O uso de dispositivos móveis e tecnologia touchscreen em atividades de geometriaMeier, Melissa January 2017 (has links)
O presente trabalho buscou investigar as contribuições da utilização de tecnologias touchscreen para o desenvolvimento do pensamento matemático. Mais especificamente, propôs uma investigação de singularidades no desenvolvimento dos hábitos do pensamento em atividades de Modelagem Geométrica implementadas a partir do uso da tecnologia touchscreen. No que se refere ao desenvolvimento de hábitos do pensamento, propostos por Paul Goldenberg, é entendido como uma ação que contribui diretamente para o desenvolvimento do pensamento matemático. A escolha de trabalhar com Modelagem Geométrica é explorada neste trabalho com a finalidade de possibilitar aos sujeitos envolvidos o estudo de fenômenos reais a partir do uso de ferramentas matemáticas. Quanto à interação touchscreen, nos baseamos na teoria da Cognição Corporificada que parte do princípio de que corpo e mente estão diretamente relacionados, ou seja, no gesto com a mão os estudantes tornam evidentes as suas intenções e pensamentos. Para realização da pesquisa, a metodologia escolhida foi o estudo de casos múltiplos (dois), mas com apenas uma unidade de análise. Configura um estudo exploratório, em virtude da escassez de estudos na área por tratar-se da integração de uma nova tecnologia ao ensino Como suporte tecnológico, a escolha pelo Sketchometry, software de geometria dinâmica disponível para smartphones, se justifica, visto que este possui um importante destaque no desenvolvimento da proposta de pesquisa, uma vez que, através do seu uso, é possível que os sujeitos elaborem e construam modelos geométricos de forma corporificada (interação touchscreen), o que é uma ação necessária para a compreensão do fenômeno investigado. Ao final da tese, mostramos que, no uso da tecnologia touchscreen, é possível identificar singularidades no desenvolvimento do pensamento do sujeito. Notou-se que a singularidade no desenvolvimento do pensamento está no início da implementação de um modelo geométrico. O aluno segue um caminho guiado por movimentos espontâneos e, desta forma, estabelece a construção e funcionamento de seu modelo. / The present work has aimed to investigate the contributions of the use of touchscreen technologies for the development of mathematical thinking. More specifically, it has proposed an investigation of singularities in the development of habits of thought in Geometric Modeling activities implemented through the use of touchscreen technology. With regard to the development of habits of thought, proposed by Paul Goldenberg, it is understood as an action that contributes directly to the development of mathematical thinking. The choice of working with Geometric Modeling has been explored in this work with the purpose of enabling the subjects involved to study real phenomena that can be investigated, assimilated and better understood from the use of mathematical tools. As for the touchscreen interaction, the work was based on the theory of Embodied Cognition which assumes that body and mind are directly related, which means that, students make evident their intentions and thoughts in gesture with the hand. The methodology chosen to carry out the research was the study of multiple cases (two), but with only one unit of analysis. The study has benn configured as an exploratory one, due to the scarcity of studies in the area, since it is the integration of a new technology in teaching As technological support, the choice of Sketchometry, dynamic geometry software available for smartphones, has been justified, because it has an important emphasis in the development of the research proposal, since, through its use, it is possible for the individuals to elaborate and construct geometric models of an embodied form (touchscreen interaction), which is a necessary action for the understanding of the investigated phenomenon. At the end of the thesis, it has been shown that it is possible to identify singularities in the development of the subject's thinking in the use of touchscreen technology. It has been noted that the uniqueness in the development of thought is at the beginning of the implementation of a geometric model. The student follows a path guided by spontaneous movements and establishes the construction and functioning of his/her model.

Comprender: propuesta de pivotesAlonso, Santiago 10 April 2018 (has links)
How do we understand? A pivot proposalThe basic question is what it is needed to understand. The proposal is that understanding requires pivots, a useful word to integrate findings in different areas. In that sense, a pivot can be understood as a mental model. It can also be the body, an idea based on embodied cognition. But more fundamentally, our biology and brain are the central pivots for understanding. Therefore, this essay can be seen as a brief travel through three different subjects: Mental Models, Embodied Cognition and Cognitive Neuroscience, all of which are necessary to understand how a person understands. / La pregunta básica es qué se necesita para comprender. La propuesta es que comprender necesita pivotes, término utilizado para integrar hallazgos en varias áreas. De tal manera, un pivote puede ser entendido como un modelo mental. Un pivote también es el cuerpo, idea que surge del concepto de cognición corporizada. Pero tal vez más fundamental, la biología y el cerebro son los pivotes esenciales para comprender. Así, el ensayo se puede ver como un recorrido breve de tres materias: modelos mentales, cognición corporizada y neurociencias cognitivas; todas necesarias para entender cómo comprende una persona

The Reading of Rotated Text - An Embodied AccountJanuary 2013 (has links)
abstract: Individuals engaged in perceptual tasks often use their bodies to lighten the cognitive load, that is, they replace internal (mental) processing with external (body-based) processing. The present investigation explores how the body is used in the task of reading rotated text. The experimental design allowed the participants to exhibit spontaneous behavior and choose what strategies to use in order to efficiently complete the task. The results demonstrate that the use of external strategies can benefit performance by offloading internal processing. / Dissertation/Thesis / M.S. Psychology 2013

