The Conjunction Fallacy from a Safety Culture Perspective - An Experimental Study

Nordgren, Johan Alexander January 2016 (has links)
Heuristic estimates of probabilities may be an obstacle to decision making within High Reliability Organizations. Accident reports have found that two from each other separate phenomenon, Blame Culture and Type 1 processing constitutes a particularily serious threat to decision making. The present study (N = 70) investigated if a perceived risk of negative feedback and cognitive load would lead to more heuristic estimates on the Conjunction Fallacy. Three experiment conditions were included in the study: Negative feedback, cognitive load and control. The results were non-significant for both negative feedback and cognitive load. Furthermore, the estimated negative affect was higher when violations to the Conjunction Rule was made. Previous studies showing that high scores on the Cognitive Reflection Test (CRT) indicate less sensitivity to conjunction fallacies, were replicated. The present study concluded that the CRT may be a strong predictor of the Conjunction Fallacy.

La contribution de la stéréoscopie à la constance de forme

Beaulieu, Julien 11 1900 (has links)
Le but de cette étude est de vérifier l'apport de la stéréoscopie dans le phénomène de la constance de forme. La méthode utilisée consiste à mesurer la performance de différents participants (temps de réponse et de taux d'erreurs) à une tâche de prospection visuelle. Quatre groupes de participants ont effectué la tâche. Le premier groupe a été exposé à une présentation stéréoscopique des stimuli, le deuxième groupe à une présentation des stimuli en stéréoscopie inversée (la disparité binoculaire était inversée), le troisième groupe à des stimuli comprenant une information de texture, mais sans stéréoscopie et le quatrième groupe à des stimuli bi-dimensionnels, sans texture. Une interaction entre les effets de rotation (points de vue familiers vs. points de vue non familiers) et le type d'information de profondeur disponible (stéréoscopie, stéréoscopie inversée, texture ou ombrage) a été mise en évidence, le coût de rotation étant plus faible au sein du groupe exposé à une présentation en stéréoscopie inversée. Ces résultats appuient l'implication de représentations tridimensionnelles dans le traitement de l'information visuelle. / This study was conducted to evaluate the contribution of stereopsis to the shape constancy phenomenon. Four groups of eight participants each were asked to perform a visual exploration task. The first group was exposed to a stereoscopic stimulation, the second group was exposed to a reversed stereoscopic stimulation, the third group was exposed to a monocular stimulation with textures and shadow and the fourth group was exposed to a monocular stimulation with shadow only. Response times and error rates were used to measure participant's performance. Results show an interaction between rotation effects (familiar viewpoints vs. non-familiar viewpoints) and available depth cues (stereopsis, reversed stereopsis, textures and shadow, shadow only). The rotation cost was smaller in the group exposed to a reversed stereoscopic stimulation. These results are congruent with the use of tridimensional representations underlying visual processing.

Codificação incidental da ordem serial na memória de trabalho visuoespacial: evidências baseadas em uma tarefa de detecção da mudança / Incidental encoding of serial order in visuospatial working memory: evidence based on a change detection task

