This paper considers psychotic symptoms in terms of false inferences or beliefs. It is based on the notion that the brain is an organ of inference that actively constructs hypotheses to explain or predict its sensations. This perspective provides a normative account of action and perception that emphasises probabilistic representations; in particular, the confidence or precision of beliefs about the world. We consider sensory attenuation deficits, catatonia and delusions as various expressions of the same core pathology: namely, an aberrant encoding (...) of precision in a predictive coding hierarchy. In predictive coding, precision is thought to be encoded by the postsynaptic gain of neurons reporting prediction error. This suggests that both pervasive trait abnormalities and florid failures of inference in the psychotic state can be linked to factors controlling postsynaptic gain—such as NMDA receptor function and neuromodulation. We illustrate these points using a biologically plausible simulation of attribution of agency—showing how a reduction in the precision of prior beliefs, relative to sensory evidence, can lead to false inference.

This Editorial introduces the thematic series on 'Toward a New Psychiatry: Philosophical and Ethical Issues in Classification, Diagnosis and Care' http://www.biomedcentral.com/series/newpsychiatry.

Many psychiatrists tell their clients that any mental disorder is ‘‘a disease, just like diabetes’’. This slogan appears to suggest that mental states and behavior that are classified ‘‘mental disorders’’ are somehow radically different from other mental states and behaviors—both when it comes to simply understanding people and when it comes to moral assessments of mental states and of actions. After all, mental illness is just like diabetes, while other human conditions are not. That sounds like a huge difference. I (...) think this suggestion is misleading. (shrink)

This essay concerns a philosophical examination of the nature of mind and the relevant implications for mental health. Traditionally, realism and constructivism are regarded as two contrastive positions in explaining the nature of mind. While realists take discovery of reality as the main function of mind, constructivists regard it as creation of reality. Hence, epistemologically, realists emphasize on correspondence to reality as the criterion of validity or truth of the mind's contents, whereas constructivists regard the inner coherence of constructs as (...) the main criterion. inner coherence of constructs or resolving inner conflicts; capability of constructs for adaption to problematic situations; and correspondence to reality as an ideal in the long run are the discussions and aims of this paper.

Patients with behavioral variant of frontotemporal dementia (FTD) have difficulties recognizing facial emotions, a deficit that may contribute to their impaired social skills. In three experiments, we investigated the FTD deficit in recognition of facial emotions, by comparing six patients with impaired social conduct, nine Alzheimer’s patients, and 10 age-matched healthy adults. Experiment 1 revealed that FTD patients were impaired in the recognition of negative facial emotions. Experiment 2 replicated these findings when participants had to determine whether two faces were (...) expressing the same or different emotions. Experiment 3 was a control study in which participants had to discriminate whether two faces were of the same sex. In this non-emotional processing task, both patient groups performed worse than normal participants, but FTD patients performed as well as Alzheimer’s patients. We conclude that FTD patients are impaired in the recognition of negative facial emotions. © 2005 Elsevier Ltd. All rights reserved. (shrink)

Progress in psychiatry depends on accurate definitions of disorders. As long as there are no known biologic markers available that are highly specific for a particular psychiatric disorder, clinical practice as well as scientific research is forced to appeal to clinical symptoms. Currently, the nosology of obsessive-compulsive disorder is being reconsidered in view of the publication of DSM-V. Since our diagnostic entities are often simplifications of the complicated clinical profile of patients, definitions of psychiatric disorders are imprecise and always indeterminate. (...) This urges researchers and clinicians to constantly think and rethink well-established definitions that in psychiatry are at risk of being fossilised. In this paper, we offer an alternative view to the current definition of obsessive-compulsive disorder from a phenomenological perspective.TranslationThis article is translated from Dutch, originally published in [Handbook Obsessive-compulsive disorders, Damiaan Denys, Femke de Geus (Eds.), (2007).

