1. Overconfidence is usually understood as being more confident than reality justifies (Harvey, 1997; Moore & Healy, 2008; Pompian, 2006), which leads individuals to overestimate their performance...

Research on escalation of commitment has predominantly been studied in the context of a single decision without consideration for the psychological consequences of escalating. This study sought to examine a) the extent to which people escalate their commitment to a failing course of action in a sequential decision-making task, b) confidence and anger as psychological consequences of escalation of commitment, and c) the reciprocal relationship between escalation of commitment and confidence and anger. Participants were 110 undergraduate students who completed a (...) series of investment decisions regarding a failing endeavor. Results revealed that although a high proportion of individuals escalate through all decisions, the extent to which they escalated decreased with each decision as they were less willing to invest money in the project. Furthermore, as participants escalated, confidence in one’s decision decreased and anger increased. Lastly, the analyses revealed that the relationship between escalation and confidence is reciprocal. Escalation was negatively associated with confidence, and confidence predicted escalation in the subsequent decision. These results highlight the importance of considering both the determinants and psychological consequences of escalation of commitment. (shrink)

Habituation is defined as a decline in responding to a repeated stimulus. After more than eighty years of research, there is an enduring consensus among researchers on the existence of 9-10 behavioral regularities or parameters of habituation. There is no similar agreement, however, on the best approach to explain these facts. In this paper, we demonstrate that the Sometimes Opponent Processes (SOP) model of stimulus processing accurately describes all of these regularities. This model was proposed by Allan Wagner as a (...) quantitative elaboration of Priming Theory, which states that the processing of a stimulus, and therefore its capacity to provoke its response, depends inversely on the degree to which the stimulus is pre-represented in short-term memory. Using computer simulations, we show that all the facts involving within-session effects or short-term habituation might be the result of priming from recent presentations of the stimulus (self-generated priming). The characteristics involving between-sessions effects or long-term habituation would result from the retrieval of the representation of the stimulus from memory by the associated context (associatively-generated priming).

Apresento e desenvolvo neste artigo o problema da prova sortuda, analisando duas soluções para ele presentes na literatura. A primeira delas consistira em alegar que mostrar que o predicado está contido no sujeito não basta como demonstração da verdade de uma proposição, sendo preciso que se prove ainda que a noção relativa ao sujeito é logicamente consistente. A segunda repousaria em uma hierarquização modal, por assim dizer, dos pre- dicados integrantes de uma noção individual. Após exibir as razões que me (...) levam a rejeitar essas duas soluções, apresento os traços fundamentais de uma interpretação que me parece resolver o problema de maneira satisfatória. Minha posição envolve conceder ao Princípio da Razão Suficiente um papel central na compreensão do que significa, para Leibniz, provar que um determinado predicado está contido na noção relativa a um certo indivíduo.

Reiteradamente, ao longo de sua obra, Heidegger referiu-se ao opúsculo Sobre a essência da verdade, cuja primeira elaboração data de 1930. Chega a dizer, em entrevista ao L’Express , ser esse trabalho a "dobradiça" entre Heidegger I e Heidegger II, inseparáveis um do outro. A questão da história é nele abordada na sua relação com a verdade do ser, mais exatamente, com a idéia de que a continuidade dos eventos que concerne a essa verdade está ontologicamente ligada a uma recusa (...) original do ser a uma inteligibilidade plena ou definitiva. Dessa recusa original decorre a liberdade e, simultaneamente, a possibilidade do erro, a errância; decorre, igualmente, a possibilidade de completo desnorteamento. Tomando essas teses como ponto de partida, é possível afastar da concepção heideggeriana de história quaisquer traços de processualismo ou teleologia, e, sobretudo, reconciliá-la com uma idéia simultaneamente geral e "concreta" de alteridade. É o que aqui se pretende.Over and over along his works Heidegger has mentioned the opuscule On the Essence of Truth, whose first elaboration dates from 1930. In an interview to L'Express he even comes to say about this work that it is a "hinge" between Heidegger I and Heidegger II, inseparable from each other. The text deals with the question of history in its reference to the truth of being, more precisely, to the idea that the continuity of events related to this truth is ontologically tied to an original refusal of being to a full or conclusive intelligibility. What is brought out of this original refusal is freedom but, at the same time, the possibility of error, errancy; it also follows the possibility of complete disorientation. Taking these thesis as a starting point, it is possible to move away from the heideggerian conception of history any traces of processualism or teleology and, above all, to reconcile it with an idea both broad and "concrete" of alterity. That's what we intended to do here. (shrink)

