Hi,
I would like to add a response screen in before my fixation point appears on my trial that allows participants to press space 'when ready to inhale'.

Essentially before each trial participants would need to inhale. I have created a separate trial called Inhale:
<trial Inhale>
/ stimulustimes = [1= inhale]
/ validresponse = (anyresponse)
/ correctresponse = (57)
/ recorddata = false
</trial>

Below is an example of the main experimental trials (its very long sorry :/ ) I would want to add the screen in before fixation on stimulus times. I just don't know an easy way to do this e.g. can you branch to the Inhale trial at the beginning of the Target_present trial? or is there a way to add this screen in as a stimulus in the trial (it would need to appear for unlimited time/ until participant presses space)

I don't know if I am making any sense so sorry if I am unclear but hopefully you can understand?

thank you in advance!

> I just don't know an easy way to do this e.g. can you branch to the Inhale trial at the beginning of the Target_present trial?

No. Since the inhale trial is supposed to precede the target_present trial, you need to do it the other way around. The program cannot go backwards in time.
From the inhale trial, /branch to the target_present trial.

Thanks Dave, Is there not an easier way to add a screen in though e.g. as a stimulus in my trial or for example in a block I have 48 trials so I write trials =1-48 list.set6trials, I want the inhale screen to appear before every trial would that mean I then have to write out out 1 =Inhale; 2=list.set6trials; 3 etc. This would take ages wouldn't it?

No, it does not mean that. You could simply do

<block set5block>
/ trials = [1-48 = inhale]
</block>

<block set6block>
/ trials = [1-48 = inhale]
</block>

with

<trial inhale>
...
/ branch = [if (script.currentblock == "set5block") {
    list.set5trials.nextvalue;
    } else if (script.currentblock == "set6block") {
    list.set6trials.nextvalue;
   };
]
</trial>
