Crossmodal interaction between the mental number line and peripersonal haptic space representation in sighted and blind individuals

Humans tend to represent numbers in the form of a mental number line. Here we show that the mental number line can modulate the representation of peripersonal haptic space in a crossmodal fashion and that this interaction is not visually mediated. Sighted and early-blind participants were asked to haptically explore rods of different lengths and to indicate midpoints of those rods. During each trial, either a small (2) or a large (8) number was presented in the auditory modality. When no numbers were presented, participants tended to bisect the rods to the left of the actual midpoint, consistent with the notion of pseudoneglect. In both groups, this bias was significantly increased by the presentation of a small number and was significantly reduced by the presentation of a large number. Hence, spatial shifts of attention induced by number processing are not limited to visual space or embodied responses but extend to haptic peripersonal space and occur crossmodally without requiring the activation of a visuospatial representation.

Long-term self-monitoring of weight: a case study

The aim of this study was to examine the self-monitoring of weight on a daily basis over a long period of time in order to understand the process of weight regain. An obese female client measured her weight every morning over a period of 10 years. The subject made a total of 2081 weight measurements. Thus, her weight was measured on 67% of all possible days. After the initial weight loss a pattern of gradual weight gain was observed. The subject gained weight during August and September, and at the end of December, in particular. Furthermore, her weight increased slightly at the weekends. This case study highlights the advantage of self-monitoring of weight on a daily basis. Individual patterns of weight change possibly associated with season and weekly variation may be crucial when obese subjects try to maintain their weight after weight loss. However, it may take several months or even years to detect the weekly and yearly rhythms or other patterns in the data. Thus, self-control of weight is problematic, since patterns in the weight regain process are difficult to detect. This may be one reason why self-control of weight is so difficult.     

Narrative Understanding in Acute Psychosis

Hermeneutical premises are adequate in understanding the psychotic patient. It is more important to hear and try to understand the patient's story told by the latter as an equal partner in conversation than understand events through stories in which the meanings are already determined. Understanding is dependent on the unique way in which the feelings, thoughts, and actions of the patient are connected with those of the ward staff, i.e., mutual knowledge. In this way understanding conforms to the preunderstanding of the interpreter as well as adequately captures the intentions of its originator. These are the preconditions for the integration of the need-adapted approach to the treatment of schizophrenia.     

The social concept of disease

In the discussion of such social questions as “how should alcoholics be treated by society?” and “what kind of people are responsible in the face of the law?”, is “disease” a value-free or value-laden notion, a natural or a normative one? It seems, for example, that by the utterance ‘alcoholism should be classified as a disease’ we mean something like the following: the condition called alcoholism is similar in morally relevant respects to conditions that we uncontroversially label diseases, and therefore we have a moral obligation to consider alcoholism a disease. So there are grounds to think that, in the discussion of social questions, our concept of disease is strongly value-laden. However, it does not follow that the medical concept of disease is likewise value-laden. In this paper I distinguish between the medical and social concepts of disease, arguing that the naturalist-normativist debate is concerned with the former, but not the latter. Therefore, we need not settle the naturalist-normativist debate in order to conclude that the social concept of disease is value-laden.
