Abstract
Developmental theories have emphasized that motivational selectivity – focusing on a few goals instead of “wanting it all” – regulates development in individuals, dyads, or groups. We provide first evidence that this motivational strategy predicts an objective, goal-related developmental outcome years later. We followed up on initially childless couples in which both partners had reported the goal of starting a family within the next three and a half years. At baseline, partners reported on their general behavioral tendency to prioritize goals of particular importance in their partnership (i.e., their motivational selectivity). Three and a half years later, 50% of the couples had realized the goal to have a child. The higher the couples' initial motivational-selectivity scores had been, the more likely they were to have indeed started a family, controlling for other potential predictors of child-bearing. These findings suggest that motivational selectivity meaningfully characterizes social entities like couples, and regulates their development.
