Physiology, Vitalism, and the Contest for Body and Soul in the Antebellum United States.

In the early nineteenth century, physiology became an increasingly popular and powerful science in the United States. Religious controversy over the nature of human vitality animated much of this interest. On one side of these debates stood Protestant apologists who wedded an immaterialist vitalism to their belief in an immaterial, immortal soul - and therefore to their dreams of a Christian republic. On the other side, religious skeptics argued for a materialist vitalism that excluded anything immaterial from human life, aspiring thereby to eliminate religious interference in the progress of science and society. Both sides hoped that by claiming physiology for their vision of human nature they might direct the future of religion in the US. Ultimately, they failed to realize these ambitions, but their contest posed a dilemma late nineteenth-century physiologists felt compelled to solve: how should they comprehend the relationship between life, body, and soul? Eager to undertake laboratory work and leave metaphysical questions behind, these researchers solved the problem by restricting their work to the body while leaving spiritual matters to preachers. In attempting to escape the vitalism and soul questions, late nineteenth-century Americans thus created a division of labor that shaped the history of medicine and religion for the following century.

Uma reflexão epistemológica sobre a consulta homeopática / An epistemological reflection on homeopathic consultation

A consulta médica tem um lugar especial no tratamento homeopático. Diferente do aprendido durante a formação hegemônica, em que as técnicas semiológicas se concentram na busca de sintomas para realizar o diagnóstico clínico, e daí estabelecer um tratamento para patologias pré-classificadas com protocolos pré-existentes, na Homeopatia é preciso reconfigurar alguns conceitos, que começam no ato da consulta. Na abordagem homeopática, onde a visão mecanicista deve ser acoplada ao paradigma vitalista, busca-se padrões e causas relacionados aos sintomas, acrescentando ao diagnóstico clínico também a individualidade, entre outros diagnósticos, para tratamento de forma integrada, em busca da cura ideal. O objetivo deste texto é analisar a consulta homeopática de acordo com as peculiaridades da racionalidade homeopática, construída por Samuel Hahnemann, em consonância com a epistemologia da complexidade, que embasa muitas outras áreas de conhecimentos na contemporaneidade, estudada por Edgar Morin.

Medical consultation has a special place in homeopathic treatment. Unlike what was learned during hegemonic formation, in which semiological techniques focus on searching for symptoms to make a clinical diagnosis, and then establishing a treatment for pre-classified pathologies with pre-existing protocols, in Homeopathy it is necessary to reconfigure some concepts, which begin at the time of consultation. In the homeopathic approach, where the mechanistic vision must be coupled with the vitalist paradigm, patterns and causes related to symptoms are sought, adding individuality to the clinical diagnosis, among other diagnoses, for integrated treatment, in search of the ideal cure. The objective of this text is to analyze homeopathic consultation according to the peculiarities of homeopathic rationality, constructed by Samuel Hahnemann, in line with the epistemology of complexity, which underpins many other areas of knowledge in contemporary times, studied by Edgar Morin.

O poder sobre a vida: os corpos regidos pela prática biomédica versus corpos de intensidades / The power over life: bodies governed by biomedical practice versus intensity bodies

Neste artigo, discuto a questão da materialidade organicista do corpo contra um corpo de intensidades. De acordo com Separavich e Canesqui (2010), os estudos de Marcel Mauss (2003 [1934]) e Margaret Mead (2000 [1935]) "revelou que, embora se possa atribuir uma materialidade universal ao corpo, definições, disposições corporais e seus significados são múltiplos. Como resultado dessa heterogeneidade nas formas de conceber corpo, as concepções do que seja saúde e doença também múltiplas tradições" (p. 251). De acordo com Cecil G. Helman (1994) para "os membros de todas as sociedades, o corpo humano é mais do que um simples organismo físico oscilando entre a saúde e a doença. É também o foco de um conjunto de crenças sobre seu significado social e psicológico, estrutura e funcionamento. A expressão 'imagem corporal' é usada para descrever todas as maneiras pelas quais um indivíduo conceitua e experimenta seu próprio corpo, consciente ou inconscientemente" (p. 30), variando com cada sociedade e momento histórico em que se definem: incluem crenças sobre a forma e o tamanho ideal do corpo, crenças sobre sua estrutura e crenças sobre suas funções. Pretendo refletir sobre o corpo, trazendo alguns elementos históricos para chamar a atenção para a ocorrência de certas condições ­ conhecimento médico e outros aspectos sócio-históricos ­ entrelaçada com a produção de práticas e intervenções médicas, no corpo, assim como no governo da vida, com a intenção de chamar a atenção para as práticas médicas integrativas que são a partir de uma visão do corpo de intensidades.

