learn a list of words while they have a cold might remember more words associated with their illness such as "tissue" or "congestion" when later asked to recall the words learned. Researchers have since been conducting experiments to unearth the truth about mood-dependent memory, though it remains difficult to completely eliminate unreliability from such studies. Some studies have investigated the existence of mood-dependent memory, especially in individuals with bipolar disorder who generally vacillate over time between mood extremes, specifically depression and mania. 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. 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. However, researchers did not find a similar effect for verbal tasks. Because the two studies do not agree on the effects of mood in regard to verbal recall tasks, further research is needed to clarify the existence of mood-dependent memory on both verbal and visual recall tasks as well as to investigate mood-dependent memory in those suffering from other mood disorders or individuals without mood disorders of any kind. In 1979 a study was conducted on a man named Jonah who suffered from Multiple Personality Disorder. While asked a series of questions of various subject matter, it wasn't until he was asked personal and emotional questions that his alternate personalities seemed to surface. Each "personality" appeared to be completely distinct from the next. When the study was over and Jonah was asked what he remembered the day before, he could only remember the questions he was asked prior to the surfacing of his alternative personalities, before being asked emotionally saturated questions. While multiple personality disorder is a very complex subject aside from that of simply state dependent memory, it is possible that the varying levels of memory each personality experienced had some relationship with mood dependent memory. Pain In an experiment, subjects were asked to memorize a list of words (some of which were pain related while others not), then either submerged their hand in warm or
