The effects of the framing of time on delay discounting.

★ The Verdict

Calling a delay a calendar date instead of "days" makes people discount it less.

✓ Read this if BCBAs who write delay-based contingencies in clinics or classrooms.
✗ Skip if Practitioners working only with immediate reinforcement and no future choices.

01Research in Context

01

What this study did

DeHart et al. (2015) asked college students to pick between a small reward today or a bigger reward later. The twist was how the wait time was shown.

Some saw the delay as a calendar date ("May 15"). Others saw days ("45 days") or just units ("45 units"). Everything else stayed the same.

02

What they found

Calendar dates made people more patient. They discounted the future reward less. Days and generic units made them more impatient.

The framing, not the actual wait, shifted choice. Words on the screen changed real decisions.

03

How this fits with other research

Taylor et al. (2017) extends this lab trick into daily life. Their students exercised on their own for seven weeks. Self-monitoring cut discounting for most of them. Brady shows a quick wording fix; J shows a longer habit fix. Both lower delay discounting.

Kendrick et al. (1981) and Saunders et al. (1988) echo the power of instructions. They changed fixed-interval performance just by telling adults different rules. Brady moves the same idea to intertemporal choice: re-label time and behavior shifts.

Rogers-Warren et al. (1976) adds a clock and responses drop. External time cues help in both studies. A clock or a calendar date acts like a visual anchor that steadies behavior.

04

Why it matters

When you write token boards, visual schedules, or contingency maps, swap "14 days" for "March 3." The date frame can make waiting feel shorter and the reinforcer feel bigger. One small wording tweak may boost your client’s patience without adding extra tokens or tangibles.

03Original abstract

We examined the effects of the framing of time on delay discounting. Delay discounting is the process by which delayed outcomes are devalued as a function of time. Time in a titrating delay discounting task is often framed in calendar units (e.g., as 1 week, 1 month, etc.). When time is framed as a specific date, delayed outcomes are discounted less compared to the calendar format. Other forms of framing time; however, have not been explored. All participants completed a titrating calendar unit delay-discounting task for money. Participants were also assigned to one of two delay discounting tasks: time as dates (e.g., June 1st, 2015) or time in units of days (e.g., 5000 days), using the same delay distribution as the calendar delay-discounting task. Time framed as dates resulted in less discounting compared to the calendar method, whereas time framed as days resulted in greater discounting compared to the calendar method. The hyperboloid model fit best compared to the hyperbola and exponential models. How time is framed may alter how participants attend to the delays as well as how the delayed outcome is valued. Altering how time is framed may serve to improve adherence to goals with delayed outcomes.
