31	Cognitive and Behavioral Model Ensembles for Autonomous Virtual Characters Whiting, Jeffrey S. 08 June 2007 (has links) (PDF) Cognitive and behavioral models have become popular methods to create autonomous self-animating characters. Creating these models presents the following challenges: (1) Creating a cognitive or behavioral model is a time intensive and complex process that must be done by an expert programmer (2) The models are created to solve a specific problem in a given environment and because of their specific nature cannot be easily reused. Combining existing models together would allow an animator, without the need of a programmer, to create new characters in less time and would be able to leverage each model's strengths to increase the character's performance, and to create new behaviors and animations. This thesis provides a framework that can aggregate together existing behavioral and cognitive models into an ensemble. An animator only has to rate how appropriately a character performed and through machine learning the system is able to determine how the character should act given the current situation. Empirical results from multiple case studies validate the approach taken. cognitive modeling behavioral modeling ensembles machine learning ensembles cognitive model ensembles behavioral model ensembles computer animation behavioral animation character animation synthetic characters behavioral modeling machine learning autonomous agents AI-based animation computer games Computer Sciences
32	Developing a cognitive model to motivate school principals in the Mpumalanga Province Mashaba, Sebakane William 05 1900 (has links) The main purpose of the study was to develop a cognitive model to motivate principals in the Mpumalanga Province, particularly in the Bohlabela District. That was done firstly by identifying and explaining main factors affecting motivation of principals, and later developed a cognitive model of motivation from such factors. The study used the interpretative approach, particularly constructive-interpretative paradigm to collect and analyse principals’ subjective, but accurate accounts of their views, feelings, perceptions and experiences regarding the factors they had found motivating or de-motivating. A case study method was used as the main design method and was implemented through purposive sampling to identify information-rich participants. Semi-structured interviews were employed as the main data collection technique and the data obtained were confirmed, corroborated and augmented by observational field notes and documents analysis, particularly during data analysis. The researcher segmented and coded the data inductively into two main themes, which served as the main empirical research findings. Such findings indicated that motivation is influenced by both cognitive and systemic factors. It is recommended that setting difficult, but specific intrinsic outcomes and consciously employing cognitive abilities to pursue them, might improve motivation. Furthermore, full personal responsibility should be taken regarding the attainment of such intrinsic outcomes. / Educational Studies / D. Ed.

33	憂鬱與日常生活的心境一致想法：日程紀錄研究 / Depression and mood congruent thoughts in everyday life：A diary study 黃柏僩 Unknown Date (has links) 本文試圖將日程紀錄法的研究典範應用於憂鬱的心理病理研究，聚焦於兩研究問題：（一）探討個體的憂鬱症狀與其日常生活正/負向情感傾向的關係，以及該正/負向情感傾向如何影響其每日的正/負向想法；（二）根據「素質-壓力模式」的觀點，探討個體於日常生活中展現的情感傾向與認知特性，在控制住基準點的憂鬱症狀後，是否仍可顯著預測個體處於壓力狀態的憂鬱症狀。93名大學生完整參與本研究，問卷評估包括基準點的憂鬱症狀、日程紀錄期間的每日正/負向情感與正/負向想法、以及其期中考期間的憂鬱症狀。研究顯示憂鬱個體展現較低的正向情感傾向與較強的負向情感傾向，而個體的正/負向情感傾向與狀態可顯著預測其正/負向想法，且情感傾向與狀態對想法存在顯著的交互作用；另外，個體於日常生活展現的平均負向想法與正向情感傾向，在控制住基準點的症狀後，仍可顯著預測其處於壓力的憂鬱症狀。最後，我們則探討本研究對心理病理與治療的意涵。 / The authors attempted using diary method paradigm to study psychopathology of depression. The study focused on two questions: (1) explore the relationship between individuals’ depressive symptoms and their tendency of positive/ negative affect, and how the tendency of affect impact their daily positive/ negative thoughts; (2) according to the view of diathesis-stress model, explore how the affective tendency and cognitive characteristics exhibited in daily life could predict their depressive symptoms under stress after the initial symptoms are controlled. 93 participants finished all questionnaires, including initial depressive symptoms, daily positive/ negative affect, positive/ negative thoughts, and depressive symptoms under midterm examination. The results showed that depression is related to low positive affect and high negative affect. Individuals’ tendency and state of positive/ negative affect could predict their daily positive/ negative thoughts, and there exist a significant interaction effect between tendency and state to thoughts. Further, individuals’ tendency of positive affect and average negative could predict their depressive symptoms under stress after the initial symptoms are controlled. Finally, the implications for psychopathology and therapy are discussed. 憂鬱三元模式心境一致效果 Beck的認知模式差別活化假說日程紀錄法 depression tripartite model mood congruent effect Beck's cognitive model differential activation hypothesis diary method
