Decision Making

Balloon Risk Task

Measure risk taking with pump-or-collect choices on balloons that pop at random points, scored by adjusted average pumps.

Useful for risk-taking, reward sensitivity, impulsive-choice, and intervention research.

What this task measures

Measures risk taking as participants pump balloons for points and decide when to collect before a pop.

Core constructs

  • Risk taking
  • Reward sensitivity
  • Impulsivity
  • Decision making under uncertainty

Research fit

  • Risk-taking research
  • Substance-use and addiction studies
  • Impulsivity batteries
  • Within-study group comparison

Paradigm overview

Balloon Risk measures risk taking. Each press of Pump adds 5 points to the current balloon. Participants can collect the points at any time, but if the balloon pops first, its points are lost. The task shows the outcome after every balloon.

As in the Balloon Analogue Risk Task of Lejuez and colleagues (2002), each balloon pops at a point drawn at random from 1 to 128 pumps. The chance of a pop is 1 in 128 on the first pump and rises with each pump until a pop is certain at pump 128. The average pop point is about 64 pumps. Pop points come from a seeded generator and are saved with the trial data. The standard task has 30 balloons.

The main score is the adjusted average pumps: the mean number of pumps on balloons that did not pop. Scores also include the explosion rate, total points, adjusted pumps for each block of 10 balloons, and the change in pumps across the task.

Key scoring outputs

Adjusted Average Pumps

pumps

Mean pumps on balloons that did not pop.

Higher means more risk taking

Explosion Rate

proportion

Share of balloons that popped.

Informational

Total Points

points

Points collected across all balloons.

Informational

Risk Escalation

pumps per balloon

Change in pumps from one balloon to the next, from a straight-line fit over balloons that did not pop.

Positive values mean rising risk taking

Adjusted Pumps by Block

pumps

Adjusted average pumps within each block of 10 balloons, reported as adjustedPumpsBlock1, adjustedPumpsBlock2 and so on.

Task design as built

The trial sequence participants see, as the test runs in ConductCognition. Settings a researcher can change are listed below.

Pump
Each pump adds 5 points to the current balloon. Collect banks them; a pop loses them.
Pop point
Drawn at random from 1 to 128 pumps for each balloon and saved with the data.
Feedback
The outcome of each balloon shows for 1.5 seconds.

The original task also used balloons with lower pop limits and paid money for each pump. This version uses one balloon type, with pop points from 1 to 128 pumps, and points.

Research FAQ

Common questions about this online cognitive test

How long does the Balloon Risk Task take?

About 5 to 9 minutes, as listed in the test library.

What device does a participant need?

Untimed test: runs on desktops, laptops, tablets and phones. The browser must be Chrome, Edge, Firefox or Safari.

What scores does it produce?

Adjusted Average Pumps, Explosion Rate, Total Points, Risk Escalation and Adjusted Pumps by Block. Each session is also marked valid, needs review or invalid, with the reason.

Which settings can a researcher change?

Number of balloons (15 to 60). Settings can be changed on yearly plans; free and pay-as-you-go studies use the standard settings.

Which languages can participants use?

The test's own text is in English and Italian. Italian participant pages come with yearly plans.

Is this a clinical test?

No. ConductCognition is for research use only. It runs, scores and exports the test; clinical interpretation is outside the platform.
