Ample research demonstrates that parents’ experience-based mental representations of attachment—cognitive models of close relationships—relate to their children’s social-emotional development. However, no research to date has examined how parents’ attachment representations relate to another crucial domain of children’s development: brain development. The present study is the first to integrate the separate literatures on attachment and developmental social cognitive neuroscience to examine the link between mothers’ attachment representations and 3- to 8-year-old children’s brain structure. We hypothesized that mothers’ attachment representations would relate (...) to individual differences in children’s brain structures involved in stress regulation—specifically, amygdala and hippocampal volumes—in part via mothers’ responses to children’s distress. We assessed 52 mothers’ attachment representations and children’s brain structure. Mothers’ secure base script knowledge was significantly related to children’s smaller left amygdala volume but was unrelated to hippocampal volume; we found no indirect links via maternal responses to children’s distress. Exploratory analyses showed associations between mothers’ attachment representations and white matter and thalamus volumes. Together, these preliminary results suggest that mothers’ attachment representations may be linked to the development of children’s neural circuitry related to stress regulation. (shrink)

Those working within the tradition of Humean psychology tend to mark a clear distinction between beliefs and desires. One prominent way of elucidating this distinction is to describe them as having different “directions of fit” with respect to the world. After first giving a brief overview of the various attempts to carry out this strategy along with their flaws, I argue that the direction of fit metaphor is misleading and ought to be abandoned. It fails to take into account the (...) actual complexity of the roles played by belief and desire and forces us to look for a single, fundamental contrast between these two that is unlikely to be found.

Orthorexia is a condition in which the subject becomes obsessed with identifying and maintaining the ideal diet, rigidly avoiding foods perceived as unhealthy or harmful. In this paper, I examine widespread cultural factors that provide particularly fertile ground for the development of orthorexia, drawing out social and historical connections between religion and orthorexia (which literally means “righteous eating”), and also addressing how ambiguities in the concept of “health” make it particularly prone to take on quasi-religious significance. I argue that what (...) makes this sort of disordered eating destructive to both men and women is ultimately a common urge to transcend rather than to embrace the realities of embodiment. In sum, I believe that orthorexia is best understood as a manifestation of age-old anxieties about human nitude and mortality—anxieties which current dominant sociocultural forces prime us to experi- ence and express in unhealthy attitudes toward healthy eating.

Altruism is a central concept in evolutionary biology. Evolutionary biologists still disagree about its meaning (E.O. Wilson 2005; Fletcher et al. 2006; D.S. Wilson 2008; Foster et al. 2006a, b; West et al. 2007a, 2008). Semantic disagreement appears to be quite robust and not easily overcome by attempts at clarification, suggesting that substantive conceptual issues lurk in the background. Briefly, group selection theorists define altruism as any trait that makes altruists losers to selfish traits within groups, and makes groups of (...) altruists fitter than groups of non-altruists. Inclusive fitness theorists reject a definition based on within- and between-group fitness. Traits are altruistic only if they cause a direct and absolute fitness loss to the donor. The latter definition is more restrictive and rejects as cases of altruism behaviors that are accepted by the former. Fletcher and Doebeli (2009) recently proposed a simple, direct and individually based fitness approach, which they claim returns to first principles: carriers of the genotype of interest “must, on average, end up with more net direct fitness benefits than average population members.” This seductively simple proposal uses the concept of assortment to explain how diverse kinds of altruists end up on average with more net fitness than their non-altruistic rivals. In this paper I shall argue that their approach implies a new concept of altruism that contrasts with and improves on the concept of the inclusive fitness approach. (shrink)

This paper describes a computational model of how ideas, or memes, evolve through the processes of variation, selection, and replication. Every iteration, each neural-network based agent in an artificial society has the opportunity to acquire a new meme, either through 1) INNOVATION, by mutating a previously-learned meme, or 2) IMITATION, by copying a meme performed by a neighbor. Imitation, mental simulation, and using past experience to bias mutation all increase the rate at which fitter memes evolve. Memes at epistatic (...) loci converged more slowly than memes at over- or underdominant loci. The higher the ratio of innovation to imitation, the greater the meme diversity, and the higher the fitness of the fittest meme. Optimization is fastest for the society as a whole with an innovation to imitation ratio of 2:1, but diversity is comprimized. (shrink)

Exercise may influence components of executive functioning, specifically cognitive control and action monitoring. We aimed to determine whether high level exercise improves the efficacy of cognitive control in response to differing levels of conflict. Fitter individuals were expected to demonstrate enhanced action monitoring and optimal levels of cognitive control in response to changing task demands. Participants were divided into the highly active or low-active group based on self-reported activity using the International Physical Activity Questionnaire. A modified flanker task was (...) then performed, in which the level of conflict was modulated by distance of distractors from the target and congruency of arrows. Electroencephalography was collected during 800 trials; trials were 80% congruent, 20% incongruent, 50% close, and 50% far. The error-related negativity and error positivity were extracted from the difference wave of correct and incorrect response locked epochs, the N2 from the difference wave of congruent and incongruent stimulus locked epochs and the P3 from stimulus locked epochs. The HA group showed a larger Pe amplitude compared to the low-active group. Close trials elicited a larger N2 amplitude than far trials in the HA group, but not the low-active group, the HA group also made fewer errors on far trials than on close trials. Finally, the P3 was smaller in the lowest conflict condition in the HA, but not the low-active group. These findings suggest that habitual, high levels of exercise may influence the endogenous processing involved in pre-response conflict detection and the post-error response. (shrink)

