Temperament is defined as a pattern of behaviors that remain stable and show continuity over time and across different contexts (Clarke & Boinski, 1995). These behavioral patterns can be observed early in life, and can serve as a predictor of future behaviors (Weinstein & Capitanio, 2008). Temperamental differences are largely a result of interaction effects between genetic and environmental factors. These interactions can be complex, and there is a great need to better understand the nature of those interactions (Clarke & Boinski, 1995). The purpose of this project (which is still ongoing) is to better understand the features of early rearing environments that have a large impact on observed temperamental differences. Because temperament acts as a foundation for future behavior, it is important to understand the impact of early rearing environments on predicting future behavior.
