Crying does not alleviate acute pain perception: Evidence from an experimental study.

BACKGROUND: Whereas previous studies revealed positive effects of emotional expressions such as swearing and laughing on acute pain, systematic research on the effects of crying on pain is missing. The rationale for the current study is that either a mere emotional distraction or changes in oxytocin and opioid levels represent a mechanism through which crying modulates pain, with the timing of mood changes as crucial information for distinguishing between potential mechanisms. METHODS: In two studies, we exposed participants (Study 1: n = 57; Study 2: n = 70) to a sad movie and measured their mood, and exposed them to pain induction procedures (electric shock and cold-pressor test, respectively) before and after the film. Dependent variables were pain threshold, tolerance, and intensity. In addition to baseline and one immediate post-crying mood and pain response measurement in both studies, in Study 2, we repeated these procedures 20 and 50 min later to discern between the potential role of neurobiological substances and distraction. RESULTS: Crying was elicited in 28 participants in Study 1 (49.1%) and 49 (70%) in Study 2. We found no systematic differences in pain and mood changes between criers and non-criers and no systematic dose-response relationship between crying and pain responses and mood. The only significant effects ran contrary to our hypotheses, showing detrimental effects of the occurrence (Study 1) and frequency of crying (both studies) on pain threshold. CONCLUSIONS: Results do not support the idea that crying has pain-alleviating effects, either via distraction or direct biological mechanisms. SIGNIFICANCE: Despite previous findings on pain alleviating effects of emotional expression and the widespread idea about the generally beneficial consequences of emotional crying, research on the possible pain alleviating effects of crying is largely missing. Two quasi-experimental studies demonstrated that crying induced in laboratory conditions does not alleviate acute pain responses, suggesting that role of crying in pain interventions is doubtful. Less directly, results cast light on the role of emotional distraction from acute pain and possible crying-related neurochemical changes.

A clinical practice review of crying research.

The goal of this clinical practice review is to assess the current state of the theoretical and empirical literature on emotional crying (i.e., crying in response to an emotional stimulus), a topic that has received surprisingly limited attention of behavioral scientists and clinicians. Although the empirical research on emotional crying remains in a nascent state, we draw upon the existing scientific knowledge to provide preliminary suggestions for clinicians on how to interpret and respond to crying in clinical contexts. We also identify research gaps and provide recommendations for further research to improve our understanding of this intriguing and still poorly understood human behavior. We suggest that a better understanding of individual differences in crying behavior and the postulated intraindividual and interindividual functions of crying is of critical importance for clinicians, given its frequent occurrence and notable associations with emotional and social functioning. An improved characterization of this important phenomenon will lead to improvements in clinical assessment, treatment planning, and psychotherapy interventions.

The Croatian version of the Emotion Regulation Questionnaire: Links with higher- and lower-level personality traits and mood.

The Emotion Regulation Questionnaire (ERQ) measures habitual use of two emotion regulation strategies, cognitive reappraisal and expressive suppression. The present study tested the psychometric properties and validity of a newly developed Croatian adaptation of the ERQ. In a sample of 347 participants, we first sought to confirm the ERQ's original factor structure. Next, we tested its convergent, divergent and incremental validity. In the first subsample (N = 140), we linked the ERQ with a measure of the Five-Factor Model dimensions and their facets (Revised NEO Personality Inventory). In the second subsample (N = 207), we tested its ability to predict personality dimensions assessed by a different measure (Big Five Inventory) as well as the traits of positive and negative affect, including its incremental validity in predicting the latter. The results corroborated earlier findings, showing that the Croatian ERQ has equivalent psychometrics and predictive validity as ERQs in other languages. Crucially, the observed links between the ERQ and the facets of the Five-Factor Model dimensions enrich our understanding of the personality mechanisms behind the employment of these emotion regulation strategies.

The Relationship of Gender Roles and Beliefs to Crying in an International Sample.

