Michael Dummett begins The Logical Basis of Metaphysics by noting that most of the work done in analytic philosophy seems disconcertingly remote from any concern with the “deep questions of great import for an understanding of the world” that the non-professional expects it to answer. In part, he says, this is because modern analytic philosophy is founded upon a more penetrating analysis of the general structure of our thoughts than was available to past ages, namely, the apparatus of modern logic, (...) beginning with Frege’s Begriffsschrift in 1879. Analytic philosophers take for granted the principles of semantic analysis embodied in the notation of modern logic. Even if they do not make use of a technical vocabulary, having taken these principles for granted is itself often enough to render their approach opaque to the layperson. Appearances aside, he claims, analytic philosophy is still concerned with the “deep questions.” And, to his credit, Dummett keeps an eye focused on some of the central questions of philosophy, those concerning metaphysical realism, throughout the book.

Dieses Buch ist ein Klassiker der philosophischen Anthropologie und Arnold Gehlens wichtigstes Buch. Es fasst Gehlens Modell vom Menschen als eines auf Handlung und kulturelle Kompensation angewiesenen und sich damit eigentatig von der ihn bedrohenden Umwelt entlastenden "Mangelwesens" gultig zusammen. Auch wurde in "Der Mensch" 1950 erstmals Gehlens Institutionenlehre skizziert, die er aus der Revision seiner ursprunglichen Theorie "oberster Fuhrungssysteme" entwickelte. Gehlens Hauptwerk war "ohne Zweifel der fortgeschrittenste Versuch, die Philosophische Anthropologie an die Erkenntnisse empirischer Disziplinen zu binden". Diese (...) Ausgabe bringt die textkritische Edition der Kritischen Gesamtausgabe mit dem Text der 4. Auflage von 1950, der die letzte tiefgreifende Umarbeitung darstellt, die Gehlen an dem erstmals 1940 erschienenen Text vornahm. (shrink)

Michael Dummett has claimed that analytic philosophy is distinguished from other schools in its belief that a comprehensive philosophical account of thought can only be attained by developing a philosophical account of language. Dummett himself argues persuasively for the priority-of-Ianguage thesis. This, in effect, metaphilosophical position is of special importance for his more straightforwardly philosophical views, for he holds that philosophical investigations of the concepts of objectivity and reality grow directly out of the philosophy of thought. But I argue that (...) some of what Dummett says about the priority of language over thought is problematic, that there may yet be a serious role for concepts within the theory of meaning, and that Dummett’s failure to acknowledge this role both hobbles his account of linguistic understanding and has deleterious consequences for his discussions of metaphysical realism-robbing him of the resources with which he might have avoided some of his anti-realist conclusions.

In this book, Arnold Davidson elaborates a method for considering the history of concepts and the nature of scientific knowledge, a method he calls "historical epistemology." He applies this to the history of sexuality, with consequences for our understanding of desire, abnormality, and sexuality.

From social media to search engines to Wikipedia, the internet is thoroughly embedded in how we produce, locate, and share knowledge around the world. Who Should We Be Online? provides an account of online knowledge that takes seriously the role of sexist, racist, transphobic, colonial, and capitalist forms of oppression. Frost-Arnold argues against analyzing internet users as a collection of identical generic people with smartphones. The novel epistemology developed in this book recognizes that we are differently embodied beings interacting (...) within systems of dominance. Our social identities and global inequalities shape who we are, who we can be online, and what we know. Tackling problems of online content moderation, fake news, and hoaxes, Frost-Arnold shows that oppressive online structures and practices help fuel ignorance. But she also reveals how the internet provides opportunities for marginalized people and activists to share knowledge online. Drawing on feminist accounts of objectivity, veritistic social epistemology, epistemologies of ignorance, virtue epistemology, and the epistemic injustice literature, this book argues for a social epistemology that values truth and objectivity, while recognizing that inequalities shape our collective ability to attain these goals. Timely and interdisciplinary, Who Should We Be Online? weaves together internet studies scholarship from across the humanities, social sciences, and computer science. Presenting case studies of moderators, imposters, tricksters, fakers, and lurkers, this book both explains the problems with our current internet ecosystem and imagines liberatory online futures.

