La costumbre de “pintar mayos” y “echar ramos” en las paredes del Campo de Montiel. El ocaso de una tradición
Authors: Maldonado Felipe Miguel Antonio
Published: January 2022

Hasta hace pocas décadas, la popular costumbre de “pintar mayos” y “echar ramos” en las fachadas de las jóvenes casaderas, resultaba práctica común en los pueblos del Campo de Montiel. Manifestaciones del proceso de galanteo que, en su contexto originario, como verdaderas declaraciones amorosas, está prácticamente desaparecido en la mayoría de ellos, manteniéndose en algunos, tan solo, de forma testimonial. La evolución en el terreno conceptual, espacial y, sobre todo, en el contexto iconográfico y estilístico de escrituras y motivos de mayos en esta Comarca, queda acreditada en las representaciones estudiadas y analizadas en el presente artículo.
Desde el Campo de Montiel: colonos españoles en Sierra Morena
Authors: Pérez-Schmid Fernández Francisco José
Published: January 2022

Las Nuevas Poblaciones de Sierra Morena y Andalucía se fundaron a partir de 1767 con colonos extranjeros y españoles, siendo el origen de una nueva Intendencia que estuvo vigente hasta 1835. En su sustrato poblacional identificamos población natural de algunas de las villas del Campo de Montiel, en la antigua provincia de La Mancha, lo que nos ha llevado a analizar la documentación existente en distintos archivos buscando su presencia e influencia. Además, la cercanía geográfica de sus términos nos advierte de las relaciones de vecindad que se han desarrollado entre sus habitantes desde la creación de las colonias y que posee su reflejo en la actualidad.
Las campanas y sus toques en Torre de Juan Abad

Published: January 2022

El lenguaje de las campanas representa un patrimonio cultural inmaterial y litúrgico genuino de cada pueblo. Las campanas han servido desde hace siglos como medio de comunicación y cohesión social, marcando los ritmos diarios de la vida en el pueblo. Por desgracia, en las últimas décadas, el abandono rural, los cambios litúrgicos y la mecanización de las campanas, han repercutido negativamente en la conservación de este patrimonio. En Torre de Juan Abad (Ciudad Real) se han conservado unas grabaciones de todos los toques originales de la parroquia de los años 60, lo que supone la posibilidad de estudiar y documentar todo el repertorio de toques que se ejecutaba en dicho pueblo, permitiendo, en un futuro, implementarlos nuevamente en la parroquia.

ORGANISATIONAL APPROACHES TO THE FORMATION OF SOCIAL RESPONSIBILITY OF HIGHER EDUCATION INSTITUTIONS IN THE MARKET OF EDUCATIONAL SERVICES
Authors: Yatsenko Valentyna
Published: January 2022

BACKGROUND AND OBJECTIVES. Social responsibility is a system of innovative working relationships that acts as an essential technology that enhances the effectiveness of a higher education institution with employees, partners, customers and the community, and ultimately contributes to its prosperity and civil society. Social responsibility should focus on enhancing the image of the higher education institution, recognising its successes in society by civil institutions and individual citizens. This will increase the social value of the higher education institution, its competitiveness, sustainability and efficiency, allowing society to use the resource voluntarily provided by the higher education institution to balance organisational and social interests.METHODS. The methods used to conduct the research were: interview, expert. The questions selected for this study were taken either from the literature or from individual interviews. The literature helped to identify important dimensions of the concept of social responsibility. The interviews helped to identify new points and possible dimensions to contextualise organisational approaches to shaping the social responsibility of higher education institutions.FINDINGS. Organizational approaches to the formation of social responsibility of higher education institutions in the market of educational services are proposed. Mechanisms to increase socio-commercial value of socially responsible higher education institutions are argued: creation of public institutions to identify, formulate public interests and present them to corporations; selection of social projects taking into account stakeholder expectations.CONCLUSION. In order to increase the efficiency of using the principles of social responsibility in HEIs, to improve their ratings, students' competitiveness in the labour market and their involvement in the task-setting and decision-making process, it is necessary to develop a programme of corporate social activity, which can become the basis for developing the HEIs' development strategy. The formation and adoption of such a strategy should be based on the interests of all stakeholders, based on the core values of the university to achieve the indicators at micro-, meso- and macrolevels.
USING THE UNIVERSITY'S ENERGY EFFICIENCY KNOWLEDGE HUB FOR ENERGY RENOVATION AND ENERGY MODERNIZATION OF UNIVERSITY BUILDINGS
Authors: Shcherbak Valeriia
Published: January 2022

