What are the processes, from conception to adulthood, that enable a single cell to grow into a sentient adult? Neuroconstructivism is a pioneering 2 volume work that sets out a whole new framework for considering the complex topic of development, integrating data from cognitive studies, computational work, and neuroimaging.

What makes us conscious? Many theories that attempt to answer this question have appeared recently in the context of widespread interest about consciousness in the cognitive neurosciences. Most of these proposals are formulated in terms of the information processing conducted by the brain. In this overview, we survey and contrast these models. We first delineate several notions of consciousness, addressing what it is that the various models are attempting to explain. Next, we describe a conceptual landscape that addresses how the (...) theories attempt to explain consciousness. We then situate each of several representative models in this landscape and indicate which aspect of consciousness they try to explain. We conclude that the search for the neural correlates of consciousness should be usefully complemented by a search for the computational correlates of consciousness. (shrink)

It is often assumed that similar domain-specific behavioural impairments found in cases of adult brain damage and developmental disorders correspond to similar underlying causes, and can serve as convergent evidence for the modular structure of the normal adult cognitive system. We argue that this correspondence is contingent on an unsupported assumption that atypical development can produce selective deficits while the rest of the system develops normally (Residual Normality), and that this assumption tends to bias data collection in the field. Based (...) on a review of connectionist models of acquired and developmental disorders in the domains of reading and past tense, as well as on new simulations, we explore the computational viability of Residual Normality and the potential role of development in producing behavioural deficits. Simulations demonstrate that damage to a developmental model can produce very different effects depending on whether it occurs prior to or following the training process. Because developmental disorders typically involve damage prior to learning, we conclude that the developmental process is a key component of the explanation of endstate impairments in such disorders. Further simulations demonstrate that in simple connectionist learning systems, the assumption of Residual Normality is undermined by processes of compensation or alteration elsewhere in the system. We outline the precise computational conditions required for Residual Normality to hold in development, and suggest that in many cases it is an unlikely hypothesis. We conclude that in developmental disorders, inferences from behavioural deficits to underlying structure crucially depend on developmental conditions, and that the process of ontogenetic development cannot be ignored in constructing models of developmental disorders. Key Words: Acquired and developmental disorders; connectionist models; modularity; past tense; reading. (shrink)

Neuroconstructivism: How the Brain Constructs Cognition proposes a unifying framework for the study of cognitive development that brings together (1) constructivism (which views development as the progressive elaboration of increasingly complex structures), (2) cognitive neuroscience (which aims to understand the neural mechanisms underlying behavior), and (3) computational modeling (which proposes formal and explicit specifications of information processing). The guiding principle of our approach is context dependence, within and (in contrast to Marr [1982]) between levels of organization. We propose that three (...) mechanisms guide the emergence of representations: competition, cooperation, and chronotopy; which themselves allow for two central processes: proactivity and progressive specialization. We suggest that the main outcome of development is partial representations, distributed across distinct functional circuits. This framework is derived by examining development at the level of single neurons, brain systems, and whole organisms. We use the terms encellment, embrainment, and embodiment to describe the higher-level contextual influences that act at each of these levels of organization. To illustrate these mechanisms in operation we provide case studies in early visual perception, infant habituation, phonological development, and object representations in infancy. Three further case studies are concerned with interactions between levels of explanation: social development, atypical development and within that, developmental dyslexia. We conclude that cognitive development arises from a dynamic, contextual change in embodied neural structures leading to partial representations across multiple brain regions and timescales, in response to proactively specified physical and social environment.

Contributing to the cultural ecosystem services literature, this paper draws on the in-depth place narratives of two coastal case-study sites in Wales (UK) to explore how people experience and understand landscape change in relation to their sense of place, and what this means for their wellbeing. Our place narratives reveal that participants understand coastal/intertidal landscapes as complex socio-ecological systems filled with competing legitimate claims that are difficult to manage. Such insights suggest that a focus on diachronic integrity (Holland and O'Neill (...) 1996) within place narratives might offer a route to more socially and culturally acceptable environmental management strategies.

