Motivation to regulate mood as a mediator between state extraversion and pleasant-unpleasant mood

This experience sampling study investigated whether state extraversion (i.e., momentary extraverted behavior) is positively associated with pleasant affect within persons and whether mood regulation motivation mediates this relationship. Seven times per day for one week, 162 participants reported on their state extraversion, pleasant-unpleasant mood, and mood regulation intention. Higher state extraversion was related to more pleasant mood, and this within-persons relationship held for 89% of individuals. Analyses with lagged predictors revealed that state extraversion predicted an increase in pleasant mood from one occasion to the next. Dispositional extraversion did not moderate the within-persons relationship. Hedonic mood regulation intention mediated the relation between state extraversion and pleasant-unpleasant mood. The findings support a self-regulation explanation of the extraversion-pleasant affect link.     

Affect and automatic mood maintenance

The hedonic contingency model (HCM; Wegener & Petty, 1994) states that individuals have learned to seek out positive activities while in a happy mood in order to maintain or elevate that mood. We argue that this tendency may become overlearned and, thus, automated. More specifically, the experience of a happy mood was predicted to automatically activate the mood-maintenance tendency proposed by the HCM. Participants induced into happy, sad, or neutral moods ranked their preferences for future activities that were nonconsciously associated with either a positive or negative valence. Supporting the notion of automatic mood maintenance, happy participants appeared to evaluate the affective qualities of the future activities and base their preferences on this evaluation without realizing that they were doing so. Theoretical implications of this finding are discussed.     

Effects of induced and naturalistic mood on the temporal allocation of attention to emotional information

Building upon recent findings that affective states can influence the allocation of spatial attention, we investigate how state, trait and induced mood are related to the temporal allocation of attention to emotional information. In the present study, 125 unscreened undergraduates completed a modified rapid serial visual presentation task designed to assess the time course of attention to positive and negative information, comparing a neutral baseline mood induction to either a positive or negative mood induction. Induced negative mood facilitated attentional engagement to positive information while decreasing attentional engagement to negative information. Greater naturally occurring negative state mood was associated with faster or more efficient disengagement of attention from negative information in the presence of manipulated negative mood, relative to baseline. The engagement findings were inconsistent with our mood-congruence hypotheses and may be better explained by mood repair or affective counter-regulation theories. In contrast, the disengagement findings for state mood were somewhat consistent with our mood-congruence hypotheses. The relationship between mood and attention to emotional information may differ depending on the combination of attentional mechanism (engagement versus disengagement), aspect of mood (state, trait or induced), stimulus valence (positive versus negative) and timescale (early versus late) under investigation.     

Reduced specificity of autobiographical memories following a negative mood induction

Reduced autobiographical memory specificity (AMS) to emotional and neutral cue words appears to be a stable cognitive marker of clinical depression. For example, reduced AMS is present in remitted/recovered depressed patients and shows no reliable relationship with current levels of depressed mood in correlational studies. The present study examined whether reduced AMS could be induced in healthy volunteers with no history of depression, using a negative mood manipulation and whether levels of AMS and induced mood were positively correlated. Results showed a reduction in AMS following negative mood induction, compared to a neutral induction, whereas positive mood induction had no effects on AMS. Furthermore, lower happiness following the induction phase correlated positively with reduced AMS, and the extent of happiness reduction from pre- to post-induction correlated positively with reduction in AMS. These results suggest that AMS is, at least in part, a function of current emotion state. The implications for the literature on AMS as a stable marker of clinical depression are discussed.     

The relationship between self-report mood and personality

Past research pertaining to personality and mood has been concerned with the relationship between specific personality traits and specific mood states. The present examines the relationship between self-report measures of personality and mood. University students (82 males, 118 females), completed a personality questionnaire consisting of 20 personality bipolar adjectives and a mood inventory measuring six mood dimensions. Factor analysis of the personality adjectives revealed four factors, which were then correlated with the mood scales. Results of this analysis revealed significant correlations between the personality factors and mood dimensions suggesting that personality is related to some aspects of mood.     

