Hey there,

I want to program an AAT (approach avoidance task) were you have to pull non_alcoholic drinks towards you and push alcoholic drinks away from you.
Its connected with a sequence generator.
I have two groups. alcoholic and non-alcoholic pictures.
I want each item two be used 3 times that makes a total of 150. selection should be random.
below you see the sequence genarator script.
Thank you all

<values>
/count1 = 25
/count2 = 25
/totaltrialcount = 150

/runcount_1 = 0
/runcount_2 = 0

/newnumber = 0
/count_comparecat = 0

/sequence = ""
/index = 0
/reset = 1
</values>

Trial Selectnumber: selects the newnumber and checks whether
all constraints are met
- if all constraints are met: adds new number to sequence
- constraints are not met: checks whether an alternative number is available that could meet constraint
                            => if yes: returns current number to list and tries again
                            => if no: starts the sequence over
