Aggressive Outcomes and Videogame Play: The Role of Length of Play and the Mechanisms at Work

We conducted three experiments to rectify methodological limitations of prior studies on selective exposure to music and, thereby, clarify the nature of the impact of sad mood on music preference. In all studies, we experimentally manipulated mood (sad vs. neutral in Experiments 1 and 2; sad vs. neutral vs. happy in Experiment 3) and then assessed participants' preferences for expressively happy versus sad musical selections. To further help illuminate the reasons for their music preferences, we also asked participants to indicate how they believed listening to each song would affect their current emotional state as well as how appropriate they felt it would be to select a given song. Results suggested that individuals in sad moods were not reliably inclined to listen to sad songs, but rather, were strongly averse to listening to happy songs, apparently out of concern that choosing such songs would feel inappropriate. We discuss implications of these findings for theories of selective media exposure and emotion regulation.     

Effects of induced sad mood on facial emotion perception in young and older adults

Older adults perceive less intense negative emotion in facial expressions compared to younger counterparts. Prior research has also demonstrated that mood alters facial emotion perception. Nevertheless, there is little evidence which evaluates the interactive effects of age and mood on emotion perception. This study investigated the effects of sad mood on younger and older adults’ perception of emotional and neutral faces. Participants rated the intensity of stimuli while listening to sad music and in silence. Measures of mood were administered. Younger and older participants’ rated sad faces as displaying stronger sadness when they experienced sad mood. While younger participants showed no influence of sad mood on happiness ratings of happy faces, older adults rated happy faces as conveying less happiness when they experienced sad mood. This study demonstrates how emotion perception can change when a controlled mood induction procedure is applied to alter mood in young and older participants.     

Effects of induced emotional state on lexical processing in younger and older adults

The authors investigated the effects of an induced emotional mood state on lexical decision task (LDT) performance in 50 young adults and 25 older adults. Participants were randomly assigned to either happy or sad mood induction conditions. An emotional mood state was induced by having the participants listen to 8 min of classical music previously rated to induce happy or sad moods. Results replicated previous studies with young adults (i.e., sad-induced individuals responded faster to sad words and happy-induced individuals responded faster to happy words) and extended this pattern to older adults. Results are discussed with regard to information processing, aging, and emotion.

Sad Mood and Music Choice: Does the Self-Relevance of the Mood-Eliciting Stimulus Moderate Song Preference?

Recent findings regarding the influence of sad mood on music preference have been inconsistent, with some research suggesting that sadness promotes selective exposure to happy music and other work suggesting the very opposite. In three experiments, we investigated whether this discrepancy may have resulted from differences in the extent to which sadness was elicited by having participants think about personally relevant versus personally irrelevant negative events. To this end, we manipulated sad mood via a guided visualization technique in which participants were led to imagine experiencing a loss that was relevant either to their own or to an unfamiliar individual's concerns. Results revealed that irrespective of the self-relevance of the mood induction, individuals in sad, relative to happy, or neutral moods preferred to avoid expressively happy music. This aversion was partially mediated by beliefs that choosing happy music while sad would be inappropriate and thereby ineffectual in mood repair. Together, these findings contribute to resolving discrepancies in the literature and help advance understanding of the influence of mood on music choice.     

Emotional valence and arousal interact in attentional control

ABSTRACT— A recent study demonstrated that observers' ability to identify targets in a rapid visual sequence was enhanced when they simultaneously listened to happy music. In the study reported here, we examined how the emotion-attention relationship is influenced by changes in both mood valence (negative vs. positive) and arousal (low vs. high). We used a standard induction procedure to generate calm, happy, sad, and anxious moods in participants. Results for an attentional blink task showed no differences in first-target accuracy, but second-target accuracy was highest for participants with low arousal and negative affect (sad), lowest for those with strong arousal and negative affect (anxious), and intermediate for those with positive affect regardless of their arousal (calm, happy). We discuss implications of this valence-arousal interaction for the control of visual attention.     

Time flies with music whatever its emotional valence

The present study used a temporal bisection task to investigate whether music affects time estimation differently from a matched auditory neutral stimulus, and whether the emotional valence of the musical stimuli (i.e., sad vs. happy music) modulates this effect. The results showed that, compared to sine wave control music, music presented in a major (happy) or a minor (sad) key shifted the bisection function toward the right, thus increasing the bisection point value (point of subjective equality). This indicates that the duration of a melody is judged shorter than that of a non-melodic control stimulus, thus confirming that “time flies” when we listen to music. Nevertheless, sensitivity to time was similar for all the auditory stimuli. Furthermore, the temporal bisection functions did not differ as a function of musical mode.     

Effects of emotional state on lexical decision performance

The effect of emotional state on lexical processing was investigated. Subjects were randomly assigned to either a happy or sad mood condition. Emotional state was then induced by listening to 8 min of classical music previously rated to induce happy or sad moods. Response times and error rates were analyzed in a lexical decision task involving sad words, happy words, and pseudowords. Results suggest that emotion aided the participants in responding to emotion-congruent stimuli. The sad group responded faster than the happy group to sad words and the happy group responded faster than the sad group to happy words. Results are discussed with regard to information processing and emotion.     

