“…Researchers have also investigated the constraints that underlie grasp posture planning in tasks that require the use of both hands (Fischman, Stodden, & Lehman, 2003;Hughes & Franz, 2008;Hughes, Haddad, Franz, Zelaznik, & Ryu, 2011;Hughes, Reißig, & Seegelke, 2011;Hughes, Seegelke, Reißig, & Schütz, 2012;van der Wel & Rosenbaum, 2010;Weigelt, Kunde, & Prinz, 2006). Bimanual object manipulation tasks provide an excellent opportunity to examine how goal-directed planning constraints (end-state comfort) interact with the preference toward spatial coupling.…”