Neuromuscular Control Contributes to Incidental Learning: Head Orientation During Visual Statistical LearningJanuary 2013 (has links)
abstract: Incidental learning of sequential information occurs in visual, auditory and tactile domains. It occurs throughout our lifetime and even in nonhuman species. It is likely to be one of the most important foundations for the development of normal learning. To date, there is no agreement as to how incidental learning occurs. The goal of the present set of experiments is to determine if visual sequential information is learned in terms of abstract rules or stimulus-specific details. Two experiments test the extent to which interaction with the stimuli can influence the information that is encoded by the learner. The results of both experiments support the claim that stimulus and domain specific details directly shape what is learned, through a process of tuning the neuromuscular systems involved in the interaction between the learner and the materials. / Dissertation/Thesis / M.A. Psychology 2013

Efeitos da metáfora da verticalidade e do foco regulatório motivacional do consumidor sobre as avaliações de preços / Effects of the metaphor of verticality and the consumer\'s regulatory focus on price evaluationsMarconi Freitas da Costa 25 October 2017 (has links)
As pessoas costumam fazer rotineiramente associações entre o afeto com as posições verticais, nas quais os objetos que estão no alto, muitas vezes, são considerados bons e o que estão em baixo são considerados ruins. O uso da metáfora, geralmente inconsciente, pode afetar a motivação do indivíduo para fazer avaliações dos preços dos produtos. O foco regulatório motivacional do indivíduo pode apresentar características que contribuam para restaurar a motivação, porque está dividido em um foco em promoção, que visa aproveitar oportunidades e se aproximar de ganhos e em um foco em prevenção que busca manter a vigilância para evitar resultados negativos e se afastar de perdas. O principal objetivo desta pesquisa foi analisar os efeitos da metáfora da verticalidade sobre a forma que os indivíduos efetuam as avaliações de preços, tendo o foco regulatório como moderador dessa relação. Foram elaboradas sete hipóteses, testadas com o uso de experimentos. A amostra total dos experimentos, contendo um estudo piloto e três estudos que avaliaram o modelo teórico proposto, foi de 522 participantes. Os dados foram analisados por meio da ANOVA twoway e da macro PROCESS de Hayes (Modelo 8, 2013). Os resultados mostram que o grupo de tratamento com os indivíduos que se consideram fisicamente alto e com foco em prevenção fizeram avaliações dentro do proposto para este estudo, quando comparados aos indivíduos que se consideram fisicamente baixo e foco em promoção. O primeiro grupo de tratamento mencionado atribuiu os menores preços aos produtos, exigiu descontos maiores para se deslocarem para outra loja em busca de um produto, consideraram o preço praticado por uma empresa mais injusto e, por fim, tiveram o melhor desempenho na avaliação de preço para conseguir um bom negócio. A principal contribuição desta tese é de que os indivíduos estão expostos diariamente a mudanças na autoestima por causa de simulações mentais da verticalidade, em que o corpo influencia os pensamentos desses indivíduos para tomada de decisão em relação a preços, e que o foco regulatório é capaz de atenuar tais efeitos. / People routinely make associations between affection and vertical positions, in which objects that is in up positiion are often considered good and those that is in down position are considered bad. The use of the metaphor, usually unconscious, can affect the individual\'s motivation to make product price assessments. The motivational regulatory focus of the individual can present characteristics that contribute to restore motivation, because it is divided into a focus on promotion, which seeks to seize opportunities and approach gains and a focus on prevention that seeks to maintain vigilance to avoid negative results and to avoid losses. The main goal of this research was to analyze the effects of the metaphor of verticality on the form that the individuals make the price evaluations, having the regulatory focus as moderator of this relation. Seven hypotheses were elaborated, tested with the use of experiments. The total sample of the experiments, containing a pilot study and three studies that evaluated the proposed theoretical model, was 522 participants. The data were analyzed through two way ANOVA and Hayes macro PROCESS (Model 8, 2013). The results show that the treatment group with those individuals who consider themselves to be physically high and focused on prevention made evaluations within the proposed for this study when compared to individuals who consider themselves physically low and focused on promotion. The first treatment group mentioned attributed the lowest prices to the products, demanded larger discounts to move to another store in search of a product, considered the most unfair price practiced by the company and, lastly, had the best performance in price evaluation to get a good deal. The main contribution of this thesis is that individuals are exposed daily to changes in self-esteem because of mental simulations of verticality, in which the body influences the thoughts of these individuals for decision-making in relation to prices, and that the regulatory focus is capable to mitigate such effects.

