This batch script implements the Angling Risk Task (ART) as described in:
Pleskac, T.J (2008). Decision Making and Learning While Taking Sequential Risks.
Journal of Experimental Psychology: Learning, Memory, and Cognition, 34, 167–185.
Note: the original ART as well as more detailed information can be obtained from Dr.Pleskac by request
Millisecond Software thanks Dr. Pleskac for sharing his original program as well as generously supporting our
efforts to replicate it in Inquisit!
Participants are playing in a fishing tournament for 30 (default) number of rounds.
The goal is to win as much money as possible during each round. Participants win money by fishing red fish out of a pond
that contains 127 red fish (default) and 1 blue fish. Each time they catch a red fish, they win 5cents (default)
which is put in a temporary bank. If they catch the blue fish instead, the current round is over and all money in the
temporary bank is lost. If participants don't want to lose their temporary money they have to decide when to stop
catching fish and collect the money they have earned. Once they decide to collect the money, the money is transferred
to a permanent bank and the current round is over.
Participants can play the game under
* 2 different weather conditions: a) 'clear' (all fish are visible) or b) 'cloudy' (no fish are visible)
* 2 different release conditions: a) 'catch n'keep' (fish are not returned to the lake => chance to fish blue fish increases with each successful fishing attempt)
b) 'catch n'release' (fish are returned to the lake => chance to fish blue fish stays constant)
This batch script runs
1. a practice session
2. all four conditions of the experiment: 8 different groupnumbers (orders)
