Myotonic dystrophy type 1 (DM1) is considered a progeroid disease (i.e., causing premature aging). This hypervariable disease affects multiple systems, such as the musculoskeletal, central nervous, gastrointestinal, and others. Despite advances in understanding the underlying pathogenic mechanism of DM1, numerous gaps persist in our understanding, hindering elucidation of the heterogeneity and severity of its symptoms. Accumulating evidence indicates that the toxic intracellular RNA accumulation associated with DM1 triggers cellular senescence. These cells are in a state of irreversible cell cycle arrest (...) and secrete a cocktail of cytokines, referred to as a senescence‐associated secretory phenotype (SASP), that can have harmful effects on neighboring cells and more broadly. We hypothesize that cellular senescence contributes to the pathophysiology of DM1, and clearance of senescent cells is a promising therapeutic approach for DM1. We will discuss the therapeutic potential of different senotherapeutic drugs, especially senolytics that eliminate senescent cells, and senomorphics that reduce SASP expression. (shrink)

Three studies examined the co‐existence of natural and supernatural explanations for illness and disease transmission, from a developmental perspective. The participants (5‐, 7‐, 11‐, and 15‐year‐olds and adults; N = 366) were drawn from 2 Sesotho‐speaking South African communities, where Western biomedical and traditional healing frameworks were both available. Results indicated that, although biological explanations for illness were endorsed at high levels, witchcraft was also often endorsed. More important, bewitchment explanations were neither the result of ignorance nor replaced by biological (...) explanations. Instead, both natural and supernatural explanations were used to explain the same phenomena, and bewitchment explanations were highest among adults. Taken together, these data provide insight into how diverse, culturally constructed belief systems about illness co‐exist across development. (shrink)

Reestablishing feelings of control after experiencing uncertainty has long been considered a fundamental motive for human behavior. We propose that rituals (i.e., socially stipulated, causally opaque practices) provide a means for coping with the aversive feelings associated with randomness due to the perception of a connection between ritual action and a desired outcome. Two experiments were conducted (one in Brazil [n = 40] and another in the United States [n = 94]) to evaluate how the perceived efficacy of rituals is (...) affected by feelings of randomness. In a between-subjects design, the Scramble Sentence Task was used as a priming procedure in three conditions (i.e., randomness, negativity, and neutral) and participants were then asked to rate the efficacy of rituals used for problem-solving purposes. The results demonstrate that priming randomness increased participants' perception of ritual efficacy relative to negativity and neutral conditions. Implications for increasing our understanding of the relationship between perceived control and ritualistic behavior are discussed. (shrink)

What explains the unique features of human culture? Culture is not uniquely human, but human culture is uniquely cumulative. Cumulative culture is a product of our collective intelligence and is supported by cognitive processes and learning strategies that enable people to acquire, transform, and transmit information and technologies within and across generations. Technological and social innovations are currently driving unprecedented changes in cultural complexity and diversity. Innovation is a cognitively and socially complex, multistep process that typically requires (cumulative) cultural learning (...) to achieve. I argue that the technological solutions that characterize twenty-first-century innovation can only be explained by understanding both the capacity to learn from and build upon the insights of others and the transmission systems that store the knowledge and technologies of previous generations. Human uniqueness is a product of cumulative cultural learning, transmission, and innovation. (shrink)

Cognitive gadgets are distinctively human cognitive mechanisms – such as imitation, mind reading, and language – that have been shaped by cultural rather than genetic evolution. New gadgets emerge, not by genetic mutation, but by innovations in cognitive development; they are specialised cognitive mechanisms built by general cognitive mechanisms using information from the sociocultural environment. Innovations are passed on to subsequent generations, not by DNA replication, but through social learning: People with new cognitive mechanisms pass them on to others through (...) social interaction. Some of the new mechanisms, like literacy, have spread through human populations, while others have died out, because the holders had more students, not just more babies. The cognitive gadgets hypothesis is developed through four case studies, drawing on evidence from comparative and developmental psychology, experimental psychology, and cognitive neuroscience. The framework employed – cultural evolutionary psychology, a descendant of evolutionary psychology and cultural evolutionary theory – addresses parallel issues across the cognitive and behavioural sciences. In common with evolutionary developmental biology and the extended evolutionary synthesis, cultural evolutionary psychology underlines the importance of developmental processes and environmental factors in the emergence of human cognition. In common with computational approaches, it emphasises the power of general-purpose mechanisms of learning. Cultural evolutionary psychology, however, also challenges use of the behavioural gambit in economics and behavioural ecology, and rejects the view that human minds are composed of “innate modules” or “cognitive instincts.”.

