No pain, no gains: Negative mood leads to process gains in idea-generation groups.

Research has consistently demonstrated that individuals tend to outperform groups on idea-generation tasks (e.g., Mullen, Johnson, & Salas, 1991). However, mood states have the capacity to alter the coordination and motivation of group members, leading to performance gains or performance losses. In this experiment, individuals and 3-person groups generated slogans for a fictitious company after experiencing a positive or negative mood induction. Contrary to previous research, negative mood groups in our study actually generated slogans that were more creative than those produced by negative mood individuals. No differences emerged for positive individuals and groups. In the negative conditions, the effect of level of analysis (individual vs. group) on creativity was mediated by persistence on the slogan-generation task. Results are presented in the context of feelings-as-information (N. Schwarz & G. L. Clore, 1988). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Contagious Leader: Impact of the Leader's Mood on the Mood of Group Members, Group Affective Tone, and Group Processes.

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 positive and less negative mood, and (b) groups had a more positive and a less negative affective tone. The authors also found that groups with leaders in a positive mood exhibited more coordination and expended less effort than did groups with leaders in a negative mood. Applied implications of the results are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Shifting moods, wandering minds: Negative moods lead the mind to wander.

This study examined the effect of mood states on mind wandering. Positive, neutral, and negative moods were induced in participants prior to them completing a sustained attention task. Mind wandering was measured by using the frequencies of both behavioral lapses and retrospective indices of subjective experience. Relative to a positive mood, induction of a negative mood led participants to make more lapses, report a greater frequency of task irrelevant thoughts, and become less inclined to reengage attentional resources following a lapse. Positive mood, by contrast, was associated with a better ability to adjust performance after a lapse. These results provide further support for the notion that a negative mood reduces the amount of attentional commitment to the task in hand and may do so by enhancing the focus on task irrelevant personal concerns.

Stereotype Threat and Performance: How Self-Stereotypes Influence Processing by Inducing Regulatory Foci.

The authors hypothesized that activated self-stereotypes can influence the strategies of task solution by inducing regulatory foci. More specifically, positive self-stereotypes should induce a promotion focus state of eagerness, whereas negative stereotypes should induce a prevention focus state of vigilance. Study 1 showed that a negative ascribed stereotype with regard to task performance leads to better recall for avoidance-related statements whereas a positive stereotype leads to better recall for approach-related statements. In Studies 2 and 3, both an experimental manipulation of group performance expectation and the preexisting stereotype of better verbal skills in women than in men led to faster and less accurate performance in the positive as compared with the negative stereotype group. Studies 4 and 5 showed that positive in-group stereotypes led to more creative performance whereas negative stereotypes led to better analytical performance. These results point to a possible mechanism for stereotype-threat effects. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Positive mood + action = negative mood + inaction: Effects of general action and inaction concepts on decisions and performance as a function of affect.

General action and inaction concepts have been shown to produce broad, goal-mediated effects on cognitive and motor activity irrespective of the type of activity. The current research tested a model in which action and inaction goals interact with the valence of incidental moods to guide behavior. Over four experiments, participants' moods were manipulated to be positive (happy), neutral, or negative (angry or sad), and then general action, inaction, and neutral concepts were primed. In Experiment 1, action primes increased intellectual performance when participants experienced a positive (happy) or neutral mood, whereas inaction primes increased performance when participants experienced a negative (angry) mood. Including a control-prime condition, Experiments 2 and 3 replicated these results measuring the number of general interest articles participants were willing to read and participants' memory for pictures of celebrities. Experiment 4 replicated the results comparing happiness with sadness and suggested that the effect of the prime's adoption was automatic. Overall, the findings supported an interactive model by which action concepts and positive affect produce the same increases in active behavior as inaction concepts and negative affect.

Informational mood impact on effort-related cardiovascular reponse: The diagnostic value of mood counts.

Drawing on the mood-behavior model (G. H. E. Gendolla, 2000), 2 experiments examined moods' informational impact on effort-related cardiovascular response. After being induced into positive versus negative moods, participants performed a memory task (Experiment 1) or a letter-cancellation task (Experiment 2). Half the participants received a cue that their mood could have been manipulated. As expected, both studies found stronger reactivity of systolic blood pressure in a negative mood than in a positive mood when no cue was provided. This effect diminished in the cue conditions. Additionally, achievement corresponded to systolic blood pressure reactivity (Experiment 1), the cue manipulation had no effect on mood, and mood had a congruency effect on subjective task difficulty in the no-cue conditions (Experiment 2).

The informational impact of mood on effort mobilization: A study of cardiovascular and electrodermal responses.