Mood and Information Processing: When Happy and Sad Look the Same

Two studies were conducted to demonstrate that sad and happy moods can cause individuals to be similarly sensitive to the valence of observed stimuli with regard to how effortfully such stimuli are processed. In Study 1, individuals in whom a sad or happy mood had been induced unitized a behavior sequence less finely when its contents were neutral as opposed to positive. Individuals in a neutral mood state maintained a comparable level of unitization regardless of the valence of the behavior sequence. In Study 2, individuals in whom a sad or a happy mood had been induced processed the arguments in a persuasive communication more extensively when its contents were affectively uplifting rather than depressing. Sad individuals showed this pattern only if no prior affective expectation was provided. Taken together, these studies may fit with the notion that under certain conditions sad and happy individuals similarly decrease the amount of information processed from a neutral (Study 1) or depressing (Study 2), relative to a positive, stimulus.     

Misery loves company: mood-congruent emotional responding to music

We examined emotional responding to music after mood induction. On each trial, listeners heard a 30-s music excerpt and rated how much they liked it, whether it sounded happy or sad, and how familiar it was. When the excerpts sounded unambiguously happy or sad (Experiment 1), the typical preference for happy-sounding music was eliminated after inducing a sad mood. When the excerpts sounded ambiguous with respect to happiness and sadness (Experiment 2), listeners perceived more sadness after inducing a sad mood. Sad moods had no influence on familiarity ratings (Experiments 1 and 2). These findings imply that "misery loves company." Listeners in a sad mood fail to show the typical preference for happy-sounding music, and they perceive more sadness in music that is ambiguous with respect to mood.     

Emotional language processing: how mood affects integration processes during discourse comprehension

This research tests whether mood affects semantic processing during discourse comprehension by facilitating integration of information congruent with moods’ valence. Participants in happy, sad, or neutral moods listened to stories with positive or negative endings during EEG recording. N400 peak amplitudes showed mood congruence for happy and sad participants: endings incongruent with participants’ moods demonstrated larger peaks. Happy and neutral moods exhibited larger peaks for negative endings, thus showing a similarity between negativity bias (neutral mood) and mood congruence (happy mood). Mood congruence resulted in differential processing of negative information: happy mood showed larger amplitudes for negative endings than neutral mood, and sad mood showed smaller amplitudes. N400 peaks were also sensitive to whether ending valence was communicated directly or as a result of inference. This effect was moderately modulated by mood. In conclusion, the notion of context for discourse processing should include comprehenders’ affective states preceding language processing.     

Approach-avoidance responses to infant facial expressions in nulliparous women: Associations with early experience and mood induction

Infant expressions are important signals for eliciting caregiving behaviors in parents. The present study sought to test if infant expressions affect adults’ behavioral response, taking into account the role of a mood induction and childhood caregiving experiences. A modified version of the Approach Avoidance Task (AAT) was employed to study nulliparous female university students’ implicit responses to infant faces with different expressions. Study 1 showed that sad, neutral and sleepy expressions elicit a tendency for avoidance, while no tendency for approach or avoidance was found for happy faces. Notably, differences between approach and avoidance response latencies for sad faces and participants’ negative caregiving experiences were positively correlated (r = 0.30, p = 0.04, Bonferroni corrected), indicating that individuals who experienced insensitive parental care show more bias toward sad infant faces. In Study 2, we manipulated participants' current mood (inducing sad and happy mood by asking to recall a happy or sad event of their recent life) before the AAT. Results showed that sad mood enhanced the bias toward sad faces that is buffered by positive mood induction. In conclusion, these findings indicate that implicit approach avoidance behaviors in females depend on the emotional expression of infant faces and are associated with childhood caregiving experiences and current mood.     

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.     

Sad mood reduces inadvertent plagiarism: Effects of affective state on source monitoring in cryptomnesia

In two experiments, we explored the influence of affective state, or mood, on inadvertent plagiarism, a memory failure in which individuals either misattribute the source of an idea to themselves rather than to the true originator or simply do not recall having encountered the idea before and claim it as novel. Using a paradigm in which participants generate word puzzle solutions and later recall these solutions, we created an opportunity for participants to mistakenly claim ownership of items that were, in fact, initially generated by their computer ‘partner.’ Results of both experiments suggest that participants induced into a sad mood before solving the word puzzles made fewer source memory errors than did those induced into a happy mood. Results of Experiment 2 also imply that sad mood reduces some item memory errors. Implications for appraisal theories, such as the affect-as-information hypothesis, are discussed.     

