Figure 4. (Opposite) Age-related increase in memory performance. A. Means (+ SE) of z-scores for accuracy (top panel) and speed (bottom panel) for females (dark blue bars) and males (light blue bars) across the sample on each behavioral domain. ABF, abstraction and mental flexibility; ATT, attention; WM, working memory; VME, verbal memory; FME, face memory; SME, spatial memory; LAN, language reasoning; NVR, nonverbal reasoning; SPA, spatial processing; EMI, emotion identification; EMD, emotion differentiation; AGD, age differentiation; SM, sensorimotor speed; MOT, motor speed. B. Means (+ SE) of z-scores for accuracy (top panel) and speed (bottom panel) for females (dark blue bars) and males (light blue bars) on episodic memory tasks. The results are shown by age groups and correlations with age are provided by sex (bold correlations are significant at P<.001). Reproduced from ref 20: Gur RC, Richard J, Calkins ME, et al.
