The keyboard is frequently used as a response collection device. However, when responses are collected through the keyboard, mouse, or touchscreen, there is a delay built into the response due to the nature of the hardware switches that are processing the response. It is important to note that the magnitude of the delay, typically around 12 ms for a keyboard, may be so small when viewed in the context of the typical standard deviation for average reaction times, typically over 100 ms, as to be acceptable.
If the delays that are built into the responses that are sent by the keyboard, mouse, or touchscreens meet your experiment requirements, then any of these devices can be used with E-Prime 3.0. However, if your paradigm requires more precise timestamps of participant responses than what is available from a keyboard, mouse, touchscreen or joystick, refer to the following articles for alternatives to the keyboard and mouse for collecting a response:
