The theory of visual perception that Irvin Rock develops and supports in this book with numerous original experiments, views perception as the outcome of a process of unconscious inference, problem solving, and the building of structural descriptions of the external world.

Arien Mack and Irvin Rock make the radical claim that there is no conscious perception of the visual world without attention to it.

A practical, refreshingly optimistic guide that uses centuries-old wisdom to help us better cope with the stresses of modern living. Some people bounce back in response to setbacks; others break. We often think that these responses are hardwired, but fortunately this is not the case. Stoicism offers us an alternative approach. Plumbing the wisdom of one of the most popular and successful schools of thought from ancient Rome, philosopher William B. Irvine teaches us to turn any challenge on its head. (...) The Stoic Challenge, then, is the ultimate guide to improving your quality of life through tactics developed by ancient Stoics, from Marcus Aurelius and Seneca to Epictetus. This book uniquely combines ancient Stoic insights with techniques discovered by contemporary psychological research, such as anchoring and framing. The result is a surprisingly simple strategy for dealing with life’s unpleasant and unexpected challenges—from minor setbacks like being caught in a traffic jam or having a flight cancelled to major setbacks like those experienced by physicist Stephen Hawking, who slowly lost the ability to move, and writer Jean-Dominique Bauby, who suffered from locked-in syndrome. The Stoics discovered that thinking of challenges as tests of character can dramatically alter our emotional response to them. Irvine’s updated “Stoic test strategy” teaches us how to transform life’s stumbling blocks into opportunities for becoming calmer, tougher, and more resilient. Not only can we overcome everyday obstacles—we can benefit from them, too. (shrink)

Sloman suggests that although many try to model consciousness as a unitary and abstract entity, the project is an incoherent one. This claim will be supported, but it will also be argued that current movements in consciousness research are broadly consistent with Sloman's "alternative" suggestions of how best to make progress in this area.

History was a continuous cycle driven by the gods. Societies began by being small, impoverished, and insignificant, then became great, then proud and decadent, and finally were overthrown by a different small, impoverished people, with the cycle beginning anew. Herbert's historical universe in Dune is bound within a series of ever repeating cycle. Herbert's themes about human action, fatalism versus free will, and the repetition of religious motifs across vast distances of space and time. Greek mythology and tragedy appear on (...) the very first page of Dune with the use of a single word: Atreides. Much like in the Dune series, History emerged in the ancient Greek world by combining mythology, epic narrative, and tragedy. The Golden Path is the death of the constant cycles of imperialism and the freeing of humanity from constantly repeating old mistakes. (shrink)

Artificial intelligence (AI) will drastically change the healthcare system. Radiology is one speciality that is most affected as AI algorithms are increasingly used in diagnostic imaging. AI‐enhanced health technologies will, inter alia, increase workflow efficiency, improve diagnostic accuracy, reduce healthcare‐related costs, and help alleviate medical personnel shortages in under‐resourced settings. However, the development of AI‐enhanced technologies in healthcare is fraught with legal, ethical, and human rights concerns. Currently, the use of AI in South African healthcare is not governed by sui (...) generis legislation or ethical guidance focused exclusively and specifically on AI, although various provisions and principles from law and ethics find application. This article outlines these normative principles and explains their relationship with the extant legal obligations and regulatory framework as applied to the use of AI in radiology services in South Africa. The article concludes with three key recommendations for radiology practitioners using AI in South Africa. These are the need for: vigilant monitoring of AI use in practice, reforms to the liability framework, and appropriate guidance from local regulators and the Health Professions Council of South Africa on the ethical use of AI.

Block [Block, N. . Two neural correlates of consciousness. Trends in Cognitive Science, 9, 46–52] and Snodgrass claim that a signal detection theory analysis of qualitative difference paradigms, in particular the exclusion failure paradigm, reveals cases of phenomenal consciousness without access consciousness. This claim is unwarranted on several grounds. First, partial cognitive access rather than a total lack of cognitive access can account for exclusion failure results. Second, Snodgrass’s Objective Threshold/Strategic model of perception relies on a problematic ‘enable’ approach to (...) perception that denies the possibility of intentional control of unconscious perception and any effect of following different task instructions on the presence/absence of phenomenal consciousness. Many of Block’s purported examples of phenomenal consciousness without cognitive access also rely on this problematic approach. Third, qualitative difference paradigms may index only a subset of access consciousness. Thus, qualitative difference paradigms like exclusion failure cannot be used to isolate phenomenal consciousness, any attempt to do so still faces serious methodological problems. (shrink)

Insults are part of the fabric of daily life. But why do we insult each other? Why do insults cause us such pain? Can we do anything to prevent or lessen this pain? Most importantly, how can we overcome our inclination to insult others? In A Slap in the Face, William Irvine undertakes a wide-ranging investigation of insults, their history, the role they play in social relationships, and the science behind them. He examines not just memorable zingers, such as Elizabeth (...) Bowen's description of Aldous Huxley as "The stupid person's idea of a clever person," but subtle insults as well, such as when someone insults us by reporting the insulting things others have said about us: "I never read bad reviews about myself," wrote entertainer Oscar Levant, "because my best friends invariably tell me about them." Irvine also considers the role insults play in our society: they can be used to cement relations, as when a woman playfully teases her husband, or to enforce a social hierarchy, as when a boss publicly berates an employee. He goes on to investigate the many ways society has tried to deal with insults-by adopting codes of politeness, for example, and outlawing hate speech-but concludes that the best way to deal with insults is to immunize ourselves against them: We need to transform ourselves in the manner recommended by Stoic philosophers. We should, more precisely, become insult pacifists, trying hard not to insult others and laughing off their attempts to insult us.A rousing follow-up to A Guide to the Good Life, A Slap in the Face will interest anyone who's ever delivered an insult or felt the sting of one--in other words, everyone.

A methodology is shown to evaluate the quality of the continuous improvement plans in schools of the upper medium type. For this, a rubric validated by expert judgment and Alpha de Crombach was prepared. The results obtained show the distribution of the quality level of the PMC, as well as the most recurring errors during the planning process.

Snodgrass et al.’s commentary makes explicit one of the major problems in consciousness research; that there seem to be just as many definitions of basic terms are there are people in the field. Although Snodgrass et al.’s position appears at odds with the views expressed in Irvine , many of their arguments are actually consistent with the proposed views, or else fail to engage with them as a consequence of the shifting goal posts of what basic terms mean.
