自然语言处理预测抑郁症的技术陷阱与道德风险

抑郁症患者倾向于在网络社交平台上发布带有抑郁信号的推文。基于这些文字信息，借助自然语言处理进行分析，提取归纳用户的语言特征，可以预测潜在用户的抑郁症状况。由于隐私信息的敏感、相关技术的不成熟等原因，出现了诸如信息获取与隐私侵犯、算法偏见与信息误判、信息权利与信息利益、责任界定与权限模糊等现实问题，成为进一步发展的掣肘。进行算法技术升级、完善法律法规、加强行业伦理约束等是避免道德风险的重要措施。     

不同社交媒体使用目的对员工工作绩效的影响机制

基于工作要求-资源理论, 本研究探讨了两种社交媒体使用目的对员工工作绩效影响的内部作用机制, 进而分析两种社交媒体使用目的对员工工作绩效的影响效果。通过369份“领导者-下属”匹配数据, 研究发现：(1)基于工作、社交的社交媒体使用均促进员工工作绩效; (2)基于工作、社交的社交媒体使用均通过工作投入影响工作绩效, 基于社交的社交媒体使用还通过关系冲突影响工作绩效; (3)社交媒体的工作使用和社交使用对员工工作绩效的影响存在相互替代关系。本研究结果不仅从理论上拓展了社交媒体使用的研究视角, 为后续研究提供新的理论框架, 同时通过比较分析为组织管理社交媒体使用提供了新思路。     

基于网络分析的抑郁症产生与演变预测

抑郁症是现代社会亟需解决的公共健康问题,预防是应对该问题最有效的方式之一。有效预防的关键在于准确识别潜在抑郁症患者,捕捉抑郁状态发生变化的预警信号,及时采取预防措施。抑郁是由多种症状相互作用而成的网络系统,该网络的结构特征和动力特征能为抑郁症发生与演变的预测提供新的理论视角和可测量的指标。以如何预测抑郁症发生与演化的关键问题为切入点,从理论的角度论述症状网络与抑郁的关系,进一步考察抑郁症状网络的拓扑结构特征、临界现象相关指标在预测抑郁发作及突变中的表现力。为增加早期预警信号在抑郁状态预测方面的准确性,未来研究应当构建更系统、全面的网络,通过使用综合的或基于机器学习的预警指标,优化抑郁状态确定方法。     

社交媒体使用对执行功能的影响：有益还是有害?

社交媒体使用对执行功能的影响尚存争议, 这与社交媒体使用强度起到的调节作用有关。中等强度的社交媒体使用会产生社交媒体心流体验, 使注意集中于目标信息, 并为个体提供了持续不断的社会奖励和情感支持, 对执行功能有益, 但高、低强度社交媒体使用则会损害执行功能。今后该领域的研究应该探讨社交媒体使用影响执行功能的“剂量效应”以及社交媒体使用类型对执行功能的具体影响, 还应关注不同认知水平的个体, 以进一步明确社交媒体使用与执行功能发展的关系。     

抑郁症患者识别情绪词时执行功能实验研究

为了研究抑郁症患者识别汉语情绪词时的执行功能特征,采用神经扫描仪STIM刺激反应系统记录16名抑郁症患者和18名正常对照组执行四类Go／No go汉语情绪词识别作业时的反应时和正确率,抑郁自评量表(SDS)评价抑郁严重程度,自动思维问卷(ATQ)评价负性认知偏差程度。结果发现,识别正／负性词时抑郁症组反应时均明显延长,正确率明显降低。组内方差分析显示,随着情绪词识别作业难度增加,正常对照组正／负性词反应时缩短,正确率逐渐提高,且不受双重作业任务的影响。抑郁症组则表现为反应时延长,正确率变化不明显。重复测量多因素方差分析显示。词性、作业、组别间因素对反应时的主效应均有显著性意义;组别间因素对正确率的主效应均有显著性意义。抑郁症患者SDS、ATQ分与反应时、正确率相关无显著性。提示抑郁症患者区分正负性汉语情绪词时存在执行功能障碍。     

基于QQ空间的社交网站使用对青少年抑郁的影响:上行社会比较和自尊的序列中介作用

为探讨社交网站(QQ空间)使用对青少年抑郁的影响及其作用机制,在社会比较和抑郁易感性模型的视角下,采用社交网站使用强度问卷、上行社会比较问卷、自尊量表和抑郁量表,对964名中学生进行调查。结果表明:(1)在控制了性别、年龄以及社交网站使用年限后,社交网站使用对抑郁和社交网站中的上行社会比较都有显著的正向预测作用;(2)社交网站使用能通过社交网站中的上行社会比较和自尊的中介作用对抑郁产生影响,且该中介作用包含了两条路径——上行社会比较的单独中介作用以及上行社会比较-自尊的链式中介作用。本研究揭示了社交网站使用与抑郁的关系及其作用机制,深化了社交网站使用对个体影响的研究。     

