Huttenlocher et al. (J Exp Psychol Gen 129:220–241, 2000) introduce the category adjustment model (CAM). Given that participants imperfectly remember stimuli (which we refer to as “targets”), CAM holds that participants maximize accuracy by using information about the distribution of the targets to improve their judgments. CAM predicts that judgments will be a weighted average of the imperfect memory of the target and the mean of the distribution of targets. Huttenlocher et al. (2000) report on three experiments and conclude that (...) CAM is “verified”. We attempt to replicate the conditions in Experiment 3 from Huttenlocher et al. (2000). We analyze judgment-level data rather than averaged data. We find evidence of a bias toward a set of recent targets rather than a bias toward the running mean. We do not find evidence of learning. The judgments in our dataset are not consistent with CAM. We discuss other defects in HHV—including dividing by zero. It seems that evidence for CAM is a statistical artifact that appears when researchers analyze data averaged across trials and do not consider a recency bias. (shrink)

In Powers of Horror,1 the psychoanalyst Julia Kristeva presented the first explicit, elaborated theory of ‘abjection,’ which she defines as the casting off of that which is not of one’s “clean and proper”2 self. According to Kristeva, abjection is a demarcating impulse which establishes the basis of all object relations, and is operative in the Lacanian narrative of subject formation in early childhood via object differentiation. Abjection continues to operate post-Oedipally to prevent the dissolution of the subject by repressing identification (...) with that which is other, and particularly that which is only tenuously other: the abject. Though Kristeva’s theory is braided into problematic Freudian premises, this essay will argue that abjection remains operative independent of the Oedipal model. (shrink)

In a recent paper in this journal, Dagsvik derives the class of independent random utility representations that are “equivalent” to the independence-from-irrelevant-alternatives assumption by Luce. In this short note, we clarify the relations between this paper by Dagsvik, and a paper in Lindberg’s 2012 thesis.

In lieu of an abstract, here is a brief excerpt of the content:Deception in Psychological ResearchJohn P. Gluck and Stephen Hahn-SmithMadam: In the March 1995 issue of the KIEJ, Sissela Bok adds meaningfully to her consistent and important analysis of the harms associated with deception in biomedical and behavioral research. She reminds us that investigator and review committee domination of the analysis of costs and benefits deprives the prospective research subjects of the opportunity to apply their unique sense of values (...) and preferences, an obligation that flows from an authentic respect for persons and a recognition of the importance of autonomy.She also correctly points out that the American Psychological Association (APA) is unique in that it acknowledges the harms of deception by requiring scientific [End Page 386] justification, limiting the scope of what factors can be part of the deception, and supporting minimal duration of deception, at the same time as it maintains a very permissive stance toward its use. For example, the APA code of conduct requires that alternatives to deception be implemented only when they are deemed to be "equally effective."What Bok omits in her critique is that a common justification for the use of deception by psychologists is the belief that many research subjects actually benefit from being deceived. This impression is based on studies that interview subjects at some point in time after their experimental experience. For example, Smith and Richardson (1983, p. 1080) concluded that: "In general, respondents who have been deceived while participating in psychological research did not report negative effects of their experience. In fact, they perceived their experiences more positively that did respondents who had not participated in studies employing deception." Christensen (1988, p. 668), after reviewing the literature on subject reaction to deception, states that the evidence supports the notion that deception experiments are perceived as "more enjoyable and beneficial than nondeception experiments." He goes on to say that in the face of these data it may be that deception has gotten its bad name from philosophers!Basing the acceptability of deception on direct sampling of subjects' highly personal reactions assumes that the procedure yields responses that are valid on their face. If this is true, it would seem to undermine the typical justification for deception in the first place, which is that subjects when asked for personal information are likely to respond in misleading ways. It is important to note that evidence suggests that if subjects are queried about the acceptability of deception prior to actual participation, substantial proportions of subjects judge deception to be unacceptable (Korn 1987). These results are consistent with our own recently completed research, which shows that subjects asked about their reactions following participation in a deception experiment did indeed tend to indicate its acceptability. However, when asked to make a judgment about what reactions other students had to the same experiment, they expressed concern that others may have been harmed by the deception.For psychologists to selectively disregard the distinct possibility of dynamically motivated minimization of harm in order to justify deceptive research practices further supports Bok's characterization of today's competitive research environment and the standards of personal integrity that it challenges.Stephen Hahn-SmithDepartment of Psychology The University of New Mexico Albuquerque, NMReferencesChristensen, Larry. 1988.