BACKGROUND AND OBJECTIVES. The most important socio-economic task in the current period is to transfer Ukraine's economy to an intensive way of development in order to improve the level and quality of life of the population and solve the full range of social problems. Implementation of such a policy dictates the need to solve problems of reconstruction and modernization of buildings and structures, primarily related to the public sphere (including higher education institutions), in order to eliminate the existing inconsistency of the technical condition and functional and consumer qualities of public buildings to current standards and consumer requirements. Therefore, one of the most urgent directions of development of higher educational institutions is the task of providing effective overhaul and reconstruction of buildings, increasing their energy efficiency.METHODS. The theoretical and methodological basis of the study were the fundamental and applied developments of leading domestic and foreign scientists in the theory and practice of management of energy modernization and energy reconstruction of buildings, increasing energy efficiency of buildings. The factual basis of research were the legislative acts of Ukraine in the field of energy efficiency, normative and methodical documents on the modernization and reconstruction of buildings, Directive 2010/31/EC in the field of energy saving. When solving specific tasks the methods of system and comparative analysis, economic-mathematical methods of efficiency evaluation of energy reconstruction and energy modernization projects were used.FINDINGS. The method of calculation of the reduced resistance to heat transfer of the enclosing structures and the shell of the 4th building of Kyiv National University of Technology and Design as a whole taking into account the temperature and humidity conditions in the fencing marginal zones. It is shown that in the enclosure edge zones the heat protective properties decrease resulting in a deterioration of the heat protection of the whole building. Practical recommendations for the design of fencing structures of modern buildings taking into account the temperature-moisture regime are proposed.CONCLUSION. For the analysis of complex processes of moisture transfer in enclosures, a mathematical model based on the moisture potential is most convenient. A certain difference from the thermal potential (temperature) to the definition of the moisture potential allows to diagnose the most general assessment of the moisture regime of exterior and interior fences on the basis of HUB knowledge on energy efficiency. At use of this model it is possible to consider process of moisture exchange in a wide range of humidity and temperature taking into account movement of a moisture as a basis of carrying out energy reconstruction and energy modernization of operating buildings of the university.
ADAPTATION OF STUDENTS TO RESEARCH AND PROFESSIONAL ACTIVITIES BASED ON THE USE OF THE UNIVERSITY HACKATHON ECOSYSTEM
Authors: Goncharenko Iryna
Published: January 2022

BACKGROUND AND OBJECTIVES. For student youth the process of entering the profession and harmonization of interactions with professional environment and future professional activity is the key moment of life activity. This process, according to the majority of modern researchers, is a certain complexity and contradiction both for students and for higher education institution, as well as social institutions and organizations acting as social customers.METHODS. The study of the process of adaptation of student youth to research and professional activity was carried out on the basis of the Kyiv National University of Technologies and Design. Assessment of students' expectations regarding studies, the level of students' awareness of the future professional and scientific activity was carried out with the help of the University Hackathon Ecosystem toolkit. Processing of the obtained results of the survey was carried out on the basis of the "Methodology of research of students' adaptability to dual education in higher education". The methodology includes two scales: adaptability to professional activity and adaptability to research activity.FINDINGS. The following directions of training are distinguished: professional, social and research, as well as stages of adaptation to professional training: learning identification, learning-professional activation, professional-value reflection. Integration of these directions allows us to organize activities that ensure formation of necessary professionally important qualities (competences) in students (graduates), agreed with potential employers and demanded by the corresponding profession. The conducted experiment on the basis of Hackathon-ecosystem of the university was carried out taking into account the directions of training and their corresponding adaptation criteria: professional direction – activity-result and motivation-value criteria; humanitarian – communication-professional criterion; research – personal-creative criterion.CONCLUSION. Students' adaptation to future professional and research activities can be defined as one of the most urgent social problems at the pre-production stage. This is due to the fact that the student spends one of the main periods of his life in a higher education institution, since it is at this time he is formed as a professional and as a person, masters the necessary competencies in order to achieve a certain professional and research level. At this stage the professional intentions of the individual and the requirements of the profession come into alignment, i.e. there is an adaptation to professional and research activities.

