Perspectives of female leaders on sense of coherence and mental health in an engineering environment
(2013)
Orientation: Positive organisational behaviour impacts strongly on various individual and work-related outcomes. Gender perspectives in this paradigm have not yet been comprehensively researched.
Research purpose: This article explores female perspectives on mental health and sense of coherence. The aim is to promote an understanding of gender-related subjective perceptions on mental health and sense of coherence from an emic perspective.
Motivation for the study: Limited research exists regarding the perceptions of positive leadership behaviour of female leaders within South African who experience unique challenges within the business environment and remain healthy at the same time.
Research design, approach and method: Data from a mixed-method research study are presented, thereby providing insights into quantitative and in-depth qualitative empirical data from 15 female leaders. The study followed a single, embedded case study approach.
Main findings: The main findings show that sense of coherence, mental health and gender awareness are connected. Female leaders with a high sense of coherence refer to gender in a positive or neutral way in a male-dominated work environment. The results emphasise individual and social health-promoting strategies in an organisation and the way personal life orientation contributes to individual (mental) health.
Practical/managerial implications: Organisations need to focus more on promoting mental health in terms of gender and gender-related positive psychology frames.
Contribution/value-add: This study contributes to the literature on gender within the positive organisational behaviour paradigm, presents recommendations for future research and highlights the practical implications for organisations.
Human deep sleep is characterized by reduced sensory activity, responsiveness to stimuli, and conscious awareness. Given its ubiquity and reversible nature, it represents an attractive paradigm to study the neural changes which accompany the loss of consciousness in humans. In particular, the deepest stages of sleep can serve as an empirical test for the predictions of theoretical models relating the phenomenology of consciousness with underlying neural activity. A relatively recent shift of attention from the analysis of evoked responses toward spontaneous (or “resting state”) activity has taken place in the neuroimaging community, together with the development of tools suitable to study distributed functional interactions. In this review we focus on recent functional Magnetic Resonance Imaging (fMRI) studies of spontaneous activity during sleep and their relationship with theoretical models for human consciousness generation, considering the global workspace theory, the information integration theory, and the dynamical core hypothesis. We discuss the venues of research opened by these results, emphasizing the need to extend the analytic methodology in order to obtain a dynamical picture of how functional interactions change over time and how their evolution is modulated during different conscious states. Finally, we discuss the need to experimentally establish absent or reduced conscious content, even when studying the deepest sleep stages.
Seit seinem Erscheinen im Jahr 1919 stand das 'Tagebuch eines halbwüchsigen Mädchens' im Zentrum des öffentlichen Interesses. Die Aufzeichnungen, die von der zunächst anonym bleibenden Herausgeberin, der Wiener Kinder-Analytikerin Hermine Hug-Hellmuth, als "Kulturdenkmal unserer Zeit" präsentiert und von Sigmund Freud als kulturhistorisches Dokument ersten Ranges gewürdigt wurden, erwiesen sich nur wenige Jahre nach ihrer Publikation als Werk der Analytikerin selbst. Dass das Tagebuch als 'authentisches' Zeugnis so erfolgreich war - bereits in den ersten Jahren wurden 10.000 Exemplare verkauft - und sich als Fälschung so wirksam entfalten konnte, hatte mit seinem spezifischen kulturellen und wissenschaftlichen Umfeld zu tun. Denn Hug-Hellmuth war nicht nur fest in die psychoanalytische Bewegung eingebunden, auch hatte sie sich in dem im Entstehen begriffenen kinderpsychoanalytischen Diskurs der 1910er Jahre bereits einen Namen gemacht - und so die für eine Fälschung unabdingbaren Qualifikationen erworben. Vor allem aber lag die Durchschlagskraft des Tagebuchs in seiner wissenschaftsinternen Bedeutung: Versprach es doch, als gleichsam verschriftlichter 'Originalton', Freuds Theorie von der kindlichen und adoleszenten Sexualität sowie deren Bedeutung für die Ätiologie der Neurosen zu belegen und somit eine der wichtigsten Hypothesen der Psychoanalyse auf empirische Grundlagen zu stellen. So sollte das intime Jugendtagebuch, das sich schon qua Genre als 'unverfälschte' und unverstellte Selbstaussage präsentierte, den lang ersehnten Einblick in die Blackbox der adoleszenten Seele ermöglichen, jenen psychischen Raum also, der sich der pädagogischen Kontrolle ebenso wie der auf Erwachsene eingestellten Psychoanalyse entzog.
