steingroever_2015_data
This data-pooling paper benchmarks healthy adult Iowa Gambling Task (IGT) performance across 10 independent studies, providing a "super control group" of N=617 participants. The data are trial-level: on each of 95–150 trials participants choose one of four decks (A–D) and receive win/loss feedback; the choice and resulting win and loss amounts are recorded per trial, along with a subject-to-study index. The three experiment files correspond to the three trial-count groups: exp0 (95 trials, N=15, all from Fridberg), exp1 (100 trials, N=504, from Horstmann/Kjome/Maia/Premkumar/SteingroverInPrep/Wood/Worthy), and exp2 (150 trials, N=98, from Steingroever2011/Wetzels). The dataset supports benchmarking healthy IGT performance and computational model-comparison of decision-making under uncertainty.

You are taking part in the Iowa gambling task. You are given a loan of $2000 in play money. In front of you are four decks of cards, labeled A, B, C, and D. On each trial you pick one card from one of the four decks by pressing the letter of that deck: A, B, C, or D. After each choice you win some money, and sometimes you also lose some money.
