Effects of practice on task architecture: Combined evidence from interference experiments and random-walk models of decision making
Does extensive practice reduce or eliminate central interference in dual-task processing? We explored the reorganization of task architecture with practice by combining interference analysis (delays in dual-task experiment) and random-walk models of decision making (measuring the decision and non-de...
