For the last four decades, psycholinguistic research has dealt with the question to what extent elements of simple sentences like “The monk read the book” are planned ahead both on the abstract-lexical and phonological processing level. While a number of studies have shown that all up to the final element can be activated on these two levels, empirical evidence on the flexibility of the respective planning scopes is inconsistent, and a systematic delineation of the influence of different forms of cognitive load has not yet been provided. This thesis presents a series of 9 picture-word interference experiments in which participants produced subject-verb-object sentences while ignoring auditory distractor words. Advance planning was assessed at an abstract-lexical (lemma) level and at a phonological (word form) level under varying working memory load conditions (no load, or visuospatial load, or verbal load). In the absence of a concurrent working memory load and with a concurrent visuospatial working memory load, subject and object nouns were found to be activated at the abstract-lexical and the phonological level prior to speech onset. By contrast, with a concurrent verbal working load, the scope of advance planning at the phonological level was reduced, while the scope of advance planning at the abstract-lexical level remained unaffected. Moreover, sentence planning had a more disruptive effect on verbal working memory performance than on visuospatial working memory performance. Overall, these results suggest that advance planning at the phonological level is more adaptive to external factors than advance planning at the abstract-lexical level. Also, they indicate an overlap of resources allocated to phonological processing in speech production and verbal working memory.

Diese Dissertation enthält eine theoretische und empirische Untersuchung der Gestaltung interaktiver Lernmedien. Interaktivität wird hierbei breit definiert und umfasst sowohl minimal interaktive Benutzersteuerungen, die Lernenden eine Änderung der Darstellung von Lerninhalten erlauben, bis hin zu voll immersiven Umgebungen in der virtuellen Realität. Theoretisch ist die Dissertation auf den Modellen der Cognitive Load Theory und dem Ansatz der Embodied Cognition verankert. Der Ansatz der Cognitive Load Theory rät zu einem Instruktionsdesign bei dem die kognitive Belastung innerhalb einer Lernaufgabe begrenzt wird, jedoch stellt Forschung im Paradigma der Embodied Cognition zumeist die Vorteile von Aktivität für kognitive Prozesse heraus. Die Kapitel dieser Dissertation zielen darauf ab, diese zwei scheinbar widersprüchlichen Ansätze miteinander zu versöhnen. Kapitel 1 bietet einen Überblick über die Inhalte dieser Dissertation und beschreibt die Implikationen der Resultate. In Kapitel 2 wird ein weitreichender Überblick über Forschung zu Embodied Cognition im Bereich des Lernens (auch bekannt als Embodied Learning) präsentiert und eine Taxonomie des Embodied Learning wird beschrieben. Ein wichtiger Beitrag von Kapitel 2 ist die Betrachtung, dass eine Gestaltung von interaktiven Lernumgebungen, die nicht gegen die Grundsätze der Cognitive Load Theory verstoßen, möglich ist. Kapitel 3 leistet eine Reflexion über Detailfragen zur Messung der kognitiven Belastung bei Aufgaben, in denen körperliche Faktoren oder Interaktivität eine Rolle spielen. Eine wichtige Behauptung aus Kapitel 3 besteht darin, dass es Unterschiede hinsichtlich der Passung verschiedener Messinstrumente der kognitiven Belastung für Aufgaben mit einem unterschiedlichen Lehransatz geben könnte. Die Passung verschiedener Fragebogeninstrumente zur Erfassung der (extrinsischen) kognitiven Belastung wird in Kapitel 4 empirisch evaluiert. In zwei Experimenten wurde die extrinsische Belastung (d.h. jene kognitive Belastung, die aus der Umsetzung einer Lernaufgabe herrührt) mit zwei verschiedenen Fragebogeninstrumenten gemessen. Die Versuchspersonen nutzten dabei entweder eine nicht-interaktive oder eine interaktive Implementation von Lernaufgaben zur Anatomie. Bei einem der Experimente stellte sich heraus, dass der gemessene Unterschied in der extrinsischen Belastung zwischen den beiden Versionen bei einem der Fragebögen hoch und bei dem anderen gering ausfiel. Basierend auf diesem Ergebnis wird in dem Kapitel empfohlen, die extrinsische Belastung nicht als einen einheitlichen Begriff, sondern als eine Ansammlung unterschiedlicher Belastungsarten zu betrachten. Darüber hinaus werden in den drei Experimenten in Kapitel 4 Hypothesen hinsichtlich der Gestaltung von Lerntests für Medien aufgestellt, die interaktive Komponenten verwenden. Zum Abschluss zielt Kapitel 5 darauf ab, allgemeine Empfehlungen zur Verbesserung von Forschung im Paradigma der Embodied Cognition zu formulieren und greift dabei auf die Taxonomie aus Kapitel 2 zurück. Insgesamt betrachtet verwendet diese Dissertation die Ansätze der Embodied Cognition und der Cognitive Load Theory um die Theorien gegenseitig anzuregen und um Ansätze zur Überarbeitung beider Theorien zu bieten. / This dissertation presents a theoretical and empirical investigation of the design of interactive learning media. Interactivity is understood in a broad sense, ranging from minimally interactive user controls allowing learners to change the display of learning contents up to fully immersive virtual reality environments. Theoretically, this dissertation is grounded in the models of cognitive load theory and embodied cognition. Cognitive load theory advises instructional designers to limit the cognitive load involved in a learning task, but embodied cognition research usually focuses on the benefits of activity for cognitive processes. The chapters in this dissertation aim to bridge the gap between these two seemingly contradicting approaches. Chapter 1 offers an overview of the contents of this dissertation and describes the implications of the results. In Chapter 2, an extended overview of embodiment research in the field of learning (also referred to as embodied learning) is presented and a taxonomy of embodied learning is outlined. Chapter 2 highlights that there may be ways of designing interactive learning settings while not infringing upon the principles of cognitive load theory. Chapter 3 affords a reflection on the intricacies of measuring cognitive load in tasks that involve embodiment or interactivity. An important assertion of Chapter 3 is that there may be differences in the suitability of different cognitive load measurement instruments for tasks differing in their instructional approach. The suitability of different cognitive load survey instruments for measuring (extraneous) cognitive load is empirically evaluated in Chapter 4. In two experiments, extraneous load (i.e., cognitive load brought about by the implementation of a learning task) was measured using two different cognitive load surveys. Participants either used a noninteractive or an interactive implementation of anatomy learning tasks. In one experiment, the difference in extraneous load between the two versions was high for one survey and low for another survey. Based on this result, the chapter recommends to view extraneous load not as a uniform concept, but rather as a collection of different load types. Moreover, the three studies in Chapter 4 test hypotheses concerning the design of tests for media using interactive learning components. Finally, Chapter 5 intends to formulate general recommendations for advancing embodied cognition research, thereby drawing on the taxonomy of Chapter 2. In sum, this dissertation uses embodied cognition and cognitive load theory to inform each other and to provide a starting point for upgrades for both theories.

