Motoric and Perceptual Kinesthetic Symmetry in Bi-manual Interactions

Bi-manual (two-handed) actions have shown notable success in rehabilitative and therapeutic applications from the point of motor symmetry. Recent studies have shown that symmetry in actions is attributed to sensorimotor perception than mere co-activation of homologous muscles. In this paper, we present a study of symmetric and asymmetric haptic (specifically force) feedback on human perception and motor action during bi-manual spatial tasks. To the best of our knowledge, ours is the first procedure to specifically test the perceptual aspect of bi-manual actions in contrast to other works that typically characterize the physical/bio-mechanical aspects. Thereby in our experiment, healthy individuals were tasked with stretching a virtual spring using two symmetrically located haptics devices that provide an equal amount of resistive force on each hand while pulling the spring. In this experiment, we implement four kinesthetic conditions, namely (1) feedback on both hands, (2) feedback only on dominant hand, (3) feedback only on non-dominant hand, and (4) no feedback as our control. Our first goal was to determine if there exists a range of spring stiffness in which the individual incorrectly perceives bi-manual forces when the feedback is deactivated on one hand. Subsequently, we also wanted to investigate what range of spring stiffness would lead to such perceptual illusions. Our analysis shows that not only does such a range exist, it is wide enough so as to be potentially utilized in future rehabilitative applications.

SEMANTICS OF UNREALITY IN THE WORKS OF V. PELEVIN: THE PERCEPTUAL ASPECT

Введение. Представлено исследование семантики восприятия, возникающей в процессе описания ирреальности как объекта чувственного опыта в творчестве В. Пелевина. Языковые единицы с перцептивной семантикой, обладая функционально-эстетической нагрузкой, играют важную роль в реализации формальных и смысловых аспектов организации художественного текста. Цель – изучить особенности языковой репрезентации феномена ирреальности в творчестве В. Пелевина на основе структурно-семантических моделей высказывания и лингвистических средств выражения семантики восприятия. Материал и методы. Исследование осуществляется при помощи метода лингвистического моделирования, нацеленного на изучение базовых компонентов структуры высказывания, и лингвостилистического анализа. В качестве материала выбран постмодернистский текст, который отражает активные процессы, происходящие в языковой системе, в частности романы В. Пелевина «Чапаев и Пустота» и «Generation „П“» (1990-е гг.). Результаты и обсуждение. Установлено, что семантика восприятия реализуется на различных уровнях организации художественного текста. На структурно-семантическом уровне высказывания, помимо базовой модели перцептивной ситуации, выявлены модели, позволяющие актуализировать ирреальные объекты, которые становятся доступными чувственному восприятию персонажей. Для замещения позиции объекта чаще используются абстрактные и конкретные имена существительные и местоимения. Имена прилагательные и причастия, выступающие в качестве квалификатора, описывают разнообразные характеристики воспринимаемого. На уровне формальной организации текста репрезентация семантики ирреального обусловила усложнение синтаксического строя произведения (использование различных типов сравнительных конструкций, сопоставительных и противительных бессоюзных предложений, сложноподчиненных предложений с придаточными места и времени и др.). На стилистическом уровне семантику ирреальности реализуют средства художественной выразительности (метафора, метонимия, сравнение, персонификация и др.), в состав которых входят языковые единицы с перцептивным значением. Заключение. Репрезентация семантики ирреальности в творчестве В. Пелевина тесно связана с изображением перцептивных процессов. Особая роль отводится объектам восприятия, которые, обладая необычными качественными характеристиками, становятся предметом языковой актуализации на разных уровнях художественного текста. Introduction. The article presents the study of the semantics of perception, which is observed in the process of describing unreality as an object of sensory experience in the works of V. Pelevin. Language units with perceptual semantics having a functional and aesthetic meaning play an important role in the implementation of formal and semantic aspects of the organization of a literary text. The purpose of the article is to study the linguistic features of the representation of the semantics of unreality in the work of V. Pelevin on the basis of the identified structural and semantic models of the statement and linguistic means of expressing the semantics of perception. Material and methods. The research is carried out using the method of linguistic modeling aimed at identifying the main components of the utterance structure and linguistic and stylistic analysis. The material chosen is a postmodern text that reflects the active processes taking place in the language sys-tem in particular V. Pelevin’s novels «Chapaev and the Void» and «Generation “P”» which relate to the mature period of the writer’s work (the 1990s). Results and discussion. In the course of the research, it was revealed that the semantics of perception is implemented at various levels of the organization of a literary text. In addition to the basic model of the situation of perception at the structural-semantic level of the utterance, there are models that make it possible to actualize unreal objects. In such circumstances, these objects become accessible to the sensory perception of characters. Abstract and concrete nouns and pronouns are more often used to replace the position of an object. Adjectives and participles that act as qualifiers describe various char-acteristics of the perceived. At the level of the formal text organization, the representation of the se-mantics of the unreal caused the complexity of the syntactic structure of the work (the use of various types of comparative sentences, complex sentences, adverbial clauses of place and adverbial clauses of time, etc.). At the stylistic level of the text, the semantics of unreality are implemented by stylistic devices and expressive means which include language units with perception meaning. Conclusion. The study allows us to conclude that the representation of unreality semantics in the work of V. Pelevin is closely related to the image of perceptual processes. A special role is assigned to perception objects with unusual qualitative characteristics which become the subject of language actualization at different levels of the literary text.

