A Jamesian Response to Reductionism in the Neuropsychology of Religious Experience

December 13, 2018 / Mystical experiences, Other substances, Papers, Philosophy, Publications, Religious studies, Sociology, Spirituality / By / ,

Abstract

The neuroscience revolution has revived interpretations of religious experiences as wholly dependent on biological conditions. William James cautioned against allowing such neurological reductionism to overwhelm other useful perspectives. Contemporary psychologists of religion have raised similar cautions, but have failed to engage James as a full conversation partner. In this article, we present a contemporary, applied version of James’s perspective. We clarify the problem by reviewing specific James-like contemporary concerns about reductionism in the neuropsychological study of religion. Then, most centrally, we employ three of James’s conceptual tools—pragmatism, pluralism, and radical empiricism—to moderate contemporary reductionism. Finally, we point to a constructive approach through which neuroscientists might collaborate with scholars in the humanities and psychosocial sciences, which is consistent with our conclusion that it is often no longer fruitful to separate neurobiological studies from studies that are psychosocial or sociocultural.

Abstract

The purpose of this paper is to provide an integrative review and offer novel insights regarding human research with classic psychedelics (classic hallucinogens), which are 5HT2AR agonists such as lysergic acid diethylamide (LSD), mescaline, and psilocybin. Classic psychedelics have been administered as sacraments since ancient times. They were of prominent interest within psychiatry and neuroscience in the 1950s to 1960s, and during this time contributed to the emergence of the field of molecular neuroscience. Promising results were reported for treatment of both end-of-life psychological distress and addiction, and classic psychedelics served as tools for studying the neurobiological bases of psychological disorders. Moreover, classic psychedelics were shown to occasion mystical experiences, which are subjective experiences reported throughout different cultures and religions involving a strong sense of unity, among other characteristics. However, the recreational use of classic psychedelics and their association with the counterculture prompted an end to human research with classic psychedelics in the early 1970s. We review recent therapeutic studies suggesting efficacy in treating psychological distress associated with life-threatening diseases, treating depression, and treating nicotine and alcohol addictions. We also describe the construct of mystical experience, and provide a comprehensive review of modern studies investigating classic psychedelic-occasioned mystical experiences and their consequences. These studies have shown classic psychedelics to fairly reliably occasion mystical experiences. Moreover, classic psychedelic-occasioned mystical experiences are associated with improved psychological outcomes in both healthy volunteer and patient populations. We also review neuroimaging studies that suggest neurobiological mechanisms of psychedelics. These studies have also broadened our understanding of the brain, the serotonin system, and the neurobiological basis of consciousness. Finally, we provide the most comprehensive review of epidemiological studies of classic psychedelics to date. Notable among these are a number of studies which have suggested the possibility that nonmedical naturalistic (non-laboratory) use of classic psychedelics is associated with positive mental health and prosocial outcomes, although it is clear that some individuals are harmed by classic psychedelics in non-supervised settings. Overall, these various lines of research suggest that classic psychedelics might hold strong potential as therapeutics, and as tools for experimentally investigating mystical experiences and behavioral-brain function more generally.

Ayahuasca improves emotion dysregulation in a community sample and in individuals with borderline-like traits

November 7, 2018 / Ayahuasca, Neuroscience, Papers, Psychopharmacology, Psychotherapy, Publications, Sociology / By / , , , , , ,

Abstract

Background

Research suggests that mindfulness-based interventions may improve mindfulness-related capacities (e.g., decentering, non-judging, and non-reacting) and emotion regulation. Previously, our group reported that ayahuasca could be a potential analogue of mindfulness practice. The main aim of the current study was to examine the effects of ayahuasca on emotional regulation and mindfulness-related capacities. Secondarily, we sought to explore the effects of ayahuasca on individuals with borderline personality disorder (BPD) traits.

Method

This is an observational study of 45 volunteers who participated in an ayahuasca session. The volunteers completed various self-report instruments designed to measure emotional dysregulation (Difficulties in Emotion Regulation Scale (DERS)) and mindfulness traits (Five Facet Mindfulness Questionnaire (FFMQ)–Short Form and Experiences Questionnaire (EQ)) prior to and 24 h after the ayahuasca session. The volunteers were divided into two subgroups based on their score on the McLean Screening Instrument for BPD (MSI-BPD). Twelve participants were grouped into the BPD-like traits subgroup while the rest of them were included in the non-BPD-like subgroup. We performed within-subjects and between-group analyses.

