Creating Expressive Social Robots That Convey Symbolic and Spontaneous Communication.

Robots are becoming an increasingly important part of our society and have started to be used in tasks that require communicating with humans. Communication can be decoupled in two dimensions: symbolic (information aimed to achieve a particular goal) and spontaneous (displaying the speaker's emotional and motivational state) communication. Thus, to enhance human-robot interactions, the expressions that are used have to convey both dimensions. This paper presents a method for modelling a robot's expressiveness as a combination of these two dimensions, where each of them can be generated independently. This is the first contribution of our work. The second contribution is the development of an expressiveness architecture that uses predefined multimodal expressions to convey the symbolic dimension and integrates a series of modulation strategies for conveying the robot's mood and emotions. In order to validate the performance of the proposed architecture, the last contribution is a series of experiments that aim to study the effect that the addition of the spontaneous dimension of communication and its fusion with the symbolic dimension has on how people perceive a social robot. Our results show that the modulation strategies improve the users' perception and can convey a recognizable affective state.

Family Emotional Expressiveness and Adolescents' Cyberbullying Bystanders: The Mediating Role of Empathy.

Background: The significant influence of family emotional expressiveness (FEE) on adolescents' face-to-face social interactions is well-established. However, there has been limited investigation into potential links between FEE and adolescents' online social behaviors, especially cyberbullying bystander behaviors, which are pivotal in cyberbullying incidents. This study aimed to assess the relative importance of different aspects of FEE (positive FEE vs. negative FEE vs. the Positive-to-Negative ratio) in predicting adolescents' cyberbullying bystander behaviors, and the mediating roles of affective and cognitive empathy in these relationships. Methods: A sample of 1,952 adolescents (Mage = 14.18, SD = 1.33) completed questionnaires, including the Family Emotional Expressiveness Questionnaire, Basic Empathy Scale, and Cyberbullying Bystander Behavior Scale. SPSS 26.0 and Mplus 8.3 were used for analysis. Results: (1) Positive FEE exhibited a positive association with protective behavior and a negative association with indifferent behavior. Conversely, negative FEE showed positive associations with reinforcing and indifferent behaviors. However, the Positive-to-Negative ratio did not exhibit significant associations with any of the three bystander behaviors. (2) Negative FEE emerged as relatively more significant than both positive FEE and the Positive-to-Negative ratio in predicting reinforcing and indifferent behaviors. (3) Affective empathy mediated the relationship between positive FEE and reinforcing behavior, while cognitive empathy mediated the relationship between positive FEE and protective and indifferent behaviors. Moreover, cognitive empathy exerted a more influential role than affective empathy in this mediation process. Conclusion: Various aspects of FEE demonstrated distinct relationships with three cyberbullying bystander behaviors, with affective and cognitive empathy playing an important mediating role in the association. This finding holds substantial implications for the development of cyberbullying prevention strategies. Such strategies could target the reduction of negative emotional expression within adolescent families and the cultivation of both cognitive and affective empathy.

Testing the temporal precedence of family functioning and child psychopathology in the LONGSCAN sample.

Family functioning may serve as protective or risk factors in the development of youth psychopathology. However, few studies have examined the potentially reciprocal relation between child psychopathology and family functioning. To fill this gap in the literature, this study tested for time-ordered associations between measures of family functioning (e.g., cohesion, conflict, and emotional expressiveness) and child psychopathology (e.g., total behavior problems, externalizing, and internalizing problems) using data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN; N = 1143, 52.3% female, Nwaves = 5). We used a random-intercept cross-lagged panel model to identify whether child psychopathology preceded and predicted family functioning, the reverse, or both processes occurred simultaneously. At the between-person level, families who tended to have more cohesion, who lacked conflict, and who expressed their emotions had lower levels of child psychopathology. At the within-person level in childhood, we found minimal evidence for time-ordered associations. In adolescence, however, a clear pattern whereby early psychopathology consistently predicted subsequent family functioning emerged, and the reverse direction was rarely found. Results indicate a complex dynamic relation between the family unit and child that have important implications for developmental models that contextualize risk and resilience within the family unit.

Gene Self-Expressive Networks as a Generalization-Aware Tool to Model Gene Regulatory Networks.