网络社交媒体使用与老年人孤独感关系的元分析

已有研究从不同理论视角考察网络社交媒体使用和老年人孤独感的内在联系,但结果不尽一致。本研究采用元分析方法对二者关系进行探讨,使用随机效应模型对检索后获得的39项研究(49个效应值)进行元分析。结果发现：网络社交媒体使用与老年人孤独感、情绪孤独感和社交孤独感存在显著负相关。网络社交媒体使用与老年人孤独感的关系受到网络社交媒体测量指标和孤独感测量工具的调节作用,但不受性别和文化背景的影响。本研究为老年人网络社交媒体使用与孤独感的关系提供了较为精确的估计,也澄清了二者相关性大小和方向不一致的分歧,对于引导老年人合理使用网络社交媒体进而缓解孤独感具有重要意义。     

反馈相关负波：一种抑郁症的生物标记物

反馈相关负波(feedback-related negativity, FRN)是一种反映个体奖赏敏感性的脑电成分; 而抑郁症患者的特征之一是奖赏敏感性的减弱。大量横向研究发现了重度抑郁症患者(major depressive disorder, MDD)及有患抑郁症风险群体的FRN异常; 另外, 纵向研究发现FRN的异常能够预测青春期抑郁发作及抑郁症状发展, 压力、睡眠等因素在其中起调节作用。这提示FRN可能在对抑郁症的诊断及分型、抑郁高危群体的筛查及干预等方面具有潜在价值。目前关于FRN的心理功能依然存在一些争议, 在未来的研究中应该进一步明确FRN的功能和测量方法, 并探明抑郁症的异质性和共病对FRN的作用, 也应关注老年人群体中FRN与抑郁症的关系。     

被动性社交网站使用与初中生抑郁的关系：链式中介效应分析

为探讨被动性社交网站使用、冗思、核心自我评价与初中生抑郁的关系,本研究采用被动性社交网站使用问卷、冗思问卷、核心自我评价问卷以及流调中心用抑郁量表对673名初中生进行调查研究。结果显示：（1）被动性社交网站使用与冗思和抑郁均呈显著正相关,而与核心自我评价呈显著负相关;核心自我评价与冗思、抑郁呈显著负相关;冗思与抑郁呈显著正相关;（2）被动性社交网站使用不仅对初中生抑郁具有显著的直接预测作用,而且能够通过三种间接效应对抑郁产生影响,即核心自我评价的单独中介作用、冗思的单独中介作用以及二者的链式中介作用。     

青少年孤独感与抑郁症状:反应风格的中介作用以及性别的调节作用

Language use in the Adult Attachment Interview: Evidence for attachment‐specific emotion regulation

Adult attachment classification is traditionally based on qualitative coding of participants' discourse about their attachment history. Word count‐based analyses have proven useful for assessing emotional states from narrative. To expand the understanding of how language is used in emotion regulation processes related to attachment, the authors assess 102 college‐aged adults' language on the Adult Attachment Interview (AAI). Autonomous adults use more emotion words and, in particular, negative emotion words. Preoccupied adults use more anger words. Disorganized adults use more experientially connected language and more death/dying words, but also use more second‐person pronouns when discussing loss. Language use during the AAI explains variability in self‐reported emotional distress above and beyond attachment classifications. Results are discussed in terms of their relevance to emotion and attachment.     

Somatic and social: Chinese Americans talk about emotion

Empirical findings suggest that Chinese and Americans differ in the ways that they describe emotional experience, with Chinese using more somatic and social words than Americans. No one, however, has investigated whether this variation is related to differences between Chinese and American conceptions of emotion or to linguistic differences between the English and Chinese languages. Therefore, in two studies, the authors compared the word use of individuals who varied in their orientation to Chinese and American cultures (European Americans [EA], more acculturated Chinese Americans [CA], and less acculturated CA) when they were speaking English during emotional events. Across both studies, less acculturated CA used more somatic (e.g., dizzy) and more social (e.g., friend) words than EA. These findings suggest that even when controlling for language spoken, cultural conceptions of emotion may shape how people talk about emotion.     

Form is easy,meaning is hard: resolving a paradox in early child language

A developmental paradox is discussed: studies of infant processing of language and language-like stimuli indicate considerable ability to abstract patterns over specific items and to distinguish natural from unnatural English sentences. In contrast, studies of toddler language production find little ability to generalize patterns over specific English words or constructions. Thus, infants appear to be abstract auditory or language processors whereas toddlers appear to be non-abstract, item-specific language users. Three resolutions are offered to this paradox. The first, that no resolution is necessary because only the toddler findings come from language use in a communicative context and so only the toddler findings are relevant to linguistic knowledge, is rejected. The second, that the contradictions are rooted in the differing methodologies of the two sets of studies (comprehension vs. production), is found to explain important aspects of the contradictory findings. The third, that the contractions come from the differing content of the stimuli in the studies, is also found to be explanatory and is argued to carry greater weight. Resolution 3 suggests that the patterns that infants extract from their linguistic input are not yet tied to meaning; thus, toddlers do not lose these earlier-abstracted forms but their use of them is limited until they have been integrated with meaning. It is argued that in language acquisition, learning form is easy but learning meaning, and especially linking meanings and forms, is hard.     

