The present study examined the effects of leaders' mood on (a) the mood of individual group members, (b) the affective tone of groups, and (c) 3 group processes: coordination, effort expenditure, and task strategy. On the basis of a mood contagion model, the authors found that when leaders were in a positive mood, in comparison to a negative mood, (a) individual group members experienced more p...

Although mood has a direct impact on mental and physical health, our understanding of the mechanisms underlying mood regulation is limited. Here, I propose that there is a direct reciprocal relation between the cortical activation of associations and mood regulation, whereby positive mood promotes associative processing, and associative processing promotes positive mood. This relation might ste...

In the present study we test the hypothesis that the effect of mood congruence in autobiographical recall is underlain by mood. Thirty-eight female participants were subjected to positive, negative and neutral mood inductions, and then asked to recall three personal memories. Participants’ mood was assessed using self-report questionnaires and by electromyograph (EMG) measurements of corrugator...

BACKGROUND Retrieval of opposite mood autobiographical memories serves emotion regulation, yet the factors influencing this ability are poorly understood. METHODS Three studies examined the effect of mood valence (sad vs. happy) and degree of emotional engagement on fluency of mood incongruent retrieval by manipulating emotional engagement and examining the effect of emotional film clips on t...

Previous research has shown that people solve insight or creative problems better when in a positive mood (assessed or induced), although the precise mechanisms and neural substrates of this facilitation remain unclear. We assessed mood and personality variables in 79 participants before they attempted to solve problems that can be solved by either an insight or an analytic strategy. Participan...

Visual emotion word processing has been in the focus of recent psycholinguistic research. In general, emotion words provoke differential responses in comparison to neutral words. However, words are typically processed within a context rather than in isolation. For instance, how does one's inner emotional state influence the comprehension of emotion words? To address this question, the current s...

The mood disorders major depressive disorder and bipolar disorder are prevalent, are inadequately treated, and little is known about their etiologies. A better understanding of the causes of mood disorders would benefit from improved animal models of mood disorders, which now rely on behavioral measurements. This review considers the limitations in relating measures of rodent behaviors to mood ...

Influenced by Bower (Am. Psychol. 36, 129-148, 1981) and Lang (Anxiety and the Anxiety Disorders, Erlbaum, Hillsdale, N.J., 1985), we tested three hypotheses concerning anxious mood and memory: (1) the mood state dependent hypothesis which states that memory retrieval will be greater when mood at encoding and at recall are the same than when they are different: (2) the encoding mood congruent h...

Experimental mood manipulations and functional magnetic resonance imaging (fMRI) provide a unique opportunity for examining the neural correlates of mood-congruent memory formation. While prior studies in mood-disorder patients point to the medial temporal lobe in the genesis of mood-congruent memory (MCM) bias, the interaction between mood and emotional memory formation has not been investigat...

Three studies investigated the influence of mood states on the processing of positive and negative information regarding caffeine consumption and on the impact of this information on one's mood, attitudes, and intentions. The results were consistent with the predictions of the mood-as-a-resource hypothesis: First, the induction of positive mood in high (compared with low) caffeine consumers enh...