Self-expressiveness is a mathematical property that aims at characterizing the relationship between instances in a dataset. This property has been applied widely and successfully in computer-vision tasks, time-series analysis, and to infer underlying network structures in domains including protein signaling interactions and social-networks activity. Nevertheless, despite its potential, self-expressiveness has not been explicitly used to infer gene networks. In this article, we present Generalizable Gene Self-Expressive Networks, a new, interpretable, and generalization-aware formalism to model gene networks, and we propose two methods: GXN•EN and GXN•OMP, based respectively on ElasticNet and OMP (Orthogonal Matching Pursuit), to infer and assess Generalizable Gene Self-Expressive Networks. We evaluate these methods on four Microarray datasets from the DREAM5 benchmark, using both internal and external metrics. The results obtained by both methods are comparable to those obtained by state-of-the-art tools, but are fast to train and exhibit high levels of sparsity, which make them easier to interpret. Moreover we applied these methods to three complex datasets containing RNA-seq informations from different mammalian tissues/cell-types. Lastly, we applied our methodology to compare a normal vs. a disease condition (Alzheimer), which allowed us to detect differential expression of genes' sub-networks between these two biological conditions. Globally, the gene networks obtained exhibit a sparse and modular structure, with inner communities of genes presenting statistically significant over/under-expression on specific cell types, as well as significant enrichment for some anatomical GO terms, suggesting that such communities may also drive important functional roles.

Intergenerational effects of childhood maltreatment: The relationships among parental childhood emotional neglect, emotional expressiveness and children's problem behaviors.

BACKGROUND: Childhood maltreatment has a severe impact on both the health and parenting styles of abused individuals in adulthood, and it even has a negative impact on the offspring of abused individuals. Although studies have confirmed the intergenerational effects of childhood maltreatment, relatively few have emphasized emotional neglect and its mechanism of intergenerational effects. Additionally, few studies have examined the unique role of fathers and how mothers and fathers interact with one another. OBJECTIVE: The current study aimed to employ the actor-partner interdependence mediation model to investigate the relationship between parental childhood emotional neglect and children's problem behaviors, as well as whether parents' positive and negative emotional expressiveness plays a mediating role. METHODS, PARTICIPANTS, AND SETTING: In total, 397 dyads of mothers and fathers of children aged 6-9 were recruited and reported their childhood emotional neglect experience and emotional expressiveness, and mothers also rated their children's problem behaviors. RESULTS: The findings revealed that (a) maternal childhood emotional neglect was associated solely with mothers' own negative emotional expressiveness, followed by their children's problem behavior and (b) paternal childhood emotional neglect showed no effect on children's problem behavior through fathers' own or their spouses' positive and negative emotional expressiveness. CONCLUSIONS: The findings of this study suggest that childhood emotional neglect has intergenerational effects and that mothers' parenting behaviors are relatively important in preventing adverse effects on their children.

Análise da Viabilidade de Uso do FNIRS em Atividades Educacionais com Crianças e Jovens com Deficiência Intelectual e Autismo / Analysis of FNIRS Usability in Educational Activities with Children and Young People with Intellectual Disability and Autism

RESUMO: Métodos em neurociência cognitiva podem auxiliar o planejamento educacional de docentes no contexto da Educação Especial, por favorecerem práticas personalizadas que valorizem a velocidade individual de aprendizagem de estudantes com transtorno do espectro do autismo (TEA) e/ou deficiência intelectual (DI). Assim sendo, este estudo objetivou verificar a viabilidade de uso da Espectroscopia Funcional de Infravermelho Próximo (fNIRS) em situação naturalística clínica com crianças e jovens com TEA e/ou DI durante tarefas de ensino. Ademais, o estudo buscou identificar as estratégias de treino para que as crianças e os jovens utilizassem o equipamento durante a realização da atividade. Sete estudantes com diagnóstico de TEA e/ou DI foram treinados com atividades de matemática, leitura e expressividade emocional, de acordo com seus respectivos currículos educacionais prévios. Cada participante foi exposto a duas tarefas em cada atividade, uma na qual já apresentava domínio e outra que necessitava de apoio para emitir uma resposta independente. Os resultados indicaram a viabilidade de uso do fNIRS nesse contexto natural da criança e do jovem e forneceram medidas implícitas para além das medidas observacionais de acerto e erro na tarefa. Esta é uma importante demonstração da viabilidade do uso do fNIRS em experimentos no contexto da Educação Especial.

