In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been made (...) at bridging these two domains of inquiry, despite intriguing evidence of overlap between the phenomenology and neurophysiology of meditation practice and psychedelic states. In particular, many contemplative traditions explicitly aim at dissolving the sense of self by eliciting altered states of consciousness through meditation, while classical psychedelics are known to produce significant disruptions of self-consciousness, a phenomenon known as drug-induced ego dissolution. In this article, we discuss available evidence regarding convergences and differences between phenomenological and neurophysiological data on meditation practice and psychedelic drug-induced states, with a particular emphasis on alterations of self-experience. While both meditation and psychedelics may disrupt self-consciousness and underlying neural processes, we emphasize that neither meditation nor psychedelic states can be conceived as simple, uniform categories. Moreover, we suggest that there are important phenomenological differences even between conscious states described as experiences of self-loss. As a result, we propose that self-consciousness may be best construed as a multidimensional construct, and that “self-loss,” far from being an unequivocal phenomenon, can take several forms. Indeed, various aspects of self-consciousness, including narrative aspects linked to autobiographical memory, self-related thoughts and mental time travel, and embodied aspects rooted in multisensory processes, may be differently affected by psychedelics and meditation practices. Finally, we consider long-term outcomes of experiences of self-loss induced by meditation and psychedelics on individual traits and prosocial behavior. We call for caution regarding the problematic conflation of temporary states of self-loss with “selflessness” as a behavioral or social trait, although there is preliminary evidence that correlations between short-term experiences of self-loss and long-term trait alterations may exist.

Can the use of psychedelic drugs induce lasting changes in metaphysical beliefs? While it is popularly believed that they can, this question has never been formally tested. Here we exploited a large sample derived from prospective online surveying to determine whether and how beliefs concerning the nature of reality, consciousness, and free‑will, change after psychedelic use. Results revealed significant shifts away from ‘physicalist’ or ‘materialist’ views, and towards panpsychism and fatalism, post use. With the exception of fatalism, these changes endured (...) for at least 6 months, and were positively correlated with the extent of past psychedelic‑use and improved mental‑health outcomes. Path modelling suggested that the belief‑shifts were moderated by impressionability at baseline and mediated by perceived emotional synchrony with others during the psychedelic experience. The observed belief‑shifts post‑psychedelic‑use were consolidated by data from an independent controlled clinical trial. Together, these findings imply that psychedelic‑use may causally influence metaphysical beliefs—shifting them away from ‘hard materialism’. We discuss whether these apparent effects are contextually independent. (shrink)

Acute exercise consistently benefits both emotion and cognition, particularly cognitive control. We evaluated acute endurance exercise influences on emotion, domain-general cognitive control, and the cognitive control of emotion, specifically cognitive reappraisal. Thirty-six endurance runners, defined as running at least 30 miles per week with one weekly run of at least 9 miles (21 female, age 18-30 years) participated. In a repeated measures design, participants walked at 57% age-adjusted maximum heart rate (HRmax) (range 51-63%) and ran at 70% HRmax (range 64-76%) (...) for 90 minutes on two separate days. Participants completed measures of emotional state and the Stroop test of domain-general cognitive control before, every 30 minutes during, and 30 minutes after exercise. Participants also completed a cognitive reappraisal task after exercise. Functional near-infrared spectroscopy tracked changes in oxygenated and deoxygenated hemoglobin levels in the prefrontal cortex (PFC). Endurance exercise elevated positive emotion and cognitive reappraisal success. Endurance exercise reduced Stroop response time and test-evoked PFC oxygenation during exercise. Results suggest that even at relatively moderate intensities, endurance athletes benefit emotionally from running both during and after exercise, and task-related prefrontal cortex oxygenation reductions do not appear to hinder prefrontal-dependent cognitive control.

"In this paper, I explore the ways that phenomenological concepts like intercorporeality and mutual incorporation offer new tools in trying to make sense of human experiences via mediating systems. In particular, I think about how the COVID-19 pandemic hastened a large population into mediated interactions, and what is lost, perhaps contingently or perhaps intrinsically, when human experiences are mediated in this way. I look to research in presence, skillful interaction, and enactive social cognition to argue that there remains something ineffable (...) or at least extremely hard to pin down about intercorporeality, and embodied togetherness has not yet been replicated in the mediating systems we currently embrace. Keywords: intercorporeality, participatory sense-making, mediating technologies, presence. ". (shrink)

Appraisal research based on participants' self-report of emotional experiences is predicated on the assumption that the academic community and the lay public share comparable meanings of the emotion terms used. However, this can be a risky assumption to make, as in the case of the emotion disgust which appears in common usage to reflect irritation, or anger, as often as repulsion. To examine the theoretical versus the lay meaning of disgust, 140 undergraduates were asked to recall a time when they (...) felt either angry, disgust, disgusted, revulsion, or grossed out. Analysis of event recall responses and emotional experience measures suggests that the common understanding of the word disgust reflects a combination of the conceptual meanings of disgust and anger whereas the slang term grossed out more closely captures the theoretical construct of disgust. Implications of these findings for emotion research based on self-report are discussed. (shrink)

