Our sense of self includes awareness of our thoughts and movements, and our control over them. This feeling can be altered or lost in neuropsychiatric disorders as well as in phenomena such as “automatic writing” whereby writing is attributed to an external source. Here, we employed suggestion in highly hypnotically suggestible participants to model various experiences of automatic writing during a sentence completion task. Results showed that the induction of hypnosis, without additional suggestion, was associated with a small but significant (...) reduction of control, ownership, and awareness for writing. Targeted suggestions produced a double dissociation between thought and movement components of writing, for both feelings of control and ownership, and additionally, reduced awareness of writing. Overall, suggestion produced selective alterations in the control, ownership, and awareness of thought and motor components of writing, thus enabling key aspects of automatic writing, observed across different clinical and cultural settings, to be modelled.

Academic integrity establishes a code of ethics that transfers over into the job force and is a critical characteristic in scientists in the twenty-first century. A student’s perception of cheating is influenced by both internal and external factors that develop and change through time. For students, the COVID-19 pandemic shrank their academic and social environments onto a computer screen. We surveyed science students in the United States at the end of their first COVID-interrupted semester to understand how and why they (...) believed their peers were cheating more online during a pandemic. Almost 81% of students indicated that they believed cheating occurred more frequently online than in-person. When explaining why they believed this, students touched on proctoring, cheating influences, and extenuating circumstances due to COVID-19. When describing how they believed cheating occurred more frequently online, students touched on methods for cheating and surreptitious behavior. The student reasonings were associated with four theories that have been used to examine academic dishonesty. Our results can aid institutions in efforts to quell student concerns about their peers cheating during emergencies. Interestingly, most student beliefs were mapped to planned behavior theory while only a few students were mapped to neutralization theory, suggesting it was a novel modality of assessment rather than a pandemic that shaped student perceptions.

In this study we use dual process theory of self-regulation to develop a framework that outlines the mediating and moderating mechanisms explaining the relationship between leader emotional exhaustion and leadership style (transformational leadership and abusive supervision). Using Glomb et al.’s (2011) framework, we identify empathy and negative emotion as mediators that are of particular importance for leaders. In addition, we propose that leader mindfulness moderates these processes to improve leadership style. Using a time-lagged survey of leaders (N = 505) we (...) found that leader empathy and negative emotion mediated the relationships between emotional exhaustion and leadership style. Furthermore, we found that leader mindfulness significantly moderated the indirect effect of leader emotional exhaustion on leadership style through negative emotion. However, leader mindfulness did not moderate the relationship between emotional exhaustion and empathy. Theoretical and practical implications are discussed. (shrink)

Serious ethical violations in medicine, such as sexual abuse, criminal prescribing of opioids, and unnecessary surgeries, directly harm patients and undermine trust in the profession of medicine. We review the literature on violations in medicine and present an analysis of 280 cases. Nearly all cases involved repeated instances of intentional wrongdoing, by males in nonacademic medical settings, with oversight problems and a selfish motive such as financial gain or sex. More than half of cases involved a wrongdoer with a suspected (...) personality disorder or substance use disorder. Despite clear patterns, no factors provide readily observable red flags, making prevention difficult. Early identification and intervention in cases requires significant policy shifts that prioritize the safety of patients over physician interests in privacy, fair processes, and proportionate disciplinary actions. We explore a series of 10 questions regarding policy, oversight, discipline, and education options. Satisfactory answers to these questions will require input from diverse stakeholders to help society negotiate effective and ethically balanced solutions. (shrink)