Combining two central topics in philosophy in the 20th Century, this book considers the ethics and impact of decision-making alongside the philosophy of time. When we make simple decisions, like the decision to wake up at 8 a.m. tomorrow, we make use of a linear model of the future. But when we make open-ended decisions, like the decision to get fitter, or more involved in politics, we presuppose a much more complex model of the future. We project a variety (...) of virtual futures. We can carry out a decision in many different ways at once, which may converge and diverge at different points in time. Using a phenomenological approach, The Many Futures of a Decision explores what we learn about the structure of the future specifically from decision-making. Most theories of decision concentrate on the rationality: the evidence and value assessments that build up grounds for a rational decision. Instead, this book innovatively engages with the nature of the future as a multi-layered decisions project. Through interpretations of the theories of decision in philosophers like Husserl and Heidegger, Schmitt and Habermas, Derrida and Deleuze, along with other decision theories, Lampert develops an original theory of multiple futures."--Bloomsbury Publishing.

Evolutionary economics often focuses on the comparison between economic competition and the process of natural selection to select the fitter members of a given population. But that neglects the other "half" of an evolutionary process, the mechanism for the generation of new possibilities that is key to dynamic efficiency. My topic is the process of parallel experimentation which I take to be a process of multiple experiments running concurrently with some form of common goal, with some semi-isolation between the (...) experiments, with benchmarking comparisons made between the experiments, and with the "migration" of discoveries between experiments wherever possible to ratchet up the performance of the group. The thesis is that parallel experimentation is a fundamental dynamic efficiency scheme to enhance and accelerate variation, innovation, and learning in contexts of genuine uncertainty or known ignorance. Within evolutionary biology, this type of parallel experimentation scheme was developed in Sewall Wright's shifting balance theory of evolution. It addressed the rather neglected topic of how a population on a low fitness peak might eventually be able to go "downhill" against selective pressures, traverse a valley of low fitness, and then ascend a higher fitness peak. The theme of parallel experimentation is used to recast and pull together dynamic and pluralistic theories in economics, political theory, philosophy of science, and social learning. (shrink)

Is there some general reason to expect organisms that have beliefs to have false beliefs? And after you observe that an organism occasionally occupies a given neural state that you think encodes a perceptual belief, how do you evaluate hypotheses about the semantic content that that state has, where some of those hypotheses attribute beliefs that are sometimes false while others attribute beliefs that are always true? To address the first of these questions, we discuss evolution by natural selection and (...) show how organisms that are risk-prone in the beliefs they form can be fitter than organisms that are risk-free. To address the second question, we discuss a problem that is widely recognized in statistics – the problem of over-fitting – and one influential device for addressing that problem, the Akaike Information Criterion (AIC). We then use AIC to solve epistemological versions of the disjunction and distality problems, which are two key problems concerning what it is for a belief state to have one semantic content rather than another.

This paper tries to explain how individuals manage adaptive individual choice (i.e., the decision to acquire a fitter than average behavior or idea rapidly and tractably) in cultural evolution, despite the fact that acquiring fitness information is very difficult. I argue that the means of solving this problem suggested in the cultural evolution literature largely are various types of decision rules employing representations of fitness correlated properties or states of affairs. I argue that the problem of adaptive individual choice (...) is best solved where some of these learning rule representations are socially transmitted and some are biologically transmitted. (shrink)

The probability that the fitter of two alleles will increase in frequency in a population goes up as the product of N (the effective population size) and s (the selection coefficient) increases. Discovering the distribution of values for this product across different alleles in different populations is a very important biological task. However, biologists often use the product Ns to define a different concept; they say that drift “dominates” selection or that drift is “stronger than” selection when Ns is (...) much smaller than some threshold quantity (e.g., ½) and that the reverse is true when Ns is much larger than that threshold. We argue that the question of whether drift dominates selection for a single allele in a single population makes no sense. Selection and drift are causes of evolution, but there is no fact of the matter as to which cause is stronger in the evolution of any given allele. (shrink)

