IOWA Gambling Task (IGT) 4 Choices (2 Bad Deck-A&B, 2 Good Deck, C&D) For Gains/Losses conditions: GainLosConds.xlsx

Reversal learning with probabilistic high vs low reward fractal images. Fractal images are isoluminant. 3 periods in each block with 2 reversals - this is determined by code, so can be changed, as can the number of blocks.

In this task participants are required to judge whether there are more dots on the left or right side. This experiment is based on Damos and Gibb (1986) experiment.
