Hi,

I wanted to ask about a problem I've been having wherein when I run my expt. my first block just loops and never seems to end. I only have 34 trials (wrote in 'sequence') but so far have recorded those same trials being repeated until Inquisit seemingly crashed at 148 consecutive trials. I've attached the end of my script below (Blocks and Expt.):

<block practice_1>
/ preinstructions = (practice_1)
/ trials = [1-4 = random (HRT1,HRT4,LRT2,LRT7)]
</block>

*****************
<block 1>
/ preinstructions = (instructions_1; instructions_2)
/ trials = [1-34 = sequence (HRT2, LRT14, LRT15, HRT4, HRT11, LRT3, LRT16, HRT16, LRT5, HRT9, HRT15, LRT8, HRT1, LRT1, HRT8, LRT17, HRT5, HRT17, HRT12, LRT10, LRT12, HRT14, LRT4, HRT18, LRT9, LRT18, LRT7, HRT13, HRT3, HRT7, LRT2, LRT13, LRT6, HRT10)]
</block>

<block 2>
/ preinstructions = (block2_break)
/ trials = [1-34 = sequence (HRT12, LRT8, LRT3, HRT10, HRT13, LRT5, HRT11, HRT14, LRT17, LRT12, LRT1, LRT4, HRT15, LRT7, LRT9, HRT9, HRT17, LRT10, LRT18, LRT15, LRT11, HRT6, HRT1, LRT13, HRT3, HRT4, HRT16, HRT5, LRT14, LRT16, HRT8, LRT2, HRT2, HRT18)]
</block>

*************************************************************** EXPERIMENTS ***********************************************************************

<expt 1>
/ blocks = [1= practice_1; 2=1; 3=2]
</expt>

The 'practice_1' block works fine, but then block '1' continually repeats and block '2' never begins (I've checked the output and all of the trials are from '1'). I've also attached the script in case I've not given enough info here.

Any advice is massively appreciated!

Cheers,

Jay

/ trials = [1-34 = sequence (HRT2, LRT14, LRT15, HRT4, HRT11, LRT3, LRT16, HRT16, LRT5, HRT9, HRT15, LRT8, HRT1, LRT1, HRT8, LRT17, HRT5, HRT17, HRT12, LRT10, LRT12, HRT14, LRT4, HRT18, LRT9, LRT18, LRT7, HRT13, HRT3, HRT7, LRT2, LRT13, LRT6, HRT10)]

Means "run the entire specified sequence 34 times", i.e., your block will run 34 x 34 = 1156 trials. The proper syntax is

/ trials = [1 = sequence (HRT2, LRT14, LRT15, HRT4, HRT11, LRT3, LRT16, HRT16, LRT5, HRT9, HRT15, LRT8, HRT1, LRT1, HRT8, LRT17, HRT5, HRT17, HRT12, LRT10, LRT12, HRT14, LRT4, HRT18, LRT9, LRT18, LRT7, HRT13, HRT3, HRT7, LRT2, LRT13, LRT6, HRT10)]

Glad to help. And yes, it's not entirely obvious that this is the intended behavior of sequence() when used in the a <block>'s /trials attribute or an <expt>'s /blocks attribute.