This study aimed to (1) investigate the variation in self ascription to gender roles and attitudes toward gender roles across countries and its associations with crying behaviors, emotion change, and beliefs about crying and (2) understand how the presence of others affects our evaluations of emotion following crying. This was a large international survey design study (N = 893) conducted in Australia, Croatia, the Netherlands, Thailand, and the United Kingdom. Analyses revealed that, across countries, gender, self-ascribed gender roles, and gender role attitudes (GRA) were related to behavioral crying responses, but not related to emotion change following crying. How a person evaluates crying, instead, appeared to be highly related to one's beliefs about the helpfulness of crying, irrespective of gender. Results regarding crying when others were present showed that people are more likely both to cry and to feel that they received help around a person that they know, compared to a stranger. Furthermore, closeness to persons present during crying did not affect whether help was provided. When a crier reported that they were helped, they also tended to report feeling better following crying than those who cried around others but did not receive help. Few cross-country differences emerged, suggesting that a person's responses to crying are quite consistent among the countries investigated here, with regard to its relationship with a person's gender role, crying beliefs, and reactions to the presence of others.

The neurobiology of human crying.

The production of emotional tears appears to be uniquely present in Homo sapiens. Despite the ubiquity of this human behavior, research is only just beginning to uncover the neurobiologic underpinnings of human emotional crying. In this article, we review the current state of the literature investigating the neurobiologic aspects of this uniquely human behavior, including the neuroanatomical, neurochemical, and psychophysiologic findings. To set the context for this review, we first provide a brief overview of the evolutionary background and functions of tearful crying. Despite an accumulating understanding of the neurobiology of human emotional crying, the primary sources of information are currently from animal studies and observations in neurologic patients suffering from pathologic crying. Currently, most of the research on the neurobiology of crying in humans has focused on autonomic physiologic processes underlying tearful crying, which may yield essential clues regarding the neural substrates of the production of crying behavior and its effects on the crier. Further challenges in elucidating the neurobiology of crying involve the complexity of crying behavior, which includes vocalizations, tear production, the involvement of facial musculature, subjective emotional experience, emotion regulatory behaviors, and social behaviors. Future research is needed to comprehensively characterize the neurobiology of this intriguing and complex human behavior.

Kama muta: Conceptualizing and measuring the experience often labelled being moved across 19 nations and 15 languages.

English-speakers sometimes say that they feel "moved to tears," "emotionally touched," "stirred," or that something "warmed their heart;" other languages use similar passive contact metaphors to refer to an affective state. The authors propose and measure the concept of kama muta to understand experiences often given these and other labels. Do the same experiences evoke the same kama muta emotion across nations and languages? They conducted studies in 19 different countries, 5 continents, 15 languages, with a total of 3,542 participants. They tested the construct while validating a comprehensive scale to measure the appraisals, valence, bodily sensations, motivation, and lexical labels posited to characterize kama muta. The results are congruent with theory and previous findings showing that kama muta is a distinct positive social relational emotion that is evoked by experiencing or observing a sudden intensification of communal sharing. It is commonly accompanied by a warm feeling in the chest, moist eyes or tears, chills or piloerection, feeling choked up or having a lump in the throat, buoyancy, and exhilaration. It motivates affective devotion and moral commitment to communal sharing. Although the authors observed some variations across cultures, these 5 facets of kama muta are highly correlated in every sample, supporting the validity of the construct and the measure.

The Effects of Tears on Approach-Avoidance Tendencies in Observers.

Emotional tears have been proposed to represent a robust affiliative signal whose main function is to promote the willingness to help the crying individual. However, little is known about the psychological mechanisms at the basis of such responses. To investigate whether tears facilitate approach relative to avoidance tendencies, we exposed participants ( N = 77) to pictures of faces with and without visible tears, in two different approach-avoidance tasks. In the first task, participants were instructed to either move toward tearful faces and away from nontearful faces, or the other way around, by using a joystick. In the second task, participants made approaching or avoiding responses to tearful and nontearful faces by pressing buttons. The results suggest that tears facilitate behavior that reduces the distance between the observer and the crying person. However, while tears appear to promote approach relative to avoidance behavior, the current findings do not allow firm conclusions about whether tears specifically facilitate approach or rather block avoidance tendencies in observers, or whether they possibly have both effects. Findings are discussed in the context of tears' ability to act as a prosocial stimulus that signals non-aggressive intentions, as well as in the context of the functional goals that predispose humans to approach or avoid crying individuals.

Why Only Humans Shed Emotional Tears : Evolutionary and Cultural Perspectives.