When reading conflicting science-related texts, readers may attend to cues which allow them to assess plausibility. One such plausibility cue is the use of graphs in the texts, which are regarded as typical of ‘hard science’. The goal of our study was to investigate the effects of the presence of graphs on the perceived plausibility and situation model strength for conflicting science-related texts, while including the influence of readers’ domain knowledge and their knowledge about scientific visualization conventions as potential moderators of these effects. In an experiment mimicking web-based informal learning, 77 university students read texts on controversial scientific issues which were presented with either graphs or tables. Perceived plausibility and situation model strength for each text were assessed immediately after reading; reader variables were assessed several weeks prior to the experiment proper. The results suggest that graphs can indeed serve as plausibility cues and thus boost situation model strength for texts which contain them. This effect was mediated by the perceived plausibility of the information in the texts with graphs. However, whether readers use graphs as plausibility cues in texts with conflicting information seems to depend also on their amount of experience with scientific texts and graphs.
in den letzten 15 Jahren haben Hochschulen neben den traditionellen Lehr- und Lernformen zahlreiche neue Lerndesigns entwickelt und etabliert, die vor allem auf dem Einsatz computer- und netzwerkbasierter Technologien beruhen. Sie führen zu einer Veränderung der Angebotsstrategien in der universitären Lehre, da neue Zielgruppen ansprechbar werden. Neue Lerndesigns sind vor allem dann effektiv, wenn eine strategische didaktische Verzahnung mit klassischen Lerndesigns im Sinne eines Blended Learning stattfindet.
To many psychoanalysts dreams are a central source of knowledge of the unconscious-the specific research object of psychoanalysis. The dialog with the neurosciences, devoted to the testing of hypotheses on human behavior and neurophysiology with objective methods, has added to psychoanalytic conceptualizations on emotion, memory, sleep and dreams, conflict and trauma. To psychoanalysts as well as neuroscientists, the neurological basis of psychic functioning, particularly concerning trauma, is of special interest. In this article, an attempt is made to bridge the gap between psychoanalytic findings and neuroscientific findings on trauma. We then attempt to merge both approaches in one experimental study devoted to the investigation of the neurophysiological changes (fMRI) associated with psychoanalytic treatment in chronically depressed patients. We also report on an attempt to quantify psychoanalysis-induced transformation in the manifest content of dreams. To do so, we used two independent methods. First, dreams reported during the cure of chronic depressed analysands were assessed by the treating psychoanalyst. Second, dreams reported in an experimental context were analyzed by an independent evaluator using a standardized method to quantify changes in dream content (Moser method). Single cases are presented. Preliminary results suggest that psychoanalysis-induced transformation can be assessed in an objective way.
The approximate number system (ANS) is assumingly related to mathematical learning but evidence supporting this assumption is mixed. The inconsistent findings might be attributed to the fact that different measures have been used to assess the ANS and mathematical skills. Moreover, associations between the performance on a measure of the ANS and mathematical skills may be discontinuous, i.e., stronger for children with lower math scores than for children with higher math scores, and may change with age. The aim of the present study was to examine the development of the ANS and arithmetic skills in elementary school children and to investigate how the relationship between the ANS and arithmetic skills develops. Individual markers of children's ANS (internal Weber fractions and mean reaction times in a non-symbolic numerical comparison task) and addition skills were assessed in their first year of school and 1 year later. Children showed improvements in addition performance and in the internal Weber fractions, whereas mean reaction times in the non-symbolic numerical comparison task did not change significantly. While children's addition performance was associated with the internal Weber fractions in the first year, it was associated with mean reaction times in the non-symbolic numerical comparison task in the second year. These associations were not found to be discontinuous and could not be explained by individual differences in reasoning, processing speed, or inhibitory control. The present study extends previous findings by demonstrating that addition performance is associated with different markers of the ANS in the course of development.
Developmental differences in the structure of executive function in middle childhood and adolescence
(2013)
Although it has been argued that the structure of executive function (EF) may change developmentally, there is little empirical research to examine this view in middle childhood and adolescence. The main objective of this study was to examine developmental changes in the component structure of EF in a large sample (N = 457) of 7–15 year olds. Participants completed batteries of tasks that measured three components of EF: updating working memory (UWM), inhibition, and shifting. Confirmatory factor analysis (CFA) was used to test five alternative models in 7–9 year olds, 10–12 year olds, and 13–15 year olds. The results of CFA showed that a single-factor EF model best explained EF performance in 7–9-year-old and 10–12-year-old groups, namely unitary EF, though this single factor explained different amounts of variance at these two ages. In contrast, a three-factor model that included UWM, inhibition, and shifting best accounted for the data from 13–15 year olds, namely diverse EF. In sum, during middle childhood, putative measures of UWM, inhibition, and shifting may rely on similar underlying cognitive processes. Importantly, our findings suggest that developmental dissociations in these three EF components do not emerge until children transition into adolescence. These findings provided empirical evidence for the development of EF structure which progressed from unity to diversity during middle childhood and adolescence.
Different lines of evidence suggest that children's mental representations of numbers are spatially organized in form of a mental number line. It is, however, still unclear whether a spatial organization is specific for the numerical domain or also applies to other ordinal sequences in children. In the present study, children (n = 129) aged 8–9 years were asked to indicate the midpoint of lines flanked by task-irrelevant digits or letters. We found that the localization of the midpoint was systematically biased toward the larger digit. A similar, but less pronounced, effect was detected for letters with spatial biases toward the letter succeeding in the alphabet. Instead of assuming domain-specific forms of spatial representations, we suggest that ordinal information expressing relations between different items of a sequence might be spatially coded in children, whereby numbers seem to convey this kind of information in the most salient way.
