<div dir="ltr">Hi, <div><br></div><div>I would like some tips to code a dual task. My experiment is a memory task with an encoding condition in divided attention. </div><div>More precisely, subjects have to listen to musical excerpts (mean duration around 10 sec) while they have to respond to a series of trials involving responding to digits.</div><div>I followed the dual task sample available on the PST website and did exactly the same (i.e. "<span style="color: rgb(0, 0, 0); font-family: 'Trebuchet MS', Arial, Helvetica; font-size: small;">The start time is determined at the beginning of the trial. The object presenting the word has a Duration value of zero msec. This displays the word, then immediately begins presentation of the digit task. The duration of the word is set as an attribute in the WordList, but the actual run-time duration is monitored by the digit trial"s)</span></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2"><br>However, although the task is running without error, I can hear any sound. This is probably due to the duration value of zero msec of the sound "object", but if I change this value, this is not a dual task anymore since the sound is first heard THEN digits appeared.</font></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2"><br></font></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2">Looking forward to read some help.</font></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2"><br></font></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2">Thanks, </font></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2"><br></font></div><div><font color="#000000" face="Trebuchet MS, Arial, Helvetica" size="2">Pauline </font></div></div>
