lab.js

lab.js enables creation and deployment of web-based and laboratory behavioral and cognitive experiments for precise presentation and response timing and structured data collection.

Key Features:

• Customization with Code: Supports advanced customization of experiments using HTML, CSS, and JavaScript.
• High-precision Timing: Measures presentation and response times with high temporal precision in browser-based and local contexts.
• Deployment Options: Exports experiments for execution on local computers, any web server, or cloud hosting services and integrates with data collection platforms.
• Reproducible Study Sharing: Enables archiving and sharing of experiments in editable formats to facilitate reuse, replication, and collaboration.

Scientific Applications:

• Experimental psychology: Implementation and timing-sensitive execution of behavioral paradigms for cognitive and perceptual studies.
• Cognitive science: Presentation of stimuli and collection of response data for studies of attention, memory, language, and decision making.
• Online and laboratory data collection: Running identical experimental code in both web-based and laboratory settings for comparative or distributed data collection.

Methodology:

Experiments are constructed with HTML/CSS/JavaScript, exported to run locally or on web servers/cloud, instrumented to record presentation and response timing, and integrated with data collection platforms; studies can be saved and shared in editable formats.
