The resetinterval attribute determines how many blocks should be run before a counter's randomly selection pool should be reset.
<counter> <defaults> <picture> <port> <sound> <text> <video> <xid>
Resetting the counter causes all items that have been selected to be returned to the selection pool. For selection with replacement, resetting the counter has no effect. By default, Inquisit resets counters after each block. This attribute is useful in cases where an experiment performs random selection without replacement over more than one block.
The following trial presents a beep at 2000 hz.
<trial adjustinterval>
/ ontrialbegin = [text.target.resetinterval = 1]
/ stimulustimes = [1=systembeep]
/ validresponse = (anyresponse)
</trial>