Traditional engineering courses typically approach teaching and problem solving by focusing on the physical dimensions of those problems without consideration of dynamic social and ethical dimensions. As such, projects can fail to consider human rights, community questions and concerns, broader impacts upon society, or otherwise result in inequitable outcomes. And, despite the fact that students in engineering receive training on the Professional Code of Ethics for Engineers, to which they are expected to adhere in practice, many students are unable to (...) recognize and analyze real-life ethical challenges as they arise. Indeed, research has found that students are typically less engaged with ethics—defined as the sensitivity and judgment of microethics and macroethics, sensitivity to diversity, and interest in promoting organizational ethical culture—at the end of their engineering studies than they were at the beginning. As such, many studies have focused on developing and improving the curriculum surrounding ethics through, for instance, exposing students to ethics case studies. However, such ethics courses often present a narrow and simplified view of ethics that students may struggle to integrate with their broader experience as engineers. Thus, there is a critical need to unpack the complexity of ethical behavior amongst engineering students in order to determine how to better foster ethical judgment and behavior. Promoting ethical behavior among engineering students and developing a culture of ethical behavior within institutions have become goals of many engineering programs. Towards this goal, we would like to present an overview of the current scholarship of engineering ethics and propose a theoretical framework of ethical behavior using a review of articles related to engineering ethics from 1997-2020. The review engages in theories across disciplines including philosophy, education, and psychology. In this work-in-progress paper, we present a subset of initial results based on a review of the first 50 articles out of the systematically selected 409 articles from Springer, Engineering Village, and EBSCO-Education Full Text. Preliminary results identify two major kinds of drivers of ethical behavior, namely individual level ethical behavior drivers and institutional drivers. Our preliminary results indicate that a sensitivity to both microethics and macroethics as well as the implicit and explicit understanding of ethics are essential in promoting ethical behavior amongst students. Furthermore, while drivers of ethical behavior at the individual level is important, one should not ignore the roles of the drivers of ethical behavior at the institutional level in promoting a collective ethical culture within organizations. The review also points to a need to focus on increasing students’ macroethical sensitivity to topics such as sustainability and protection of human rights. This research thus addresses the need, driven by existing scholarship, 2 to identify a conceptual framework for explaining how ethical judgment and behavior in engineering can be further promoted.

Engineering ethics can be divided into three spheres, namely the technical, the professional, and the social. Ideally, engineering students should engage with all three spheres of ethics, but the literature suggests that this might not be the case. How do engineering students engage with the three spheres of engineering ethics during a global pandemic? The COVID-19 pandemic represents a dramatic and ongoing real-world challenge affecting many students personally. This research explores the extent to which engineering students engage with each sphere (...) of engineering ethics by examining how engineering students understand their roles in addressing the pandemic and its implications. We conducted a survey with undergraduate engineering students (n = 410) at a university in the Midwest. Qualitative analysis suggests that there was low engagement with both social ethics and professional ethics among respondents, while there was higher engagement with technical ethics. Quantitative analysis suggests that non-conservative engineering students from less wealthy families in our study show higher engagement with technical ethics as compared to conservative engineering students from less wealthy families. Non-conservative engineering students from wealthy families, however, show similar engagement with technical ethics as compared to conservative engineering students from wealthy families. In addition, engineering students from both wealthy and less wealthy families show higher engagement with technical ethics if they reside in urban areas as compared to engineering students from both wealthy and less wealthy families in non-urban areas. In addition, the difference in terms of engagement with technical ethics between non-urban engineering students from less wealthy families and urban engineering students from less wealthy families is larger than the difference in terms of engagement with technical ethics between non-urban engineering students from wealthy families and urban engineering students from wealthy families. Further investigation will be needed to explain these findings. However, qualitative results confirm that, despite the potential for the pandemic to encourage engagement with all three spheres of ethics, there continues to be low engagement with ethics beyond the technical level.

In evolutionary biology changes in population structure are explained by citing trait fitness distribution. I distinguish three interpretations of fitness explanations—the Two‐Factor Model, the Single‐Factor Model, and the Statistical Interpretation—and argue for the last of these. These interpretations differ in their degrees of causal commitment. The first two hold that trait fitness distribution causes population change. Trait fitness explanations, according to these interpretations, are causal explanations. The last maintains that trait fitness distribution correlates with population change but does not cause (...) it. My defense of the Statistical Interpretation relies on a distinctive feature of causation. Causes conform to the Sure Thing Principle. Trait fitness distributions, I argue, do not. *Received July 2009; revised October 2009. †To contact the author, please write to: Department of Philosophy/Institute for the History, Philosophy of Science and Technology, University of Toronto, Victoria College, 91 Charles Street West, Toronto, ON M5S 1K7, Canada; e‐mail: denis.walsh@utoronto.ca.

We distinguish dynamical and statistical interpretations of evolutionary theory. We argue that only the statistical interpretation preserves the presumed relation between natural selection and drift. On these grounds we claim that the dynamical conception of evolutionary theory as a theory of forces is mistaken. Selection and drift are not forces. Nor do selection and drift explanations appeal to the (sub-population-level) causes of population level change. Instead they explain by appeal to the statistical structure of populations. We briefly discuss the implications (...) of the statistical interpretation of selection for various debates within the philosophy of biologythe `explananda of selection' debate and the `units of selection' debate.