Purpose. To study the influence of the carbonizing agent structure on the formation of thermal insulating char layer of intumescent system acid donor/polyol and on the fire protection efficiency of the system at high temperatures. Methodology. A fire retardant mixture of an acid donor (phosphates ammonium, urea, melamine)/ polyol was chosen as a model intumescent system. Dispersion of vinyl acetate copolymer with ethylene was used as a polymeric component. The study applied the characteristics of the char layer of the intumescent composition at a certain temperature. The volumetric intumescent coefficient (K, cm3/g), mass of char residue (m, %), structure and density of the char layer are proposed as the main estimated parameters of flame retardant effect. IR spectroscopy was used to identify products of thermolysis of intumescent systems. Determination of fire protection efficiency of intumescent coatings was carried out in a mini-oven under standard fire conditions. Findings. The influence of polyol structure on the formation of thermal insulating char layer of intumescent acid donor/polyol system and the prediction of fire protection efficiency of this system under high temperature conditions has been investigated. It has been shown that under conditions of thermal shock the fire protection efficiency is more dependent on the nucleophilic reactivity of the polyol towards the unsaturated phosphorus atom of the acid donor than on its thermal stability. It has been found that pentaerythritol, dipentaerythritol, starch, dextrin, xylitol and sorbitol are the most effective carbonizing agents, regardless of the structure of the acid donor. It has been proved by infrared spectroscopy that at high temperatures as a result of the decomposition of pentaerythritol one of the reaction products is the aldehydes interacting with pentaerythritol with the formation of oligomeric compounds with a simple ether bond C-O-C. At the same time, pentaerythritol can be considered as a universal source of carbon framework for intumescent flame retardants regardless of the phosphate structure used. Originality. It has been shown that an important factor to increase the fire protection efficiency of intumescent systems is the use of polyols with an increased nucleophilicity in the esterification between polyol and phosphoric acid.Practical value. The optimal polyols as carbonizing agents for formulation of intumescent coatings with enhanced fire protection properties have been determined.

This study attempts to address the issues of enhancing energy efficiency using mathematical modeling methods. The research findings assert that energy saving is a new challenging task of the 21st century, since thermal and electric power consumption is essential to human life and building a favourable living environment. It is observed that boosting the competitiveness, financial stability, energy and environmental security of Ukraine’s economy, as well as improving the living standards and the life quality seem hardly possible without realizing the energy saving potential and increasing energy efficiency through modernization, technological advancements and the transition towards rational and environmentally responsible utilization of energy resources. It is argued that by resolving the above objectives, Ukraine might strengthen its positions among developed economies. The following methods were used to carry out mathematical modeling to enhance the university energy efficiency in the frameworks of the energy knowledge hub: neural network technologies, mean absolute and relative error, mean absolute deviation; statistical comparison of the forecast accuracy based on the mean absolute error, as well as time series forecasting. A model to boost the University energy efficiency has been developed within the knowledge energy hub by implementing neural network patterns based on the experimental data from the Kyiv National University of Technologies and Design for the heating period 2020–2021. In particular, to optimize the operating modes of automatic power supply control for University Building 4, mathematical models with a complex algorithm structure have been employed (offering the increased resource intensity of such tasks). It is argued that making a decision on the feasibility of using an energy hub for University buildings and selecting appropriate equipment should be accomplished with due regard to the structure and the capacity of energy consumers, their types, demands for quality and reliability of electric power supply, their compliance with operating and safety standards, as well as taking into account the results of climate, wind monitoring and monitoring of solar activity. The conclusions resume that to assure the energy quality and the system sustainability, it is considered important to resolve a range of issues related to inconsistency in generation and supply of renewable energy from power plants, ensuring reliability and quality of energy supply through the use of energy storage (batteries) in particular, etc.).

This paper offers an argument for the need to providing further research on improving energy efficiency and searching for modern management methods based on the university energy innovation knowledge hub. The findings have revealed that the specific energy consumption in the Ukrainian economy is unjustifiably higher than that of other European countries and countries with transitive economies. It is noted that economic losses are becoming increasingly apparent in the context of high cost of imported energy resources, low level of energy security, incompetitiveness of industries and significant environmental wastes. The research methodology entails the principle of studying and summarizing factual data on enhancing energy management and quality management systems, as well as the university documentation. To attain the research agenda, the following methods have been employed: the system and structural analysis techniques, management theory, methods of diagnostics and identification, graph theory as well as energy balance methods. The study presents a mechanism of energy efficiency and energy saving management based on the university energy innovation knowledge hub. The findings demonstrate that such a mechanism is able to overcome the rejection by economic actors of innovation technologies in general and energy efficient technologies in particular. The proposed mechanism of energy efficiency and energy saving management based on the university energy innovation hub challenges the implementation of specific economic measures that should include such elements as incentives (motivators) for energy saving, energy market infrastructure and energy efficient technology, energy projects funding sources and tools. The conclusions resume that in modern realia, higher education institutions should promote a shift from a formally declared energy saving policy towards a University energy efficiency economy pattern as an energy autonomy driver, building a strategy for combining indicative and market functions in ensuring energy efficiency.