Resumo: Discuto, no presente artigo, a concepção leibniziana da mente, mostrando que as percepções e as sensações podem ser compreendidas como constituindo uma série contínua, mas que as apercepções forçosamente introduzem uma descontinuidade no sistema, o que torna essa concepção incompatível com o princípio da continuidade, igualmente assumido por Leibniz.Abstract: I discuss in this article the Leibnizian conception of the mind, showing that perceptions and sensations can be understood as constituting a continuous series, but that apperceptions forcibly introduce a discontinuity (...) into the system, which renders this conception incompatible with the principle of continuity, also assumed by Leibniz.

To explore social media use in New Zealand, a sample of 1001 adults aged 18 and over were surveyed in November 2021. Participants were asked about the frequency of their use of different social media platforms (text message included). This report describes how often each of the nine social media sites and apps covered in the survey are used individually on a daily basis. Differences based on key demographics, i.e., age and gender, are tested for statistical significance, and findings summarised.

A gestão da Covid no Brasil está entre as piores do mundo, com número de óbitos inaceitavelmente alto. É inclusive estranho que esses resultados não tenham sido capazes de disparar entre os brasileiros nenhuma mobilização social mais decisiva. Não obstante o reconhecimento da importância do debate mais estritamente político, o objetivo deste artigo é ensaiar uma reflexão fenomenológica sobre a respiração, tendo Heidegger como referência principal. A Covid é afinal uma doença respiratória, que nos convida – ou deveria convidar – (...) a pensar sobre a respiração sob perspectivas históricas, ontológicas e existenciais. São dois os temas a discutir: nossa empobrecida relação com o respirar, e a dificuldade de, mesmo diante de mais de 600 mil mortes direta ou indiretamente causadas no Brasil por asfixia – e mais de 5 milhões no mundo –, encontrarmos caminho para discutir o assunto com mais profundidade.

Edgar Morin prône une refonte profonde de l'éducation, centrée sur sa mission essentielle telle que l'envisageait Rousseau : enseigner à vivre. Il s'agit de permettre à chaque individu d'acquérir une autonomie, de se prémunir contre l'erreur et l'illusion, de pratiquer la compréhension d'autrui, d'affronter les incertitudes, en somme de le préparer à affronter les problèmes du “vivre”.

De acordo com o Princípio da Continuidade, adotado por Leibniz, toda mudança ocorre gradativamente, havendo sempre um grau intermediário entre dois estados quaisquer. Esse princípio parece ser, contudo, incompatível com a doutrina leibniziana acerca da natureza da autoconsciência, uma vez que Leibniz, ao menos prima facie, sustenta haver uma diferença de natureza – e não apenas de grau – entre percepções inconscientes e conscientes, fornecendo esta distinção a base para a diferenciação ontológica das mônadas entre puras enteléquias, almas e espíritos. (...) O objetivo principal do presente texto é sugerir uma forma de compatibilização do Princípio da Continuidade com a doutrina leibniziana da autoconsciência. (shrink)