The psychology of aesthetics and the arts is dedicated to the study of our experiences of the visual arts, music, literature, film, performances, architecture and design; our experiences of beauty and ugliness; our preferences and dislikes; and our everyday perceptions of things in our world. The Cambridge Handbook of the Psychology of Aesthetics and the Arts is a foundational volume presenting an overview of the key concepts and theories of the discipline where readers can learn about the questions that are (...) being asked and become acquainted with the perspectives and methodologies used to address them. The psychology of aesthetics and the arts is one of the oldest areas of psychology but it is also one of the fastest growing and most exciting areas. This is a comprehensive and authoritative handbook featuring essays from some of the most respected scholars in the field. (shrink)

The aesthetic experience may be defined as people's interactions with, and reactions to, objects, places, but also to the environment. Most psychological perspectives on the aesthetic experience argue that it results from the coordination of different mental processes such as perception, attention, memory, imagination, thought, and emotion. Physiological and neurological responses are also involved. Aesthetic experiences can take place while we observe works of art in museums and galleries as well as in other contexts such as natural and built environments. (...) Looking at a landscape, walking in a park, meeting people in a square, and walking into a building that is architecturally appealing are examples of natural and built environments where we can experience beauty, pleasure, attraction, and interest, among other aesthetic reactions.Research on aesthetic experiences has a long history, and in recent decades, the field has experienced tremendous growth in the number of empirical studies conducted. One of the areas that researchers have yet to fully address is the influence of the context (natural and built environments) on aesthetic experiences. We refer to context according to three broad categories: Context as natural environments, context as built environments, and environments for aesthetic experiences.Context as natural environments: People show a basic tendency to associate the natural environment with positive evaluations.

On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...) duration is still regarded as relative, but temporal succession is taken to be absolute. Following our approach, which is presented in more formal terms in, it is possible to conceive of a genuinely dynamical theory of quantum gravity within which time, in a substantive sense, remains. 1 Introduction1.1 The problem of time1.2 Our solution2 Understanding Symmetry2.1 Mechanics and representation2.2 Freedom by degrees2.3 Voluntary redundancy3 Understanding Time3.1 Change and order3.2 Quantization and succession4 Time and Gravitation4.1 The two faces of classical gravity4.2 Retaining succession in quantum gravity5 Discussion5.1 Related arguments5.2 Concluding remarks.

Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...) for formulating such characterizations in a computable fashion. Space object data are aligned with classes and relations in the Space Object Ontology and stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space domain awareness and the needs of spacecraft operators. This paper presents the core of the Space Object Ontology, discusses its advantages over other approaches to space object classification, and demonstrates its ability to combine diverse sets of data from multiple sources within an expandable framework. Finally, we show how the ontology provides benefits for enhancing and maintaining longterm space domain awareness. (shrink)

A novel approach to quantization is shown to allow for superpositions of the cosmological constant in isotropic and homogeneous mini-superspace models. Generic solutions featuring such superpositions display: i) a unitary evolution equation; ii) singularity resolution; iii) a cosmic bounce. Explicit cosmological solutions are constructed. These exhibit characteristic bounce features including a ‘super-inflation’ regime with universal phenomenology that can naturally be made to be insensitive to Planck-scale physics.

