    Emotions are an integral part of why and how we use language in everyday life. We communicate our concerns, express our woes, and share our joy through the use of non-verbal and verbal language. Yet there is a limited understanding of when and how emotional language is processed differently to neutral language, or of how emotional information facilitates or inhibits language processing. Indeed, various efforts have been made to bring back emotions into the discipline of psycholinguistics in the last decade. This can be seen in many interdisciplinary models focusing on the role played by emotion in each aspect of linguistic experience. In this thesis, I answer this call and pursue questions that remain unanswered in psycholinguistics regarding its interaction with emotion. The general trend that I am using to bring emotion into psycholinguistic research is straightforward. Where applicable and relevant, I use well-established tasks or paradigms to investigate the effects of emotional content in language processing. Hence, I focused on three main areas of language processing: comprehension, production and prediction. The first experimental chapter includes a series of experiments utilising the Modality Switching Paradigm to investigate whether sentences describing emotional states are processed differently from sentences describing cognitive states. No switching effects were found consistently in my 3 experiments. My results suggest that these distinct classes of interoceptive concepts, such as ‘thinking’ or ‘being happy’, are not processed differently from each other, suggesting that people do not switch attention between different interoceptive systems when comprehending emotional or cognitive sentences. I discuss the implications for grounded cognition theory in the embodiment literature. In my second experimental chapter, I used the Cumulative Semantic Interference Paradigm to investigate these two questions: (1) whether emotion concepts interfere with one another when repeatedly retrieved (emotion label objects), and (2) whether similar interference occurs for concrete objects that share similar valence association (emotion-laden objects). This could indicate that people use information such as valence and arousal to group objects in semantic memory. I found that interference occurs when people retrieve direct emotion labels repeatedly (e.g., “happy” and “sad”) but not when they retrieve the names of concrete objects that have similar emotion connotations (e.g., “puppy” and “rainbow”). I discuss my findings in terms of the different types of information that support representation of abstract vs. concrete concepts. In my final experimental chapter, I used the Visual World Paradigm to investigate whether the emotional state of an agent is used to inform predictions during sentence processing. I found that people do use the description of emotional state of an agent (e.g., “The boy is happy”) to predict the cause of that affective state during sentence processing (e.g., “because he was given an ice-cream”). A key result here is that people were more likely to fixate on the emotionally congruent objects (e.g., ice-cream) compared to incongruent objects (e.g., broccoli). This suggests that people rapidly and automatically inform predictions about upcoming sentence information based on the emotional state of the agent. I discuss our findings as a novel contribution to the Visual World literature. I conducted a diverse set of experiments using a range of established psycholinguistic methods to investigate the roles of emotional information in language processing. I found clear results in the eye-tracking study but inconsistent effects in both switching and interference studies. I interpret these mixed findings in the following way: emotional content does not always have effects in language processing and that effect are most likely in tasks that explicitly require participants to simulate emotion states in some way. Regardless, not only was I successful in finding some novel results by extending previous tasks, but I was also able to show that this is an avenue that can be explored more to advance the affective psycholinguistic field

    Essays on Corporate Disclosure of Value Creation

    Information on a firm’s business model helps investors understand an entity’s resource requirements, priorities for action, and prospects (FASB, 2001, pp. 14-15; IASB, 2010, p. 12). Disclosures of strategy and business model (SBM) are therefore considered a central element of effective annual report commentary (Guillaume, 2018; IIRC, 2011). By applying natural language processing techniques, I explore what SBM disclosures look like when management are pressed to say something, analyse determinants of cross-sectional variation in SBM reporting properties, and assess whether and how managers respond to regulatory interventions seeking to promote SBM annual report commentary. This dissertation contains three main chapters. Chapter 2 presents a systematic review of the academic literature on non-financial reporting and the emerging literature on SBM reporting. Here, I also introduce my institutional setting. Chapter 3 and Chapter 4 form the empirical sections of this thesis. In Chapter 3, I construct the first large sample corpus of