Angststörungen bei Patienten mit implantiertem Kardioverter-Defibrillator (ICD)

Patients with an implantable cardioverter defibrillator (ICD) often show anxiety disorders as comorbid psychologycal disturbances. In a short review we discuss psychosocial aspects of the ICD-implantation. A case study of a 38 year old patient in inpatient treatment is presented for illustration of a cognitive-behavioral treatment method. The psychotherapeutic treatment was carried out in close cooperation with the clinic for cardiology.     

Interrogative Belief Revision in Modal Logic

The well known AGM framework for belief revision has recently been extended to include a model of the research agenda of the agent, i.e. a set of questions to which the agent wishes to find answers (Olsson & Westlund in Erkenntnis, 65, 165–183, 2006). The resulting model has later come to be called interrogative belief revision. While belief revision has been studied extensively from the point of view of modal logic, so far interrogative belief revision has only been dealt with in the metalanguage approach in which AGM was originally presented. In this paper, I show how to model interrogative belief revision in a modal object language using a class of operators for questions. In particular, the solution I propose will be shown to capture the notion of K-truncation, a method for agenda update in the case of expansion constructed by Olsson & Westlund. Two case studies are conducted: first, an interrogative extension of Krister Segerberg’s system DDL, and then a similar extension of Giacomo Bonanno’s modal logic for belief revision. Sound and complete axioms will be provided for both of the resulting logics.     

The multinomial model of prospective memory: validity of ongoing-task parameters

The objective of this research was to provide additional experimental validation of the multinomial processing tree (MPT) model of event-based prospective memory (Smith & Bayen, 2004). In particular, the parameters that measure trial-type detection in the ongoing task were examined. In three experiments with different response instructions, event-based prospective memory tasks were embedded in ongoing color-matching tasks. The results support the validity of the MPT model, that is, manipulations of ongoing-task difficulty affected the ongoing-task parameters of the MPT model, while leaving the estimates for the prospective and the retrospective components of prospective memory unaffected.     

On the molecular genetics of flexibility: The case of task-switching,inhibitory control and genetic variants

The adjustment of behavior to changing goals and environmental constraints requires the flexible switching between different task sets. Cognitive flexibility is an endophenotype of executive functioning and is highly heritable, as indicated by twin studies. Individual differences in global flexibility as assessed by reaction-time measurement in a task-switching paradigm were recently related to a single nucleotide polymorphism in the vicinity of the dopamine d2 receptor gene DRD2. In the present study, we assessed whether the DRD2 gene is related to backward inhibition, a control mechanism that contributes to cognitive flexibility by reducing proactive interference by no longer relevant task sets. We found that carriers of the DRD2 A1+ variant who have a lower striatal dopamine d2 receptor density than A1– carriers show a larger backward inhibition effect. This is in line with previous results demonstrating increased behavioral flexibility in carriers of this genetic variant. The discussion relates the present finding to those of previous studies assessing the neurogenetic foundations of inhibitory control.     

Some thoughts on empathy and countertransference

Two aspects of countertransference-namely, the countertransference reaction and empathic understanding-must be distinguished. The term countertransference should be reserved exclusively for the conscious reactions of the analyst emerging from the preconscious by virtue of the patient's current transferences; the term empathy should be used to denote a perspective whereby the analyst employs current countertransference reactions for an understanding of the patient's inner life.     

From Kant to Post-Kantian Idealism: German Idealism: Sebastian Gardner

German idealism has been pictured as an unwarranted deviation from the central epistemological orientation of modern philosophy, and its close historical association with German romanticism is adduced in support of this verdict. This paper proposes an interpretation of German idealism which seeks to grant key importance to its connection with romanticism without thereby undermining its philosophical rationality. I suggest that the fundamental motivation of German idealism is axiological, and that its augmentation of Kant's idealism is intelligible in terms of its combined aim of consolidating the transcendental turn and legitimating the kind of (objectual) relation to value articulated in German romanticism.     

Auditory space perception in left- and right-handers

Several studies have shown that handedness has an impact on visual spatial abilities. Here we investigated the effect of laterality on auditory space perception. Participants (33 right-handers, 20 left-handers) completed two tasks of sound localization. In a dark, anechoic, and sound-proof room, sound stimuli (broadband noise) were presented via 21 loudspeakers mounted horizontally (from 80° on the left to 80° on the right). Participants had to localize the target either by using a swivel hand-pointer or by head-pointing. Individual lateral preferences of eye, ear, hand, and foot were obtained using a questionnaire. With both pointing methods, participants showed a bias in sound localization that was to the side contralateral to the preferred hand, an effect that was unrelated to their overall precision. This partially parallels findings in the visual modality as left-handers typically have a more rightward bias in visual line bisection compared with right-handers. Despite the differences in neural processing of auditory and visual spatial information these findings show similar effects of lateral preference on auditory and visual spatial perception. This suggests that supramodal neural processes are involved in the mechanisms generating laterality in space perception.     

