A simple and cheap setup for timing tapping responses synchronized to auditory stimuli.

Area of Science:

• Cognitive psychology
• Neuroscience
• Human-computer interaction

Background:

• Accurate measurement of human timing capabilities is crucial for understanding cognitive processes.
• Existing experimental setups for precise response time recording are often expensive or complex.

Purpose of the Study:

• To present a detailed, low-cost experimental setup for auditory stimulus presentation and response time recording.
• To achieve millisecond precision in timing experiments using accessible hardware.

Main Methods:

• Utilized a conventional PC with an external sound card for auditory stimulus delivery.
• Developed a system for recording tapping response times with high precision (within 2 ms).
• Provided detailed instructions for setup, use, and analysis code.

Main Results:

• The setup is significantly cheaper and requires fewer programming skills than alternatives.
• Achieved recording precision within 2 ms lag.
• Analysis code validation showed no spurious or missing events in 94% of recordings.

Conclusions:

• This accessible setup enables precise measurement of human timing capabilities.
• It overcomes the limitations of conventional computer setups for timing research.
• Facilitates research in areas requiring accurate response time data.
