This paper provides five clear, relatable examples that can help students understand the distinction between the term "factors" and "mechanisms" in Developmental Psychology. The examples emphasize the idea that factors are related to changes in ways that moderate development, but are not causal. On the other hand, the term mechanism refers to processes that produce change. These examples can be embedded in lectures individually or shared as a whole to support student learning. A precise understanding of the distinction between factors and mechanisms can help students better understand development, parse research findings, and consider policy and practical implications.
