Millisecond Forums

Hi,

I need some help to find out if Inquisit / Inquisit Web 5 can perform the following:

Problem: I have 5 stimuli and each stimulus has 3 conditions. 

Each participant will go through all 5 stimuli (trials) (order counter-balanced) with one of the conditions (randomly selected per stimulus).

I can achieve the within-subject randomisation and counter-balanced using noreplacenorepeat.

However, is it possible to do the following between subjects as well?

For example, if I need only 1 sample per stimulus per condition, then I need a total of 15 trials.

If I have 3 participants, can I configure Inquisit in a way such that all conditions and all stimuli are covered at most once?

I know I can potentially use <batch> and groupnumber to achieve something similar, albeit tedious, but just want to check if there is any built-in mechanism that will do this?

Any suggestion/comment would be much appreciated.

Regards,
Zhao