Contraction in Interrogative Belief Revision

In the paper “On the role of the research agenda in epistemic change”, Olsson and Westlund have suggested that the notion of epistemic state employed in the standard framework of belief revision (Alchourrón et al. 1985; G?rdenfors 1988) should be extended to include a representation of the agent’s research agenda (Olsson and Westlund 2006). The resulting framework will here be referred to as interrogative belief revision. In this paper, I attempt to deal with the problem of how research agendas should change in contraction, a problem largely left open by Olsson and Westlund. Two desiderata of an appropriate solution are suggested: one is a principle of continuity, stating that changes in the research agenda should somehow reflect that certain long term research interests are kept fixed. The other desideratum, which is based on part of Olsson and Westlund’s motivation for adding research agendas to the epistemic states, is that we should be able to account for how contraction may serve to open up new, fruitful hypotheses for investigation. In order to achieve these desiderata, I base my solution on a revised version of Olsson and Westlund’s notion of epistemic state.     

Precariousness and Quality of Life—a Qualitative Perspective on Quality of Life of Households in Precarious Prosperity in Switzerland and Spain

Households’ resources and constraints are key components of quality of life (QOL). QOL also depends on how these are evaluated. In times of crisis one expects subjective wellbeing and quality of life to decline. We argue that the quality of life depends on objective living conditions, their subjective evaluation and the ability to maintain or improve the situation of “embedded individuals”. This ability, in turn, depends on the opportunities provided by the state, labour markets, families and communities. We analyse qualitative interviews (2008–2010) with around 25 households in precarious prosperity in two cities (Pamplona, Spain and Lausanne, Switzerland) to elaborate their QOL. Few sampled Swiss households witnessed a decline in socio-economic status, contrary to the Spanish. Domains important to these households for QOL varied according to the opportunity structures: in the Spanish sample QOL was related to the opportunities for income, work, and security to plan ahead; in the Swiss sample to health, work-life balance and loneliness. In both samples, QOL varied according to scope of agency, people’s position within the life course, the households’ past experiences, current situation and future perspectives. Lack of future perspectives and opportunities lowered QOL; reframing, adaption and accepting the situation sometimes moderated QOL. We conclude that apart from living conditions and/or subjective wellbeing, households’ agency within opportunity structures is a promising direction for further research in QOL.     

Linking somatic and symbolic representation in semantic memory: the dynamic multilevel reactivation framework

Biological plausibility is an essential constraint for any viable model of semantic memory. Yet, we have only the most rudimentary understanding of how the human brain conducts abstract symbolic transformations that underlie word and object meaning. Neuroscience has evolved a sophisticated arsenal of techniques for elucidating the architecture of conceptual representation. Nevertheless, theoretical convergence remains elusive. Here we describe several contrastive approaches to the organization of semantic knowledge, and in turn we offer our own perspective on two recurring questions in semantic memory research: (1) to what extent are conceptual representations mediated by sensorimotor knowledge (i.e., to what degree is semantic memory embodied)? (2) How might an embodied semantic system represent abstract concepts such as modularity, symbol, or proposition? To address these questions, we review the merits of sensorimotor (i.e., embodied) and amodal (i.e., disembodied) semantic theories and address the neurobiological constraints underlying each. We conclude that the shortcomings of both perspectives in their extreme forms necessitate a hybrid middle ground. We accordingly propose the Dynamic Multilevel Reactivation Framework—an integrative model predicated upon flexible interplay between sensorimotor and amodal symbolic representations mediated by multiple cortical hubs. We discuss applications of the dynamic multilevel reactivation framework to abstract and concrete concept representation and describe how a multidimensional conceptual topography based on emotion, sensation, and magnitude can successfully frame a semantic space containing meanings for both abstract and concrete words. The consideration of ‘abstract conceptual features’ does not diminish the role of logical and/or executive processing in activating, manipulating and using information stored in conceptual representations. Rather, it proposes that the materials upon which these processes operate necessarily combine pure sensorimotor information and higher-order cognitive dimensions involved in symbolic representation.
