重大传染病感染患者的道德创伤隐患研究

重大传染病疫情背景下,病原体的不断变异、疫苗保护效力的不确定性以及诸多后遗症会导致疫情难以控制,并且造成一个数量极其庞大的特殊弱势群体—感染患者。在感染患者从疑似患病到康复的期间,影响他人工作生活、恶化疫情防控形势、感染他人、亲友的抛弃、传染病污名化、医疗资源分配不均以及社会的歧视与排挤等潜在的道德创伤源会对其内心原本的道德体系产生巨大的冲击,甚至改变其原有的道德认知并击溃其积极的道德情感,从而产生道德创伤。在此基础上,感染患者会因此产生一系列社会问题、信任问题、精神问题、生存问题以及诸多消极观念。

     

The social dynamics involved in recovery and return to sport following a sport-related concussion: A study of three athlete-teammate-coach triads

An athlete's connection to their team and team members is an important part of their sport experience. However, researchers currently know little about the nature of these social dynamics with respect to concussed athletes. Our study explored athletes' recovery and reintegration into the team environment following a sport-related concussion. We conducted semi-structured interviews with each member of three athlete-teammate-coach triads (N = 9). We analysed the data using thematic narrative analysis and present the results as three stories that focused on each athlete's experience. For Cassie, we found two major plot points in her story: the transition in her role (and shift in identity) from athlete to student assistant coach/team manager and, once recovered, back to an athlete on the team. For Jess, we found that the main plot in her story was “pressure”. Specifically, the interplay between internal (placed on herself) and external (perceived from teammates and coaches) pressures to return to sport. In the third and final story, the main plot point was the tensions that arose from Jaden's preferences for social support and the type of support that his teammates and coaches believed he needed during his recovery. Our results highlight the interplay between athlete's personal and social identities, feelings of pressure to return and readiness, and the challenges of providing the right amount and type of social support. This research contributes to our limited understanding of the social dynamics involved in athletes' return to sport following a concussion.     

A systematic review of the effectiveness of machine learning for predicting psychosocial outcomes in acquired brain injury: Which algorithms are used and why?

Clinicians working in the field of acquired brain injury (ABI, an injury to the brain sustained after birth) are challenged to develop suitable care pathways for an individual client’s needs. Being able to predict psychosocial outcomes after ABI would enable clinicians and service providers to make advance decisions and better tailor care plans. Machine learning (ML, a predictive method from the field of artificial intelligence) is increasingly used for predicting ABI outcomes. This review aimed to examine the efficacy of using ML to make psychosocial predictions in ABI, evaluate the methodological quality of studies, and understand researchers’ rationale for their choice of ML algorithms. Nine studies were reviewed from five databases, predicting a range of psychosocial outcomes from stroke, traumatic brain injury, and concussion. Eleven types of ML were employed with a total of 75 ML models. Every model was evaluated as having high risk of bias, unable to provide adequate evidence for predictive performance due to poor methodological quality. Overall, there was limited rationale for the choice of ML algorithms and poor evaluation of the methodological limitations by study authors. Considerations for overcoming methodological shortcomings are discussed, along with suggestions for assessing the suitability of data and suitability of ML algorithms for different ABI research questions.     

Female and male soccer players recruited different cognitive processes when generating creative soccer moves

Previous research has indicated that in several domains, women and men may use different cognitive processes along with different neurophysiological activation to achieve similar behavioral performance. The present study extended this line of research to the novel field of soccer playing. In female and male active soccer players, we investigated patterns of brain activation and functional connectivity of brain networks during imagination of creative soccer moves, using EEG methods that are well established in creativity research. Participants were presented with scenarios taken from real soccer games. Female and male soccer players showed comparable creative performance in their imagined moves to score a goal, which was rated by top qualified experts (UEFA A licensed soccer coaches). Notwithstanding, they differed with respect to their brain activation and functional connectivity of brain networks. While men exhibited relatively higher parietal/occipital task-related EEG alpha power, women showed significantly higher within-hemisphere functional coupling in the upper alpha band. The findings add important new evidence to the field of cognitive gender research in an applied, sports-related domain of creative cognition.     