Results

Overall, the participants showed significant improvements on the FFMQ subscales observing, acting with awareness, non-judging, and non-reacting and also significantly improved on decentering (EQ scale) and on the DERS subscales emotional non-acceptance, emotional interference, and lack of control. The BPD-like subgroup also showed significant improvements on the DERS subscales emotional interference and lack of control but not in mindfulness capacities.

Conclusions

These findings suggest a potential therapeutic effect for ayahuasca in emotion regulation and mindfulness capacities (including decentering, acceptance, awareness, and sensitivity to meditation practice). Based on these results, we believe that ayahuasca therapy could be of value in clinical populations, such as individuals with BPD, affected by emotion dysregulation.

Dimensions of consciousness and the psychedelic state

Abstract

It has often been suggested in the popular and academic literature that the psychedelic state qualifies as a higher state of consciousness relative to the state of normal waking awareness. This article subjects this proposal to critical scrutiny, focusing on the question of what it would mean for a state of consciousness to be ‘higher’. We begin by considering the contrast between conscious contents and conscious global states. We then review the changes in conscious global state associated with psychedelic drug use, focusing on the effects of two serotonergic hallucinogens: psilocybin and lysergic acid diethylamide. Limiting our review to findings obtained from lab-based experiments and reported in peer-reviewed journals, we prioritize the more common and reliably induced effects obtained through subjective questionnaires and psychophysical measures. The findings are grouped into three broad categories (sensory perception, cognitive function, and experiences of unity) and demonstrate that although certain aspects of consciousness are improved or enhanced in the psychedelic state, many of the functional capacities that are associated with consciousness are seriously compromised. Psychedelic-induced states of consciousness are indeed remarkable in many ways, but it is inappropriate to regard them as ‘higher’ states of consciousness. The fact that psychedelics affect different aspects of consciousness in fundamentally different ways provides evidence against the unidimensional (or ‘level-based’) view of consciousness, and instead provides strong support for a multidimensional conception of conscious states. The final section of the article considers the implications of this analysis for two prominent theories of consciousness: the Global Workspace Theory and Integrated Information Theory.

Psychedelics, Meditation, and Self-Consciousness

Abstract

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.

Legitimate Medicine in the Age of Consumerism

August 21, 2018 / Anthropology, Medicine, Other substances, Papers, Psychiatry, Psychology, Psychotherapy, Publications, Sociology / By /

Abstract

From the opioid epidemic and medical marijuana to abortion restrictions and physician-assisted suicide, disputes over the proper uses of medicine loom large in American life. Nowhere is this conflict more apparent than in federal drug control policy, which is premised on a clear distinction between legitimate “medical” uses and illicit “abuse.” Yet the Controlled Substances Act defines neither of these foundational concepts. While it is tempting to imagine medicine’s scope is limited to treating or preventing disease – rendering nontherapeutic drug use “abuse” – in fact medical practice has always included interventions that are not aimed at healing. This trend has only accelerated as medical practice has become increasingly consumer-oriented. From Adderall to Xanax, patients now routinely seek prescriptions not to treat diagnosable illnesses, but to relieve stress, improve productivity, and otherwise enhance quality of life.

As physicians increasingly prescribe psychoactive drugs to help healthy people obtain desirable mental states, distinguishing legitimate drug use from recreational abuse becomes ever more difficult. Having failed to acknowledge this challenge, the DEA, courts, and scholars have not offered a principled way to make this distinction, rendering drug control policy increasingly incoherent. As a result, doctors face criminal prosecution without clear standards governing prescribing, potentially valuable interventions are arbitrarily barred from the market, and millions seek the benefits of drugs without professional medical guidance to mitigate their risks.

Rather than being limited to therapeutic aims, medicine is better understood as the application of a loosely-defined set of knowledge and interventions that the law entrusts to specific professionals, with accompanying duties to use these tools to benefit patients. Medical practice includes treating and preventing illnesses, but can also include enhancing social and cognitive functioning and promoting the well-being of people whose challenges do not rise to the level of disorders. Discarding a narrow conception of medicine does not require abandoning the enforcement of drug laws or the policing of doctors. But acknowledging the expansiveness of medicine’s domain does argue for clarifying the scope of physicians’ criminal liability and pursuing new strategies for harnessing drugs’ benefits while mitigating their risks.

