Data from 949 families of Caucasian and 400 families of Japanese ancestry who took part in the Hawaii Family Study of Cognition were used to ascertain the associations of parental cognitive ability, parental education and paternal occupation with offspring cognitive ability. In particular, analyses were focused on testing the possible moderating effects of parental socioeconomic status on the familial transmission of cognitive abilities. Parental cognitive ability was substantially associated and parental education and paternal occupation only trivially associated with offspring performance. (...) In contrast to the findings of Turkheimer etal. (2003), there was no evidence in these data that familiality for cognitive abilities was lower in the lower as opposed to upper levels of socioeconomic status. These results were consistent across measures, ethnicity and sex of offspring. (shrink)

This paper combines the social psychology concept of moral elevation with the evolutionary concept of traditions as descendant-leaving strategies to produce a new explanation of the role of saints in Christianity. Moral elevation refers to the ability of prosocial acts to inspire people to engage in their own acts of charity and kindness. When morally elevating stories and visual depictions become traditional by being passed from one generation to the next, they can produce prosocial behavior advantageous to survival and reproduction (...) among many generations of descendants. Traditions that increase the number of descendants in future generations can be seen as descendant-leaving strategies. Stories and visual depictions of the sacrifices of saints appear to be designed to produce states of moral elevation, and they have been transmitted from one generation to the next for many centuries. We propose that this ability of sacrificing saints to inspire future generations to engage in prosocial acts has contributed to the continuation and spread of Christianity. (shrink)

The branch of evolutionary theory known as signaling theory attempts to explain various forms of communication. Social scientists have explained many traditional rituals as forms of communication that promote cooperative social relationships among participants. Both evolutionists and social scientists have realized the importance of trust for the formation and maintenance of cooperative social relationships. These factors have led to attempts to apply signaling theory to traditional cultural rituals in various ways. This paper uses the traditional ritual of mumming in small (...) Newfoundland fishing villages to evaluate alternative hypotheses about the connection between rituals, communication, trust, and cooperation. Mumming is found to be most consistent with the hypothesis that it is a ritual of trust wherein participants take a specific type of risk: the risk of harm at the hands of other participants. Individuals who take this risk actively signal their trust. Conversely, individuals who restrain themselves from inflicting harm on other participants actively signal their trustworthiness. (shrink)

Humans appear to be possible candidates for group selection because they are often said to live in bands, clans, and tribes. These terms, however, are only names for conceptual categories of people. They do not designate enduring bounded gatherings of people that might be “vehicles of selection.” Hence, group selection has probably not been a major force in human evolution.

Many anthropological explanations of magical practices are based on the assumption that the immediate cause of performing an act of magic is the belief that the magic will work as claimed. Such explanations typically attempt to show why people come to believe that magical acts work as claimed when such acts do not identifiably have such effects. We suggest an alternative approach to the explanation of magic that views magic as a form of religious behavior, a form of communication that (...) promotes or protects cooperative social relationships. We suggest that all forms of religious behavior involve persons communicating acceptance of a supernatural claim and that this act communicates a willingness to accept nonskeptically the influence of the person making such a claim. Thus, religious behavior communicates a willingness to cooperate with the claim maker and others who accept his or her influence. We suggest that magic, which can be distinguished by the communicated acceptance of the claim that certain techniques have supernatural effects, also promotes cooperation. Different types of magic, including sorcery, love magic, and curing magic, can be shown to communicate different types of messages, such as a threat to use violence to punish unsocial behavior, sexual desire, or concern for a person's well-being. Ethnographic examples are used to support this hypothesis. This approach requires no assumptions about whether the practitioners of magic do or do not believe that the magical acts work as claimed. It attempts only to account for the identifiable talk and behavior that constitute magical acts by examining the identifiable, and often important, effects of these acts on the behavior of others.

Totemism, a topic that fascinated and then was summarily dismissed by anthropologists, has been resurrected by evolutionary psychologists' recent attempts to explain religion. New approaches to religion are all based on the assumption that religious behavior is the result of evolved psychological mechanisms. We focus on two aspects of Totemism that may present challenges to this view. First, if religious behavior is simply the result of evolved psychological mechanisms, would it not spring forth anew each generation from an individual's psychological (...) mechanisms? Yet, Australian Totemism, like other forms of Totemism, is profoundly traditional, copied by one generation from the prior ones for hundreds of generations. Regardless of personal inclinations, individuals are obligated to participate. Second, it is problematic to assume that all practitioners of Totemism actually believe their religious claims. We propose an alternative explanation that accounts for the persistence of Totemism and that does not rely on an assumption that its practitioners are preliterate or naive because they have strange beliefs. We focus on Totemism as a cultural mechanism aimed at building and sustaining social relationships among close and distant kinsmen. (shrink)

Andrews et al. present a clear discussion of the various criteria needed to identify adaptations. However, they also imply a history of the debate between adaptationists and their critics that is incomplete. The history implied is one of only genuine scientific disagreement. This neglects the role of nonscientific motives and strawman arguments on behalf of the critics of adaptationists.