The effect of ethanol on some hematological parameters of the australian red claw crayfish (Cherax quadricarinatus)
Authors: Skafar D. , Shumeyko D.
Published: January 2022

Purpose:to study the effect of ethanol on the parameters of THC, the percentage of granulocytes and total protein in the hemolymph of the Red claw crayfish (Cherax quadricarinatus).

Materials and methods.The object of this experiment was 26 males of the Australian red-clawed crayfish (Cherax quadricarinatus) weighing from 23 to 83 g. The individuals were evenly divided into two experimental groups - with an injection of ethanol and a control group without an injection of 13 crayfish for each group. The injection dose was 2515 mg per 100 g of body weight. A day after the introduction of ethanol, hemolymph was taken with a syringe from the ventral sinus, the syringe was pre-washed with a 4% EDTA-Na2 solution. Three parameters were determined: the total hemocyte count (THC), percent granulocytes and percent total protein content. Counting of hemocytes and determination of granulocytes were performed in a Goryaev chamber under a light microscope. The total protein was determined by the refractometric method.

Results.Differences in THC and total protein between the groups were statistically unreliable (p>0,05). THC in the experimental group is 36% more than in the control group. The total protein after the introduction of ethanol actually increased by 0,7%, and relatively by 14%. There were statistically different indicators of the proportion of granulocytes (p<0,05) - the average value of 33,1% in the experimental group versus 24,5% in the control group. A reliable (p<0,05) strong feedback was revealed between the total protein and the mass of individuals in both experimental groups, while in the experimental group there is a visible shift in the values of dependent hemolymph indicators towards an increase in smaller individuals.

Conclusion.A single injection of ethyl alcohol with a dosage of 2515 mg per 100 g of body weight into the hemolymph of C. quadricarinatus does not cause significant changes in the THC and total protein after 24 hours. At the same time, the proportion of granulocytes actually increases by 9%, relative to 37%. This may indicate that granulocytes are involved in the formation of cancer defense mechanisms when exposed to toxic substances. The effect of different dosages of ethanol injections and the duration of its effect on hematological parameters requires additional consideration. It is necessary to investigate its effect on other indicators, such as the pH and buffer capacity of the hemolymph, the concentration of hemocyanin, glucose, lactates and calcium.

THE SEMANTIC STRUCTURE OF THE WORD: POLYSEMY VS BROAD SEMANTIC WORD
Authors: Evteeva M.Yu.
Published: January 2022

The paper deals with the modeling of the semantic structure of polysemantic and broad semantic words. The article suggests determining meanings of polysemantic words as lexical-semantic variants that potentially can be united by means of the invariant meaning though not obligatory for the semantic structure of such words – the invariant meaning of a polysemantic word is seen as something artificial. I argue that it is possible to construct the semantic structure of the broad semantic word on the basis of prototypical meanings which are interpreted as basic meanings. Such prototypical meanings are to be united by the use of a broad invariant meaning. This approach is applied while describing the semantics of the nuclear verbs in the action field (do and make in English, tun and machen in German, делать in Russian). Both types of meanings play a critical role in organizing the semantic structure of the broad semantic words: there is a single invariant while there can be more than one prototype, so that an invariant and definite prototype value is realised in speech. In addition the existence of interdependence of semantic derivation between prototypes and within the meaning itself is assumed. There can be a lot of semantic transfers, but they occur based on a regular cognitive model such as cognitive metaphor and cognitive metonymy. For example, the prototypical meanings of the verbs to do and to make remain the same while the nature of the object changes. Based on the conducted research, a new definition of a broad semantic phenomenon is offered along with distinctive criteria for the phenomena of poly- and broad semantics.

