Figure 3.

Model-estimated memory trajectories as a function of contact frequency with social network members other than spouses. Level differences reflect the finding that greater contact frequency was associated with higher initial memory. Non-parallel lines reflect the finding that greater contact frequency was associated with slower subsequent rate of memory decline. Depicted intercepts and slopes control for all other variables in the model (i.e., age, gender, race, ethnicity, education, baseline year, marital status, social network size, social support, and social strain).
