Fig. 4.

Distribution of measured activation level around RT (A_RT) between trials in a randomly selected accumulator as a function ensemble size (N), termination rule (p_N), and accumulation rate correlation (r_v). The x axis ranges from 10⁰ to 10³, and the y axis ranges from 10² to 10³. Other conventions as in Fig. 2. Individual threshold (θ, red line) was identical across accumulators. Thus, correspondence between A_RT and θ is indicated by overlap of distributions (black lines) and threshold (red line).
