This paper describes an operational computer simulation of visual mental imagery in humans. The structure of the simulation was motivated by results of experiments on how people represent information in, and access information from, visual images. The simulation includes a “surface representation,” which is spatial and quasi‐pictorial, and an underlying “deep representation,” which contains “perceptual” information encoding appearance plus “propositional” information describing facts about an object. The simulation embodies a theory of how surface images are generated from deep representations, and (...) how surface images are processed when one accesses information embedded in them. The simulation also offers an account of various sorts of imagery transformations. (shrink)

The "great debate" in cognitive science today is about the nature of mental images. One side says images are basically pictures in the head. The other side says they are like the symbol structures in computers. If the picture-in-the-head theorists are right, then computers will never be able to think like people.This book contains the most intelligible and incisive articles in the debate, articles by cognitive psychologists, computer scientists and philosophers. The most exciting imagery phenomena are described, phenomena that indicate (...) that mental images can be rotated and scanned, that smaller images are harder to see than larger ones, that when mental images are made larger they eventually overflow, that the "screen" they overflow from has a determinable shape (elliptical), and that this "screen" subtends a determinate visual angle, the angle of vision of the mind's eye.Such experiments cry out for explanation. If images are pictures in the head, who (or what) looks at them? Why haven't brain scientists found them? Such questions are the subject of the great debate.IMAGERY is an excellent choice for courses in cognitive psychology, perception: artificial intelligence, computer science; philosophy of mind, of psychology and of science; minds and machines, science and society.Contributors include: Roger Brown and Richard Herrnstein (on the work of Roger N. Shepard), Daniel Dennett, Jerry Fodor, Robert Schwartz, Stephen Kosslyn, Steven Pinker, George Smith, Steven Shwartz, and Zenon Pylyshyn,. (shrink)

I argue that results in perception science do not support the claim that there is semantic perception or that typical, unreflective utterance comprehension is a perceptual process. Phenomena discussed include evidence-insensitivity, the Stroop effect, pop-out, and adaptation – as well as how these phenomena might relate to the function, format, and structure of perceptual representations. An emphasis is placed on non-inferential transitions from perceptual to conceptual representations, which are important for debates about the admissible contents of perception more generally.

Normality Does Not Equal Mental Health: The Need to Look Elsewhere for Standards of Good Mental Health is the first book to question the equation of psychological normality and mental health. It is also the first book to take contemporary psychiatry and clinical psychology to task for deeply flawed thinking when they accept the diagnostic system propounded by the DSM, which reifies syndromes into alleged “mental disorders.” Where Thomas Szasz argued that “mental disorders” are myths, Bartlett makes the much more (...) damaging charge that reifying mental disorders involves a provable form of fallacious thinking, producing a variety of epistemological nonsense. /// -/- -/- The author weighs the evidence, and with strict logic, compelling evidence, and careful analysis, challenges the current paradigm of mental health theorists and practitioners. Never has the case against the standard of psychological normality and against the non-scientific creation of “mental disorders” been made with such boldness, multidisciplinary knowledge, solid scholarship, and clarity of language. /// -/- -/- Normality Does Not Equal Mental HealthAlthough the need to question psychological normality as a satisfactory standard of good mental health has been staring us in the face for a long time, no one, clinical professional or scholar, has had the courage or the intellectual willingness to face with unflinching honesty the shortcomings and disappointments of psychological normality and to propose that we should look elsewhere for standards of good psychological health. /// -/- -/- Contemporary psychiatry and clinical psychology, on the contrary, base their conception of mental health on the standard of psychological normality. This supposition has come to be accepted uncritically and without question, and yet it has become fundamental to current clinical theory and practice, and forms the core of the psychiatric classification system of the DSM, which has become today’s diagnostic authority. /// -/- -/- While touting today’s scientific gold standard of “evidence-based” research, DSM’s authoritative classification of “mental disorders” is itself hardly “evidence-based,” for it is recognized, but seldom emphasized, that the majority of DSM’s “mental disorders” have no known empirical, organic basis. /// -/- -/- Normality Does Not Equal Mental Health takes DSM to task not only for its failure to adhere to today’s evidence-based standard, but for its failure to rein in its highly speculative diagnostic labeling, in accordance with the modern paradigm of rigorous science, which repudiates metaphorical reifications whose alleged validity rests only on the voting preferences of a professional membership. /// -/- -/- The book is a carefully argued critique of the dominant assumption in current psychiatry and clinical psychology that psychological normality is fundamental to mental health and therefore good. In place of this unsatisfactory presumption, Normality Does Not Equal Mental Health proposes a positive and constructive revision in our understanding of mental health and of our conception of mental disorders.