The presence of grinding, mixing, and fractionation of solid components of formulations leads to the formation of aerosols in the air of the working area with a wide range of dispersion of the solid phase - all this characterizes the organization of technological processes for the production of energy-intensive materials. The study aims to give a qualitative assessment of possible air pollution of the working area of energy-intensive materials production by nanoscale aerosols with a solid dispersed phase. The researchers carried out the sampling of the working area air and flushes from solid horizontal surfaces to produce energy-intensive materials. We carried out the sampling by forced circulation of the test air through the absorption devices of Polezhaev. Scientists used Triton TX-114 solution with a mass concentration of 2.0 mg/dm3 as an absorption medium. The researchers performed flushing from surfaces using cloth tampons moistened with Triton TX-114 solution with a mass concentration of 2.0 mg/dm3. We determined the particle sizes in the samples using NanotracULTRA (Microtrac). Scientists found aluminum and nitrocellulose particles with sizes from 36 to 102 nm in the air of the working area and flushes from horizontal surfaces. The study of the fractional composition of RDX and aluminum powders of the ASD-1 brand showed the presence of nanoscale particles in them. Nanoscale dust particles pollute the air of the working area and solid horizontal surfaces at certain stages of the production of energy-intensive materials. There are nanoscale particles in the composition of powders of some standard components of formulations. Flushes from solid horizontal surfaces are an adequate qualitative indicator of the presence of nanoaerosols in the air of the working area.

Introductions: Pancasila is an absolute and important thing in the life of the nation and state in Indonesia. Therefore every Indonesian citizen is obliged to understand and implement the values contained in it. With this research, it is possible to determine the level of understanding of citizens towards Pancasila based on their social status in society. Method: The method in this research uses qualitative techniques by filling out questionnaires and interviews with respondents. Respondents involved in this research were dominated by students, health workers, housewives, and farmworkers. The age of the respondents in this research ranged from 17-52 years according to their profession. The research began with filling out questionnaires by respondents and several inter-views, the data obtained were processed to produce conclusions. After that, it can be used as a reference to instill an understanding of Pancasila in the community. Results: The results of this research based on questionnaires and interviews with respondents obtained satisfactory answers. In other words, this research shows the level of education is a major factor and social status is not something that can hinder the understanding and implementation of Pancasila. All the respondents were able to mention the content and form of implementation of Pancasila. Conclusion: From the results obtained, it can be concluded that all respondents involved have been able to understand the form and implementation of Pancasila. It can be interpreted, that this must be held firmly so that understanding of Pancasila does not fade in the future. Limitation: The research is limited to Indonesian citizens and the lack of respondents involved is a limitation in writing this research. So the conclusions obtained only come from filling out questionnaires and interviews with the respondents involved.
Proactive interference and the development of working memory

Working Memory (WM), the ability to maintain information in service to a task, is characterized by its limited capacity. Several influential models attribute this limitation in a large extent to proactive interference (Anderson & Neely, 1996; Bunting, 2006; Kane & Engle, 2000), the phenomenon that previously encoded, now-irrelevant information competes with relevant information (Keppel & Underwood, 1963). Here, we look back at the adult PI literature, spanning over sixty years, as well as recent results linking the ability to cope with PI to WM capacity (Endress & Potter, 2014; Kane & Engle, 2000). In early development, WM capacity is even more limited (Kaldy & Leslie, 2005; Simmering, 2012), yet an accounting for the role of PI has been lacking. Our Focus Article aims to address this through an integrative account: since PI resolution is mediated by networks involving the frontal cortex (particularly, the left inferior frontal gyrus) and the posterior parietal cortex (Badre & Wagner, 2005; Jonides & Nee, 2006), and since children have protracted development and less recruitment (Crone et al., 2006) of these areas, the increase in the ability to cope with PI (Kail, 2002; De Visscher & Noel, 2014) is a major factor underlying the increase in WM capacity in early development. Given this, we suggest that future research should focus on mechanistic studies of PI resolution in children. Finally, we note a crucial methodological implication: typical WM paradigms repeat stimuli from trial-to-trial, facilitating, inadvertently, PI and reducing performance; we may be fundamentally underestimating children’s WM capacity.
Modality Effects in Free Recall: A Retrieved-Context Account
Authors: Pazdera Jesse Kendall , Kahana Michael J.
Published: January 2022

