There has been a growing interest in research concerning memory modification technologies (MMTs) in recent years. Neuroscientists and psychologists are beginning to explore the prospect of controllable and intentional modification of human memory. One of the technologies with the greatest potential to this end is optogenetics—an invasive neuromodulation technique involving the use of light to control the activity of individual brain cells. It has recently shown the potential to modify specific long-term memories in animal models in ways not yet possible (...) with other MMTs. As the therapeutic potential of optogenetics has already prompted approval of the first human trials, it is especially important and timely to consider the opportunities and dangers this technology may entail. In this article, we focus on possible consequences of optogenetics as an MMT by analyzing fundamental threats potentially associated with memory modifications: the potential disruption of personality and authenticity.

Throughout the twentieth century, the automation of formal logics in computers has created unprecedented potential for practical applications of logic—most prominently the mechanical verification of mathematics and software. But the high cost of these applications makes them infeasible but for a few flagship projects, and even those are negligible compared to the ever-rising needs for verification. One of the biggest challenges in the future of logic will be to enable applications at much larger scales and simultaneously at much lower costs. (...) This will require a far more efficient allocation of resources. Wherever possible, theoretical and practical results must be formulated generically so that they can be instantiated to arbitrary logics; this will allow reusing results in the face of today’s multitude of application-oriented and therefore diverging logical systems. Moreover, the software engineering problems concerning automation support must be decoupled from the theoretical problems of designing logics and calculi; this will allow researchers outside or at the fringe of logic to contribute scalable logic-independent tools. Anticipating these needs, the author has developed the Mmt framework. It offers a modern approach towards defining, analyzing, implementing, and applying logics that focuses on modular design and logic-independent results. This paper summarizes the ideas behind and the results about Mmt. It focuses on showing how Mmt. provides a theoretical and practical framework for the future of logic. (shrink)

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and dangers (...) such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

For nearly two decades, ethicists have expressed concerns that the further development and use of memory modification technologies (MMTs)—techniques allowing to intentionally and selectively alter memories—may threaten the very foundations of who we are, our personal identity, and thus pose a threat to our well-being, or even undermine our “humaneness.” This paper examines the potential ramifications of memory-modifying interventions such as changing the valence of targeted memories and selective deactivation of a particular memory as these interventions appear to be at (...) the same time potentially both most promising clinically as well as menacing to identity. However, unlike previous works discussing the potential consequences of MMTs, this article analyzes them in the context of the narrative relational approach to personal identity and potential issues related to autonomy. I argue that such a perspective brings to light the ethical aspects and moral issues arising from the use of MMTs that have been hidden from previously adopted approaches. In particular, this perspective demonstrates how important the social context in which an individual lives is for the ethical evaluation of a given memory-modifying intervention. I conclude by suggesting that undertaking memory modifications without taking into account the social dimension of a person’s life creates the risk that she will not be able to meet one of the basic human needs—the autonomous construction and maintenance of personal identity. Based on this conclusion, I offer some reflections on the permissibility and advisability of MMTs and what these considerations suggest for the future. (shrink)

In this paper I address some shortcomings in Larry Laudan's normative naturalism. I make it clear that Laudan's rejection of the "meta-methodology thesis", or MMT is unnecessary, and that a reformulated version MMT can be sustained. I contend that a major difficulty that attends Laudan's account is his contention that a naturalistic philosophy of science cannot accommodate any a priori justification of methodological rules, and consider what sort of naturalism might best replace Laudan's. To do this, I discuss Michael Friedman's (...) account of a relativised a priori and show that it is consistent with naturalistic philosophy of science and that it can help form the basis of a plausible normative naturalism. In particular, this Discussion shows that Laudan's rejection of any a priori justification of methodological rules is unjustified and inconsistent with scientific practice. Finally, I point the way to a version of normative naturalism that includes MMT and accounts for the role of constitutive a priori principles within science. (shrink)