In this article, I discuss the issue of the organicist materiality of the body versus a body of intensities. According to Separavich and Canesqui (2010), the studies of Marcel Mauss (2003 [1934]) and Margaret Mead (2000 [1935]) "revealed that, although a universal materiality can be attributed to the body, definitions, bodily dispositions and their meanings are manifold. As a result of this heterogeneity in the ways of conceiving the body, the conceptions of what health and disease are also have multiple traditions" (p. 251). According to Cecil G. Helman (1994) for "the members of all societies, the human body is more than a simple physical organism oscillating between health and disease. It is also the focus of a set of beliefs about its social and psychological meaning, structure and functioning. The expression 'body image' is used to describe all the ways in which an individual conceptualizes and experiences his own body, consciously or unconsciously" (p. 30), varying with each society and historical moment in which they are defined: they include beliefs about ideal body shape and size, beliefs about its internal structure, and beliefs about its functions. I intend to reflect on the body, bringing some historical elements to draw attention to the occurrence of certain conditions - medical knowledge and other socio-historical aspects - intertwined with the production of medical practices and interventions, in the body, as well as in the government of life, with the intention of drawing attention to integrative medical practices that are based on a vision of the body of intensities.

Lógica histórica da medicina e a homeopatia / The historical logic of medicine and homeopathy

Este artigo baseia-se na tese de que a teoria homeopática está originalmente orientada por um vitalismo de caráter hermenêutico, isto é, assume que a positividade dos fenômenos com que lida é sempre dependente de uma totalidade compreensiva (totalidade vital), singularizada em cada situação individual e somente acessível por meio das narrativas dos pacientes. O objetivo do estudo foi compreender as relações entre estas concepções vitalistas e o lugar dos procedimentos compreensivo- -interpretativos na propedêutica e terapêutica propostas pela teoria homeopática, as quais podem apontar alternativas para estabelecer as suas bases de validação. Trata-se de um estudo qualitativo, baseado na análise documental de textos canônicos da homeopatia, especialmente a obra de Hahnemann, e entrevistas em profundidade com homeopatas que combinam atividade clínica com pesquisa e docência na área (formadores de opinião). A metodologia foi instruída pela Hermenêutica Filosófica e pela Epistemologia Histórica, sendo o substrato discursivo (escrito e falado) trabalhado de modo não-formalista, buscando-se identificar e interpretar livremente eixos narrativos e núcleos de significado julgados relevantes. A discussão voltou-se fundamentalmente para a recuperação dos principais movimentos históricos de conformação do paradigma vitalista na homeopatia, o cotejamento desse desenvolvimento com a adoção de procedimentos semiológicos de caráter compreensivo-interpretativo e as implicações desse "vitalismo da palavra" para as concepções homeopáticas contemporâneas. O trabalho aponta para a positividade e produtividade do trabalho com a linguagem e as narrativas no âmbito de uma homeopatia entendida como uma "medicina do sujeito", e sugere aprofundamentos na direção hermenêutico- -filosófica como alternativa para o adensamento conceitual e para o aperfeiçoamento dos processos de validação do saber e da prática da homeopatia.