Santana, Jeanny Joana Rodrigues Alves de 03 September 2010 (has links)
A memória para a ordem dos eventos em uma sequência está relacionada com muitos domínios cognitivos, como direcionar o comportamento a um objetivo, reconhecer uma ação e prever eventos do ambiente. A codificação da ordem serial tem sido, portanto, um tema polêmico a ser explicado pelos modelos de memória de trabalho visuoespacial. Neste estudo investigamos a codificação incidental da ordem serial de eventos em tarefas de reconhecimento de sequências, nas quais a dimensão relevante para a resposta poderia ser a aparência visual, a localização espacial ou a conjunção visuoespacial dos eventos. A tarefa exigia que os participantes (n=60) detectassem uma mudança em um dos estímulos da sequência e ignorassem mudanças na dimensão irrelevante: a ordem na qual os eventos eram apresentados. De maneira geral, o desempenho foi mais prejudicado nas sequências em que a ordem dos itens mudava. A comparação das três condições de memória (aparência visual, localização espacial e conjunção visuoespacial) revelou que houve melhor desempenho na tarefa espacial. Nesta condição, ocorreu uma interação entre os fatores mudança na dimensão relevante (localização espacial) e mudança na dimensão irrelevante (ordem serial). Estes resultados revelam que a ordem foi codificada de forma incidental com as informações relevantes para a tarefa. A diferença do efeito da mudança da dimensão irrelevante para os três tipos de sequências sugere que a ordem foi codificada em um estágio inicial do processamento de informações e, por isto, incluída na comparação de características, gerando diferentes padrões de respostas conforme a modalidade do estímulo. A interação entre localização e ordem serial indica que a informação espacial foi registrada de maneira integrada à ordem dos eventos na sequência, em uma representação espaço-temporal unitária. Supõe-se que um mecanismo de manutenção da informação espacial tenha operado recitando os eventos na ordem em que foram apresentados na sequência. Considera-se, também, a possibilidade de a apresentação sequencial dos estímulos ter gerado uma representação visuoespacial baseada em uma organização temporal das informações. Neste caso, é provável que um mecanismo de integração de informações tenha operado para realizar a interface entre uma estrutura temporal previamente armazenada na memória de longo prazo e o conteúdo da memória de trabalho. Estes achados sugerem a existência de um sistema responsável pela conjunção de informações de diferentes dimensões e integração de conteúdos da memória de trabalho e memória de longo prazo. As evidências obtidas neste estudo têm implicações em diferentes áreas do conhecimento. Na perspectiva da psicologia cognitiva experimental são discutidos os modelos atuais de memória de trabalho. No âmbito da psicologia cognitiva aplicada são fornecidos subsídios teóricos para o desenvolvimento de ferramentas diagnósticas para caracterização de déficits de aprendizagem e lesões neurológicas relacionados com o processamento de sequências de informações visuoespaciais. Além disso, é possível estabelecer uma relação entre os processos de memória e os mecanismos de organização do comportamento em contextos clínicos. / The memory for the events order in a sequence is related to many cognitive domains, such as managing behavior to a goal, to recognize an action and anticipate events in the real world. The encoding of serial order has been a controversial topic to be explained by the models of visuospatial working memory. We investigated the incidental encoding of events serial order in recognition tasks sequences, in which a relevant dimension to the response could be the visual appearance, the spatial location or visuospatial conjunction of events. The task required that participants (n = 60) to detect a change in a sequence of stimuli and ignore changes in irrelevant dimension: the order in which events were presented. In general, performance was more impaired in the sequences where the order of items changed. The comparison of the three memory conditions (visual appearance, spatial location and visuospatial conjunction) revealed that there was better performance in spatial task. In this condition, there was an interaction between change in the relevant dimension (spatial location) and change in the irrelevant dimension (serial order). These results show that the order was codified indirectly with relevant information to the task. The difference in the effect of changing the dimension irrelevant to the three types of sequences suggests that the order was codified in an early stage of information processing and, therefore, included in feature comparison, generating different patterns of responses depending on the modality of the stimulus. The interaction between location and serial order indicates that the spatial information was registered in an integrated manner to the order of events following in a unitary space-time representation. It is assumed that a mechanism for maintenance of spatial information has operated reciting the events in the order they were presented in sequence. It is considered also the possibility that the sequential presentation of stimuli have generated a visuospatial representation based on information temporal organization. In this case, it is likely that a mechanism of information integration has operated to achieve the interface between a temporal structure previously stored in long-term memory and the contents of working memory. These findings suggest the existence of a system responsible for the combination of information from different dimensions and integration of working memory contents and long-term memory. Data obtained in this study have implications in different areas of knowledge. In view of experimental cognitive psychology current models of working memory are discussed. Within the cognitive psychology applied theoretical support are provided for the development of diagnostic tools for characterizing learning deficits and neurological injuries related to the processing of visuospatial information sequences. Furthermore, it is possible to establish a relationship between memory processes and the mechanisms of organization of behavior in clinical settings.

Kvantitativní a kvalitativní rozbor spojek ve vybrané dětské literatuře / Quantitative and qualitative analysis of the conjuctions in the selected children's literature

Rybáková, Jana January 2018 (has links)
This thesis describe distribution of conjunction in the first seven books "Diary of a Wimpy kid". It compare and analyse those conjunctions with its usage in school lessons (through one part of a Czech national corpus - SCHOLA2010) and with text from students (through a corpus SKRIPT2012). I compare also the situation with conjunctions distribution in the textbook for 5th grade students named More vlast je v Evropě. It also research how and which one of multiword conjunction are in these texts used. It also shows, which conjunctions are used like a first member of the sentence. This thesis may analyse, which conjunctions hears, reads and uses a fictitious 5th grade student. It should be connected with a school. This thesis ignore a language situation in the family and medial communication. Analysed books may enrich students vocabulary, because it contents huge number of multiword conjunction. The most used conjunctions in books and students text are "a", "že" and "ale". The textbook contains huge number of "a" and "i".