A comprehensive cognitive-perceptual model of analysis for contextually determined components of a conceptualized term

The authors analyze major features of complex multidisciplinary analysis models of the recipient’s perceptual capacity related to desobjectifying contextually determined transdisciplinary borrowing of newly emerging components within a semantic hierarchy. Critical analysis and comparison are applied to some alternative approaches in linguistic studies of transdisciplinary terminologization. There is a role revealed, which belongs to the cognitive-perceptual aspect in the respective knowledge field. The comprehensive phenomenon of component transgression within the meaning hierarchy is viewed from different angles: metaphoric and metonymic explication, and from the stance of conceptual integration of mental spaces and grammatical constructions of implicit meaning generation. The semantic foundations of the frame & semantic model of the borrowing theory serve a prototype of a comprehensive analytical model relevant not only in Linguistics, yet in other humanities (Literature, Psychology, Sociology). The comprehensive method of bottom-up analysis in studying explication of contextually determined overtones (forced reinterpretation of terms and terminoids) implies desobjectification of the semantic hierarchy at several levels. The analysis suggests that standard linguistic mechanisms can be employed through deautomation in the said cognitive modeling function. Reactivating a prototypical mental image within a new reflexive space is viewed as the most effective way of explicating the respective components.

Knowledge Sharing Practices Amongst the Library and Information Professionals of Pakistan in the Digital Era

We are living in the age of an ever-changing knowledge-based society. Information, and most preferably knowledge, has been considered as a noteworthy resource for the development of any person, profession, institute, nation, and even all humanity on a larger scale. Knowledge sharing (KS) is a significant activity and an integral part of knowledge management. KS is substantial in building the capacity and learning development of library and information professionals. The aim of this article is to find out knowledge sharing practices among the library and information professionals working in different libraries in the Pakistani digital era. The study will be limited to the perceptual aspect of the issue, specifically from the respondents' opinions and their sentiments. Finally, the article highlights the role, skills and challenges for information professionals while sharing knowledge in the digital era of Pakistan.

The Perceptual and Aesthetic Aspects of the Music-Paintings Congruence

The purpose of the present study is to investigate the effect of congruence between music and paintings on the aesthetic preference of paintings. Congruence was specified as the similarity in perceived regularity and the complexity of jazz compositions and abstract paintings (the ratings of regularity and complexity in both sets of stimuli were obtained in the pilot study). In the main experiment, 32 participants rated the aesthetic pleasantness of paintings with congruent, incongruent, and no music background. In addition, they rated the music-paintings matching (how well the music goes with the painting). The results show no effect of congruence on aesthetic pleasantness ratings. The effect on the perceived matching was significant; matching is higher in the congruent compared to the incongruent condition. These findings suggest that congruency has a strong effect on the perceptual aspect of the music-paintings compatibility (visuo-auditory similarity) and no effect on the aesthetic aspect (liking).