Self-reflection plays a key role in healthy human adaptation. Self-reflection might involve different capacities which may be impaired to different degrees relatively independently of one another. Variation in abilities for different forms of self-reflection are commonly seen as key aspects of many adult mental disorders. Yet little has been written about whether there are different kinds of deficits in self-reflection found in mental illness, how those deficits should be distinguished from one another and how to characterize the extent to which (...) they are interrelated. We review clinical and experimental literature and suggest four different forms of deficits in self-reflection: sense of ownership of one’s own thoughts and actions, emotional awareness, distinction between fantasy and reality and the integration of a range of different views of oneself and others. We propose how these different impairments in self-reflection are linked with one another. (shrink)

Background and Objective: Understanding how trauma impacts the self-structure of individuals suffering from the Post-Traumatic Stress Disorder (PTSD) symptoms is a complex matter and despite several attempts to explain the relationship between trauma and the “Self”, this issue still lacks clarity. Therefore, adopting a new theoretical perspective may help understand PTSD deeper and to shed light on the underlying psychophysiological mechanisms. Methods: In this study, we employed the “three-dimensional construct model of the experiential selfhood” where three major components of selfhood (...) (phenomenal first-person agency, embodiment, and reflection/narration) are related to three Operational Modules (OMs) of the self-referential brain network. These modules can be reliably estimated through operational synchrony analysis of the Electroencephalogram (EEG). Six individuals with PTSD symptoms and twenty-nine sex-, age- and demographic- (race, education, marital status) matched healthy controls underwent resting state EEG signal acquisition with the following estimation of the synchrony strength within every OM. Results: Our results indicate that subjects with PTSD symptoms had significantly stronger EEG operational synchrony within anterior and right posterior OMs as well as significantly weaker EEG operational synchrony within left posterior OM compared to healthy controls. Moreover, increased the functional integrity of the anterior OM was positively associated with hyperactivity symptoms, reduced synchrony of the left posterior OM was associated with greater avoidance, and increased right posterior OM integrity was positively correlated with intrusion and mood symptoms. Conclusion: The results are interpreted in light of the triad model of selfhood and its theoretical and clinical implications (including a new treatment approach) are discussed. (shrink)

Concepts We thank all three commentators for extremely constructive, insightful, and gracious commentaries. We cannot address all their valuable points. In this response, we elucidate and relate the concepts of addiction, disease, disability, autonomy, and well-being. We examine some of the implications of these relationships in the context of the helpful responses made by our commentators. We begin with the definitions of the relevant concepts which we employ: ¥? ? ? Addiction (Liberal Concept): An addiction is a strong appetite. ¥? (...) ? ? Appetites: An appetite is a disposition that generates desires that are urgent, oriented toward some rewarding behavior, periodically recurring, often in predictable circumstances, sated temporarily by their fulfillment, and generally provide pleasure. ¥? ? ? Disease (Naturalistic Concept): A disease is some biological or psychological state that results in subfunctioning of the organism in a given set of environmental and social circumstances, C. The reference class is a natural class of organisms of uniform functional design; specifically, an age group of a sex of a species. A normal function is a part or process within members of the reference class and is a statistically typical contribution by it to their individual survival and reproduction (Boorse 1977, 1997). ¥? ? ? Disability (Welfarist Concept): A disability is a relatively stable biological or psychological state that tends to reduce the amount of well-being that this person will enjoy in a given set of environmental and social circumstances (Savulescu and Kahane 2009; Kahane and Savulescu, 2009). ¥? ? ? Autonomy (Rationalist Concept): A person rationally desires or values some state of affairs if and only if he or she desires that state of affairs while (1) being in possession of all relevant.

Philosophers and psychologists have been attracted to two differing accounts of addictive motivation. In this paper, we investigate these two accounts and challenge their mutual claim that addictions compromise a person’s self-control. First, we identify some incompatibilities between this claim of reduced self-control and the available evidence from various disciplines. A critical assessment of the evidence weakens the empirical argument for reduced autonomy. Second, we identify sources of unwarranted normative bias in the popular theories of addiction that introduce systematic errors (...) in interpreting the evidence. By eliminating these errors, we are able to generate a minimal, but correct account, of addiction that presumes addicts to be autonomous in their addictive behavior, absent further evidence to the contrary. Finally, we explore some of the implications of this minimal, correct view. (shrink)