We develop an axiomatic theory of “generalized Routley-Meyer logics.” These are first-order logics which are can be characterized by model theories in a certain generalization of Routley-Meyer semantics. We show that all GRM logics are subclassical, have recursively enumerable consequence relations, satisfy the compactness theorem, and satisfy the standard structural rules and conjunction and disjunction introduction/elimination rules. We also show that the GRM logics include classical logic, intuitionistic logic, LP/K3/FDE, and the relevant logics.

The notion of Hegel's Dialectic has been largely critiqued and thoroughly regarded as largely a headache in the realm of metaphysics. In this work, I made the attempt to navigate and substantiate the complexity of an adapted reiteration of those fundamental Dialectical notions in conjunction with a more focused description of Idealism that attempts to substantiate itself within the bounds of our current understanding of physics and QM. This papers goal is to serve more than anything as an entry point (...) for a discussion of metaphysical prospects in the vein of Hegelian Phenomenology and ways in which we can restructure such notions into a theory compatible with current understandings of material reality such that we may be able to make meaningful progress to unraveling more of the mysteries on the composition and unfolding of our reality.

Hydraulic fracturing (‘fracking') has enabled the recovery of previously inaccessible resources and rendered new areas of the underground ‘productive’. While a number of studies in the US and UK have examined public attitudes toward fracking and its various impacts, how people conceptualise the deep underground itself has received less attention. We argue that views on resources, risk and the deep underground raise important questions about how people perceive the desirability and viability of subterranean interventions. We conducted day-long deliberation workshops (two (...) in each country), facilitating discussions among diverse groups of people on prospective shale extraction in the US and UK. Themes that emerged in these conversations include seeing the Earth as a foundation; natural limits (a greater burden than the subsurface can withstand versus simply overuse of natural resources); and ideas about the fragility, instability and opacity of the deep underground. We find that concerns in both countries were not limited to specific, localised impacts but also addressed ecosystem links between surface and subsurface environments and broader questions about the use, identification and value of natural resources.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

The issue of detention as a tuberculosis control measure has resurfaced following the prolonged detention of a patient with an extensively drug-resistant strain of tuberculosis in a prison cell in Arizona, and the attempted detention in Italy and subsequent detention in Atlanta, Georgia of an American sufferer thought to have XDR-TB in May 2007. These cases have reignited the debate over the evidence that supports detention policy in the control of tuberculosis, and its associated legal and ethical ramifications. This paper (...) considers whether involuntary detention is justified where voluntary measures have failed or where a patient poses a danger, albeit uncertain, to the public, and discusses the need for strengthening evidencebased assessments of public health risk.

Leadership takes a central role in the public affairs agenda. This article is a review of published works on leadership focusing on the concept of grace. It discusses the role of compassion and kindness in current leadership theory and practice and whether these attributes have value in sustainable models. Findings indicate that there is conceptual confusion regarding the definition of compassion and its application in leadership practices. Kindness is not discussed within the concept of compassion and kindness itself may be (...) viewed as a weakness in contemporary self-selected leadership characteristics. The conclusions suggest there is disconnect between contemporary models of leadership and calls for sustainable ethical leadership in the spheres of public and business environments. Compassion and kindness remain in the side-lines yet the implications for future trust and commitment are neglected in times where discretionary effort of workers and volunteers is crucial to goal achievement.

