Thanks Dave.
Can you pl guide me to a script which can do the following.
I have 10 sounds.
Sounds to be randomly presented.
In Slidertrial 1 participants select whether the sound is happy or sad.
In Slidertrial 2 participants rate the same sound (which was presented in slidertial 1) as how happy or sad.
Similarly, all 10 sounds are randomly presented and rated.

<sound mysound>
/ items = sounditems
/ select = values.sounditem
</sound>

<item sounditems>
/ 1 = "sound01.wav"
...
/ 10 = "sound10.wav"
</item>

<values>
/ sounditem = 1
</values>

<list sounditemnumbers>
/ poolsize = 10
</list>

<slidertrial slidertrial1>
/ ontrialbegin = [
    values.sounditem = list.sounditemnumbers.nextindex
]
/ stimulustimes = [0=mysound, ...]
...
</slidertrial>

<slidertrial slidertrial2>
/ stimulustimes = [0=mysound, ...]
...
</slidertrial>

<block myblock>
/ trials = [1-10 = sequence(slidertrial1, slidertrial2)]
</block>

Thanks, Dave. One last question- I want participants to use only computer for the study (and not other devices). Can I block the study on mobile phone, tablet etc.

Yes, you can use script.abort() /onexptbegin if the computer.platform property doesn't match the platforms you want to allow. Or you can check whether the device has a physical keyboard available, which should be even easier.

<expt>
/ onexptbegin = [
    if (!computer.haskeyboard) {
        script.abort();
    }
]
...
</expt>