SBM annual report commentary and provide the first systematic analysis of the properties of such disclosures. My topic modelling analysis rejects the hypothesis that such disclosure is merely padding; instead finding themes align with popular strategy frameworks and management tailor the mix of SBM topics to reflect their unique approach to value creation. However, SBM commentary is less specific, less precise about time horizon (short- and long-term), and less balanced (more positive) in tone relative to general management commentary. My findings suggest symbolic compliance and legitimisation characterize the typical annual report discussion of SBM. Further analysis identifies proprietary cost considerations and obfuscation incentives as key determinants of symbolic reporting. In Chapter 4, I seek evidence on how managers respond to regulatory mandates by adapting the properties of disclosure and investigate whether the form of the mandate matters. Using a differences-in-differences research design, my results suggest a modest incremental response by treatment firms to the introduction of a comply or explain provision to provide disclosure on strategy and business model. In contrast, I find a substantial response to enacting the same requirements in law. My analysis provides clear and consistent evidence that treatment firms incrementally increase the volume of SBM disclosure, improve coverage across a broad range of topics as well as providing commentary with greater focus on the long term. My results point to substantial changes in SBM reporting properties following regulatory mandates, but the form of the mandate does matter. Overall, this dissertation contributes to the accounting literature by examining how firms discuss a central topic to economic decision making in annual reports and how firms respond to different forms of disclosure mandate. Furthermore, the results of my analysis are likely to be of value for regulators and policymakers currently reviewing or considering mandating disclosure requirements. By examining how companies adapt their reporting to different types of regulations, this study provides an empirical basis for recalibrating SBM disclosure mandates, thereby enhancing the information set of capital market participants and promoting stakeholder engagement in a landscape increasingly shaped by non-financial information

    Mapping the Focal Points of WordPress: A Software and Critical Code Analysis

    Get PDF
    Programming languages or code can be examined through numerous analytical lenses. This project is a critical analysis of WordPress, a prevalent web content management system, applying four modes of inquiry. The project draws on theoretical perspectives and areas of study in media, software, platforms, code, language, and power structures. The applied research is based on Critical Code Studies, an interdisciplinary field of study that holds the potential as a theoretical lens and methodological toolkit to understand computational code beyond its function. The project begins with a critical code analysis of WordPress, examining its origins and source code and mapping selected vulnerabilities. An examination of the influence of digital and computational thinking follows this. The work also explores the intersection of code patching and vulnerability management and how code shapes our sense of control, trust, and empathy, ultimately arguing that a rhetorical-cultural lens can be used to better understand code\u27s controlling influence. Recurring themes throughout these analyses and observations are the connections to power and vulnerability in WordPress\u27 code and how cultural, processual, rhetorical, and ethical implications can be expressed through its code, creating a particular worldview. Code\u27s emergent properties help illustrate how human values and practices (e.g., empathy, aesthetics, language, and trust) become encoded in software design and how people perceive the software through its worldview. These connected analyses reveal cultural, processual, and vulnerability focal points and the influence these entanglements have concerning WordPress as code, software, and platform. WordPress is a complex sociotechnical platform worthy of further study, as is the interdisciplinary merging of theoretical perspectives and disciplines to critically examine code. Ultimately, this project helps further enrich the field by introducing focal points in code, examining sociocultural phenomena within the code, and offering techniques to apply critical code methods

    AktivitÀtstracker im Alltag: Charakteristika von Motivation und User Diversity zur ErklÀrung individueller Nutzungstrajektorien

    Get PDF
