How Long Do Mood Induction Procedure (Mip) Primes Really Last? Implications For Cognitive Vulnerability Research., Jennifer C P Gillies, David J A Dozois

BACKGROUND: Mood Induction Procedures (MIPs) are used widely in research on cognitive vulnerability to depression. Although empirical evidence supports certain MIPs as effective, little research has evaluated whether MIP-induced sad moods are sufficiently persistent. This study aimed to determine (1) how long an MIP-induced mood lasts according to commonly used operational definitions and (2) whether these findings vary according to the type of MIP used.
METHODS: Four-hundred-and-one undergraduate students were randomly assigned to one of three commonly used sad MIPs (music, memory, music+memory) or to one of three matched neutral MIPs. Mood was repeatedly measured immediately prior to and following …

BACKGROUND: According to cognitive theories of depression, more negative and less positive self-schemas are thought to play a causal role in the disorder. Existing evidence speaks to the neural substrates of self-referential processes in both healthy and depressed individuals, but little is known about how the brain relates to self-referential processing in the context of depression risk in children. We therefore studied the neural substrates of self-referential processing in never-depressed preadolescent children at high and low risk for depression based on maternal depression history.
METHODS: A total of 87 never-depressed 10-12-year-old children (29 with maternal depression) completed a self-referential encoding …

Emotion theory emphasizes the distinction between social vs non-social emotional-processing (E-P) although few functional neuroimaging studies have examined whether the neural systems that mediate social vs non-social E-P are similar or distinct. The present fMRI study of script-driven imagery in 20 women demonstrates that social E-P, independent of valence, more strongly recruits brain regions involved in social- and self-referential processing, specifically the dorsomedial prefrontal cortex, posterior cingulate/precuneus, bilateral temporal poles, bilateral temporoparietal junction and right amygdala. Functional response within brain regions involved in E-P was also significantly more pronounced during negatively relative to positively valenced E-P. Finally, the effect for …