Research on learning and education is increasingly influenced by theories of embodied cognition. Several embodiment-based interventions have been empirically investigated, including gesturing, interactive digital media, and bodily activity in general. This review aims to present the most important theoretical foundations of embodied cognition and their application to educational research. Furthermore, we critically review recent research concerning the effectiveness of embodiment interventions and develop a taxonomy to more properly characterize research on embodied cognition. The main dimensions of this taxonomy are bodily engagement (i.e. how much bodily activity is involved) and task integration (i.e. whether bodily activities are related to a learning task in a meaningful way or not). By locating studies on the 2 × 2 grid resulting from this taxonomy and assessing the corresponding learning outcomes, we identify opportunities, problems, and challenges of research on embodied learning.

PowerPoint is a popular presentation software that is often used in educational settings, however, there is a need for further instruction on how to use the software effectively to facilitate learning. Prior research on the use of PowerPoint in education has been inconclusive as it has been focused on the presence or lack of presence in the classroom, rather than its practical implementation. The current study aims to investigate teachers’ beliefs of using PowerPoint in the classroom, for what purpose they use colors, and image in text in PowerPoint, and to what extent their reported design choices are in line with learning theories related to color, and image and text. To do this, we have interviewed four Swedish ESL teachers and conducted a complimentary survey with 47 ESL teachers. The results show that both survey participants and interviewees considered PowerPoint to be a useful digital tool in the classroom. The survey participants used PowerPoint for language instruction while the interviewees used it for content knowledge. Even if both the survey and interview participants reported practices partially corresponded with current research, it seemed like their design choices were based on instinctive or implicit understanding. With an explicit knowledge of how to design PowerPoint to facilitate learning, teachers could use PowerPoint as a pedagogical tool.

Introduction: Controversy exists in the simulation community as to the emotional and educational ramifications of mannequin death due to learner action or inaction. No theoretical framework to guide future investigations of learner actions currently exists. The purpose of our study was to generate a model of the learner experience of mannequin death using a mixed methods approach. Methods: The study consisted of an initial focus group phase composed of 11 learners who had previously experienced mannequin death due to action or inaction on the part of learners as defined by Leighton (Clin Simul Nurs. 2009;5(2):e59-e62). Transcripts were analyzed using grounded theory to generate a list of relevant themes that were further organized into a theoretical framework. With the use of this framework, a survey was generated and distributed to additional learners who had experienced mannequin death due to action or inaction. Results: were analyzed using a mixed methods approach. Results: Forty-one clinicians completed the survey. A correlation was found between the emotional experience of mannequin death and degree of presession anxiety (P < 0.001). Debriefing was found to significantly reduce negative emotion and enhance satisfaction. Sixty-nine percent of respondents indicated that mannequin death enhanced learning. These results were used to modify our framework. Conclusions: Using the previous approach, we created a model of the effect of mannequin death on the educational and psychological state of learners. We offer the final model as a guide to future research regarding the learner experience of mannequin death.