The modality effect refers to the robust finding that memory performance differs for items presented aurally, as compared with visually. Whereas auditory presentation leads to stronger recency performance in immediate recall, visual presentation often produces better primacy performance (the inverse modality effect). To investigate and model these differences, we conducted two large-scale web-based immediate free recall experiments. In both experiments, participants studied visual and auditory word lists of varying lengths and rates of presentation. We observed typical modality and inverse modality effects, while also discovering that participants were more likely to initiate recall from recent items on auditory trials than on visual trials. However, modality effects persisted regardless of the first item recalled. Meanwhile, an analysis of intrusion errors revealed that participants were more likely on visual trials than on auditory trials to erroneously recall words from one list prior. Furthermore, words presented in the same modality as the present list intruded more often than those presented in a different modality. We next developed a retrieved-context account of the modality effect by fitting the Context Maintenance and Retrieval model to data across multiple list lengths. Through our simulations, we demonstrate that the modality effect can be explained by faster contextual drift and stronger context-to-item association formation during auditory presentation, relative to visual. Our modeling shows that modality effects can arise without hypothesizing distinct memory stores for recent and remote information. Finally, we propose that modality effects may derive primarily from the temporal dynamics of stimuli, rather than their modality.
Volition and “free will”
Authors: Seghezzi Silvia , Haggard Patrick
Published: January 2022

Philosophers have debated the “free will” for centuries, yet it is only in recent years that voluntary actions have become an object of investigation for cognitive neuroscience. This review begins by attempting a definition of volition (i.e., the mental state associated specifically with voluntary actions) that could be relevant for cognitive neuroscience. We then review the neuropsychology of volition. Alterations in voluntary behaviour in neurological and psychiatric patients first suggested the possibility that specific cognitive processes of volition have specific bases in the brain. These findings counter traditional dogmas that human volition is somehow ineffable, and instead suggest that voluntary actions depend on specific brain circuitry that is accessible to scientific investigation.The second part of the review focuses on the experimental psychology of volition. A number of studies have combined a systematic manipulation of experimental conditions, and recording of brain processes associated with voluntary action. We argue that this combination is most likely to identify the brain processes specifically associated with volition, and we therefore review these studies systematically. For example, several studies link the Readiness Potential of the EEG to preparatory conscious preplanning of actions. Further, a meta-analysis of neuroimaging studies (PET/ fMRI) reveals a distinctive pattern of activations for choosing one among many possible actions - a key element of volition. The medial frontal cortex appears to make a key contribution to both these biomarkers of volition.
Harmonicity of Sound Alters Roughness Perception

Multisensory integration refers to the integration of multiple senses by the nervous system. Auditory andtactile features are closely related senses as can be understood from the fact that adjectives such as soft,rough, and warm are used commonly for auditory and tactile features. Previous studies show that auditorycues play an important role to assess the roughness of a surface. Different characteristics of auditory cuessuch as amplitude and frequency may cause perceiving surface rougher or smoother. In this study, weinvestigate the effects of harmonic and inharmonic sounds on roughness perception to examine whetherauditory roughness will affect the tactile roughness perception while they are presented simultaneously.We expected the participants to perceive surfaces rougher while they listen to inharmonic sounds due toauditory roughness. We presented simultaneous and sequential harmonic and inharmonic sounds withthree sandpapers with different roughness levels (P100, P120, P 150 grit numbers) to the participants. Wefound that participants perceive sandpaper with the P120 grit number rougher while they listen tosimultaneous inharmonic sounds than simultaneous harmonic sounds. However, any effect of harmonicityon the sandpapers with P100 and P150 grit numbers was not observed. We suggest that auditoryroughness may enhance tactile roughness perception for surfaces with particular roughness levels,possibly when the roughness estimation from the tactile sense remains ambiguous.

Objective: The aim of this work was to examine the fidelity and validity of an aviation simulation using eye tracking. Background: Commercial head-mounted virtual reality (VR) systems offer a convenient and cost-effective alternative to existing aviation simulation (e.g., for refresher exercises). We performed pre-implementation testing of a novel aviation simulation, designed for head-mounted VR, to determine its fidelity and validity as a training device. Method: Eighteen airline pilots, with varying levels of flight experience, completed a sequence of training ‘flows’. Self-reported measures of presence and workload and users’ perceptions of fidelity were taken. Pilots’ eye movements and performance were recorded to determine whether more experienced pilots showed distinct performance and eye gaze profiles in the simulation, as they would in the real-world. Results: Real-world expertise correlated with eye gaze patterns characterised by fewer, but longer, fixations and a scan path that was more structured and less random. Multidimensional scaling analyses also indicated differential clustering of strategies in more versus less experienced pilots. Subjective ratings of performance, however, showed little relationship with real-world expertise or eye movements. Conclusion: We adopted an evidence-based approach to assessing the fidelity and validity of a VR flight training tool. Pilot reports indicated the simulation was realistic and potentially useful for training, while direct measurement of eye movements was useful for establishing construct validity and psychological fidelity of the simulation.
