Arousal and mood factors in the "Mozart effect"

Some investigators of the "Mozart effect" have not controlled for the influence of differences in arousal or mood induced by treatment conditions. Studies by Rideout and colleagues reported differences in spatial reasoning after listening to a Mozart sonata compared against a relaxation instruction tape. The conditions may have affected subjects' arousal differentially, with the sonata increasing arousal and the relaxation instructions decreasing arousal, which could have affected spatial reasoning performance. Evidence is cited in support of this suggestion and indicates the importance of analyzing the influence of arousal differences in Mozart effect research.     

Effects of Violent Versus Nonviolent Video Games on Children's Arousal, Aggressive Mood, and Positive Mood

This study investigated the relationship between violent video games and children's mood. A total of 71 children aged 8 to 12 years played a paper-and-pencil game, a nonviolent video game, and a violent video game. Results indicate that arousal, as measured by heart rate and self-reported arousal, increased significantly after playing the violent video game, as compared with the other two game conditions, with girls reporting more arousal than did boys. There was no significant increase in aggressive mood scores for either boys or girls after playing the violent game. Positive mood, as measured by positive affect, showed no significant increases or decreases after playing either video game. However, positive mood, as measured by general mood, showed a significant increase after playing the violent game for both boys and girls, but only as compared with the paper-and-pencil game. Results are interpreted in terms of social learning and cognitive information processing theories of aggression.     

Considering Personal Strengths: The Effect of Three Different Methods on Mood,Arousal, and Self-Esteem1

One hundred twenty-eight college students were randomly assigned to 1 of 3 strength consideration conditions: (a) open-ended generation of strengths, (b) cued generation of strengths using 7 Divisions of Self (social, cognitive, behavioral, physical, emotional, motivational, spiritual; Dees, Dansereau, Peel, Boatler, & Knight, 1991) as cues, and (c) selection of strengths using the Tower of Strengths Activity (Sia & Czuchry, 1997). After all 3 conditions, students showed an increase in specific aspects of self-esteem and positive mood, and a decrease in global self-esteem. Students’ arousal decreased after both open-ended generation and cued generation, whereas after the selection of strengths, students’ arousal remained the same. Applications of the strength consideration activities are discussed.     

Valence and Arousal Ratings for Velten Mood Induction Statements

Participants rated 84 statements adapted from Velten's original mood induction statements—designed to induce positive and negative mood—on two dimensions of emotion (valence and arousal), using the Self Assessment Manikin (SAM) (P. J. Lang, M. M. Bradley, & B. N. Cuthbert, 1999). Fifty-two of these Velten positive, negative, and neutral statements yielded SAM valence ratings that were consistent with Velten's previous valence designation (E. Velten, 1968). Reliability analyses for the positive, negative, and neutral statements indicated a high level of internal consistency in the three statement groups. Arousal and valence ratings of the statements were positively correlated. Related issues concerning differences in rating verbal versus visual emotional stimuli and recommendations for future work to improve the validity of Velten's mood induction statements are addressed.     

Hedonic Tone,Perceived Arousal,and Item Desirability: Three Components of Self-reported Mood

Self-reports of mood are the most frequently used measure of subjective emotional experience in studies of human emotion. The present study evaluated the degree to which self-reports of mood reflect the social desirability of an affective state, rather than the hedonic tone and the level of arousal associated with such states. The study produced three main findings. First, the desirability of a mood and the hedonic quality of a mood are related, but not identical entities. Secondly, the desirability of a mood is also related to the level of arousal the mood denotes. Thirdly, desirability components are related to the self-report ratings of mood, but the ratings also reflect the hedonic tone and level of arousal describing the internal state of the respondents. Social desirability does affect the self-report ratings that are often used in emotion research, but such ratings also reflect something about the internal state of the respondents.     

The Effects of Elevated Arousal and Mood on Maximal Strength Performance in Athletes

Optimal arousal models contend that high arousal contributes to inhibited athletic performance, whereas there is reversal theory research which indicates that high positive arousal may enhance performance. To test these claims, 22 male and 6 female elite athletes were induced into high arousal telic (goal-directed) and high arousal paratelic (non goal-directed, process focussed) motivational states and tested on a standard hand strength task. Personalized guided imagery techniques and paced breathing were used to change psychological and physiological arousal. Significant increases in strength performance occurred when arousal was high and experienced as pleasant excitement in the paratelic condition (i.e., high positive arousal). Heart rate and other indicators of parasympathetic and sympathetic nervous system activity were not found to mediate between psychological arousal and performance. Where athletic performance requires maximal motor strength over a short period, performance benefits of high arousal may be maximized by restructuring motivational state.

The Influence of Feedback on Mood: Linear Effects on Pleasantness and Curvilinear Effects on Arousal

We investigated the effects of feedback (grades) on two primary mood dimensions - Pleasantness and Arousal. We hypothesized that (a) cognitive comparisons of feedback to multiple standards yield cognitive appraisals of feedback sign, and that (b) feedback sign has a linear effect on harm/benefit appraisal, which influences mood Pleasantness, and a curvilinear effect on need for action appraisal, which influences Arousal. In Study 1 (N = 281), grades (a proxy for the sign of feedback-norm discrepancy) had a linear relationship with Pleasantness and a U-shaped relationship with Arousal. In addition, subjects who received grades had higher Arousal than control subjects. Study 2 (N = 226) replicated the results of Study 1 and showed that after controlling for the relationship of grades with Pleasantness and Arousal, the sign of feedback-expectation discrepancy (a second standard) also had a linear relationship with Pleasantness and a U-shaped relationship with Arousal.     