In the mood to face the facts: When a positive mood promotes systematic processing of self-threatening information

Two experiments tested the hypothesis that a positive mood can increase attendance to, and systematic processing of, threatening health information, particularly when the information is self-relevant. In Study 1, a positive mood increased differentiation between strong and weak arguments in a threatening health message about RSI only for participants who had received false feedback regarding their high vulnerability to RSI. Mood had no effects under conditions of low vulnerability. In Study 2, a positive mood speeded up responses to self-threatening words—compared with neutral words—for smokers who had just read a threatening health message about smoking. The authors conclude that fostering a positive mood may promote attendance to and systematic processing of information that threatens the self, and hence contribute to the success of health campaigns targeted at individuals who are vulnerable to specific health risks.

Impact of elicited mood on movement expressivity during a fitness task

The purpose of the present study was to evaluate the impact of four mood conditions (control, positive, negative, aroused) on movement expressivity during a fitness task. Motion capture data from twenty individuals were recorded as they performed a predefined motion sequence. Moods were elicited using task-specific scenarii to keep a valid context. Movement qualities inspired by Effort-Shape framework (Laban & Ullmann, 1971) were computed (i.e., Impulsiveness, Energy, Directness, Jerkiness and Expansiveness). A reduced number of computed features from each movement quality was selected via Principal Component Analyses. Analyses of variance and Generalized Linear Mixed Models were used to identify movement characteristics discriminating the four mood conditions. The aroused mood condition was strongly associated with increased mean Energy compared to the three other conditions. The positive and negative mood conditions showed more subtle differences interpreted as a result of their moderate activation level. Positive mood was associated with more impulsive movements and negative mood was associated with more tense movements (i.e., reduced variability and increased Jerkiness). Findings evidence the key role of movement qualities in capturing motion signatures of moods and highlight the importance of task context in their interpretations.     

Understanding the relationship between mood and creativity: A meta-analysis

A meta-analysis of 62 experimental and 10 non-experimental studies was conducted to evaluate the positive-mood-enhances-creativity generalization. While the results demonstrate that positive mood enhances creativity, the strength of that effect is contingent upon the comparative or referent mood state (i.e., neutral or negative mood) as well as the type of creative task. Further, the pattern of effect sizes supports a curvilinear relationship between affective intensity and creative performance. In general, a contextual perspective of mood–creativity relations is supported.     

Assessing the effectiveness of drawing an autobiographical memory as a mood induction procedure in children

The objective of our study was to examine the effectiveness of a new version of the autobiographical recall procedure (i.e., drawing a happy personal event) in eliciting a positive mood in 6-, 8-, and 10-year-old children and to compare the drawing condition to the more classical telling condition. The mood of children was assessed before and after induction using the Self-Assessment Manikin (SAM) and across the two emotional dimensions of valence and arousal. The results showed that the drawing condition was as effective as the telling condition for inducing a positive mood. Furthermore, in the drawing condition, children reported feeling calmer than in the telling condition, suggesting that drawing was more likely to help children regulate their emotional state. The drawing procedure could be used in future research aiming to induce positive moods in school-aged children, to help further investigate the relationship between cognition and emotion.     

Context effects in marketing practice: the case of mood

The role of individuals' affective state on information processing and decision making has attracted the attention of researchers in the social sciences. Building on the findings reported in the literature, the authors examine the effects of mood on marketing practice. Implications for advertising practices as well as the potential manipulation of elements of the physical store/retail environment (atmospherics) in which consumers operate in order to affect behaviour are discussed.

Attention,mindwandering, and mood

We tested the hypothesis that mindwandering and external distraction are both manifestations of a common state of reduced attention focus, and examined how both relate to reported level of happiness. We conducted real-time sampling of people’s experience of mindwandering, irrelevant distraction (e.g. by music, phone, etc.), and happiness levels, in two studies with 524 people undertaking common daily-life activities. All irrelevant external distractions were positively correlated with mindwandering. Indeed mindwandering duration could be predicted from the reported duration of external distraction, when controlling for a range of background variables. An exploratory factor analysis of mindwandering and distraction reports suggested a single underlying construct. In addition, duration of irrelevant distraction by both mobile phones and mindwandering was significantly associated with reduced reported levels of happiness. The results are consistent with the hypothesis that that a state of reduced attention focus underlies both mindwandering and distractibility and clarify the link with happiness.     

