Affective variables have been shown to impact working memory and cognitive control. Theoretical arguments suggest that the functional impact of emotion on cognition might be mediated through shifting action dispositions related to changes in motivational orientation. The current study examined the effects of positive and negative affect on performance via direct manipulation of motivational state in tasks with high demands on cognitive control. Experiment 1 examined the effects of monetary reward on task-switching performance, while Experiment 2 examined the effects of (...) both rewards and punishments on working memory, using primary (liquid) reinforcers. In both experiments, dissociable trial-by-trial and contextual (block-related) enhancements of cognitive control during task performance were observed in relationship to motivational incentive value. Performance enhancements were equivalent in the reward and punishment conditions, but were differentially impacted by individual difference measures of trait reward and punishment sensitivity. Together, the results suggest both common and specific mechanisms by which approach and avoidance motivational states influence cognitive control, via activation of reward and punishment processing systems.

This special issue of Science, Technology, & Human Values critically explores a new stage in which the life sciences and biomedical practices have entered. This new stage is marked by postgenomic developments and an increased interest of life sciences in the everyday lives of people outside laboratories and clinical settings. Furthermore, particular attention is given to many chronic and degenerative disorders such as cardiovascular disease, Alzheimer’s disease, or developmental disorders. These developments coincide—or have become entangled—with a new set of interests (...) that an anthropologically inclined science and technology studies is bringing to the analyses of biomedical practices. An increased interest is observed in the anthropologically inclined STS in studying phenomena on different scales and in exploring fields that are not readily dominated by technoscientific rationality in practice. The introduction to the special issue examines briefly these developments and situates them in a broader genealogy of different movements that have taken place in the anthropologically inclined subfield of STS since the late 1970s and early 1980s.

The problem of expertise plays a key role in current scientific and political debates. Dominant approaches to expertise are focused on knowledge as an idealistic content. Given the partial inadequacy of these perspectives, an amended theoretical and methodological approach is needed. This paper aims then at sketching a relational conceptualization of expertise. At this purpose, the connections between recent anthropological theories and pragmatist theories will be highlighted.

The article analyses practices, perceptions and political dramatizations of bone marrow donation in Cyprus. Based on empirical data from an ethnographic study on practices of organ and bone marrow transplantation in postcolonial Cyprus, forms of oppositional biopolitics are analysed that are not bound by the modern, étatist regime of governing populations but capitalize on new developments in biomedicine, on new political movements, as well as on transformations in the political sphere. These reconfigurations are interpreted as instances of an emerging bio-subpolitics (...) that transcends national borders and produces new complexities, interrelations, associations and social forms that come into being alongside biomedicine. At the same time, these developments co-produce cosmopolitan citizens and new subjectivities, transcending nationally bound regimes of political deliberation and identification. These forms of biopolitics mobilize local historical experiences and take advantage of affordances provided by biomedical platforms operating on a global scale that make available an opportunity structure for a cosmopolitan bio-subpolitics.