Competing Explanations of Competing Explanations: Accounting for Conflict Between Scientific and Folk ExplanationsThis paper focuses on the level of people’s explanatory reasoning. It examines why laypeople prefer folk explanations of various physical or biological phenomena to alternative, well‐understood scientific explanations. Shtulman and Legare call this psychological phenomenon “explanatory co‐existence.” On the basis of new experimental data, they evaluate two possible accounts of explanatory co‐existence, a theory‐based and an associative account, and argue that a theory‐based account is the better supported.

Dennett, a philosopher, and Griffin, an ethologist, have recently presented influential arguments promoting the extended use of intentional language by students of animal behavior. This essay seeks to elucidate and to contrast the claims made by each of these authors, and to evaluate their proposals primarily from the perspective of a practicing comparative psychologist or ethologist. While Griffin regards intentional terms as explanatory, Dennett assigns them a descriptive function; the issue of animal consciousness is central to Griffin's program and only (...) tangentially related to Dennett's. The philosopher's arguments are founded upon a more coherent metaphysics, but Dennett neglects to substantiate his claim that animal competences can be most readily modelled by artificial intelligence specialists when they are described in intentional terms. Both authors assume that some examples of animal behavior should not be given an intentional characterization, but neither provides adequate guidelines for the identification of cases belonging to this negative set.

The procedures for structuring clinical ethics case reflections in a childhood cancer care setting are presented, including an eight-step model. Four notable characteristics of the procedures are: members of the inter-professional health care team, not external experts, taking a leading role in the reflections; patients or relatives not being directly involved; the model explicitly addressing values and moral principles instead of focussing exclusively on the interests of involved parties; using a case-based (inductive) rather than principle-based (deductive) method. By discusing the (...) advantages and disadvantages of the proposed procedures, our paper aims to contribute to the literature on models and procedures for ethical analysis that can be used in clinical settings. It is suggested that our proposed procedures have some advantageous features when it comes to promoting health care staff’s learning to structure their thinking about ethical issues. (shrink)

Background: Childhood cancer care involves many ethical concerns. Deciding on treatment levels and providing care that infringes on the child’s growing autonomy are known ethical concerns that involve the whole professional team around the child’s care. Objectives: The purpose of this study was to explore healthcare professionals’ experiences of participating in ethics case reflection sessions in childhood cancer care. Research design: Data collection by observations, individual interviews, and individual encounters. Data analysis were conducted following grounded theory methodology. Participants and research (...) context: Healthcare professionals working at a publicly funded children’s hospital in Sweden participated in ethics case reflection sessions in which ethical issues concerning clinical cases were reflected on. Ethical considerations: The children’s and their parents’ integrity was preserved through measures taken to protect patient identity during ethics case reflection sessions. The study was approved by a regional ethical review board. Findings: Consolidating care by clarifying perspectives emerged. Consolidating care entails striving for common care goals and creating a shared view of care and the ethical concern in the specific case. The inter-professional perspectives on the ethical aspects of care are clarified by the participants’ articulated views on the case. Different approaches for deliberating ethics are used during the sessions including raising values and making sense, leading to unifying interactions. Discussion: The findings indicate that ethical concerns could be eased by implementing ethics case reflection sessions. Conflicting perspectives can be turned into unifying interactions in the healthcare professional team with the common aim to achieve good pediatric care. Conclusion: Ethics case reflection sessions is valuable as it permits the discussion of values in healthcare-related issues in childhood cancer care. Clarifying perspectives, on the ethical concerns, enables healthcare professionals to reflect on the most reasonable and ethically defensible care for the child. A consolidated care approach would be valuable for both the child and the healthcare professionals because of the common care goals. (shrink)