Memory modification technologies (MMTs)—interventions within the memory affecting its functions and contents in specific ways—raise great therapeutic hopes but also great fears. Ethicists have expressed concerns that developing and using MMTs may endanger the very fabric of who we are—our personal identity. This threat has been mainly considered in relation to two interrelated concerns: truthfulness and narrative self‐constitution. In this article, we propose that although this perspective brings up important matters concerning the potential aftermaths of MMT utilization, it fails to (...) tell the whole story. We suggest that capturing more tangible potential consequences of MMT use, namely, its psychological ramifications is crucial both in ethical considerations and in making decisions regarding the permissibility of such interventions. To this end, we first examine what current MMTs are capable of and what are the prospects of emerging MMTs. Subsequently, we outline the relationship between memory and personal identity; specifically, we indicate that concepts of self‐defining memories and narrative identity are crucial to considering how MMTs may influence one's psychological functioning. On this basis, we analyze potential consequences of narrative disruption that may be the result of the use of MMTs; more precisely, we consider its potential effects on mental health, well‐being, and personal agency, and outline the ethical dilemmas that decision‐makers face in this context. We conclude by considering the broader cultural context that may have influence on policymaking regarding permissibility of memory modification interventions. (shrink)

The potential of memory modification techniques (MMTs) has raised concerns and sparked a debate in neuroethics, particularly in the context of identity and authenticity. This paper addresses the question whether and how MMTs influence authenticity. I proceed by drawing two distinctions within the received views on authenticity. From this, I conclude that an analysis of MMTs based on a dual-basis, process view of authenticity is warranted, which implies that the influence of MMTs on authenticity crucially depends on the specifics of (...) how memory modification would eventually work. Therefore, I continue with a systematic analysis of possible properties of MMTs in which I distinguish between the dimensions of memories and the kinds of experiences that can be modified as well as the properties of the process of memory modification. The impact of MMTs on authenticity is analyzed regarding the possible properties of MMTs and based on a narrative approach to authenticity which fulfills the requirements of a dual-basis, process view of authenticity. Lastly, I explore the potential of MMTs to shift the balance between self-discovery and self-creation within authenticity and thereby alter the concept itself as well as the value of authenticity.

Methadone maintenance treatment (MMT) is a harm reduction approach for persons who wish to stop using opioids and is rather effective if used for a minimum of 12 months. Notably, research demonstrates that many persons enrolled in MMT programs discontinue care before this time, limiting its effects. To better understand this process, we undertook an exploratory descriptive qualitative study and interviewed 12 men and women who were using MMT. Using the theoretical work of Foucault and Hardt and Negri, the interview (...) data highlighted that MMT continues to be strongly stigmatized, and that it is a system of care that involves rewards and penalties, based on if patients behave according to prescribed norms. These results suggest that MMT is a disciplinary mechanism, albeit one that impedes its own access. We consequently recommend that healthcare providers work to facilitate access to MMT, which means altering care delivery. (shrink)

One objection to enhancement technologies is that they might lead us to live inauthentic lives. Memory modification technologies (MMTs) raise this worry in a particularly acute manner. In this paper I describe four scenarios where the use of MMTs might be said to lead to an inauthentic life. I then undertake to justify that judgment. I review the main existing accounts of authenticity, and present my own version of what I call a “true self” account (intended as a complement, rather (...) than a substitute, to existing accounts). I briefly describe current and prospective MMTs, distinguishing between memory enhancement and memory editing . Moving then to an assessment of the initial scenarios in the light of the accounts previously described, I argue that memory enhancement does not, by its very nature, raise serious concerns about authenticity. The main threat to authenticity posed by MMTs comes, I suggest, from memory editing. Rejecting as inadequate the worries about identity raised by the President’s Council on Bioethics in Beyond Therapy , I argue instead that memory editing can cause us to live an inauthentic life in two main ways: first, by threatening its truthfulness, and secondly, by interfering with our disposition to respond in certain ways to some past events, when we have reasons to respond in such ways. This consideration allows us to justify the charge of inauthenticity in cases where existing accounts fail. It also gives us a significant moral reason not to use MMTs in ways that would lead to such an outcome. (shrink)

Khemlani et al. (2018) mischaracterize logic in the course of seeking to show that mental model theory (MMT) can accommodate a form of inference (, let us label it) they find in a high percentage of their subjects. We reveal their mischaracterization and, in so doing, lay a landscape for future modeling by cognitive scientists who may wonder whether human reasoning is consistent with, or perhaps even capturable by, reasoning in a logic or family thereof. Along the way, we note (...) that the properties touted by Khemlani et al. as innovative aspects of MMT‐based modeling (e.g., nonmonotonicity) have for decades been, in logic, acknowledged and rigorously specified by families of (implemented) logics. Khemlani et al. (2018) further declare that is “invalid in any modal logic.” We demonstrate this to be false by our introduction (Appendix A) of a new propositional modal logic (within a family of such logics) in which is provably valid, and by the implementation of this logic. A second appendix, B, partially answers the two‐part question, “What is a formal logic, and what is it for one to capture empirical phenomena?”. (shrink)

