PsyBuilder: An Open-Source, Cross-Platform Graphical Experiment Builder for Psychtoolbox With Built-In Performance Optimization

Psychtoolbox is among the most popular open-source software packages for stimulus presentation and response collection. It provides flexibility power in choice of stimuli responses, addition to precision control timing. However, requires coding MATLAB (or its equivalent, e.g., Octave). Scripting challenging learn can lead timing inaccuracies unwittingly. also be time-consuming error prone even experienced users. We have developed first general-purpose graphical experiment builder Psychtoolbox, called PsyBuilder, both new The allows users graphically implement sophisticated experimental tasks through intuitive drag drop without need script. output codes built-in optimized come with detailed comments facilitate customization. Because see exactly how code changes modifications interface, PsyBuilder bolster understanding programming ways that were not previously possible. In this tutorial, we describe then walk reader building process using a concrete experiment, finally address important issues from perspective potential adopters.
