如何建立聊天机器人与用户间的数字治疗联盟：关系线索的作用

近年来,研究者们将“治疗联盟”(Therapeutic Alliance,TA)的概念与在线自助干预(Internet-based Self-help Interventions,ISIs)相结合,以解决ISIs中用户参与度较低的问题。这种在数字环境中形成的TA,被称之为“数字治疗联盟”(Digital Therapeutic Alliance, DTA)。随着人工智能的迅速发展,聊天机器人可模拟人类指导,相对于传统ISIs程序更易于与用户建立关系,可通过友好、尊重、倾听、鼓励、真诚、理解、信任这几个关系线索来促进DTA的发展,为解决用户低参与度的问题提供了一种新思路。未来的研究可从影响因素、ISIs技术迭代、测量规范、实验操纵等方面对DTA作进一步的探索。     

全球正义:问题与焦点

自罗尔斯<正义论>问世之后,全球正义(global justice)研究在西方学界逐渐兴起.近年来,面对日益加快的全球化进程及其给全球秩序所带来的挑战,我国不少学者也开始关注全球正义问题.何谓全球正义?全球正义研究的主要流派有哪些?全球正义是否有实现的可能?本文拟结合国内外的有关研究,对这些问题做一初步梳理和分析.     

某些妇女的信仰不容忽视

近期,笔者观察了一些寺庙举行的宗教活动,发现参与者之绝大多数是50岁以上的妇女,其中既有下岗失业工人,也有退休干部,还有共产党员。可以说,除了退休干部以外,大都属于弱势群体。她们在激烈的竞争     

When two sources of fluency meet one cognitive mindset

Fluency, the subjective experience of ease associated with information processing, has been shown to affect a host of judgments. Previous research has typically focused on specific factors that affect the use of a single, specific fluency source. In the present study we examine how cognitive mindsets, or processing modes, moderate fluency emanating from two simultaneous sources of fluency. As a cognitive mindset manipulation, participants performed Jacoby's process dissociation paradigm. Subsequently, participants engaged in a metamemory task that incorporates (and can separately measure the influence of) two simultaneous sources of fluency: familiarity and accessibility. Our results confirmed that our content-unrelated mindset procedure had affected the use of fluency. Moreover, the use of both fluency sources was attenuated, demonstrating the generality of the effect. The findings highlight the causal dependency of fluency on a complex, cognitively-rich environment.     

健康城市建设的新理念及其导向

健康城市的理论与实践的发展以及人类对健康及其决定因素认知的深入使健康城市的内涵和理念不断扩充,吸纳了健康的社会模式及健康决定因素的理念,为健康城市建设注入了新的机制,并成为健康城市建设发展的新导向.我国建设健康城市的实践,从基线评估、规划制定到建设推进,已着力体现国际上健康城市的新理念和导向.     

性激素对人类择偶偏好的影响

择偶是一种重要的心理、社会和文化现象,婚恋择偶除了会受当下社会文化习俗等人文因素的影响,也受到个体生理机制的影响。本文聚焦热点,从进化心理学的角度阐述性激素对人类择偶偏好的影响。女性的择偶偏好受生理周期激素变化的影响,男性的择偶则会因为体内睾酮含量的不同而发生变化。性激素不仅影响人的心理和行为,还会影响人类择偶决策的神经机制。未来的相关研究应关注生理周期的测定方法、被试的文化背景和个体间的差异等。     

Temporal Discounting Mechanisms of Future‐oriented Coping: Evidence from Delay Discounting and Task Prioritization Paradigms

Four studies were conducted to examine the relationship between future‐oriented coping and temporal discounting under different situational conditions. In Study 1, 138 participants were primed with either stressful or neutral stimuli, followed by a delay‐discounting task. In Study 2, 118 participants were primed with either stressful or neutral stimuli, followed by a task‐prioritization activity. The results of both studies indicated that future‐oriented coping had a significant negative association with temporal discounting or the number of rational choices in the neutral‐priming condition, but the relationship was not significant in the stress‐priming condition. In Study 3, qualitative data revealed that the major reason for shifting choices from larger but later payoffs to smaller but sooner rewards in a stressful condition was to reduce the stressful mood, create a positive mood, and promote a sense of accomplishment. This explanation was corroborated by Study 4, in which one group was allowed to choose an immediate payoff and the other group was blocked from choosing that immediate payoff. We confirmed that post‐test anxiety was significantly lower in the immediate payoff group compared with the delayed‐payoff group in proactive and preventive coping, using pre‐test anxiety as a covariate. Preventive coping helped to reduce anxiety levels in a stressful condition only when there was a choice to obtain an immediate payoff. These findings underscore the relationship between future‐oriented coping and temporal discounting, as well as the flexibility of discounting in the face of stress.

群组发展模型——干预研究的新方法

群组发展模型(group-based trajectory model,GBTM)是一种用于研究群体异质性的新方法,旨在识别群体内遵循不同发展轨迹的亚组,并描绘亚组成员特征。这一模型为干预研究提供了新的研究视角,群组发展模型不仅可以探讨干预是否引起分组比例变化,也关注干预对个体的发展轨迹的影响,并评估干预对不同轨迹组的效果差异。
