“…Accompanying these developments is a burst of new thinking in the literature, reminiscent of earlier thrusts in theory development that culminated in the publication of The Psyche and the Social World (Brown and Zinkin, 1994). Contemporary developments include recent attention to social change (Rohr, 2014;Blackwell, 2014;Nitsun, 2015), the publication of comprehensive overviews of the group-analytic field interlinking theory and practice (Schlapobersky, 2016), the development of a group-analytic dictionary, and scholarly research into Foulkes' background and past influences as well as the ever-deepening roots of group analysis (Nitzgen, 2011;Lavie, 2011;Weegmann, 2011). We see a more confident and coherent location of group analysis in the relational frame (Friedman, 2014;Weegmann, 2014) and an extension of the group-analytic discourse into grappling with the core but ill-defined Foulkesian concepts of the social unconscious and the foundation matrix (Hopper and Weinberg, 2011;Scholtz, 2014).…”
