The Role of Rhythm and Pitch in the Evaluation of Human Laughter

Human laughter vocalizations are composed of highly variable sounds. We investigated the evaluation of laughter sounds and concentrated especially on the role of two acoustic features of laughter series: specific rhythms and changes in the fundamental frequency. Experimentally modified laughter series were evaluated using listener self-report data. Participants evaluated laughter series with differences in duration (Experiment 1), or in duration and frequencies (Experiment 2) of successive elements. Serial patterns with varying parameters received good ratings that were close to those received for natural laughter. By contrast, series with a stereotyped patterning received poor ratings. In addition, we found that self-report data strongly correlated to participants' direct behavioral reactions while listening to a specific stimulus. We suggest a three-part model to describe mechanisms underlying the evaluation of laughter.     

Linguistic Labels and Categorization in Infancy: Do Labels Facilitate or Hinder?

Although it is generally accepted that labels facilitate categorization in infancy, recent evidence suggests that infants and young children are more likely to process visual input when presented in isolation than when paired with nonlinguistic sounds or linguistic labels. These findings suggest that auditory input (when compared to a no‐auditory baseline) may hinder rather than facilitate categorization. This study assessed 8‐month‐olds' (n = 191) and 12‐month‐olds' (n = 81) abilities to form categories when images were paired with nonlinguistic sounds, linguistic labels, and when presented in isolation. Overall, infants accumulated more looking when visual stimuli were accompanied by sounds or labels; however, infants were more likely to categorize when the visual images were presented without an auditory stimulus.     

Strangers meet: Laughter and nonverbal signs of interest in opposite-sex encounters

When strangers of the opposite-sex meet for the first time, both sexes are in a difficult situation. In this high risk situation, neither person knows the intention of the other, and consequently non-verbal signalling becomes the major channel for communication. Because of their higher biological risk, females should prefer less obvious tactics in order to communicate interest in a potential partner than males. The tactical task of signalling clearly, but at the same time subtly, is solved by the use of multifunctional or metacommunicative signals. In this study we propose that there is not one single meaning for any given signal. In laughing loudly we find a signal which consists of acoustical, mimical and postural information. In this way either laughter can send a this is play message or its meaning can be modified by other signals. Thus laughter, together with its accompanying body postures and movements, conveys messages that range from sexual solicitation to aversion, depending on which and how many different signals are present. Males seem to communicate interest for the female during laughter with only a few signals, such as body orientation and dominance signals. In contrast, females communicate interest via numerous signals which function as signals of bodily self-presentation and submission. In both sexes, a lack of interest is communicated through closed postures.Polly Wiessner, Jay Feierman and John Dittami have significantly helped with their ideas and have corrected what the author thought was the English language.     

Laughter in Conversation: Features of Occurrence and Acoustic Structure

Although human laughter mainly occurs in social contexts, most studies have dealt with laughter evoked by media. In our study, we investigated conversational laughter. Our results show that laughter is much more frequent than has been described previously by self-report studies. Contrary to the common view that laughter is elicited by external stimuli, participants frequently laughed after their own verbal utterances. We thus suggest that laughter in conversation may primarily serve to regulate the flow of interaction and to mitigate the meaning of the preceding utterance. Conversational laughter bouts consisted of a smaller number of laughter elements and had longer interval durations than laughter bouts elicited by media. These parameters also varied with conversational context. The high intraindividual variability in the acoustic parameters of laughter, which greatly exceeded the parameter variability between subjects, may thus be a result of the laughter context.     

Can a Click be a Word?: Infants' Learning of Non‐Native Words

Forms that are nonlinguistic markers in one language (i.e., “tsk‐tsk” in English) may be part of the phoneme inventory—and hence part of words—in another language. In the current paper, we demonstrate that infants' ability to learn words containing unfamiliar language sounds is influenced by the age and vocabulary size of the infant learner, as well as by cues to the speaker's referential intent. When referential cues were available, infants at 14 months learned words with non‐native speech sounds, but at 20 months only those infants with smaller vocabularies succeeded. When no referential cues were present, infants at both 14 and 20 months failed to learn the same words. The implications of the relation between linguistic sophistication and non‐native word learning are discussed.     

