Spontaneous Goal-Related Cognition Predicts Well-Being and Real-World Goal Attainment Across Adulthood in a Think-Aloud Study

Decades of research has established that how we think about our goals shapes psychological well-being and daily behavior, yet much of what we know derives from paradigms that deliberately prompt goal cognition. Across two studies (N = 173), we developed and applied a novel hierarchical coding scheme to Think-Aloud Protocol recordings to understand whether these same processes emerge spontaneously in the stream of consciousness, whether they carry meaningful consequences for real-world behavior, and how they change in older age. We quantified participants' spontaneous engagement in mental contrasting (MC), a self-regulatory strategy that links desired futures with present obstacles to facilitate solutions that promote effective goal pursuit, in the absence of instruction or prompting. In Study 1 (n = 77 young adults), higher depression and anxiety predicted less frequent spontaneous mental contrasting (MC3), while higher trait mindfulness predicted more frequent MC3 and less dwelling on obstacles. Study 2 (n = 95 younger and older adults) largely replicated and extended these findings, further revealing that despite a similar number of goal-related thoughts, older adults produced a higher proportion of MC3 thoughts relative to younger adults. Moreover, more frequent use of mental contrasting when spontaneously thinking about one’s goals predicted significantly greater goal progress and accomplishment over time, independent of age. These findings demonstrate that individuals spontaneously vary in the depth of goal-related elaboration during spontaneous thought, that these variations associate meaningfully with wellbeing and real-world goal success, and that spontaneous engagement in solution-focused goal elaboration seems to differ across the adult lifespan.