Imaginary worlds are extremely successful. The most popular fictions produced in the last few decades contain such a fictional world. They can be found in all fictional media, from novels (e.g., Lord of The Rings and Harry Potter) to films (e.g., Star Wars and Avatar), video games (e.g., The Legend of Zelda and Final Fantasy), graphic novels (e.g., One Piece and Naruto), and TV series (e.g., Star Trek and Game of Thrones), and they date as far back as ancient literature (...) (e.g., the Cyclops Islands in The Odyssey, 850 BCE). Why such a success? Why so much attention devoted to non-existent worlds? In this paper, we propose that imaginary worlds co-opt our preferences for exploration, which have evolved in humans and nonhuman animals alike, to propel individuals toward new environments and new sources of reward. Humans would find imaginary worlds very attractive for the very same reasons, and under the same circumstances, as they are lured by unfamiliar environments in real life. After reviewing research on exploratory preferences in behavioral ecology, environmental esthetics, neuroscience, and evolutionary and developmental psychology, we focus on the sources of their variability across time and space, which we argue can account for the variability of the cultural preference for imaginary worlds. This hypothesis can, therefore, explain the way imaginary worlds evolved culturally, their shape and content, their recent striking success, and their distribution across time and populations.

Trata-se da difícil questão do sentido em que, a partir de Heidegger, pode ser pensada uma superação da metafísica. O pano de fundo é a atualidade e a onipresença do seu acabamento técnico. A preocupação central é o problema do possível modo de ser - ou de sobreviver - de um pensamento que, imerso nessa onipresença, seja, ainda assim, capaz de interrogá-la. Questões como a do salto e da reviravolta revelam a espécie de contorcionismo envolvido nessa noção de superação, levando (...) a refletir, entre outras coisas, sobre a relação desse pensamento com a sua história. O desfecho é a identificação de um campo de preocupações no qual um pensamento posto diante da própria possibilidade de aniquilação coloca a si mesmo o problema hermenêutico de uma lúcida práxis pensante.We deal with a difficult question: the sense in which, after Heidegger, one can think of an overcoming of metaphysics. The background is the currency and omnipresence of its technical ending. Mainly focused is the problem of the possible way of being - or surviving - of a thought that, immersed in this omnipresence, is still able to inquire it. Questions such as that of the leap and the reversal show the kind of contortionism attached to this notion of overcoming. Among other issues, they call for a reflection on the relation of this thought with its history. The outcome is the identification of a field of matters which makes appear, for a thought facing the possibility of its own annihilation, the hermeneutic problem of a lucid thinking praxis. (shrink)

Free logic - i.e., logic free of existential presuppositions in general and with respect to singular terms in particular- began to come into its own as a field of research in the 1950s. As is the case with so many developments in Western philosophy, its roots can be traced back to ancient Greek philo sophy. It is only during the last fifty years, however, that it has become well established as a branch of modern logic. The name of Karel Lambert (...) is most closely connected with this development: he gave it its name and its profile as a well defined field of research. After a development of fifty years, it is time to look back and take stock while at the same time scanning for new perspectives. This is the purpose of the papers collected in this volume. The first paper is written by Karel Lambert himself who also comments on all the papers of the other authors. In an introductory essay we give a survey of the present status of and new directions in free logic. (shrink)

"Qui augmente sa connaissance augmente son ignorance" disait Friedrich Schlegel. "Je vis de plus en plus avec la conscience et le sentiment de la présence de l'inconnu dans le connu, de l'énigme dans le banal, du mystère en toute chose et, notamment, des avancées d'une nouvelle ignorance dans chaque avancée de la connaissance" nous dit Edgar Morin. Ainsi a-t-il entrepris ici de patrouiller dans les territoires nouveaux de la connaissance, où se révèle un trio inséparable : connaissance, ignorance, mystère. (...) À ses yeux, le mystère ne dévalue nullement la connaissance qui y conduit. Il nous rend conscient des puissances occultes qui nous commandent et nous possèdent, tels des Daimon intérieurs et extérieurs à nous. Mais, surtout, il stimule et fortifie le sentiment poétique de l'existence."--Page 4 of cover. (shrink)