ABSTRACT: Methods in cognitive neuroscience can assist educational planning of teachers in the context of Special Education, as they favor personalized practices that value individual students with Autism Spectrum Disorder (ASD) and/or Intellectual Deficiency (ID). Therefore, this study aimed to verify the feasibility of using functional near-infrared spectroscopy (fNIRS) in clinical naturalistic situation with children and young people with ASD and/or ID during teaching tasks. In addition, the study sought to identify training strategies so that children and young people use the equipment during the activity. Seven students diagnosed with ASD and/or ID were trained with mathematics, reading and emotional expressiveness, according to their respective previous educational curricula. Each participant was exposed to two tasks in each activity, one in which he/she already had a domain and one that needed support to issue an independent response. The results indicated the feasibility of using fNIRS in this natural context of the child and the young student and provided implicit measures beyond the observational arrangement measures and task error. This is an important demonstration of the feasibility of using fNIRS in experiments in the context of Special Education.

Instructors' expressive nonverbal behavior hinders learning when learners' prior knowledge is low.

This study investigated the influence of instructors' expressive nonverbal behavior and nonexpressive nonverbal behavior in video lectures on students' learning performance and affective experience. We conducted two rounds of experiments using the same materials and procedures, the only difference being the participants. In each round of experiments, participants were randomly assigned to expressive condition or nonexpressive condition. 227 rural primary school sixth-graders took part in experiment 1, participants in expressive condition had better affective experiences and perceived tasks as less difficult, but had lower learning performance than participants in nonexpressive condition. 175 sixth-graders from urban primary schools participated in experiment 2. The results showed that instructors' expressive nonverbal behavior also improved students' affective experience and reduced students' perception of task difficulty, but there was no significant difference in learning performance between the two groups. Comparing the pretest scores of students in the two experiments, it was found that the pretest scores of participants in experiment 2 were higher than those in experiment 1. Overall, instructors' expressive nonverbal behavior can improve students' affective experience and reduce their perception of task difficulty. However, when students' prior knowledge is relatively low, instructors' expressive nonverbal behavior hinders students' learning performance. We suggest that teachers adopt expressive nonverbal behavior when lecturing because it is beneficial to maintain students' long-term interest in learning. However, it should be noted that the difficulty of learning material should be determined by students' prior knowledge.

Cultivation and interpretation of students' psychological quality: Vocal psychological model.

Reflecting students' mental health data through vocal music teaching expressive system is a research hotspot in vocal music teaching psychology. Based on the theory of students' expressiveness in vocal music teaching, this paper constructs a psychological model of vocal music teaching. The model uses psychological data mining technology to conduct a feasibility study and analysis on the mental health education of vocal music students, solves the quantitative problem of mental health, and analyzes the relationship between psychological problems and students. In the simulation process, the psychological data of the vocal music freshmen of a certain college was taken as the research object, and the association rule Apriori algorithm was used to analyze the relationship between the factors of the psychological dimension. Psychological data mining was carried out, and descriptive indicators and univariate analysis methods were used to analyze the current situation of students' mental health and personality characteristics, and Pearson correlation analysis and structural equation model were used to explore the relationship between their mental health and personality characteristics. The amount of vocal music learning is the duration of the load and the total number of tasks completed within a single exercise or a series of exercises. ASP-NET and SQLServer2008 and other experimental results show that the chi-square test value of the overall fit of the model is 20.078, and the ratio of the chi-square value to the degree of freedom is 4.016, which has a relatively high accuracy and effectively enhances the psychological data mining technology in vocal music students for operation and practicality of applications in health data analysis.

Diurnal Cortisol in Left-Behind Adolescents: Relations to Negative Family Expressiveness and Internalizing Problems.

Despite the accumulating evidence for increased risks for behavioral problems in left-behind adolescents in China, little research has explored their HPA axis functioning, which is hypothesized to play a central role in the association between early adversity and health. In the present study, we designed a longitudinal study to examine HPA axis function in left-behind adolescents and its mediating role in the association between family emotional expressiveness and internalizing problems. Participants were 81 adolescents (44 female; 37 male) aged 11-16 years. Salivary cortisol samples were collected six times a day for two consecutive days on regular school days. Negative family expressiveness (NFE) and internalizing problems were measured using self-report questionnaires. The results showed that NFE was negatively associated with diurnal cortisol, and diurnal cortisol was negatively associated with internalizing problems. Further analysis showed that diurnal cortisol secretion measured by AUC (area under the curve) mediated the association between NFE and internalizing problems. Our findings extended the existing literature about left-behind children via a psychoneuroendocrinological perspective, documenting the negative consequences of the family environment for youth health and development.

