Die emotionale Valenz von Wörtern beeinflusst deren kognitive Verarbeitung. Ungeklärt ist, obwohl von zentraler Bedeutung für die Disziplinen der Psycholinguistik und der Neurowissenschaften, die Frage nach dem funktionellen Lokus von Emotionseffekten in der visuellen Wortverarbeitung. In der vorliegenden Dissertation wurde mit Hilfe von Ereignis-korrelierten Potentialen (EKPs) untersucht, ob emotionale Valenz auf lexikalischen oder auf semantischen Wortverarbeitungsstufen wirksam wird. Vorausgegangene Studien weisen auf einen post-lexikalischen Lokus von Emotionseffekten hin, wobei einige wenige heterogene Befunde von sehr frühen Emotionseffekten auch einen lexikalischen Lokus vermuten lassen. In der vorliegenden Arbeit wurden drei emotions-sensitive EKP Komponenten beobachtet, die distinkte zeitliche und räumliche Verteilungen aufwiesen, und daher verschiedene Wortverarbeitungsstufen zu reflektieren scheinen. Die Ergebnisse wurden im Rahmen von allgemeinen Annahmen aktueller Wortverarbeitungs- und semantischer Repräsentationsmodelle diskutiert. Als zentrales Ergebnis kann benannt werden, dass Emotion am stärksten semantische Wortverarbeitungsstufen beeinflusste. Hieraus wurde geschlussfolgert, dass emotionale Valenz einen Teil der Wortbedeutung darstellt. Eine Interaktion mit einem lexikalischen Faktor sowie sehr frühe Emotionseffekte deuten auf einen zusätzlichen Lokus auf lexikalischen oder sogar perzeptuellen Wortverarbeitungsstufen hin. Dies bedeutet, Emotion veränderte die visuelle Wortverarbeitung auf multiplen Stufen, dabei konnten separate emotions-sensitive EKP Komponenten, die unterschiedlichen Randbedingungen unterliegen, mit jeweils einem frühen (pre-)lexikalischen und einem späten semantischen Lokus in der Wortverarbeitung in Verbindung gesetzt werden. Die Befunde stützen Wortverarbeitungsmodelle, die zeitlich flexible und interaktive Wortverarbeitungsstufen annehmen. / Emotional valence of words influences their cognitive processing. The functional locus of emotion effects in the stream of visual word processing is still elusive, although it is an issue of great importance for the disciplines of psycholinguistics and neuroscience. In the present dissertation event-related potentials (ERPs) were applied to examine whether emotional valence influences visual word processing on either lexical or semantic processing stages. Previous studies argued for a post-lexical locus of emotion effects, whereas a lexical locus has been indicated by a few heterogeneous findings of very early emotion effects. Three emotion-related ERP components were observed that showed distinct temporal and topographic distributions, and thus seem to reflect different processing stages in word recognition. Results are discussed within a framework of common assumptions from word recognition and semantic representation models. As a main finding, emotion impacted most strongly semantic processing stages. Thus, emotional valence can be considered to be a part of the meaning of words. However, an interaction of emotion with a lexical factor and very early emotion effects argued for an additional functional locus on lexical, or even on perceptual processing stages in word recognition. In conclusion, emotion impacted visual word processing on multiple stages, whereas distinct emotion-related ERP components, that are subject to different boundary conditions, were associated each with an early (pre-)lexical locus or a late semantic locus. The findings are in line with models of visual word processing that assume time-flexible and interactive processing stages, and point out the need for integration of word recognition models with models of semantic representation.