Homeopathic medicine is a socially validated practice, progressively incorporated into the institutional health care scheme, including the public health system. However, the issue of the fundamentals of this therapeutic, of its scientific validation, remains outstanding. In the sense of responding to this demand for validation, there is a need for research methodologies. that allow for accurate investigations, suitable for the concepts of health, illness and therapeutics that are intrinsic to the homeopathic rational. This paper is based on the notion that homeopathic theory is originally guided by a vitalism of hermeneutical character, that. is, it assumes that the positivity of phenomena with which it deals, is always dependent on the comprehensive totality (vital totality), specific to each individual situation and accessible only by means of the patients´ narratives. The study's purpose was to understand the relations between these vitalist concepts and the place of comprehensive-interpretative procedures in the propedeutics and therapeutics proposed by the homeopathic medicine that may point out to alternatives to establish its validation bases. This is qualitative research, based on the documentary analysis of homeopathy canonic texts, especially the work of Hahnemann, and originally n-depth interviews with homeopaths that combine clinic activity and education in the area (opinion makers). The methodology was instructed by Philosophic. Hermeneutics and by Historic Epistemology, and the layer subjacent to the discourse (written and spoken) effected in a non-formal manner, searching for the free identification. And interpretation of the narrative axes and core meanings that were deemed significant. The discussion was basically focused on the recovery of the major historical movements related. To the development of the vitalist paradigm in homeopathy, the comparison of this development with the adoption of semiologic procedures of comprehensive- -interpretative character and the implications of this "vitalism of the word" to the contemporary homeopathic concepts. The paper points out to the positivity and productivity of the work on language and narratives in the domain of a homeopathy understood as "medicine of the subject" and suggests deeper studies in the hermeneutical-philosophical direction as an alternative for the concept densification and for the improvement of validation processes of knowledge and practice of homeopathy.

Notas para decolonizar os estudos transpessoais no brasil: contribuições do pluriperspectivismo participativo / Notes for decolonizing transpersonal studies in brazil: contributions of participatory pluriperspectivism / Apuntes para la decolonización de los estudios transpersonales en brasil: aportes del pluriperspectivismo participativo

O campo dos estudos transpessoais tem avançado em diversas áreas no Brasil. Comemorou seus 40 anos com uma inserção ativa nas Instituições de Ensino Superior (IES) e uma ampliação de núcleos formativos e apoiadores de ensino, pesquisa e ações sociais, além de diálogos com o Sistema de Conselhos de Psicologia. Desafios são apresentados a partir do levantamento de uma série de questões importantes e ignoradas dentro da Psicologia Transpessoal no Brasil. Apresentamos o pluriperspectivismo participativo como possibilidade de decolonizar as matrizes eurocêntricas e estadunidenses, que dão suporte ao pensamento transpessoal brasileiro, buscando honrar nossas raízes históricas e incluir outras epistemologias e ontologias, que dão continuidade à crítica à lógica cartesiana moderna. Indicamos uma breve agenda de notas temáticas que carecem de um processo decolonizador no campo transpessoal: a) crítica às perspectivas de um pensamento hegemônico, em termos globais por meio da dominação Norte-Sul ou no campo das relações sociais; b) revisão das formas de "centrocentrismo"; c) questionamento da noção de universalismo das ciências e da ética; d) aprofundamento da análise crítica da supremacia restritiva da racionalidade formal técnico-científica em relação às formas de subjetividade, de vivências holísticas e integradoras e de valorização do corpo; e) revisão da noção de sujeito moderno desprovida da cocriação do humano com a comunidade, a história, a natureza e o cosmos.(AU)

The field of transpersonal studies has advanced in several areas in Brazil. It celebrated its 40th anniversary with an active insertion in Higher Education Institutions (HEI) and an expansion of training centers and supporters of teaching, research, and social actions, in addition to dialogues with the System of Councils of Psychology. Challenges are presented based on a survey of a series of important and ignored issues within Transpersonal Psychology in Brazil. We present participatory pluriperspectivism as a possibility to decolonize the Eurocentric and North American matrices that support Brazilian transpersonal thought, seeking to honor our historical roots and include other epistemologies and ontologies, which continue the critique of modern Cartesian logic. We indicate a brief agenda of thematic notes that lack a decolonizing process in the transpersonal field: a) criticism of the perspectives of a hegemonic thought, whether in global terms via North-South domination or in the field of social relations; b) review of the forms of "centrocentrism"; c) questioning of the notion of universalism of science and ethics; d) deepening of the critical analysis of the restrictive supremacy of the technical-scientific formal rationality in relation to the forms of subjectivity, of holistic and integrative experiences, and of valuing the body; e) review of the notion of the modern subject devoid of the co-creation of the human with the community, the history, the nature, and the cosmos.(AU)

William Preyer and the origin of the term biomechanics / William Preyer y el origen del término Biomecánica

Many Biomechanics texts and courses begin with a historical introduction. This usually describes the contributions of a large number of people who, over many centuries, have been fundamental to the development of this science. In these presentations it is often stated that the term Biomechanik (Biomechanics) appears to have been used for the first time in 1887 by Dr. Moriz Benedikt, in Über Mathematische Morphologie und Biomechanik. However, this term was previously used by the physiologist William Preyer in 1873 and 1883. In this short article, we show these first mentions and frame them in the context of other terms, Biostatik (Biostatics) and Biodynamik (Biodynamics), used at that time. Finally, as a secondary result of the research, we found what could be the first textbook that specifically addresses Biomechanics as a new object of scientific knowledge.(AU)

Missing Part of Vitalism: Information.

