This study reports results from the first International Body Project (IBP-I), which surveyed 7,434 individuals in 10 major world regions about body weight ideals and body dissatisfaction. Participants completed the female Contour Drawing Figure Rating Scale (CDFRS) and self-reported their exposure to Western and local media. Results indicated there were significant cross-regional differences in the ideal female figure and body dissatisfaction, but effect sizes were small across high-socioeconomic-status (SES) sites. Within cultures, heavier bodies were preferred in low-SES sites compared to high-SES sites in Malaysia and South Africa (ds = 1.94-2.49) but not in Austria. Participant age, body mass index (BMI), and Western media exposure predicted body weight ideals. BMI and Western media exposure predicted body dissatisfaction among women. Our results show that body dissatisfaction and desire for thinness is commonplace in high-SES settings across world regions, highlighting the need for international attention to this problem.

There are no exact boundaries of what constitutes Central Europe, but it is nevertheless very evident as a zone of interloping forces stretching across Europe. The result has been negotiated, conflictual and contested processes defining an essentially virtual, discursive, yet also actually existing, space of ‘Central Europe’. Yet, and this is the particular message of this collection of essays, ‘transition’ has not merely been a process ‘on the ground’ as object of investigation and discussion, but has also affected the observers, especially academic commentators and analysts – both within Central Europe, but also outside. This includes a growing interaction between discussions and analyses ‘inside’ and ‘outside’ Central Europe on the phenomenon of ‘transition’. The result has been mutual learning processes and changes of ways of looking at things and interpreting them. The book is divided into two parts, roughly reflecting the two key research questions.The first part (A) is devoted to transitions in regional science. Part B focuses on changes in variety of territorial structures and developmentissues caused by Central-European transitions and which are resulting in differential pathways of regional development in the region.

The ability to learn new tasks rapidly is a prominent characteristic of human behaviour. This ability relies on flex- ible cognitive systems that adapt in order to encode temporary programs for processing non-automated tasks. Previous functional imaging studies have revealed distinct roles for the lateral frontal cortices (LFCs) and the ven- tral striatum in intentional learning processes. However, the human LFCs are complex; they house multiple dis- tinct sub-regions, each of which co-activates with a different functional network. It remains unclear how these LFC networks differ in their functions and how they coordinate with each other, and the ventral striatum, to support intentional learning. Here, we apply a suite of fMRI connectivity methods to determine how LFC networks activate and interact at different stages of two novel tasks, in which arbitrary stimulus-response rules are learnt either from explicit instruction or by trial-and-error. We report that the networks activate en masse and in synchrony when novel rules are being learnt from instruction. However, these networks are not homogeneous in their functions; instead, the directed connectivities between them vary asymmetrically across the learning timecourse and they disengage from the task sequentially along a rostro-caudal axis. Furthermore, when negative feedback indicates the need to switch to alternative stimulus–response rules, there is additional input to the LFC networks from the ventral striatum. These results support the hypotheses that LFC networks interact as a hierarchical system during intentional learning and that signals from the ventral striatum have a driving influence on this system when the internal program for processing the task is updated.