The Mozart Effect: An Artifact of Preference

The "Mozart effect" reported by Rauscher, Shaw, and Ky (1993, 1995) indicates that spatial-temporal abilities are enhanced after listening to music composed by Mozart. We replicated and extended the effect in Experiment 1: Performance on a spatial-temporal task was better after participants listened to a piece composed by Mozart or by Schubert than after they sat in silence. In Experiment 2, the advantage for the music condition disappeared when the control condition consisted of a narrated story instead of silence. Rather, performance was a function of listeners' preference (music or story), with better performance following the preferred condition.     

Mozart Among the Theologians

The essay compares and contrasts the philosophical, theological, and aesthetic approaches to Mozart in the writings of Søren Kierkegaard's aesthete A (Either/Or, I), Karl Barth (primarily Wolfgang Amadeus Mozart), and Hans Küng (Mozart: Traces of Transcendence). Whereas Kierkegaard's A outlines a non‐religious ‘daemonic Mozart’, Barth and Küng depict two contrasting theological understandings of Mozart's music. Barth's Mozart reflects a Reformed aesthetic, with Mozart as a ‘parable’ of gospel, whereas Küng's Mozart reflects a Roman Catholic ‘sacramental’ vision of music and religious faith. The essay explores how these different visions of Mozart are shaped by both their theological and aesthetic commitments.     

The Mystery of the Mozart Effect: Failure to Replicate

The Mozart effect is the purported increase in spatial-reasoning performance immediately after exposure to a Mozart piano sonata. Several laboratories have been unable to confirm the existence of the effect despite two positive reports from the original laboratory. The authors of the original studies have provided a list of key procedural components to produce the effect. This experiment attempted to produce a Mozart effect by following those procedural instructions and replicating the procedure of one of the original positive reports. The experiment failed to produce either a statistically significant Mozart effect or an effect size suggesting practical significance. This general lack of effect is consistent with previous work by other investigators. We conclude that there is little evidence to support basing intellectual intervention programs on the existence of the Mozart effect.     

Affective Arousal as Information: How Affective Arousal Influences Judgments,Learning, and Memory

The affect‐as‐information framework posits that affect is embodied information about value and importance. The valence dimension of affect provides evaluative information about stimulus objects, which plays a role in judgment and decision‐making. Affect can also provide evaluative information about one's own cognitions and response inclinations, information that guides thinking and reasoning. In particular, positive affect often promotes, and negative affect inhibits, accessible responses or dominant modes of thinking. Affect thus moderates many of the textbook phenomena in cognitive psychology. In the current review, we suggest additionally that the arousal dimension of affect amplifies reactions, leading to intensified evaluations, increased reliance on particular styles of learning, and enhanced long‐term memory for events. We conclude that whereas valenced affective cues serve as information about value, the arousal dimension provides information about urgency or importance.     

Arousal,valence, and memory for detail

A common finding in the emotion‐memory literature is that memory is enhanced for positively arousing stimuli and negatively arousing stimuli relative to neutral stimuli. We tested the notion that post‐stimulus elaboration is responsible for these effects. Post‐stimulus elaboration refers to the process of thinking about an event (after its offset) more frequently or more in‐depth. We tested the hypothesis by presenting participants with 36 slides depicting events that varied in arousal (low and high) and valence (positive and negative). The opportunity for elaboration was manipulated by requiring participants, during the inter‐slide interval, to complete addition problems, simply view the addition problems, or view a blank slide. Cued recall memory was tested for central and background details. Based on the post‐stimulus elaboration hypothesis it was expected that the greatest memory decline would occur for the central details of negatively and positively arousing slides when participants were required to complete addition problems (i.e., a distractor task × arousal × detail interaction). Contrary to the hypothesis, we found that filling the inter‐slide interval with a distractor task decreased memory for negative stimuli compared to positive stimuli. This effect was independent of arousal. We also found that arousal increased central detail memory for positive and negative stimuli and background detail memory for positive stimuli but not for negative stimuli. This interaction was explained on the basis of pre‐attentive encoding and cue utilisation. It was concluded that in order to understand the complex relationship between emotion and memory, future studies should include, as a minimum, the variables of valence, arousal, and detail.

Sexual Arousal,Affect, and Heterosexual Attraction

Abstract

A study of residents who remained in the vicinity of Three Mile Island (TMI) immediately following the restart of the nuclear generating plant revealed that older residents employed a more emotion-focused coping style in the face of this event than did younger residents. Coping style was, however, unrelated to the level of psychological symptoms for these older residents, whereas demographic variables were related. Among younger residents, on the other hand, coping style was related to the level of psychological symptoms, whereas demographic variables were not. Among younger residents, emotion-focused coping was associated with more symptoms and problem-focused coping was associated with fewer symptoms, contradicting previous findings among TMI area residents.     

Influence of Future Choice Importance and Arousal upon the Halo Effect

Two determinants of the magnitude of the influence of anticipated choice on the halo effect are investigated: importance of future choice and arousal. Male subjects ranked photographs on positive personality traits. Half of the photographs were of persons about which they anticipated making a choice. In confirmation of the hypotheses, (a) the intercorrelation of the rankings was greater for the choice photographs than for the nonchoice photographs when the subjects anticipated an important choice, but not when they anticipated an unimportant choice; and (b) the intercorrelation was greater for the choice photographs than for the nonchoice photographs when the subjects were aroused by caffeine and uninformed as to the source of their arousal, but not when they were informed as to the source of their arousal or not aroused.