Most people will agree that if my brain were made to have within it precisely the same pattern of activity that is in it now but through artificial means, as in its being fed all its stimulation through electrodes as it sits in a vat, an experience would result for me that would be subjectively indistinguishable from that I am now having. In ‘The Story of a Brain’ I ask whether the same subjective experience would be maintained in variations like (...) these: The hemispheres are in different vats but interacting with each other through radio transmission. Smaller chunks - and eventually the individual neurons - are interacting in this way. The hemispheres or the smaller chunks undergo internally the same pattern of activity but without interacting with each other. (shrink)

The purpose of cognitive diagnostic modeling is to classify students' latent attribute profiles using their responses to the diagnostic assessment. In recent years, each diagnostic classification model makes different assumptions about the relationship between a student's response pattern and attribute profile. The previous research studies showed that the inappropriate DCMs and inaccurate Q-matrix impact diagnostic classification accuracy. Artificial Neural Networks have been proposed as a promising approach to convert a pattern of item responses into a diagnostic classification in some research (...) studies. However, the ANNs methods produced very unstable and unappreciated estimation unless a great deal of care was taken. In this research, we combined ANNs with two typical DCMs, the deterministic-input, noisy, “and” gate model and the deterministic-inputs, noisy, “or” gate model, within a semi-supervised learning framework to achieve a robust and accurate classification. In both simulated study and real data study, the experimental results showed that the proposed method could achieve appreciated performance across different test conditions, especially when the diagnostic quality of assessment was not high and the Q-matrix contained misspecified elements. This research study is the first time of applying the thinking of semi-supervised learning into CDM. Also, we used the validating test to choose the appropriate parameters for the ANNs instead of using typical statistical criteria. (shrink)

Cet article soutient que les voitures autonomes sont des robots sociaux qui doivent agir comme des tenants-lieux de leurs propriétaires humains. Pour ne pas esquiver les choix moraux incombant aux utilisateurs humains de ces technologies, on pourrait programmer les véhicules de façon à ce qu’ils puissent se comporter selon différentes théories morales, en permettant aux propriétaires de choisir celle qui a leur préférence. L’article envisage également les implications éthiques d’autres problèmes pratiques liés à la technologie des voitures autonomes.

The traditional verbal/nonverbal dichotomy is inadequate for completely describing cerebral lateralization. Musical functions are not necessarily mediated by the right hemisphere; evidence for a specialist left-hemisphere mechanism dedicated to the encoded speech signal is weakening, and the right hemisphere possesses considerable comprehensional powers. Right-hemisphere processing is often said to be characterized by holistic or gestalt apprehension, and face recognition may be mediated by this hemisphere partly because of these powers, partly because of the right hemisphere's involvement in emotional affect, and (...) possibly through the hypothesized existence of a specialist face processor or processors in the right. The latter hypothesis may, however, suffer the same fate as the one relating to a specialist encodedness processor for speech in the left. Verbal processing is largely the province of the left because of this hemisphere's possession of sequential, analytic, time-dependent mechanisms. Other distinctions are special cases of an analytic/holistic dichotomy. More fundamentally, however, the left hemisphere is characterized by its mediation of discriminations involving duration, temporal order, sequencing, and rhythm, at thesensory level, and especially at themotorlevel. Spatial aspects characterize the right, the mapping of exteroceptive body space, and the positions of fingers, limbs, and perhaps articulators, with respect to actual and target positions. Thus there is a continuum of function between the hemispheres, rather than a rigid dichotomy, the differences being quantitative rather than qualitative, of degree rather than of kind. (shrink)

I critically examine Nietzsche’s argument in The Will to Power that all the detailed events of the world are repeating infinite times (on account of the merely finite possible arrangements of forces that constitute the world and the inevitability with which any arrangement of force must bring about its successors). Nietzsche celebrated this recurrence because of the power of belief in it to bring about a revaluation of values focused wholly on the value of one’s endlessly repeating life. Belief in (...) recurrence would bring joy to those who had achieved excellence in this life and crush those who had not. I point out, however, that this significance of recurrence must be spoiled by the consideration that within each of the long cycles of recurrence there would have to be, as well, countless variations of this life. And I consider the issue of personal identity within such recurrences. Is it the same person or merely resembling but distinct persons in the recurrences or the variations? If it is the same person in precise recurrences, should the subjectively identical experience be thought of as really additional for that person? (shrink)

