HUMAN PHENOTYPIC MORALITY AND THE BIOLOGICAL BASIS FOR KNOWING GOOD

Co‐creating knowledge takes a new approach to human phenotypic morality as a biologically based, human lineage specific (HLS) trait. Authors from very different backgrounds (anthropology and biology, on the one hand, and astronomy, philosophy, and theology, on the other) first review research on the nature and origins of morality using the social brain network, and studies of individuals who cannot “know good” or think morally because of brain dysfunction. They find these models helpful but insufficient, and turn to paleoanthropology, cognitive science, and neuroscience to understand human moral capacity and its origins long ago, in the genus Homo. An unusual narrative capturing “morality in action” takes the reader back 900,000 years, and then the authors analyze the essential features of moral thinking and behavior as expressed by early and later species on our lineage. In what has primarily been the province of philosophers to date, the authors’ morality model is presented for further scientific testing.     

EPIGENETICS,REPRESENTATION, AND SOCIETY

In recent decades, advances in the life sciences have created an unprecedentedly detailed picture of heredity and the formation of the phenotype where clusters of simplistic reductionist and deterministic views and interpretations have begun to lose ground to more complex and holistic notions. The developments in gene regulation and epigenetics have become a vivid emblem of the ongoing ‘softening’ of heredity. Despite this headway, the outlook and rhetoric widely popular in the twentieth century favoring the ‘gene’ in the ‘gene?genetic plasticity?phenotype?environment’ tetrad have not been successfully tackled but continue to exist in parallel with a new, equally monochromatic, viewpoint championing genetic plasticity. An examination of epigenetics and its presentation in the public sphere, open to a conversation with the social disciplines and philosophy, could address this dichotomy and contribute to the discourse. This article outlines key biological aspects of epigenetics and discusses the language, presentation and wider resonance of this field of life science research.     

PANENTHEISM AND THE UNDOING OF DISENCHANTMENT

In this article, I draw on historical and conceptual arguments to show, first, that disenchantment and the influential view of the relationship between science and religion to which disenchantment gives rise are rooted in the metaphysics of theism. I then introduce the alternative metaphysical position of panentheism and identify Jungian psychology as an important, if implicit, mid‐twentieth‐century instance of panentheistic thought. Using the example of Jungian psychology, I demonstrate how the viewpoint of panentheism undoes the implications of disenchantment for the relationship between science and religion, promoting greater opportunities for dialogue and reconciliation between science and religion. I note, however, that these closer relations may depend on understanding science and religion differently from how they are understood under disenchantment. While the original tension between science and religion is eased, another tension—between panentheistic and disenchanted understandings of science and religion—is exposed. I conclude by reflecting on some implications of this discussion for sociology.     

STIRPICULTURE: SCIENCE‐GUIDED HUMAN PROPAGATION AND THE ONEIDA COMMUNITY

Between 1869 and 1879, the communal Christian group the Oneida Community undertook a pioneering eugenics experiment called “stirpiculture” in upstate New York. Stirpiculture resulted in the planned conception, birth, and communal rearing of fifty‐eight children, bred from selected members of the Oneida Community. This article concerns how the Oneida Community's unique approach to religion and science provided the framework for the creation, process, and eventual dissolution of the stirpiculture experiment. The work seeks to expand current understanding of the early history of eugenics in the United States by placing its practice more than two decades earlier than is generally considered. Additionally, this article situates the Community's leader John Humphrey Noyes as an early eugenics and social scientific thinker. Finally, the treatment provides a case study for the transitional period in mid to late nineteenth century America whereby scientific modes of epistemology were accommodated within or supplanted by theological worldviews.     

POETIC NATURALISM: SEAN CARROLL,SCIENCE, AND MORAL OBJECTIVITY

Physicist Sean Carroll has developed a new theory of the fundamental nature of reality, which he calls “Poetic Naturalism,” with the stated goal of developing a theory of what is real that is consistent with the findings of natural science. Carroll claims to prove that morality cannot be seen as objectively true. This essay argues that Carroll's conclusion is not convincing; there is no good reason to reject moral objectivity within a purely naturalistic worldview.     

