Hi,

I would like some instruction sentences to constantly appear at the bottom edges of the screen during the whole duration of the task.
I have been using the bg attribute as follows up to now:

<block testblock>
/ preinstructions = (test)
/ trials = [1-80=noreplace(congruenttrial,incongruenttrial)]
/ bgstim = (leftinstruct, rightinstruct)
</block>

<text leftinstruct>
/ items = ("Z = UP")
/ hposition = 15
/ vposition = 95
/ fontstyle = ("Verdana", 2.00%, true)
</text>

<text rightinstruct>
/ items= ("M = DOWN")
/ hposition = 85
/ vposition = 95
/ fontstyle = ("Verdana", 2.00%, true)
</text>

<trial congruenttrial>
/ ontrialbegin = [if(script.currentblock=="practiceblock")
{
values.stimtype=counter.pcongruentstimtype.selectedvalue;
values.cresp=counter.pcongruentcresp.selectedvalue;
}
else
{
values.stimtype=counter.congruentstimtype.selectedvalue;
values.cresp=counter.congruentcresp.selectedvalue;
}]
/ posttrialpause = 500
/ stimulustimes = [0=fixation, leftinstruct,rightinstruct;500=blank, leftinstruct,rightinstruct; 1050=stimulus, leftinstruct, rightinstruct]
/ trialduration = 2600
/ responsetime = 1050
/ validresponse = (44,50)
/ iscorrectresponse = [trial.congruenttrial.response==values.cresp]
</trial>

<trial incongruenttrial>
/ ontrialbegin = [if(script.currentblock=="practiceblock")
{
values.stimtype=counter.pincongruentstimtype.selectedvalue;
values.cresp=counter.pincongruentcresp.selectedvalue;
}
else
{
values.stimtype=counter.incongruentstimtype.selectedvalue;
values.cresp=counter.incongruentcresp.selectedvalue;
}]
/ posttrialpause = 500
/ stimulustimes = [0=fixation, leftinstruct,rightinstruct; 500=blank, leftinstruct,rightinstruct; 1050=stimulus, leftinstruct, rightinstruct]
/ trialduration = 2600
/ responsetime = 1050
/ validresponse = (44,50)
/ iscorrectresponse = [trial.incongruenttrial.response==values.cresp]
</trial>

The problem is that between each trial these instructions disappear and I would like them to remain on the screen all the time (I don't want them just flashing during the trials).
When I put a bgattribute in the block element, the background stimuli only appear at the beginning of the block. That is why also put:
       / stimulustimes = [0=fixation, leftinstruct,rightinstruct; 500=blank, leftinstruct,rightinstruct; 1050=stimulus, leftinstruct, rightinstruct]

Thank you for your help!
