Figure 1. Design of 2-by-2 experiment (experiment 1).

Figure 1

(A) 2-by-2 factorial design (visual cue and juice reward). All event types (fixation, uncued reward, cue, cue-reward) were equiprobable. (B) Timing of an individual cue-reward trial. The timing of the juice reward and the visual cue were the same in the uncued reward and cue trials, respectively. See also Table S1 and Figure S1.
