Mood-induction research--its implications for clinical depression.
ABSTRACT Mood-induction procedures (MIPs) are increasingly being used as laboratory analogues of clinical depression. Four methods of mood induction are described: reading depressing self-referent statements: remembering past unpleasant events; listening to a taped depressing story: and failure on a task. The effects of these MIPs on affect, behaviour and related variables and parallels between these effects and clinical deficits are reviewed. The implications of MIP research for clinical depression are discussed in the light of self-awareness theory, mood effects on memory, and the inter-relationship between cognitive and somatic variables in depression.

ABSTRACT: Affect is a fundamental aspect of the human mind. An increasing number of experiments attempt to examine the influence of affect on other psychological phenomena. To accomplish this research, it is necessary to experimentally modify participants' affective states. In the present experiment, we compared the efficacy of four commonly used affect induction procedures. Participants (38 healthy undergraduate students: 18 males) were randomly assigned to either a pleasant or an unpleasant affect induction group, and then underwent four different affect induction procedures: (1) recall of an affectively salient event accompanied by affectively congruent music, (2) script-driven guided imagery, (3) viewing images while listening to affectively congruent music, and (4) posing affective facial actions, body postures, and vocal expressions. All four affect induction methods were successful in inducing both pleasant and unpleasant affective states. The viewing image with music and recall with music procedures were most effective in enhancing positive affect, whereas the viewing image with music procedure was most effective in enhancing negative affect. Implications for the scientific study of affect are discussed.Frontiers in Psychology 07/2014; 5:689. · 2.80 Impact Factor

ABSTRACT: The present article reports two experiments examining the impact of recollecting emotionally valenced autobiographical memories on subsequent working memory (WM) task performance. Experiment 1 found that negatively valenced recollection significantly disrupted performance on a supra-span spatial WM task. Experiment 2 replicated and extended these findings to a verbal WM task (digit recall), and found that both negative and positive autobiographical recollections had a detrimental effect on verbal WM. In addition, we observed that these disruptive effects were more apparent on early trials, immediately following autobiographical recollection. Overall, these findings show that both positive and negative affect can disrupt WM when the mood-eliciting context is based on autobiographical memories. Furthermore, these results indicate that the emotional disruption of WM can take place across different modalities of WM (verbal and visuo-spatial).Acta Psychologica 09/2014; 151:237–243. · 2.26 Impact Factor