In this paper, I provide a philosophical analysis of Pāli texts that treat of a special kind of mental event called bhavaṅga citta. This mental event is a primal sentient consciousness, a passive form of basal awareness that individuates sentient beings as the type of being that they are. My aims with this analysis are twofold, one genealogical and reconstructive, the other systematic. On the genealogical and reconstructive side, I argue for a distinction between two kinds of continuity that are (...) at work in explaining the temporal structure of experience in Pāli Buddhist philosophy. Call these two forms of continuity ‘diachronic’ and ‘affective-motivational’ continuity, respectively. In my analysis of these two forms of continuity, I will focus on the coherence of bhavaṅga citta in its Abhidhammic context. My contention is that the commentarial account of bhavaṅga citta has the resources to explain diachronic continuity but struggles to give a fully workable account of affective-motivational continuity. I argue that the novel view of mental continuity offered by the early twentieth century Burmese monastic exegete Ledi Sayadaw offers another intriguing account of mental continuity, one that can help to explain affective-motivational continuity. Systematically speaking, in spelling out the dynamics of this distinction between types of mental continuity in connection with bhavaṅga, I offer a cross-cultural philosophical analysis of the deep structure of the mind and how affective processes below the threshold of ordinary habits of attention have a profound conditioning effect on our conscious relationship with the world.

Philosophy and model theory frequently meet one another. Philosophy and Model Theory aims to understand their interactions -/- Model theory is used in every ‘theoretical’ branch of analytic philosophy: in philosophy of mathematics, in philosophy of science, in philosophy of language, in philosophical logic, and in metaphysics. But these wide-ranging appeals to model theory have created a highly fragmented literature. On the one hand, many philosophically significant mathematical results are found only in mathematics textbooks: these are aimed squarely at mathematicians; (...) they typically presuppose that the reader has a significant background in mathematics; and little clue is given as to their philosophical significance. On the other hand, the philosophical applications of these results are then scattered across disconnected pockets of papers, separated by decades or more. -/- The first aim of Philosophy and Model Theory, then, is to consider the philosophical uses of model theory. On a technical level, we try to show how philosophically significant results connect to one another, and also to state the best version of a result for philosophical purposes. On a philosophical level, we show how similar dialectical situations arise repeatedly, across fragmented debates in varied philosophical areas. -/- The second aim of Philosophy and Model Theory, though, is to consider the philosophy of model theory. Model theory itself is rarely taken as the subject matter of philosophising (contrast this, say, with the philosophy of biology, or the philosophy of set theory). But model theory is a beautiful part of pure mathematics, and worthy of philosophical study in its own right. (shrink)

In this paper, I explore a debate between some Indian Buddhist schools regarding the nature of the underlying tendencies or anusaya-s. I focus here primarily on the ninth chapter of Kathāvatthu’s representation of a dispute about whether an anusaya can be said to have intentional object. I also briefly treat of Vasubandhu’s defense of the Sautrāntika view of anuśaya in the opening section of the fifth chapter his Abhidharmakośabhāṣyam. Following Vasubandhu, I argue against the Thervādin Abhidharmikas that the underlying tendencies (...) (anusaya-s) can be identified with their active manifestations (pariyuṭṭhāna). Etymologically, the notion of anusaya denotes a kind of latency, dormancy or otherwise ‘below the surface’ propensity. It can literally be translated as ‘that which lies or dwells beneath or alongside’. I will translate the term as ‘underlying tendency’, but philosophically speaking, it is most important to understand that the notion of anusaya refers to dispositions that condition current experience in a tacit way. The task of a philosophical account of the anusaya-s is to explain how their implicit conditioning influence shapes occurrent mental activity. The Indian Buddhist philosophers exercised an enormous amount of energy in attempting to explain this relation. A thorough examination of this dialectic has two important fruits to bear. The first is that the Buddhists can help us explain in precise detail how the mind is affectively layered. That is, they have a plausible account of how the mind is both responsive in real time to the objects it encounters in the world, while at the same time being tacitly conditioned by its own history of affective bias. Indeed, as we will see, the Buddhists were deeply concerned with how processes of affective bias were operating at the deepest levels of the mind and how we ought to conceive of their influence on our ordinary processes of perception and cognition. Second, this local position within the Buddhist milieu is indicative of a wider propensity in Buddhist philosophy to blend analyses of affectively-biased intentions and causation. I submit that this blending could be helpful in a more global for contemporary discussions of the mind in philosophy and science. (shrink)

