In that sense, it is clear that Cognition is a great ally to Management, as the later deals with people and is very interested in how they behave, think, and make decisions. However, even though Cognition shows great promise as a field, there are still many topics to be explored and learned in this fairly new area. Kemp & Tenembaum (2008) tried to a model graph-structure problem in which, given a dataset, the best underlying structure and form would emerge from said dataset by using bayesian probabilistic inferences. This work is very interesting because it addresses a key cognition problem: learning. According to the authors, analogous insights and discoveries, understanding the relationships of elements and how they are organized, play a very important part in cognitive development. That is, this are very basic phenomena that allow learning. Human beings minds do not function as computer that uses bayesian probabilistic inferences. People seem to think differently. Thus, we present a cognitively inspired method, KittyCat, based on FARG computer models (like Copycat and Numbo), to solve the proposed problem of discovery the underlying structural-form of a dataset.

Als Ergebnis der vorliegenden Arbeit wurde ein nützliches Hilfsmittel auf der Basis der kognitiven Herangehensweise zur Verbesserung der Effizienz der Managemententscheidungen für die Gussausschussverringerung und Qualitätsverbesserung in den Gießereien entwickelt.

Man kann das Werkzeug täglich im Betrieb benutzen, um die strategischen und operativen Entscheidungen rasch und ohne Durchführung der kostspieligen und komplizierten Versuche zu treffen. Auf diese Weise können Kosten und Zeit eingespart werden.

The ability to solve problems creatively has been crucial for the adaptation and survival of humans throughout history. In many real–life situations, cognitive processes are not isolated. Humans are social, they communicate and form groups to solve daily problems and make decisions. Therefore, the final output of cognitive processes can come from multi–brains in groups rather than an individual one. This multi–brain output can be largely different from the output that an individual person produces in isolation. As a result, it is essential to include team–level processes in cognitive models to make a more accurate description of real– world cognitive processes in general and problem solving in particular. This research aims to answer the general question of how working in a team affects creative problem solving. For doing that, first, we propose a computational model for multi-agent creative problem solving. Then, we show how the model can be used to study the factors that are involved in creativity in teams and potentially will suggest answers to questions such as, ‘how team size is related to creativity’.

To be able to make accurate predictions and adapt, we sometimes need to adjust our understanding of the world, yet what incentivizes expansion of our mental world models remains poorly understood. The aim of this study was to investigate what motivates people to update their world models – here referred to as the ontological model structure, and how updating is related to uncertainty. The study is of experimental design and uses a digital game divided into two conditions (ambiguous and unambiguous) that vary the expectations for the game’s causal structure. The goal of the game was to gain points by accurately predicting on what food item a fly will land. To make accurate predictions, the participant should adjust their cognitive model when encountering new information. Data from 84 participants was collected online, using Prolific.co. It was hypothesized that initial ambiguity would affect the likelihood of information seeking by increasing the frequency of prediction errors and would result in a faster switch to an optimal cognitive model. The study found that participants in the more ambiguous condition sought information earlier, gained more prediction errors and changed to an optimal model faster than participants in the less ambiguous condition. However, both participant groups seemed equally as equipped to change models as a result of prediction errors. This might indicate that despite similar support for an initial model, it is the prediction errors and our recent history that affects our tendency to adjust our cognitive models. / För att kunna göra korrekta prediktioner och anpassa oss behöver vi ibland justera vår förståelse av världen, vad som motiverar en revidering av våra mentala modeller är dock fortfarande oklart. Studiens syfte var att undersöka vad som motiverar människor att uppdatera sina modeller – benämnd här som den ontologiska modellstrukturen, och hur uppdateringen är relaterad till osäkerhet. Studien är av experimentell design och använder ett digitalt spel uppdelat i två betingelser (tvetydig och entydig), som varierar förväntningarna på spelets ontologiska struktur. Spelets mål var att samla poäng genom att korrekt predicera på vilken matvara en fluga kommer att landa. För att kunna göra korrekta prediktioner bör deltagaren justera sin kognitiva modell när ny information fås. Data från 84 deltagare samlades in online, med hjälp av Prolific.co. Det antogs att den initiala tvetydigheten skulle påverka sannolikheten för informationssökning genom att öka frekvensen av prediktionsfel och att det skulle resultera i en snabbare övergång till en optimal kognitiv modell. Studien fann att deltagare i den mer tvetydiga betingelsen sökte information tidigare, fick fler prediktionsfel och ändrade till en optimal modell snabbare än deltagare i den mindre tvetydiga betingelsen. Däremot verkade båda deltagargrupperna lika väl utrustade att byta modell till följd av prediktionsfel. Det kan tyda på att trots liknande stöd för en initialmodell är det prediktionsfel och vår närhistoria som påverkar vår tendens att justera våra kognitiva modeller.

