IGT-Open: An open-source, computerized version of the Iowa Gambling Task.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Computational Modeling

Background:

• The Iowa Gambling Task (IGT) is a standard method for studying decision-making processes.
• Computerized versions enhance standardization and applicability in diverse research settings, including neuroimaging.
• Discrepancies across existing software implementations may affect experimental reliability.

Purpose of the Study:

• To introduce IGT-Open, a novel, open-source software implementation of the IGT.
• To provide a reliable and accurate tool for decision-making research and computational modeling.
• To facilitate standardized data collection across studies and research environments.

Main Methods:

• Development of an open-source software package, IGT-Open.
• Implementation of millisecond-level visual presentation accuracy.
• Validation through data collection with human subjects and computational simulations within the ACT-R architecture.

Main Results:

• IGT-Open provides precise control over stimulus presentation timing.
• The software has been successfully employed in empirical data collection.
• It is compatible with computational process models, specifically those in the ACT-R architecture.

Conclusions:

• IGT-Open offers a reliable, accessible, and accurate platform for IGT research.
• This open-source tool promotes standardization and reproducibility in decision-making studies.
• It supports both empirical investigation and computational modeling of decision-making behavior.