No Abstract Available.

The third-way third wave and the enduring appeal of bioexceptionalism.

We may induce from a longue durée examination of Anglo-American History of Biology that the impulse to reject reduc - tionism persists and will continue to percolate cyclically. This impulse I deem "bioexceptionalism": an intuition, stance, attitude, or activating metaphor that the study of living beings requires explanations in addition to exclusively bottom-up causal explanations and the research programs constructed upon that bottom-up philosophical foundation by non-organismal biologists, biochemists, and biophysicists - the explanations, in other words, that Wadding - ton (1977) humorously termed the "Conventional Wisdom of the Dominant Group, or cowdung." Bioexceptionalism might indicate an ontological assertion, like vitalism. Yet most often in the last century, it has been defined by a variety of methodological or even sociological positions. On three occasions in the interval from the late nineteenth century to the present, a small but significant group of practicing biologists and allies in other research disciplines in the UK and US adopted a species of bioexceptionalism, rejecting the dominant explanatory philosophy of reductionistic mechanism. Yet they also rejected the vitalist alternative. We can refer to their subset of bioexceptionalism as a "Third-Way" approach, though participants at the time called it by a variety of names, including "organicism." Today's appeals to a Third-Way are but the latest eruption of this older dissensus and retain at least heuristic value apart from any explanatory success.

Locating hygienic medicine within the intellectual history of hygiene: cases of E. W. Lane and T. R. Allinson.

Nineteenth century hygiene might be a confusing concept. On the one hand, the concept of hygiene was gradually becoming an important concept that was focused on cleanliness and used interchangeably with sanitation. On the other hand, the classical notions of hygiene rooted in the Hippocratic teachings remained influential. This study is about two attempts to newly theorise such a confusing concept of hygiene in the second half of the century by Edward. W. Lane and Thomas R. Allinson. Their works, standing on the borders of self-help medical advice and theoretical treatises on medical philosophies, were not exactly scholarly ones, but their medical thoughts - conceptualised as hygienic medicine - show a characteristically holistic medical view of hygiene, a nineteenth-century version of the reinterpretation of the nature cure philosophy and vitalism. However, the aim of this study is to properly locate their conceptualisations of hygienic medicine within the historical context of the second half of the nineteenth century rather than to simply introduce the medical ideas in their books. Their views of hygiene were distinguished not only from the contemporary sanitary approach but also from similar attempts by contemporary orthodox and unorthodox medical doctors. Through a chronological analysis of changes in the concept of hygiene and a comparative analysis of these two authors' and other medical professionals' views of hygiene, this paper aims to help understand the complicated picture of nineteenth-century hygiene, particularly during the second half of the century, from the perspective of medical holism and reductionism.

From Organismic Biology as History and Philosophy to the History and Philosophy of Biology-the Work of Hans-Jörg Rheinberger in the German Context.

In this paper, I ask about the broader context of the history and philosophy of biology in the German-speaking world as the place in which Hans-Jörg Rheinberger began his work. Three German philosophical traditions-neo-Kantianism, phenomenology, and Lebensphilosophie-were interested in the developments and conceptual challenges of the life sciences in the late nineteenth and early twentieth centuries. Their reflections were taken up by life scientists under the terms theoretische Biologie (theoretical biology) and allgemeine Biologie (general biology), i. e., for theoretical and methodological reflections. They used historical and philosophical perspectives to develop vitalistic, organicist, or holistic approaches to life. In my paper, I argue that the resulting discourse did not come to an end in 1945. Increasingly detached from biological research, it formed an important context for the formation of the field of history and philosophy of biology. In Rheinberger's work, we can see the "Spalten" and "Fugen"-the continuities and discontinuities-that this tradition left there.

