Data and phenomena in conceptual modelling

The distinction between data and phenomena introduced by Bogen and Woodward (Philosophical Review 97(3):303–352, 1988) was meant to help accounting for scientific practice, especially in relation with scientific theory testing. Their article and the subsequent discussion is primarily viewed as internal to philosophy of science. We shall argue that the data/phenomena distinction can be used much more broadly in modelling processes in philosophy.     

„Rocken statt Ritzen“

Background

Non-suicidal self-injury (NSSI) starts in adolescence and decreases during young adulthood. Despite a high prevalence among adolescents only a few therapeutic interventions directly addressing adolescents exist.

Aim

By connecting music therapy with elements from behavioral therapy an attempt was made to create a therapeutic program which is attractive to adolescents.

Material and methods

A pilot trial of the program “Stop cutting - rock!” was conducted with 12 adolescent females with a mean age of 15.15 years (standard deviation SD ±1.34). The study aimed to compare the frequency of NSSI throughout the treatment phase as well as a pre-post comparison of depression scores.

Results

The results showed a trend towards a decreasing frequency of NSSI. Depression scores decreased significantly between the assessment before therapy and at a 3-month follow-up after the end of the therapy.

Conclusion

The positive feedback concerning music therapeutic elements points to the attractiveness of the approach. By integrating multimodal therapeutic strategies it seems possible to create an individually tailored intervention for adolescents with NSSI.     

Ferenczi and Winnicott: Why We Need Their Radical Edge: Commentary on Paper by Michael Parsons

Parsons's paper, “An Independent Theory of Clinical Technique,” is discussed. Agreement is expressed with many of the theoretical points made by Parsons, and the creative and freeing historical role of the British Independent tradition (recently attacked by Kleinian authors such as Segal) is praised. However, the author sees some of the clinical examples in the paper as expressing a traditionalist conception of psychoanalytic practice, with a strong one-sided emphasis on the analyst as a knowledgeable expert offering deep interpretations. Parsons does not question the nature of the actual intersubjective relationship in each dyad, with its fluctuations and its subtle nuances, which can go far beyond the proclaimed roles of the two partners, at times even reversing them. More radical points of view can be found in the work of Ferenczi and Winnicott, two authors who are significant both for Parsons and for the author; for example, Ferenczi's emphasis on the patient's capacity to interpret the analyst's countertransference, and the experiments with the setting both made in their search for an adaptation to the unique ‘analysand's needs. In conclusion, the paper calls for continued departure from standard techniques of any kind, critically deconstructing all traditional assumptions regarding the analytic process.     

Differential roles of the frontal and parietal cortices in the control of saccades

Although externally as well as internally-guided eye movements allow us to flexibly explore the visual environment, their differential neural mechanisms remain elusive. A better understanding of these neural mechanisms will help us to understand the control of action and to elucidate the nature of cognitive deficits in certain psychiatric populations (e.g. schizophrenia) that show increased latencies in volitional but not visually-guided saccades. Both the superior precentral sulcus (sPCS) and the intraparietal sulcus (IPS) are implicated in the control of eye movements. However, it remains unknown what differential contributions the two areas make to the programming of visually-guided and internally-guided saccades. In this study we tested the hypotheses that sPCS and IPS distinctly encode internally-guided saccades and visually-guided saccades. We scanned subjects with fMRI while they generated visually-guided and internally-guided delayed saccades. We used multi-voxel pattern analysis to test whether patterns of cue related, preparatory and saccade related activation could be used to predict the direction of the planned eye movement. Results indicate that patterns in the human sPCS predicted internally-guided saccades but not visually-guided saccades in all trial periods and patterns in the IPS predicted internally-guided saccades and visually-guided saccades equally well. The results support the hypothesis that the human sPCS and IPS make distinct contributions to the control of volitional eye movements.     

Structural Equation Modeling of Spatial Presence: The Influence of Cognitive Processes and Traits

This article examines the formation process of spatial presence, which is conceived as a two-step process involving the construction of a mental model of the mediated environment, followed by the emergence of spatial presence. During both stages, cognitive processes and user traits are in effect. We present data derived from a pooled set of data of three studies using the same virtual environment. Structural equation modeling is used to confirm the proposed theoretical model. The results show that attention and the trait of visual spatial imagery are positive predictors of the mental model of the mediated environment. In the second step, the formation of spatial presence is governed by involvement, the suspension of disbelief, and the domain-specific interest, together with the mental model.
