Executive Function (Impulse Control)
Delay Discounting Task
Choose between smaller immediate rewards and larger delayed rewards across 5 adjusting trials per block to estimate your delay discounting rate.
- Choose between two rewards on each trial: a smaller amount available now, or a larger amount available after a delay.
- Your choices adjust the immediate amount across 5 trials. There are no wrong answers — pick what you genuinely prefer.
- After each block, the next block uses a different delay period. Complete all blocks to see your discounting profile.
- Respond honestly. The test estimates how much you discount future rewards relative to immediate ones.
What does the Delay Discounting Task measure?
It measures temporal discounting — how steeply you devalue future rewards relative to immediate ones. Across 5 adjusting trials per delay period, you choose between a smaller amount available now and a larger amount available later. Your indifference point at each delay estimates your discounting rate (k), which reflects impulse control and temporal decision-making.
How should you interpret your delay discounting result?
A lower discounting rate k usually means you value future rewards more. In this short version the 1-day choices weigh most: even choosing Later on every trial gives a k of about 0.023, so read your indifference point at each delay rather than relying on the band name. A higher rate (k > 0.08) indicates steep discounting where delayed rewards feel substantially less compelling, which can make it harder to prioritize studying for distant exams over immediate gratification.
How does delay discounting connect to learning?
Studying is the ultimate delayed-reward activity: you invest effort now for a payoff (grades, understanding, career opportunities) that arrives weeks, months, or years later. Students with steeper discounting struggle to initiate spaced study sessions because the exam feels too distant. Recognizing your discounting profile helps you build external structure — deadlines, accountability systems, and shorter feedback loops — to compensate.
Why does Vidbyte include a Delay Discounting Task?
How you weigh present effort against future reward matters for learning: in one well-known study, eighth graders' self-discipline, measured partly with delay-of-gratification choices, predicted their grades better than IQ did (Duckworth and Seligman, 2005). Vidbyte includes this task because understanding how you weigh present effort against future reward helps explain why some study strategies fail and others succeed — and points toward the structural support (spaced scheduling, micro-rewards, accountability) that bridges the gap.

Research Basis
Koffarnus & Bickel (2014) — brief adjusting tasks
Koffarnus and Bickel's 5-trial adjusting delay task estimates a discount rate in under a minute by changing the delay; this game instead adjusts the immediate amount over 5 choices at each fixed delay.
Delay discounting and executive function
Shamosh and colleagues found that steeper delay discounting goes with lower working-memory and intelligence scores, linking temporal valuation to cognitive control.
Millisecond Inquisit Delay Discounting Library
The task appears in the Millisecond/Inquisit research-oriented digital assessment library as a validated delay discounting paradigm.
Temporal discounting and self-control
Reimers and colleagues found that a single delay discounting choice was associated with age, income, education, and real-world impulsive behavior.