Robert Merrihew Adams argues that it is permissible for a perfectly good moral agent to create a world less good than the best one she could create. He argues that God would exhibit the important virtue of grace in creating less than the best and that this virtue is incompatible with the merit considerations required by the standard of creating the best. In this paper I give three arguments for the compatibility of merit consideration and graciousness of God toward creation. (...) I conclude that grace would not release a perfect agent from responsibility to create the best. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:149. RELATIVE IDEAS REJECTED Hume's claim that ideas copy impressions seems to provide prima facie evidence for the interpretation that he also believed that all thought is restricted to images. Clearly such a view would be fatal to Hume's epistemological framework for at least two reasons. The first reason is quite simply that images are not a necessary element for thought, since we rarely think in images or pictures. (...) The second reason is that the imagistic interpretation prevents the possibility of universal a priori knowledge; since images only represent particulars they can never permit the inference from knowledge of particular instances to knowledge of universal cases. Yolton's paper, "Hume's Ideas", is a valiant effort to save Hume from the crippling imagistic interpretation. Although Yolton presents a reading of the Treatise that might avoid this interpretation, he fails to provide a sufficiently detailed account of any one counter-example to the imagistic view of Hume. However, such a counter-example has been worked out in Flage's 2 recent paper "Hume's Relative Ideas". Although the search for non-picturable ideas in Hume's system, and subsequent destruction of the imagistic interpretation is an admirable path for investigation, I intend to show that Flage's attempt to produce a Humean theory of non3 picturable "relative" ideas is entirely misguided. I shall argue that Flage has produced a theory without application in Hume's framework, a theory actually based on a distinction between relative ideas and relations of ideas, that Hume never intends. Flage argues that Hume has a theory of relative ideas, and that the application of this theory can produce intelligible concepts of essentially imperceptible 150. objects. A relative idea is obtained by an inference, of sorts, from the relations of ideas obtained from impressions; or in Flage' s words, a relative idea "singles out an unperceived entity on the basis of its relations to a perceived entity, i.e. a positive [picturable] idea" (HS 56). Flage admits that "Hume often regarded epistemic claims based upon relative ideas with at least a modicum of scepticism" (HS 55). He also realizes that no such theory of relative ideas can be used to justify ontological claims of the unperceivable objects (HS 63), but that "the doctrine of relative ideas at least accounts for the intelligibility of various concepts" (HS 59). Flage applies the theory of relative ideas to three concepts that Hume discusses in an effort to demonstrate how this theory can make these concepts intelligible. The three concepts are substratum, the missing shade of blue, and the idea of a thousandth part of a grain of sand; however, Flage fails to realize that Hume successfully argues against the intelligibility of these concepts. I shall present the arguments that Hume gives to show that Flage' s theory of relative ideas does not apply in the cases he argues for. Hopefully this will show that Flage has created a theory that lacks application; however, this is not Flage' s only failing. "Relative" ideas are obtained from relations of ideas (HS 56), and by this description Flage has implicitly distinguished between Hume's use of "relative" and the philosophical "relations of ideas!', a distinction that Hume never intends. In the latter part of this paper I shall show that Hume uses "relative" to refer to the relations of ideas, and that Flage has simply located and produced a theory on the basis of a distinction that has no real difference. In the discussion of substance, Flage correctly points out that Hume distinguishes three definitions of substance in the fourth part of book I of the Treatise (HS 63-4). 151. Flage also correctly points out that at least two of these definitions are unintelligible (HS 64). The definition of substance, as an autonomous object that is distinct from dependent qualities, fails to properly 4 distinguish substance from qualities (T 233), and substance defined as the "subject of inhesion" fails because there is no empirical evidence to justify the claim that qualities inhere in a substance J(T 234). However, Flage incorrectly argues that Hume asserts that the idea of substance as "the entity that is simple and identical through time... (shrink)

I am the LawIt is hard to imagine two more disparate characters than Judge Joseph Dredd and Hercules J—the one an over-muscular, faceless and heavily armed street judge astride a Lawmaster motorcycle who overidentifies with his role ; the other devoid of any physical presence or image, and structurally decoupled from the execution of law by a fierce determination to maintain the separation of powers and accountability which Dredd so effortlessly ignores. Hercules J is the embodiment of an intellectualised, yet (...) creative, operationalisation of law. To the academic spirit, Hercules is infinitely preferable as a model of judicial activism: his world conjures a contemplative modality, ever alert to the requirements of rights and largely aligned with the temper of the post-Enlightenment. By contrast, Dredd is the personification of the worst aspects of law-and-order as the debased and politicised manifestation of the Rule of Law. His is an intensely visceral presence, the metonymic blindness of Themis replaced by the Dredd’s fractured eyeline: blindness as a signifier of impartiality yields to blindness as a symptom of institutional rage. This article interrogates the characters, actions and values of Hercules J and Dredd J, viewed primarily through the lens of Jacques Derrida’s Force of Law, focusing on the relationship between law and violence as it is exposed in Hercules’s and Dredd’s worlds, and then turning to judicial confrontation with the aporetic: the aporias, identified by Derrida and others, that law must confront. The interrogation continues, finally contemplating the current state of law in the common law world—the world of liberal democracies, suggesting that the high point of democracy may well have passed, and that we are on a Dredd-ward trajectory.

