Task design and behavioral evidence. A, Trial structure of the visual and semantic liking-rating tasks. B, Trial structure of the Korean learning task. C, Performance over time in the Korean learning task. Error bar indicates SEMs. D, Trial structure of the fMRI valuation task. E, Estimated individual coefficients for a linear regression of stimulus values on visual and semantic ratings. Each individual is represented by a point. Semantic–visual trials only. Green and orange lines present mean β coefficients. Visual and semantic ratings were normalized to a −1.5 to 1.5 scale. F, Estimated individual coefficients for the visual attribute in a similar linear regression, estimated separately by condition. The dotted line represents a 45° line. G, Scatter plot summarizing the results of the test–retest correlations of semantic and visual ratings. H, Histogram of semantic and visual ratings.
