Although the unaware-LNS group was stricter than the aware-LNS group in the third test, the unaware-LNS group
was marginally more lenient than the aware-LNS group in the first. An important distinction between the first and third tests,however, is that the biased feedback manipulation was successful for both the aware and unaware groups in the first test,but only for the unaware group in the third, which is suggestive of relative success for our manipulations in the first, but not in the third, test. Considerable individual variability exists in criterion shifting, potentially due to factors ranging from task strategy to personality (Aminoff et al. 2012; Han, 2009). Individual differences could have in part contributed to some of the differences seen in the first test between the aware-LNS
and unaware-LNS participants. Although random assignment to the LNS and SNL groups should in part control for this, it would be worthwhile to assess how differences in personality and task strategy, as well as in generalized suspicion of deception, contribute to how social sources influence adaptive criterion learning.