Emotional crisis communication

Organizational crises are usually highly emotional experiences for both organizations and stakeholders. Hence, crisis situations often result in emotionally charged communication between the two parties. Despite the attention of organizations and scholars to the emotions of stakeholders during crises, little is known about the effects of the emotions communicated by organizations on corporate reputations. Through the use of vignettes, this experiment reveals that besides crisis-response strategy (diminish vs. rebuild), the communicated emotion (i.e., shame and regret) has a positive effect on corporate reputation. Mediation analyses showed that this effect of communicated emotion could be explained by the public's (negative) affective as well as cognitive responses (i.e., account acceptance). This study confirms that emotional signals embedded in crisis responses may affect corporate reputations by reducing feelings of anger and by increasing the acceptance of the organizational message. In doing so, this study provides a starting point for further exploration of the effectiveness of other emotions in crisis communication.     

When Sharing a Laugh Means Sharing More: Testing the Role of Shared Laughter on Short-Term Interpersonal Consequences

Laughter is a common social behavior. Yet when, why, and how laughter may cause positive relationship change is largely unexamined, empirically. The current studies focus on shared laughter (i.e., when), drawing from theory in relationship science to emphasize the importance of conceptualizing laughter as situated within the dyadic context (i.e., why). Specifically, these studies target untested possible short-term outcomes from social interactions involving shared laughter: positive emotions, negative emotions, and perceived similarity. In turn, each are tested as possible mechanisms through which shared laughter promotes more global relationship well-being (i.e., how). A series of online and laboratory studies provide correlational and causal support for the hypothesis that shared laughter promotes relationship well-being, with increased perceptions of similarity most consistently driving this effect. Discussion focuses on the importance of considering the behavior of laughter itself, as situated within the social context, when making predictions about laughter’s relevance for social life.     

Pop Music and the Search for the Numinous: Exploring the Emergence of the “Secular Hymn” in Post-Modern Culture

A growing body of research suggests that traditional religious institutions are failing to meet the spiritual needs of their adherents, who are now abandoning traditional worship and turning to pop music to fill the void. This article defines and explores the phenomenon of the “secular hymn.” While nonreligious in nature or intent, the secular hymn is a pop song that allows the listener to experience the numinous by creating an affective state that parallels a spiritual or religious state of mind. This article outlines the phenomenon of the secular hymn in pop culture, defines its characteristics, and evaluates several pop songs against these criteria. While some secular hymns may be used in some church settings, the overall trend may exemplify the continuing erosion of traditional religion and the use of explicitly religious music in both public and private settings.     

Family Therapy … What's in a Name?

In the search for therapeutic efficacy, we vacillate from ‘certitude’ to ‘certitude’, repetitively embracing and then discarding the objects of our intellectual passion(!). The following juxtaposition of images and sounds is intended to suggest that ‘wisdom’ and ‘truth’ may derive from a more judicious and multi-layered integration of enquiry and fidelity. The idea of narrative implies not only a story but also a range of possible relationships between narrator and listener, and raises for examination the qualities of both parties. A ‘good story’ may lie as much in the probity of the relationship as in what is told or heard. It is even possible a ‘good story’ may not always be a story for ‘good’.     

Learned Labels Shape Pre‐speech Infants’ Object Representations

Infants rapidly learn both linguistic and nonlinguistic representations of their environment and begin to link these from around 6 months. While there is an increasing body of evidence for the effect of labels heard in‐task on infants’ online processing, whether infants’ learned linguistic representations shape learned nonlinguistic representations is unclear. In this study 10‐month‐old infants were trained over the course of a week with two 3D objects, one labeled, and one unlabeled. Infants then took part in a looking time task in which 2D images of the objects were presented individually in a silent familiarization phase, followed by a preferential looking trial. During the critical familiarization phase, infants looked for longer at the previously labeled stimulus than the unlabeled stimulus, suggesting that learning a label for an object had shaped infants’ representations as indexed by looking times. We interpret these results in terms of label activation and novelty response accounts and discuss implications for our understanding of early representational development.     

The effect of the still‐face paradigm on infant behavior: A cross‐cultural comparison between mothers and fathers

Most still‐face paradigm (SFP) studies have been done in Western families with infant–mother dyads. The present study investigated the SFP pattern in 123 Dutch and 63 Chinese 4‐month‐old infants with mothers and fathers. The classic SFP effect was found for positive affect and gaze in both countries. For negative affect, Chinese infants showed a different SFP pattern than Dutch infants. With fathers, infants displayed a less pronounced SFP pattern for positive affect and an increase from the still face to the reunion for negative affect. Only a minority of infants showed the expected SFP pattern across episodes. Our findings support that infant emotion expression is influenced by parent gender and cultural context. An interesting avenue for further study is the exploration of the origins of within‐ and between‐gender and culture differences in affective communication between parents and infants.     