I argue that a certain type of naturalist should not accept a prominent version of the no-miracles argument (NMA). First, scientists (usually) do not accept explanations whose explanans-statements neither generate novel predictions nor unify apparently disparate established claims. Second, scientific realism (as it appears in the NMA) is an explanans that makes no new predictions and fails to unify disparate established claims. Third, many proponents of the NMA explicitly adopt a naturalism that forbids philosophy of science from using any methods (...) not employed by science itself. Therefore, such naturalistic philosophers of science should not accept the version of scientific realism that appears in the NMA. (shrink)

Life goals or aspirations can be distinguished as intrinsic or extrinsic, with different implications for well-being. In this study we used network analysis to reexamine this intrinsic-extrinsic distinction, illustrating how novel candidate aspirations can be mapped along this dimension using innovative methods. We identify four previously unexamined life aspirations, predicting that aspiring for power and social adherence would group with extrinsic goals, whereas aspiring for self-expression and mastery would group with intrinsic goals. In two samples (n = 196; n = (...) 346) we analyze both the original life-goal variables and these novel aspirations using factor analysis, multidimensional scaling, circumplex modeling, and a network analysis using a graphical least absolute shrinkage and selection operator (glasso) to estimate the network structure of aspirations using EBIC. Replicating past intrinsic-extrinsic distinctions, all four methods further classified power and social adherence as extrinsic goals, and self-expression and mastery as intrinsic goals. The intrinsic-extrinsic distinction was also clearly visible in the network analysis. Finally, consistent with hypotheses, power and social adherence were unrelated to wellness indicators, whereas self-expression and mastery correlated positively with well-being indicators and negatively with ill-being indicators, supporting their hypothesized nature as extrinsic and intrinsic, respectively.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dialogue Between an Orthodox and a Barlaamite, and: The Ground of Union: Deification in Aquinas and PalamasDavid BradshawSaint Gregory Palamas. Dialogue Between an Orthodox and a Barlaamite. Translated by Rein Ferweda with Introduction by Sara J. Denning-Bolle. Binghamton, NY: Global Publications/CEMERS, 1999. Pp. 108. Paper, $17.00.A. N. Williams. The Ground of Union: Deification in Aquinas and Palamas. New York and Oxford: Oxford University Press, 1999. Pp. 222. Cloth, (...) $49.95.Gregory Palamas (1296-1359) was a Byzantine monk who rose to become Archbishop of Thessalonica and a leading theologian of the Orthodox Church. He is best known for his role in the hesychast controversy. The hesychasts (from hesychia, silence) were monks of Mount Athos who claimed that through prayer and ascetic struggle they had been enabled to see God with their bodily eyes. More precisely, they claimed to see a kind of divine radiance permeating all things, including their own bodies. They insisted that this light was not a created reality but was God himself as he manifested himself to them.When the hesychasts were attacked by an Italian monk named Barlaam, Palamas rose to their defense. The challenge he faced was that of explaining how the transcendent God could be visible to human eyes. His answer was to adapt two terms long in use in other areas of theology, ousia (substance, essence) and energeia (activity, operation). He held that whereas the ousia of God is unknowable to any created intellect, the divine energeiai can be shared in by creatures, who are thereby deified. The "uncreated light" of the monks is simply the divine energeia as it had become visible to the monks through the purification of the heart achieved by prayer, asceticism, and obedience to the divine commandments. Gregory's defense of the hesychasts was endorsed by a series of synods at Constantinople, and to this day he is commemorated in Orthodox churches on the second Sunday in Lent.The importance of Palamas for the history of philosophy lies in the fact that he presents a version of Christian thought that is deeply rooted in tradition, and by most standards fully orthodox, yet owes nothing to western scholasticism. A quick comparison [End Page 586] with Aquinas reveals several points of divergence. (1) Whereas Aquinas holds that all the divine attributes and activities are identical with the divine essence, the distinctions among them being merely quoad nos, Palamas holds that the distinction between the divine ousia and energeia is not just imposed by our perspective but is truly present in God. (2) Whereas Aquinas says little about deification and explicitly reserves the vision of the divine essence to the afterlife, Palamas insists that deification is possible in this life and that the condition of those who experience it is similar (though of course not identical) to that of the blessed after the resurrection. (3) Whereas Aquinas allows that the blessed ultimately do attain a vision of the divine essence, Palamas holds that the divine ousia is intrinsically unknowable to creatures.Whether these differences are as sharp as they seem is a matter that requires careful investigation. The first of the two works under review, Palamas's Dialogue Between an Orthodox and a Barlaamite, is to be welcomed for the clarification it provides of Palamas's views. It is the third of his major works to be translated into English, the others being Triads in Defense of the Holy Hesychasts and One Hundred and Fifty Chapters. I confess to finding it less engaging than the other two; it lacks the freshness and vigor of the Triads (Palamas's earliest work) and the wide-ranging systematic character of the Chapters. Nonetheless, it does provide a helpful elaboration of the ousia -energeia distinction, particularly in the argument (88-90) that such a distinction does not compromise divine simplicity.The second work, The Ground of Union: Deification in Aquinas and Palamas by A. N. Williams, is the first book-length comparison of these two pivotal figures. It is a revision of the author's doctoral dissertation, and has a certain plodding dryness characteristic of the genre; nonetheless, it is clear and well-informed, and Williams is... (shrink)

