Type

string

Remarks

The responseTime property holds the absolute UTC time in ISO 8601 format on the device clock at which a response was made.

This property is useful for synchronizing with external data streams that use the device clock. To measure reaction times, use the latency property, which reports the relative response time in milliseconds.

Examples

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

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

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

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