The effects of induced negative mood state on recalled autobiographical content and memory

Autobiographical memory has been theorized to serve as an adaptive function in coping with negative mood state. To gain a better understanding of whether autobiographical memory changes with negative mood state, a number of experiments examined the relative accessibility of cognitive content and ability to recall specific event memories in those who had a previous history of depression or showed some aspects of current depressive symptoms. Five separate studies involved 288 participants and examined the effects of negative mood components on autobiographical recall. Studies 1 – 4 examined the autobiographical content by cueing content using a cue word technique to evoke autobiographical memories by means of a modified version of the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986). Negative mood state was induced by Velten mood induction technique, and self-reported mood was measured using University of Wales Institute of Science and Technology Mood Adjective Checklist (UWIST-MACL; Matthews, Jones & Chamberlain, 1990) before and after mood induction. The ability to recall specific event memories was measured in Study 5 by the Sentence Completion for Events from the Past Test (SCEPT; Raes, Hermans, Williams, & Eelen, 2007). The results indicate that negative mood does influence autobiographical recall in terms of content and memory. These results indicate that autobiographical memory is a phenomenon that is in part dependent on negative mood state and in part dependent on current depressive symptoms and history of depression. Increased rumination was particularly responsive to induced negative mood state in those with current depressive symptoms. Reduced levels of activity, alertness, loss of interest and diminished pleasure are aspects of negative mood that seem to be particularly important components of mood state at the time of recall. To gain further insights into mood state effects in autobiographical recall, future directions in mood research should focus on and differentiate between the separate mood state components that are more important in bringing about changes in recalled content, especially in those with either a history of depression or showing current depressive symptoms