I provide an account of the cognitive attitude of trust that explains the role trust plays in the planning of rational agents. Many authors have dismissed choosing to trust as either impossible or irrational; however, this fails to account for the role of trust in practical reasoning. A can have therapeutic, coping, or corrective reasons to trust B to ${\phi}$ , even in the absence of evidence that B will ${\phi}$ . One can choose to engage in therapeutic trust to (...) inspire trustworthiness, coping trust to simplify one’s planning, or corrective trust to avoid doing a testimonial injustice. To accommodate such types of trust, without accepting doxastic voluntarism, requires an account of the cognitive attitude of trust broader than belief alone. I argue that trust involves taking the proposition that someone will do something as a premise in one’s practical reasoning, which can be a matter of believing or accepting the proposition. I defend this account against objections that it (i) provides insufficient rational constraints on trust, (ii) conflates trust and pretense of trust, and (iii) cannot account for the rationality of back-up planning.

During the academic year 1940-1941, several giants of analytic philosophy congregated at Harvard, holding regular private meetings, with Carnap, Tarski, and Quine. Carnap, Tarski, and Quine at Harvard allows the reader to act as a fly on the wall for their conversations. Carnap took detailed notes during his year at Harvard. This book includes both a German transcription of these shorthand notes and an English translation in the appendix section. Carnap’s notes cover a wide range of topics, but surprisingly, the (...) most prominent question is: If the number of physical items in the universe is finite, what form should scientific discourse take? This question is closely connected to an abiding philosophical problem: What is the relationship between the logico-mathematical realm and the material realm? Carnap, Tarski, and Quine’s attempts to answer this question involve issues central to philosophy today.This book focuses on three such issues: nominalism, the unity of science, and analyticity. In short, the book reconstructs the lines of argument represented in these Harvard discussions, discusses their historical significance (especially Quine’s break from Carnap), and relates them when possible to contemporary treatments of these issues.

This article offers an analysis of marketing as an ideological set of practices that makes cultural interventions designed to infuse social relations with biopolitical injunctions. We examine a contemporary site of heightened attention within marketing: the rise of online communities and the attendant profession of social media marketing managers. We argue that social media marketers disavow a core problem; namely, that the object at stake, the customer community, barely exists. The community therefore functions ideologically. We describe the ideological gymnastics necessary (...) for maintaining momentum behind a practice that barely exists and we ponder why such ideologies are necessary, and what they allow the marketer to do. Working with such concepts as ‘the wild’, ‘communicative capitalism’, and ‘biopolitical marketing’, we explore a genre of popular business literature that proselytizes for online customer communities and we reflect on the broader implications.

This volume also includes several important works by Foucault previously unpublished in English. The other contributors are Georges (...) Canguilhem, Gilles Deleuze, Jacques Derrida, Pierre Hadot, Michel Serres, and Paul Veyne. Here for the first time is the French Foucault. This volume offers lucid and important texts that will appeal to students and professors at every level of study.

Since anonymous agents can spread misinformation with impunity, many people advocate for greater accountability for internet speech. This paper provides a veritistic argument that accountability mechanisms can cause significant epistemic problems for internet encyclopedias and social media communities. I show that accountability mechanisms can undermine both the dissemination of true beliefs and the detection of error. Drawing on social psychology and behavioral economics, I suggest alternative mechanisms for increasing the trustworthiness of internet communication.