Discussion of the ethics of memory modification technologies has often focused on questions about the limits of their permissibility. In the current paper, I focus primarily on a different issue: when is it rational to prefer MMTs to alternative interventions? My conclusion is that these conditions are rare. The reason stems from considerations of autonomy. When compared with other interventions, MMTs do a particularly poor job at promoting the autonomy of their users. If this conclusion is true, moreover, it provides (...) a fresh perspective on debates about the permissibility of MMTs. On the one hand, for those who would limit the use of MMTs to a narrow range of circumstances, the conclusion that MMTs are rarely preferable gives them further reason to eye MMTs with suspicion. On the other hand, for those who view MMTs as permissible in a wide range of circumstances, the conclusion may deflate their endorsement. (shrink)

The United States health care industry is the second largest in the world, expending an estimated 479 million metric tons (MMT) of carbon dioxide per year, nearly 8 percent of the country's total emissions. The importance of carbon reduction in health care is slowly being accepted. However, efforts to “green” health care are incomplete since they generally focus on buildings and structures. Yet hospital care and clinical service sectors contribute the most carbon dioxide within the U.S. health care industry, with (...) structures/equipment and pharmaceuticals ranking as the third and fourth highest emitters in the industry. Given the magnitude of health care carbon emissions—and the paucity of attention to the carbon of hospital care and clinical services—this essay identifies overuse of health care as a health threat with serious ethical implications, offers a data‐driven action plan for carbon reduction in health care, and provides practical suggestions for more sustainable health care delivery in the United States.

“Functional finance” is an economic theory within the Post Keynesian school of thought. Especially in the form of Modern Monetary Theory (MMT), it has begun to have two big but opposite effects on the debate over Universal Basic Income (UBI). Some people state MMT in an exaggerated way that implies the government can spend all it wants on UBI or anything else without ever raising taxes or borrowing money as if government spending had no limits of any kind. Other people (...) refer to MMT while arguing that any effort to maintain a livable level of UBI is unsustainable. This article discusses the functional finance implications for the cost and sustainability of UBI, arguing that neither of those exaggerated implications are correct. MMT doesn’t free us for the concern for how to support UBI with taxes, but neither does it give reason to believe UBI is any less sustainable. (shrink)

ABSTRACT Advocates of Bitcoin and Modern Monetary Theory present their ideas as radical utopian alternatives to the neoliberal dominant, but these claims neglect the utopian strain in neoliberal monetary theory itself. This strain manifests in that theory’s faith in the capacity of markets to perfect human society. Bitcoin and Modern Monetary Theory express this same faith. After a brief survey of the older, more radical money utopias of More and Proudhon, this article traces the origins of Bitcoin and MMT in (...) the more conventional monetary theories of metallism and chartalism and then analyzes the utopian discourse of both movements, revealing that Bitcoin sees state intervention as the only obstacle to properly functioning markets, while MMT blames disfunction on an inadequate mobilization of labor, proposing state intervention as the remedy. In both cases, their policies only seek to enable the utopian potential of the market, falling in line with neoliberal orthodoxy. The conclusion offers some speculation about what the emergence of these two theories might tell us about the future of neoliberalism. (shrink)

Researchers currently working on relational reasoning typically argue that mental model theory (MMT) is a better account than the inference rule approach (IRA). They predict and observe that determinate (or one-model) problems are easier than indeterminate (or two-model) problems, whereas according to them, IRA should lead to the opposite prediction. However, the predictions attributed to IRA are based on a mistaken argument. The IRA is generally presented in such a way that inference rules only deal with determinate relations and not (...) with indeterminate ones. However, (a) there is no reason to presuppose that a rule-based procedure could not deal with indeterminate relations, and (b) applying a rule-based procedure to indeterminate relations should result in greater difficulty. Hence, none of the recent articles devoted to relational reasoning currently presents a conclusive case for discarding IRA by using the well-known determinate vs indeterminate problems comparison.

