What was done
Across five studies and an internal meta-analysis, the authors evaluated whether immediate rewards (such as experiential enjoyment) or delayed rewards (such as future health improvements) better predict persistence in goal-directed activities. The contexts examined included adherence to New Year's resolutions (Study 1), single sessions of studying and exercising (Studies 2 and 3), persistence over 1-week and 3-month intervals (Study 4), and anticipated versus materialized rewards (Study 5).
What was found
The abstract reports no numerical values, sample sizes, or effect estimates. It reports that immediate rewards consistently predicted actual persistence across all tested contexts (New Year's resolutions, study sessions, exercise, 1-week and 3-month durations, and anticipated/materialized rewards), whereas delayed rewards did not, despite participants reporting delayed rewards as their primary motive for pursuing the goals. An internal meta-analysis across the studies supported that immediate rewards are more strongly associated with actual persistence than delayed rewards.
Why it matters
The paper highlights a fundamental disconnect in motivation: while delayed rewards drive goal setting and intention, immediate positive experiences during goal pursuit dictate actual adherence.
Limits
No sample sizes, participant demographics, effect estimates, or confidence intervals are reported in the abstract. The studies appear observational rather than randomized trials manipulating reward timing, and internal meta-analyses of an author's own studies are susceptible to selective reporting bias.