Incarnate Word. Of the work’s fifteen books, Books 4 and 13 focus extensively on the soteriological and epistemological role of Christ, who, in his humility, conquered the pride of the devil and reopened humanity’s way to eternity. The Christology in these books plays an important role in Augustine’s argument by allowing his ascent to move from self-knowledge to contemplation of God. Indeed, it is his understanding of the Christological perfection of the imago dei which allows Augustine to discover a genuine imago trinitatis in human beings. For Augustine, the imago is observable in humanity to the extent that an individual is conformed to Christ, the perfect image of the invisible God. Thus, it is only through Christ that a human being can successfully contemplate the Trinity in this imago. (shrink)

The not-self teaching is one of the defining doctrines of Buddhist philosophical thought. It states that no phenomenon is an abiding self. The not-self doctrine is central to discussions in contemporary Buddhist philosophy and to how Buddhism understood itself in relation to its Brahmanical opponents in classical Indian philosophy. In the Pāli suttas, the Buddha is presented as making statements that seem to entail that there is no self. At the same time, in these texts, the Buddha is never presented (...) as saying explicitly that there is no self. Indeed, in the one discourse in which he is asked point blank whether there is a self, he refuses to answer. Thus, the suttas present us with a fundamental philosophical and interpretive problem: if the Buddha denies the existence of the self, why does he not state this denial explicitly? This paper resolves the problem by explaining why and how the Buddha can argue in a way that entails metaphysical anti-realism about the self while also refusing to state explicitly that there is no self.

Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and conjunction assessment presents major challenges. This is in part because in characterizing space objects we reference a variety of identifiers, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, operational processes, operational statuses, and so forth, which tend to be defined in highly heterogeneous and sometimes inconsistent (...) ways. The Space Domain Ontologies are designed to provide a consensus-based realist framework for formulating such characterizations in a way that is both consistent and computable. Space object data are aligned with classes and relations in a suite of ontologies built around the existing Space Object Ontology. They are stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space situational awareness and the needs of spacecraft operators and analysts. This paper provides an overview of the Space Domain Ontologies and their development and use. It presents the motivation for and advantages of the Space Domain Ontologies, including the benefits they provide for enhancing and maintaining long-term space situational awareness. (shrink)

The phenomenal overflow thesis states that the content of phenomenally conscious mental states can exceed our capacities of cognitive access. Much of the philosophical and scientific debate about the phenomenal overflow thesis has been focused on vision, attention, and verbal report. My view is that we feel things in our bodies that we don’t always process with the resources of cognitive access. Thinking about the question of phenomenal overflow from the perspective of embodied affect rather than the content of visual (...) experience is the novel contribution of this paper. I argue that we have reason to think that hydranencephalic children are phenomenally conscious but incapable of cognitive access. Further, I claim that we should interpret the reactive behavior of these subjects in terms of a kind of access to content that is distinct from cognitive access, I call this novel form of access ‘affective access.’.

In this paper, I explore how our experience of pain and suffering structure our experience over time. I argue that pain and suffering are not as easily dissociable, in living and in conceptual analysis, as philosophers have tended to think. Specifically, I do not think that there is only a contingent connection between physical pain and psychological suffering. Rather, physical pain is partially constitutive of existential suffering. My analysis is informed by contemporary thinking about pain and suffering as well as (...) Indian Buddhist philosophy. (shrink)

This paper concerns the way that phenomenal consciousness helps us to know things about the world. Most discussions of how consciousness contributes to our store of knowledge focus on propositional knowledge. In this paper, I recast the problem in terms of practical knowledge by reconstructing some neglected strands of argument in William James’s analyses of bodily affect and habitual action in The Principles of Psychology. I will argue that my reading of James’s view provides a plausible account of how phenomenally (...) conscious states feed practical knowledge. I will also show that my reconstruction of James view harmonizes well with recent empirical findings. (shrink)