Emotion Recognizing by a Robotic Solution Initiative (EMOTIVE Project).

BACKGROUND: Emotion recognition skills are predicted to be fundamental features in social robots. Since facial detection and recognition algorithms are compute-intensive operations, it needs to identify methods that can parallelize the algorithmic operations for large-scale information exchange in real time. The study aims were to identify if traditional machine learning algorithms could be used to assess every user emotions separately, to relate emotion recognizing in two robotic modalities: static or motion robot, and to evaluate the acceptability and usability of assistive robot from an end-user point of view. METHODS: Twenty-seven hospital employees (M = 12; F = 15) were recruited to perform the experiment showing 60 positive, negative, or neutral images selected in the International Affective Picture System (IAPS) database. The experiment was performed with the Pepper robot. Concerning experimental phase with Pepper in active mode, a concordant mimicry was programmed based on types of images (positive, negative, and neutral). During the experimentation, the images were shown by a tablet on robot chest and a web interface lasting 7 s for each slide. For each image, the participants were asked to perform a subjective assessment of the perceived emotional experience using the Self-Assessment Manikin (SAM). After participants used robotic solution, Almere model questionnaire (AMQ) and system usability scale (SUS) were administered to assess acceptability, usability, and functionality of robotic solution. Analysis wasperformed on video recordings. The evaluation of three types of attitude (positive, negative, andneutral) wasperformed through two classification algorithms of machine learning: k-nearest neighbors (KNN) and random forest (RF). RESULTS: According to the analysis of emotions performed on the recorded videos, RF algorithm performance wasbetter in terms of accuracy (mean ± sd = 0.98 ± 0.01) and execution time (mean ± sd = 5.73 ± 0.86 s) than KNN algorithm. By RF algorithm, all neutral, positive and negative attitudes had an equal and high precision (mean = 0.98) and F-measure (mean = 0.98). Most of the participants confirmed a high level of usability and acceptability of the robotic solution. CONCLUSIONS: RF algorithm performance was better in terms of accuracy and execution time than KNN algorithm. The robot was not a disturbing factor in the arousal of emotions.

Narrativas na carne: as tatuagens dos jovens na socioeducação / Narratives in the flesh: the tattoos of young people in socio-education / Narrativas en la carne: los tatuajes de los jóvenes en la socioeducación

Este artigo objetiva analisar as expressões psíquicas, identitárias e sociais das tatuagens de jovens em cumprimento de medida socioeducativa de internação, compreendendo que seus corpos são territórios de simbologia, memórias, afetos e filiações. Trata-se de uma pesquisa clínico-qualitativa a partir da imersão no campo e dos registros etnográficos. Partindo dos relatos de campo, construímos eixos narrativos das tatuagens que estiveram constantemente nas peles dos jovens, como o nome da mãe, as homenagens aos parentes mortos, o nome próprio e os marcadores religiosos, entendendo-os a partir das ligações com o âmbito social, institucional e territorial. Assim, as tatuagens desses jovens são repletas de significações e dizem de um mundo interno que tenta se apresentar, demarcar lugares e sair da invisibilidade.

This article aims to analyze the psychic, identity and social expressions of the tattoos of young people in compliance with a socio-educational measure of deprived liberty, understanding that their bodies are territories of symbolism, memories, affections and affiliations. This is a clinical-qualitative research based on immersion in the field and ethnographic records. Based on field reports, we built narrative axes of tattoos that were constantly on the skins of young people, such as the name of the mother, homage to dead, proper names, religious symbols, understanding them based on the connections with the social, institutional, and territorial area. Thus, the tattoos of these young people are full of meanings and tell of an internal world that tries to present itself, demarcate places and come out from invisibility.

