Description
Typically the BBTK v3 operates as a virtual human programmed to respond to stimulus presentations and generate appropriate responses very accurately. It can step through your whole experiment as if it was a human participant. External sensors are hooked up to a second PC, Mac or Linux box to detect stimulus presentations and a generation interface is used to feed a response into the paradigm under test. The BBTK v3 measures the timing of all stimulus, synchronization and response events extremely accurately, allowing you to compare timing measured by your own equipment with the actual real world timings. The BBTK v3 can also work with up to 20 I/O TTL lines/TTL triggers when used in fMRI studies, for EEG or eye tracking. Show me a worked example.
Set-up – Hook up external stimulus sensors (opto-detectors, mics, TTL) and a response device (response pad, robotic key actuator, sounder, TTL)
Test – Use a wizard to select a stimulus pattern to automatically respond to/event mark. Then choose the exact reaction time, response device and duration
Analyze – Check your stimulus, response and synchronization timings across up to 36 channels. Compare what your experiment recorded with what the BBTK saw
The BBTK v3 also lets you tune your experiment generators accuracy in a particular study by automatically simulating a human participant that is millisecond accurate. This enables you to modify onsets, delays and RTs so that they are accurate in the real world. Remember the BBTK v3 is a dedicated self-contained hardware device that is designed to record stimulus onsets and reaction times in the real world as they occur with sub-millisecond accuracy. Simple to use with a range of external sensors. For a fit and forget solution for event marking be sure to check out our new mBBTK v3 (event marking version).
Wizard driven software makes benchmarking and calibrating your experiments timing quick and easy. For example, to check visual stimulus and RT accuracy simply attach an Opto-detector to your screen, select a real-world RT you would like the BBTK v3 to respond with and compare that with what your experiment presented and recorded. It’s as easy as 1, 2, 3!