The Oxford Handbook of Comparative Political Theory provides an entry point into this burgeoning field by both synthesizing and challenging the terms that motivate it. The handbook demonstrates how mainstream political theory can and must be enriched through attention to genuinely global, rather than parochially Euro-American, contributions to political thinking. Entries emphasize exploration of substantive questions about political life-ranging from domination to political economy to the politics of knowledge-in a range of global contexts, with attention to whether and how those (...) questions may be shared, contested, or reformulated across differences of time, space, and experience. They connect comparative political theory to cognate disciplines including postcolonial theory, area studies, and comparative politics. Creative organizational tools such as tags and keywords aid in navigation of the handbook to help readers trace disruptions, thematic connections, contrasts, and geographic affinities across entries.

The success of the early music movement has long raised questions about performing historical works: Should musicians perform on period instruments and try to reconstruct the original style? If a historically “authentic” performance is impossible or undesirable, what should be the goal of the early music movement? I turn to Gadamer to answer these questions by constructing the outlines of a hermeneutics of early music performance. In the first half of the paper, I examine Gadamer’s critique of historical reconstruction and (...) argue that this critique sheds light on mistaken tendencies and misunderstandings within the early music movement, but it does not discredit the movement as such. In the second half of the paper, I attempt to show how Gadamer’s dialogical account of historical consciousness provides a framework for understanding what historically informed performance is seeking to accomplish, as well as its advantage over a Nietzschean approach.

Review article on Philipp Höfele's book "Wollen und Lassen: Zur Ausdifferenzierung, Kritik und Rezeption des Willensparadigmas in der Philosophie Schellings" (Freiburg: Alber, 2019). The book demonstrates why Schelling is not an uncritical predecessor of Nietzsche and the will to power, as Heidegger alleges. Instead, Schelling displays an ambivalent attitude toward willing—affirming it in some forms, critiquing or rejecting it in others. Above all, Schelling’s thought on the will has many layers of complexity: it includes not only a variety of forms (...) of willing, but also “fringe phenomena” like non-willing or Gelassenheit that are ordinarily placed in opposition to will. Moreover, Schelling’s philosophy of will is distinctive in not conceiving willing and letting-be as either-or alternatives, as Heidegger tends to do. Especially in the late lectures, Schelling brings them together, showing how non-voluntary phenomena like Gelassenheit make an authentic willing possible. (shrink)

In this paper I will explore Samuel Beckett’s significant, yet overlooked, contribution to the study of asceticism and ascetic thought. I will present a reading of Beckett’s seminal play, Waiting for Godot, so as to illustrate the way in which Beckett utilizes and develops numerous aspects of Arthur Schopenhauer’s philosophical system. As I understand it, the Beckettian asceticism manifested in the tragedies of Beckett’s middle period not only utilizes aspects of Schopenhauerian asceticism, it also incorporates broader, non-ascetic aspects of Schopenhauerian (...) thought – namely that of boredom, and the aesthetic theory of the dynamically sublime. In contrast to Schopenhauerian asceticism, which focuses on bodily deprivation, Beckettian asceticism impoverishes not only the body but also the mind. Through the medium of tragedy, Beckett presents a unique ascetic method that centres on impoverishing the mind by preventing the formation of useful, or actionable, representations. (shrink)

In this essay, I give an analysis of the account of non-being in the Weltalter, focusing on the ways in which this account reflects Schelling’s new ontology of revelation. I begin by discussing the connection between non-being and the fundamental distinction between the principles in God. I then turn to the relationship of non-being to being in the Weltalter and show how a new meaning of being allows Schelling to distinguish non-being from nothing. The new meaning of being also makes (...) possible a distinction between essential non-being and de facto non-being; this distinction allows for the temporal sequence of revelation and the possibility of evil. I conclude by showing the implications of Schelling’s theory of non-being for his understanding of creation. (shrink)