Este artículo tiene como objetivo analizar las expresiones psíquicas, identitarias y sociales de los tatuajes de los jóvenes en cumplimiento de una medida socioeducativa de internación, entendiendo que sus cuerpos son territorios de simbolismo, recuerdos, afectos y afiliaciones. Se trata de una investigación clínico-cualitativa basada en la inmersión en el campo y los registros etnográficos. A partir de informes de campo, construimos ejes narrativos de tatuajes que estaban constantemente en la piel de los jóvenes, como el nombre de la madre, homenaje a familiares fallecidos, nombres propios, símbolos religiosos, entendiéndolos desde las conexiones con el ámbito social, institucional y territorial. Así, los tatuajes de estos jóvenes están llenos de significados y hablan de un mundo interno que intenta presentarse, demarcar lugares y dejar la invisibilidad.

Effects of Emotional Expressiveness of a Female Digital Human on Loneliness, Stress, Perceived Support, and Closeness Across Genders: Randomized Controlled Trial.

BACKGROUND: Loneliness is a growing public health problem that has been exacerbated in vulnerable groups during the COVID-19 pandemic. Social support interventions have been shown to reduce loneliness, including when delivered through technology. Digital humans are a new type of computer agent that show promise as supportive peers in health care. For digital humans to be effective and engaging support persons, it is important that they develop closeness with people. Closeness can be increased by emotional expressiveness, particularly in female relationships. However, it is unknown whether emotional expressiveness improves relationships with digital humans and affects physiological responses. OBJECTIVE: The aim of this study is to investigate whether emotional expression by a digital human can affect psychological and physiological outcomes and whether the effects are moderated by the user's gender. METHODS: A community sample of 198 adults (101 women, 95 men, and 2 gender-diverse individuals) was block-randomized by gender to complete a 15-minute self-disclosure conversation with a female digital human in 1 of 6 conditions. In these conditions, the digital human varied in modality richness and emotional expression on the face and in the voice (emotional, neutral, or no face; emotional or neutral voice). Perceived loneliness, closeness, social support, caring perceptions, and stress were measured after each interaction. Heart rate, skin temperature, and electrodermal activity were assessed during each interaction. 3-way factorial analyses of variance with post hoc tests were conducted. RESULTS: Emotional expression in the voice was associated with greater perceptions of caring and physiological arousal during the interaction, and unexpectedly, with lower feelings of support. User gender moderated the effect of emotional expressiveness on several outcomes. For women, an emotional voice was associated with increased closeness, social support, and caring perceptions, whereas for men, a neutral voice increased these outcomes. For women, interacting with a neutral face was associated with lower loneliness and subjective stress compared with no face. Interacting with no face (ie, a voice-only black screen) resulted in lower loneliness and subjective stress for men, compared with a neutral or emotional face. No significant results were found for heart rate or skin temperature. However, average electrodermal activity was significantly higher for men while interacting with an emotional voice. CONCLUSIONS: Emotional expressiveness in a female digital human has different effects on loneliness, social, and physiological outcomes for men and women. The results inform the design of digital human support persons and have theoretical implications. Further research is needed to evaluate how more pronounced emotional facial expressions in a digital human might affect the results.

GaborNet Visual Encoding: A Lightweight Region-Based Visual Encoding Model With Good Expressiveness and Biological Interpretability.

Computational visual encoding models play a key role in understanding the stimulus-response characteristics of neuronal populations in the brain visual cortex. However, building such models typically faces challenges in the effective construction of non-linear feature spaces to fit the neuronal responses. In this work, we propose the GaborNet visual encoding (GaborNet-VE) model, a novel end-to-end encoding model for the visual ventral stream. This model comprises a Gabor convolutional layer, two regular convolutional layers, and a fully connected layer. The key design principle for the GaborNet-VE model is to replace regular convolutional kernels in the first convolutional layer with Gabor kernels with learnable parameters. One GaborNet-VE model efficiently and simultaneously encodes all voxels in one region of interest of functional magnetic resonance imaging data. The experimental results show that the proposed model achieves state-of-the-art prediction performance for the primary visual cortex. Moreover, the visualizations demonstrate the regularity of the region of interest fitting to the visual features and the estimated receptive fields. These results suggest that the lightweight region-based GaborNet-VE model based on combining handcrafted and deep learning features exhibits good expressiveness and biological interpretability.

Primary caregiver emotional expressiveness relates to toddler emotion understanding.