客体工作记忆任务中大脑皮层活动的记忆负荷效应

利用128导事件相关电位技术,采用延迟匹配任务的实验范式,测查了20名正常被试完成不同负荷客体任务时的皮层慢电位（slow cortical potentials,简称sp成分）,实验发现：背侧前额叶在刺激呈现后的700ms到1400ms出现记忆负荷效应,高负荷任务诱发的sp成分显著负于低负荷任务;低负荷任务诱发的sp成分在左前额区（500~1800ms）、左前额-中央区（700~1800ms）、左中央-顶叶区（1000~1400s和1800~4800ms）、右前额区（1800~4800ms）和右前额-中央区（1400~4800ms）显著负于高负荷任务,出现记忆负荷效应,但这种负荷效应在左右大脑半球所反映的心理意义可能不同     

Neurophysiological marker of inhibition distinguishes language groups on a non-linguistic executive function test

Successful interaction with the environment depends on flexible behaviors which require shifting attention, inhibiting primed responses, ignoring distracting information, and withholding motor responses. These abilities, termed executive function (EF), are believed to be mediated by inhibitory processes in the frontal lobes. Superior performance on EF tests (i.e., faster reaction times (RT), and fewer errors) has been shown in bilinguals compared to monolingual speakers. However, findings are inconsistent, and no study has directly linked this bilingual advantage to frontal lobe inhibitory processes. To clarify this uncertainty, we concomitantly tested neural inhibitory processes and behavioral responses on an EF test in bilinguals and monolinguals. Specifically, we compared English monolinguals (N = 15) to Spanish/English bilinguals (N = 13) on event-related brain potentials (ERP) during a non-linguistic, auditory Go/NoGo task, a task linked to non-motor, cognitive inhibition in monolinguals. Participants responded with a button press on trials in which target tone-pairs (Go trials) were presented and withheld their responses on non-target trials (NoGo trials). Results revealed significantly greater inhibition (i.e., greater mean N2 amplitude) in bilinguals compared to monolinguals during NoGo trials even though both groups performed the task equally well (i.e., withheld a motor response). On Go trials where participants pressed a response button, neither ERPs nor RT distinguished the groups. Additionally, scores on a second language proficiency test (i.e., English in our bilingual group) were positively correlated with N2 amplitude. These findings are the first to directly link this bilingual advantage to a neural correlate of inhibition and to reveal that inhibition in bilinguals is moderated by second language proficiency. Results are discussed in the context of plasticity, and we propose that evaluating bilinguals at varying levels of second-language proficiency may serve as a model of human neuroplasticity.     

心理学视角下的极端膜拜伤害问题

对极端膜拜团体造成身心伤害现象的科学研究, 集中在对极端膜拜伤害的界定、测量和机制三个方面。本文的目的, 是梳理这三个主题上的研究脉络, 明晰其中的争议之处和取得的成绩。文本分析表明, 对极端膜拜伤害的界定从“洗脑”转向了“心理虐待”, 对这类伤害的经验观察由个体症状转向了群体行为和经历的描述, 测量方法由传统心理测试工具变成了新型团体心理虐待量表, 膜拜伤害的心理机制研究在综合环境和个人精神特质两种因素的基础上建立了二者交互的病理模型, 表观遗传学和人际神经生物学用于极端膜拜伤害的生理机制研究已见端倪。但是, 迄今对于极端膜拜伤害的学术研究尚未形成范式。

道德韧性是成功应对道德逆境的高尚道德操守。面对新型冠状病毒感染的肺炎疫情,中华民族的道德韧性得以彰显,有效地遏制了道德创伤的发生;但社会个体道德韧性的缺失,也使得部分道德创伤不容忽视,如果任其恣意蔓延必将消解和冲击人们抗击疫情的道德情感和道德意志。抵御疫情中的道德创伤,必须在坚定文化自信中传承道德韧性,在应对道德逆境中塑造道德韧性,在探寻生命意义中升华道德韧性,在领导和权威人士履职尽责中激发道德韧性。     

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.
