“…Increases in drift rates in a race model could indicate an urgency signal, implemented by drift gain modulation, with qualitatively similar effects to collapsing thresholds over the course of a decision (Cisek et al, 2009; Hawkins et al, 2015; Miletić, 2016; Miletić and Van Maanen, 2019; Murphy et al, 2016; Thura and Cisek, 2016; Trueblood et al, 2020; van Maanen et al, 2019). In cognitively demanding tasks, it has been shown that two distinct components of evidence accumulation (quality and quantity of evidence) are affected by SAT manipulations, with quantity of evidence being analogous to an urgency signal (Boag et al, 2019b, 2019a). Recent evidence suggests that different SAT manipulations can affect different psychological processes: cue-based manipulations that instruct participants to be fast or accurate, lead to overall threshold adjustments, whereas deadline-based manipulations lead to a collapse of thresholds (Katsimpokis et al, 2020).…”
