How do I cite an article within an article?

For example:
This is a particularly important issue to address because
the current literature on personality trait development has suggested
that not only do social role changes occur in older adulthood
but personality traits also undergo meaningful, normative
changes during the aging process (Mroczek & Spiro, 2003; Small,
Hertzog, Hultsch, & Dixon, 2003; Lucas & Donnellan, 2011;
Roberts, Walton, & Viechtbauer, 2006).