The impact of mood on effort quantified as autonomic adjustments was investigated in an experiment. The authors induced positive versus negative moods with either 1 of 2 mood induction procedures (music versus autobiographical recollection) that differed in the extent of required effort. Then participants performed an achievement task after demand appraisals were made. Results were as predicted. During the mood inductions, autonomic reactivity (systolic blood pressure [SBP], diastolic blood pressure, heart rate, skin conductance responses) was stronger in the relatively effortful recollection conditions than in the relatively effortless music conditions. Mood valence had no impact here. But in the context of task performance, the authors found (a) mood congruency effects on the demand appraisals that reflected subjectively higher demand in a negative than in a positive mood, and (b) stronger SBP reactivity in a negative mood compared with a positive mood. Furthermore, SBP reactivity during task performance was correlated with achievement. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Positive mood and executive function: Evidence from Stroop and fluency tasks.

Contrasting predictions have been made about the effects of positive mood states on the performance of frontal lobe tests that tap executive functions such as inhibition, switching, and strategy use. It has been argued that positive mood is likely to improve some cognitive processes, particularly those dependent on the frontal cortex and anterior cingulate of the brain. However, there is some evidence that happy mood may impair executive functioning. The current experiments investigated the effects of positive mood on Stroop and fluency tests, which are frequently used to assess executive function. Positive mood impaired performance on a switching condition of the Stroop test, but improved performance on a creative uses test of fluency. The effect of positive mood on an executive task may therefore depend on whether a task is inherently motivating or is impaired by diffuse semantic activation.

Promoting creativity in temporary problem-solving groups: The effects of positive mood and autonomy in problem definition on idea-generating performance.

The current study examined the effect of mood and autonomy in problem definition on the idea-generating performance of temporary workgroups. Groups (N=54) were randomly assigned to a mood (positive vs neutral) and autonomy (high vs low) condition and asked to brainstorm ways to improve university student life. It was found that positive mood increased the originality of ideas and that problems that provided low autonomy led to a greater number of ideas. Mood and autonomy interacted to affect group satisfaction. Furthermore, positive mood led to the identification of more important domains for improvement in the high-autonomy condition. Implications for future research using temporary problem-solving groups are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Subjective and Reinforcing Effects of Smoking During Negative Mood Induction.

Two notions strongly held by many smokers are that negative mood increases smoking behavior and that this increase is due to the ability of smoking to alleviate negative affect. This study used a modified mood induction procedure to examine both the impact of smoking on induced mood, as well as the effect of induced mood on actual smoking behavior. Forty-eight smokers were randomly assigned to a smoking or a water-drinking comparison group. Each participant attended 3 sessions during which 1 of 3 mood states (positive, negative, or neutral) was induced. Contrary to expectation, smoking did not attenuate negative affect. However, negative mood induction subsequently quickened latency to smoke and increased number of puffs consumed ad lib. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affect and Job Satisfaction: A Study of Their Relationship at Work and at Home.

The authors investigated 2 broad issues: (a) across- and within-individual relationships between mood and job satisfaction and (b) spillover in moods experienced at work and at home. Using an experience-sampling methodology, they collected multisource data from a sample of 74 working individuals. Multilevel results revealed that job satisfaction affected positive mood after work and that the spillover of job satisfaction onto positive and negative mood was stronger for employees high in trait-positive and trait-negative affectivity, respectively. Results also revealed that the effect of mood at work on job satisfaction weakened as the time interval between the measurements increased. Finally, positive (negative) moods at work affected positive (negative) moods experienced later at home. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Negative Mood, Self-Focused Attention, and the Experience of Physical Symptoms: The Joint Impact Hypothesis.

A joint impact hypothesis on symptom experience is introduced that specifies the role of negative mood and self-focus, which have been considered independently in previous research. Accordingly, negative affect only promotes symptom experience when people simultaneously focus their attention on the self. One correlational study and 4 experiments supported this prediction: Only negative mood combined with self-focus facilitated the experience (see the self-reports in Studies 1, 2a, & 2b) and the accessibility (lexical decisions, Stroop task in Studies 3 & 4) of physical symptoms, whereas neither positive mood nor negative mood without self-focus did. Furthermore, the joint impact of negative mood and self-focused attention on momentary symptom experience remained significant after controlling for the influence of dispositional symptom reporting and neuroticism.

Clearing the mind: A working memory model of distraction from negative mood.

The present research examined whether and how loading working memory can attenuate negative mood. In three experiments, participants were exposed to neutral, weakly negative, or strongly negative pictures followed by a task and a mood scale. Working memory demands were varied by manipulating task presence (Study 1), complexity (Study 2), and predictability (Study 3). Participants in all three experiments reported less negative moods in negative trials with high compared to low working memory demand. Working memory demands did not affect mood in the neutral trials. When working memory demands were high, participants no longer reported more negative moods in response to strongly negative pictures than to weakly negative pictures. These findings suggest that loading working memory prevents mood-congruent processing, and thereby promotes distraction from negative moods.

Are moods motivational states? A study on effort-related cardiovascular response.