Knauff and Gazzo Castañeda (2022) object to using the term “new paradigm” to describe recent developments in the psychology of reasoning. This paper concedes that the Kuhnian term “paradigm” may be queried. What cannot is that the work subsumed under this heading is part of a new, progressive movement that spans the brain and cognitive sciences: Bayesian cognitive science. Sampling algorithms and Bayes nets used to explain biases in JDM can implement the Bayesian new paradigm approach belying any advantages of (...) mental models theory (MMT) at the algorithmic level. Moreover, this paper argues that new versions of MMT lack a computational level theory and questions the grounds for MMTs much-vaunted generality. The paper then examines common ground on the importance of small-scale models/simulations of the world and the importance of argumentation in the social domain rather than individual reasoning. Finally, the paper concludes that although there may be prospects for moving reasoning research forward in a more collective, collaborative manner, many disagreements remain to be resolved. (shrink)

MKM has been defined as the quest for technologies to manage mathematical knowledge. MKM “in the small” is well-studied, so the real problem is to scale up to large, highly interconnected corpora: “MKM in the large”. We contend that advances in two areas are needed to reach this goal. We need representation languages that support incremental processing of all primitive MKM operations, and we need software architectures and implementations that implement these operations scalably on large knowledge bases. We present instances (...) of both in this paper: the MMT framework for modular theory-graphs that integrates meta-logical foundations, which forms the base of the next OMDOC version; and TNTBase, a versioned storage system for XML- based document formats. TNTBase becomes an MMT database by instantiating it with special MKM operations for MMT. (shrink)

Macroeconomic traditions disagree on the policies needed for the economy to properly function and how to assess them. In this paper, we contend that these disagreements originate from the social ontological commitments of a theory. The ontology of money underlines these disagreements between Modern Monetary Theory (MMT) and mainstream economics. First, we assess MMT’s ontology of money. Next, we identify MMT’s normative commitments and classify MMT’s ontology as a taxonomic definition with thick concepts. Finally, we offer reasons why MMT's ontology (...) of money leads to rivalries with other economic traditions. We argue disagreements on policy are expected, given the ontological differences elaborated. (shrink)

Heroin use poses a significant health and economic burden to society, and individuals with heroin dependence are responsible for a significant amount of crime. Owing to its efficacy and cost-effectiveness, methadone maintenance therapy (MMT) is offered as an optional alternative to imprisonment for drug offenders in several jurisdictions. Some object to such 'MMT offers' on the basis that they involve coercion and thus invalidate the offender's consent to MMT. While we find these arguments unpersuasive, we do not attempt to build (...) a case against them here. Instead, we explore whether administration of MMT following acceptance of an MMT offer might be permissible even on the assumption that MMT offers are coercive, and in such a way that the resulting MMT is non-consensual. We argue that non-consensual MMT following an MMT offer is typically permissible. We first offer empirical evidence to demonstrate the substantial benefits to the offender and society of implementing non-consensual MMT in the criminal justice system. We then explore and respond to potential objections to such uses of MMT. These appeal respectively to harm, autonomy, bodily and mental interference, and penal theoretic considerations. Finally, we introduce and dismiss a potential response to our argument that takes a revisionist position, rejecting prevailing incarceration practices. (shrink)

Modern Monetary Theory and Distributive Justice shows how the macroeconomic framework called modern money theory (MMT) is relevant to the field of political philosophy called distributive justice. Many of the macroeconomic assumptions of distributive justice are unstated and unexamined. The framework of MMT illuminates these assumptions and provides an alternative vision of distributive justice analysis and prescriptions. In particular, MMT holds that modern money is a nominal state issued token (fiat), there is a distinction between nominal assets and real assets, (...) that state money as a nominal token can cause changes in real terms, and that the macroeconomy has historically not operated at capacity. The upshot of these assumptions held by MMT is that state spending can bring about changes in persons’ well-being without traditional redistributive measures via taxation. This is in contradistinction to standard assumptions in the distributive justice literature, which holds that the macroeconomy is at capacity and, thus, redistribution is the necessary mechanism for enacting improvements in well-being. This is a fundamental shift in how distributive justice can be conceived. (shrink)