Vitalism, Holism, and Metaphorical Dynamics of Hans Spemann's "Organizer" in the Interwar Period.

This paper aims to provide a fresh historical perspective on the debates on vitalism and holism in Germany by analyzing the work of the zoologist Hans Spemann (1869-1941) in the interwar period. Following up previous historical studies, it takes the controversial question about Spemann's affinity to vitalistic approaches as a starting point. The focus is on Spemann's holistic research style, and on the shifting meanings of Spemann's concept of an organizer. It is argued that the organizer concept unfolded multiple layers of meanings (biological, philosophical, and popular) during the 1920s and early 1930s. A detailed analysis of the metaphorical dynamics in Spemann's writings sheds light on the subtle vitalistic connotations of his experimental work. How Spemann's work was received by contemporary scientists and philosophers is analyzed briefly, and Spemann's holism is explored in the broader historical context of the various issues about reductionism and holism and related methodological questions that were so prominently discussed not only in Germany in the 1920s.

Reflections on the fundamental nature of homeopathic potencies: Plasma, Langmuir Adsorption and Vitalism

There is a pressing need to develop methods and approaches that will identify the fundamental nature of homeopathic potencies. Aims: To bring together recent basic research on potencies, especially that using solvatochromic dyes, and to supplement these results with reliable observations made by Hahnemann and his contemporaries from the very beginnings of homeopathy, together with a detailed examination of the process of trituration and succussion coupled to dilution, in order to significantly limit the number of possible explanations as to the identity of potencies. Methodology: A mixture of lab based and literature studies such that as far as possible all verified and substantiated observations about homeopathic potencies have been examined. Results and Discussion: An understanding of the fundamental nature of homeopathic potencies that includes all known and accepted observations (in vitro, in vivoand clinical) is not realistic without embracing hypotheses involving the emergent properties of complex systems and in particular, vitalistic concepts. Using a vitalistic model it is possible to explain a wide range of seemingly unrelated phenomena -such as the polarising effect of potencies on solvatochromic dyes, the ability to use a range of materials such as water, lactose and cellulose as carriers of potencies, the administering of potencies by olfaction, the antidoting effect of camphor on potency action, the non-linear dependence of potency strength on volume as well as succussion level, the oscillatory behaviour of potencies and experimenter/observer/practitioner effects. Conclusion: A hypothesis in which homeopathic potencies can be seen as self-actuating and autonomous plasma generated by trituration and/or succussion and carried according to Langmuir adsorption models fits the known observations about potencies.

"What is Dead May Not Die": Locating Marginalized Concepts Among Ordinary Biologists.

Historians and biologists identify the debate between mechanists and vitalists over the nature of life itself with the arguments of Driesch, Loeb, and other prominent voices. But what if the conversation was broader and the consequences deeper for the field? Following the suspicions of Joseph Needham in the 1930s and Francis Crick in the 1960s, we deployed tools of the digital humanities to an old problem in the history of biology. We analyzed over 31,000 peer-reviewed scientific papers and learned that bioexceptionalism participated in a robust discursive landscape throughout subfields of the life sciences, occupied even by otherwise unknown biologists.

Reductionism, Vitalism, and Holism.

The reductionist strategy, adopted by physics and chemistry, which was based on the effort to reduce the concepts necessary for the statement of scientific explanations to a minimum, was attractive to those who worked in the biomedical field. On the other hand, the vitalistic point of view opposed mechanism, believing that there were processes in living organisms that do not obey the laws of physics and chemistry. Finally, the holistic approach is focused on the evidence that the organized whole is almost always much more than the sum of its parts, and have led to direct attention to emerging qualities in a highly organized system which is a living being.

Selecting Instruments for Measuring the Clinical Learning Environment of Medical Education: A 4-Domain Framework.