34	Motivations for Indoor Tanning: Theoretical Models Hillhouse, Joel J., Turrisi, Rob 01 January 2016 (has links) This chapter reviews the literature applying health behavior theories to indoor tanning. Few studies have tried to fit full versions of health behavior models to indoor tanning. Theoretical models from the family of theories referred to as the reasoned action approach (e.g., theory of planned behavior, behavioral alternative model, prototype willingness model, etc.) have been most commonly used to study indoor tanning. Results indicate that these models fit indoor tanning data moderately to extremely well. Two lesser known models, problem behavior theory and the terror management health model, have also demonstrated a reasonable fit. Two other common models, the health belief model and social cognitive theory, have never been fully tested with indoor tanning. However, key constructs from these models (e.g., perceived susceptibility and threat, modeling) have been used to understand indoor tanning. Empirical research conducted represents a solid start toward developing strong, comprehensive models of indoor tanning that can guide intervention efforts. This initial work needs to be expanded by conducting longitudinal studies and by including a broader age range in studies because the majority of existing work has focused on young adults. Incorporating findings related to tanning dependency, peer group affiliation, media influences and other constructs into these foundational models will also improve our understanding and ability to develop efficacious interventions to reduce engagement in this health risk behavior. behavioral alternative model cancer research dermatology health behavior health belief model health promotion and disease prevention health psychology indoor tanning integrative model popular science in medicine and health problem behavior theory prototype theory reasoned action approach social cognitive model terror management theoretical models theory of planned behavior turrisi Community and Behavioral Health Behavior and Behavior Mechanisms Community Health and Preventive Medicine Dermatology
35	Le discours de la persuasion : une étude pragmatique et cognitive / The discourse of persuasion : a pragmatic and cognitive review Da Silva Anunciacao, Jessica 25 November 2013 (has links) Cette recherche a comme objectif d’analyser le discours persuasif dans le cadre du discours religieux. Notre travail dissèque les outils utilisés par les locuteurs pour persuader les auditeurs à l’appui d’un vaste présupposé théorique. Cette thèse s’appui sur les propositions d’étude du domaine de la rhétorique, de l’analyse du discours, de la pragmatique et de la linguistique cognitive.Nous démontrons que ces domaines si différents peuvent être complémentaires dans l’étude des techniques persuasives. Nous avons identifié et analysé certaines opérations cognitives orchestrées par le cerveau humain lors de la persuasion. Ces opérations sont identifiables grâce à des indices linguistiques spécifiques.L’ossature de cette recherche consiste à expliquer comment est structuré le discours religieux et persuasif et de quelles techniques disposent les orateurs. Grâce aux réponses à ces questions centrales, nous sommes en mesure de connaître plus profondément les astuces du discours de la persuasion qui peuvent être utiles bien au-delà du domaine de la linguistique / This research has as an objective analysis of the persuasive speech in the context of religious discourse. Our work dissects the tools used by speakers to persuade listeners to support a broad theoretical assumption. This thesis is supported on the proposed study area Rhetoric of discourse analysis, pragmatics and cognitive linguistics.We show that if these different areas can be complementary in the study of persuasive techniques. We have identified and analyzed some orchestrated by the human brain during cognitive processes of persuasion. These operations are identified by specific linguistic cues.The framework of this research is to explain how the religious structured and persuasive speeches and what techniques have speakers. With answers to these key questions, we are able to know more deeply the tricks of speech of persuasion that can be useful well beyond the field of linguistics Persuasion Rhétorique Analyse du discours Linguistique cognitive Modèle cognitive idéalisé Sémiolinguistique Intéraction Espaces mentaux Ontégration conceptuelle Acte perlocutoire Pragmatique Métaphores Empathie Enallages Persuasion Rhetoric Discourse analysis Cognitive linguistics Cognitive model idealized Semio-linguistics approach, Interaction Mental spaces Blending Perlocutionary act Pragmatic Metaphors Empathy Enallages 401.41 302.24