The growing interest in dual‐inheritance models of human evolution has focused attention on culture as a means by which ancestors transmitted acquired phenotypic characteristics to their descendants. The ability of cultural behaviors to be repeatedly transmitted from ancestors to descendants enables individuals to influence their descendant‐leaving success over many more generations than are usually coclusive fitness. This essay proposes that traditional stories, or myths, can be seen as a way in which ancestors influence their descendant‐leaving success by influencing the behavior (...) of many generations of their descendants. The myth of Oedipus is used as an example of a traditional story aimed at promoting proper behavior and cooperation among kin. This interpretation of the Oedipus myth is contrasted with Freudian and structuralist interpretations. (shrink)

We are not convinced by Gangestad & Simpson that differential mating strategies within each sex would be greater than such strategies between sexes. The target article does not provide actual evidence of human males who do not desire mating with multiple females, or evidence that the benefits for females of short-term matings with multiple males have ever outweighed the associated costs.

This essay explores the dialectics of theory and practice in terms of argumentation theory. Adapting Jonsen and Toulmin's (1988) notion of a Theory-Practice spectrum, it conceives Theory and Practice as extreme ends of a continuum and discourses as falling at various points along the continuum. Every theoritical discourse has essential practical aspects, and every practical discourse has essential theoretical aspects. Practices are theorized to varying degrees but every practice is thorized to some degree. Reflective discourse, which is discourse about practice, (...) moves to and fro along the Theory-Practice continuum. Reflective discourse involves argumentation. Practical argumentation connects theory to practice; it appeals to general warrants, which may be simple or may tap into elaborate conceptual structures, in order to establish grounds for practical judgments. A practical discipline is a relatively coherent intellectual-professional enterprise that cultivates a field of social practice by engaging within itself and with practitioners in a reflective discourse. The argumentation of a practical discipline, like ordinary practical reflection, moves to and fro along the Theory-Practice continuum but in more methodical steps informed by systematic methodological reflection on the reflective process itself.

For a variety of reasons, including the common use of deception in psychology experiments, participants often disbelieve experimenters' assertions about important task parameters. This can lead researchers to conclude incorrectly that participants are behaving non- normatively. The problem can be overcome by deriving and testing normative models that do not assume full belief in key task parameters. A real experimental example is discussed.

Examining discourse markers (Schiffrin, 1987) in two transcribed discussions of controversial issues in an undergraduate 'critical thinking' class, we note frequent uses of 'I'm just saying' and related metadiscursive expressions (I'm/we're saying, I'm/we're not saying, etc.). Our central claim is that these 'saying' expressions are pragmatic devices by which speakers claim 'all along' to have held a consistent argumentative standpoint, one that continues through the discussion unless changed for good reasons. Through close analysis of a series of discourse examples, we (...) show how these discourse markers are used to display continuity, deflect counterarguments, and acknowledge the force of counterarguments while preserving continuity. In a concluding section we reflect critically on the use of these continuity markers with regard to four pragmatic functions that they potentially serve: to specify and clarify argumentative standpoints, to acknowledge a presumption of standpoint continuity, to acknowledge a normative expectation that discussion participants should have standpoints, and to avoid overt disagreement while saving face.

In 2017, Empedocles: European Journal for the Philosophy of Communication published an article by Adrian Pablé, an integrationist linguist, which considers the contribution that Roy Harris’ theory of sign can make to communication theory in terms of the constitutive metamodel of communication theory. This brief response to that contribution concludes that integrationism is a useful but limited perspective and that its claim to exclusive validity should be rejected by communication theorists.