    Die fortlaufend stĂ€rkere Durchdringung unseres Alltags mit digitalen Technologien wird besonders deutlich durch tragbare GerĂ€te wie Smartphones, auf die jederzeit zugegriffen werden kann. Noch einen Schritt weiter gehen körpernah getragene, vernetzte Self-Tracking-Systeme wie AktivitĂ€tstracker, welche kontinuierlich Bewegungsdaten und physiologische Parameter erfassen, algorithmisch aufbereiten und an die Nutzer*innen als quantifiziertes Feedback, oft zur Verhaltensmodifikation, zurĂŒckmelden. Diese spezifische Form der Interaktion zwischen Mensch und Technologie – körpernah, kontinuierlich, quantifiziert, vernetzt und persuasiv – ist fĂŒr die Ingenieurpsychologie besonders relevant, da sie eine sehr enge Verbindung von Körper und Technik erfordert und spezifische Herausforderungen fĂŒr die StĂ€rkung der Selbstbestimmung ihrer Nutzer*innen bereithĂ€lt. Einerseits dienen AktivitĂ€tstracker der erleichterten Selbstreflexion durch Sichtbarmachung von ZusammenhĂ€ngen, die zuvor verborgen blieben, wie etwa zwischen sportlicher AktivitĂ€t und Ruheherzfrequenz. Andererseits sollen AktivitĂ€tstracker die Motivation fĂŒr körperliche VerhaltensĂ€nderungen steigern. Die Nutzung von AktivitĂ€tstrackern bewegt sich also potenziell in einem Spannungsfeld zwischen der Steigerung von Selbstbestimmung durch erweitertes Wissen sowie Aufzeigen von Handlungsoptionen und der EinschrĂ€nkung der Selbstbestimmung durch persuasive Strategien zur Motivationssteigerung. Dieses Spannungsfeld bedingt neue AnsĂ€tze zur Beziehungsgestaltung zwischen Mensch und Trackingsystem. In der empirischen Forschung zur Nutzung von AktivitĂ€tstrackern wird hĂ€ufig darauf hingewiesen, dass ein Großteil der Nutzenden nach wenigen Wochen oder Monaten den kontinuierlichen Gebrauch beendet. Dieser Befund deutet daraufhin, dass Barrieren existieren, die die Langzeitnutzung unwahrscheinlicher machen. Des Weiteren wird immer wieder ĂŒber negative Effekte der Trackernutzung berichtet, beispielsweise Stress. Allerdings ist auch bekannt, dass zahlreiche andere Personen ihr Trackingsystem ĂŒber Jahre hinweg intensiv und erfolgreich gebrauchen. Es lĂ€sst sich also in Bezug auf die Nutzungstrajektorien eine bedeutsame Varianz feststellen, die es zu erklĂ€ren gilt, um Self-Tracking-Anwendungen fĂŒr diverse Nutzende gewinnbringend zu gestalten. Um diesem Vorhaben gerecht zu werden, ist es unabdingbar zu verstehen, welche individuellen Differenzen in der Gruppe der Nutzer*innen die Interaktion mit dem AktivitĂ€tstracker, insbesondere in Bezug auf motivationale Aspekte, prĂ€gen. Dieser Herausforderung stellt sich die vorliegende Dissertation und greift dazu auf etablierte Theorien und Konzepte der Persönlichkeits- und Sozialpsychologie zurĂŒck. Da der theoriegeleitete Einbezug von Personenmerkmalen in die ingenieurpsychologische Forschung noch wenig vorangetrieben war, bestand zu Beginn des Promotionsvorhabens die Notwendigkeit, ein Konstrukt zu konzeptualisieren, welches zum einen auf einem stabilen psychologischen Theoriefundament steht und zum anderen spezifisch auf den Kontext der Mensch-Technik-Interaktion zugeschnitten ist. Im Rahmen der vorliegenden Dissertation wurde aus diesem Grund an der Herleitung der interaktionsbezogenen TechnikaffinitĂ€t (ATI) als kontextspezifische Variante der Denkfreude und ihrer Messbarmachung gearbei-tet. Insgesamt umfassten die Datenerhebungen zur Bestimmung der GĂŒtekriterien der ATI-Skala fĂŒnf DatensĂ€tze mit ĂŒber 1500 Teilnehmenden. Das Resultat der Skalenentwicklung ist ein unidimensionales, ökonomisches, reliables und valides Erhebungsinstrument der interaktionsbezogenen TechnikaffinitĂ€t (Artikel 1). Als relativ stabiles Persönlichkeitsmerkmal, das die Motivation zur Auseinandersetzung mit Technik grundlegend beeinflusst, wurde ATI in die folgenden Studien zur Interaktion zwischen Mensch und AktivitĂ€tstracker miteinbezogen. Um die alltĂ€gliche, individuelle Mensch-Tracker-Interaktion umfassend zu verstehen und erklĂ€ren zu können, wie es zu den unterschiedlichen NutzungsverlĂ€ufen kommt, mĂŒssen verschiedene Phasen der Nutzung untersucht werden. ZunĂ€chst ist zu klĂ€ren, welche Motivatoren Menschen eigentlich dazu veranlassen, mit der Trackernutzung zu beginnen. Weiterhin ist die Nutzungsphase selbst zu beleuchten, um zu beschreiben, wie sich die oben beschriebene, spezifische Form der Trackerinteraktion auf die Nutzungserfahrung und anhaltende Motivation auswirkt und wie sich negative Nutzungskonsequenzen bemerkbar machen. Schließlich sind zum VerstĂ€ndnis der Nutzungstrajektorien die GrĂŒnde fĂŒr den Abbruch zu berĂŒcksichtigen, sodass auch die Phase nach der Nutzung relevant ist. Da sich diese Dissertation dezidiert damit beschĂ€ftigt, wie sich die Interaktion mit AktivitĂ€tstrackern im Alltag gestaltet, ist die Untersuchung der Nutzung in Stichproben von tatsĂ€chlichen bzw. ehemaligen AktivitĂ€tstracker-Nutzer*innen angezeigt. Aus diesem Grund wurden zwei Online-Erhebungen durchgefĂŒhrt, um ebendiese Stichproben zu erreichen. Das Ziel der ersten Studie (N = 210) war die quantitative Analyse von Nutzungsmotivationen sowie unintendierten, negativen Effekten der Trackernutzung im Alltagsgebrauch. Es zeigte sich, dass das Tracken sowohl zum Selbstzweck (intrinsische Motivation) als auch zur Erreichung eines externen Ziels (extrinsische Motivation) durchgefĂŒhrt wird und diese Motivationstypen oft gleichzeitig auftreten. DarĂŒber hinaus konnte gezeigt werden, dass negative Effekte in Form von Motivationsverlusten in Bezug auf die Trackernutzung und die körperliche AktivitĂ€t eine Rolle im Alltag vieler Nutzer*innen spielen. Die Wahrscheinlichkeit des Auftretens dieser Effekte wird teilweise von Personenmerkmalen wie ATI und der Nutzungsmotivation bestimmt (Artikel 2). Die zweite Studie nahm ehemalige Nutzer*innen (N = 159) in den Blick und fokussierte auf die Erfassung der GrĂŒnde fĂŒr den Nutzungsabbruch