Experiment Author: Psychology Software Tools, Inc.
The Balloon Analogue Risk Task (BART) is a test of risk-taking behaviors in participants.
Abstract
In the experiment, participants are presented with a balloon. The participant is prompted to inflate the balloon using the Right Arrow key. After successfully inflating the balloon by 1 unit, the participant receives five points. The more the participant inflates the balloon, the more points they receive.
E-Prime randomly selects a number between 1 and 100 for each trial representing the total number of inflated units before the balloon bursts. If the participant inflates the balloon too much, it pops and no points are given. Participants also have the choice to press the Left Arrow to advance the trial while keeping their points. There is one practice trial and 5 critical trials.

I have some questions .
1. If i want to make 1.5s~2.5s between balloon pumps, what can i do?
2. what if i want maximum pumps 12 per each ballons, what can i do?
3. how to change probablity of explosion ? i want to make it gradually increment. like 0.0 % -> 2.1% -> 4.2%->6.3%->14.6
if you can help me, i will really appreciate you.
thanks for reading my comment.

Hello
I am Mostafa Deldoost . recently I got interested in behavioral economics and now I am researching on it.
I have a question about BART so I appreciate if you answer it.
how can I classify risk taker and risk seeker person based on 30 trial BART
test, I mean what is the critical factor that I can say if a person get less
than on is risk seeker or risk lover.
for example in one experiment adjusted number of pumps was 50 , this person
is risk lover or risk seeker? what is the role of reward ? should I compute
expected earning ? how?
Can I apply BART test in order to classify a person in terms of economic risk not social risk like drug ?
I appreciate if you forward me the computation in spread sheet or Matlab for
a real or artificial experiment.
Sorry for the inconvenience.
Regards,
Mostafa
