Meditation experience is associated with increased cortical thickness

Abstract: Previous research indicates that long-term meditation practice is associated with altered resting electroencephalogram patterns, suggestive of long lasting changes in brain activity. We hypothesized that meditation practice might also be associated with changes in the brain’s physical structure. Magnetic resonance imaging was used to assess cortical thickness in 20 participants with extensive Insight meditation experience, which involves focused attention to internal experiences. Brain regions associated with attention, interoception and sensory processing were thicker in meditation participants than matched controls, including the prefrontal cortex and right anterior insula. Between-group diierences in prefrontal cortical thickness were most pronounced in older participants, suggesting that meditation might oiset age-related cortical thinning. Finally, the thickness of two regions correlated with meditation experience. These data provide the ¢rst structural evidence for experience-dependent cortical plasticity associated with meditation practice. NeuroReport 16:1893^1897 � c 2005 Lippincott Williams & Wilkins.

Pain catastrophizing: a critical review

Abstract: Pain catastrophizing is conceptualized as a negative cognitive–affective response to anticipated or actual pain and has been associated with a number of important pain-related outcomes. In the present review, we first focus our efforts on the conceptualization of pain catastrophizing, highlighting its conceptual history and potential problem areas. We then focus our discussion on a number of theoretical mechanisms of action: appraisal theory, attention bias/information processing, communal coping, CNS pain processing mechanisms, psychophysiological pathways and neural pathways. We then offer evidence to suggest that pain catastrophizing represents an important process factor in pain treatment. We conclude by offering what we believe represents an integrated heuristic model for use by researchers over the next 5 years; a model we believe will advance the field most expediently.

Clothes Make the Person? The Tailoring of Legitimating Accounts and the Social Construction of Identity

Abstract: We empirically explore the legitimating accounts for and against policies precluding workplace discrimination against gay, lesbian, bisexual, and transgender people, focusing on how agents working at both the national level and within organizations use broader cultural accounts in building their legitimating accounts in local settings. The diffusion perspective in institutional theory has portrayed how agents import 'ready-to-wear' cultural accounts. In contrast, translation theory depicts how agents interpret and adapt cultural accounts as they fashion them into legitimating accounts for a local setting. An alternative would theorize accounts that are neither strictly borrowed nor idiosyncratically tailored. We advanced a third perspective, drawing on frame analysis as it is used in social movement theory. Framing theory attends to both the importance of cultural building blocks and the embedded ways in which agents relate to and shape systems of meaning and mobilize collective action to change social arrangements. We find that legitimating accounts are intertwined with the construction of social identities, which serve to legitimate, on the one hand, an account maker's participation in the discourse and set of claims, and on the other hand, the involvement of proponents and crucial audiences. We suggest that the mobilizing potential of legitimating accounts rests in part on their messages becoming 'autocommunicational,' so that listeners identify themselves with the message.
