Remarks

By default 'latency' stores the time (in ms) from onset of the last scheduled trial event until the response is made. The trial onset time for the 'latency' measure can further be fine-tuned by setting attributes and/or properties 'beginResponseTime/beginResponseFrame'.

Examples

The following displays the value of latency in a text stimulus:

<text myText>
/ items= ("latency = <% trial.myTrial.latency %>")
</text>

The following displays the value of latency in an instruction page:

<page myPage>
latency = <% trial.myTrial.latency %>
</page>
