Domestic dogs comprehend human communication with iconic signs

A key skill in early human development is the ability to comprehend communicative intentions as expressed in both nonlinguistic gestures and language. In the current studies, we confronted domestic dogs (some of whom knew many human ‘words’) with a task in which they had to infer the intended referent of a human's communicative act via iconic signs – specifically, replicas and photographs. Both trained and untrained dogs successfully used iconic replicas to fetch the desired item, with many doing so from the first trial. Dogs’ ability to use photographs in this same situation was less consistent. Because simple matching to sample in experimental contexts typically takes hundreds of trials (and because similarity between iconic sign and target item did not predict success), we propose that dogs’ skillful performance in the current task reflects important aspects of the comprehension of human communicative intentions.     

Ambulante Psychotherapie bei Kindern und Jugendlichen

This paper presents the results of a study of the state of outpatient psychotherapy of children and juveniles in Germany after the PTG came into force. A total of 180 psychotherapists were questioned on certain issues. One result was that patients have to wait 4.5 months for psychotherapy and that every second patient asking for a diagnostic interview and possible treatment was refused.Of those who were given a diagnostic interview 43% were not taken into treatment, although disturbances were diagnosed such as addiction, bodily disabilities with psychic complications, enuresis/encopresis, anorexia nervosa, psychosomatic illnesses, developmental arrests which would normally demand psychotherapeutic treatment. Furthermore only 25% of those children and juveniles who Löcherbach et al. (2000, S.59 f.) considered needing and wanting psychotherapeutic treatment were actually in a G IV psychotherapy.Apart from this the possibility of getting psychotherapy as well as the kind of psychotherapy proved to be dependent on the kind of medical insurance. Differing payments by the insurance companies caused longer waiting times for patients and determined the choice of psychotherapy by the psychotherapists.     

Wissenschaftliche Prüfung und wissenschaftliche Anerkennung psychotherapeutischer Verfahren

The authors focus on the following questions: firstly, what anthropological preconceptions lie behind the nomological scientific viewpoints adopted by the scientific advisory board “psychotherapy”, secondly, to what extend a general efficacy of psychotherapy can be verified using the criteria it proposes. The authors demonstrate that in the proposed testing procedure humans are conceptualized as beings without consciousness and subjectivity. Furthermore, nomologically designed investigations cannot verify a general efficacy of new forms of psychotherapy, nor could they verify the general efficacy of those psychotherapeutic methods already approved by the insurance companies.     

Multidimensional Cross-Recurrence Quantification Analysis (MdCRQA) – A Method for Quantifying Correlation between Multivariate Time-Series

In this paper, Multidimensional Cross-Recurrence Quantification Analysis (MdCRQA) is introduced. It is an extension of Multidimensional Recurrence Quantification Analysis (MdRQA), which allows to quantify the (auto-)recurrence properties of a single multidimensional time-series. MdCRQA extends MdRQA to bi-variate cases to allow for the quantification of the co-evolution of two multidimensional time-series. Moreover, it is shown how a Diagonal Cross-Recurrence Profile (DCRP) can be computed from the MdCRQA output that allows to capture time-lagged coupling between two multidimensional time-series. The core concepts of these analyses are described, as well as practical aspects of their application. In the supplementary materials to this paper, implementations of MdCRQA and the DCRP as MatLab- and R-functions are provided.

Is a Stage Model a Useful Approach to Explain Car Drivers' Willingness to Use Public Transportation?

The paper empirically evaluates the utility of a stage approach in describing car drivers' decisions to change to public transportation. Data from 2 samples are used to test whether 5 subgroups assumed to represent an ordered sequence of decision stages derived from an extended version of the model of action phases ( Gollwitzer, 1996 ) is clearer than the changed one. Contrary to expectations, cluster analysis indicates that a 4-cluster solution is most adequate. Whereas the profiles of 3 clusters fit the expected features of the precontemplation, contemplation, and maintenance stages, the existence of separated preparation and action stages was not confirmed. Evidence was also mixed for the assumption that the assignment to the decision stages can be predicted by specific motivational variables.     

Word form access dyslexia: understanding the basis of visual reading errors

We report the case of a patient V.E.M. who exhibits the infrequently described syndrome of visual dyslexia. V.E.M. read many single words accurately and rapidly; however, when words were read inaccurately, the majority of responses were alternate real words bearing a strong visual relationship to the target items. A series of observational and experimental investigations of her reading skills revealed that response accuracy was strongly affected by word frequency and mildly affected by concreteness but not influenced by word length, orthographic neighbourhood size, or semantic priming. It is argued that V.E.M.'s visual dyslexia results from a deficit of the visual word form system. More specifically, we propose that this deficit has an “access” quality, with visual word form representations remaining relatively intact despite an impairment in the processes by which these representations are activated. Taking the results of this study together with previous reports of dyslexic patients who make a high proportion of visual paralexic errors, we also suggest that visual dyslexia represents a multicomponent dyslexic syndrome for which phonological impairment and not semantic impairment may be a necessary condition.
