From the brain to the field: The applications of social neuroscience to economics, health, and law
Social neuroscience aims to understand the biological systems that underlie peopleâs thoughts,
feelings and actions in light of the social context in which they operate. Over the past few decades,
social neuroscience has captured the interest of scholars, practitioners, and experts in other disciplines,
as well as the general public who more and more draw upon the insights and methods of social
neuroscience to explain, predict and change behavior. With the popularity of the field growing, it has
become increasingly important to consider the validity of social neuroscience findings as well as what
questions it can and cannot address. In the present review article, we examine the contribution of social
neuroscience to economics, health, and law, three domains with clear societal relevance. We address
the concerns that the extrapolation of neuroscientific results to applied social issues raises within each
of these domains, and we suggest guidelines and good practices to circumvent these concerns

Jumping on the 'badwagon'? How group membership influences responses to the social exclusion of others
In four studies, we addressed whether group membership influences behavioral and neural responses to the social exclusion of others. Participants played a modified three-player Cyberball game (Studies 1-3) or a team-selection task (Study 4) in the absence or presence of a minimal group setting. In the absence of a minimal group, when one player excluded another player, participants actively included the excluded target. When the excluder was from the in-group and the excluded player from the out-group, participants were less likely to intervene (Studies 1-3), and also more often went along with the exclusion (Study 4). fMRI results (Study 3) showed that greater exclusion in the minimal group setting concurred with increased activation in the dlPFC, a region associated with overriding cognitive conflict. Self-reports from Study 4 supported these results by showing that participants' responses to the target's exclusion were motivated by group membership as well as participants' general aversion to exclude others. Together, the findings suggest that when people witness social exclusion, group membership triggers a motivational conflict between favoring the in-group and including the out-group target. This underscores the importance of group composition for understanding the dynamics of social exclusion
Investigation of Turbulence Parametrization Schemes with Reference to the Atmospheric Boundary Layer Over the Aegean Sea During Etesian Winds
The spatial structure of the marine atmospheric boundary layer (MABL) over the Aegean Sea is investigated using the Weather Research and Forecasting (WRF) mesoscale model. Two âfirst-orderâ non-local and five â1.5-orderâ local planetary boundary-layer (PBL) parametrization schemes are used. The predictions from the WRF model are evaluated against airborne observations obtained by the UK Facility for Airborne Atmospheric Measurements BAe-14 research aircraft during the Aegean-GAME field campaign. Statistical analysis shows good agreement between measurements and simulations especially at low altitude. Despite the differences between the predicted and measured wind speeds, they reach an agreement index of 0.76. The simulated wind-speed fields close to the surface differ substantially among the schemes (maximum values range from 13 to (Formula presented.) at 150-m height), but the differences become marginal at higher levels. In contrast, all schemes show similar spatial variation patterns in potential temperature fields. A warmer (1â2 K) and drier (2â3(Formula presented.) layer than is observed, is predicted by almost all schemes under stable conditions (eastern Aegean Sea), whereas a cooler (up to 2 K) and moister (1â2(Formula presented.) layer is simulated under near-neutral to nearly unstable conditions (western Aegean Sea). Almost all schemes reproduce the vertical structure of the PBL and the shallow MABL (up to 300 m) well, including the low-level jet in the eastern Aegean Sea, with non-local schemes being closer to observations. The simulated PBL depths diverge (up to 500 m) due to the different criteria applied by the schemes for their calculation. Under stable conditions, the observed MABL depth corresponds to the height above the sea surface where the simulated eddy viscosity reaches a minimum; under neutral to slightly unstable conditions this is close to the top of the simulated entrainment layer. The observed sensible heat fluxes vary from â40 to (Formula presented.), while the simulated fluxes range from â40 to (Formula presented.); however, all of the schemesâ predictions are close to the observations under unstable conditions. Finally, all schemes overestimate the friction velocity, although the simulated range (from 0.2 to (Formula presented.) is narrower than that observed (from 0.1 to (Formula presented.).</p