Dans les dernières décennies, le présumé déclin de la compétence scripturale des élèves québécois a soulevé les passions. Force est d’admettre que leurs compétences sont lacunaires : tant les rapports du ministère de l’Éducation (Jalbert, 2006; Ouellet, 1984) que les études scientifiques ou gouvernementales (Bureau, 1985; Groupe DIEPE, 1995; Roberge, 1984) révèlent leur incapacité à s’approprier l’écriture. Les TIC pourraient bien faire partie de la solution : on sait pertinemment qu’elles favorisent la réussite scolaire dans certains contextes (Barayktar, 2001; Christmann & Badgett, 2003; Waxman, Lin, & Michko, 2003). Toutefois, modifient-elles le processus scriptural au point d’en faciliter l’apprentissage? Cette question constitue le cœur de l’actuel projet de recherche. Les modèles du processus d’écriture comme celui de Hayes et Flower (Flower & Hayes, 1981; Hayes, 1995; Hayes & Flower, 1980) rappellent que les TIC font partie du contexte de production; à ce titre, elles influencent autant la qualité des textes que les processus cognitifs et la motivation. Elles libèrent notamment des ressources cognitives, puisqu’elles prennent en charge certaines opérations, comme la calligraphie (Daiute, 1983). Partant, le scripteur peut se concentrer davantage sur des tâches plus complexes. Des méta-analyses (Bangert-Drowns, 1993; Goldberg, Russell, & Cook, 2003) attestent que le traitement de texte exerce un effet minime, mais statistiquement significatif sur la qualité de l’écriture. Toutefois, il est associé à des révisions en surface (Faigley & Witte, 1981; Figueredo & Varnhagen, 2006). Rares sont les projets de recherche qui explorent simultanément l’impact du traitement de texte sur plusieurs dimensions du processus scriptural; plus rares encore sont les travaux qui se sont intéressés à ce sujet depuis les années 1990. Pour pallier ce manque, cette thèse de doctorat vise à 1) mesurer l’effet des TIC sur la qualité de l’écriture; 2) décrire l’impact des TIC sur les processus cognitifs de révision et de traduction; 3) mesurer l’impact des TIC sur la motivation à écrire. Pour y arriver, nous recourons à une méthodologie mixte. D’une part, un devis de recherche quasi expérimental nous permet de comparer les scripteurs technologiques aux scripteurs traditionnels; d’autre part, une approche qualitative nous laisse accéder aux pensées et aux perceptions des utilisateurs de l’ordinateur. Les trois articles qui constituent le cœur de cette thèse rapportent les résultats relatifs à chacun des objectifs spécifiques de recherche. Dans le premier texte, nous avons mesuré les effets du traitement de texte sur la compétence scripturale. L’analyse statistique des données colligées nous a permis de dégager une amélioration des performances, strictement en orthographe d’usage. En comparaison, les élèves du groupe témoin se sont améliorés davantage en cohérence textuelle et ont mieux performé en orthographe grammaticale. Le deuxième article propose de faire la lumière sur ces résultats. Nous y étudions donc l’impact des TIC sur le processus cognitif de révision. Ce volet, basé sur une approche qualitative, recourt largement à l’observation vidéographiée. Nous y mettons d’abord en évidence le grand nombre d’erreurs commises lors des séances d’écriture technologiques; nous faisons également ressortir la sous-utilisation du vérificateur linguistique, qui pose peu de diagnostics appropriés ou qui est souvent ignoré des scripteurs. Toutefois, malgré cette sous-utilisation du traitement de texte, des entrevues de groupe font état de perceptions positives à l’égard des TIC; on leur prête des vertus certaines et elles sont jugées motivantes. Ce phénomène constitue le cœur du dernier article, au cours duquel nous tâchons de mesurer l’impact du mode d’écriture sur la motivation à écrire. Nous menons ce volet dans une perspective quantitative. La motivation des participants a été mesurée avec une échelle de motivation. L’analyse statistique des données montre que les élèves technologiques sont motivés intrinsèquement par les technologies, tandis que leurs pairs du groupe témoin sont amotivés. Lors du chapitre conclusif, nous mettons ces résultats en relation, tentant d’expliquer globalement l’impact des TIC dans le processus scriptural. Au terme de notre thèse, nous formulons des recommandations destinées aux praticiens et aux décideurs engagés dans le système éducatif. / The supposed decline of writing skills in Quebecois students’ during the last decades has raised vigorous debates. Admittedly, their competencies show deficiencies. Indeed, reports by the Ministry of Education (Jalbert, 2006; Ouellet, 1984) and research, both scientific and governmental (Bureau, 1985; Groupe DIEPE, 1995; Roberge, 1984), reveal their incapacity to appropriate the writing process. ICT might well be part of the solution : it is a well-known fact that they encourage scholastic achievement in certain contexts (Barayktar, 2001; Christmann & Badgett, 2003; Waxman, et al., 2003). However, do they modify the writing process so as to facilitate its learning? This question is at the heart of the current research project. Writing process models, such as those of Hayes and Flower (1981; 1995; 1980), remind us that ICT are a part of the Context component; as such, they influence the quality of the texts as much as cognitive processes and motivation. They unburden the cognitive process by taking on certain functions such as calligraphy (Daiute, 1983). Consequently, the writer may concentrate on more complex tasks. Meta-analyses (Bangert-Drowns, 1993; Goldberg, et al., 2003) show that the use of word processors has a small yet statistically significant effect on the quality of writing. That being said, they are mainly linked to surface changes (Faigley & Witte, 1981; Figueredo & Varnhagen, 2006). Research projects that explore the impact of word processors on the writing process and its various dimensions simultaneously are rare, even more so since the last twenty years. To satisfy this research gap, the present thesis aims at 