The present study examined the impact of emotional expressiveness in toddlers' environments on their emotion understanding. Primary caregivers of 35 toddlers completed two surveys regarding the family's emotional expressiveness and the primary caregiver's expressivity. Toddlers participated in the Affective Knowledge Test to measure emotion understanding. Toddler emotion understanding related to primary caregiver expressivity, but not family expressiveness. Further, toddler emotion understanding related to primary caregiver Impulse Strength, but not Negative or Positive Emotionality. This suggests that primary caregivers with more impulsive emotional response tendencies may help their children to identify associations between emotional events and reactions.

Social Anxiety and Perceived Social Support: Gender Differences and the Mediating Role of Communication Styles.

Social anxiety has been linked with lower perceived social support, and there is some evidence that communication styles may explain this relationship. In addition, a body of literature has found gender differences in social anxiety, communication, and perceived social support. The purpose of this exploratory study was to investigate six communication styles as mediators of the relationship between social anxiety and perceived social support and whether such relationships vary by gender. College men and women (N = 813) completed an online survey. Among men and women, social anxiety was associated with lower social support through lower expressiveness. Among men, social anxiety was associated with lower perceived social support through lower preciseness; among women, this link was through lower verbal aggressiveness and higher emotionality. Psychotherapy may function as an environment in which socially anxious individuals can learn communication skills and acquire the confidence to use them in order to increase perceived social support.

Psychometric Properties and a Preliminary Validation Study of the Italian Brief Version of the Communication Styles Inventory (CSI-B/I).

People will typically develop a communication style that tends to be coherent with their own fundamental personality traits. The current debate on communication style acknowledges the construct of adaptive behavior as an appropriate area where to include both the strictly personal aspects and social learning and cultural assimilation, which translate into communicative style as a specific form of adaptation integrating the behavioral and personality perspectives. Due to the lack of instruments in the Italian psychometric scenario to assess communication styles, the present study included the translation and validation of the Italian short version of the Communication Styles Inventory (CSI-B/I). METHODS: The CSI-B/I was administered to a sample of 1,044 participants, while the concurrent validity was tested through a second administration to 518 participants along with the MPP (Multidimensional Personality Profile). RESULTS: Confirmatory factor analysis bore out a three-factor solution (including 18 items) with good indices of adaptation to data, e.g., χ2/df = 1.251, RMSEA = 0.027, RMSEA 90% CI = 0.008-0.040, GFI = 0.958, AGFI = 0.937, CFI = 0.983 and NFI = 0.922. The CSI-B/I allows to measure three main dimensions of the communication style: impression manipulativeness; emotionality; expressiveness. Internal consistency reliability and significant correlations with the MPP supported the concurrent validity of the tool. CONCLUSION: By virtue of its good psychometric properties, CSI-B/I represents an important addition to the assessment in multiple contexts: companies, institutions, staff selection, individual and group profile analysis, coaching, psychotherapy, counseling, career guidance.

Effects of journal therapy counseling with anxious pregnant women on their infants' sleep quality: a randomized controlled clinical trial.

BACKGROUND: Sleep is especially important for infants, since it stimulates the development of neural connections in their brains. Psychological stress such as anxiety could affect sleep quality. This study investigated the effects of journal therapy counseling sessions on the infants' sleep quality based on mothers' perception (primary outcome), maternal anxiety, infants' anthropometric and developmental parameters, and the frequency of exclusive breastfeeding (secondary outcomes). METHODS: A total of 70 healthy women with gestational age of 28-31 weeks participated in this randomized controlled trial. The participants were randomly allocated into intervention and control groups using randomized block design. Three in-person journal therapy sessions and three telephone counseling sessions (2 between in-person sessions and 1 one month postpartum) were provided to those in the intervention group, while the control group only received routine care. The Infant Sleep Questionnaire (ISQ), Exclusive Breastfeeding Checklist, and Infant Anthropometric Parameters Checklist were completed at two and four months postpartum. The Beck Anxiety Inventory (BAI) was completed during pregnancy, at the end of the intervention, and at two and four months postpartum, and the Ages and Stages Questionnaire (ASQ) was completed at 4 months postpartum. Data were analyzed using chi-square, independent t-test, ANCOVA and repeated measure ANOVA. RESULTS: There was no significant difference between the two groups in demographic characteristics and baseline anxiety scores. The mean sleep quality score in infants two months of age (MD: -4.2; 95%CI: - 1.1 to - 7.2; P = 0.007) and four months of age (MD: -5.5; 95%CI: - 8.4 to - 2.7; P < 0.001) was significantly lower in the intervention group than that of those in the control group. Based on the repeated measure ANOVA results, the mean postpartum anxiety score of mothers in the intervention group was significantly lower than that of those in the control group (AMD: -7.7; 95%CI: - 5.5 to - 10.1; P < 0.001). There was no significant difference between the two groups regarding other outcomes including the frequency of exclusive breastfeeding, and anthropometric and developmental parameters (P > 0.05). CONCLUSION: Journal therapy can decrease mothers' anxiety and improve the infants' sleep quality based on their perception. However, further studies are required before drawing any definitive conclusion. TRIAL REGISTRATION NUMBER: Iranian Registry of Clinical Trials (IRCT): IRCT20120718010324N45.