Cultural perspectives on the linguistic representation of emotion and emotion events

It is argued that the linguistic representation of emotions and events giving rise to them is influenced by the cultural regulation of the relationship between a person and others. Such cultural variations are expected to be reflected in how emotions and emotion events are represented in language. The two studies provide support for the hypothesis that in a culture where relationships and interdependence are valued emotion terms function as relationship-markers and emotion events are represented by the use of concrete linguistic terms when compared with cultures that emphasise the value of the individual. Moreover, we also found support for the argument that emotion terms function predominantly as self-markers in cultures that value individuality and that they are represented by more abstract terms (adjectives, nouns). The implications of these findings are discussed.     

情绪与语言加工的相互作用

情绪与语言加工的相互关系逐渐受到了研究者的重视。一方面,情绪对语言加工有着重要的影响,表现为：（1）语言中蕴含的情绪信息对语言加工的影响,包括情绪词、情绪性语句、情绪性篇章的加工;（2）情绪背景对语言加工的影响,包括自身的情绪状态背景（如,抑郁、焦虑、快乐等心境）,以及情绪语调/语境、情绪图片、音乐等外在情绪线索诱发的情绪背景;（3）内化的情绪反应模式（如身体姿势、面部表情等）对语言加工的影响。另一方面,语言对情绪加工也有着重要的影响,表现为：（1）语义概念对情绪知觉的影响;（2）语言指导在情绪学习中的作用;（3）语言在情绪调节中的作用。未来的研究应该深入探讨情绪与语言加工的相互作用的内部机制,并将基础研究和教育及临床应用结合起来。     

Emotionally avoidant language in the parenting interviews of substance‐dependent mothers: Associations with reflective functioning,recent substance use,and parenting behavior

Parenting and emotion regulation are two known, and potentially interrelated, areas of impairment among substance‐abusing mothers. In this study, we examine substance ‐abusing mothers' (positive and negative) emotion language word use during their discussion of negative parenting experiences on the Parent Development Interview for its association with reflective functioning (RF), recent substance‐use history, and sensitivity to child cues. Within a sample of 47 methadone‐maintained mothers, we evaluate the hypothesis that linguistic evidence of emotional avoidance (more frequent positive feeling words and less frequent negative emotion words) will be associated with lower RF, more recent substance use, and more insensitive parenting. Further, we evaluate whether language use mediates the association between self‐focused RF and insensitive parenting. Results of hierarchical regressions suggest that more frequent positive feeling word use, but not negative emotion word use, is associated with lower RF, more recent substance use, and lower sensitivity to child cues. Positive feeling word use partially mediates the association between self‐focused RF and insensitive parenting. Results are discussed in the context of their contribution to the literature on emotion and parenting in substance‐abusing populations.     

Am “I” more important than “we”? Couples’ word use in instant messages

Recent studies have identified robust associations between the types of words that people use and their psychological health. This study investigated whether couples’ word use in their daily instant messages (IMs) is linked to the quality and stability of their relationships. Sixty‐eight dating couples in the United States submitted 10 days of IM conversations with each other, which were analyzed with a linguistic word count program. Six months later, couples indicated whether they were still dating. Pronoun use and emotion word use both were associated with relationship satisfaction and stability. These findings extend previous research showing that the frequencies of certain words that people use are associated with the quality of their social relationships.     

Linguistic correlates of social anxiety disorder

The goal of this study was to examine the linguistic correlates of social anxiety disorder (SAD). Twenty-four individuals with SAD (8 of them with a generalised subtype) and 21 non-anxious controls were asked to give speeches in front of an audience. The transcribed speeches were examined for the frequency of negations, I-statements, we-statements, negative emotion words, and positive emotion words. During their speech, individuals with either SAD subtype used positive emotion words more often than controls. No significant differences were observed in the other linguistic categories. These results are discussed in the context of evolutionary and cognitive perspectives of SAD.     

How infants begin to extract words from speech

A crucial step for acquiring a native language vocabulary is the ability to segment words from fluent speech. English-learning infants first display some ability to segment words at about 7.5 months of age. However, their initial attempts at segmenting words only approximate those of fluent speakers of the language. In particular, 7.5-month-old infants are able to segment words that conform to the predominant stress pattern of English words. The ability to segment words with other stress patterns appears to require the use of other sources of information about word boundaries. By 10.5 months, English learners display sensitivity to additional cues to word boundaries such as statistical regularities, allophonic cues and phonotactic patterns. Infants’ word segmentation abilities undergo further development during their second year when they begin to link sound patterns with particular meanings. By 24 months, the speed and accuracy with which infants recognize words in fluent speech is similar to that of native adult listeners. This review describes how infants use multiple sources of information to locate word boundaries in fluent speech, thereby laying the foundations for language understanding.
