Fig. 5: Resulting Factors from Exploratory Factor Analysis on Survey Data.
From: Mapping computational cognitive profiles of aging to dissociable brain and sociodemographic factors

An exploratory factor analysis on survey data revealed four factors: (1) SES & Cognitive Reserve included positive loadings for various socioeconomic measures (e.g., current perceived SES) and variables typically conferring high cognitive reserve (e.g., education and occupational complexity); (2) Cognitive & Physical Stimulation included positive loadings for engagement in cognitively and physically stimulating activities; (3) Hobbies showed positive loadings for engagement in pleasurable or leisure activities such as attending live performances and art classes; (4) Mental Health Symptoms showed positive loadings for measures of anxiety, depression, and financial worries, but negative loadings for life satisfaction and sleep quality; (5) Childhood SES depicts positive loadings primarily for participants’ perceived SES in childhood (retrospective measure). More blue = positive; more orange = negative.