Embodied Cognition and Deception : The Influence of Emotional Congruence in Detecting LiesMäättä, Jessica January 2012 (has links)
The influence of facial mimicry and emotional congruence on emotional information processing has previously only been studied in isolation. In the current study their influence on the ability to detect deception will be investigated. In order to recognize the emotional states of others one mimics their emotional facial expression, and being in a congruent emotional state as a person or an emotional message enables faster processing of emotional information. Can emotional congruence between the receiver’s emotional state and a message told affect participants’ ability to detect deception when judging whether a person at a video recording is telling the truth or not? How does emotional congruence affect participants’ speed and confidence when making these judgments? The results showed that participants reported higher confidence but slower response times when making an accurate judgment in the congruent scenario, when compared to the incongruent scenario, but did not perform better than what could be expected by chance in detecting deception. Consequently, emotional congruence had an impact, not on participants’ performance in detecting deception, but only on their meta-cognitive evaluations of their judgments, but confidence rating did not seem to be an indicator of accuracy. In future research the design can be used in order to investigate other potential aspects, such as emotional empathy and other types of emotional congruence, and their influence on the ability to detect deception.

Towards navigation without sensory inputs: modelling Hesslow?s simulation hypothesis in artificial cognitive agentsMontebelli, Alberto January 2004 (has links)
In the recent years a growing interest in Cognitive Science has been directed to the cognitive role of the agent's ability to predict the consequences of their actions, without actual engagement with their environment. The creation of an experimental model for Hesslow's simulation hypothesis, based on the use of a simulated adaptive agent and the methods of evolutionary robotics within the general perspective of radical connectionism, is reported in this dissertation. A hierarchical architecture consisting of a mixture of (recurrent) experts is investigated in order to test its ability to produce an 'inner world', functional stand-in for the agent's interactions with its environment. Such a mock world is expected to be rich enough to sustain 'blind navigation', which means navigation based solely on the agent's own internal predictions. The results exhibit the system's vivid internal dynamics, its critical sensitivity to a high number of parameters and, finally, a discrepancy with the declared goal of blind navigation. However, given the dynamical complexity of the system, further analysis and testing appear necessary.

Notions of Embodiment in Cognitive ScienceSvensson, Henrik January 2001 (has links)
Cognitive science has traditionally viewed the mind as essentially disembodied, that is, the nature of mind and cognition is neither affected by the ¡Èsystem¡É it is implemented in nor affected by the environment that the system is situated in. But since the mid-1980s a new approach emerged in artificial intelligence that emphasized the importance of embodiment and situatedness and since then terms like embodied cognition, embodied intelligence have become more and more apparent in discussions of cognition. As embodied cognition has increased in interest so have the notions of embodiment and situatedness and they are not always compatible. This report has found that there are, at least, four notions of embodiment in the discussions of embodied cognition: software embodiment, physical embodiment, biological embodiment and human(oid) embodiment.

Kroppsspråkets betydelse för empowerment : En litteraturstudie / The importance of body language in empowerment : A literature reviewShah, Ali January 2017 (has links)
Introduktion: Kunskapen om kroppsspråk i kombination med vetenskaplig psykologi har resulterat i ett flertal koncept vilka menar att kroppsspråket inte enbart är reflekterande för interna erfarenheter utan kan oberoende producera och förändra individers tankar, känslor och beteenden. Syfte: Syftet med litteraturstudien är att sammanställa studier som utvärderar vilken inverkan modifierade kroppspositioner har på empowerment. Metod: Inom databaserna PubMed, Psychological Science, Google Scholar, Scopus utfördes ett strukturerat sökande med parametrarna ”embodied cognition” och ”power posing” med kriteriet för interventionsstudier. Resultat: Sökandet och urvalet resulterade i 9 artiklar med varierade utfallsmått. Studierna visar att ett modifierat expansivt kroppsspråk har en positiv inverkan på smärttolerans, självförtroende, självbild, attityder, tankar, upplevelser av makt, emotioner samt praktiskt handlande och beslutstagande. Konklusion: Att modifiera kroppsspråket är en relativt enkel intervention som kräver minimalt med resurser för att utveckla faktorer relaterade till empowerment. Detta kan i kombination med den fysioterapeutiska kompetensen resultera i enkla och eventuellt effektiva interventionsformer. Det förekommer ett behov av fortsatt studerande för att bekräfta aktuell kunskap samt inventioner och diskussioner för att utvärdera implikationer inom den fysioterapeutiska verksamheten.

Teaching Academic Writing for Engineering Students: An Embodied, Rhetorical ApproachJanuary 2020 (has links)
abstract: This dissertation details an action research study designed to teach engineering students enrolled in a First Year Composition course understand and learn to use effective conventions of written communication. Over the course of one semester, students participated in an intervention that included embodied and constructive pedagogical practices within a rhetorical framework. The theoretical perspectives include Martha Kolln’s rhetorical grammar framework, embodied cognition, and Chi’s ICAP hypothesis. The study was conducted using an explanatory multi-methodological approach. The majority of students demonstrated that in their post-intervention writing samples, their ability to use effective conventions had improved. Over the course of the study, students’ attitudes about writing improved as did their self-efficacy about their writing ability. / Dissertation/Thesis / Doctoral Dissertation Educational Leadership and Policy Studies 2020
