PST Serial Response Box
The Serial Response Box features a 0 millisecond debounce period. This is something that simply cannot be achieved from a standard keyboard! PST has engineered the Serial Response Box so that the response is time stamped and then the signal is verified for accuracy.
A standard keyboard verifies the accuracy of the signal before the response is time stamped. The problem of variable debounce periods found on keyboards is solved with the Serial Response Box!
Best of all, the PST Serial Response Box connects directly to the PC via the serial port! No additional hardware is required.
Refresh Detector System
The PST Serial Response Box includes a Refresh Detector System which is used to determine how many times a second the computer screen is redrawn or refreshed.
The PST Serial Response Box features 5 keys. Single key presses, key presses and releases as well as n-key rollover responses (e.g., collect information about key responses which overlap in time) are supported. The number of keys can be increased to 8 for use with E-Prime via the integrated expansion port (see the Custom Expansion Kit). The keys can be labeled in accordance with your experiment. Place a label inside the keycaps of the PST Serial Response Box's 5 keys. PST ships 5 sheets of labels with every PST Serial Response Box ordered.
The PST Serial Response Box features 5 lamps. A sample of 5 colored lamp covers are also included with the PST Serial Response Box. The lamp covers are easily interchangeable.
The PST Serial Response Box also features an integrated voice key. The voice key allows you to collect vocal latencies with confidence. This is not to be confused with the ability to record actual vocal responses. To record vocal responses we suggest the use of an external recorder. The voice key features both a hardware volume control and sensitivity control via E-Prime.