1) measuring ICT effect upon the quality of writing; 2) describe ICT impact on the cognitive processes of translating and reviewing; 3) measure ICT impact on motivation to write. To this objective, we utilize a mixed methodology. On one hand, a quasi-experimental design allows for a comparison of technological writers to traditional writers; on the other, a qualitative approach provides access to the thoughts and perceptions of computer users. The three articles that constitute the heart of this thesis relate the results pertaining to the stated research objectives. In the first text, we measured the effects of word processing on the quality of writing. The statistical analysis of the dataset allowed us to observe an improvement in spelling, but not grammatical spelling. In comparison, students of the control group showed improvements in their texts’ logical coherence and grammatical orthography. The second article intends to shed light on these results. The impact of ICT on the cognitive processes of translating and reviewing is studied to that effect. This aspect, which is based on a qualitative approach, is largely based on video observation. First, are highlighted the many errors committed when word processing is used. Then, is underlined the poor use of spell checking tools, that oftentimes provide inappropriate diagnostics or that are simply ignored by users. However, group interviews have shown positive perceptions vis-à-vis ICT, despite their poor use. Indeed, they are considered motivating and their benefits, although recognized, do not seem to have an impact. The motivating factor is at the heart of the last article, which measures the impact of writing methods on the motivation to write. A quantitative analysis is used to that effect. The participants’ motivation was measured using a motivational scale. The statistical analysis of the dataset demonstrates that technological students are intrinsically motivated by ICT, whereas their peers of the control group are amotivated. In the concluding chapter, we put theses results in relation with one another so as to explain the impact of ICT on the writing process as a whole. Lastly, we hope to provide possible recommendations to practitioners and decision makers within the educational system.

Many adults who enter universities to continue their education are placed in developmental or basic writing classes. With the prevalence of computers on university campuses, some of these writing classes are taught in computerbased classrooms, which may cause adult learners to be apprehensive of both writing and computers. Previous research studies regarding writing and computer apprehension have examined traditional age college students, ignoring how the social context of the computer-based classroom and the computers used as tools for writing may affect adult learners' attitudes toward both writing and computers. The purpose of this descriptive study of adult developmental writers was to examine their perceptions of the effects of computers in a computer-based writing classroom, focusing on how the context of the classroom, including the social situation within the computer-based classroom, influenced their attitudes and apprehension toward both writing and computers.In order to obtain scores that indicated students' apprehension toward writing and computers, the Daly-Miller Writing Apprehension Test and the Loyd and Gressard Computer Attitude Survey were given to adult learners (n=41) at the beginning and the end of the semester to determine changes in students' apprehension. Additional data from interviews, observation reports, and journals of twelve adult learners allowed the researcher to examine students' perceptions of their interactions with other students and between students and their computers, thus promoting an understanding of the context in which learning to write took place.Findings indicated that adult learners' apprehension scores toward writing and computers decreased by the end of the semester in the computer-based classroom. Qualitative data revealed that the computer-based classroom provided a context that enabled students to form supportive peer groups which helped and impacted their writing, allowing them to develop fluid processes for writing with computers.This study has particular relevance for understanding how adults learn to write in various settings. Adult learners are a special population with unique needs. Apprehension toward writing and computers affects adult learners' attitudes toward writing, many times causing them to drop out of educational programs. This study illuminates the problems and feelings adults face as they learn to write using computers. / Department of Educational Leadership

THESIS ABSTRACT Word final positions are sometimes described as optionally salient, depending on the presence or the absence of bound morphology. In fact, word final positions often incur disruptive phonological processes (such as deletion or assimilation) but these processes are partially blocked in the presence of bound morphology. Some evidence suggests that these effects may also be active in the sublexicon (i.e. with no access to semantics). Investigations of this phenomenon so far focused on monolingual speakers, and little is known about the presence of these effects on speakers with English as their L2. This diploma thesis aims at partially filling this gap by focusing on the perceptual salience of word endings as perceived by second- language learners of English having Czech as their L1. The methodology is based on Cilibrasi (2015). The subjects tested were adult second- language learners of English of different language levels (B1, B2 and C1). In the experimental part, they were asked to listen to pairs of non-words and decide if the non-words are identical or slightly different by pressing one of two keys. There were three conditions: Condition 1 with non-words containing potential morphological information, condition 2 with non-words with no morphological information and condition 3 as a control...

