Remarks

The systembeep element is built-in, there is no need to explicitly declare it in the script. It is a type of stimulus, so it can be used wherever a stimulus element is valid. The systembeep is useful for providing audio feedback (e.g., to indicate an incorrect response). The advantage of using systembeep rather than the sound element is that it does not require a sound card. By default, the duration of the beep is 250 ms and the frequency is 750 hz.

Examples

The following trial presents a beep.

<trial beeptrial>
/ stimulustimes = [1=systembeep]
/ validresponse = (anyresponse)
</trial>