The spacing effect is among the most widely replicated empirical phenomena in the learning sciences, and its relevance to education and training is readily apparent. Yet successful applications of spacing effect research to education and training is rare. Computational modeling can provide the crucial link between a century of accumulated experimental data on the spacing effect and the emerging interest in using that research to enable adaptive instruction. In this paper, we review relevant literature and identify 10 criteria for rigorously (...) evaluating computational models of the spacing effect. Five relate to evaluating the theoretic adequacy of a model, and five relate to evaluating its application potential. We use these criteria to evaluate a novel computational model of the spacing effect called the Predictive Performance Equation. Predictive Performance Equation combines elements of earlier models of learning and memory including the General Performance Equation, Adaptive Control of Thought—Rational, and the New Theory of Disuse, giving rise to a novel computational account of the spacing effect that performs favorably across the complete sets of theoretic and applied criteria. We implemented two other previously published computational models of the spacing effect and compare them to PPE using the theoretic and applied criteria as guides. (shrink)

According to historical theories of biological function, a trait's function is determined by natural selection in the past. I argue that, in addition to historical functions, ahistorical functions ought to be recognized. I propose a theory of biological function which accommodates both. The function of a trait is the way it contributes to fitness and fitness can only be determined relative to a selective regime. Therefore, the function of a trait can only be specified relative to a selective regime. Apart (...) from its desirable pluralism, only this view of relational function can support the function/accident and function/malfunction distinctions commonly thought to be part of the concept of function. Furthermore, only relational function correctly characterizes the explanatory consequences of function attributions in evolutionary biology. (shrink)

To function well in an unpredictable environment using unreliable components, a system must have a high degree of robustness. Robustness is fundamental to biological systems and is an objective in the design of engineered systems such as airplane engines and buildings. Cognitive systems, like biological and engineered systems, exist within variable environments. This raises the question, how do cognitive systems achieve similarly high degrees of robustness? The aim of this study was to identify a set of mechanisms that enhance robustness (...) in cognitive systems. We identify three mechanisms that enhance robustness in biological and engineered systems: system control, redundancy, and adaptability. After surveying the psychological literature for evidence of these mechanisms, we provide simulations illustrating how each contributes to robust cognition in a different psychological domain: psychomotor vigilance, semantic memory, and strategy selection. These simulations highlight features of a mathematical approach for quantifying robustness, and they provide concrete examples of mechanisms for robust cognition. (shrink)

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

The central insight of Darwin's Origin of Species is that evolution is an ecological phenomenon, arising from the activities of organisms in the 'struggle for life'. By contrast, the Modern Synthesis theory of evolution, which rose to prominence in the twentieth century, presents evolution as a fundamentally molecular phenomenon, occurring in populations of sub-organismal entities - genes. After nearly a century of success, the Modern Synthesis theory is now being challenged by empirical advances in the study of organismal development and (...) inheritance. In this important study, D. M. Walsh shows that the principal defect of the Modern Synthesis resides in its rejection of Darwin's organismal perspective, and argues for 'situated Darwinism': an alternative, organism-centred conception of evolution that prioritises organisms as adaptive agents. His book will be of interest to scholars and advanced students of evolutionary biology and the philosophy of biology. (shrink)

Singles are an understudied yet growing segment of the adult population. The current study aims to expand the lens of relationship science by examining the well-being of unpartnered, single adults using latent profile analysis. We recruited singles closely matched to the United States census for an exploratory cross-sectional survey using five variables that strongly predict well-being. All five variables significantly predicted life satisfaction for the full sample. Latent profile analyses detected 10 groups of singles. Half of the profiles were happy (...) and half of the profiles were unhappy. Each profile had its own unique patterns relating to personal relationships, self-esteem, and personality traits. The happiest profile had the best relationships, self-esteem, and personality, while the unhappiest profile had the worst relationships, self-esteem, and personality. The profiles in between these two extremes had more nuanced patterns. For example, one relatively happy profile in the middle had high friendship satisfaction but low family satisfaction, while an adjacent profile showed the opposite pattern. Overall, singles who had positive relationships—both with themselves and others—were happiest. (shrink)