Emotional memories are vivid and lasting but not necessarily accurate. Under some conditions, emotion even increases people’s susceptibility to false memories. This review addresses when and why emotion leaves people vulnerable to misremembering events. Recent research suggests that pregoal emotions—those experienced before goal attainment or failure —narrow the scope of people’s attention to information that is central to their goals. This narrow focus can impair memory for peripheral details, leaving people vulnerable to misinformation concerning those details. In contrast, postgoal emotions—those (...) experienced after goal attainment or failure —broaden the scope of attention leaving people more resistant to misinformation. Implications for legal contexts, such as emotion-related errors in eyewitness testimony, are discussed. (shrink)

Notions of human nature and what is natural are vague and contradictory within the field of bioethics, especially evident through individuals critical of bodily diversity through nanobiology and biotechnology in general. This paper discusses the paradoxical aspects of these notions of human nature, while showing that they rely on a notion of a standard body that all humans allegedly share. I examine several writings on biotechnology by bioethicists, specifically by people working in policy—it is here that the normativity of human (...) nature becomes a pressing concern. Once it has been shown that there is no standard body, and indeed typical bioethical notions of human nature are internally contradictory, a more productive conversation can be engaged in that allows for morphological diversity, be it through biotechnological change or via nature itself.

Cognitive science is undergoing a rebirth, overturning much of the traditional thought established by people like Chomsky and Newell and Simon. This second-generation thought, exemplified by people like Clark, Lakoff, and Johnson, is pursuing the same project as the traditional thinkers, but with evolutionary considerations. This revision of cognitive science can trace its roots back to the American Pragmatists, while still attending to even the most recent work in neuroscience and evolutionary psychology. If one takes this embodied, evolutionary story seriously, (...) we can eliminate many of the oppressive problems that plague cognitive science, including those surrounding qualia, intelligence, and even consciousness.

Our human forms of embodiment, the many various ways real bodies appear in the real world, structure our experiences, memories, thoughts, and language in ways both subtle and important. On The Good Place, we have bodies in the afterlife, and they must be real enough that they can be filled with pins and butthole spiders. Researchers recognized the importance of having a body in the real world as a method of building artificial intelligence (AI). Throughout the first three seasons of (...) The Good Place, Janet herself recognizes the ways she is changing. The change is subtle early on, so it's easy to continue to see her as the Busty Alexa that Eleanor sees at first. Janet is a refreshing way to think about AI going forward. She is a model for how AI researchers ought to think about the emergence of mind, thoughts and feelings that a system previously lacked.

The recent proposal by Douglas and Savulescu for an ethics of knowledge provokes a renewed consideration of an enduring issue. Yet, the concept raises significant challenges for procedural and substantive justice. Indeed, the operationalisation of ‘an ethics of knowledge’ could be as alarming as what it seeks to prevent. While we can acknowledge that there is, and surely always will be, potential for misuse of beneficial science and technology, a contemplated conception of what we ought to not know, devise or (...) disseminate sets before us an enormously complex task. This essay challenges an ethics of knowledge to respond to concerns of procedural and substantive justice. While the concept has a certain appeal, it does not appear to adequately address certain fundamental issues as it is currently presented. Here, the author invites consideration of two primary points: (1) who should decide, based on whose interests? and (2) could such an exercise actually be effective in achieving its goal? (shrink)

The primary purpose of this study was to better understand the effects of consumers' perceived self-efficacy on their perceptions of the ethicality of a fear appeal and subsequent attitudes towards the ad, the brand, and purchase intentions. In this study, a total of 305 consumer responses were investigated to determine attitudes toward a fear appeal ad. The results suggest that the use of strong fear appeals may not be perceived as unethical if consumers feel they can use the recommended product (...) to effectively eliminate the threat posed by the ad.

The benefits of homeschooling are now protected through legalization of the practice. Most of its harms could be prevented through its responsible regulation.

A notion of factorizability for vector-valued measures on a quantum logic L enables us to pass from abstract logics to Hilbert space logics and thereby to construct tensor products. A claim by Kruszynski that, in effect, every orthogonally scattered measure is factorizable is shown to be false. Some criteria for factorizability are found.

This article presents the results of a study that analysed whether social responsibility had any bearing on the decision making of institutional investors. Being that institutional investors prefer socially aligned organizations, this study explored to what extent the corporate actions and/or social/environmental investments influenced their decisions. Our results suggest that there are specific variables that affect the perceived value of the organization, leading to decisions to not only invest, but whether to hold or sell the shares, and therefore having a (...) consequential impact on the capital market’s valuation.

This book focuses on major educational philosophies impacting Western education and makes sense of past and current trends placed in historical context. This third edition is updated with the swift changes taking place in education and looks at postmodernism as it has continued to develop during the past fifty years.

The present study investigated the respective roles of withdrawal, language, and context-inappropriate anger in the development of emotion knowledge among a subsample of 4 and 5 year-old preschoolers. Measures included parent-reported withdrawn behavior, externalizing behavior, and CI anger, as well as child assessments of receptive language and EK. Ultimately, findings demonstrated that receptive language mediated the relationship between withdrawn behavior and situational EK. However, CI anger significantly interacted with receptive language, and, when incorporated into a second-stage moderated mediation analysis, moderate (...) levels of CI anger rendered the indirect effect of withdrawn behavior on situational EK via receptive language insignificant. Cumulatively, these findings demonstrate a mechanism by which withdrawal may impact EK. They also indicate that such an effect may be attenuated in children with moderate levels of CI anger. Implications of these findings are discussed. (shrink)