Based on the mood-behavior-model (Gendolla, 2000), this study tested the idea that moods only have effects on effort mobilization in settings that directly call for this and in which people can thus use their moods as task-relevant information. Fifty university students were randomly assigned to a 2 (Mood: negative vs. positive) × 2 (Memorizing: intentional vs. incidental) × 2 (Time: mood induction vs. task performance) mixed model design. Effort mobilization was operationalized as systolic blood pressure (SBP) reactivity. As expected, in the intentional-memorizing condition, SBP reactivity was stronger in a negative mood than in a positive mood. Mood had no impact in the incidental-memorizing condition, which did not call for effort mobilization. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Inclusion-exclusion of positive and negative past selves: Mood congruence as information.

The current research challenges the widespread truism that recalling a positive self necessarily increases self-esteem, whereas recalling a negative self necessarily decreases self-esteem. Four experiments demonstrate that chronically happy people show a relative increase in self-esteem by recalling either a positive or a negative self. Chronically sad people, however, show a relative decrease in self-esteem by recalling either a positive or a negative self. These effects are due to divergent perceptions of mood congruence between the recalled self and the current self. Specifically, happy people perceive high mood congruence between a recalled positive self and the current self but low mood congruence between a recalled negative self and the current self. In contrast, sad people perceive high mood congruence between a recalled negative self and the current self but low mood congruence between a recalled positive self and the current self. Independent of chronic mood, mood congruence leads to perceptions of temporal recency, whereas mood incongruence leads to perceptions of temporal distance. In line with the inclusion-exclusion model of social judgment, perceived temporal recency elicits assimilation effects on self-esteem, whereas perceived temporal distance elicits contrast effects on self-esteem.

Depression moderates smoking behavior in response to a sad mood induction.

Stress and anxiety have been shown to increase smoking motivation. There is limited experimental data on depressed or sad mood and smoking. This study investigated the effects of two induced moods on smoking behavior. Depression scores were examined as a potential moderator and mood changes were tested as a potential mediator. Smokers (N = 121) were randomly assigned to receive either a sad induction or a neutral induction via standardized film clips. Among participants with higher depression scores, smoking duration and the number of cigarette puffs were greater in response to the sad condition. There was also a marginal interactive effect on the change in expired air carbon monoxide among this subsample; however, no differences in smoking latency or craving were observed. Changes in positive mood partially mediated the effect of condition on smoking behavior among participants with high depression scores. There was no modifying effect of gender or mediating effect of negative mood changes. The results provide preliminary support that decreases in positive mood may have a greater influence on smoking behavior among depression-prone smokers than less psychiatrically vulnerable smokers.

Be better or be merry: How mood affects self-control.

In 6 studies, the authors tested whether the effect of mood on self-control success depends on a person's accessible goal. We propose that positive mood signals a person to adopt an accessible goal, whereas negative mood signals a person to reject an accessible goal; therefore, if a self-improvement goal is accessible, happy (vs. neutral or unhappy) people perform better on self-control tasks that further that goal. Conversely, if a mood management goal is accessible, happy people abstain from self-control tasks because the tasks are incompatible with this goal. This pattern receives consistent support across several self-control tasks, including donating to charity, demonstrating physical endurance, seeking negative feedback, and completing tests.

The differential effects of mood on age differences in the correspondence bias.

The present study found that age-related differences in the correspondence bias were differentially influenced by induced mood. Young and older adults completed an attitude-attribution task after having been induced to experience a positive, neutral, or negative mood. Although negative moods intensified age-related differences in the correspondence bias, young and older adults were equally susceptible to the correspondence bias when in a positive mood. In addition, induced mood differentially influenced the attributional confidence of young and older adults. Whereas negatively induced young adults were less confident than positively induced young adults in their attributions, negatively induced older adults were more confident than positively induced older adults in their attributions. Findings are discussed in terms of how positive and negative moods operate differently in motivating young and older adults' attributional judgments.

A Double Dissociation Between Mood States and Personality Traits in the Anterior Cingulate.

Neuroticism and extraversion are personality traits associated with negative and positive mood states, respectively, confounding trait and state factors that may affect brain responses to emotional stimuli. The authors dissociated these factors using fMRI and the emotional Stroop attention task: Anterior cingulate (AC) response to positive stimuli varied as a function of personality trait, but not mood state, whereas AC response to negative stimuli varied as a function of mood state, but not personality trait. Negative mood, but not personality trait, also increased the functional connectivity between AC and other regions. Variance in AC activation can thus be ascribed to an intersubject variable (extraversion) when responding to positive stimuli and an intrasubject variable (mood) when responding to negative stimuli. The former may explain stable differences between extraverts and introverts. The latter may provide an adaptive mechanism to expand an individual's dynamic range in response to potentially dangerous or threatening stimuli.

The effects of adult aging and induced positive and negative mood on planning.

Changes in executive functions have been found in older adults and also in young adults experiencing positive or negative mood states. The current study investigated the hypothesis that older adults would show greater executive function impairment following mood induction than young adults. Ninety-six participants (half aged 19-37, half aged 53-80) completed a neutral, positive, or negative mood induction procedure, followed by the Tower of London planning task. Significant interactions were found between age and mood such that older adults showed greater planning impairment than young adults in both the positive and negative mood conditions. Emotionally salient events occurring before testing may interfere with executive function in older adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
