Using a short-term longitudinal design, the authors investigated implications of 2 facets of motivational selectivity--restricting (to few goals) and focusing (on central and similar goals)--for goal-pursuit investment. Participants were 20-69 years old (Time 1, N = 177; Time 2, N = 160). Results show that motivational selectivity in terms of focusing (but not in terms of restricting) is associated with an enhanced involvement in goal pursuit (assessed 3 months later), irrespective of age. Structural equation models demonstrated that this association is completely mediated by the degree of mutual facilitation among goals. Furthermore, motivational selectivity increases from middle to older adulthood. This contributes to the maintenance of high goal involvement into later adulthood, despite aging-related increases in resource limitations.
作者采用短期纵向设计，研究了动机选择性的两个方面——限制（目标数量少）和聚焦（关注核心且相似的目标）——对目标追求投入的影响。参与者年龄在20至69岁之间（第一次测量，N = 177；第二次测量，N = 160）。结果表明，无论年龄大小，聚焦方面（而非限制方面）的动机选择性与目标追求投入的增强有关（在3个月后进行评估）。结构方程模型表明，这种关联完全由目标之间的相互促进程度所介导。此外，动机选择性从中年到老年期会增加。这有助于在成年后期维持较高的目标投入，尽管与年龄相关的资源限制有所增加。