Since the BBS article in which Premack and Woodruff (1978) asked “Does the chimpanzee have a theory of mind?,” it has been repeatedly claimed that there is observational and experimental evidence that apes have mental state concepts, such as “want” and “know.” Unlike research on the development of theory of mind in childhood, however, no substantial progress has been made through this work with nonhuman primates. A survey of empirical studies of imitation, self-recognition, social relationships, deception, role-taking, and perspective-taking suggests (...) that in every case where nonhuman primate behavior has been interpreted as a sign of theory of mind, it could instead have occurred by chance or as a product of nonmentalistic processes such as associative learning or inferences based on nonmental categories. Arguments to the effect that, in spite of this, the theory of mind hypothesis should be accepted because it is more parsimonious than alternatives or because it is supported by convergent evidence are not compelling. Such arguments are based on unsupportable assumptions about the role of parsimony in science and either ignore the requirement that convergent evidence proceed from independent assumptions, or fail to show that it supports the theory of mind hypothesis over nonmentalist alternatives. Progress in research on theory of mind requires experimental procedures that can distinguish the theory of mind hypothesis from nonmentalist alternatives. A procedure that may have this potential is proposed. It uses conditional discrimination training and transfer tests to determine whether chimpanzees have the concept “see.” Commentators are invited to identify flaws in the procedure and to suggest alternatives. Key Words: apes; associative learning; concepts; convergence; deception; evolution of intelligence; folk psychology; imitation; mental state attribution; monkeys; parsimony; perspective-taking; primates; role-taking; self-recognition; social cognition; social intelligence; theory of mind.

Background: How well ethical concerns are handled in healthcare is influenced by the ethical climate of the workplace, which in this study is described as workplace factors that contribute to healthcare professionals’ ability to identify and deal with ethical issues in order to provide the patient with ethically good care. Objectives: The overall aim of the study was to describe perceptions of the paediatric hospital ethical climate among healthcare professionals who treat/care for children with cancer. Research design: Data were collected (...) using the Hospital Ethical Climate Survey developed by Olsson as a separate section in a questionnaire. Descriptive statistics were used to analyse perceptions of the ethical climate. Participants and research context: Physicians, nurses and nurse-aides (n = 89) from three paediatric units participated in this study: haematology/oncology, chronic diseases and neurology. Ethical considerations: The study was approved by the regional ethical review board. Findings: Different perceptions of the ethical climate were rated as positive or negative/neutral. Nurses’ ratings were less positive than physicians on all items. One-third of the participants perceived that they were able to practice ethically good care as they believed it should be practised. Discussion: Differences in professional roles, involving more or less power and influence, might explain why physicians and nurses rated items differently. A positive perception of the possibility to practice ethically good care seems to be related to inter-professional trust and listening to guardians/parents. A negative/neutral perception of the possibility to practice ethically good care appears to be influenced by experiences of ethical conflicts as well as a lack of ethical support, for example, time for reflection and discussion. Conclusion: The two-thirds of participants who had a negative/neutral perception of the possibility to practice ethically good care are at risk of developing moral stress. Clinical ethics support needs to be implemented in care where important values are at stake. (shrink)

Cognitive flexibility, the adaptation of representations and responses to new task demands, improves dramatically in early childhood. It is unclear, however, whether flexibility is a coherent, unitary cognitive trait, or is an emergent dimension of task-specific performance that varies across populations with divergent experiences. Three-to 5-year-old English-speaking U.S. children and Tswana-speaking South African children completed two distinct language-processing cognitive flexibility tests: the FIM-Animates, a word-learning test, and the 3DCCS, a rule-switching test. U.S. and South African children did not differ in (...) word-learning flexibility but showed similar age-related increases. In contrast, U.S. preschoolers showed an age-related increase in rule-switching flexibility but South African children did not. Verbal recall explained additional variance in both tests but did not modulate the interaction between population sample (i.e., country) and task. We hypothesize that rule-switching flexibility might be more dependent upon particular kinds of cultural experiences, whereas word-learning flexibility is less cross-culturally variable. (shrink)

Acknowledging the perils of interdisciplinary and applied conversation analysis, this essay argues for clarity in articulating relationships between methods, addressing, in particular, the language used to formulate claims regarding how participants’ post hoc reflections relate to findings from CA analyses.