Understood in their historical context, current debates about psychiatric classification, prompted by the publication of the DSM-5, open up new opportunities for improved translational research in psychiatry. In this paper, we draw lessons for translational research from three time slices of 20th century psychiatry. From the first time slice, 1913 and the publication of Jaspers’ General Psychopathology, the lesson is that translational research in psychiatry requires a pluralistic approach encompassing equally the sciences of mind (including the social sciences) and of (...) brain. From the second time slice, 1953 and a conference in New York from which our present symptom-based classifications are derived, the lesson is that, while reliability remains the basis of psychiatry as an observational science, validity too is essential to effective translation. From the third time slice, 1997 and a conference on psychiatric classification in Dallas that brought together patients and carers with researchers and clinicians, the lesson is that we need to build further on collaborative models of research combining expertise-by-training with expertise-by-experience. This is important if we are to meet the specific challenges to translation presented by the complexity of the concept of mental disorder, particularly as reflected in the diversity of desired treatment outcomes. Taken together, these three lessons – a pluralistic approach, reliability and validity, and closer collaboration – provide an emerging framework for more effective translation of research into practice in 21st century psychiatry.

This chapter identifies and explores a series of challenges raised by the clinical concept of delusion for theories which conceive autonomy as an agency rather than a status concept. The first challenge is to address the autonomy-impairing nature of delusions consistently with their role as grounds for full legal and ethical excuse, on the one hand, and psychopathological significance as key symptoms of psychoses, on the other. The second challenge is to take into account the full logical range of delusions, (...) which may take the form of true or false factual beliefs, positive or negative evaluations, as well as the paradoxical delusion of mental illness. The third and final challenge is to make room for non-pathological or, autonomy-preserving delusions and to offer a credible way of distinguishing between these and pathological or, autonomy-impairing delusions. By setting out these challenges, we are able to, firstly, distinguish between two separate conceptions of objectivity that may be at work in existing accounts of delusions and, secondly, to put a spotlight on an elusive yet inescapable notion of agential success that underlies our thinking about autonomy as well as mental disorder.

This is a reply to Gipps' commentary on my 'The Concept of Mental Disorder'.

During the last years, there has been an important discussion on the concept of mental disorder. Several accounts of such a concept have been offered by theorists, although neither of these accounts seems to have successfully answered both the question of what it means for a certain mental condition to be a disorder and the question of what it means for a certain disorder to be mental. In this paper, I propose an account of the concept of mental disorder that, (...) if I am right, provides satisfactory answers to both of these questions. Furthermore, this account (unlike other accounts presented in the literature on the subject) meets the requirements for achieving a crucial goal underlying the project of sorting out the concept of mental disorder, namely the goal of allowing the existence of a dialogue between mental health professionals of different theoretical orientations. To achieve this goal, the account herein proposed is not based in any particular theoretical framework, but in both ordinary and technical theory-neutral concepts. In the last part of the paper, I argue that it follows from most accounts of the concept of mental disorder that the disciplines concerned with explaining some mental disorders are not branches of medicine, and that the treatment of some mental disorders is not a matter of medical intervention.

A large part of the debate around the right to refuse life-prolonging treatment of anorexia nervosa sufferers centers on the issue of competence. Whether or not the anorexic should be allowed to refuse life-saving treatment does not depend solely or primarily on competence. It also depends on whether the anorexic’s suffering is bearable or tractable, and on the degree of involvement of the family in the therapeutic process. Anorexics could be competent to refuse lifesaving treatment (Giordano 2008). However, the anorexic’s (...) refusal of life-saving treatment should not be respected purely because it is a competent decision. In fact, anorexia has two characteristics that weaken the strength of the principle .. (shrink)

According to human enhancement advocates, it is morally permissible (and sometimes obligatory) to use biomedical means to modulate or select certain biological traits in order to increase people’s welfare, even when there is no pathology to be treated or prevented. Some authors have recently proposed to extend the use of biomedical means to modulate lust, attraction, and attachment. I focus on some conceptual implications of this proposal, particularly with regard to bioconservatives’ understanding of the notions of therapy and enhancement I (...) first explain what makes the proposal of medicalizing love interesting and unique, compared to the other forms of bioenhancement usually advocated. I then discuss how the medicalization of love bears on the more general debate on human enhancement, particularly with regard to the key notion of “normality” that is commonly used to define the therapy–enhancement distinction. This analysis suggests that the medicalization of love, in virtue of its peculiarity, requires bioconservatives to reconsider their way of understanding and applying the notions of “therapy” and “enhancement.” More in particular, I show that, because a non-arbitrary and value-free notion of “therapy” cannot be applied to the case of love, bioconservatives have the burden of either providing some new criterion that could be used for drawing a line between permissible and impermissible medicalization, or demonstrating that under no circumstances—including the cases in which love is already acknowledged to require medical intervention—can love fall within the domain of medicine.

