Have some stimuli delay before appearing within a trial

Hi there,


I have a brief question. 


I have a study in which I have trials in which I do not want all stimuli to load simultaneously. 


Specifically, I want a phrase to appear in the center of the screen. 1500 ms later, I want three stimuli to appear below that the user can click on. 


Here is what I have for an example of one of these trials. What want to do is figure out how to make "description" load when the trial loads, then have "cho_1" "cho_2" and "cho_3" appear 1.5 seconds later. Is there an easy way to tell the trial to pause before loading some stimuli?




<trial cho>

/stimulusframes = [1=description, cho_01, cho_02, cho_03,]

/validresponse = (cho_01, cho_02, cho_03)

/correctresponse =  (cho_01)

/inputdevice = mouse

</trial>

Thanks

/stimulustimes = [0=description; 1500= cho_01, cho_02, cho_03]

/validresponse = (cho_01, cho_02, cho_03)

You will find elementary things like this covered in the tutorials.
