Suicidality among high school students in Hong Kong, SAR

Suicide is the leading cause of death in Hong Kong SAR for the youth aged 15-24. This study examined the prevalence of suicidality among secondary school students in Hong Kong using a representative, territory-wide sample of 2,586 students. Suicidal behaviors can be conceptualized as a spectrum of self-destructive behaviors. Cumulative logit model analysis indicated that a range of factors, such as unhappy family life, were associated with increasing levels of suicidality. Use of illicit drugs, inhalants, and tobacco differentiated attempters from ideators. The implications of the research findings are discussed.     

A Logic for Disjunctive Ignorance

In this paper, we introduce a notion of ‘disjunctive ignorance’, which is a weak combination of two forms of ignorance in the literature. We propose a logical language with ‘disjunctive ignorance’ as a sole modality, explore the logical properties of this notion and its related notions, and axiomatize it over various frame classes. By finding suitable reduction axioms, we extend the results to the case of public announcements and apply it to Moore-like sentences.

     

观点采择是否一定促进内隐宽恕?——受害者对伤害动机认同的调节作用

以往研究多认为观点采择可有效促进宽恕,近期研究则开始关注观点采择诱发宽恕等亲社会行为的边界条件。结合“换位体验”和内隐态度测量范式,本研究考察了受害者对伤害动机的认同在被动和自发观点采择影响内隐宽恕过程中的调节作用。实验1发现当人际伤害中存在人们无法认同的恶意不道德动机时,被动和自发观点采择都抑制了受害者对施害者的内隐宽恕且后者的抑制效应更显著。实验2则进一步操纵了不同类型受害者对施害者伤害动机的认同差异,低认同组与实验1结果相同,即被动和自发观点采择中都抑制了内隐宽恕且后者的抑制效应更显著,但高认同组在两种观点采择中都促进了内隐宽恕且二者的促进效应无显著差异。本研究揭示了伤害动机认同在不同类型观点采择影响内隐宽恕过程中起到的调节作用,进一步丰富了对观点采择和宽恕间复杂关系的认识。     

亲亲为大，亲贤仍重：亲疏关系、人情取向对人际信任的影响

本文基于以往理论,提炼出人际交往中影响信任的两大因素：关系因素和个人特质因素,通过两个情景启动实验尝试探索亲疏关系、可信赖特质（能力、善意和诚信）对人际信任的影响机制及其作用的边界条件。结果发现：亲疏关系除了可以直接预测人际信任之外,还可以通过感知被信任者的可信赖特质产生间接影响。此外,个体的人情取向可以分别调节亲疏关系对感知被信任者的能力、诚信特质的效应和通过感知被信任者的能力、诚信特质影响人际信任的间接效应,并且作用的主要对象是关系网中的熟人。本研究对理解当代中国社会在多元文化交融下的人际信任具有重要意义。     

状态焦虑与转换功能：注意控制理论在运动员群体中适用性的检验

通过3个平行实验探讨了状态焦虑对转换功能的影响,检验了注意控制理论在运动领域的适用性。3个实验采用不同范式的More-Odd shifting任务测量转换功能,其结果呈现一致的趋势：在大学生群体中,高状态焦虑降低了加工效能,而对正确率影响不大;而在运动员群体中,高状态焦虑对加工效能和正确率都影响不大。本研究得出结论：注意控制理论关于状态焦虑影响转换功能的假设可能在不同群体中有不同的适用性,适用于大学生,但不适用于运动员。     

Outcome of the Psychological Intervention Program: Internet Use for Youth

The prevalence of problematic Internet use (PIU) is reportedly higher in South East Asian adolescent populations. The exacerbation of problematic adolescent behaviors has been found to associate significantly with PIU and is expected to worsen with age. Cognitive Behavioural Therapy (CBT)-integrated therapy has been shown to significantly reduce in the presence of psychological symptoms such as depression and social anxiety. The Psychological Intervention Program-Internet Use for Youth (PIP-IU-Y) is a CBT-based program designed for adolescents and comprises of a series of interpersonal skills to improve their face-to-face interaction. It focuses on taking preventative measures against Internet addiction before it develops by addressing the participant’s PIU as a negative coping style and incorporating positive psychological techniques. A total of 157 participants between the ages of 13 and 18 completed the program which consisted of eight weekly, 90 min sessions in a group format. Treatment outcomes were measured using mean change at the end of the program and 1 month post-treatment. The majority of the participants showed improvement after the eight weekly sessions of PIP-IU-Y and continued symptom maintenance at the 1 month follow-up. An overwhelming majority of participants were able to manage PIU symptoms after the intervention program, reinforcing the efficacy of the PIP-IU-Y. Not only did it addresses the PIU behaviour but also helped in reducing social anxiety and increasing social interaction. Further research could investigate treatment differences among the various subtypes of PIU (e.g., online gaming and pornography) in order to see if treatment differences exist.     

The Acquisition of Exhaustive Pairing in Multiple Wh-Questions in Mandarin

The comprehension of paired wh-questions is examined in child Mandarin, to compare the age of acquisition with that of children speaking European languages like English and German. In Study 1, participants were 734 Mandarin speakers aged 2;6–7;11, drawn from four regions of China. Results reveal a striking parallel between the acquisition of exhaustive answers in Mandarin and that in languages with wh-movement. The significant correlation with children’s exhaustive interpretations of the universal quantifier every (dou) also parallels findings in English. In Study 2, the performance of children (N?=?100) identified as having language impairment is compared to that of non-impaired children (N?=?130), and the results support the idea that answering these paired wh-questions is a potential semantic deficit in language-delayed children.     

An Investigation of Entrepreneurs' Venture Persistence Decision: The Contingency Effect of Psychological Ownership and Adversity

We incorporate psychological ownership theory and adversity literature to examine the joint effect of psychological ownership and adversity on entrepreneurs' persistence decision. The results of two experiments and one survey show that both low adversity and high psychological ownership for the venture increase entrepreneurs' likelihood of persistence. We also identify the moderating effect of adversity. Psychological ownership is more relevant to the likelihood of persistence when adversity is high than when it is low. Our research contributes to psychological ownership theory and the entrepreneurial persistence literature and has practical implications for entrepreneurs.