An Essay on Thomas Reid´s Philosophy of Science

Callergård, Robert January 2006 (has links)
Though generally recognized as a formative force in his philosophy, Thomas Reid’s Newtonianism and his philosophy of science has not received due attention among scholars. My aim is to inaugurate a detailed survey. In ch. 1 it is shown that Reid demarcates physics as against metaphysics and theology, making his brand of Newtonianism different from first generation moral and religious Newtonianism. In ch. 2 it is argued that "Newtonian" is not an apt label on Reid’s call for a Science of the human mind. Neither his practice within the field, nor his methodological views, make lawlike connections the central kind of truth to be discovered. Ch. 3 is devoted to Reid’s account of the 1st and 2nd of Newton’s Regulae Philosophandi, and an ensuing notion of explanation which approaches the deductive-nomological model. It is shown that Reid’s account is very much his own, though presented as an explication of Newton’s intentions. Reid’s dismissive view towards simplicity as a guide in scientific reasoning leans on Bacon’s theory of idols and Reid’s theory of first principles of common sense. Ch 4 concerns hypotheses in connection with Newton’s phrase Hypotheses non fingo. It is argued that Reid does not mind speculation about unobservable or theoretical entities, and that his objections to particular ether theories are scientific rather than principled. Nonetheless, since Reid does not explain the difference between powerful conjecture and established truth, his notion of scientific reasoning remains elusive. Ch 5 concerns Reid’s views on the concept and ontology of forces of attraction. It is argued that Reid takes forces to be physical entities open for empirical enquiry, and that forces are neither active, nor efficient. Finally, Reid’s view of metaphysics is considered, and further differences with early Newtonians emphasised.

Konjunkcija meninio ir administracinio stiliaus tekstuose / Connectives in literary and administrative texts

Daukintytė, Renata 24 September 2008 (has links)
Konjunkcija – loginiai prasminiai ryšiai tarp dviejų sakinių, realizuojami formaliomis sakinių siejimo priemonėmis, išreiškiančiomis tam tikrus santykius. Konjunkcijos raiškos priemonių gretinimui pasirinkti dviejų skirtingų funkcinių stilių – meninio ir administracinio – tekstai. Konjunkcija skirstytina į du tipus: tipiškąją ir modalinę. Tipiškąja konjunkcija reiškiami santykiai yra grynieji, jais nenusakomas joks vertinimas ar santykis su tekstu. Pagal tai, kokias funkcijas tekste atlieka loginės semantinės (prasminės) sakinių siejimo priemonės, skiriami keturi tipiškosios konjunkcijos potipiai: sudėjimo, priežasties, priešinamoji ir laiko konjunkcija. Modalinės konjunkcijos siejimo priemonės ne tik susieja sakinius kokiu nors santykiu, bet taip pat nusako ir tam tikrą adresanto požiūrį į sakomą dalyką, turi subjektyvumo atspalvį; ją realizuojančios siejimo priemonės gali išreikšti abejojimą, įsitikinimą, pabrėžimą ar reikšti informacijos šaltinį. Tirtų konjunkcijos atvejų analizė leidžia daryti tokias išvadas: 1) Gausiausia tirtuose tekstuose – sudėjimo konjunkcija (45%). Dažniausias sudėjimo santykis – turinio papildymas – meninio stiliaus tekste reiškiamas sudedamuoju jungtuku ir, administracinio stiliaus tekste – jungtuku tačiau. 2) Pridūrimo konjunkcija būdinga tik meninio stiliaus tekstams, nes atlieka ekspresinę funkciją. 3) Administracinio stiliaus tekste labai dažnas iliustruojamasis santykis, realizuotas įterpiniu pavyzdžiui. Tai lemia analizuoto teksto... [toliau žr. visą tekstą] / A conjunction is a logical semantic link between two sentences, realized with the formal devices for connecting sentences, and expressing certain relations. Two different styles of texts were chosen for the comparison of the devices used to express a conjunction, which are literary texts and administrative texts. Conjunctions are divided into two types: typical and modal. A typical conjunction expressing relation are pure, and with them no judgement or link with the text is defined. There are four sub-types of typical conjunctions according to the functions the logical semantical devices for connecting sentences perform in the text, which are additive, causal, adversative and temporal conjunctions. The linking device for a modal conjuntion do not only link sentences by a relation, but also define a certain point of view by the addresser towards something that is said, and has a hint of subjectivity; the connecting tools realizing it can express doubt, certainty, emphasis or stand for an informational source. The analysis of the cases of the conjuntions studied allow one to make the following conclusions: 1. The most conjunctions found in the texts analysed were additive conjuntions (45 %). The most common building relationship – extension – in an literary text is expressed by using the building conjuntion ir (“and”), and in administrative texts with the conjunction tačiau (“however”). 2. Enhancement conjunctions are characteristic only for literary texts, because they... [to full text]

