Noise in behavior is often viewed as a nuisance: while the mind aims to take the best possible action, it is let down by unreliability in the sensory and response systems. How researchers study cognition reflects this viewpoint – averaging over trials and participants to discover the deterministic relationships between experimental manipulations and their behavioral consequences, with noise represented as additive, often Gaussian, and independent. Yet a careful look at behavioral noise reveals rich structure that defies easy explanation. First, both (...) perceptual and preferential judgments show that sensory and response noise may potentially only play minor roles, with most noise arising in the cognitive computations. Second, the functional form of the noise is both non-Gaussian and non-independent, with the distribution of noise being better characterized as heavy-tailed and as having substantial long-range autocorrelations. It is possible that this structure results from brains that are, for some reason, bedeviled by a fundamental design flaw, albeit one with intriguingly distinctive characteristics. Alternatively, noise might not be a bug but a feature: indeed, we suggest that noise is fundamental to how cognition works. Specifically, we propose that the brain approximates probabilistic inference with a local sampling algorithm, one that uses randomness to drive its exploration of alternative hypotheses. Reframing cognition in this way explains the rich structure of noise and leads to a surprising conclusion: that noise is not a symptom of cognitive malfunction but plays a central role in underpinning human intelligence.

The definitions of disease proffered by philosophers and medical actors typically require that a state of ill health be linked to some known bodily dysfunction before it is classified as a disease. I argue that such definitions of disease are not fully implementable in current medical discourse and practice. Adhering to the definitions would require that medical actors keep close track of the current state of knowledge on the causes and mechanisms of particular illnesses. Yet, unaddressed problems in medical terminology (...) can make this difficult to do. I show that unrecognized misuse of “heterogeneous,” “biomarker,” and other important health terms—which I call index terms—can misrepresent the current empirical evidence on illness pathophysiology, such that unvalidated illness constructs become mistaken for diseases. Thus, implementing common definitions of disease would require closing this “loophole” in medical discourse. I offer a simple rule that, if followed, could help do just that. (shrink)

Este artigo tem por objetivo relatar a experiência com o Projeto de educação filosófica denominado Ética e Educação para o Pensar a partir da Literatura Infantil, abordando a história da sua criação, algumas referências teóricas e metodológicas, a estrutura do projeto e o desenvolvimento através de parceria entre o Instituto Sadia, Fundação Sidónio Muralha, Instituto de Filosofia e Educação para o Pensar e seis secretarias de educação. O foco do projeto é a educação ética através da comunidade de investigação, enfatizando (...) a abordagem dialógica dos valores, procurando trabalhar na direção da autonomia moral e cognitiva das crianças. O projeto foi desenvolvido com professores e alunos da Educação Infantil e Ensino Fundamental I. No final do artigo são apresentadas algumas produções dos alunos desenvolvidas como parte do projeto e depoimentos dos professores sobre o mesmo. (shrink)

Ivancovsky et al. explore the relationship between curiosity and creativity, by suggesting they align through novelty-seeking mechanisms. We argue that a general mechanism linking both capacities together is question-asking: Curiosity drives question-asking that leads to creative problem solving. Yet, current findings from our lab suggest that question complexity relates to creativity, but not necessarily to curiosity, warranting further investigation.

Recently, Congress has focused on reforms to address pharmacy benefit managers’ (PBMs) role in high drug prices for patients. Congress must not excessively restrict PBMs’ ability to negotiate with manufacturers; alternatively, reforms could be paired with other policies that address the high prices of brand-name drugs.

This note examines the significance of Gylippus at Aen. 12.271–83 and argues that Virgil's narrative is an epitaphic gesture alluding to Nicander of Colophon, Anth. Pal. 7.435 and other epigrams from Anth. Pal. 7. Virgil's bilingual reader would participate in the Hellenistic Ergänzungsspiel and supplement further meaning to this otherwise generic scene.

Como un aspecto central del necropoder, se encuentra en lo que Michel Foucault denominó ontología política, ontología del presente, ontología histórica, ontología de uno mismo. La propuesta de esta obra es la ontología política del presente, la cual permite al necropoder redimensionar los que se convertirán en hechos históricos en sus alcances en el presente, saber qué es la actualidad implica reconocer que algún acercamiento del pasado se convirtió en un hecho histórico por sus efectos en el presente.

The legacy of apartheid spatial planning can still be seen in the dynamics of spaces in South Africa today. The elite (according to research is racialised and mostly white people) lives in well-located city areas, close to economic activity and rule social life that defines cities as stated in 2016 by the Socio Economic Rights Institute of South Africa (SERI). Alternatively, mostly black South Africans are confined to urban margins in densified and poorly serviced areas, with low rates of home (...) ownership. The effects of these policies extend beyond the urban nature, as spaces on the margin by design tend to have fewer opportunities for education compared to urban areas, and there are spatial limits to black business ownership. This article seeks to discuss a case study on a church’s use of space during coronavirus disease 2019 (COVID-19), to show an inclusionary spatial dynamic that may be used in South African spaces. Firstly, it presents an overview of the unequal spatial dynamics in South Africa, particularly Cape Town, and dynamics during COVID-19. Secondly, it provides a historical overview of the Church of the Nazarene and its foundational beliefs. Moreover, it discusses a case study of renewed spatial dynamic in church using the Church of the Nazarene in Khayelitsha. Furthermore, the case study will be used to show the innovative way they reached their community during this time. The final part will discuss how this inclusive spatial dynamic reveals an innovative dynamic in the concept of the missional church, one that goes beyond the going out contextually, but allowing the outside in as well. Contribution: This article discusses the new spatial dynamic of the missional church which inspires inclusivity. The article uses literature around space, COVID-19, mission studies and church history. Furthermore, a semi-structured interview with a church leader at the Church of the Nazarene in Khayelitsha is used for a contextual case study. (shrink)