This paper uses the case-study of controversy over the MMT vaccine to suggest that non-expert audiences might have a fairness-based "political" obligation to defer to expert scientific consensus. The first part of the paper notes various reasons why it is implausible to argue that non-experts are epistemically obliged to defer to the consensus. The second draws on the literature on vaccination ethics more generally to argue for the alternative political obligation to defer. The third section considers some objections, and the (...) conclusion discusses how recognising such an obligation might alter contemporary debates. (shrink)

Social information processing theory suggests that the chief executive officer’s entrepreneurial orientation is an organisational signal that influences the members’ innovativeness. Middle management teams are expected to be more innovative as they connect senior managers with frontline managers in the dynamic competitive environment of the digital economy. How CEOs guide MMT innovations through EO becomes critical in the process of capturing opportunities and creating value. However, previous research has failed to adequately identify distinct CEO EO manifestations with organisational contexts configurations (...) that influence MMTs innovation. Thus, based on differences in organisational contexts and MMTs’ cognition, this study thoroughly investigates how the vertical manifestation of CEO EO impacts the innovativeness of MMTs. We used fuzzy-set qualitative comparative analysis on a sample of 117 organisations to determine which configurations of CEO EO vertical penetration within an organisation can stimulate MMT innovativeness. The study discovered four first-level configurations that support stimulating MMT innovativeness respectively when the CEO EO is fully or partially manifested, and without the CEO EO. Moreover, we found the internal reasons for MMTs’ information interpretation heterogeneity, which is critical for realising the coordination and unity of entrepreneurial cognition and behaviours. Finally, these findings’ theoretical and practical implications are discussed. (shrink)

Selective mutism (SM) is a developmental disorder characterized by a child’s inability to speak in certain contexts and/or in the presence of unfamiliar interlocutors. This work proposes a critical discussion of the most recent studies on SM, with respect to clinical and diagnostic features, as well as the etiology and treatment of this disorder. At present, all research work supports the hypothesis that SM is a complex anxiety disorder with multifactorial etiology (interaction among biological and environmental causes). The latest edition (...) of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013) places SM mutism among “Anxiety Disorders”, and no longer among “Other Childhood, Infant and Adolescent Disorders” (as in DSM-IV). Other important aspects relate to cognitive biases and emotional states at the base of SM, which partly explain the disorder’s persistence and represent an important objective of intervention work. No data in the literature point to a total remission of SM, but good results are achieved with cognitive behavior intervention and multimodal therapy (MMT) involving a variety of child interaction contexts.

BackgroundRecent advancements in neuroscientific techniques have allowed us to make huge progress in our understanding of memories, and in turn has paved the way for new memory modification technologies that can modulate memories with a degree of precision, which was not previously possible. With advancements in such techniques, new and critical ethical questions have emerged. Understanding and framing these ethical questions within the current philosophical theories is crucial in order to systematically examine them as we translate these techniques to the (...) clinic.Main bodyIn this paper, we discuss the ethical implications of modern neuroscience techniques that aim to disrupt or enhance memories. We attempt to frame the MMTs in the context of existing ethical philosophical theories to provide a cohesive analysis of the myriad of ethical quagmires that might emerge from such technologies. We argue the application of Aristotle’s Golden Mean and multiple accounts of authenticity are useful in approaching the ethical questions surrounding MMTs. We then propose a framework in which ethical considerations can be systematically examined. Lastly, we provide caveats and considerations for the use of this framework. Overall, we provide a practical approach for the ethical use of MMTs depending on the situation.ConclusionWhile at face value, our model appears to put severe limitations on the application of MMTs, we are not completely opposed to their use, but rather our framework guides the agent to consider the implications before making any decisions. Most importantly, we argue that the use of MMTs does not reduce the responsibility of the initial decision, and the agent must accept the post-MMT self as the new “true self” regardless of the outcome. As the developmental trajectory of MMTs suggests we are getting closer to practical clinical applications, ethical concerns across a wide range of disciplines need to be addressed to develop best strategies and policies when dealing with MMTs. If this can be achieved, we believe the ethical use of MMTs is not only possible but would also be of tremendous benefit to many people suffering from memory-related mental disorders. (shrink)

