In 1977, it was found that individuals with bipolar disorder performed better on a verbal association test when they were in a similar mood state to their state when the verbal associations were learned.[14] A more recent study in 2011 similarly studied a group of individual with bipolar disorder and found evidence for mood-dependent memory on a visual task (recognition of inkblots). It was observed that subjects had better recall for these inkblots when they were in the same mood state they had been in when they first saw these inkblots.