In the Freedom Essay, Schelling provides four different accounts of the copula, two of which are largely implicit. In this paper, I focus on the first of these accounts, which I call the "mediated account." I argue that this explanation of the copula articulates a fundamental ontological structure in Schelling's philosophy. In the first half of the paper, I analyze the structural features of the account, drawing on Schelling's more extensive treatment in the Ages of the World. In the second (...) half of the paper, I argue that Schelling's fundamental distinction between that-which-exists and the ground of existence exhibits the same structure as the mediated account of the copula. This has implications for understanding the enigmatic relationship of these two principles to the Ungrund. I conclude by briefly suggesting other applications of this fundamental structure in Schelling's philosophy. (shrink)

At first glance, Schopenhauer’s account of human freedom looks strikingly similar to Schelling’s account of formal freedom in the Freiheitsschrift. Despite the clear similarities, I argue that there is a decisive difference between the two accounts—a difference that has to do with the ultimate grounding of freedom. For Schelling, the intelligible deed is a radical self-grounding of the eternal essence of the human being. For Schopenhauer, the eternal essence of the human being is groundless. Moreover, I argue that this difference (...) has decisive consequences for two sets of issues. On the one hand, Schelling’s concept of self-grounding allows him to preserve the universal application of the principle of ground. On the other hand, self-grounding is the only way that human beings can be responsible for who they are. Schelling thus anticipates a key insight of Galen Strawson: ultimate moral responsibility is only possible for a causa sui. (shrink)

In this paper I investigate the relationship between the serious and the playful elements in Socrates’ character as these unfold within the context of Xenophon’s Symposium. For the Greeks, the concept of value is attached to the meaning of seriousness, and this accounts for the natural preference for the serious over the playful. Despite the potential rivalry of the playful and philosophy, Socrates mixes the playful with the serious in such a way as to conceal their boundary. This mixing serves (...) the purpose of education, by both attracting us to Socrates and placing us at a distance from the intended meaning of his words. (shrink)

Historians of science have only just begun to sample the wealth of different approaches to the study of animal behavior undertaken in the twentieth century. To date, more attention has been given to Lorenzian ethology and American behaviorism than to other work and traditions, but different approaches are equally worthy of the historian's attention, reflecting not only the broader range of questions that could be asked about animal behavior and the "animal mind" but also the different contexts in which these (...) questions were important. One such approach is that represented by the work of the French zoologist Louis Boutan (1859-1934). This paper explores the intellectual and cultural history of Boutan's work on animal language and the animal mind, and contextualizes the place of animal behavior studies within late-nineteenth- and early-twentieth-century French biology. I explore the ways in which Boutan addressed the philosophical issue of whether language was necessary for abstract thought and show how he shifted from the idea that animals were endowed with a purely affective language to the notion that of they were capable of "rudimentary" reasoning. I argue that the scientific and broader socio-cultural contexts in which Boutan operated played a role in this transition. Then I show how Boutan's linguistic and psychological experiments with a gibbon and children provide insights into his conception of "naturalness." Although Boutan reared his gibbon at home and studied it in the controlled environment of his laboratory, he continued to identify its behavior as "natural." I specifically demonstrate the importance of the milieu of the French Third Republic in shaping Boutan's understanding not only of animal intelligence and child education, but also his definition of nature. Finally, I argue that Boutan's studies on the primate mind provide us with a lens through which we can examine the co-invention of animal and child psychology in early-twentieth-century France.

We use a result due to Rolin, Speissegger, and Wilkie to show that definable sets in certain o-minimal structures admit definable parameterizations by mild maps.

In fact, Trotsky’s thinking continued to develop in response to new developments after 1936.

