BackgroundIt doesn't matter which experiment generator you use to run your computer-based Psychology experiments the Black Box ToolKit USB response pad helps improve your millisecond reaction time (RT) accuracy.
Truly plug in and play as our USB response pad appears to your computer as a second keyboard and each button press produces a standard key press!
Millisecond accurate 1-8 button USB response pad key features
Simply plug in to a USB port on your PC/Mac/Linux system and our response box will appear as a second keyboard. Press a button and a standard keystroke will be sent to your experiment.
No need for drivers, no need to recode! Works out of the box with E-Prime, SuperLab, Presentation, Inquisit, PsychoPy or any other software that can accept standard keyboard responses.
Finished in an attractive carbon fiber effect our response box houses up to 8 buttons in a range of colors and locations. Sister model with integrated voice key now shipping.
To measure a real world RT of 300ms accurately you need all components of your system to be functioning optimally. We guarantee that the variability of our response devices is as low as possible compared with any other alternative. For example a typical keyboard and mouse have a much greater level of inaccuracy and variability (in this example 340ms and +/- 27ms).
*Remember although our USB response pads are millisecond accurate and help reduce RT variability in your experiments they can't automatically correct for any mistimings that are inherent within the experiment generator you use. Hardware capable of sub-millisecond accuracy. Timing accuracy tied to PC and experiment generator used.
If you wish to check the accuracy and consistency of your experiment generator, or system as a whole, you are advised to use a Black Box ToolKit v2 together with a BBTK USB response pad. For event marking you should combine a response pad with our mBBTK v2 which is designed for monitoring stimuli and TTL event marking/sending TTL triggers. The mBBTK v2 can also take over the timing duties from your experiment generator completely so you can be 100% sure of your presentation, synchronization and response timings.
Range of button colors, sizes and clear caps
A range of colored buttons are available to order.Clear cap buttons allow you to put your own labels under a tamper-proof clear plastic cover. Simply unscrew the button, remove the clear cap and place your own label under the button top (21mm dia).
Clear cap buttons are available in a range of colors. The key cap is always clear to enable your participants to see your label underneath.
Smaller diameter buttons are also available on request.
Custom laser cut layouts to your own designYou can customize your button layout by electing where to place between 1 to 8 buttons. Lid measurement 202mm length x 137mm width.
To help we have provided downloadable templates you can use with your favorite drawing package to customize your layout.

|Connector||What does it do||How can I use it|
|8x TTL||A dedicated TTL line for each button that operates with sub-millisecond accuracy for TTL event marking/TTL triggers. Active high for the duration of each button press.||Ideal for +5V TTL event marking/TTL triggering of true individual button response times or for time audit, e.g. in EEG, connection to a BBTK etc. 8 bit port.|
1 to 4
(3.5mm mono sockets)
|Up to 4x external buttons of your own can be used.||When you connect your own push-to-make buttons via the 3.5mm sockets these work alongside the corresponding response pad buttons. Participants can press either your external button or our response pad button to make a response.|
(USB 'B' square socket to PC 'A' flat)
|Connects to the PC you want to accept responses on.||Each button sends a standard key down response as might a normal keyboard if you pressed keys 1-8 for example.|
(2.5 mm stereo socket)
|When any button is pressed a 50ms wide TTL pulse is sent to this socket. This can either be a positive or negative pulse depending on which signal line you use.||For simple event marking of true response times or for time audit, e.g. in EEG, connection to a BBTK etc.|
(female 9-way D connector)
|4x TTL lines connect to the BBTK via this connector. If you are using a BBTK v2 when you press a button a +5V TTL event (onset, duration and offset) is captured by the BBTK for time audit purposes.||When connected to the BBTK v2 if a button is pressed a keystroke is sent to the computer you are running your experiment on. Simultaneously a TTL event marker is sent to the BBTK which logs the button press in terms of onset, duration and offset. It is also possible to use these +5V signals to event mark on EEG and for time audit purposes.|
