Two conditions

[Amy Eschman]

Leisha,

The Permutation method is more than you need to accomplish this
sampling.  If you want odd-numbered subjects to get one condition (out
of two) and even-numbered subjects to get the other, you should use
Counterbalance by Subject.

Permutation takes all possible combinations of the conditions, then
selects one of the possible combinations based on the Order By value and
runs all conditions within that combination in sequential order.

Hope this helps,

Subject: Two conditions


Hello E-Prime gurus,

I want to run two conditions, one with evaluable and one with 
nonevaluable stimuli. If I have a block list with two items that each 
call a different list of stimuli, then set the selection to permutation 
based on subject number, will odd-numbered subjects get ID number 1 and 
even-numbered subjects get ID number 2 consistently?

Your help is much appreciated.
