The typology of parricide and the role of mental illness: Data-driven approach

Parricide is a rare type of homicide in which mental illness is often an important factor. The aims of this study were (a) to describe the characteristics of parricide offenders with a focus on mental illness and clinical care and (b) to examine Heide's widely used typology of parricide through a data-driven approach. We analyzed all homicides in England and Wales between 1997 and 2014. Parricide offenders in our sample were most often male, unmarried, and unemployed, with a third of offenders diagnosed with schizophrenia; 28% had been in contact with mental health services before the offense. The latent class analysis resulted in three types of parricide offenders: middle-aged with affective disorder, previously abused, and seriously mentally Ill, which confirmed, to an extent, Heide's typology. Health and social care services should actively engage with carers of people with mental illness and support to those caring for older relatives and victims of abuse.     

群体认同对群际敏感效应及其行为表现的影响

通过实验研究了群际互动中个体对不同来源身份的消极群体评价的情绪反应及群体认同的调节作用, 并从情绪-行为反应的连续性视角探索群际敏感效应的行为表现及内在机制。结果发现:(1)相比内群体的消极群体评价, 外群体的消极群体评价更能引起消极情绪反应; (2)群体认同对群际敏感效应起调节作用, 高群体认同者对来自外群体消极评价的情绪反应更加负面, 而低群体认同者这种趋势并不明显; (3)高群体认同者在经历外群体的消极群体评价后会表现出更多的内群体积极行为, 且消极情绪反应对此起中介作用。研究扩展了群际敏感效应的适用范围, 并为探讨其内部机制和后续影响提供了新的研究思路。     

关系认知与善意认知对大学生人际信任的影响

采用投资博弈,以大学生为被试探讨关系认知（亲疏关系、阶层关系）和特质认知（以善意为例）对中国人人际信任的影响。结果发现,亲疏关系认知、阶层关系认知和善意认知都会影响中国人的人际信任。关系越近、阶层越高、越善意,信任水平越高。随着亲疏关系下降或善意降低,阶层关系对信任水平的作用之间的差异逐步减弱。亲疏关系认知和阶层关系认知存在交互作用,亲疏、阶层和善意也具有交互作用。人们对上位阶层的信任大于平位大于下位,但是当信任对象存在低善意特质或陌生人身份时,人们对上位阶层的信任会下降至和平位没有差异;当低善意特质和陌生人身份同时存在时,人们对上位、平位和下位的信任无差异。     

经济不平等对阶层流动感知的影响及其机制

经济不平等是影响阶层流动感知的重要因素。研究发现,经济不平等可能抑制、也可能提升阶层流动感知。在梳理两者之间复杂关系的基础上,本文提出了经济不平等影响阶层流动感知的作用机制模型。经济不平等可能通过影响不同的心理过程,继而对阶层流动感知产生抑制或提升作用;此外,两者关系也会受到微观个体因素和宏观社会因素的调节,从而呈现出不同的关系模式。未来研究应进一步考察和完善经济不平等影响阶层流动感知的整合模型。     

来源记忆中背景的情绪效价与唤醒对提取过程的影响

以往研究表明情绪背景对来源记忆存在影响,但背景的情绪效价和唤醒如何影响熟悉性及回想尚存争议。本研究以ERPs技术作为测量手段,采用来源记忆多键范式,操纵背景的情绪效价及唤醒强度,以探讨编码阶段背景情绪影响来源记忆提取的认知神经机制。学习阶段,呈现中性汉字及情绪图片（正性高唤醒、正性低唤醒、负性高唤醒、负性低唤醒）;测验阶段,仅呈现汉字,被试进行五键判断。行为结果发现：来源正确的比率比来源错误的比率更高,反应时更短;同时提取正性背景的辨别力更强,反应时更短;提取高唤醒背景反应时更短。脑电结果发现了分别代表熟悉性及回想的FN400及LPC新旧效应,且在500～700 ms,提取正性背景及高唤醒背景诱发显著更正的ERPs,但效价与唤醒没有交互作用。总体来说,来源记忆中背景效价及唤醒度对回想过程存在独立影响,体现为正性背景及高唤醒背景对来源提取的促进作用。     