The anxiety of affect: melodrama and South African film studies

This paper argues that the realist approach typically adopted in South African film studies reduces films to message‐bearing narratives in a way that ignores the specificity of the medium. Conversely, melodrama both as cinematic genre and as expressive register explicitly draws our attention away from issues of right representation to other neglected but essential dimensions of cinema. We argue that, far from being morally reductive or politically quietist, melodrama is a representational mode wholly appropriate to understanding the South African context including the painful stories of its apartheid past. To illustrate this broader critical point we offer an analysis of two films (of 2004) about the Truth and Reconciliation Commission (TRC) – In My Country and Forgiveness – which, we argue, can only be adequately understood if their uses of the visual and affective strategies of melodrama, which are consonant with aspects of the TRC itself, are acknowledged.     

Affect and Sexual Responsivity in Men With and Without a History of Sexual Aggression

Despite increased attention to understanding risk factors for sexual aggression, knowledge regarding the emotional and sexual arousal patterns of sexually aggressive men remains limited. The current study examined whether sexually aggressive men exhibit unique profiles of affective responsivity, in particular to negatively valenced stimuli, as well as sexual arousal patterns that differentiate them from nonaggressive men. We presented 78 young men (38 sexually aggressive; 40 nonaggressive) with a series of videos designed to induce positive, sad, or anxious affect. Affect and subjective sexual arousal were assessed following each film and erectile responses were measured continuously. Sexually aggressive men reported significantly higher levels of sexual arousal following both the positive and negative conditions as compared to nonaggressive men. Erectile responses of sexually aggressive men were significantly greater than nonaggressive men’s following the positive affect induction. Self-reported positive affect, but not negative affect, was a significant predictor of subjective sexual arousal for both groups of men. Compared to nonaggressive men, sexually aggressive men showed significantly weaker correlations between subjective and physiological sexual arousal. Findings suggest that generalized heightened propensity for sexual arousal may be a risk factor for sexually aggressive behavior.     

The Role of Humor Styles and Shared Laughter in the Postdivorce Recovery Process

ABSTRACT

Humorous communication has the potential to bolster resilient outcomes in individuals, and this could be especially true postdivorce. Framed by the resilience model and the stress buffering hypothesis, this study examined humor styles and shared laughter as coping mechanisms following divorce. Results indicate that participants (N = 89) who used self-defeating humor experienced physical stress, the time since the divorce was finalized influenced stress and rumination, and physical stress symptoms are suppressed by shared laughter with a source of social support. The implications of humor as an individual resource and shared laughter as a social resource in postdivorce resiliency are discussed.     

Reconceptualizing resistance: sociology and the affective dimension of resistance

This paper re‐examines the sociological study of resistance in light of growing interest in the concept of affect. Recent claims that we are witness to an ‘affective turn’ and calls for a ‘new sociological empiricism’ sensitive to affect indicate an emerging paradigm shift in sociology. Yet, mainstream sociological study of resistance tends to have been largely unaffected by this shift. To this end, this paper presents a case for the significance of affect as a lens by which to approach the study of resistance. My claim is not simply that the forms of actions we would normally recognize as resistance have an affective dimension. Rather, it is that the theory of affect broadens ‘resistance’ beyond the purview of the two dominant modes of analysis in sociology; namely, the study of macropolitical forms, on the one hand, and the micropolitics of everyday resistance on the other. This broadened perspective challenges the persistent assumption that ideological forms of power and resistance are the most pertinent to the contemporary world, suggesting that much power and resistance today is of a more affective nature. In making this argument, it is a Deleuzian reading of affect that is pursued, which opens up to a level of analysis beyond the common understanding of affect as emotion. I argue that an affective approach to resistance would pay attention to those barely perceptible transitions in power and mobilizations of bodily potential that operate below the conscious perceptions and subjective emotions of social actors. These affective transitions constitute a new site at which both power and resistance operate.     

Positive Emotions,Instrumental Resources,and Organizational Network Evolution: Theorizing via Simulation Research

In the workplace, people seek positive emotional experiences as well as instrumental resources while doing their work. Yet we know little about how affective micro-dynamics drive the evolution of organizational networks, influence network trajectories, and determine macro outcomes such as collective affect and overall network structure. Given the lack of theory on affective micro-dynamics and network evolution, we propose a model that includes both affective and instrumental micro-mechanisms and use simulation methods to explore evolutionary dynamics and develop new theory. The core of our model is the empirically observed tendency for people to forego the acquisition of instrumental resources to avoid a decrease in positive emotion when choosing interaction partners. We conduct “experiments” with the simulation, considering the effects of the tradeoff, dispositional affect, resource inequality, and ingroup favoritism. The results show that dispositional affect and the tradeoff have considerable effects on network trajectories, collective affect, and resource transfer. We provide new theoretical propositions about affect in organizations.     