How Does Explicit Versus Implicit Risk Information Influence Adolescent Risk‐Taking Engagement?

Adolescents have been shown to be more likely to engage in risky behaviors in daily life. Many studies have indicated that adolescents could make advantageous choices when they receive explicit information but could fail to choose advantageously when they are not informed about risks. The current study aimed to examine the influence of explicit risk information (i.e., when risk information is directly available) versus implicit risk information (i.e., when risk information has to be learned from feedback) on risk‐taking engagement, in order to clarify whether the enhanced risk‐taking observed in decision making under ambiguity in adolescents results from either a greater exploration of ambiguous situations (i.e., a higher ambiguity tolerance) or a specific difficulty associated with learning based on previous choices' outcomes. Adolescents and young adults completed a new adaptation of the Balloon Analogue Risk Task. They were required to accumulate as many points as possible by inflating balloons associated with variable break points and avoiding explosions. This adaptation involved a manipulation of the information level with two conditions, an “informed” condition and a “noninformed” condition, in which the participants had to learn the matching of colors with balloons' resistances based on feedback. The results demonstrated that providing explicit risk information allows adolescents to be as efficient as adults at the end of the game. In contrast, adolescents failed to adjust risk‐taking to the balloon resistance in the noninformed condition. These findings critically suggest that this failure reflects a specific impairment of feedback‐based learning ability but not a global excess of risk‐taking during adolescence.

Mirror-drawing skill in children with specific language impairment: Improving generalization by incorporating variability into the practice session

This study aimed to investigate the procedural deficit hypothesis (PDH) in children with specific language impairment (SLI) by using a mirror-drawing task, a sensorimotor adaptation paradigm that does not involve sequence learning and has never before been used in SLI. A total of 30 school-aged children with SLI matched to 30 typically developing (TD) control children had to trace several figures seen only in mirror-reversed view in two practice sessions separated by a one-week interval. Two practice conditions were compared: a constant condition in which children had to trace the same figure throughout the learning trials, and a variable one in which they had to trace different figures in each trial. The results revealed a similar learning pattern between SLI and TD children in both practice conditions, suggesting that initial learning for a non-sequential procedural task is preserved in SLI. However, the children with SLI generalized the mirror-drawing skill in the same way as the TD children only if there was variability in the way the material was trained (variable practice). No significant schedule effects were observed in the control group.     

Defining agency after implicit bias

Recent findings in empirical psychology show that implicit biases can affect behavior in ways that are difficult to control deliberatively. Doris argues that findings like these constitute a threat to agency, if agency is defined as the ability to reflectively, deliberatively direct one’s actions. I argue, however, that implicit biases pose no fundamental threat to agency since they can be brought under indirect deliberative control, whereby deliberative, reflective actions put in place automatic processes that automatically inhibit unwanted biases. Since automatic processes can be thus used to achieve deliberatively, reflectively endorsed goals, agency should be defined as the ability to act in line with reflectively endorsed goals, whether by deliberative or automatic processes.     

Divided attention enhances explicit but not implicit conceptual memory: an item-specific account of the attentional boost effect

The Attentional Boost Effect (ABE) refers to the counterintuitive finding that words encoded with to-be-responded targets in a divided-attention condition are remembered better than words encoded with distractors. Previous studies suggested that the ABE-related enhancement of verbal memory depends upon the activation of abstract lexical representations. In the present study, we extend this hypothesis by embedding it in the context of a broader perspective, which proposes that divided attention in the ABE paradigm affects item-specific, but not relational, processing. To this purpose, we examined the ABE in the matched tasks of category-cued recall (CCRT: explicit memory) and category exemplar generation (CEGT: implicit memory). In addition, study time was varied (500, 1500 or 4000?ms), to further determine whether the attentional boost manipulation could influence late-phase elaborative processing. In agreement with the predictions of the item-specific account, the results showed that exemplars encoded with targets were recalled better than exemplars encoded with distractors in the CCRT, but not in the CEGT. Moreover, performance in the CCRT increased with study time, whereas the size of the ABE-related enhancement tended to decrease, further confirming that this effect hinges upon early phase encoding processes.