Producing emotional tears is a universal and uniquely human behavior. Until recently, tears have received little serious attention from scientists. Here, we summarize recent theoretical developments and research findings. The evolutionary approach offers a solid ground for the analysis of the functions of tears. This is especially the case for infant crying, which we address in the first part of this contribution. We further elaborate on the antecedents and (intra- and interpersonal) functions of emotional tears in adults. The main hypothesis that emerges from this overview is that crying evolved as an emotional expression that signals distress and promotes prosocial behaviors in conspecifics. Further, shedding tears may influence the mood of the crier and his/her outlook on life primarily as a consequence of fulfillment of the proposed signaling function of tears. We also describe how cultural phenomena such as ritual weeping nicely fit within this framework, as they often aim to support a request for help to a powerful person or deity and promote social bonding.

Chemosignalling effects of human tears revisited: Does exposure to female tears decrease males' perception of female sexual attractiveness?

Gelstein et al. reported the results of three experiments suggesting a dampening influence of inhalation of female emotional tears on males' arousal and perception of female sexual attractiveness, specifically in non-sexual situations. This prompted the hypothesis that crying exerts its influence on others not only via the auditory and visual mode but also via chemosignals. In three studies, we attempted to replicate and extend Gelstein et al.'s findings by including an additional condition with irritant tears, by using pictures of sexually attractive women, and by testing related hypotheses on the pro-social effects of exposure to tears. All three studies, separately or combined in a meta-analysis, failed to replicate the original inhibitory effects of tears. In addition, sniffing tears did not affect measures of connectedness, aggression and pro-social behaviour. It is concluded that the effects of female tears on male arousal and perception of female sexual attractiveness, if any, are very weak at best. Rather, it seems that crying exerts its strong inter-personal effects through the visual and auditory sensory channels.

Why crying does and sometimes does not seem to alleviate mood: a quasi-experimental study.

Whereas retrospective studies suggest that crying can be beneficial in terms of mood enhancement, results of quasi-experimental laboratory studies consistently demonstrate its negative effects on mood. The present study was specifically designed to evaluate a parsimonious explanation for this paradox by assessing mood after crying in a laboratory, both immediately and at follow up. Mood ratings of 28 objectively established criers and 32 non-criers were compared before and immediately after the exposure to an emotional movie, as well as 20 and 90 min later. As expected, immediately after the film, negative mood significantly increased in criers, while it did not change in non-criers. This mood deterioration was followed by a recovery that resulted in return to the baseline mood levels at the third measurement. Criers subsequently reported mood enhancements at the final measurement compared to the pre-film measurement. Crying frequency did not predict mood changes above those predicted by the presence of crying. The observed relation between crying and more long-term mood recovery reconciles seemingly contrasting earlier results and provides a simple and obvious explanation. After the initial deterioration of mood following crying that was observed in laboratory studies, it apparently takes some time for the mood, not just to recover, but also to become even less negative than before the emotional event, which corresponds to the results of retrospective studies.

Is crying a self-soothing behavior?

This contribution describes the current state-of-the-art of the scientific literature regarding the self-soothing effects of crying. Starting from the general hypothesis that crying is a self-soothing behavior, we consider different mechanisms through which these effects may appear. In the first section, we briefly explain the main functions of human crying. Then we define self-soothing in terms of homeostatic processes of mood regulation and stress reduction and we underline the importance of distinguishing self-soothing effects of crying from social-soothing that it may elicit. We then provide a comprehensive review of the putative mood-enhancing and -relieving effects of crying and their variations stemming from characteristics of crying person, antecedents, manifestations, and social consequences of crying. We also discuss the possible methodological explanations for the seemingly discrepant findings regarding mood improvement and relief that may follow crying. We then provide theoretical and empirical support for our general hypothesis that crying is a self-soothing behavior by presenting and evaluating the possible physiological, cognitive, and behavioral mechanisms that may play a mediating role in the relationship between crying and homeostatic regulation that includes mood improvement and relief. Starting from the idea that social-soothing and self-soothing mechanisms share the same physiological systems, we propose that biological processes act in parallel with learning and reappraisal processes that accompany crying, which results in homeostatic regulation. Given the parallels between self-soothing behaviors in humans and animals, we also propose that crying might self-soothe through a mechanism that shares key properties with rhythmical, stereotypic behaviors. We conclude that, in addition to the importance of socially mediated mechanisms for the mood-enhancing effects of crying, there is converging evidence for the direct, self-soothing effects of crying.