In the ‘realist’ view defended by Sánchez and Campos (2009), communication is a biologically based behavioural phenomenon that communication science should endeavour to describe and explain as accurately as possible. Although this rationale for a biological-behavioural science of communication makes sense to me on its own terms, I will argue that an intellectual discipline that intends to cultivate the social practice of communication (i.e., a practical discipline as proposed by Craig 1989) unavoidably confronts normative and interpretive problems of praxis, (...) as well as empirical and technical questions, and cannot, therefore, be reduced to an exclusively biological-behavioral science. Does this argument entail a categorical rejection of epistemological realism? Mats Bergman (2012) has criticized what he sees as my tendency to describe my pragmatist, social constructionist stance in communication theory as if it were incompatible with realism. Referring to the ‘habit-realism’ of Peirce and Dewey, Bergman claims that I don’t necessarily need to reject this broad realism, which can embrace a moderate constructivism. Reflecting on Bergman’s critique, this article reviews his account of habit-realism and considers what difference it would make for a practical discipline of communication to embrace pragmatist realism as opposed to an anti-realist constructivism on the one side, or an anti-constructivist realism like that of Sánchez and Campos on the other.

Past research demonstrates that emotion recognition is influenced by social category cues present on faces. However, little research has investigated whether holistic processing is required to observe these influences of social category information on emotion perception, and no studies have investigated whether different visual sampling strategies (i.e. differences in the allocation of attention to different regions of the face) contribute to the interaction between social cues and emotional expressions. The current study aimed to address this. Participants categorised happy and angry (...) expressions on own- and other-race faces, and male and female faces. In Experiments 1 and 2, holistic processing was disrupted by presenting inverted faces (Experiment 1) or part faces (Experiment 2). In Experiments 3 and 4 participants’ eye-gaze to eye and mouth regions was also tracked. Disrupting holistic processing did not alter the moderating influence of sex and race cues on emotion recognition (Experiments 1, 2, 4). Gaze patterns differed as a function of emotional expression, and social category cues, however, eye-gaze patterns did not reflect response time patterns (Experiments 3 and 4). Results indicate that the interaction between social category cues and emotion does not require holistic processing and is not driven by differences in visual sampling. (shrink)

The world of John Dewey scholarship recently lost one of its most thoughtful contributors, and teachers of all kinds lost one of their most passionate and committed advocates. Philip W. Jackson was born in 1928 in Vineland, New Jersey, a locale known historically for its excellent grape-growing soil and veterinarian Arthur Goldhaft’s famous pledge to “put a chicken in every pot.” Jackson’s adoptive parents were, appropriately enough, chicken farmers, and, as the story goes, they noticed early on his indisputable knack (...) for singing and poetry recitation.

Religious and Ethical Perspectives on Global Migration examines the complicated social ethics of migration in today's world. Editors Elizabeth W. Collier and Charles R.

This article is the lead piece in a special report that presents the results of a bioethical investigation into chimeric research, which involves the insertion of human cells into nonhuman animals and nonhuman animal embryos, including into their brains. Rapid scientific developments in this field may advance knowledge and could lead to new therapies for humans. They also reveal the conceptual, ethical, and procedural limitations of existing ethics guidance for human‐nonhuman chimeric research. Led by bioethics researchers working closely with an (...) interdisciplinary work group, the investigation focused on generating conceptual clarity and identifying improvements to governance approaches, with the goal of helping scholars, funders, scientists, institutional leaders, and oversight bodies (embryonic stem cell research oversight [ESCRO] committees and institutional animal care and use committees [IACUCs]) deliver principled and trustworthy oversight of this area of science. The article, which focuses on human‐nonhuman animal chimeric research that is stem cell based, identifies key ethical issues in and offers ten recommendations regarding the ethics and oversight of this research. Turning from bioethics’ previous focus on human‐centered questions about the ethics of “humanization” and this research's potential impact on concepts like human dignity, this article emphasizes the importance of nonhuman animal welfare concerns in chimeric research and argues for less‐siloed governance and oversight and more‐comprehensive public communication.

This paper challenges the conventional wisdom dominating the social sciences and philosophy regarding temporal discounting, the practice of discounting the value of future utility when making decisions. Although there are sharp disagreements about temporal discounting, a kind of standard model has arisen, one that begins with a normative standard about how we should make intertemporal comparisons of utility. This standard demands that in so far as one is rational one discounts utilities at future times with an exponential discount function. Tracing (...) the justification for this standard through economics, philosophy and psychology, I’ll make what I believe is the best case one can for it, showing how a non-arbitrariness assumption and a dominance argument together imply that discounting ought to be exponential. Ultimately, however, I don’t find the case compelling. Non-exponential temporal discounting is often rational. If this is correct, Instead of trying to ‘fix’ non-exponential discounting because it is irrational and associated with negative life outcomes, we might instead focus attention on why the conditions obtain that make such discounting rational.