Learning environments shape the experiences of learners and practitioners, making them an important component of program evaluation. However, educators find it challenging to decide whether to measure clinical learning environments with existing instruments or to design their own new instrument and, if using an existing instrument, which to choose. To assist educators with these decisions, the authors compared clinical learning environment instruments based on their characteristics, underlying constructs, and degree to which items reflect 4 domains (personal, social, organizational, material) from a recently developed model for conceptualizing learning environments in the health professions. Building on 3 prior literature reviews as well as a literature search, the authors identified 6 clinically oriented learning environment instruments designed for medical education. They collected key information about each instrument (e.g., number of items and subscales, conceptual frameworks, operational definitions of the learning environment) and coded items from each instrument according to the 4 domains. The 6 instruments varied in number of items, underlying constructs, subscales, definitions of clinical learning environment, and domain coverage. Most instruments focused heavily on the organizational and social domains and less on the personal and material domains (half omitted the material domain entirely). The variations in these instruments suggest that educators might consider several guiding questions. How will they define the learning environment and which theoretical lens is most applicable (e.g., personal vitality, sociocultural learning theory)? What aspects or domains of the learning environment do they most wish to capture (e.g., personal support, social interactions, organizational culture, access to resources)? How comprehensive do they want the instrument to be (and correspondingly how much time do they expect people to devote to completing the instrument and how frequently)? Whose perspective do they wish to evaluate (e.g., student, resident, fellow, attending, team, patient)? Each of these considerations is addressed.

Concepção vitalista de Samuel Hahnemann / Vitalist conception of Samuel Hahnemann

Estando a homeopatia fundamentada no modelo médico vitalista, conceitos como força vital, mente, alma, espírito, etc., referentes à natureza imaterial humana, são frequentemente citados, tornando-se indispensável sua compreensão. Fundamentado nas obras de Samuel Hahnemann, fundador da homeopatia, incluindo seus escritos menores e cartas, essa obra busca esclarecer essas concepções, no intuito de dissolver confusões doutrinárias. No referido estudo, fica claro o conceito de 'força vital instintiva e irracional', análoga à 'vis medicatrix naturae' hipocrática, formando um composto substancial com o corpo físico e de natureza distinta do espírito inteligente. Como outra entidade distinta das anteriores, Hahnemann também cita a mente, sede da alma, como 'órgãos físicos quase não-materiais, de mais alta hierarquia', atribuindo ao psiquismo humano a maior influência no binômio saúde-doença, referindo-se à moral e à ética como fatores preventivos e curativos das enfermidades que afetam a humanidade. Critica a escolástica e o excesso de especulações metafísicas, afastando-se de qualquer corrente filosófica ou religiosa, brindando-nos com conceitos espiritualistas universalistas dentro dos princípios morais e éticos, engrandecendo ainda mais sua obra e demonstrando ser um observador livre de preconceitos. Para Hahnemann, o corpo físico forma uma unidade substancial com o princípio vital, e não com a alma, sendo comandado pelo espírito inteligente que nele habita. A mente, como órgão psíquico, assume importante papel na relação entre essas entidades que compõe o ser humano. (AU)

Since homeopathy is based on the vitalist medical model, concepts such as vital force, mind, soul, spirit, etc., referring to the immaterial human nature, are frequently cited, making their understanding indispensable. Based on the works of Samuel Hahnemann, founder of homeopathy, including his minor writings and letters, this work seeks to clarify these conceptions, in order to dissolve doctrinal confusions. In this study, the concept of 'instinctive and irrational vital force', analogous to the Hippocratic 'vis medicatrix naturae', becomes clear, forming a substantial compound with the physical body and a nature distinct from the intelligent spirit. As another entity distinct from the previous ones, Hahnemann also mentions the mind, seat of the soul, as 'physical organs almost non-material, of higher hierarchy', attributing to the human psyche the greatest influence in the binomial health-disease, referring to the moral and ethics as preventive and curative factors for diseases that affect humanity. He criticizes scholasticism and the excess of metaphysical speculations, moving away from any philosophical or religious current, offering us universalistic spiritualist concepts within moral and ethical principles, further enhancing his work and demonstrating that he is a prejudice-free observer. For Hahnemann, the physical body forms a substantial unity with the vital principle, and not with the soul, being commanded by the intelligent spirit that in him dwells. The mind, as a psychic organ, assumes an important role in the relationship between these entities that make up the human being. (AU)

Inconsistencies between mental fatigue measures under compensatory control theories / Inconsistencias entre medidas de fatiga mental bajo las teorías del control compensatorio