sowie die StabilitĂ€t der Abbruchentscheidung. Die Ergebnisse machten deutlich, dass zahlreiche Nutzungsbarrieren fĂŒr die Entscheidung, den Tracker abzulegen, ausschlaggebend sind. Außerdem sind die Abbruchentscheidungen oft nicht permanent, was auf eine episodische Trackernutzung hindeutet (Artikel 3). Schließlich wurden wiederum Personenmerkmale und außerdem Interaktionscharakteristika in Betracht gezogen, um die große Varianz hinsichtlich AbbruchgrĂŒnden und -permanenz zu erklĂ€ren. Die Analysen offenbarten unter anderem, dass eine episodische Nutzung (d. h. nicht endgĂŒltige Beendigung) wahrscheinlicher ist, wenn sich die Nutzungsmotivation durch einen hohen Grad an Selbstbestimmung auszeichnet (Artikel 4). Abschließend betonen die Befunde der Dissertation die zentrale Rolle der wahrgenommenen Selbstbestimmung im Kontext der Mensch-Tracker-Interaktion und geben Anlass fĂŒr Designrichtlinien, die die Beziehung zwischen Trackingsystem und Nutzer*in mit all ihren gegenseitigen AbhĂ€ngigkeiten und individuellen Merkmalen berĂŒcksichtigen, um so die Selbstbestimmung zu erhalten oder sogar durch vertieftes Selbstwissen zu stĂ€rken.The ongoing permeation of our daily life with digital technologies is particularly evident in wearable devices such as smartphones, which can be accessed at any time. Wearable, connected self-tracking systems such as activity trackers go even a step further. They continuously record movement data and physiological parameters, process them algorithmically and provide quantified feedback to the user, often for behavioral modification. This specific form of interaction between humans and technology – close to the body, continuous, quantified, connected, and persuasive – is particularly relevant for engineering psychology, as it requires a very close connection between body and technology and poses specific challenges for strengthening the self-determination of its users. That is, on the one hand, activity trackers serve to facilitate self-reflection by revealing relationships which were previously hidden, such as the relationship between physical activity and resting heart rate. On the other hand, activity trackers are intended to enhance motivation for physical behavioral changes. The use of activity trackers thus potentially moves in a field of tension between the increase of self-determination through expanded knowledge as well as the identification of behavioral options and the restriction of self-determination through persuasive strategies to increase motivation. This tension requires new approaches to the design of relationships between people and tracking systems. Empirical research on activity tracker usage often highlights that a large proportion of users stop continuous use after a few weeks or months. This finding suggests the existence of barriers that make long-term use less likely. Furthermore, negative effects of tracker use, such as stress, are repeatedly reported. However, it is also known that many other users have enjoyed intensive and successful use of their tracking system for many years. Thus, a significant variance in usage trajectories can be observed, which needs to be explained in order to make self-tracking applications beneficial for diverse users. To meet this goal, it is essential to understand which individual differences in the group of users shape the interaction with their activity tracker, especially with respect to motivational aspects. This dissertation addresses this challenge by drawing on established theories and concepts of personality and social psychology. At the beginning of the dissertation project, the theory-based inclusion of personal characteristics in engineering psychology had not yet been sufficiently advanced. Thus, there was a need to conceptualize a construct which, on the one hand, stands on a stable psychological theoretical foundation and, on the other hand, is specifically tailored to the context of human-technology interaction. For this reason, the conceptualization of affinity for technology interaction (ATI) as a context-specific variant of need for cognition and its measurability took place within the context of the dissertation. In total, the data collection to determine the quality criteria of the ATI scale comprised five data sets with over 1500 participants. The result of the scale development is a unidimensional, economical, reliable, and valid survey instrument of ATI (Article 1). As a relatively stable personality trait that fundamentally influences motivation to engage with technology, ATI was included in subsequent studies of human-activity tracker interaction. In order to comprehensively understand the everyday, individual human-tracker interaction and to be able to explain how the various usage patterns occur, different phases of usage must be examined. First, it must be clarified which motivators actually cause a person to start using a tracker. Furthermore, the usage phase itself must be examined to describe how the specific form of tracker interaction described above affects the usage experience and ongoing motivation, and how negative usage consequences become apparent. Finally, to understand usage trajectories, the reasons for discontinuation need to be considered, hence the post-usage phase is also relevant. Since