Žánrově podmíněné variace kohezních prostředků v japonštině / Genre-Conditioned Variation of Cohesive Devices in Japanese

Černáčková, Júlia January 2017 (has links)
e Abstract (in English): The aim of the present thesis is to investigate the differences in cohesive devices use in selected Japanese texts of different genes. The English conception of cohesion (based on Halliday and Hasan's "Cohesion in English") is applied to Japanese with several slight modifications and the following devices and their sub-types are examined: reference, substitution, ellipsis, conjunction and lexical cohesion. Using three texts of different genres- book review, newspaper article and a fictional narrative- the assumption of genre-conditioned variation of cohesive devices employment is scrutinized and the distinctions and similitudes are described. The first, general theory part of the thesis presents the basic concepts related to cohesion. In the second part, both English and Japanese perspectives on cohesion are presented. Subsequently, the English (Halliday and Hasan's) concept is evaluated as a more pertinent one and applied in the Japanese textual environment. Subsequent parts of the paper present research questions as well as supporting arguments to the examined underlying assumption and provide an overview of methodology applied in analysis of the selected texts. In the final part, the results concerning cohesion articulation in various genres in Japanese obtained from the analysed...

Polysémie et polyfonctionnalité du mot "si" : propriétés syntaxiques, sémantiques et pragmatiques en français préclassique / Polysemy and polyfunctionality of the word "si" (if) : syntactic, semantic and pragmatic properties in pre classical French

Dhiabi, Tijani 26 January 2019 (has links)
S’inscrivant dans le cadre des recherches portant sur les changements linguistiques, cette thèse a une double visée : d’une part, élaborer une description de tous les emplois du mot si en français préclassique et, d’autre part, signaler les formes en usages à l’époque préclassique qui ont disparu au bénéfice de nouvelles formes devenues en usage en français moderne. La première partie constitue un état des connaissances sur le terme si depuis les remarqueurs de la langue préclassique jusqu’aux recherches contemporaines. Les deuxième et troisième parties sont consacrées à l’étude des emplois adverbiaux et conjonctionnels du mot si tel qu’ils se manifestaient dans la langue préclassique. Cette étude, s’appuyant sur des exemples empruntés à des œuvres littéraires du début, du milieu et de la fin de la période allant de 1550 jusqu’à 1650, se situe dans la lignée des théoriciens des approches de l’analyse du discours dont les postulats permettent de rendre compte des différents types d’analyse syntaxiques, sémantiques, énonciatives et pragmatiques. Ainsi, le si préclassique, s’il partage des propriétés communes avec ses emplois modernes, s’en singularise toutefois sur quelques points dans la mesure où aucun emploi de la langue préclassique ne correspond parfaitement à son vis-à-vis de la langue actuelle. Malgré cette divergence, les emplois préclassiques du mot si tendent à s’écarter de ses usages de l’époque médiévale et à se rapprocher progressivement du système de la langue d’aujourd’hui. / This thesis is a part of researches that deals with linguistic change has two main objectives. Firstly, to elaborate a full description of all the usages of the French word “si” (if) in pre-classical French. Secondly, to indicate the forms its uses in the pre-classical era, which is no longer used where they give way to other forms and other usages in French modern language. The first part deals with the history of the term “si” (if), dating from the pre-classic era to our contemporary age, however the second and the third examines the adverbial and conjunctional uses of this word as it appears in the pre-classical language. This study, which relies on examples taken from old literary works written during the beginning, the middle and the end of this era from 1550 to 1650, is on line with the theorists of Discourse analysis approaches whose postulates make it possible to account for the different types of syntactic, semantic, enunciative and pragmatic analysis. Then, the pre-classic “si” (if), if he shares common properties with its modern usage, there it is worth noting that no use of the pre-classical language corresponds perfectly to its current language. Furthermore, the modern “si” (if) is closer in its usage to modern than the medieval one. Despite this divergence, the pre-classical uses of the word “si” (if) tend to deviate from its uses of the medieval period and move progressively towards the system of the language of today.