The phenomenon of eSports is omnipresent today. International championships and their competitive athletes thrill millions of spectators who watch eSports athletes and their teams try to improve and outperform each other. In order to achieve the necessary cognitive and physical top form and to counteract general health problems caused by several hours of training in front of the PC or console, eSports athletes need optimal cognitive, physical and mental training. However, a gap exists in eSports specific health management, including prevention (...) of health issues and training of these functions. To contribute to this topic, we present in this mini review possible avenues for holistic training approaches for cognitively, physically and mentally fitter and more powerful eSports athletes based on interdisciplinary findings. Furthermore, we discuss exergames as a motivating and promising complementary training approach for eSports athletes, which simultaneously combines physical and cognitive stimulation and challenges in an attractive gaming environment. Exergames have the high potential to penetrate new applications and thus influence the growing eSports research and development community. (shrink)

I argue that the idea of ‘quasi-independence’ [Lewontin, R. C. . Adaptation. Scientific American, 239, 212–230] cannot be understood without attending to the distinction between fitness and advantageousness [Sober, E. . Philosophy of biology. Boulder: Westview Press]. Natural selection increases the frequency of fitter traits, not necessarily of advantageous ones. A positive correlation between an advantageous trait and a disadvantageous one may prevent the advantageous trait from evolving. The quasi-independence criterion is aimed at specifying the conditions under which advantageous (...) traits will evolve by natural selection in this type of situation. Contrary to what others have argued [Sterelny, K. . Evolutionary explanations of human behavior. Australian Journal of Philosophy, 70, 156–172, and Sterelny, K., & Griffiths, P. . Sex and death. Chicago: University of Chicago Press], these conditions must involve a precise quantitative measure of the extent to which advantageous traits are beneficial, and the degree to which they are correlated with other traits. Driscoll [Driscoll, C. . Can behaviors be adaptations? Philosophy of Science, 71, 16–35] recognizes the need for such a measure, but I argue that she does not provide the correct formulation. The account of quasi-independence that I offer clarifies this point. (shrink)

As the rapidly advancing possibilities of biotechnology have outstripped the adaptive capacity of current legal and ethical institutions, a vigorous debate has arisen that considers the boundaries of appropriate use of this technology, particularly when applied to humans. This article examines ethical concerns surrounding the development of markets in a particular form of human genetic engineering in which heterozygotes are fitter than both homozygotes, a condition known as heterozygous advantage. To begin, we present a generalized model of the condition, (...) illuminated by the application to sickle-cell anemia. Next, we propose a typology of related markets, some of which are currently functioning with available products and services, and others that are widely viewed as imminent. We suggest the manner in which perverse incentives may arise for firms that market genetic intervention in circumstances where heterozygous advantage is possible. Finally, we propose that this misalignment of incentives with social welfare has arisen from both ill-conceived market intervention where markets are capable of achieving efficient outcomes and the lack of market intervention where markets have failed. We offer specific legal and regulatory approaches for reform. (shrink)

Susan Mills and John Beatty proposed a propensity interpretation of fitness (1979) to show that Darwinian explanations are not circular, but they did not address the critics' chief complaint that the principle of the survival of the fittest is either tautological or untestable. I show that the propensity interpretation cannot rescue the principle from the critics' charges. The critics, however, incorrectly assume that there is nothing more to Darwin's theory than the survival of the fittest. While Darwinians all scoff at (...) this assumption, they do not agree about what role, if any, this principle plays in Darwin's theory of natural selection. I argue that the principle has no place in Darwin's theory. His theory does include the idea that some organisms are fitter than others. But greater reproductive success is simply inferred from higher fitness. There is no reason to embody this inference in the form of a special principle of the survival of the fittest. (shrink)

Multilingual dictionary of philosophical terms.

Although coherence has become one of the key concepts in contemporary legal theory, its meaning is taken almost universally to be elusive, complex and controversial. However, these difficulties are due just to the failure of commentators to distinguish the intension of the notion from other features of its (many) referents in extension. The oversight has caused qualities to be ascribed routinely to coherence that properly attach to various object(s) of which coherence is predicated, and which a theorist happens to have (...) in mind when bringing coherence into view. This conceptual error has significance for the substance of present claims made for the use of the notion in law. Freed from the entanglement, coherence emerges thinner and fitter, better able to be deployed with confidence in legal application. (shrink)

I agree with George Williams's most significant point: both questions and answers about our moral natures lie in our biological origins. He fails, however, to show that nature is morally evil and that therefore we should vigilantly resist it. The products of evolution are morally neutral, but the human moral sense is arguably a positive good. Morality is functional. It does not require ultimate justification in the sense of correspondence with or attack upon reality “out there.” It is an adaptation (...) “intended” to make us social, and sociality—with its sense of right and wrong—makes us fitter than otherwise.

Using relevant encyclicals issued over the last 100 years, the author extracts those principles that constitute the underpinnings of Catholic Social Teaching about the employment relationship and contemplates implications of their incorporation into human resource policy. Respect for worker dignity, for his or her family's economic security, and for the common good of society clearly emerge as the primary guidelines for responsible human resource management. Dovetailing these three Church mandates with the economic objectives of the firm could, in essence, alter (...) the firm's nature because profit motivations would be constrained by consideration for worker and societal welfare. Integration of Church teaching with current corporate goals should therefore impact greatly on a variety of human resource policies. (shrink)