While the body of evidence supporting the use of simulation-based learning in the education of health professionals is growing, howor why simulation-based learning works is not yet understood. There is a clear need for evidence, grounded in contemporary educational theory, to clarify the features of simulation instructional design that optimize learning outcomes and efficiency in health care professional students. Cognitive Load Theory (CLT) is a theoretical framework focused on a learner’s working memory capacity. One principle of CLT is example based learning. While this principle has been applied in both traditional classroom and laboratory settings, and has shown positive performance and learning outcomes, example based learning has not yet been applied to the simulation setting. This study had two main objectives: to explore if the example-based learning principle could successfully be applied to the simulation learning environment, and to establish response process validation evidence for a tool designed to measure types of cognitive load. Fifty-eight novice students from nursing, podiatric medicine, physician assistant, physical and occupational therapy programs participated in a blinded randomized control study. The dependent variable was the simulation brief. Participants were randomly assigned to either a traditional brief or a facilitated tutored problem brief. Performance outcomes were measured with verbal communications skill presented in the Introduction, Situation, Background, Assessment, Recommendation (I-SBAR) format. Response process evidence was collected from cognitive interviews of 11 students. Results indicate participation in a tutored problem brief led to statistically significant differences at t(52)=-3.259, p=.002 in verbal communication performance compared to students who participated in a traditional brief. Effect size for this comparison was d=(6.06-4.61)/1.63 = .89 (95% CI 0.32-1.44). Response process evidence demonstrated that additional factors unique to the simulationlearning environment should be accounted for when measuring cognitive load in simulation based learning (SBL). This study suggests that example based learning principles can be successfully applied to SBL and result in positive performance outcomes for health professions students. Additionally, measures of cognitive load do not appear to capture all contribution toload imposed by the simulation environment.

These days, everything revolves around technology, and we have instantaneous access to all information. To stay up to date on current events, we get notifications on our smart devices when relevant articles or messages become available. Displays and other forms of technology are ubiquitous in today's car interiors to both enhance the driving experience and keep the driver in touch with the information they provide. However, depending on the situation and task at hand, these notifications can elicit a variety of reactions from us when they appear at an inconvenient time. The problem statement of this research was that there was very little amount of research done on the connection between drivers with different personality traits and how the incoming in-vehicle notifications affect them in various cognitive load scenarios. This study put participants in a practical research where they have been doing a primary task while interacting with notifications as a side task. The tasks at hand have been divided based on the user's cognitive load, or the amount of focus required for that activity, like different driving scenarios in real life. We have collected sufficient data through practical research in which participants have been placed in a scenario of performing a primary task while interacting with incoming notifications. Prior to that, the personality traits of the participants have been determined using a survey, which assisted us in connecting the similarities and differences among the various personality trait groups. In the practical part of the study, a screen was used on which the participant performed a primary task in the form of a video game, as well as a screen beside him, mimicking an infotainment screen, with incoming notifications with which he had to interact. This provided us with accurate data based on its similarity to an actual everyday scenario, such as while driving a car. The findings aided in establishing a clear link between personality traits, levels of cognitive load, and notifications in general, and how they are interlinked.

The state of the art of autonomous vehicles requires operators to remain vigilant while performing secondary tasks. The goal of this research was to investigate how dynamically allocated secondary tasks affected driving performance, cognitive load, and situation awareness. Secondary tasks were presented at rates based on the autonomy level present and whether the autonomous system was engaged. A rapid secondary task rate was also presented for two short periods regardless of whether autonomy was engaged. There was a three-minute familiarization phase followed by a data collection phase where participants responded to secondary tasks while preventing the vehicle from colliding into random obstacles. After data collection, there was a brief survey to gather data on cognitive load, situation awareness, and relevant demographics. The data was compared to data gathered in a similar study by Cossitt [10] where secondary tasks were presented at a controlled frequency and a gradually increasing frequency.

homework problems in an introductory mechanics course at a university. A quasi-experimental field study with two cohorts design was performed to measure the impact of such exercises on motivation, interest and conceptual understanding. The empirical results on learning achievement show a significant positive influence of the smartphone-based experimental exercise for the dynamics of rigid bodies topic with a medium effect size of d =0.42. For the analysis of rotational motion topic, a positive learning achievement for both groups was evidenced, but the effect size of the smartphone-based exercise was rather small at d =0.20 . The intrinsic and germane cognitive loads turned out to be similar at an intermediate level for both groups. However, the extrinsic cognitive load for the intervention group decreased significantly, which might be the reason why more complex experimental exercises foster conceptual understanding.
