厌恶情绪与自杀行为的关系

自杀导致人类死亡的人数与日俱增,然而自杀的心理机制却并不清楚。最近研究发现,厌恶情绪是导致自杀的主要情绪因素,个体因为自身厌恶而走向自杀。厌恶情绪是一种对自己和他人排泄物等反感的基本情绪,促进个体远离毒性和疾病,从而产生“免疫行为”。许多心理问题来自于对周围人或事物的厌恶,有自杀行为的个体对自身极其厌恶,说明他们的厌恶情绪出现了问题。如同躯体免疫攻击自身一样,自身厌恶是自杀意念的关键因素,早年创伤是其根源,生活压力和精神疾病也参与厌恶诱发自杀意念。厌恶诱发自杀意念的神经基础与HPA轴和五羟色胺系统有关。未来研究可利用神经影像和电生理等神经科学技术,检验自杀行为的神经机制,探讨厌恶情绪影响自杀行为的心理和神经机制。     

Brain bases of English morphological processing: A comparison between Chinese-English,Spanish-English bilingual,and English monolingual children

How do early bilingual experiences influence children's neural architecture for word processing? Dual language acquisition can yield common influences that may be shared across different bilingual groups, as well as language-specific influences stemming from a given language pairing. To investigate these effects, we examined bilingual English speakers of Chinese or Spanish, and English monolinguals, all raised in the US (N = 152, ages 5–10). Children completed an English morphological word processing task during fNIRS neuroimaging. The findings revealed both language-specific and shared bilingual effects. The language-specific effects were that Chinese and Spanish bilinguals showed principled differences in their neural organization for English lexical morphology. The common bilingual effects shared by the two groups were that in both bilingual groups, increased home language proficiency was associated with stronger left superior temporal gyrus (STG) activation when processing the English word structures that are most dissimilar from the home language. The findings inform theories of language and brain development during the key periods of neural reorganization for learning to read by illuminating experience-based plasticity in linguistically diverse learners.     

脑机增强：公平问题及其反思

脑机接口增强性应用引起了人们的广泛热议。相比以治疗为目的的应用,当脑机接口用于增强健全人的身体和心理等功能时,所带来的问题可能更多、更复杂,容易带来公平上的问题和挑战。面对这些问题和挑战,需要辩证地分析,客观、理性地看待。从根本上讲,导致这些不公平不在技术本身。因此,需要深刻反思脑机增强公平问题产生根源的同时,也需要从两方面予以应对,一是重视脑机增强的公平风险,二是明确脑机增强的使用范围,避免滥用。     

Claudia Card's Concept of Social Death: A New Way of Looking at Genocide

Scholarship in the multidisciplinary field of genocide studies often emphasizes body counts and the number of biological deaths as a way of measuring and comparing the severity and scope of individual genocides. The prevalence of this way of framing genocide is problematic insofar it risks marginalizing the voices and experiences of victims who may not succumb to biological death but nevertheless suffer the loss of family members and other loved ones, and suffer the destruction of relationships, as well as the foundational institutions that give rise to and sustain those relationships. The concept of social death, which Claudia Card offers as the central evil of genocide, marks a radical shift in conceptualizing genocide and provides space for recovering the marginalized voices of many who suffer the evils of genocide but do not suffer biological death. Here her concept of social death is explored, defended, and criticized.     

Fears of death and fears of dying in the counter-transference

It is commonplace for people to say they are not afraid of death but they are afraid of dying. I discuss unconscious aspects of fears of dying and fears of death which are revealed in counter-transference experiences in therapy with people suffering from terminal illnesses and with older people. Studying the counter-transference shows that fears of dying, which usually refer to lingering and disabling illnesses, unconsciously are linked with fears of dependency and the apprehension that if one becomes dependent then no-one will want to look after you. This apprehension is often a residue of failures in the early dependency relationship which can be re-enacted in adult life through projective identification when therapists and carers may be induced to abandon the caring role. Despite the ubiquitous denial, fears of death surface in the counter-transference, often obliquely but always with a particular terror for the survival of the self. This unconscious terror confirms Freud’s insight about the denial of death that what is unthinkable is the annihilation of the self. I conclude with a discussion about the importance of setting an ending date in therapy with those who are old or terminally ill.     

Executive function outcomes of children with traumatic brain injury sustained before three years

Traumatic brain injury (TBI) is a common cause of disability in childhood. While the outcomes of TBI sustained in school years has been heavily researched, very little is known about the impact of TBI in infants and young children. The aim of this study was to investigate the impact of TBI on executive function (EF) in children who sustained a TBI before 3 years of age. A group of 55 children, 19 with a mild TBI, 16 children with a moderate-severe TBI, and 20 uninjured comparison children participated. The EF of children aged 3 to 6 years were compared using child-based measures of attentional control and information processing. Parents completed questionnaires rating their child's EF. Severity groups differed on the child-based EF measure of attentional control with children with TBI performing below the control group. There were no significant group differences for information processing or parent-rated EF. It appears that children who sustain a TBI before the age of 3 years display impairments in some areas of attentional control 3–4 years postinjury. The findings fit with the existing EF literature for older children.     

Us versus them: Understanding the process of race perception with event-related brain potentials

Race is powerful social signal, imbued with a great deal of meaning and capable of affecting a wide range of behaviours and judgements. This review focuses on the use of event-related brain potentials (ERPs) to better understand the process and implications of race perception. Research to date repeatedly demonstrates the speed and automaticity with which racial category membership is encoded. The quick and relatively obligatory encoding of racial ingroup and outgroup distinctions in turn affects a variety of subsequent racially biased behaviours. Such findings not only speak to the close link between social categorization and behaviour, but also have been used to understand how the effects of race perception can be moderated.     

Functional analysis and treatment of inappropriate sexual behavior

The results of a functional analysis showed that inappropriate sexual behaviors exhibited by a 9-year-old boy who had been diagnosed with traumatic brain injury were maintained by positive reinforcement in the form of social attention. An intervention consisting of functional communication training and extinction resulted in reduced levels of inappropriate sexual behaviors.

The effects of sport dance on brain connectivity and body intelligence

Dancing is characterised by physical movement in accordance with rhythm perception. Twelve sport dancers and 12 age- and sex-matched young adults who had no dance experience (control group) were recruited. Body intelligence and brain activity were assessed in both groups using the Body Intelligence Scale (BIS) and resting state functional magnetic resonance imaging. BIS scores of dancers were higher than those of control subjects. The dancer group showed increased functional connectivity from the precentral gyrus to the right cingulate gyrus, right occipital fusiform gyrus, right inferior frontal gyrus, right medial frontal gyrus, left inferior frontal gyrus, right parietal postcentral gyrus, and right frontal lobe compared with control subjects. Sport dancers had increased body intelligence sensitivity compared with matched controls. In addition, the characteristics of dance, including physical movement in accordance with rhythm perception, might be associated with increased brain activity in the somatosensory and rhythm perception networks.
