p334fig08.60 Behavioral data (left image) and simulation (right image) about accuracy in both the RT and FD tasks.  See text for details<BR>||  Behavioral data: % correct vs % coherence (Mazurek etal 2003; Roltman, Shadien 2002).  More coherence in the motion causes more accurate decisions.  RT task accuracy at weaker coherence levels is slightly better than FD task accuracy.
