The durations of negative events are overestimated when compared to the actual amount of time passed (Langer, et al, 1961; Meck, 1983). Similarly, emotionally valenced faces are temporally overestimated when compared to neutral ones (Droit-Volet, Bruno, & Niedenthal, 2004). In the current study, participants embodied emotion via mood induction prior to temporal estimation of neutrally valenced ...

Consistent evidence nowadays indicates that sleep protects declarative memory from lexical interference. However, little is known about its effect against emotional interference. In a within-subject counterbalanced design, participants learned a list of word pairs after a mood induction procedure (MIP), then slept or stayed awake during the post-learning night. After two recovery nights, half o...

Cognitive reactivity to the experimental induction of sad mood has been found to predict relapse in recovered depressed patients. The present report describes the development and test of a questionnaire that aims to measure cognitive reactivity independently from a mood induction procedure. The Leiden Index of Depression Sensitivity (LEIDS) was filled out by 198 participants. After Principal Co...

Major depressive disorder (MDD) is a recurrent mood disorder. The high rate of recurrence of MDD suggests the presence of stable vulnerability factors that place individuals with a history of major depression at an increased risk for the onset of another episode. Previous research has linked the remitted state, and therefore increased vulnerability for depressive relapse, with difficulties in t...

Mood Induction Procedures (MIPs) are designed to induce emotional changes in experimental subjects in a controlled way, manipulating variables inside the laboratory. The induced mood should be an experimental analogue of the mood that would occur in a certain natural situation. Our team has developed an MIP using VR (VR-MIP) in order to induce different moods (sadness, happiness, anxiety and re...

BACKGROUND Emotional states linked to arousal and mood are known to affect the efficiency of cognitive performance. However, the extent to which memory processes may be affected by arousal, mood or their interaction is poorly understood. METHODOLOGY/PRINCIPAL FINDINGS Following a study phase of abstract shapes, we altered the emotional state of participants by means of exposure to music that ...

Participants reporting high versus low levels of experiential avoidance as assessed by the Acceptance and Action Questionnaire (Hayes et al., 2004) were compared in their responsivity to a mood induction procedure and in their subjective reactions to resulting changes in dysphoric mood. Both groups showed equivalent changes in levels of dysphoric mood across phases of the induction procedure. A...

The present research examined the effects of pre-encoding and pre-recall induced mood on episodic memory. It was hypothesized that happy and/or angry mood prior to encoding (increasing left hemisphere activity), in tandem with fearful mood prior to recall (increasing right hemisphere activity) would be associated with superior episodic memory. It was also hypothesized that tympanic membrane mea...

Research addressing the influence of happy mood on self-focused attention has yielded inconsistent results. Some studies found that happy mood decreased self-focus relative to sad mood. Other studies did not detect a significant difference between happy and neutral mood, and still other studies found that happy mood, relative to neutral mood, increased self-focus. These investigations have pote...
