Chronos® - A Multifunctional Response and Stimulus Device


Chronos is a powerful new USB-based response and stimulus device. Chronos allows the accurate collection and verification of tactile, auditory, visual, and analog responses along with the precise source of audio and generic analog output timing. Chronos features millisecond accuracy and consistent sound output latencies across machines. Chronos includes 16 digital inputs and 16 digital outputs, eliminating the need for a parallel port. The Photo Sensor accessory (included) can be used on CRT, LCD, and projection displays to detect stimulus onset events, refreshes, and measure rise and fall times. All responses collected are synchronous to the E-Prime® time domain. Multiple Chronos devices can be connected to a single PC (E-Prime 2.0 Professional or E-Prime 3.0). The Chronos back panel features Kensington lock support to secure the device (lock not included).

 

The Chronos graphical user interface allows for user-friendly implementation of the system's wide range of features. Chronos also introduces a large set of Task Events to facilitate the design of basic to complex experiments without the use of script (E-Prime 2.0 Professional or E-Prime 3.0).
