Lexical Quality and Reading Comprehension in Primary School Children

In a cross-sectional study, we examined the relationship between the quality of lexical representations and text comprehension skill in German primary school children (Grades 1–4). We measured the efficiency and accuracy of orthographical, phonological, and meaning representations by means of computerized tests. Text comprehension skill was assessed with a standardized reading test with questions requiring recognition of text information and inferencing. Both the accuracy of and the efficiency of access to the three types of lexical representations contributed to explaining interindividual variation in text comprehension skill. Results from a path-analytic model suggest a specific causal order of the three components of lexical quality with the quality of meaning representations partly mediating the effects of form representations.

Comprehension of Multiple Documents With Conflicting Information: A Two-Step Model of Validation

In this article, we examine the cognitive processes that are involved when readers comprehend conflicting information in multiple texts. Starting from the notion of routine validation during comprehension, we argue that readers' prior beliefs may lead to a biased processing of conflicting information and a one-sided mental model of controversial issues (text-belief consistency effect). An important distinction is that such biases occur routinely as a by-product of basic comprehension processes. However, readers can actively engage in strategies that work against the biasing effects of prior beliefs when they possess the relevant cognitive resources and are motivated to activate them. A review of published studies that examined belief effects in multiple text comprehension supports the two-step model of validation. We discuss implications of this model for multiple text comprehension and educational practice and delineate directions for future research.     

The developmentalist and the study of biological risk: a view of the past with an eye toward the future

This paper has 2 goals: to review the history of the developmental study of infants and children at biological risk and to appraise the current state of the art. The scope of the review is from 1920 to the present and emphasizes the role of developmentalists. 4 research phases are identified, each reflecting aspects of the social, political, health, and psychological zeitgeist. First, from 1920 to World War II, research was primarily "catalog" and had diverse themes; however, several issues were raised that continue to have relevance. Second, during the postwar years, research often focused on the cognitive and emotional residuals of handicaps, particularly cerebral palsy and poliomyelitis. Third, the 1960s marked the funding of major seminal longitudinal investigations of perinatal risk factors, and studies of very young infants "at risk." And fourth, in the last and current period, technological advances of the 1970s first applied to research with normally developing children were then extended to at-risk groups and revolutionized the methods of studying risk. Finally, we suggest that, although a considerable amount of information has been obtained about developmental phenomena subsequent to biological risk, our research literature is fragmented and difficult to synthesize. We conclude by offering strategies to foster research and the integration of knowledge.     

Stress and Resources in Vocational Problem Solving

By adapting the job demands-resources model of Demerouti et al. Journal of Applied Psychology, 86(3), 499–512, (2001) to vocational problem-solving situations, we aimed to investigate how, and to what extent, problem-solving demands and personal resources affect stress responses and task interest. Therefore, we used a problem-solving task from the business administration domain in a computer-based office simulation. We assigned 58 participants into two groups. The treatment group worked on the problem scenario, whereas the control group was instructed to inspect the computer-based scenario and to check the software’s usability without solving the problem. Problem-solving demands, perceived stress, task interest, cardiovascular parameters, and cortisol concentration were assessed before, during and after the task at several time points. The vocational problem-solving task was associated with perceived time pressure, uncertainty, mental effort, task difficulty, and perceived stress. In addition, we found higher heart rate and cortisol concentration and lower heart rate variability values in the treatment group (compared to the control group) at the end of the task. Furthermore, we found that content knowledge buffers the impact of problem-solving demands on stress responses and it maintains task interest under high mental effort. Overall, we found evidence that vocational problem-solving activities bear stress-evoking potential and personal resources may provide buffering and maintaining functions.     

The effects of developmental delay on sustained attention in young children

The development of developmentally delayed young children is similar to that of normal children in sequence and organization. The hypothesis of this research was that delayed children do differ from the norm when tasks involve discerning nuances, balancing competing stimuli, or acquiring and retaining selected information. Using a videotaped free-play situation, we examined attention deployment behaviors of 3 groups: normally developing (ND), Down syndrome (DS), and developmentally delayed with uncertain etiology (UE). Gesell DQ scores ranged from 50 to 75 in the latter 2 samples. In Study 1, infants had developmental ages of 12-24 months. The UE subjects spent less time engaged with toys than ND or DS subjects, and both delayed groups had less simultaneous appraisal of the environment, more time unoccupied in any way, and more throwing behavior than the ND group. In Study 2, at the 22-30-month developmental age range, DS and UE subjects had patterns of play that included many primitive activities such as banging and mouthing. Taken together, the results show reductions in ongoing acquisition and elaboration of information during play; these in turn may have significant developmental ramifications.     

Exzellenz durch Internationalität

Like excellence, internationality has evolved into a key concept for German universities. This article reconstructs the manifold genesis of internationality as a principle for stratificatory claims on the basis of science policy documents. At the levels of student exchange, researcher mobility, and university cooperation, three changes are elaborated upon: the transition from the medieval universitas of the nationes to the national university, the increasing competitive orientation of a concept of internationality based on cooperation and cultural exchange, and the transformation of internationality under the auspices of excellence. At the same time, it will be shown how international understanding, exchange, and competition as guiding principles of an internationalization discourse are enacted differently in varying historical contexts. It will be demonstrated that internationality as a sign of excellence becomes a strategy for universities to position themselves as superior in their respective fields.

The Use of a Mobile Learning Tool by Medical Students in Undergraduate Anatomy and its Effects on Assessment Outcomes

Hand-held devices have revolutionized communication and education in the last decade. Consequently, mobile learning (m-learning) has become popular among medical students. Nevertheless, there are relatively few studies assessing students' learning outcomes using m-learning devices. This observational study presents an anatomy m-learning tool (eMed-App), an application developed to accompany an anatomy seminar and support medical students' self-directed learning of the skeletal system. Questionnaire data describe where, how frequently, and why students used the app. Multiple choice examination results were analyzed to evaluate whether usage of the app had an effect on test scores. The eMed-App application was used by 77.5% of the students, mainly accessed by Android smartphones, and at students' homes (62.2%) in order to prepare themselves for seminar sessions (60.8%), or to review learning content (67%). Most commonly, students logged on for less than 15 minutes each time (67.8%). Frequent app users showed better test results on items covering eMed-App learning content. In addition, users also achieved better results on items that were not related to the content of the app and, thus, gained better overall test results and lower failure rates. The top quartile of test performers used the eMed-App more frequently compared to students in lower quartiles. This study demonstrated that many students, especially the high-performing ones, made use of the eMed-App. However, the app itself did not result in better outcomes, suggesting that top students might have been more motivated to use the app than students who were generally weak in anatomy.
