EXPLAN--a programming language for complex visual stimuli presentation

Area of Science:

• Cognitive Science
• Computer Science

Background:

• Visual cognition research necessitates dynamic and structured spatial patterns as stimuli.
• Existing methods for stimulus generation can be inflexible, limiting experimental design.

Purpose of the Study:

• To develop a specialized programming language and compiler for creating adaptable visual stimuli.
• To facilitate complex stimulus presentation and reaction monitoring in visual perception studies.

Main Methods:

• A domain-specific programming language was designed for visual stimulus generation.
• A compiler was implemented to translate the language into executable programs.
• The system supports precise control over stimulus parameters, including spatial, temporal, and interactive elements.

Main Results:

• The developed language enables the flexible presentation of visual stimuli with detailed control over parameters.
• It allows for the generation of complex stimulus sequences, including subliminal stimuli.
• The system integrates stimulus presentation, subject reaction monitoring, and automatic reporting.

Conclusions:

• The specialized programming language provides a powerful and flexible tool for visual cognition research.
• This approach streamlines the creation and execution of experiments involving complex visual stimuli.
• The successful utilization in visual perception research validates its efficacy and utility.