Mental fatigue has traditionally been defined as a condition of reduced cognitive efficiency and performance, accompanied by a subjective feeling of fatigue. Even though we could expect to find associations between the three defining characteristic of mental fatigue (performance impairment, physiological deactivation and subjective fatigue), research has shown that the emergence of inconsistencies between measures is more frequent than one might expect: people proved capable of maintaining adequate performance levels even after having declared themselves fatigued. This could be explained under the compensatory control mechanism models, which state that humans are able to provide additional resources under demanding conditions, but only at the expense of psychophysiological cost and subjective fatigue. We tested this explanation by manipulating task complexity and time performing a simulated air-traffic control task. We collected psychophysiological, performance and subjective data. A decrease in pupil size was seen in the low-aircraft-density condition, while pupil size remained constant in the high-aircraft-density condition. Participants' task performance was optimal in both conditions, though they showed an increase in subjective feelings of fatigue, especially in the high-complexity task condition. Thus, complexity seemed to trigger compensatory mechanisms, which reallocated extra resources that physiologically activated participants in order to deal with a higher complexity task, whereas subjective fatigue could be acting as a signal to the organism of impending resource depletion. Our findings support compensatory control theories and offer an explanation of inconsistencies between fatigue measures. Further research on compensatory mechanisms is needed to enable better management of fatigue effects to prevent work-related accidents

Tradicionalmente, la fatiga mental ha sido definida como una condición de reducción en los niveles de eficiencia cognitiva y rendimiento, acompañada de una sensación subjetiva de fatiga mental. A pesar de que podríamos esperar encontrar asociaciones (convergencia) entre las tres características definitorias de la fatiga mental (deterioro en el rendimiento, reducción en los niveles de activación fisiológica y surgimiento de fatiga subjetiva), la literatura ha revelado que la aparición de inconsistencias (divergencia) entre las medidas de fatiga es más frecuente de lo esperado: la gente se muestra capaz de mantener niveles adecuados de rendimiento a pesar de haber declarado encontrarse fatigados. Esto puede explicarse a partir de los modelos del mecanismo de control compensatorio, los cuales afirman que los seres humanos son capaces de proveerse con recursos adicionales bajo condiciones de elevada demanda cognitiva, únicamente a expensas de un coste psicofisiológico y del surgimiento de la sensación subjetiva de fatiga mental. En el presente estudio, ponemos a prueba esta explicación manipulando el tiempo y la complejidad de una tarea de simulación de control de tráfico aéreo. Recabamos datos psicofisiológicos, de rendimiento y subjetivos. Nuestros resultados desvelan una disminución del diámetro pupilar en la condición de baja densidad de tráfico aéreo, en tanto que se mantiene constante en la condición de alta densidad. El nivel de rendimiento de los participantes resultó ser óptimo en ambas condiciones, a pesar de que se aprecia un incremento lineal en los niveles de fatiga subjetiva, especialmente en la condición de alta complejidad. Así, la complejidad parece activar el mecanismo compensatorio, el cual provee al organismo con recursos adicionales que mantienen fisiológicamente activados a los participantes de la condición de alta densidad de tráfico al objeto de hacer frente a una tarea de mayor dificultad, mientras que la fatiga subjetiva podría estar actuando como una señal del organismo para impedir el agotamiento de los recursos cognitivos. Nuestros hallazgos apoyan las teorías del control compensatorio y ofrecen una posible explicación sobre algunas inconsistencias entre las medidas de fatiga mental. La ciencia necesita seguir investigando el fenómeno del mecanismo compensatorio para favorecer la gestión de los efectos de la fatiga mental y prevenir los accidentes laborales

Measurement invariance of the moral vitalism scale across 28 cultural groups.

Moral vitalism refers to a tendency to view good and evil as actual forces that can influence people and events. The Moral Vitalism Scale had been designed to assess moral vitalism in a brief survey form. Previous studies established the reliability and validity of the scale in US-American and Australian samples. In this study, the cross-cultural comparability of the scale was tested across 28 different cultural groups worldwide through measurement invariance tests. A series of exact invariance tests marginally supported partial metric invariance, however, an approximate invariance approach provided evidence of partial scalar invariance for a 5-item measure. The established level of measurement invariance allows for comparisons of latent means across cultures. We conclude that the brief measure of moral vitalism is invariant across 28 cultures and can be used to estimate levels of moral vitalism with the same precision across very different cultural settings.
