Effects of biasing on the threshold-unit’s activation. (A,B) Constant additive biasing of the accumulator can dramatically decrease response times for a fixed level of stimulus strength [offsets of stimulus-locked traces, (A)] and slightly modulates the initial rise period of the activation [slight changes in response-locked traces (B)]. (C–G) Constant additive biasing of the threshold-unit also affects stimulus-locked response times (C) and dramatically modulates the duration of the initial rise in response-locked averages (D). (E–G) Three different levels of biasing (shifts of the initial input level denoted by the colored circle) with colors corresponding to the traces in (C) and (D) blue = low bias; green = medium bias; red = high bias.