Background and objectives: Developmental coordination disorder is a neurodevelopmental motor disorder occurring in 5-6% of school-aged children. It is suggested that children with DCD show deficits in motor learning. Transcranial direct current stimulation enhances motor learning in adults and children but is unstudied in DCD. We aimed to investigate if tDCS, paired with motor skill training, facilitates motor learning in a pediatric sample with DCD.Methods: Twenty-eight children with diagnosed DCD were randomized and placed into a treatment or sham group. Anodal (...) tDCS was applied in conjunction with fine manual training over 5 consecutive days. Children's motor functioning was assessed with the Purdue Pegboard Test and Jebsen-Taylor Hand Function Test at baseline, post-intervention and 6 weeks following intervention. Group differences in rates of motor learning and skill transfer/retention were examined using linear mixed modeling and repeated measures ANOVAs, respectively.Results: There were no serious adverse events or drop-outs and procedures were well-tolerated. Independent of group, all participants demonstrated improved motor scores over the 5 training days [F, p < 0.001, 95% CI ], with no skill decay observed at retention. There was no interaction between intervention group and day [F, p = 0.086, 95% CI ].Conclusion: Children with DCD demonstrate motor learning with long-term retention of acquired skill. Motor cortex tDCS did not enhance motor learning as seen in other populations. Before conclusions of tDCS efficacy can be drawn, additional carefully designed trials with reproducible results are required.Clinical Trial Registration:ClinicalTrials.gov: NCT03453983. (shrink)

The manifest image is teeming with activity. Objects are booming and buzzing by, changing their locations and properties, vivid perceptions are replaced, and we seem to be inexorably slipping into the future. Time—or at least our experience in time— seems a very turbulent sort of thing. By contrast, time in the scientist image seems very still. The fundamental laws of physics don’t differentiate between past and future, nor do they pick out a present moment that flows. Except for a minus (...) sign in the relativistic metric, there are few differences between the temporal and spatial coordinates in natural science. We seem to have, to echo another debate, an “explanatory gap” between time as we find it in experience and as we find it in science. Reconciling these two images of the world is the principal goal of philosophy of time. (shrink)

The United Nations' designation of 1979 as the International Year of the Child marked the first global effort undertaken to heighten awareness of the special needs of children. Activities initiated during this special year were designed to promote purposive and collaborative actions for the benefit of children throughout the world. Michigan State University's celebration of the International Year of the Child was held from Septem ber 1979 through June 1980. A variety of activities focused attention on the multiplicity of factors (...) affecting the welfare of today's children as well as the children of the future. Many people involved with the university were concerned that benefits to children continue beyond the official time allocated to the celebration. The series Child Nurturance is one response to this concern. The first five volumes of Child Nurturance reflect directly the activities held on the Michigan State University campus and consist of original contributions from guest speakers and invited contributors. Subsequent biennial volumes will present original contributions from individuals representing such fields as anthropology, biology, education, human ecology, psychology, philosophy, sociology, and medicine. We hope the material presented in these volumes will promote greater understanding of children and encourage interdisciplinary inquiry into the individual, family, societal and cultural variables which influence their welfare and development. We would. like to express both our thanks and our admiration for who not only typed the camera-ready copy for each of Margaret Burritt the volumes, but also served as general manager of the entire project.

No shield can protect scientific realism from dealing with the quantum measurement problem. One may be able to erect barriers around the observable or classical, preserving a realism about tables, chairs and the like, but there is no safety zone within the quantum realm, the domain of our best physical theory. The upshot is not necessarily that scientific realism is in trouble. That conclusion demands further arguments. The lesson instead may be that scientific realists ought to stake their case on (...) particular interpretations of quantum theory. In any case, the realist can’t ignore the interpretational issues plaguing quantum mechanics. (shrink)

In the semantic literature, there is a class of examples involving anaphora in intensional contexts, i.e. under the scope of modal operators or propositional attitude predicates, which display anaphoric relations that appear at first glance to violate otherwise well-supported generalizations about operator scope and anaphoric potential. In Section 1,I will illustrate this phenomenon, which, for reasons that should become clear below, I call modal subordination; I will develop a general schema for its identification, and show how it poses problems for (...) most theories of scope and anaphoric relations. In Section 2, I will review the main approaches which have been considered in attempting to account for modal subordination and argue that only an approach involving accommodation can account for the full range of examples. The notion of accommodation is due to Lewis, who defines it as follows: If at time t something is said that requires presupposition P to be acceptable, and if P is not presupposed just before t, then - ceteris paribus and within certain limits - presupposition P comes into existence at t.(Lewis 1979: 340) The interesting question, of course, is what the limits on accommodation might be. I believe that the proper account of modal subordination has something to say about this. I will argue this briefly in section 3, where I draw some conclusions and also sketch some ... (shrink)