OBJECTIVES/SPECIFIC AIMS: Attention is a cognitive function that binds perception and behavior. Recent evidence suggests that attention involves phase-amplitude coupling (PAC) of neural signals. PAC occurs when the amplitude of one frequency (frequency for amplitude) is maximal at particular phases of another frequency (frequency for phase). However, some studies suggest PAC improves attention, while others maintain that PAC inhibits attention. The present study seeks to determine whether PAC promotes or inhibits neural signals that underlie attention. METHODS/STUDY POPULATION: Six adult epilepsy patients with implanted electrodes participated in a cued attention task. Subjects participated in a cued attention task where they oriented attention to one side of the screen at a time and discriminated between stimuli as fast as possible with mouse clicks. Perception-related electrodes discriminated the location and/or shape of the target. These were determined with a cluster-based permutation test. Behavior-related electrodes predicted reaction time (RT) with neural activity prior to target appearance. These were determined with correlations between PAC and RT. PAC was calculated using the modulation index (MI). RESULTS/ANTICIPATED RESULTS: We found 47 perception-related electrodes that discriminated location and/or shape of target (p<0.05, FDR corrected). We found 27 behavior-related electrodes where PAC prior to the target predicted RT (p<0.05 FDR corrected). There was little overlap between the perception-related and behavior-related electrodes (3%). PAC also did not discriminate left-sided and right-sided cues. In addition, behavior-related electrodes had less local neural activity and higher PAC during the period of cued attention than perception-related electrodes. DISCUSSION/SIGNIFICANCE OF IMPACT: PAC minimally facilitates perceptual aspect of visual attention. However, PAC facilitate response speed. We suggest that PAC might improve response speed by “quieting” task irrelevant neural activity. For the same reason, PAC is absent in electrodes that are actively processing meaningful streams of visual data. These findings highlight separable aspects of the human attention system and how PAC contributes to both. Future directions include determining differences in PAC for attentional disorders like ADHD and neurological neglect.

Object Domains and the Experience of Beauty

The purpose of the present study was to specify whether the structure of the experience of beauty is domain-specific or domain-general. Five basic descriptors of the experience of beauty were specified: two central descriptors, Beauty and Attractiveness, and three descriptors that represented different 16 aspects of Beauty: Pleasure (hedonic aspect), Harmony (perceptual aspect), and Interestingness (motivational aspect). Four groups of 25 participants rated different sets of visual stimuli on the five bipolar seven-step scales: Beautiful–Ugly, Attractive–Repulsive, Pleasant–Unpleasant, Harmonious–Disharmonious and Interesting–Boring. In preliminary studies four sets of stimuli were extracted: (1) environmental scenes, (2) human faces and bodies, (3) abstract forms and (4) artworks. Correlations between descriptors, and multiple regression analyses revealed that, in all of the categories of objects, attractiveness was consistently closer to pleasure than harmony and interestingness. The relationships between the other descriptors were category-specific: beauty was closer to pleasure in cases of environmental objects and artworks and it was closer to harmony in the case of human faces and bodies and abstract forms. These results suggest that the structure of the experience of beauty is partially general to all categories of objects and partially domain-specific.

Addressing Complexity Aspects in Conceptual Ship Design: A Systems Engineering Approach

This article approaches the complexity aspects of conceptual ship design from a systems engineering point of view. We introduce the issue by defining the term complexity in systems engineering, placing the conceptual ship design task as a complex system problem and creating analogies between generic complex systems and a ship. Five main aspects of complexity are presented, linking challenges of the conceptual phase to each of the aspects. The structural aspect is related to the arrangement and interrelationship of the physical objects in the ship. The behavioral aspect derives from the form-function mapping. The external circumstances to which the ship is subjected are approached through the contextual aspect. Uncertainties in the scenarios and changes over time are related to the temporal aspect. The perceptual aspect relates to how stakeholders perceive the value that they receive from a chosen design. A theoretical study to address these five aspects is presented, applying the responsive systems comparison method in the conceptual design of an anchor handling a tug supply vessel. The last section discusses why decomposing the complexities of the ship design task in five aspects is a benefit.