A Survey of American Psychiatrists' Attitudes Toward Classic Hallucinogens

June 1, 2018 / LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychiatry, Psychology, Psychotherapy, Publications, Safety, Sociology / By / , ,

Abstract

Recent years have seen renewed interest and research about the use of hallucinogens as possible agents in the treatment of psychiatric disorders. However, we are unaware of studies assessing the current attitudes of American psychiatrists regarding hallucinogens. Therefore, we e-mailed surveys to 1000 members of the American Psychiatric Association-250 resident-fellows and 750 attending psychiatrists. The response rate was 32.4%. Respondents tended to perceive hallucinogens as potentially hazardous and appropriately illegal for recreational purposes. However, a large minority expressed optimism about the potential use of hallucinogens for psychiatric treatment. Male and trainee respondents, as compared with female and attending respondents, reported less concern about the risks of hallucinogens and greater optimism about their therapeutic potential. Younger psychiatrists also seemed more optimistic. Optimism among trainees and younger psychiatrists may possibly reflect greater exposure to recent positive publications about hallucinogens and less awareness of more negative past reports.

Are Ecstasy Induced Serotonergic Alterations Overestimated For The Majority Of Users?

May 7, 2018 / MDMA, Papers, Psychology, Publications, Safety, Sociology / By / , ,

Abstract

BACKGROUND:
Neuroimaging studies imply that the regular use of ±3,4-methylenedioxymethamphetamine (MDMA), the major constituent of ecstasy pills, alters the brain’s serotonergic system in a dose-dependent manner. However, the relevance of these findings remains unclear due to limited knowledge about the ecstasy/MDMA use pattern of real-life users.
AIMS:
We examined the representativeness of ecstasy users enrolled in neuroimaging studies by comparing their ecstasy use habits with the use patterns of a large, international sample.
METHODS:
A systematic literature search revealed 10 imaging studies that compare serotonin transporter levels in recreational ecstasy users to matched controls. To characterize the ecstasy use patterns we relied on the Global Drug Survey, the world’s largest self-report database on drug use. The basis of the dose comparison were the Usual Amount (pills/session), Use Frequency (sessions/month) and Dose Intensity (pills/year) variables.
RESULTS:
Both the average Usual Amount (pills/session) and Use Frequency (sessions/month) of neuroimaging study participants corresponded to the top 5-10% of the Global Drug Survey sample and imaging participants, on average, consumed 720% more pills over a year than the Global Drug Survey participants.
CONCLUSIONS:
Our findings suggest that the serotonin brain imaging literature has focused on unusually heavy ecstasy use and therefore the conclusions from these studies are likely to overestimate the extent of serotonergic alterations experienced by the majority of people who use ecstasy.

The epidemiology of 5-methoxy-N, N-dimethyltryptamine (5-MeO-DMT) use: Benefits, consequences, patterns of use, subjective effects, and reasons for consumption

April 30, 2018 / DMT, New substances, Other substances, Papers, Personal development, Psychology, Publications, Safety, Sociology, Spirituality / By / , , , ,

Abstract

Background/aim:

5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a psychoactive compound found in several plants and in high concentrations in Bufo alvarius toad venom. Synthetic, toad, and plant-sourced 5-MeO-DMT are used for spiritual and recreational purposes and may have psychotherapeutic effects. However, the use of 5-MeO-DMT is not well understood. Therefore, we examined patterns of use, motivations for consumption, subjective effects, and potential benefits and consequences associated with 5-MeO-DMT use.

Methods:

Using internet-based advertisements, 515 respondents (Mage=35.4. SD=11.7; male=79%; White/Caucasian=86%; United States resident=42%) completed a web-based survey.

Results:

Most respondents consumed 5-MeO-DMT infrequently (<once/year), for spiritual exploration, and had used less than four times in their lifetime. The majority (average of 90%) reported moderate-to-strong mystical-type experiences (Mintensity=3.64, SD=1.11; range 0–5; e.g., ineffability, timelessness, awe/amazement, experience of pure being/awareness), and relatively fewer (average of 37%) experienced very slight challenging experiences (Mintensity=0.95, SD=0.91; range 0–5; e.g., anxiousness, fear). Less than half (39%) reported repeated consumption during the same session, and very few reported drug craving/desire (8%), or legal (1%), medical (1%), or psychiatric (1%) problems related to use. Furthermore, of those who reported being diagnosed with psychiatric disorders, the majority reported improvements in symptoms following 5-MeO-DMT use, including improvements related to post-traumatic stress disorder (79%), depression (77%), anxiety (69%), and alcoholism (66%) or drug use disorder (60%).

Conclusion:

Findings suggest that 5-MeO-DMT is used infrequently, predominantly for spiritual exploration, has low potential for addiction, and might have psychotherapeutic effects. Future research should examine the safety and pharmacokinetics of 5-MeO-DMT administration in humans using rigorous experimental designs.