What is successful Christian leadership? How should leadership be developed within a Christian context? This article encourages Christian leaders to seek to identify with Jesus’ mission and paradigm in developing leaders by examining the Scriptural passage in Mark 3:13-19. Jesus’ example in leadership development was based on succession of leadership primarily accomplished through personally shaping his disciples in close, mentoring relationships. This article, in particularly examines Jesus’ practice of having his disciples near him in order that they might best accomplish (...) the task he had purposed for them. Currently, this pattern of leadership development has been given diverse definitions from servant-based leadership to transformational leadership, but to Jesus, developing leaders was best accomplished through simple mentoring. Jesus’ desired goals for his disciples were realized through an intentional nearness to the lives of the twelve. For Christian leadership to be healthy, its success depends on close relationships being developed between the mentor and the mentee. The indispensable mark of Christian leadership is the combined effort of action and agenda while purposing to influence others. (shrink)

Review article on Alexander Schnell’s book “Hinaus: Entwürfe zu einer phänomenologischen Metaphysik und Anthropologie” (Würzburg: Königshausen & Neumann, 2011). According to Schnell, an exclusively descriptive phenomenology is not enough; phenomenology must also be constructive. He thus outlines an ambitious project for constructive phenomenology that promises (1) to provide an ultimate justification for knowledge and (2) to ground a phenomenological metaphysics and anthropology, each of which is centered on the “image” (Bild). Insofar as Schnell fills in the details of this outline, (...) his analysis is careful, provocative, and filled with insight. (shrink)

What are the processes, from conception to adulthood, that enable a single cell to grow into a sentient adult? The processes that occur along the way are so complex that any attempt to understand development necessitates a multi-disciplinary approach, integrating data from cognitive studies, computational work, and neuroimaging - an approach till now seldom taken in the study of child development. Neuroconstructivism is a major new 2 volume publication that seeks to redress this balance, presenting an integrative new framework for (...) considering development. In the first volume, the authors review up-to-to date findings from neurobiology, brain imaging, child development, computer and robotic modelling to consider why children's thinking develops the way it does. They propose a new synthesis of development that is based on 5 key principles found to operate at many levels of descriptions. They use these principles to explain what causes a number of key developmental phenomena, including infants' interacting with objects, early social cognitive interactions, and the causes of dyslexia. The "neuroconstructivist" framework also shows how developmental disorders do not arise from selective damage to the normal cognitive system, but instead arise from developmental processes that operate under atypical constraints. How these principles work is illustrated in several case studies ranging from perceptual to social and reading development. Finally, the authors use neuroimaging, behavioural analyses, computational simulations and robotic models to provide a way of understanding the mechanisms and processes that cause development to occur.

In this paper we describe some first steps for bringing the framework of branching space-times (BST) to bear on quantum information theory. Our main application is quantum error correction. It is shown that BST offers a new perspective on quantum error correction: as a supplement to the orthodox slogan, “fight entanglement with entanglement”, we offer the new slogan, “fight indeterminism with indeterminism”.

In the multidisciplinary field of developmental cognitive neuroscience, statistical associations between levels of description play an increasingly important role. One example of such associations is the observation of correlations between relatively common gene variants and individual differences in behavior. It is perhaps surprising that such associations can be detected despite the remoteness of these levels of description, and the fact that behavior is the outcome of an extended developmental process involving interaction of the whole organism with a variable environment. Given (...) that they have been detected, how do such associations inform cognitive-level theories? To investigate this question, we employed a multiscale computational model of development, using a sample domain drawn from the field of language acquisition. The model comprised an artificial neural network model of past-tense acquisition trained using the backpropagation learning algorithm, extended to incorporate population modeling and genetic algorithms. It included five levels of description—four internal: genetic, network, neurocomputation, behavior; and one external: environment. Since the mechanistic assumptions of the model were known and its operation was relatively transparent, we could evaluate whether cross-level associations gave an accurate picture of causal processes. We established that associations could be detected between artificial genes and behavioral variation, even under polygenic assumptions of a many-to-one relationship between genes and neurocomputational parameters, and when an experience-dependent developmental process interceded between the action of genes and the emergence of behavior. We evaluated these associations with respect to their specificity, to their developmental stability, and to their replicability, as well as considering issues of missing heritability and gene–environment interactions. We argue that gene–behavior associations can inform cognitive theory with respect to effect size, specificity, and timing. The model demonstrates a means by which researchers can undertake multiscale modeling with respect to cognition and develop highly specific and complex hypotheses across multiple levels of description.

