The role of domain-general cognitive resources in children's construction of a vitalist theory of biology.

Some episodes of learning are easier than others. Preschoolers can learn certain facts, such as "my grandmother gave me this purse," only after one or two exposures (easy to learn; fast mapping), but they require several years to learn that plants are alive or that the sun is not alive (hard to learn). One difference between the two kinds of knowledge acquisition is that hard cases often require conceptual construction, such as the construction of the biological concept alive, whereas easy cases merely involve forming new beliefs formulated over concepts the child already has (belief revision, a form of knowledge enrichment). We asked whether different domain-general cognitive resources support these two types of knowledge acquisition (conceptual construction and knowledge enrichment that supports fast mapping) by testing 82 6-year-olds in a pre-training/training/post-training study. We measured children's improvement in an episode involving theory construction (the beginning steps of acquisition of the framework theory of vitalist biology, which requires conceptual change) and in an episode involving knowledge enrichment alone (acquisition of little known facts about animals, such as the location of crickets' ears and the color of octopus blood). In addition, we measured children's executive functions and receptive vocabulary to directly compare the resources drawn upon in the two episodes of learning. We replicated and extended previous findings highlighting the differences between conceptual construction and knowledge enrichment, and we found that Executive Functions predict improvement on the Vitalism battery but not on the Fun Facts battery and that Receptive Vocabulary predicts improvement the Fun Facts battery but not on the Vitalism battery. This double dissociation provides new evidence for the distinction between the two types of knowledge acquisition, and bears on the nature of the learning mechanisms involved in each.

Can the inherence heuristic explain vitalistic reasoning?

Inherence is an important component of psychological essentialism. By drawing on vitalism as a way in which to explain this link, however, the authors appear to conflate causal explanations based on fixed features with those based on general causal forces. The disjuncture between these two types of explanatory principles highlights potential new avenues for the inherence heuristic.

The Lucretian swerve: the biological basis of human behavior and the criminal justice system.

It is widely believed, at least in scientific circles, that living systems, including mankind, obey the natural physical laws. However, it is also commonly accepted that man has the capacity to make "free" conscious decisions that do not simply reflect the chemical makeup of the individual at the time of decision--this chemical makeup reflecting both the genetic and environmental history and a degree of stochasticism. Whereas philosophers have discussed for centuries the apparent lack of a causal component for free will, many biologists still seem to be remarkably at ease with this notion of free will; and furthermore, our judicial system is based on such a belief. It is the author's contention that a belief in free will is nothing other than a continuing belief in vitalism--something biologists proudly believe they discarded well over 100 years ago.

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.

Vitalism, purpose and superstition.

Developmental studies have shown that children assign purpose to objects more liberally than adults, and that they explain biological processes in terms of vitalistic causality. This study tested the hypothesis that similar misconceptions can be found among superstitious adults. The results from 116 superstitious and 123 sceptical individuals showed that more than sceptics, superstitious individuals attributed purpose to objects, and explained biological processes in terms of organ intentionality and energy transmission. In addition, they thought of energy as a vital force, attributing life and mental properties to it. These conceptual confusions were positively associated to all types of superstitions as well as belief in alternative medicine. The results support the argument that category mistakes and ontological confusions underlie superstitious and vitalistic thinking.

Tone as a health concept: An analysis.

STUDY DESIGN: Concept analysis. INTRODUCTION: This paper is a report on the analysis of the concept of tone in chiropractic. PURPOSE: The purpose of this paper is to clarify the concept of tone as originally understood by Daniel David Palmer from 1895 to 1914 and to monitor its evolution over time. METHODS: Data was sourced from Palmer's original work, published between 1895 and 1914. A literature search from 1980 to 2016 was also performed on the online databases CINHAL, PubMed and Scopus with key terms including 'tone', 'chiropractic', 'Palmer', 'vitalism', 'health', 'homeostasis', 'holism' and 'wellness'. Finally hand-searches were conducted through chiropractic books and professional literature from 1906 to 1980 for any references to 'tone'. Rodgers' evolutionary method of analysis was used to categorise the data in relation to the surrogates, attributes, references, antecedents and consequences of tone. RESULTS: A total of 49 references were found: five from publications by Palmer; three from the database searches, and; the remaining 41 from professional books, trade journals and websites. MAJOR CONCLUSIONS: There is no clear interpretation of tone in the contemporary chiropractic literature. Tone is closely aligned with functional neurology and can be understood as an interface between the metaphysical and the biomedical. Using the concept of tone as a foundation for practice could strengthen the identity of the chiropractic profession.

Scientism and Pseudoscience: A Philosophical Commentary.

