Are Animals Capable of Concepts?

Often, the behavior of animals can be better explained and predicted, it seems, if we ascribe the capacity to have beliefs, intentions, and concepts to them. Whether we really can do so, however, is a debated issue. Particularly, Donald Davidson maintains that there is no basis in fact for ascribing propositional attitudes or concepts to animals. I will consider his and rival views, such as Colin Allen's three-part approach, for determining whether animals possess concepts. To avoid pure theoretical debate, however, I will test these criteria using characteristic examples from ethology that depict a broad range of animal behavior. This will allow us to detect a series of gradations in animals' capacities, in the course of which we can think over what would count for or against an attribution of concepts and propositional attitudes to them in each single case. Self-conceit is our natural hereditary disease. Of all creatures man is the most wretched and fragile, and at once the most supercilious. ... It is by this conceit that man arrogates to himself ... divine properties, that he segregates himself from the mass of other creatures and raises himself above them ...

Visual stream Segregation

A visual analog of auditory stream segregation occurs when a dot moving in discrete, jumps, alternates between positions on two regular trajectories. At slow speeds, one dot in irregular motion is seen. At higher speeds, two dots are seen, each moving in a regular trajectory.     

Pavlovian conditioning with proximal stimuli

This experiment was conducted with the objective of demonstrating that the effective stimuli in Pavlovian Conditioning are not environmental stimuli but internal physiological processes elicited by environmental input (proximal stimuli). In order to achieve the objective, afterimages in color vision were used: looking at a diffuse lightened circle after seeing a red circle yields an image of a green circle. A differential conditioning paradigm with two sequential compounds was run. In one group (G⁺B^?: n₁=10), a red circle followed by a green circle was paired with shock, whereas a red circle followed by a blue circle remained unpaired. A second group (G^?B⁺: n₂=10) received red-blue paired trials and unpaired red-green trials. Immediately after that training, subjects were tested with a new, never trained sequential compound: a red circle followed by a diffuse lightened circle. Furthermore, they were tested with the already trained compounds. Taking the environmental point of view, the never trained stimulus should elicit an orienting response lying inbetween the excitatory reaction to the paired stimulus and the inhibitory reaction to the unpaired stimulus. From the proximal point of view, the diffuse light should elicit an excitatory reaction in group G⁺B^? and an inhibitory reaction in group G^?B⁺. Electrodermal conditioned anticipatory and omission responses were measured. The results supported the proximal hypothesis. Hence, defining input in environmental terms may be the wrong way. Instead, in conceptualizing the stimulus in conditioning, the following should be considered: the processing organism itself is creating the effective stimuli.     

Dreidimensionales Körperbild in der Psychodiagnostik

The body sculpture technique is a procedure in which patients create a three-dimensional model of their own body with modelling clay. This existing technique has been further developed into the modular body sculpture technique and offers a diagnostic approach to the body image. After an introduction in the conceptual foundations of body self-representation the technique is described. Using a case study, advantages for clinical applications are illustrated. Contributions of this technique to a deeper understanding of the structure of body memory are discussed in the context of current cognitive theories.     

Subtly offending feedback

Providing acceptable negative feedback is difficult because it may threaten the receiver's self‐esteem. Studies have established that destructive feedback elicits stronger negative reactions than constructive feedback. However, these destructive conditions were quite strong, implying a clear threat to the self. Because of the importance of protecting one's self‐concept, negative evaluations might be provoked by more subtle cues. Such cues should also be detected by observers. We developed three variants of subtly offending feedback in which mistakes appeared disproportionately serious. In an experimental pilot study, 132 student observers judged the fairness of feedback given to another student. The subtly offending conditions were evaluated as less fair than constructive feedback but as more fair than destructive feedback.     

Psychosoziale Interventionen bei Patientinnen mit Brustkrebs

Breast cancer patients are subject not only to physical strain but also to substantial psychological and social stress as well as major threats and challenges.The paper presented gives an overview of the research status on psychosocial interventions to support patients in their coping endeavours.Psychosocial basic care of women with breast cancer is performed by the physicians treating oncologically and includes information fitting patients' information needs,and responding to their emotional stress.Evaluated training and educational programs are available for physicians to enhance their psychosocial competence.Psychosocial basic care is completed by psychoeducational interventions.In 20–30% of women with breast cancer, there is a need for a special psychotherapeutic treatment.Especially, supportive and cognitive-behavioral therapies in an individual or a group setting contribute to a reduction of anxiety and depression. Even anticipated side-effects of somatic treatments can be diminished by psychotherapy. Research in the field supports that there is a need for broad integration of psychosocial interventions into disease management programs for women suffering from breast cancer.

Lack of Detachment and Impaired Sleep Connect Perceived Unfairness with Health Complaints: a Population-Based Mediation Test

In a sample of 8223 working individuals, representative for Swiss employees, a lack of detachment from daily problems and sleep problems were tested to mediate the association between experienced unfairness in life and health problems. Mediation was compared with respect to the life domain of unfairness (work life or private life), sex and age (ages 18 to 45 and older than 45). Unfairness at work and private unfairness were tested separately with mutual control of other domains of unfairness. In an analysis of overall unfairness in life, unfairness in both domains was summed up. Both life domains of unfairness were related directly and indirectly with health problems. All indirect paths were significant. The sum of unfairness at work and unfairness in private life showed the strongest direct and indirect association with health problems. Sleep problems turned out to be a stronger mediator than lack of detachment. Differences in mediation between men and women were not significant. Sleep problems were a significantly stronger mediator in older, compared with younger, individuals. Sleep problems seem to connect experienced unfairness at different life domains with health impairments. The study adds knowledge to the health-related interplay of work, leisure, and sleep.