Theoretical Framework for Facilitating Young Musicians' Learning of Expressive Performance.

Since communication and expression are central aspects of music performance it is important to develop a systematic pedagogy of teaching children and teenagers expressiveness. Although research has been growing in this area a comprehensive literature review that unifies the different approaches to teaching young musicians expressiveness has been lacking. Therefore, the aim of this article is to provide an overview of literature related to teaching and learning of expressiveness from music psychology and music education research in order to build a new theoretical framework for teaching and learning expressive music performance in instrumental music lessons with children and teenagers. The article will start with a brief discussion of interpretation and expression in music performance, before providing an overview of studies that investigated teaching and learning of performance expression in instrumental music education with adults and children. On the foundation of this research a theoretical framework for dialogic teaching and learning of expressive music performance will be proposed and the rationale explained. Dialogic teaching can be useful for scaffolding young musicians' learning of expressivity as open questions can stimulate thinking about the interpretation and may serve to connect musical ideas to the embodied experience of the learner. A "toolkit" for teaching and learning of expressiveness will be presented for practical application in music lessons. In addition, a theoretical model will be proposed to further our understanding of teaching and learning of expressive music performance as a multifaceted and interactive process that is embedded in the context of tutors' and learners' experiences and environment. Finally, implications of this framework and suggestions for future research will be discussed.

Beyond Simple Differences: Moderators of Gender Differences in Heteronormativity.

Heteronormativity is a culturally embedded system defining acceptable identities and behaviors in romantic relationships. Recent literature has suggested that heteronormativity is strongly associated with political attitudes, personality characteristics such as tolerance of ambiguity, and key demographic variables such as gender and sexual orientation. However, interactions between gender and other factors have not been thoroughly explored as predictors of heteronormative attitude and beliefs. The current study (N = 306) expands the understanding of predictors of heteronormativity, particularly as they interact with gender. In the current study, higher education was associated with lower heteronormativity among women, but not among men, and expressiveness was associated with lower heteronormativity among men, but not among women. Finally, a 3-way interaction showed that the relationship between education and heteronormativity for men (but not women) depended on trait expressiveness. Future studies are recommended, including observation of changes in heteronormativity over time and exploration of mechanisms that reinforce or reduce heteronormativity.

Preconceptual Spectral and Temporal Cues as a Source of Meaning in Speech and Music.

This paper explores the importance of preconceptual meaning in speech and music, stressing the role of affective vocalizations as a common ancestral instrument in communicative interactions. Speech and music are sensory rich stimuli, both at the level of production and perception, which involve different body channels, mainly the face and the voice. However, this bimodal approach has been challenged as being too restrictive. A broader conception argues for an action-oriented embodied approach that stresses the reciprocity between multisensory processing and articulatory-motor routines. There is, however, a distinction between language and music, with the latter being largely unable to function referentially. Contrary to the centrifugal tendency of language to direct the attention of the receiver away from the text or speech proper, music is centripetal in directing the listener's attention to the auditory material itself. Sound, therefore, can be considered as the meeting point between speech and music and the question can be raised as to the shared components between the interpretation of sound in the domain of speech and music. In order to answer these questions, this paper elaborates on the following topics: (i) The relationship between speech and music with a special focus on early vocalizations in humans and non-human primates; (ii) the transition from sound to meaning in speech and music; (iii) the role of emotion and affect in early sound processing; (iv) vocalizations and nonverbal affect burst in communicative sound comprehension; and (v) the acoustic features of affective sound with a special emphasis on temporal and spectrographic cues as parts of speech prosody and musical expressiveness.
