WELCOME TO THIS DECISION MAKING EXPERIMENT!
Click through these task instructions using the "Previous" and "Next" buttons at the bottom of the screen.
In this game you are a monkey looking for apples to eat in the forest.
Eating apples gives you health points and your aim is to gain as many health points as you can.
You will see three different trees: 1 red apple tree, 1 yellow apple tree and 1 green apple tree.
Your task is to choose one of these trees to take an apple from by clicking on it with your mouse.
Each of the trees has a chance that an apple you pick from it will contain a worm: none of the trees are ever completely free of worms.
If the apple you picked contains a worm, you cannot eat the apple so you will see a sad monkey face and win no health points.
If the apple you picked does not contain a worm, you can eat the apple so you will see a happy monkey face and win 10 health points.
As you continue to pick apples you may notice that the chance of the different coloured apples containing a worm will change as the worms afflict different types of trees during different seasons.
Regardless of season and distribution of worms among trees, there is always one tree with a majority of worm-free apples.
After a short practice phase you will make 210 choices.
You can see the total health points (black arrow) you have won so far, as well as how many choices you have left on each play (grey arrow). You can leave the game at any time by pressing the "Exit Study Now" button.
Again, your aim is to win as many health points as possible.
