Eye Movements Indicate the Temporal Organisation of Information Processing in Graph Comprehension

Hierarchical graphs (e.g. file system browsers and preference trees) represent objects (e.g. files and folders) as graph nodes and relations between them (e.g. sub‐folder relations) as lines. We investigated the temporal organisation of two processes that are necessary for comprehending such graphs—search for the graph nodes and reasoning about their relation. We tracked eye movements to change graphs while participants interpreted them. In Experiment 1, we masked the graph at a time when search processes had finished but reasoning was hypothetically ongoing. We observed a dramatic deterioration in comprehension compared with unmasked graphs. In Experiment 2, we changed the relation between critical graph nodes after search for them had finished, unbeknownst to participants. Participants mostly based their response on the graph as presented after the change. These results suggest that comprehension processes are organised in a sequential manner, an observation that can potentially be applied to the interactive presentation of graphs.

„Pervasive refusal syndrome“

Pervasive refusal syndrome (PRS), as a new psychiatric disorder among children and adolescents, was first described 1991 by Lask et al. It is characterized by a determined refusal of the child to eat, talk, walk, care for themselves or participate in daily activities. An organic explanation for the symptoms is absent. The observed refusal of functions can be either active or passive. Children also demonstrate a clear resistance to help or treatment. This paper presents a case study that depicts PRS from the therapists’ and the patients’ viewpoint and helpful elements in therapy are evinced from both points of view.     

Eltern und Patienten als Subjekt der Behandlung

Background

There are hardly any alternatives to inpatient treatment for children and adolescents in need of intensive psychiatric treatment. In the randomized study BeZuHG (“behandelt zu Hause gesund werden”, treated at home become healthy), equality of treatments could be shown in the outcome parameters when comparing TAU (inpatient treatment) and the new treatment module BeZuHG (early discharge followed by intensive home treatment enhanced by clinical elements). Patient satisfaction with each treatment module was evaluated at follow-up.

Material and methods

In this study 144 parents and patients of the intervention group (n?=?79) and the control-group (n?=?65) were interviewed after an average of 8 months. Information on expectations, experience with BeZuHG, changes in communication and interaction within the family as well as problem solving strategies (and sustainability of the changes), overall satisfaction and treatment suggestions for modification of the BeZuHG treatment were collected in semistructured telephone interviews.

Results

The following aspects in the BeZuHG treatment were rated as important by parents and patients: support and help with transfer problems, single sessions, a trusting therapeutic relationship as well as treatment setting at home. Enhanced problem solving skills as well as improved family communication were noticed. In the intervention group 70?% would prefer the BeZuHG setting to inpatient care and 46?% in the control group.

Conclusion

The BeZuHG concept is a good and functional alternative to inpatient treatment. Continuity in treatment and therapeutic relationships are essential for successful treatment at home. Positive treatment results within the family as well as the patient remain stable at follow-up after 8 months.     

Psychosomatische Rehabilitation

Besides inpatient and outpatient treatment, rehabilitation represents the third column of the German healthcare system. The goal for the persons concerned is the conservation of activity and participation in the professional and social life. This article shows the importance and development of German psychosomatic rehabilitation in contrast to regular inpatient treatment. It also explains its place in the whole healthcare concept of rehabilitation and the basic principles of sociomedical assessment, followed by practical advice for the indications and the rehabilitation application process. Compared with other countries Germany has a very well-established system of psychosomatic rehabilitation but this resource is often used too late in the course of treatment, mostly not until severe chronification has occurred and in addition there are also problems with points of interaction concerning the subsequent outpatient treatment. The aim of this article is therefore to contribute to an improved cross-linking of the different areas in the healthcare system.     

Useful lies: The twisted rationality of denial

He who increases knowledge increases sorrow.

Ecclesiastes 1:18

The truth will set you free.

John 8:32

Denial, or the habit of treating a real problem as if it were a nonissue, has both rational and irrational features. The interplay between these is best captured by a utilitarian-rationalist framework stretched to its limits. When in denial, people follow what they feel to be in their best interest by minimizing the psychosocial cost of acknowledging their problems. At its core, denial is thus based on a self-interested rationale of pain avoidance and harm minimization. Depending on the characteristics of the issue at hand, some of the effects are deeply ironic. I demonstrate this by starting from the simplest and most beneficial form of denial, before moving on to cases that are more complex and harmful. I also show how people can be liberated from denial when the practice has become counterproductive. Most of the mystery surrounding denial disappears when we accept that it is premised on a twisted kind of rationality.     

Unity in Christ or Pan-Europeanism? Nathan Söderblom and the ecumenical peace movement in the interwar period

In the summer of 2014 the Swedish Church is celebrating the 100th anniversary of the appointment of Nathan Söderblom as archbishop of Uppsala, and thus head of the Swedish church organisation. As a Lutheran with an enormously broad-minded and broad-reaching approach to ecumenical understanding and community-building, Söderblom shot to prominence in the interwar period not only because of his ecumenical engagement, calling for an evangelical catholicity so stand side by side with the Roman catholic and Orthodox catholic traditions, but also because of his comprehensive secular engagement for peace and understanding between peoples. In the latter context he also acquired a solid reputation as a perhaps less prominent but still noteworthy figure in the history of European integration. This article investigates how, why and to what extent Söderblom’s ecumenical and secular engagements were intertwined. The first part discusses how his biographical and academic background led to such staunch ecumenical positions, while the second part focuses on the secular engagement, which was perceived by Söderblom as necessary to make progress on the ecumenical front in the practical political realities of the 1920s. The final part, comparing and contrasting Söderblom’s views with those of Count Richard von Coudenhove-Calergi and the Pan-European Union, demonstrates why Söderblom’s engagement for Europe had to be limited: unity in Christ is by definition global in nature and therefore cannot be continent-specific.     

Egg incubation effects generate positive correlations between size,speed and learning ability in young lizards

Previous studies have suggested that body size and locomotor performance are targets of Darwinian selection in reptiles. However, much of the variation in these traits may derive from phenotypically plastic responses to incubation temperature, rather than from underlying genetic variation. Intriguingly, incubation temperature may also influence cognitive traits such as learning ability. Therefore, we might expect correlations between a reptile’s size, locomotor speed and learning ability either due to selection on all of these traits or due to environmental effects during egg incubation. In the present study, we incubated lizard eggs (Scincidae: Bassiana duperreyi) under ‘hot’ and ‘cold’ thermal regimes and then assessed differences in hatchling body size, running speed and learning ability. We measured learning ability using a Y-maze and a food reward. We found high correlations between size, speed and learning ability, using two different metrics to quantify learning (time to solution, and directness of route), and showed that environmental effects (incubation temperature) cause these correlations. If widespread, such correlations challenge any simple interpretation of fitness advantages due to body size or speed within a population; for example, survivors may be larger and faster than nonsurvivors because of differences in learning ability, not because of their size or speed.