When necessity is the mother of invention: Mood and problem solving

Happy moods foster the ability to think about problems in new ways, but little is known about how sad moods affect this process. This paper investigates the hypothesis that individuals in sad moods adhere to the data and might not think about problems in new ways until they receive data indicating that it is appropriate to do so. To investigate this hypothesis, participants in happy, sad, and neutral moods completed a classic mental set task (Luchins, 1942). All mood groups were able to break the mental set and to think about the problems in a new way, but mood affected when they did so. Consistent with the idea that individuals in sad moods adhere to the data, they relied on the mental set until they received evidence that it may be problematic. In contrast, individuals in happier moods were more likely to abandon the mental set on their own, rather than wait for evidence of its inadequacy. In three follow-up experiments, when the information provided by participants’ sad feelings was rendered uninformative, the mood effect disappeared. These findings are consistent with the claim that affect influences processing only when it provides information about how to proceed.     

I want to be creative: exploring the role of hedonic contingency theory in the positive mood-cognitive flexibility link

Three studies explored the role of hedonic contingency theory as an explanation for the link between positive mood and cognitive flexibility. Study 1 examined the determinants of activity choice for participants in happy, sad, or neutral moods. Consistent with hedonic contingency theory, happy participants weighted potential for creativity as well as the pleasantness of the task more heavily in their preference ratings. In Study 2, participants were given either a neutral or mood-threatening item generation task to perform. Results illustrated that happy participants exhibited greater cognitive flexibility in all cases; when confronted with a potentially mood-threatening task, happy participants were able to creatively transform the task so as to maintain positive mood and interest. Finally, Study 3 manipulated participants' beliefs that moods could or could not be altered. Results replicated the standard positive mood-increased cognitive flexibility effect in the nonmood-freezing condition, but no effects of mood on creativity were found in the mood-freezing condition. These studies indicate that the hedonic contingency theory may be an important contributing mechanism behind the positive mood-cognitive flexibility link.     

Emotional Contagion and Social Judgment

This study examined the influence of another's emotional expressions and individual differences in responsiveness to afferent feedback on attention, evaluations, and memory. In a mixed design, participants (N = 71) rated pictures following exposure to a sender in a neutral mood and then in either a happy or sad mood. Attention, ratings, and recall evidenced a bias characteristic of the sender's mood: Participants spent more time viewing happy and sad pictures following exposure to the happy and sad sender, respectively; ratings by participants exposed to the happy and sad sender were more positive and negative, respectively, and this effect was greater for those more cue-responsive; participants recalled more pictures congruent with the sender's mood and those more cue-responsive exposed to the sad sender exhibited impaired memory characteristic of the effect of sadness on memory. Findings suggest that exposure to even mild emotional expressions can influence cognition and behavior and this effect is greater for those more responsive to cues generated by afferent feedback.     

The Influence of Time Pressure on Mood‐Congruent Effects: Evaluating Products With Limited Information1

This study tested mood effects on product evaluation, varying information type and time pressure. In this experiment, happy or sad moods were induced in participants, then they were asked to evaluate products. The results showed that in the happy mood/non‐time‐pressure condition, a favorable evaluation was seen when complete information was provided compared to incomplete. However, when time pressure was induced, no such difference was observed. On the other hand, in the sad mood/non‐time‐pressure condition, there was no difference in evaluation between complete and incomplete information, but when time pressure was induced, a less favorable evaluation of products was seen under incomplete relative to complete. The results provide support for the process in which participants depend on their mood as a source of information when inferring about missing information under reduced cognitive capacity.     

Does mood state change risk taking tendency in older adults?

No study has been conducted to evaluate the influences of age differences on specific moods for risk taking tendencies. This study examined the patterns of risk taking tendencies among younger and older persons in 3 transient affective states: positive, neutral, and negative moods. By means of viewing happy, neutral, or sad movie clips, participants were induced to the respective mood. Risk taking tendencies were measured with decision tasks modified from the Choice Dilemmas Questionnaire (N. Kogan & M. A. Wallach, 1964). Consistent with the affect infusion model (J. P. Forgas, 1995), risk taking tendency was greater for those individuals who were in a happy mood than for those who were in a sad mood, for both young and older participants. However, an asymmetrical effect of positive and negative mood on risk taking tendency was identified among both the young and older participants, but in opposite directions. These results are consistent with the predictions of the negativity bias and the positivity effect found in young and older adults, respectively, and are interpreted via information processing and motivation effects of mood on the decision maker.     

Effects of children's emotional state on their reactions to emotional expressions: A search for congruency effects

Abstract

Three groups of 30 six-year-old children were tested to examine whether one's own happy or sad mood state causes a specific preference for happy or sad expressions in others, a systematic bias in the labelling of ambiguous expressions, and a selective memory for happy or sad expressions. In two of these groups, a happy or sad mood state was induced by a mental imagery procedure. The third group served as control subjects. It was found that all groups showed a distinct preference for happy faces. Happy children, however, tended to opt for extremely happy faces, whereas sad children chose mildly happy expressions. Furthermore, children (especially the children that received a happy mood induction) were inclined to interpret ambiguous expressions as being congruent with their own mood state. Finally, the “sad” group recalled fewer expressions correctly than the other two, irrespective of the nature of these expressions. Overall, the happy face was more often correctly identified than the sad one.