Assessment of mood states: Biases in single-administration assessments

Rasmussen, Jeffrey, Willingham, and Glover (1994) demonstrated that single-administration values derived from the Profile of Mood States (POMS) were biased estimates oftypical mood state. Like the previous study, the present study investigated whether single-administration POMS scores would be similar to average POMS scores derived from multiple administrations. In addition, in this investigation, single-administration instructions directed respondents to estimatetypical mood over a period of time that coincided with the time and duration of the multiple administrations. Subjects rated mood states during two single-administration settings, one before and one just after a multiple administration period. For both single-administration assessments, subjects rated mood relative to “How you have felt for the past 3 days, including today?” During the multiple-administration assessment, subjects rated mood six times a day for 3 days as prompted by preprogrammed wrist monitors. Results were consistent with earlier findings by identifying the bias in single-administration assessments. Initial single-administration values were significantly higher than both the averaged multiple-administration values and the second single-administration scores. These results support the contention that single-administration values from the POMS may provide biased estimates oftypical mood states.     

Cognitive reactivity to sad mood: structure and validity of a new measure.

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 Components Analysis, 26 items were retained, which comprised four factors with good psychometric properties: Negative Self-Evaluation; Acceptance/Coping; Indifference; and Harm Avoidance. In a sample of 48 college students, LEIDS scores--particularly Negative Self-Evaluation and Harm Avoidance--were rather strong predictors of cognitive reactivity in a mood induction procedure. In contrast, baseline depression and baseline cognitive dysfunction did not predict cognitive reactivity. It is concluded that the LEIDS is a promising measure of cognitive reactivity, and that clinical studies need to be carried out to test its ability to predict relapse of depression.     

Positive mood, attribution, and the illusion of familiarity

We investigated the positivity-cues-familiarity effect and the hypothesis that it is caused by a misattribution of positivity to a sense of familiarity. Participants were put in a positive or neutral mood state, and then either did or did not complete a mood-manipulation check question. Participants then rendered old/new judgments of stimuli to which they allegedly had been subliminally exposed. When participants did not complete the mood-manipulation check question, and thus the source of their affect was unclear, they showed the positivity-cues-familiarity effect: those in a positive mood identified more of the stimuli as old than did those in a neutral mood. However, those who had completed the mood-manipulation check question, and for whom the source of their affect was obvious, did not show the positivity-cues-familiarity effect. These findings support the notion that a misattribution process is responsible for the positivity-cues-familiarity effect.     

Towards a computational theory of experience

A standing challenge for the science of mind is to account for the datum that every mind faces in the most immediate – that is, unmediated – fashion: its phenomenal experience. The complementary tasks of explaining what it means for a system to give rise to experience and what constitutes the content of experience (qualia) in computational terms are particularly challenging, given the multiple realizability of computation. In this paper, we identify a set of conditions that a computational theory must satisfy for it to constitute not just a sufficient but a necessary, and therefore naturalistic and intrinsic, explanation of qualia. We show that a common assumption behind many neurocomputational theories of the mind, according to which mind states can be formalized solely in terms of instantaneous vectors of activities of representational units such as neurons, does not meet the requisite conditions, in part because it relies on inactive units to shape presently experienced qualia and implies a homogeneous representation space, which is devoid of intrinsic structure. We then sketch a naturalistic computational theory of qualia, which posits that experience is realized by dynamical activity-space trajectories (rather than points) and that its richness is measured by the representational capacity of the trajectory space in which it unfolds.     

Towards a theory of intention revision

Although the change of beliefs in the face of new information has been widely studied with some success, the revision of other mental states has received little attention from the theoretical perspective. In particular, intentions are widely recognised as being a key attitude for rational agents, and while several formal theories of intention have been proposed in the literature, the logic of intention revision has been hardly considered. There are several reasons for this: perhaps most importantly, intentions are very closely connected with other mental states—in particular, beliefs about the future and the abilities of the agent. So, we cannot study them in isolation. We must consider the interplay between intention revision and the revision of other mental states, which complicates the picture considerably. In this paper, we present some first steps towards a theory of intention revision. We develop a simple model of an agent’s mental states, and define intention revision operators. Using this model, we develop a logic of intention dynamics, and then investigate some of its properties.