主观社会阶层对亲环境行为的影响: 物质主义价值观的中介作用

研究旨在通过两个实验分别探讨主观社会阶层对亲环境行为的影响及作用路径.结果发现:(1)主观社会阶层对亲环境行为具有显著正向影响,即主观社会阶层感知高的个体更愿意保护环境并为环境活动贡献金钱.(2)物质主义价值观在社会阶层影响亲环境行为中起完全中介作用,即高社会阶层的个体物质主义程度较低并更加亲环境,而低社会阶层的个体则...     

Sea lions and equivalence: expanding classes by exclusion

Experiments have shown that human and nonhuman subjects are capable of performing new arbitrary stimulus-stimulus relations without error. When subjects that are experienced with matching-to-sample procedures are presented with a novel sample, a novel comparison, and a familiar comparison, most respond by correctly selecting the novel comparison in the presence of the new sample. This exclusion paradigm was expanded with two California sea lions that had previously formed two 10-member equivalence classes in a matching-to-sample procedure. Rather than being presented with a novel sample on a given trial, the sea lions were presented with a randomly selected familiar member of one class as the sample. One of the comparisons was a randomly selected familiar member of the alternative class, and the other was a novel stimulus. When required to choose which comparison matched the sample, the subjects reliably rejected the familiar comparison, and instead selected the unfamiliar one. Next, the sea lions were presented with transfer problems that could not be solved by exclusion; they immediately grouped the new stimuli into the appropriate classes. These findings show that exclusion procedures can rapidly generate new stimulus relations that can be used to expand stimulus classes.     

The competition-among-relations-in-nominals theory of conceptual combination: implications for stimulus class formation and class expansion

One way in which new concepts are added to the conceptual system is through conceptual combination. The competition-among-relations-in-nominals (CARIN) theory (Gagné & Shoben, 1997) proposes that conceptual combination involves specifying a thematic relation (e.g., noun MADE OF modifier) to link the constituent concepts (e.g., chocolate and bee). This theory claims that relations have different strengths for various concepts that correspond to how often a modifier and relation have been paired in previous encounters with combined concepts and that this relational knowledge strongly affects the ease with which combined concepts can be formed. A mathematical model that incorporates key claims of the theory is presented, and empirical findings that are relevant to evaluating the CARIN theory are reviewed. The parallels between the CARIN theory and approaches to stimulus class formation are also discussed.     

Hotep's Story: Exploring the Wounds of Health Vulnerability in the US

A wide variety of forms of domination hasresulted in a highly heterogeneous health riskcategory, ``the vulnerable.' The study of healthinequities sheds light on forces thatgenerate, sustain, and alter vulnerabilities toillness, injury, suffering and death. Thispaper analyzes the case of a high-risk teenfrom a Boston ghetto that illuminatesintersections between ``race' and class in theconstruction of vulnerability in the US.Exploration of his ``wounds' helps specify howlarge-scale social and cultural forces becomeembodied as individual experience of disparatehealth risk. The case demonstrates that healthinequities would not occur if resources –employment, income, wealth, education, housing,profiling in the legal system, and health care– were more justly managed in keeping withstandards outlined in the Universal Declarationof Human Rights. Professional responses to the``wounds of vulnerability' may reveal importantaspects of who we are and what our work asscholars, practitioners, and advocates mustbecome.     

Sets and Classes as Many

In this paper the view is developed that classes should not be understood as individuals, but, rather, as classes as many of individuals. To correlate classes with individuals labelling and colabelling functions are introduced and sets identified with a certain subdomain of the classes on which the labelling and colabelling functions are mutually inverse. A minimal axiomatization of the resulting system is formulated and some of its extensions are related to various systems of set theory, including nonwellfounded set theories.