Die Einflüsse von Emotionen auf Informationsverarbeitungsprozesse zählen zu einem der zentralen Aspekte kognitionspsychologischer und neurowissenschaftlicher Forschung. Studien zur Prozessierung affektiver Bilder und emotionaler Gesichtsausdrücke haben gezeigt, daß emotionale Stimuli – vermutlich aufgrund ihrer starken intrinsischen Relevanz für den Organismus – in besonderem Maße Aufmerksamkeit binden und hierdurch einer präferierten und elaborierteren Weiterverarbeitung zugeführt werden. Evidenz zur Aktivierung und Verarbeitung emotionaler Valenz in der visuellen Wortverarbeitung ist hingegen gering und größtenteils inkonsistent. In einer Serie von Experimenten, die in der vorliegenden Arbeit zusammenfassend beschrieben und diskutiert werden, wurde mit Hilfe Ereigniskorrelierter Potentiale (EKPs) versucht, die Effekte emotionaler Valenz von deutschsprachigen Verben innerhalb des Wortverarbeitungsprozesses zu lokalisieren. In den EKPs zeigen sich – hinsichtlich ihrer Latenz und Topographie – dissoziierbare emotionsrelatierte Komponenten, die mit unterschiedlichen Stufen der Verarbeitungsprozesse in Verbindung gebracht werden können. Die Befunde legen nahe, daß die emotionale Valenz von Verben auf einer (post-) lexikalischen Verarbeitungsstufe aktiviert wird. Dieser frühen Registrierung liegen wahrscheinlich domänenunspezifische neuronale Mechanismen zugrunde, die weitestgehend ressourcen- und aufgabenunabhängig wirken. Auf späteren Stufen hingegen scheinen emotions-relatierte Prozesse durch zahlreiche weitere Faktoren beeinflußt zu werden. Die Modulation der Dynamik früher, nicht aber später Emotionsprozessierung durch nicht-valente Kontextinformation sowie in Abhängigkeit der Stimulusdomäne legt einen zeitlich variablen Verarbeitungsprozeß emotionaler Information nahe, der mit streng seriellen Modellen der Informationsverarbeitung nicht vereinbar ist, und möglicherweise der flexiblen Verhaltensanpassung an verschiedene Umweltbedingungen dient. / In recent cognitive and neuroscientific research the influences of emotion on information processing are of special interest. As has been shown in several studies on affective picture as well as facial emotional expression processing, emotional stimuli tend to involuntarily draw attentional resources and preferential and sustained processing, possibly caused by their high intrinsic relevance. However, evidence for emotion effects in visual word processing is scant and heterogeneous. As yet, little is known about at which stage and under what conditions the specific emotional content of a word is activated. A series of experiments which will be summarized and discussed in the following section aimed to localize the effects of emotion in visual word processing by recording event-related potentials (ERPs). Distinct effects of emotional valence on ERPs were found which were distinguishable with regard to their temporal and spatial distribution and might be therefore related to different stages within the processing stream. As a main result, the present findings indicate that the activation of emotional valence of verbs occurs on a (post-) lexical stage. The underlying neural mechanisms of this early registration appear to be domain-unspecific, and further, largely independent of processing resources and task demands. On later stages, emotional processes are modulated by several different factors. Further, the findings of an acceleration of early but not late emotion effects caused by neutral context information as well as by domain-specifity indicate a flexible dynamic of emotional processes which would be hard to account for by strictly serial processing models.