Robert Yerkes is a pivotal figure in American psychology and primatology in the first half of the twentieth century. As is well known, Yerkes first studied ape intelligence in 1915, on a visit to the private California laboratory of the psychiatrist Gilbert Hamilton, a former student. Less widely appreciated is how far the work done at the Hamilton lab, in its aims and ambitions as well as its techniques, served as a template for much of Yerkes’s research thereafter. This paper (...) uses the Hamilton–Yerkes relationship to re-examine Yerkes’s career and, more generally, that of American psychology in the early twentieth century. Three points especially are emphasized: first, the role of Freudian psychoanalysis as a spur to Hamilton’s experimental studies of ape intelligence; second, the importance of Hamilton’s laboratory, with its semi-wild population of monkeys and ape, as a model for Yerkes’s efforts to create a laboratory of his own; and third, the influence on Yerkes of Hamilton’s optimism about experimental psychological studies of nonhuman primates as a source of lessons beneficial to a troubled human world.

Differences in socioeconomic status (SES) correlate both with differences in cognitive development and in brain structure. Associations between SES and brain measures such as cortical surface area and cortical thickness mediate differences in cognitive skills such as executive function and language. However, causal accounts that link SES, brain, and behavior are challenging because SES is a multidimensional construct: correlated environmental factors, such as family income and parental education, are only distal markers for proximal causal pathways. Moreover, the causal accounts themselves (...) must span multiple levels of description, employ a developmental perspective, and integrate genetic effects on individual differences. Nevertheless, causal accounts have the potential to inform policy and guide interventions to reduce gaps in developmental outcomes. In this article, we review the range of empirical data to be integrated in causal accounts of developmental effects on the brain and cognition associated with variation in SES. We take the specific example of language development and evaluate the potential of a multiscale computational model of development, based on an artificial neural network, to support the construction of causal accounts. We show how, with bridging assumptions that link properties of network structure to magnetic resonance imaging (MRI) measures of brain structure, different sets of empirical data on SES effects can be connected. We use the model to contrast two possible causal pathways for environmental influences that are associated with SES: differences in prenatal brain development and differences in postnatal cognitive stimulation. We then use the model to explore the implications of each pathway for the potential to intervene to reduce gaps in developmental outcomes. The model points to the cumulative effects of social disadvantage on multiple pathways as the source of the poorest response to interventions. Overall, we highlight the importance of implemented models to test competing accounts of environmental influences on individual differences. (shrink)

Paramedics encounter ethical dilemmas at work, and while previous research has improved ethics education and practice, more can be learned from the lived experience of paramedics facing ethical challenges. This paper explores the lived experience of two paramedics, one with five years’ experience, the other twenty, presented with comparable cases. The participants, who were interviewed in a broader qualitative study exploring practical wisdom, were asked to select a case involving ethical decision-making from their own practice experience. Semi-structured interviews employed the (...) five-step Critical Decision Method as a framework to explore various aspects of the decision-making process. The two cases were identified as exemplars of prominent themes suitable for discussion. The findings highlighted several factors that influence paramedic ethical decision-making, including practical wisdom, communication and teamwork, clinical support, and education. This case comparison identifies a greater need to focus education on the fostering of practical wisdom, and the development of non-technical skills such as communication and teamwork, supported by interprofessional education endeavours. Furthermore, greater access to support for paramedics must be available to further evolve practical wisdom. The combination of improved education and support will likely cater for the full spectrum of ethical challenges faced by paramedics in their work. (shrink)

We address two points in this commentary. First, we question the extent to which O'Brien & Opie have established that the classical approach is unable to support a viable vehicle theory of consciousness. Second, assuming that connectionism does have the resources to support a vehicle theory, we explore how the activity of the units of a PDP network might sum together to form phenomenal experience (PE).
