Hi guys,

I have been trying to work on the Matlab script I have wrote to measure the RT for the task.

However, the Matlab program returns back to the screen with the following message after the first stimulus has presented (I have two stimuli to be presented, the first stimulus always appears before the onset of the second stimulus. Whar's more is response key for the first stimulus needs to be pressed before the onset of the second stimulus).

No appropriate method, property, or field 'MergedKeys' for class 'PollClass'.

More scripts are shown below:

myKbd = PollClass(0.005);
myKbd.Reset;  % Time0 is set here.
Times = myKbd.Times - myKbd.Time0;
NResps = myKbd.NKeys;
if NResps==1
    RT1 = myKbd.Times(1);
    Resp1 = myKbd.MergedKeys;  
else
    RT1 = ExpInfo.NogoRT;
    Resp1 = {ExpInfo.HomeKey};
end
