multi-layered context for modern artists. The perception of time, space and material becomes plastic and changeable, and this, in turn, stimulates the development of new aesthetic forms. Sculptural images have a significant influence on the formation of styles of young artists, where the emphasis is not only on silhouettes, but also on specific elements originating from various forms. Artists build associative visual sequences, embodying unrealistic, yet deeply symbolic images that resonate with viewers on an emotional level. In the examples from the workshops you mentioned, we see how a variety of materials and art forms and execution methods are used to create coherent and complete images that reflect the synthesis of different arts. The theme of the synthesis of arts in different sculptural forms, which sometimes seem completely incompatible, is indeed one of the most relevant for research.

EFETIVIDADE DO MINDFULNESS NA PERCEPÇÃO DO TEMPO EM PESSOAS SAUDÁVEIS: UMA REVISÃO SISTEMÁTICA

Mindfulness meditation has shown very promising results in modulating experiential awareness of the present moment. These results have sparked interest in research into this technique in the experience or awareness of the passage of time (time perception). However, there is a lack of studies that systematically examine its effects in healthy people. The objective of this systematic review is to summarize the studies that evaluated the effectiveness of mindfulness in the perception of time in healthy people. A search in the PubMed, Web of Science, Embase and LILACs databases was carried out from 2013 to 2024, using the following key words: meditation, mindfulness, time perception, Underestimation and overestimation of subjective time. 239 studies were found, of which 10 met the eligibility criteria. Limitations of this study encompass a number of aspects including the paucity of data available for certain categories of outcomes, suggesting a significant gap in existing research. Regarding temporal perception, no homogeneity of results was found that expresses the relationship between mindfulness and overestimation, underestimation or stabilization of time.

Dual-Stage Analysis Combining Structural Equation Modeling and Machine Learning for Low-Carbon Travel Intention of Urban Residents

Guiding urban residents to travel with low carbon is an important measure to reduce carbon emissions and promote sustainable urban development. To explore the important factors affecting urban residents’ low-carbon travel intention, this study proposes a composite model of urban residents’ low-carbon travel intention based on the composite framework of the theory of planned behavior and value belief norm theory. A total of 398 valid pieces of data were collected in Qingdao, China. Structural equation modeling (SEM) was applied to empirically analyze the data to identify the predictors that have a significant effect on low-carbon travel intention. Then, two machine learning methods, artificial neural networks (ANN) and extreme gradient boosting (XGBoost), were used to conduct sensitivity analysis on the SEM results to identify the determinants that affect residents’ low-carbon travel intention. The results showed that personal norm, attitude, subjective norm, and perceived behavioral control have a significant direct effect on residents’ low-carbon travel intention. Policy factors can indirectly affect low-carbon travel intention, through mediating variables. Environmental awareness and travel time perception have a direct effect on both residents’ attitude and subjective norms. In addition, the explained variance (R2) of low-carbon travel intention by ANN and XGBoost is 0.75 and 0.77, respectively. The Root Square Mean Error (RMSE) in both models are small, which verifies the effectiveness of the two machine learning methods. The results can provide a reference basis for policymakers to prompt urban sustainable development.