Philosophy and Phenomenological Research, EarlyView.

Philosophers have not resisted temptation to transgress against the logic of their own conceptual structures. Self-undermining position-taking is an occupational hazard. Philosophy stands in need of conceptual therapy. The author describes three conceptions of philosophy: the narcissistic, disputatious, and therapeutic. (i) Narcissistic philosophy is hermetic, believing itself to contain all evidence that can possibly be relevant to it. Philosophy undertaken in this spirit has led to defensive, monadically isolated positions. (ii) Disputatious philosophies are fundamentally question-begging, animated by assumptions that philosophical (...) adversaries reject. (iii) The intention of therapeutic philosophy is to study philosophical positions from the standpoint of their internal consistency, or lack of it. In particular, its interest is in positions that either compel assent, because they cannot be rejected without self-referential inconsistency, or self-destruct because self-referential inconsistency cannot be avoided. The article's focus is on the latter. Several examples of self-undermining positions are drawn from the history of philosophy, exemplifying two main varieties of self-referential inconsistency: pragmatical and projective. (shrink)

An incisive and witty probe into ethics of the academic world.

From the Editor’s Introduction: "The Internal Limitations of Human Understanding." We carry, unavoidably, the limits of our understanding with us. We are perpetually confined within the horizons of our conceptual structure. When this structure grows or expands, the breadth of our comprehensions enlarges, but we are forever barred from the wished-for glimpse beyond its boundaries, no matter how hard we try, no matter how much credence we invest in the substance of our learning and mist of speculation. -/- The limitations (...) in view here are not due to the mere finitude of our understanding of ourselves and of the world in which we live. They are limitations that come automatically and necessarily with any form of understanding. They are, as we shall see, part and parcel of any organization or ordering of data that we call information. -/- The consequences of these limitations are varied: As a result of them, hermeneutics cannot help but be hermetic; scientific theories of necessity are circumscribed by the boundaries of the ideas that define them; formal systems must choose between consistency and comprehensiveness; philosophical study, because it includes itself within its own proper subject matter, is forced to be reflexive in its self-enclosure. The fundamental dynamic shared by all forms of understanding testifies to an internal limitative keystone. (shrink)

New brain-computer interface and neuroimaging techniques are making differentiation less ambiguous and more accurate between unresponsive wakefulness syndrome patients and patients with higher cognitive function and awareness. As research into these areas continues to progress, new ethical issues will face physicians of patients suffering from total locked-in syndrome, characterized by complete loss of voluntary muscle control, with retention of cognitive function and awareness detectable only with neuroimaging and brain-computer interfaces. Physicians, researchers, ethicists and hospital ethics committees should be aware of (...) and prepared to handle ethical issues unique to these totally locked-in patients. Several thought experiments are discussed, to highlight potential ethical dilemmas surrounding surrogate decision-making, autonomy, end-of-life care, and pediatric care, which will be unique to total LIS patients. These, along with other ethical problems especially relevant to total LIS patients, merit further discussion among physicians, researchers, ethicists and hospital ethics committees, to facilitate consensus regarding these issues, and improve patient care.

This paper explores the relationship between intuition and flow from a neurodynamics perspective. Flow and intuition represent two cognitive phenomena rooted in nonconscious information processing; however, there are clear differences in both their phenomenal characteristics and, more broadly, their contribution to action and cognition. We propose, extrapolating from dual processing theory, that intuition serves as a rapid, nonconscious decision-making process, while flow facilitates this process in action, achieving optimal cognitive control and performance without [conscious] deliberation. By exploring these points of (...) convergence between flow and intuition, we also attempt to reconcile the apparent paradox of the presence of enhanced intuition in flow, which is also a state of heightened cognitive control. To do so, we utilize a revised dual-processing framework, which allows us to productively align and differentiate flow and intuition (including intuition in flow). Furthermore, we draw on recent work examining flow from an active inference perspective. Our account not only heightens understanding of human cognition and consciousness, but also raises new questions for future research, aiming to deepen our comprehension of how flow and intuition can be harnessed to elevate human performance and wellbeing.

