Erikson's seventh psychosocial stage — generativity vs. stagnation — and the psychology of middle adulthood. We cover primary vs. secondary aging, fluid vs. crystallized intelligence, Schaie's stages of adult cognitive development, and whether the 'midlife crisis' is actually supported by research. Built for psych undergrads studying lifespan development. #psychology #psychologyundergrad #psychstudent #developmentalpsychology #erikson #generativity #middleadulthood
