Correlations of estimated model parameters with related behavioral measures of verbal task performance in the discovery sample and picture task performance in the replication (words/pictures) sample

Model parameter	Relevant phenotype in the verbal task	Correlation, Spearman’s ρ	Relevant free recall phenotype in the picture task	Correlation, Spearman’s ρ
Learning rate α	Percentage of correctly remembered words in the immediate recall	0.722	Percentage of correctly remembered pictures	0.152
Decision threshold β	Number of mistakes in the delayed recall	−0.825	Number of mistakes in the picture recall	−0.204
Repetition-based memory improvement c	Percentage of correctly remembered words in the delayed recall	0.607	Percentage of correctly remembered pictures	0.098
Modulation by positive emotional arousal εpos	Percentage of correctly remembered positive minus neutral words in the delayed recall	0.737	Percentage of correctly remembered positive minus neutral pictures	0.133
Modulation by negative emotional arousal εneg	Percentage of correctly remembered negative minus neutral words in the delayed recall	0.708	Percentage of correctly remembered negative minus neutral pictures	0.074

Correlations with verbal task performance are quite high because computational modeling was performed for the verbal task. Correlations with picture task performance suggest that the percentage of correctly remembered pictures in the free recall is related more to the learning rate α than to the repetition-based memory improvement c and hence is used for the replication of gene sets associated with α. All correlations are statistically significant.