Background: The present article aims to measure the extent to which the physical and recreational needs of elderly persons in the communities of Posorja and Puna are being met. Nowadays, it is known that physical activity is beneficial for the elderly, as it helps to diminish illness and all kinds of diseases. Method: The population in this study is comprised on 378 elderly persons between 65 and 79 years of age: 200 belong to the community of Posorja and 178, to (...) the community of Puna in Guayas Province. The tools used for this research include, among others, the ADL Test, which evaluates the degree of self-care and mobility; the Lawton and Brody Scale, which is an appropriate instrument to evaluate the level of independence and skills; and the MMT, which evaluates cognitive functions such as memory, language, praxis and attention. They all are essential to detecting and diagnosing Alzheimer´s disease. Results: Various statistical techniques were used to obtain the results, such as descriptive analysis, contingency tables and main components. Conclusions: The population between 65 and 90 years of age was analyzed and it accounted for 35.9% of the total population back in 2010, which means there was a variation. Nowadays, it represents 56.6% of the obtained sample. This generational group refers to the elderly, who should be favored by public policies that are intended to improve health programs, generate recreational areas, and create senior care centers. Generally, the demographic dynamics of Posorja show a structured pyramid, with an expanding population, a large amount of young people and adults who contribute to the economic dynamics and productivity of the area. The questionnaire could be adapted and contain the specifications required to suit the true dimensions of this population. (shrink)

In the most recent Teaching and Learning International Survey (TALIS2018) conducted by the Organisation for Economic Cooperation and Development (OECD), the percentage of Japanese teachers who taught critical thinking (CT) and professed self-efficacy in CT teaching was by far the lowest among participating economies (OECD, 2019). This research explores the emic or indigenous understanding of CT in Japanese education through in-depth qualitative interviews with 12 schoolteachers of diverse backgrounds. Japanese schoolteachers find the nuance of CT undesirable. Yet, a particular facet (...) of CT, namely multidimensional-multiperspective thinking (MMT), is well-received since the national curriculum guidelines, which most participants find to be their teaching foundation, lay strong emphasis on MMT. Almost all participants agree that low socioeconomic-status (SES) schools have difficulty teaching CT/MMT. Furthermore, a hidden curriculum in Japanese schools, namely valuing empathy, also affects CT teaching. Being empathetic constitutes a core value in Japanese schooling, so participants find it impossible to practice CT without teaching empathy. The findings suggest that the curricular power, whether official or implicit, is forceful in Japan. Still, schoolteachers practise indigenous versions of CT teaching and manage to keep away from the power of the etic/global model of CT teaching. This paper concludes with practical implications for educators to reconcile the etic and emic understandings of CT teaching. (shrink)

PurposeThe aim of this study was to investigate and compare impulsiveness, negative emotion, cognitive function, and P300 components among gamma-hydroxybutyrate -addicted patients, heroin-dependent patients, and methadone maintenance treatment subjects.MethodsA total of 48 men including 17 GHB addicts, 16 heroin addicts, 15 MMT subjects, and 15 male mentally healthy controls were recruited. All subjects were evaluated for symptoms of depression, anxiety, impulsiveness, and cognitive function through the Patient Health Questionnaire, the Generalized Anxiety Disorder 7-item, the Barratt Impulsiveness Scale version II, the (...) Beijing version of the Montreal Cognitive Assessment, the behavioral test, and event-related potential P300 detection.Results The mean scores of BIS-II in the GHB addiction group, heroin dependence group, and MMT group were significantly higher than those of the HC group. The total scores of BJ-MOCA in GHB addiction group was the worst among the four groups, followed by heroin addiction, MMT group and HC group. The response time in the GHB addiction group was the longest among the four groups, followed by the heroin addiction, MMT, and HC groups. The amplitude and latency of P300 in GHB addiction subjects were significantly lower and longer than those of the MMT group and the HC group. For the three types of addiction, the P300 amplitudes at Fz, Cz, Pz, T5, and T6 were negatively correlated with the scores of GAD-7, PHQ-9, and BIS-II; the P300 latencies were positively correlated with the response time and negatively correlated with the scores of the BJ-MoCA.ConclusionPeople with an addiction were likely to have increased impulsiveness. The cognitive function of the GHB and heroin-addicted subjects, including the heroin detoxification and the MMT groups, was severely impaired, especially for the GHB-addicted patients. The impairment manifested as abnormalities of BJ-MoCA, response time, and P300 components. (shrink)
