Results from the LATER model. (a) Information weights for the different model fits when each of the three parameters was allowed to differ across conditions. Values represent the mean weight with 95% confidence intervals across 100 Bootstrap samples. Each row (consistent with b) represents a different participant. For both participants, the \({\theta }_{0}\) parameter, baseline level, was best in describing differences across conditions. (b) Reciprobit plots of single-trial latency distributions to the highly (dark colors) and the less rewarded target (brighter colors) when choice-trials were present (right column; orange/red colors) or absent (left column; blue colors). Each row represents a different participant. Dashed lines are model fits for the high (bright gray) and low reward (dark gray). Dots indicate which marker is used to plot the \({\theta }_{0}\) parameters in (c). (c) Scatterplot of baseline levels, \({\theta }_{0}\), for the different conditions obtained by the model fit. Values represent the mean with 95% confidence intervals across 100 Bootstrap samples. Participants can be told apart by open or filled symbols (same as in b). With choice-trials present (orange circles), baseline levels for less rewarded single-trial targets were strongly reduced.
