Fig. 3

Group and sex differences on the circular standard deviation (CSD) in several set sizes and on the VP model parameters. The CSD represents the visual memory precision of the subjects, and the larger the CSD, the worse the memory precision. Males showed higher CSD than females at all levels of set size, and MDD showed higher CSD than HC at set size 2, 4, and 6 but not at set size 1 (A). Females have more initial resources than males (B). MDD has larger resource allocation variability than HC (D). No significant group differences or sex differences in decaying exponent and choice variability(C & E). Note: ∗ represents significant differences between the groups or sexes, and the error bars represent the error deviations