In Sein und Zeit , Heidegger claims that (1) das Man is an 'existential' i.e. a necessary feature of Dasein's Being; and (2) Dasein need not always exist in the mode of the Man -self, but can also be eigentlich , which I translate as 'self-owningly'. These apparently contradictory statements have prompted a debate between Hubert Dreyfus, who recommends abandoning (2), and Frederick Olafson, who favors jettisoning (1). I offer an interpretation of the structure of Dasein's Being compatible with both (...) (1) and (2), thus resolving the Dreyfus-Olafson debate. Central to this resolution is the distinction between das Man and the Man -self. Das Man is one of three existential 'horizons', or fields of possibilities; the other two horizons are the world and death. At any time, Dasein encounters entities in one of two basic modes: either by 'expressly seizing' possibilities of the horizon, or by occluding these possibilities. These modes are 'existenti ell ', i.e. features of Dasein's Being that are possible, but not essential. Self-ownership and the Man -self are the two basic existentiell modes of being oneself, i.e. projecting everyday possibilities of oneself appropriated from the horizon of das Man . What differentiates these two modes is the stance one takes to the possibility of death, the existential horizon of being oneself. (shrink)

In the second edition of Hermann Cohen’s Kant’s Theory of Experience, he abandons the interpretation of Kant’s Anticipations of Perception that he gave in the first edition, in favourof a radically different one. On his early interpretation, the Anticipations is largely of psychological interest for its influence on, and continuing significance for, physiological psychology and psychophysics. But on his mature interpretation, it defends the superiority of a dynamic conception of nature over a mechanical conception. Further, on his early interpretation, Cohen (...) thought the Anticipations was not a central part of Kant’s critical theory of knowledge. But on his mature interpretation, he thinks it is absolutely central to that project. What is more, Cohen seems to have revised his interpretation in a relatively short period of time, in 1880-1. This paper argues that Cohen’s change in views about Kant’s Anticipations is explained by his reception of Leibniz in the very early 1880s, and specifically Cohen’s reception of Leibniz’s arguments against Descartes’ view that extension is the essence of matter.

En el presente escrito examinamos brevemente con intenciones comparativas la historiología y algunos de sus fundamentos en Michel Foucault, Giorgio Agamben y Peter Sloterdijk; posteriormente analizamos de manera somera la posición política que del mismo modo subyace dichas concepciones de la historia; por último construimos de manera esquemática y general una historiografía a partir de la obra temprana de Sigmund Freud, con base en la experiencia que sus casos revelaban para producir nuevas concepciones de algunos elementos importantes para la conformación (...) de una historiologia y que, como veremos, produce una peculiar e inédita concepción de la historia, a pesar de que, de inicio, no era tal la intención de la producción teórica del psicoanálisis primitivo.

In early 2020, in-person data collection dramatically slowed or was completely halted across the world as many labs were forced to close due to the COVID-19 pandemic. Developmental researchers who assess looking time were forced to re-think their methods of data collection. While a variety of remote or online platforms are available for gathering behavioral data outside of the typical lab setting, few are specifically designed for collecting and processing looking time data in infants and young children. To address these (...) challenges, our lab developed several novel approaches for continuing data collection and coding for a remotely administered audiovisual looking time protocol. First, we detail a comprehensive approach for successfully administering the Multisensory Attention Assessment Protocol, developed by our lab to assess multisensory attention skills. The MAAP is administered from a distance by using Zoom, Gorilla Experiment Builder, an internet connection, and a home computer. This new data collection approach has the advantage that participants can be tested in their homes. We discuss challenges and successes in implementing our approach for remote testing and data collection during an ongoing longitudinal project. Second, we detail an approach for estimating gaze direction and duration collected remotely from webcam recordings using a post processing toolkit and demonstrate its effectiveness and precision. However, because OpenFace derives gaze estimates without translating them to an external frame of reference, we developed a machine learning approach to overcome this limitation. Thus, third, we trained a ML algorithm [] to classify gaze estimates from OpenFace with respect to areas of interest on the participant's screen. We then demonstrate reliability between this approach and traditional coding approaches. The combination of OpenFace and ML will provide a method to automate the coding of looking time for data collected remotely. Finally, we outline a series of best practices for developmental researchers conducting remote data collection for looking time studies. (shrink)