Behrendt & Young's (B&Y's) novel “unifying model” of hallucinations, although comprehensive, fails to incorporate research into the possible role of 5-HT2A receptors in the mode of action of novel “atypical” antipsychotic drugs (which treat hallucinations effectively), and into the role of such receptors, which are located in thalamocortical circuits, in mediating drug-induced hallucinations.

The aim of the article is to present the contemporary concepts of delusions from the phenomenological perspective. The difficulties to define delusions and the examples of delusional disorders, such as delusional mood, Cotard’s syndrome, or Capgras delusions, serve as the point of departure for this analysis. The questions of the phenomenological understanding of delusions are presented in the context of Karl Jaspers' theory of the incomprehensibility of psychotic thinking (primary delusions, delusional mood). The subsequent analysis presents the constraints of contemporary (...) cognitive theories of delusions. The criticism of said theories highlights the need for creating a broader concept of experience and cognition and results in the proposition to use the terms "background" and “embodiment" as theoretical tools for a more complete understanding of the peculiarities of delusional experience.

In psychiatry there is no sharp boundary between the normal and the pathological. Although clear cases abound, it is often indeterminate whether a particular condition does or does not qualify as a mental disorder. For example, definitions of ‘subthreshold disorders’ and of the ‘prodromal stages’ of diseases are notoriously contentious. -/- Philosophers and linguists call concepts that lack sharp boundaries, and thus admit of borderline cases, ‘vague’. Although blurred boundaries between the normal and the pathological are a recurrent theme in (...) many publications concerned with the classification of mental disorders, systematic approaches that take into account philosophical reflections on vagueness are rare. This book provides interdisciplinary discussions about vagueness in psychiatry by bringing together scholars from psychiatry, psychology, philosophy, history, and law. It draws together various lines of inquiry into the nature of gradations between mental health and disease and discusses the individual and societal consequences of dealing with blurred boundaries in medical practice, forensic psychiatry, and beyond. -/- Part I starts with an overview chapter that helps readers to navigate through the philosophy of vagueness and through the various debates surrounding demarcation problems in the classification and diagnosis of mental illness. Part II encompasses historical and recent philosophical positions on gradualist approaches to health and disease. Part III approaches the vagueness of present psychiatric classification systems, and the debates concerning their revisions by scrutinizing controversial categories, such as posttraumatic stress disorder, and the difficulties of day-to-day diagnostic and therapeutic practice. Part IV finally focuses on social, moral, and legal implications that arise when being mentally ill is a matter of degree. (shrink)

Substance use and misuse occurs at a very high rate among people with mental health problems and the relationship between the two conditions is complex. In this paper we argue that treatment of substance use in dual diagnosis clients must begin from an understanding of the losses suffered by those with mental illness. We outline the fundamental condition of effective agency, unified agency, which is disrupted in mental illness and show how this is needed to secure access to central social (...) and moral goods such as continuing employment and satisfying relationships. We argue that drug use will be disvaluable primarily in so far as it too prevents access to this set of agential goods and focuses the agent on synchronic well-being to the exclusion of diachronic well-being. The goals and methods of treatment for dual diagnosis patients should thus reflect the primary impairment to unified agency. (shrink)

Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

In their 2013 study of traumatic flashback formation, Bourne, Mackay and Holmes raise the question of whether the propensity of a traumatic experience to produce flashbacks is determined by the emotions that are felt at the time of that experience. They suggest that it is not, but the grounds on which they make this suggestion are flawed. Further research is required. That research will need to overcome a significant methodological difficulty — one which is hard to avoid when fMRI data (...) and introspective reports are combined in a single causal inference.