This study aimed to examine the relationship between romantic self-concept (self-concept in the realm of love) and satisfaction in one’s love life. Drawing from a population of mainly college students, overall self-concept was measured using the “Six-Factor Self-Concept Scale for Adults” (Stake, 1994). Additionally, the assessment was augmented by incorporating several more curated questions specifically designed to measure one’s romantic self-concept. Moreover, their satisfaction in love life was measured using Neto’s (2005) “Satisfaction with Love Life Scale”. Lastly “The Relationship Assessment Scale” (Hendrick, 1988) was used to measure couple satisfaction for those who were not single. The guiding hypothesis proposed that those with a higher (more positive) romantic self-concept will experience greater satisfaction levels within their love lives. This research highlights the intricate dynamics and influences shaping the link between individuals' self-perceptions and their experiences in romance.

Depuis une vingtaine d’années, le modèle cognitif basé sur les interprétations (Groupe de recherche sur la cognition dans le trouble obsessionnel compulsif [OCCWG], 1997, 2001, 2003, 2005) représente le modèle psychologique de l’étiologie et du maintien du TOC le plus étudié au plan empirique. Cependant, peu de recherches ont porté sur les deux postulats importants du modèle touchant respectivement le développement des croyances liées à l’obsessionnalité et la contribution des états affectifs au maintien des interprétations et des croyances (réactivité cognitive). L’objectif de cette thèse est de contribuer à la validation empirique de ces postulats. Fondé sur un devis corrélationnel dans un échantillon de participants mixte (participants troubles obsessionnels-compulsifs et participants non cliniques), le premier article étudie les liens entre les expériences de l’enfance et la présence de croyances obsessionnelles chez l’adulte. Deux modèles alternatifs sont comparés qui représentent d’une part un lien spécifique, et d’autre part un lien non spécifique entre les expériences de l’enfance et les croyances obsessionnelles adultes. Les résultats suggèrent la présence à la fois de relations spécifiques et non spécifiques entre les expériences de l’enfance et les croyances adultes. Les expériences de l’enfance et les domaines de croyance obsessionnels qui montrent des liens spécifiques sont ceux relatifs à la responsabilité, à la perception du danger, et au perfectionnisme. En contrepartie, les expériences de l’enfance relatives à la perception de danger et dans une moindre mesure la sociotropie, apparaissent étroitement liés à la plupart des domaines de croyances adultes (intolérance à l’incertitude, surestimation du danger, importance et contrôle des pensées). Dans la seconde étude, nous nous intéressons à la mesure et l’analyse longitudinales de la réactivité cognitive telle qu’elle s’exprime dans l’environnement naturel de huit participants troubles obsessionnels-compulsifs de type ruminateur. Par le biais de huit protocoles à cas uniques intensifs, l’analyse de contingence entre les scores quotidiens d’humeur (4 états émotionnels cotés par participant) et d’interprétations (une interprétation idiographique des intrusions par participant) permet d’établir une mesure de l’importance de la réactivité cognitive chez chaque participant. Ces résultats sont ensuite analysés du point de vue des postulats principaux de deux modèles spécifiques de la réactivité cognitive (modèle de l’Infusion de l’affect [Forgas, 2008] et modèle de l’Humeur comme intrant [Meeten & Davey, 2011]. Ainsi, les analyses intra-individuelles répétées trans-comportements) et interindividuelles (trans-participants) permettent d’illustrer le rôle proximal déterminant des stratégies de traitement de l’information (traitement systématique; traitement superficiel; traitement altéré) employées par les participants. En résumé, les résultats obtenus dans ces deux études fournissent des données utiles à la poursuite de la validation du modèle des interprétations du TOC. Dans la première étude, l’identification de liens spécifiques entre les EE et les croyances obsessionnelles soutient la séquence étiologique postulée, alors que l’identification de liens non spécifiques suggère que d’autres trajectoires étiologiques peuvent être pertinentes. Dans la seconde étude, l’analyse longitudinale et naturaliste des covariations humeur – interprétations se révèle d’abord féconde à identifier les phénomènes de réactivité cognitive postulés dans le modèle des interprétations. Ensuite, en conformité aux modèles intégrés de la réactivité cognitive, l’analyse des liens entre cette réactivité et les stratégies privilégiées de neutralisation des participants permet d’identifier le rôle clé des différentes stratégies de traitement de l’information dans la réactivité cognitive. / Over the past twenty years, the «appraisal model» of obsessive-compulsive disorder (OCD) (Obsessive Compulsive Cognition Working Group, 1997, 2001, 2003, and 2005) has drawn most of the empirical research on the psychological etiology and maintenance of the disorder. Nevertheless, only a few studies addressed two important postulates of the model, which is the development of beliefs associated with OCD, and the contribution of affective states to the maintenance of appraisals and beliefs (p. ex., cognitive reactivity). The current thesis aims to contribute to the empirical validation of these postulates. Based on a retrospective correlational design in a mixed (OCD and normal) sample, the first article aims to explore the links between childhood experiences (CEs) and adult OCD related beliefs. Two alternative etiological models are compared emphasizing either a rather specific association between different CEs and beliefs; or conversely, a broad non-specific association between CEs and different OCD related beliefs. Results support both the existence of specific and non-specific associations between CEs and beliefs. CEs and OCD related beliefs that showed specific links were those CEs that showed specific links to OCD related beliefs were those related to the concepts of Responsibility (R-E and OBQ-R), Threat perception (TP-E et OBQ-T), and Perfectionism (SO-E et OBQ-P). On the other hand, CEs emphasizing Threat perception (TP-E) and Sociotropy (SOC-E) related experiences also showed significant links with most OCD related beliefs (Intolerance of uncertainty [OBQ-U], Overestimation of threat [OBQ-T], Importance and Control of thoughts [OBQ-I et OBQ-C]). The aim of the second article is to assess and analyze cognitive reactivity in an OCD sample (rumination subtype) through a longitudinal naturalistic design (eight intensive single-case designs). In a first step, the contingency analysis between daily mood-states scores (4 mood-states in each participant) and daily thought appraisals (one idiosyncratically defined thought appraisal in each participant) allows for the assessment of the magnitude and rate of cognitive reactivity in each participant. On the basis of integrative models of cognitive reactivity (Affect Infusion Model, and Mood as input Hypothesis) further repeated intra-individual analyses (across subjects) and inter-individual analyses (between subjects) illustrate the critical proximal role of different processing strategies used by the participants. In summary, both studies provide results that contribute to further the validation of the appraisal model of OCD. In the first study, the identification of specific links between CEs and OCD related beliefs in adults supports the postulated etiological sequence; while the identification of non-specific links suggest that other etiological paths may be relevant In the second study, the longitudinal investigation of covariations between mood-states and appraisals of thoughts allows to reveal the expected cognitive reactivity processes. Such processes are further supported with reference to integrated models of cognitive reactivity that emphasize the critical role of different processing strategies in their expression.