Ce mémoire en recherche création débute par un récit poétique rédigé par fragments et intitulé Ma mère est une porte. Ce texte met en abyme les ruines afin de démontrer leur lien de contiguïté avec l’absence, l’empreinte, la mémoire et la mort. D’ailleurs, leur aspect ruiniforme rappelle le fragment, ce qui permet d’appuyer l’esthétique formelle de l’œuvre. La deuxième partie intitulée Approche génétique : un monument à la mémoire des disparus emportés par le temps de l’écriture, propose une réflexion sur l’imaginaire des ruines en lien avec les archives littéraires et la mémoire. Divisé en trois sections, cet essai pose un regard inquiet sur l’avenir de l’objet d’étude de la critique génétique, soit le manuscrit moderne. Depuis l’avènement de l’informatique et du traitement de texte, que conserverons-nous de la mémoire scripturale et du processus d’écriture de l’écrivain de demain? / This M.A. Thesis combining research and creative writing is divided in two parts: a poetic narrative and an essay. Ma mère est une porte is structured in fragments and contains the mise en abyme of ruins in order to demonstrate that they closely relate to the ideas of absence, genetic footprint, memory and death. Ruins suggest fragments, thus the narrative’s esthetical form. The second part, Approche génétique : un monument à la mémoire des disparus emportés par le temps de l’écriture, is an essay reflecting on the metaphorical link between manuscript, ruins, archives and memory. Divided in three sections, it posits that new technology will cause modern manuscripts to disappear and the methodology behind genesis of text’s to evolve. Moreover, this will change how creative writing’s memory is preserved, hence affecting our cultural heritage.

O objetivo deste estudo foi verificar a elaboração e a recontagem de histórias de crianças com o diagnóstico de depressão maior unipolar (DSM-IV, 1997), bem como a influência da terapia medicamentosa com fluoxetina em um estudo duplo-cego longitudinal controlado com placebo. Fizeram parte do estudo trinta sujeitos com idades entre 10 e 14 anos e diagnosticados com depressão, randomizados para o uso de fluoxetina ou placebo. Ambos os grupos foram avaliados quanto à elaboração livre de textos orais e escritos e à recontagem de textos (fábulas de Êsopo ou La Fontaine) na etapa 0 (sem o uso de medicação) e na etapa 3 (três meses após a introdução de medicação ou placebo). Os textos foram analisados de acordo com o modelo de Kintsch e Van Dijk (1978), baseado no número de macro e microestruturas produzidas e/ou recordadas e nos componentes relativos à superestrutura textual. A este modelo foi acrescida a análise do conteúdo proposicional (positivo, negativo ou neutro), com o intuito de observar o fenômeno da “memória condizente com o humor". Não foram observadas diferenças significativas com relação a esses critérios entre os grupos ou períodos analisados, nem quanto à produção e/ou recontagem de textos orais ou escritos, mesmo com a melhora da sintomatologia clínica observada por meio da escala CDRS (Poznanski & Mokros, 1996). / The aim of this study was to evaluate the textual production and recontagem of children with unipolar major depression (DSM-IV, 1997), and the influence of drug therapy with fluoxetine in a longitudinal, double-blinded, placebo-controlled study. Thirty subjects with depression, aged between 10 and 14 years, were selected and randomized for the use of fluoxetine or placebo. Both groups were analyzed regarding to spontaneous oral and written production and to the recontagem of the texts (Esopo’s or La Fontaine’s fables) in the period zero (without medication) and period 3 (three months after starting placebo or fluoxetine). The texts were analyzed according to Kintsch and Van Dijk’s model (1978), taking in account the number of macro and microstructures elaborated and/or recalled and the textual superstructure. We added to this model the proposition-content analysis (positive, negative or neutral), in order to observe the “mood-congruent memory" phenomenon. Regarding these criteria, no differences were found amongst the groups or periods analyzed, neither amongst the oral and written elaborated or recontados texts, even after the improvement of clinical symptoms evaluated by CDRS scale (Poznanski and Mokros, 1996).