In this Introduction, I situate the underlying project “Autonomy and Mental Disorder” with reference to current debates on autonomy in moral and political philosophy, and the philosophy of action. I then offer an overview of the individual contributions. More specifically, I begin by identifying three points of convergence in the debates at issue, stating that autonomy is: 1) a fundamentally liberal concept; 2) an agency concept and; 3) incompatible with (severe) mental disorder. Next, I explore, in the context of decisional (...) capacity assessments, the difficulties to reconcile 1) and 2) with 3) which they at the same time seem to imply. Having clarified the centrality of a cogent notion of mental disorder for addressing these difficulties, I comment on three promising lines of inquiry about the nature and scope of autonomy that emerge from the following chapters.

The essay aims to analyse the gradual historical process of the partial overlap, replacement and expansion of the theoretical paradigm of depression with respect to that of melancholy. The first part is devoted to analysing some of the central features of the multivalent thematizations of melancholy drawn up during modernity, also with relation to the spirit of capitalism (in its Weberian acceptation). This is followed by an overview of the birth of the modern category of depression, and the process that (...) during the twentieth century led to its transformation into a theoretical and nosological paradigm which in the end replaced that of melancholy. The second part is the attempt to draw up a Zeitdiagnose: the aim is to assess the ‘depressive’ psychosocial impact exercised by particular socio-economic mechanisms and cultural trends, with particular reference to what has been defined as the ‘new spirit of capitalism’, as well as the new forms of individualism and their paradoxical dynamics. In conclusion, I will form a bridge between the history of the two aforesaid paradigms and the contemporary psychosocial dynamics correlated to the phenomenon today interpreted as a ‘depression epidemic’. Der Aufsatz zielt darauf, der Prozess der historischen Überlagerung, Substitution und Verbreitung des theoretischen Paradigmas der Depression gegenüber jenem der Melancholie darzustellen. Im ersten Teil wird versucht, einige der einschneidenden Eigenschaften der Thematisierungen der Melancholie in der Frühen Neuzeit anzugeben, auch im Verhältnis zum Geist des Kapitalismus. Nachdem eine Skizze der Entstehung der moderne Kategorie der Depression, geht es darum, den Verlauf nachzuzeichnen, der im 20. Jahrhundert zu ihrer Transformation in ein weitläufiges theoretisches Paradigma geführt hat, das schließlich jenes der Melancholie ersetzt hat. Der zweite Teil stellt den Versuch dar, eine Zeitdiagnose umzureißen: An dieser Stelle ist die psychosoziale Bedeutung bestimmter sozioökonomischer und kultureller Mechanismen zu untersuchen, unter besonderem Hinweis auf das, was als »der neue Geist des Kapitalismus« bezeichnet worden ist, sowie auf neue Formen des Individualismus und ihre paradoxen Dynamiken. Abschließend wird eine Brücke geschlagen, zwischen der Geschichte der beiden bezeichneten Paradigmen und der zeitgenössischen psychosozialen Dynamiken, die mit dem als »depressive Epidemie« interpretierten Phänomen verbunden sind.

Il saggio mira ad analizzare il graduale processo storico di parziale sovrapposizione, sostituzione ed ampliamento del paradigma teoretico della depressione rispetto a quello della melanconia. La prima parte è dedicata ad analizzare alcuni dei tratti nevralgici delle polivalenti tematizzazioni della malinconia avvenuti nel corso della modernità, anche in relazione allo spirito del capitalismo (nella sua accezione weberiana). Segue una panoramica sulla nascita della categoria moderna di depressione, e del processo che nel corso del XX secolo l’ha condotta alla sua trasformazione in un paradigma teoretico e nosologico che ha infine sostituito quello della melanconia. La seconda parte rappresenta il tentativo di elaborare una Zeitdiagnose: l’obiettivo è valutare l’impatto psicosociale di natura ‘depressiva’ esercitato da particolari meccanismi socioeconomici e tendenze culturali, con particolare riferimento a ciò che è stato definito il «nuovo spirito del capitalismo», nonché alle nuove forme dell’individualismo e alle loro dinamiche paradossali. In conclusione viene gettato un ponte tra la storia dei due suddetti paradigmi e le dinamiche psicosociali contemporanee correlate al fenomeno oggi interpretato quale «epidemia depressiva». (shrink)

