Procedure for estimating subjective cue selection. A, Subjective cue selection (identifying the SRC vs the non-SRC). i, The cue–choice association history reflects each participant's subjective estimate of cue–outcome association. ii, iii, The number of associations between each cue and each choice were, therefore, tallied and discounted with recency-weighted factor of a half-life of six trials (ii) and used to create (iii) β functions (mean value indicated by green lines) summarizing estimates of the subjective strengths of association between each cue and each outcome. iv, These estimates were then compared with the actual choice in the current trial (Trial N). The SRC (shown in red), as opposed to the non-SRC (shown in green), can then be inferred as the cue that was more likely to have guided the participant's choice on the current trial. B, In summary, on each trial, we were able to define the cue that better predicted the subject's current choice as the SRC and the other cue as the non-SRC.