We have begun work on two separate but related ontologies for the study of neurological diseases. The first, the Neurological Disease Ontology (ND), is intended to provide a set of controlled, logically connected classes to describe the range of neurological diseases and their associated signs and symptoms, assessments, diagnoses, and interventions that are encountered in the course of clinical practice. ND is built as an extension of the Ontology for General Medical Sciences — a high-level candidate OBO Foundry ontology that (...) provides a set of general classes that can be used to describe general aspects of medical science. ND is being built with classes utilizing both textual and axiomatized definitions that describe and formalize the relations between instances of other classes within the ontology itself as well as to external ontologies such as the Gene Ontology, Cell Ontology, Protein Ontology, and Chemical Entities of Biological Interest. In addition, references to similar or associated terms in external ontologies, vocabularies and terminologies are included when possible. Initial work on ND is focused on the areas of Alzheimer’s and other diseases associated with dementia, multiple sclerosis, and stroke and cerebrovascular disease. Extensions to additional groups of neurological diseases are planned. The second ontology, the Neuro-Psychological Testing Ontology (NPT), is intended to provide a set of classes for the annotation of neuropsychological testing data. The intention of this ontology is to allow for the integration of results from a variety of neuropsychological tests that assay similar measures of cognitive functioning. Neuro-psychological testing is an important component in developing the clinical picture used in the diagnosis of patients with a range of neurological diseases, such as Alzheimer’s disease and multiple sclerosis, and following stroke or traumatic brain injury. NPT is being developed as an extension to the Ontology for Biomedical Investigations. (shrink)

In this view from 2007–2009, the ethical challenges facing a potential global effort to control infectious disease are explored; they provide sobering insight into the challenges of later decades. Despite the devastating pandemic of HIV/AIDS that erupted in the early 1980s, despite the failure to eradicate polio and the emergence of resistant forms of tuberculosis that came into focus in the 1990s, and despite newly emerging diseases like Severe Acute Respiratory Syndrome (SARS) in 2003 and the fearsome prospect of human-to-human (...) avian flu, it is nevertheless a time of some excitement over prospects for effective control of much of infectious disease. Funded by national and international governmental and nongovernmental organizations (NGOs), private foundations, and even popular entertainers, large-scale new efforts are under way to address global killers like AIDS, tuberculosis, and malaria, among others. This “marvelous momentum” can be seen as part of a continuing effort from the time of Jenner onward. Extrapolating from this, we explore the notion of a “comprehensive global effort for the eradication, elimination or control of infectious disease”, with particular attention to the ethical issues that arise. This is to “think big” about disease-control efforts that are now often done in piecemeal ways. This chapter identifies five tracks along which such efforts need to be pursued: (1) national and international organizations and the development of collective will; (2) epidemiological and health care infrastructure; (3) scientific development; (4) religious, social, and cultural considerations; (5) legal and social protections for individuals and groups. Each of these poses significant ethical issues which, we argue, should be viewed in a comprehensive way, to ensure that practice, research, and policy in each of these areas understands the person with communicable infectious disease as both victim and (potential) vector.

Making research data readily accessible during a public health emergency can have profound effects on our response capabilities. The moral milieu of this data sharing has not yet been adequately explored. This article explores the foundation and nature of a duty, if any, that researchers have to share data, specifically in the context of public health emergencies. There are three notable reasons that stand in opposition to a duty to share one’s data, relating to: (i) data property and ownership, (ii) (...) just distribution of benefits and burdens and (iii) the contemporary ethos of science. We argue each reason can be successfully met with corresponding rationale in favour of data sharing. Further support for data sharing has been echoed in policies of health agencies, funding bodies and academic institutions; in documents on the ethical conduct of biomedical research; and in discussions on the nature of public health. From this, we ascertain that sharing data is the morally sound default position. This article then highlights the key roles reciprocity and solidarity play in supporting the practice of data sharing. We conclude with recommendations to regard public health research data as a common-pool resource in order to build a framework for stable data sharing management. (shrink)
