Table Seven.
Testing the significance of deviation from chance levels for cue strings of length 8. The strongest evidence for above chance performance lies at the longer SOAs and the most recent positions in the list (n-back 0,1, 2). At SOA 200, there is some evidence for a weak primacy effect as well as a recency effect.