Psiche sets up a close-knit comparison between the psychology of Plato's Republic and Freud's psychoanalysis. Convergences and divergences are discussed in relation both to the Platonic conception of the oneiric emergence of repressed desires that prefigures the main path of Freud's subconscious, to the analysis of the psychopathologies related to these theoretical formulations and to the two diagnostic and therapeutic approaches adopted. Another crucial theme is the Platonic eros - the examination of which is also extended to the Symposium and (...) Phaedrus - taken up explicitly by Freud in relation to the concept of libido. Finally, the author also addresses the two themes - of, inter alia, a metapsychological nature - inherent to the moral dimension. -/- Psiche istituisce un confronto ravvicinato tra la psicologia della "Repubblica" di Platone e la psicoanalisi di Freud. Convergenze e divergenze vengono discusse in relazione sia alla concezione platonica dell'emersione onirica dei desideri repressi, che prefigura la via regia per l'inconscio di Freud, sia all'analisi delle psicopatologie correlate a tali impostazioni teoriche, sia ai due approcci diagnostici e terapeutici adottati. Altro tema cruciale è l'eros platonico - la cui disamina viene estesa anche al "Simposio" e al "Fedro" - ripreso esplicitamente da Freud in relazione al concetto di libido. L'autore affronta, infine, le due tematizzazioni, di natura metapsicologica e non solo, inerenti alla dimensione morale. (shrink)

This chapter has two aims. The first aim is to compare and contrast three different conceptual-explanatory models for thinking about mental illness with an eye towards identifying the assumptions upon which each model is based, and exploring the model’s advantages and limitations in clinical contexts. Major Depressive Disorder is used as an example to illustrate these points. The second aim is to address the question of what conceptual-theoretical framework for thinking about mental illness is most likely to facilitate the discovery (...) of causes and treatments of mental illness in research contexts. To this end, the National Institute of Mental Health’s Research Domain Criteria (RDoC) Project is briefly considered. (shrink)

Oulis pointed out that there is a great deal of interest in specific mechanisms relating to mental disorders and that these mechanisms should play a role in classification. Although specific mechanisms are important, more attention should be given to general theories. The following example from Salmon illustrates the difference.

Suicidal ideation would often appear to relate to ideas about life’s meaninglessness. In this chapter, I consider the suicidal thoughts of an elderly person in light of the recent philosophical discussion on the meaning of life. I start by distinguishing between two importantly different questions about life’s meaning and explaining how they differ from certain other issues sometimes treated as questions about the meaning of life. Then I address the two questions about life’s meaning in turn, connecting them to the (...) example case. After that, I briefly consider how the elderly person’s committing suicide would appear from the viewpoint of the philosophical debate on life’s meaning. I conclude by summing up how the philosophical discussion on the meaning of life I have referred to might help a person like the one in the example case. (shrink)

Sorensen raises the issue of whether it is logically possible to fake Munchausen's syndrome by way of a fictional exchange between a physician and an insurance company. In this paper, it is shown that it is possible to fake Munchausen's syndrome and to fake faking Munchausen's syndrome. The implications of this on deeper philosophical issues such as Lewis' puzzle of iterated pretence and “internalist” versus “externalist” accounts of faking are discussed. An externalist account of faking is defended and offered as (...) a solution to Lewis' puzzle as it arises in this context. (shrink)

Recent papers on the Capgras delusion have focused on the role played by subpersonal abductive inference in the formation and maintenance of the delusional belief. In these accounts, the delusional belief is posited as the first delusion-related event of which the patient is conscious. As a consequence, an explanatory role for anomalous patient experience is denied. The aim of this paper is to challenge this revisionist position and to integrate subpersonal inference within a model of the Capgras delusion which includes (...) a role for experiential content. I argue that the following revisionist claims are problematic: (a) that a fully-formed belief enters consciousness, and (b) that this is the first conscious delusion-related event. Instead, it is my contention that a delusional thought (arrived at through subpersonal abductive inference) and an anomalous experience co-occur in consciousness prior to the formation of the delusional belief. The co-occurrence of thought and anomalous experience overcomes problems with the revisionist position resulting in an account of the Capgras delusion with greater explanatory efficacy. (shrink)
