“…We examined six foundational signatures of human perceptual decision making that have already been established in studies of 2-choice tasks: 1) Human decisions are stochastic, meaning that the same stimulus can elicit different responses on different trials (Beck, Ma, Pitkow, Latham, & Pouget, 2012; Renart & Machens, 2014), 2) increasing speed stress shortens RT but decreases accuracy (speed-accuracy trade-off) (Forstmann et al, 2016; Heitz, 2014; Heitz & Schall, 2012), 3) more difficult decisions lead to reduced accuracy and longer RT (Forstmann et al, 2016; Ratcliff & Rouder, 1998; Wagenmakers & Brown, 2007), 4) RT distributions are right-skewed, and this skew increases with task difficulty (Forstmann et al, 2016), 5) RT is lower for correct than for error trials (Brown & Heathcote, 2008; Forstmann et al, 2008; Luce, 1986; Ratcliff, 2002; Wagenmakers & Brown, 2007), and 6) confidence is higher for correct than for error trials (Rahnev, 2021). For each of these signatures, we confirmed that the signature also occurs for our 8-choice task with naturalistic images, and then tested whether RTNet and Anytime Prediction exhibit the same signature.…”
