Trial Configuration

Design Type

Single Configuration Blocked Design

Total Trials

Maximum Pumps

Reward Per Pump

Balloon Color

Popping Point System

Average to Mean Manual Entry

Popping points randomly generated per participant, averaging to half of maximum pumps.

Prevent early balloons from popping

The first 2 balloons will only pop at the maximum number of pumps, so participants can explore freely without an early pop anchoring their behavior. These balloons are not included in the average-to-mean calculation.

Enter popping points separated by commas. Each value should be between 1 and 64. You need 30 values (one per trial).

Popping Points

0 points entered

Block Configuration

Define different settings for each block of trials.

Total: 0 trials across 0 blocks

Input Mode

Click/Tap Mode Keyboard Entry

Click mode: Participants click "Pump" repeatedly. Keyboard mode: Type desired pumps and submit.

Balloon Inflation Style