The Units of Selection debate is a dispute about the causes of population change. I argue that it is generated by a particular `dynamical'' interpretation of natural selection theory, according to which natural selection causes differential survival and reproduction of individuals and natural selection explanations cite these causes. I argue that the dynamical interpretation is mistaken and offer in outline an alternative, `statistical'' interpretation, according to which natural selection theory is a fancy kind of `bookkeeping''. It explains by citing the (...) statistical structure of a population and not by citing the causes of survival and reproduction. From the perspective of the statistical interpretation there is no substantive Units of Selection issue. (shrink)

I argue that recent advances in developmental biology demonstrate the inadequacy of suborganismal mechanism. The category of the organism, construed as a ’natural purpose’ should play an ineliminable role in explaining ontogenetic development and adaptive evolution. According to Kant the natural purposiveness of organisms cannot be demonstrated to be an objective principle in nature, nor can purposiveness figure in genuine explain. I attempt to argue, by appeal to recent work on self-organization, that the purposiveness of organisms is a natural phenomenon (...) and, by appeal to the apparatus of invariance explanation, that biological purposiveness provides genuine, ineliminable biological explanations.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

There are two general approaches to characterising biological functions. One originates with Cummins. According to this approach, the function of a part of a system is just its causal contribution to some specified activity of the system. Call this the ‘C-function’ concept. The other approach ties the function of a trait to some aspect of its evolutionary significance. Call this the ‘E-function’ concept. According to the latter view, a trait's function is determined by the forces of natural selection. The C-function (...) and E-function concepts are clearly quite different, but there is an important relation between them which heretofore has gone unnoticed. The purpose of this paper is to outline that relation.This is not the first paper to discuss the relation of C-function and E-function. Previous attempts all follow either one of two strategies. The first proposes that the two concepts are ‘unified.’ The other proposes that they are radically distinct and apply to wholly different fields within biology. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Editors’ NoteJames M. DuBois, Ana S. Iltis, and Heidi A. WalshFrom childhood, David Slakter had undergone tests and invasive procedures to monitor his nephritis. It was not a surprise when in 2015, doctors told him he needed a kidney transplant. The wife of a childhood friend was a close match and gave him one of her kidneys. Before his transplant, aerobic exercise was difficult; a few months after transplant, (...) Slakter could ride his bike, hike, and work out with a personal trainer. He no longer had to weigh food or gauge his potassium consumption, a concern for people with kidney failure. For Slakter, “life post-transplant has been a significant improvement.”Individuals or family members of those who have received an organ transplant from a living or deceased donor share their stories in this issue of Narrative Inquiry in Bioethics. The symposium is titled “Receiving the Gift of Life: Stories from Organ Transplant Recipients.” Organ transplantation can extend an individual’s life by decades. It can also greatly improve an individual’s quality of life, as was Slakter’s experience. At the same time, organ transplantation is expensive and stressful. Recipients can experience complications, including organ rejection, and there are few appealing alternatives.After her heart transplant, author Leilani R. Graham required four open-heart surgeries, ECMO, and an intra-aortic balloon pump. She experienced delirium, necrotizing pneumonia, and severe muscular atrophy that required her to re-learn how to walk. She struggled with weight gain, explosive mood swings, hair loss, and was terrified that her body would reject the new heart. For Graham, “[Transplant] was not the miracle [she] was hoping for.” Graham says she felt unprepared for and inadequately informed about what to expect after her transplant, which left her “battered, beaten, and bruised” with a 12-inch line from neck to navel and “bullet holes” up and down her torso from the chest tubes. When reflecting on her experience post-transplant, Graham says, “It wasn’t the physical trauma that hurt the most. It was that no one seemed surprised [by the aftereffects of transplant].” Seemingly no one, that is except Graham, who calls on transplant providers to “prioritize empathy.”The symposium editors are Jason T. Eberl and Tristan McIntosh. Three commentary articles, written by Macey Leigh Levan, Heather Lannon, and Vidya A. Fleetwood, Roslyn B. Mannon & Krista L.