The philosophical, legal, and HCI literature concerning artificial intelligence (AI) has explored the ethical implications and values that these systems will impact on. One aspect that has been only partially explored, however, is the role of deception. Due to the negative connotation of this term, research in AI and Human–Computer Interaction (HCI) has mainly considered deception to describe exceptional situations in which the technology either does not work or is used for malicious purposes. Recent theoretical and historical work, however, has (...) shown that deception is a more structural component of AI than it is usually acknowledged. AI systems that enter in communication with users, in fact, forcefully invite reactions such as attributions of gender, personality and empathy, even in the absence of malicious intent and often also with potentially positive or functional impacts on the interaction. This paper aims to operationalise the Human-Centred AI (HCAI) framework to develop the implications of this body of work for practical approaches to AI ethics in HCI and design. In order to achieve this goal, we take up the analytical distinction between “banal” and “strong” deception, originally proposed in theoretical and historical scholarship on AI (Natale in Deceitful media: artificial intelligence and social life after the turing test, Oxford University Press, New York, 2021), as a starting point to develop ethical reflections that will empower designers and developers with practical ways to solve the problems raised by the complex relationship between deception and communicative AI. The paper considers how HCAI can be applied to conversational AI (CAI) systems in order to design them to develop banal deception for social good and, at the same time, to avoid its potential risks.

In this paper, the author attempts to make explicit certain of the key variables that underlie the wide variety of positions which have been offered in answer to the question posed by the title of the paper. Several positions are reviewed briefly, ranging from Bertrand Russell’s to Jasper’s to Milton Meyer’s to Thoreau’s. These are then considered as a group in terms of possible systems of values which traditionally have formed the basis for condemnations or defenses of political and social (...) silence, of marginal commitment, or of individual nonparticipation or complicity. The author does not hope to settle the issue, but rather to increase our sensitivity to it, and to its complexity. (shrink)

Starting with Kant’s undeveloped proposal of a “negative science,” the author describes how philosophy may be developed and strengthened by means of a systematic approach that seeks to identify and eliminate a widespread but seldom recognized form of systemic and propagating conceptual error. ¶¶¶¶¶ -/- The paper builds upon the author’s book, CRITIQUE OF IMPURE REASON: HORIZONS OF POSSIBILITY AND MEANING (Studies in Theory and Behavior, 2021). ¶¶¶¶¶ -/- The author’s purpose is twofold: first, to enable us to recognize the (...) boundaries of what is referentially forbidden—the limits beyond which reference becomes meaningless—and second, to avoid falling victims to a certain broad class of conceptual confusions that lie at the heart of many major philosophical problems. By realizing these objectives, the boundaries of possible meaning are determined. (shrink)

We survey the meta-ethical tools and institutional processes that traditional Islamic ethicists apply when deliberating on bioethical issues. We present a typology of these methodological elements, giving particular attention to the meta-ethical techniques and devices that traditional Islamic ethicists employ in the absence of decisive or univocal authoritative texts or in the absence of established transmitted cases. In describing how traditional Islamic ethicists work, we demonstrate that these experts possess a variety of discursive tools. We find that the ethical responsa—i.e., (...) the products of the application of the tools that we describe—are generally characterized by internal consistency. We also conclude that Islamic ethical reasoning on bioethical issues, while clearly scripture-based, is also characterized by strong consequentialist elements and possesses clear principles-based characteristics. The paper contributes to the study of bioethics by familiarizing non-specialists in Islamic ethics with the role, scope, and applicability of key Islamic ethical concepts, such as “aims” (maqāṣid), “universals” (kulliyyāt), “interest” (maṣlaḥa), “maxims” (qawā`id), “controls” (ḍawābit), “differentiators” (furūq), “preponderization” (tarjīḥ), and “extension” (tafrī`).

