Model-estimated memory trajectories as a function of marital status. Level differences reflect the finding that being married/partnered was associated with higher initial memory. Non-parallel lines reflect the finding that being married/partnered 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, social network size, contact frequency, social support, and social strain).