The term "scientism" is used in a variety of ways with both negative and positive connotations. I suggest that some of these uses are inappropriate, as they aim simply at dismissing without argument an approach that a particular author does not like. However, there are legitimate negative uses of the term, which I explore by way of an analogy with the term "pseudoscience." I discuss these issues by way of a recent specific example provided by a controversy in the field of bioethics concerning the value, or lack thereof, of homeopathy. I then frame the debate about scientism within the broader context of C.P. Snow's famous essay on the "two cultures."

Impure placebo is a useless concept.

Placebos are allegedly used widely in general practice. Surveys reporting high level usage, however, have combined two categories, 'pure' and 'impure' placebos. The wide use of placebos is explained by the high level usage of impure placebos. In contrast, the prevalence of the use of pure placebos has been low. Traditional pure placebos are clinically ineffective treatments, whereas impure placebos form an ambiguous group of diverse treatments that are not always ineffective. In this paper, we focus on the impure placebo concept and demonstrate problems related to it. We also show that the common examples of impure placebos are not meaningful from the point of view of clinical practice. We conclude that the impure placebo is a scientifically misleading concept and should not be used in scientific or medical literature. The issues behind the concept, however, deserve serious attention in future research.

Vitalism in naive biological thinking.

Vitalism is the belief that internal bodily organs have agency and that they transmit or exchange a vital force or energy. Three experiments investigated the use of vitalistic explanations for biological phenomena by 5- and 10-year-old English-speaking children and adults, focusing on 2 components: the notion that bodily organs have intentions and the notion that some life force or energy is transmitted. The original Japanese finding of vitalistic thinking was replicated in Experiment 1 with English-speaking 5-year-olds. Experiment 2 indicated that the more active component of vitalism for these children is a belief in the transfer of energy during biological processes, and Experiment 3 suggested an additional, albeit lesser, role for organ intentionality. A belief in vital energy may serve a causal placeholder function within a naive theory of biology until a more precisely formulated mechanism is known.

The organism as ontological go-between: hybridity, boundaries and degrees of reality in its conceptual history.

The organism is neither a discovery like the circulation of the blood or the glycogenic function of the liver, nor a particular biological theory like epigenesis or preformationism. It is rather a concept which plays a series of roles--sometimes overt, sometimes masked--throughout the history of biology, and frequently in very normative ways, also shifting between the biological and the social. Indeed, it has often been presented as a key-concept in life science and the 'theorization' of Life, but conversely has also been the target of influential rejections: as just an instrument of transmission for the selfish gene, but also, historiographically, as part of an outdated 'vitalism'. Indeed, the organism, perhaps because it is experientially closer to the 'body' than to the 'molecule', is often the object of quasi-affective theoretical investments presenting it as essential, sometimes even as the pivot of a science or a particular approach to nature, while other approaches reject or attack it with equal force, assimilating it to a mysterious 'vitalist' ontology of extra-causal forces, or other pseudo-scientific doctrines. This paper does not seek to adjudicate between these debates, either in terms of scientific validity or historical coherence; nor does it return to the well-studied issue of the organism-mechanism tension in biology. Recent scholarship has begun to focus on the emergence and transformation of the concept of organism, but has not emphasized so much the way in which organism is a shifting, 'go-between' concept-invoked as 'natural' by some thinkers to justify their metaphysics, but then presented as value-laden by others, over and against the natural world. The organism as go-between concept is also a hybrid, a boundary concept or an epistemic limit case, all of which partly overlap with the idea of 'nomadic concepts'. Thereby the concept of organism continues to function in different contexts--as a heuristic, an explanatory challenge, a model of order, of regulation, etc.--despite having frequently been pronounced irrelevant and reduced to molecules or genes. Yet this perpetuation is far removed from any 'metaphysics of organism', or organismic biology.

A positive concept of health - interviews with patients and practitioners in an integrative medicine clinic.

Using the phenomenography method, interviews with patients and practitioners were undertaken to explore their understanding of 'health that is more than the absence of disease'. The question was challenging and stimulating for all interviewees. A few were unable to conceptualise this positive definition of health, some perceived it as an optimum end-state, whereas others saw it as an ongoing process. Many positive attributes of health and its influencers were identified. The more advanced understandings of this concept were of a holistic, multidimensional, expansive state where the all dimensions of health are interdependent and positively reinforcing. The results affirmed that wellness is more than psychological wellbeing, 'happiness' and life satisfaction. Optimum physical and cognitive capacities along with spiritual, social and occupational wellness were equally as important. 'Energy and vitality' were sufficiently emphasised by patients and some practitioners to support the inclusion of the principles of vitalism in any discussion about health.