Nasality of Infant Vocalizations Determines Gender Bias in Adult Favorability Ratings

Adults rate vocalizing 3-month-old boys as more socially favorable (pleasant, friendly, fun, likeable, cuddly, cute) than girls when they are producing syllabic sounds. Is the preference due to gender bias or to actual sex differences in the acoustical quality of early vocalizations? In Experiment 1, 59 adults rated videotaped segments of 4 vocalizing boys and 4 vocalizing girls who were dressed identically in white gowns, and labelled with a name representing their sex or a name of the opposite sex. Two infants of each sex produced syllabic sounds, and 2 produced vocalic sounds. Adults rated boys producing syllabic sounds more favorably even when the boys were labelled with the names of girls. Therefore, the preference was not due to gender bias. In Experiment 2, 3 groups of adults (N = 50, 49, and 50, respectively) each viewed and rated 1 of 3 different sets of videotaped infants. The videotapes contained segments of 8 infants (4 boys, 4 girls, 2 of each producing syllabic sounds, and 2 producing vocalic sounds); infants appeared dressed in identical white gowns and were identified only by number, not by name or sex. In addition to the social favorability ratings, adults guessed the sex of the infant. Adults rated syllabic boys more favorably even though gender was disguised, and even though their guesses of gender were no better than chance. In Experiment 3, the vocalizations of the infants who were heard in the 3 videotapes were subjected to spectrographic acoustic analysis. The acoustic quality of boys' syllabic sounds differed from that of girls' only on the feature of nasality. As expected, syllabic, as compared with vocalic, sounds of both boys and girls were similarly longer in duration and differed in frequency characteristics, but these differences were related only to sound category and not to sex. The variance in adult social favorability ratings due to sex of infant was explained by the less nasal acoustic quality of the boys' voices. These results have implications for early socialization, because we know that mothers respond more to less nasal vocalizations. These results parallel the less nasal quality of men's voices as compared with women's voices, and suggest continuities from early vocalizations to speech.     

Physiological Reactivity to Infant Crying and Observed Maternal Sensitivity

Relations between maternal sensitivity and physiological reactivity to infant crying were examined using measures of heart rate (HR) and respiratory sinus arrhythmia (RSA) in 49 mothers of second‐born infants. Using the Ainsworth Sensitivity Scale, an independent assessment of maternal sensitivity was made during maternal free play and bathing of their infants. Physiological reactivity was measured while mothers listened to three blocks of infant cry sounds in a standard cry paradigm. Mothers scoring high on sensitivity were compared to less sensitive mothers on both their physiological reactivity to the presented crying sounds and their physiological mean‐level differences. Significant interaction effects were found for both HR and RSA. Highly sensitive mothers showed a larger increase in HR and stronger RSA withdrawal in response to the first block of cry sounds compared to less sensitive mothers. Main effects showed that highly sensitive mothers had lower mean overall HR, and higher mean RSA levels across all three blocks of crying sounds compared to less sensitive mothers. RSA withdrawal and accompanying HR increases are discussed from a polyvagal perspective as indicative of a better capability in responding to infant signals of negative affect.     

Human Non-linguistic Vocal Repertoire: Call Types and Their Meaning

Recent research on human nonverbal vocalizations has led to considerable progress in our understanding of vocal communication of emotion. However, in contrast to studies of animal vocalizations, this research has focused mainly on the emotional interpretation of such signals. The repertoire of human nonverbal vocalizations as acoustic types, and the mapping between acoustic and emotional categories, thus remain underexplored. In a cross-linguistic naming task (Experiment 1), verbal categorization of 132 authentic (non-acted) human vocalizations by English-, Swedish- and Russian-speaking participants revealed the same major acoustic types: laugh, cry, scream, moan, and possibly roar and sigh. The association between call type and perceived emotion was systematic but non-redundant: listeners associated every call type with a limited, but in some cases relatively wide, range of emotions. The speed and consistency of naming the call type predicted the speed and consistency of inferring the caller’s emotion, suggesting that acoustic and emotional categorizations are closely related. However, participants preferred to name the call type before naming the emotion. Furthermore, nonverbal categorization of the same stimuli in a triad classification task (Experiment 2) was more compatible with classification by call type than by emotion, indicating the former’s greater perceptual salience. These results suggest that acoustic categorization may precede attribution of emotion, highlighting the need to distinguish between the overt form of nonverbal signals and their interpretation by the perceiver. Both within- and between-call acoustic variation can then be modeled explicitly, bringing research on human nonverbal vocalizations more in line with the work on animal communication.
