The counter element defines a sequential or randomly selected set of values used to vary experimental conditions.
/ allowrepeats = boolean
/ select = integer or selectionmode or selectionmode(pool) or dependency(stimulusname) or dependency(countername) or countername
/ items = (value, value, value,... )
/ not = (stimulusname, stimulusname, stimulusname) or (countername, countername, countername)
/ resetinterval = integer
/ selectionrate = rate
The counter element can be used to determine which stimulus items are selected from trial to trial, providing more control over item selection than is given by the stimulus element itself. Counters can also be used to specify the values from trial to trial of variable attributes (for example, the horizontal and vertical screen position of stimuli).
The following counter returns a sequence of numbers counting backwards from 5.
/ select = sequence(5, 4, 3, 2, 1)
The following counter randomly selects values from 1 to 200 without replacement. All items are replaced after 10 blocks or after all of them have been selected.
/ select = noreplace(1-200)
/ resetinterval = 10
