Balloon Risk
The Balloon Analog Risk Task (BART) is a computerized risk-reward assessment. The participant taps to inflate a balloon โ each tap increases potential points, but if the balloon pops, all points for that balloon are lost. BART scores correlate with self-reported sensation seeking, impulsivity, and real-world risk behaviors including drug use, gambling, and sexually risky behavior.

Cognitive domain: Risk-taking behavior, decision-making
Configurationโ
| Setting | Description |
|---|---|
| Balloon Count | Number of balloons (trials) in the task |
| Breakpoint Mean | Mean number of taps before the balloon bursts |
| Breakpoint Standard Deviation | Variability in the burst threshold |

| Breakpoint Mean | breakpoint_mean | number |
| Breakpoint Std Dev | breakpoint_std | number |
Sample Instructionsโ
"Tap the button labeled 'Pump Up Balloon' to inflate it as large as you can, before the balloon bursts. When you feel like you can't inflate it anymore without it bursting, tap the button to 'Collect Points'. The number of times you pumped up the balloon will be equal to the number of points you get. If the balloon bursts, you get no points!"
Usageโ
The participant inflates a balloon by tapping. At any point, they can choose to "Collect Points" to bank the current inflation count. If the balloon pops before collecting, the participant receives zero points for that balloon. The burst threshold varies per balloon.
Scoringโ
If the balloon does not pop and the user collects, points equal the number of pumps. If the balloon pops, the user receives 0 points for that trial.
