- The page Getting Started shows how the toolbox works and the Demos page shows simple examples.
- The pages Presenting Choices and Online Trial Generation explain the two core functionalities of this toolbox. Choice Calibration is a notable application of online trial generation.
- Additional functionalities of the toolbox can be found on the Touchscreens, plugins, and timing and Useful functions pages.
OTG stands for Online Trial Generation, which is the algorithm at the heart of this toolbox. Its purpose is to produce economic choice trials in decision-making experiments where the participant makes cost-benefit trade-offs. Importantly, economic choices are not created before the experiment starts, but while the decision-maker performs the experiment. The main objective of this toolbox is to apply an algorithm that generates such trials and updates an estimate of the decision-maker's indifference curve with every choice that is made. A secondary purpose is to present these generated trials in an idiosyncratic way (notably, with a symbolic visual representation of the costs).
The toolbox consists of scripts that have the prefix BEC_ (for "Battery of Economic Choices"). Some of the functions are at the heart of the toolbox' functionality, notably:
- functions related to online trial generation,
- functions related to choice presentation and visualization.
In addition, the toolbox contains several convenience functions that we have applied in past experiments and that are likely to be useful to future studies, too. Finally, there are demo scripts that showcase the toolbox and that can be easily adapted for future experimental purposes.
The OTG toolbox is currently fully MATLAB-based and makes use of two other toolboxes: the Psychtoolbox for anything related to presentation on screen, and the VBA toolbox for online trial generation (although there is a version that does not require VBA). It is assumed that you have both toolboxes installed and added to your MATLAB path.
The ambition has been to make the OTG toolbox, in its entirety or only just its components, easy and intuitive to use. This should encourage users to apply it to their experiments and produce results that are comparable and reproducible between studies.
The toolbox was first developed in 2020, and since then it has been used and improved throughout multiple studies by myself and collaborators. As of 2021, this wiki is online. Should the information on this wiki not suffice, you can e-mail me (roelandheerema@hotmail.com).
