This title has ceased (2018).Socioaffective Neuroscience & Psychology is a peer reviewed open access journal that aims to stimulate multidisciplinary research into the central nervous system and its complex relationship with the surrounding social environment. Spurred by significant methodological and theoretical advances in cognitive and developmental neurosciences over the past two decades, two particular fields have emerged: (i) social neuroscience focusing on the role of the brain in processing social information, and (ii) affective neuroscience focusing on the role of the brain and how it reacts to emotionally, motivationally and other affectively related inputs. Several interesting topics are now appearing as these two fields begin to overlap, for example the question of the neural processing of emotional information conveyed by congeners, and the role of the brain in functional contexts involving dyadic interactions. In particular, during the last years, developmental research has allowed us to better understand psychological and neural processes involved in early social interactions.
