BACKGROUND Experimentally induced depressed mood is a suggested model for retarded depression. We describe the neural response associated with induced mood and the locus of the interaction between systems mediating mood and cognitive function. METHODS Normal subjects performed a verbal fluency task during induced elated and depressed mood states. Regional cerebral blood flow (rCBF) was measur...

Existing evidence suggests an association between mood, time-of-day and morningness-eveningness (M-E). Since few studies have been carried out among adolescents, in this study daily mood fluctuations were analyzed in the naturalistic school context during 2 d in order to test how chronotype and time-of-day are related to mood during the school schedule period and check if sleep length is involv...

OBJECTIVE To explore the relationship between subjective mood, folate status and homocysteine in healthy individuals. DESIGN Subjective mood assessments were completed twice daily over the course of one week using the Positive and Negative Affect Scale (PANAS). The PANAS is a validated scale which considers mood state on two distinct continua, one reflecting positive mood and the other negati...

This study examined mood and mood variation in relation to varying forms and degrees of personality disorder (PD) pathology. Mood experiences of 98 psychotropic medication-free individuals were repeatedly assessed over a 4-day period. Persons with PDs (n = 57) generally displayed neutral to moderately positive moods; however, overall mood valence was less positive when compared to those without...

Neuroimaging has identified an overlapping network of brain regions whose activity is modulated by mood and cognition. Studies of depressed individuals have shown changes in perception, attention, memory, and executive functions. This suggests that mood has a pervasive effect on cognition. Direct evidence of the effect of sad mood on cognition is surprisingly limited, however. Published studies...

Recently, an increasing attempt has been made to understand the influence of mood on socioeconomic decision-making. We tested in this study whether an unpleasant mood would lead to unfavorable decisions more frequently than a pleasant mood, and whether decisions under different moods can be explained in different ways. Healthy volunteers were assigned to either a pleasant or unpleasant mood gro...

Much is known about reactive mood changes due to unpleasant tasks or situations. This research provides evidence that recurring events may also elicit anticipatory mood changes, and that both reactive and anticipatory mood responses need to be considered when studying affective experiences and emotion regulation. Based on prevalent theories on emotion regulation, we propose that anticipatory an...