Pearlman. The relief of suffering is a primary goal of medicine. However, the authors note that clinicians often miss or ignore suffering because they focus on the causes rather than the experience of suffering, or the subjective nature of suffering makes it difficult to discuss. The authors believe that “the key to communicating about suffering lies in finding [End Page vii] the right kind of words to describe the experience” and say that figurative language offers a promising approach. In their research, the authors performed qualitative analysis on 52 works of literature and identified 254 excerpts of figurative language with themes of non-physical or psychological suffering. The authors found 13 salient themes: brokenness, diminishment, disorientation, drowning, emptiness, imprisonment, battle, darkness, isolation, invisibility, lifelessness, punishment, and torture. The authors reiterate that developing a shared language of suffering could foster a therapeutic patient-clinician relationship and improve clinicians’ ability to recognize and address a patient’s experience of suffering.María Susana Ciruzzi wrote the first of two case studies included in this issue. “The Sword of King Solomon” addresses a tragic and difficult subject—how to navigate the situation posed by conjoined twins when “any decision will produce damage and suffering.” The case involves two infant male patients born at 37 weeks gestation as omphalo-ischiopagus conjoined twins...

There are two competing interpretations of the modern synthesis theory of evolution: the dynamical (also know as ‘traditional’) and the statistical. The dynamical interpretation maintains that explanations offered under the auspices of the modern synthesis theory articulate the causes of evolution. It interprets selection and drift as causes of population change. The statistical interpretation holds that modern synthesis explanations merely cite the statistical structure of populations. This paper offers a defense of statisticalism. It argues that a change in trait frequencies (...) in a population can be attributed only to selection or drift against the background of a particular statistical description of the population. The traditionalist supposition that selection and drift are description‐independent causes of population change leads the dynamical interpretation into a dilemma: it must face a contradiction or accept the loss of explanatory power.

Hierarchical Bayesian models provide an account of Bayesian inference in a hierarchically structured hypothesis space. Scientific theories are plausibly regarded as organized into hierarchies in many cases, with higher levels sometimes called ‘paradigms’ and lower levels encoding more specific or concrete hypotheses. Therefore, HBMs provide a useful model for scientific theory change, showing how higher-level theory change may be driven by the impact of evidence on lower levels. HBMs capture features described in the Kuhnian tradition, particularly the idea that higher-level (...) theories guide learning at lower levels. In addition, they help resolve certain issues for Bayesians, such as scientific preference for simplicity and the problem of new theories. (shrink)

When I say ‘pain’, it is clearly a singular phenomenon. Yet if I ask for an example, you can provide many varying instances that confound the idea of its singularity. How can a pinprick be of the same thing as depression or grief? This study maintains the singularity of pain by exploring the process and structure of its experience to account for its variance and its subjectivity. Heidegger’s Being and Time provides the pathway to achieving this, where we comprehend how (...) pain’s myriad manifestations, and their inherent subjectivity, relate to our way of Being – the meaningful horizon through which we encounter pain. The study comes to tie the process of encountering pain with a structure that suffering provides, which explains both the variance and the subjectivity of the pain experience. This can then be mapped onto individual experiences of a singular phenomenon to understand how they arose and what has conditioned them. (shrink)

While French biologists were turning a cold shoulder to On the Origin of Species in the 1860s, Charles Darwin was earnestly pursuing a professional connection with one French physiologist in particular: Charles Brown-Séquard. Darwin had been closely following Brown-Séquard’s startling experiments on guinea pigs, which demonstrated that experimentally induced epilepsy could pass from parent to offspring. In Darwin’s mind, Brown-Séquard had produced the most convincing evidence to date that acquired traits could be inherited. Darwin saw opportunities in Brown-Séquard and his (...) work. If Brown-Séquard realized the evolutionary implications of his experiments, and then endorsed the Origin in Paris, Darwin could be well on his way to securing a French audience for his theories. Darwin quickly mobilized his powers of correspondence to make this French connection, but Brown-Séquard received Darwin’s advances with caution. A connection with Darwin could be useful in London and America, where he was increasingly spending time, but to publicly support Darwin would be professionally damaging back home in Paris. This paper examines the dance of letters between Darwin and Brown-Séquard, the politics of citation, and the delicacy of sustaining a transnational biological career between France and Britain in the 1860s. This paper casts a new perspective on an old debate in the history of biology. I show that from within the “heavy cloud” of anti-evolutionary thought in France, there existed a live wire between Brown-Séquard and Darwin. I argue that British evolutionary theory in the age of Darwin was built, in part, with French participation. (shrink)