En nous inspirant du modèle cognitif de production humaine d'Anderson, nous considérons, dans cette thèse, comme des processus universels intégrant le système de production humaine, une grande partie des stratégies d'apprentissage présentées dans différents classements. Dans cette perspective, nous avons examiné la différence stratégique entre les apprenants, comme le soutiennent d'aucuns, ainsi que la modification que pourrait produire une formation à l'emploi des stratégies d'apprentissage dans le répertoire des stratégies des apprenants. Nous montrons que le développement des compétences en langues implique inévitablement la mise en place de procédures générales de résolution de problèmes régies par des stratégies universelles. Nous nous intéressons particulièrement à la nature universelle des stratégies d'apprentissage. Dans cette perspective nous avons effectué une étude empirique visant à analyser les stratégies d'apprentissage de deux groupes d'apprenants adultes iraniens du français -dont l'un a reçu une formation à l'emploi des stratégies d'apprentissage. Les résultats de nos analyses de leurs productions orales et écrites confirment le fondement théorique de notre recherche. En effet, l'enseignement des stratégies d'apprentissage que proposent certains ne modifie pas l'utilisation des stratégies d'apprentissage ayant trait aux processus mentaux régissant les productions humaines chez l'apprenant adulte et ce sont les savoirs déclaratifs des apprenants qui différencient leurs productions langagières. / Based on the cognitive model of human production of Anderson, we considered in this thesis, a large part of the learning strategies presented in the various classifications as universal human process system production. In this context we examined the strategic difference of learners, as some argue, and the modification that could produce training in the use of learning strategies in the repertoire of strategies learners.We have shown that the development of language skills is based on the activation of general procedures for solving problems governed by universal strategies.We are particularly interested in this thesis, in the universal nature of learning strategies. In this perspective we conducted an empirical study which aims at analyzing learning strategies of two groups of Iranian adult learners, one of which received training in the use of learning strategies learning. The results of our analysis of their oral and written productions have confirmed the theoretical basis of our research. Indeed, the teaching of learning strategies, that offer some, do not change the use of learning strategies and their language productions depend on their declarative knowledge. .Keywords: cognitive model of human production, learning strategies, training in the use of learning strategies, declarative knowledge, Iranian adult learners.