The idea that simplicity matters in science is as old as science itself, with the much cited example of Ockham's Razor, 'entia non sunt multiplicanda praeter necessitatem': entities are not to be multiplied beyond necessity. A problem with Ockham's razor is that nearly everybody seems to accept it, but few are able to define its exact meaning and to make it operational in a non-arbitrary way. Using a multidisciplinary perspective including philosophers, mathematicians, econometricians and economists, this 2002 monograph examines simplicity (...) by asking six questions: what is meant by simplicity? How is simplicity measured? Is there an optimum trade-off between simplicity and goodness-of-fit? What is the relation between simplicity and empirical modelling? What is the relation between simplicity and prediction? What is the connection between simplicity and convenience? The book concludes with reflections on simplicity by Nobel Laureates in Economics.

Experience with electronic communication in ethics committees at two hospitals is reviewed and discussed. A listserver of ethics committee members transmitted a synopsis of the ethics consultation shortly after the consultation was initiated. Committee comments were sometimes incorporated into the recommendations. This input proved to be most useful in unusual cases where additional, diverse inputs were informative. Efforts to ensure confidentiality are vital to this approach. They include not naming the patient in the e-mail, requiring a password for access to (...) the listserver, and possibly encryption. How this electronic communication process alters group interactions in ethics committees is a fruitful area for future investigation. (shrink)

Gehlen's core idea in Man is that humans have unique properties which distinguish them from all other species: 1. world-openness, a concept originally coined by Max Scheler, which describes the ability of humans to adapt to various environments (as contrasted with animals, which can only survive in environments which match their evolutionary specialisation). This gives us 2. the ability to shape our environment according to our intentions, and it comprises a view of language as a way of acting (Gehlen was (...) one of the first proponents of speech act theory), Human beings are also marked 3. by an excess of impulses and by 4. the ability of self-control. These properties allow us (again in contrast to all other animals) 5. to create our own (for example cultural) environments. Gehlen's philosophy has influenced many contemporary German thinkers in a range of disciplines, including Peter L. Berger, Thomas Luckmann and Niklas Luhmann in sociology, and Hans Blumenberg in philosophy. (shrink)

This book traces the development of conceptions of God and the relationship between God's being and activity from Aristotle, through the pagan Neoplatonists, to thinkers such as Augustine, Boethius and Aquinas and Dionysius the Areopagite, Maximus the Confessor and Gregory Palamas. The result is a comparative history of philosophical thought in the two halves of Christendom, providing a philosophical backdrop to the schism between the Eastern and Western Churches.

Auch seine letzte Monographie Moral und Hypermoral sah Gehlen in der direkten Nachfolge seines anthropologischen Hauptwerkes Der Mensch. Insofern verstand er seinen Entwurf einer pluralistischen Ethik als Konkretisierung seiner Lehre vom Menschen. In diesem Buch, das eine Genealogie der Moralen entwickeln will, stellte sich Gehlen die Aufgabe, Anthropologie, Verhaltensforschung und Soziologie so zu verbinden, dass vier voneinander nicht ableitbare Ethosformen empirisch freigelegt werden konnten: von einem aus der aGegenseitigkeit entwickelten Ethos uber Eudaimonismus und Humanitarismus bis hin zu einem Ethos der (...) Institutionen einschliesslich des Staates. Gehlen wollte der abstrakten Ethik der Aufklarung widersprechen, wie sie beispielsweise in Voltaires Diktum zum Ausdruck kam, nach welchem es nur eine Moral gebe, so wie es nur eine Geometrie gibt. Systematisch geht es in erster Linie um eine anthropologische Begrundung der Ethik, d.h. um eine Mehrheit moralischer Instanzen und Sozial-Regulationen. Diese werden nicht evolutionar interpretiert, d.h. als Fortschritt von der Nahethik zu einer schliesslich weltumspannenden Moralitat. Manche Moralen konnen als instinktnah angenommen werden, andere ergeben sich aus den Notwendigkeiten bestimmter Institutionen. Immer jedoch sind sie kulturell geformt und zugleich auf unterschiedlichen Ebenen der Abstraktion angesiedelt. Es bleibt im Zuge einer neuerlichen Rezeption von Moral und Hypermoral die These zu prufen, ob die Modellvorstellung eines unversohnlichen Pluralismus moralischer Normen eine Dimension des Ethischen zum Ausdruck bringt, die in den evolutiven Konzepten der ethischen Anpassung an je hohere gesellschaftliche Synthesen unterschatzt wird. Insofern gehort dieses Buch in den Zusammenhang einer philosophisch-soziologischen Grundlagenforschung, wie sie seit Max Scheler und Helmuth Plessner als Philosophische Anthropologie durchgefuhrt wurde und welche Arnold Gehlen - von den Elementarbestanden der menschlichen Existenz bis zur Analyse der modernen Malerei - mit so viel Sachhaltigkeit weiterverfolgt hat.

