Building a controllable expressive speech synthesis system with multiple emotion strengths

Emotion is considered to be an essential element in the performance of human-computer interactions. In expressive synthesis speech, it is important to generate emotional speech that reflects subtle and complex emotional states. However, there has been limited research on how to effectively synthesize emotional speech using different levels of emotion strength with intuitive control, which is difficult to be modeled effectively. In this paper, we explore an expressive speech synthesis model that can be used to produce speech with multiple emotion strengths. Unlike previous studies that encoded emotions into discrete codes, we propose an embedding vector to continuously control the emotion strength, which is a data-driven method to synthesize speech with a fine control over the emotions. Compared with the models using the retraining technique or a one-hot vector, our proposed model using an embedding vector can explicitly learn the high-level emotion strength from the low-level acoustic features. As a result, we can control the emotion strength of synthetic speech in a relatively predictable and globally consistent way. The objective and subjective evaluation tests show that our proposed model achieves state-of-the-art performance in terms of model flexibility and controllability.     

Effects of cognitive reappraisal and expressive suppression on daily work-related outcomes: Comparison between younger and older Chinese workers

The existing models of emotion regulation (ER) do not make any specific prediction about the differential effects of the same ER strategy among individuals of different ages. However, such assumption may not be necessarily true, given that older adults emphasise emotional goals greater than their younger counterparts. Using a daily diary approach, this study investigated whether the effects of cognitive reappraisal (CR) and expressive suppression (ES) on daily work-related outcomes would vary by age when individuals were experiencing negative events at work. A total of 141 Chinese managerial employees (M_age = 42.40, SD = 9.16) completed the diary report for 15 consecutive workdays by recording their daily work experiences. The results of the multilevel analyses showed that age moderated the effects of ES on daily negative emotions, perceived work stress, and job satisfaction. More beneficial effects were observed among older workers than among younger workers. By contrast, the use of CR significantly lowered the levels of negative emotions and perceived work stress for both younger and older workers. These findings revealed the importance of considering the role of age in evaluating the effects of ES on work-related outcomes, which provides important implications for future research and training programs in ER.     

Flexible spatial mapping of different notations of numbers in Chinese readers

The spatial component of numerical and ordinal information has been explored in previous research. However, how such mapping emerges and how it is affected by the learning experience are issues still under debate. In the current study, we examined the orientation of the mental number line for different numerical notations (e.g., “1”, “—-”, “”) in Chinese readers. Our data demonstrated that Arabic numbers are mentally aligned horizontally with a left-to-right directionality, while Chinese number words are aligned vertically with a top-to-bottom directionality. These findings indicate that different notations of the same concept have flexible mappings within space, which is plausibly shaped by the dominant context in which the numerical notations appear.     

书写表达及其对身心健康的作用

作为心理干预方法, 书写表达是通过书写披露和表达与个人重要经历有关的感受和想法, 由此促进身心健康。书写表达操作简便, 对身心健康均具有显著的促进作用, 但其干预效果会受干预对象的心理特征、卷入水平和书写主题等因素的影响。书写表达的作用机制主要是暴露、适应、注意转向和认知重构。     

Physiological and cognitive effects of expressive dissonance

Emotional well-being depends in part on affect modulation. The present study extends research on emotion regulation by assessing the physiological and cognitive effects of a novel response-focused regulation strategy, termed 'expressive dissonance.' Expressive dissonance refers to the incongruence between an emotional state (e.g., sadness) and a behavioral expression (e.g., a smile). Fifty-five participants watched a series of sad film clips in which they were asked to either naturally watch or express the opposite of what they were feeling. Results suggest that persons using the expressive dissonant strategies evidenced greater sympathetic arousal and performed worse on subsequent memory tasks than persons in the natural-watch conditions.     

新HSK书写成绩可靠性影响因素的概化理论分析

本研究以概化理论为视角,搜集了新HSK五级模拟书写题的作答和评分数据,估算了题型、题量、评卷员人数、评阅速度等潜在影响效应的方差分量,考察了新HSK书写成绩的可靠性,并探索了改善该分数可靠性的途径。基于概化理论和规划求解的数据分析发现了题量的调整方案以及题型、题量、评卷员人数的最优组合方案。本研究对评阅速度进行的分析属于前沿性的理论探索,而其他数据分析结果,则可能有益于旨在改进该测试质量的决策实践。     

叙事医学视阈下的文学与医学课程教学探索

介绍了北京大学医学部的文学与医学导论课程的教学探索。课程主要以文学作品为依托,通过文学作品中的涉医话题,如医学生的教育和成长、生死教育、医生形象、疾病叙事等,培养医学生的共情能力、伦理决策能力、临床想象力、语言和非语言沟通技巧、反思能力、疾病体验能力等。经过逐步调整和完善,形成了模块化教学、研讨班形式、反思性写作、全球竞争力提升和教学促科研等特色,并反思了遇到的挑战,展望了未来发展空间,以期为更多的文学与医学教学实践提供借鉴。     

发展性协调障碍与书写困难个案研究

该研究对一个14岁书写困难儿童zl的动作和认知技能进行了系统的考察。zl的书写困难主要表现在以下几方面：书写速度慢,字与字之间的空间距离非常近,字迹难以辨认,笔画顺序混乱。该研究首先测查了zl的基本智能和一系列精细动作技能、视觉、视空以及序列加工能力。结果发现他的基本智能、视觉加工能力正常,动作技能和视空加工能力皆显著落后于控制组儿童。语言能力测试发现,他的识字量、阅读理解和听力理解均正常。他在汉字单字、双字词、数字和图片命名上的正确率与控制组没有显著差异,但命名速度明显慢于控制组。神经生理检查发现,他的脑电波轻度异常,核磁共振扫描(MRI)显示双侧脑室体后部和枕角周围白质和小脑发育异常。这些结果表明该儿童的书写困难是更广泛的动作协调障碍的一种体现,并可能以他的脑神经发育状况为基础。文章讨论了zl书写障碍的认知神经机制及对书写障碍早期鉴别和训练的意义。     

Women's experiences of the therapeutic value of writing about pregnancy sickness

Background

There is evidence of the beneficial effects of writing therapy in relation to a range of disorders. This is the first study to evaluate those effects in the field of pregnancy sickness.

Aim

To analyse the experiences of women using writing therapy to address issues associated with pregnancy sickness.

Method

Ten women with an age range of 32–48 years participated in this research study. All had been hospitalised at least once with severe pregnancy sickness symptoms in the form of hyperemesis gravidarum. Participants were invited to write reflectively about their former pregnancy sickness, at home, and then take part in a qualitative, semi‐structured telephone interview of approximately one hour to talk about how they experienced this writing process.

Findings

Thematic analysis identified several themes relating to the beneficial effects and uses of writing therapy and women's relational need to be heard and supported.

Discussion

This study supports previous findings about the beneficial effects of writing therapy and contributes new knowledge to the field of pregnancy sickness vis‐à‐vis the importance of emotional expression, emotional care and emotional recovery. The findings have important implications for healthcare professional practice.