Two fundamentally distinct approaches to the teaching of philosophy are contrasted: On the one hand, there is the “information-oriented” approach which has dominated classrooms and which emphasizes the understanding of historically important philosophical works. On the other hand, there is the “cognitive skills” approach. The two approaches may be distinguished under the headings of ‘knowing that’ as opposed to ‘knowing how’. This paper describes and discusses four perspectives relating to the teaching of cognitive skills: (i) the discovery-oriented approach, (ii) Piagetian (...) learning cycles, (iii) protocol analysis, and (iv) conceptual therapy. The latter approach reflects the author’s interest in helping students to develop “therapeutic” skills that enable them to identify and eliminate concepts which they employ in their thinking and which are incompatible with their own presuppositional bases and are therefore self-refuting. ●●●●● -/- 2022 UPDATE: The approach of this paper has been updated and developed further in Appendix II, "Epistemological Intelligence," of the author’s 2021 book _Critique of Impure Reason: Horizons of Possibility and Meaning_. The book is available both in a printed edition (under ISBN 978-0-578-88646-6 from Barnes & Noble, Amazon, and other booksellers) and an Open Access eBook edition (available through Philpapers under the book’s title and other philosophy online archives).

Emotion expressions convey valuable information about others’ internal states and likely behaviours. Accurately identifying expressions is critical for social interactions, but so is perceiver confidence when decoding expressions. Even if a perceiver correctly labels an expression, uncertainty may impair appropriate behavioural responses and create uncomfortable interactions. Past research has found that perceivers report greater confidence when identifying emotions displayed by cultural ingroup members, an effect attributed to greater perceptual skill and familiarity with own-culture than other-culture faces. However, the current research (...) presents novel evidence for an ingroup advantage in emotion decoding confidence across arbitrary group boundaries that hold culture constant. In two experiments using different stimulus sets participants not only labeled minimal ingroup expressions more accurately, but did so with greater confidence. These results offer novel evidence that ingroup advantages in emotion decoding confidence stem partly from social-cognitive processes. (shrink)

Discusses the bases of moral development, based on a review of relevant literature. L. Kohlberg's cognitive structural theory of moral development prescribes abstract egalitarianism as the ideal form of moral reasoning. It is argued that this conceptualization represents an overly modernist, individualist reading of Platonic moral philosophy. H. G. Gadamer , in contrast, sees Plato teaching that virtue is learned implicitly, through exemplifying a virtuous person. Belief that virtue must be justified rationally leads to the dissolution of social, communal bases (...) of moral learning. His view suggests a more humanly relevant rendering of Platonic moral reasoning than that suggested by Kohlberg. This view suggests the possibility that virtue is irreducibly social, seen in the meaningful differences that acts have for others, and in implicit interpersonal relatedness. 2012 APA, all rights reserved).

The civil rights movement has broken away from its religious roots which once provided it firm support and, indeed, it has become a threat to those roots. In fact, the past thirty years evidence two civil rights movements. The original civil rights movement promoted equal opportunity and presupposed a constrained vision of human possibilities compatible with Christianity, The revised civil rights agenda, which had replaced it by 1971, promoted preferential policies dubbed "affirmative action" based on an unconstrained vision incompatible with (...) both Christianity and the American founding. The most visible threat to religious liberty is the expansion of civil rights protections to include homosexuals despite the overwhelming rejection of homosexuality as a lifestyle by the majority of Americans, including Christians.

Both the sociology of knowledge and the philosophy of science are centrally concerned with the succession of scientific beliefs. In case studies of scientific debates, however, the emphasis tends to be placed on the outcome of disputes. This paper proposes that attention should instead be focused on the process of debate: that is, on scientific argumentation. It is shown how such a focus circumvents many traditional epistemological problems concerning the truth-status of scientific knowledge. By reference to the consensus conception of (...) truth, it is claimed that scientific arguments can be studied naturalistically whilst still honouring the orientation towards truth exhibited by scientists. Finally, the paper offers a brief résumé of recent studies indicating how this naturalistic study of scientific argumentation can be developed through the sociology of language. (shrink)

The literature on the politics of science and on science policy is dominated by information about large and highly industrialized countries. For example, models of the different forms of science policy administration and management tend to derive from French, U.S., and British exemplars. Yet in the mid-1990s there is a growing number of small nations, all of which are seeking to harness research communities to the cause of socioeconomic development, while still extracting "value for money" from science budgets. This article (...) uses the case study approach—focusing on the political economy of the politics of science in the Irish Republic, chiefly since the 1950s-to analyze the problems faced by science policy agencies and the scientific community in small nations. The study offers analogies and possible insights into the politics of research policy in other small nations ; it also aims to throw light on emerging research policy trends even in bigger countries as the "bargain" between the funders and the performers of research becomes more and more explicit and increasingly subject to economic justifications.