Ignorance of one’s privileges and prejudices is an epistemic problem. While the sources of ignorance of privilege and prejudice are increasingly understood, less clarity exists about how to remedy ignorance. In fact, the various causes of ignorance can seem so powerful, various, and mutually reinforcing that studying the epistemology of ignorance can inspire pessimism about combatting socially constructed ignorance. I argue that this pessimism is unwarranted. The testimony of members of oppressed groups can often help members of privileged groups overcome (...) their ignorance. This paper argues that a particular type of speaker’s trust—hopeful trust—can motivate hearers to become cognizant of their privilege and prejudice. I argue that hopeful trust is a powerful way of eliciting trust-responsiveness that can be an effective mechanism for challenging privilege and prejudice. To make this case, I draw on case studies of online attempts to challenge ignorance. While the problems of testimonial injustice, defensi... (shrink)

Traditionally, there has been a clear distinction between classical systems and quantum systems, particularly in the mathematical theories used to describe them. In our recent work on macroscopic quantum systems, this distinction has become blurred, making a unified mathematical formulation desirable, so as to show up both the similarities and the fundamental differences between quantum and classical systems. This paper serves this purpose, with explicit formulations and a number of examples in the form of superconducting circuit systems. We introduce three (...) classes of physical systems with finite degrees of freedom: classical, standard quantum, and mixed quantum, and present a unified Hilbert space treatment of all three types of system. We consider the classical/quantum divide and the relationship between standard quantum and mixed quantum systems, illustrating the latter with a derivation of a superselection rule in superconducting systems.

Imagine that you and a duplicate of yourself are lying unconscious, next to each other, about to undergo a complete step-by-step exchange of bits of your bodies. It certainly seems that at no stage in this exchange of bits will you have thereby switched places with your duplicate. Yet it also seems that the end-result, with all the bits exchanged, will be essentially that of the two of you having switched places. Where will you awaken? I claim that one and (...) the same person possesses both bodies, occupies both places and will experience both awakenings, just as a person whose brain has been bisected must at once experience both of the unconnected fields of awareness, even though each of these will falsely appear to him as the entirety of his experience. I also claim that the more usual apparent boundaries of persons are as illusory as those in brain bisection; personal identity remains unchanged through any variation or multiplication of body or mind. In all conscious life there is only one person - I - whose existence depends merely on the presence of a quality that is inherent in all experience - its quality of being mine, the simple immediacy of it for whatever is having experience. One powerful argument for this is statistical: on the ordinary view of personhood it is an incredible coincidence for you (though not for others) that out of 200,000,000 sperm cells the very one required on each occasion for your future existence was first to the egg in each of the begettings of yourself and all your ancestors. The only view that does not make your existence incredible, and that is not therefore (from your perspective) an incredible view, is that any conscious being would necessarily have been you anyway. It is a consequence that self-interest should extend to all conscious organisms. (shrink)

Background: Few robust autism-specific outcome assessments have been developed specifically for use by teachers in special schools. The Assessment of Barriers to Learning in Education – Autism is a newly developed teacher assessment to identify and show progress in barriers to learning for pupils on the autism spectrum with coexisting intellectual disabilities. Aims: This study aimed to conduct a preliminary validity and reliability evaluation of the ABLE-Autism. Methods and procedures: Forty-eight autistic pupils attending special schools were assessed using the ABLE-Autism. (...) Multi-level modelling was used to evaluate test-retest reliability, internal consistency and convergent validity with the Teacher Autism Progress Scale. Outcomes and results: Results showed excellent test-retest reliability and internal consistency. A large effect size suggested that the ABLE-Autism is strongly correlated with the Teacher Autism Progress Scale. Teacher feedback was positive and suggested that the ABLE-Autism is easily understood by teachers, relevant to autistic pupils in special schools, and adequately covers the skills and behaviours that teachers believe are important to assess for these pupils. Conclusions and implications: Although further validation is recommended, the preliminary evaluation of the ABLE-Autism suggests that it is a useful and has the potential to be an effective outcome assessment for autistic pupils in special schools.
