A longitudinal study of pain sensitivity and blood pressure in adolescent boys: results from a 5-year follow-up.

A growing literature has observed a significant reduction in pain sensitivity among hypertensive animals and humans. It is uncertain whether a reduced sensitivity to pain can be observed in nonnotensive individuals who go on to develop high blood pressure. Blood pressure (BP) was reassessed in one hundred fifteen 19-year-old boys initially tested at age 14, when they were also presented with a pain stimulus (mechanical finger pressure). Hierarchical regression analyses indicated that information regarding pain tolerance improved prediction of changes in systolic and diastolic blood pressure beyond that afforded by differences in BP at age 14, parental history of hypertension, and body mass index. These analyses suggest that pain sensitivity may be associated with physiological processes involved in the development of sustained high blood pressure.     

Attitudes,Tracing, and Control

There is an apparent tension in our everyday moral responsibility practices. On the one hand, it is commonly assumed that moral responsibility requires voluntary control: an agent can be morally responsible only for those things that fall within the scope of her voluntary control. On the other hand, we regularly praise and blame individuals for mental states and conditions that appear to fall outside the scope of their voluntary control, such as desires, emotions, beliefs, and other attitudes. In order to resolve this apparent tension, many philosophers appeal to a tracing principle to argue that agents are morally responsible (only) for those attitudes whose existence can be traced back, causally, to a voluntary action or omission in the past. My aim in this article is to critically evaluate this tracing strategy and to argue that it gives us a misguided picture of when and why we are morally responsible for our attitudes. I argue that we should accept a ‘judgment sensitivity’ condition of moral responsibility rather than a ‘voluntary control’ condition, and defend this account against various objections.     

SOCIAL CLASS PERCEPTION AND SOCIAL STATUS AMONG SWEDISH YOUTH

Social class perception (identification) was studied as a function of ‘objective’ status (socioeconomic level) and class (occupational class) using a sample of Swedish high school students. Confirming the two minor hypotheses, the results disclosed that class perception was affected by both the ‘objective’ class and status of the subject: the manual occupational class, and those with low socioeconomic status, had in general a higher proportion of working-class identification than the nonmanual class, and those with low socioeconomic status, respectively. However, the major hypothesis, an interaction hypothesis stating that manuals are not affected by status in their class perceptions, was not confirmed. The results are discussed in the context of social psychological theory and earlier empirical research.
