as follows(referring to the attached file, question 1)

ex) [ one-> blank -> three -> blank -> four -> blank ]
=> [3 -> blank -> 4 -> blank -> 2 -> blank]
=> [ II -> blank -> IV -> blank -> I -> blank -> III -> blank]

====================================================
Question 2.

how to present 2 elements out of 10 in stimulus list randomly without repeated presentation of each element and at the same time how to make sure that all the elements at each trial are presented.

as follows(referring to the attached file, question 2)

ex) [+ -> II -> blank ==> + -> IX -> blank ] ==> [+ -> 3 -> blank ==> + -> 6 -> blank ] ==> [+ -> I -> blank ==> + -> V -> blank ] ==> [+ -> 5 -> blank ==> + -> 10 -> blank ] …

For your first question I recommend creating more blocks, possibly as many block as you have trials. Then, randomize under the block level.

Regarding your second question, as I understand it you want to present at random from list “number” two items followed by two items at random from list “one” and so on? Is this correct? Is it all right if I demonstrate this in version 5 as it is easier?