In recent years, it was notorious the presence of a persistent interpretation of the political field in terms that find in the notion of crisis its main narrative. In order to assess this historical sensitivity ―which is an effect of the rupture of the grand narrative of progress― the analysis of Janet Roitman has been particularly relevant. Her critical perspective on this historical matrix is based on her assumption that such sensitivity leads to a strong paralysis in terms of political (...) agency, mainly through its claim of being the same incarnation of moments of truth. The central aim of this paper is to challenge this interpretation of the narrative of crisis as a case of post-historical meaning through the analysis of the transhumanist philosophy as deployed by Nick Bostrom. It is thanks to the scrutiny of the affective dimension involved in this sort of historical meaning focused in the role played by anxiety, that is possible to explore the kind of agency that may result from this framework.

The nature of the special obligation that a child has towards her parent(s) is widely discussed in Confucianism. It has also received considerable discussion by analytic commentators. This essay compares and contrasts the accounts of filial obligation found in the two philosophical traditions. The analytic writers mentioned above have explored filial obligations by relating them to other special obligations, such as obligations of debt, friendship, or gratitude. I examine these accounts and try to uncover the implicit assumptions therein about the (...) scope and nature of such filial obligations. I then similarly examine Confucian filial obligations (CFOs) by relating them to these other special obligations of debt, gratitude, and so on. My findings are used to highlight crucial differences in the scope and conception of filial obligations in these two traditions. (shrink)

Cognitive Gadgets is a book about the cultural evolution of distinctively human cognitive mechanisms. Responding to commentators with different and broader interests, I argue that intelligent design has been more important in the formation of grist (technologies, practices and ideas) than of mills (cognitive mechanisms), and that embracing genetic accommodation would leave research on the origins of human cognition empirically unconstrained. I also underline the need to assess empirical methods; query the value of theories that merely accommodate existing data; and (...) ask whether acquiring literacy is more laborious than learning to imitate, to talk and to read minds.

Metacognition – the ability to represent, monitor and control ongoing cognitive processes – helps us perform many tasks, both when acting alone and when working with others. While metacognition is adaptive, and found in other animals, we should not assume that all human forms of metacognition are gene-based adaptations. Instead, some forms may have a social origin, including the discrimination, interpretation, and broadcasting of metacognitive representations. There is evidence that each of these abilities depends on cultural learning and therefore that (...) cultural selectionmight shape humanmetacognition. The cultural origins hypothesis is a plausible and testable alternative that directs us towards a substantial new programme of research. (shrink)

Environmental violence takes form of both ‘spectacular’ events, like ecological disasters usually recognised by the general public, and ‘slow violence’, a type of violence that occurs gradually, out of sight and on a long-term scale. Planetary seas and oceans, loaded with cultural meanings of that which ‘hides’ and ‘allows to forget’, are the spaces where such attritional violence unfolds unseen and ‘out of mind’. Simultaneously, conventional concepts of nature and culture, as dichotomous entities, become obsolete. We all inhabit and embody (...) the world differently, as variously situated people, divided by national, sexual, bodily and economic status, and as very variously situated nonhumans in an increasingly anthropogenic world. This chapter focuses on subtle ‘slow violence’ unfolding through the instances of submerged chemical weapons, so-called dead zones, invasive species and high- and low-trophic mariculture in the Baltic and North Sea regions. It zooms in on the select cases of such ‘environed bodies’, their stories of excruciating slow violence and yet also on unexpected encounters with care and hospitality. The aim is to unfold a low-trophic theory for the naturecultural research on violence and care within environmental humanities, and to engage a coexistential ethics of environmental adaptability informed by feminist posthumanities.