this dissertation decidedly focuses on the interaction with activity trackers in everyday life, the investigation of actual or former activity tracker users is indicated. For this reason, two online surveys were conducted to assess these actual (former) users. The aim of the first study (N = 210) was to quantitatively analyze motivations for usage as well as unintended, negative effects of tracker usage in daily use. It was shown that tracking is performed both for an end in itself (intrinsic motivation) and to achieve an external goal (extrinsic motivation), and that these motivation types often occur simultaneously. Furthermore, it was shown that negative effects in terms of motivation losses with respect to tracker use as well as physical activity play a role in many users' daily lives. The likelihood of these effects occurring is partly determined by personal characteristics such as ATI and motivation for usage (Article 2). The second study examined former users (N = 159) and focused on the reasons for discontinuing use and the stability of abandonment. The results indicated that numerous barriers to use are decisive for the decision to discontinue tracking. In addition, abandonment decisions are often not permanent, suggesting episodic tracker use (Article 3). Finally, person and interaction characteristics were considered to explain the large variance in abandonment reasons and permanence. The analyses revealed, among other things, that episodic use (i.e., not definitive termination) is more likely when the motivation for usage is characterized by a high degree of self-determination (Article 4). In conclusion, the findings of the dissertation emphasize the central role of perceived self-determination in the context of human-tracker interaction and give rise to design guidelines that take into account the relationship between the tracking system and the user with all its interdependencies and individual characteristics in order to preserve or even strengthen self-determination through deeper self-knowledge

    Understanding Agreement and Disagreement in Listeners’ Perceived Emotion in Live Music Performance

    Emotion perception of music is subjective and time dependent. Most computational music emotion recognition (MER) systems overlook time- and listener-dependent factors by averaging emotion judgments across listeners. In this work, we investigate the influence of music, setting (live vs lab vs online), and individual factors on music emotion perception over time. In an initial study, we explore changes in perceived music emotions among audience members during live classical music performances. Fifteen audience members used a mobile application to annotate time-varying emotion judgments based on the valence-arousal model. Inter-rater reliability analyses indicate that consistency in emotion judgments varies significantly across rehearsal segments, with systematic disagreements in certain segments. In a follow-up study, we examine listeners' reasons for their ratings in segments with high and low agreement. We relate these reasons to acoustic features and individual differences. Twenty-one listeners annotated perceived emotions while watching a recorded video of the live performance. They then reflected on their judgments and provided explanations retrospectively. Disagreements were attributed to listeners attending to different musical features or being uncertain about the expressed emotions. Emotion judgments were significantly associated with personality traits, gender, cultural background, and music preference. Thematic analysis of explanations revealed cognitive processes underlying music emotion perception, highlighting attributes less frequently discussed in MER studies, such as instrumentation, arrangement, musical structure, and multimodal factors related to performer expression. Exploratory models incorporating these semantic features and individual factors were developed to predict perceived music emotion over time. Regression analyses confirmed the significance of listener-informed semantic features as independent variables, with individual factors acting as moderators between loudness, pitch range, and arousal. In our final study, we analyzed the effects of individual differences on music emotion perception among 128 participants with diverse backgrounds. Participants annotated perceived emotions for 51 piano performances of different compositions from the Western canon, spanning various era. Linear mixed effects models revealed significant variations in valence and arousal ratings, as well as the frequency of emotion ratings, with regard to several individual factors: music sophistication, music preferences, personality traits, and mood states. Additionally, participants' ratings of arousal, valence, and emotional agreement were significantly associated to the historical time periods of the examined clips. This research highlights the complexity of music emotion perception, revealing it to be a dynamic, individual and context-dependent process. It paves the way for the development of more individually nuanced, time-based models in music psychology, opening up new avenues for personalised music emotion recognition and recommendation, music emotion-driven generation and therapeutic applications
