Can we learn from the clinically significant face processing deficits,prosopagnosia and capgras delusion?

This review describes two clinically significant face processing deficits, prosopagnosia and Capgras delusion, and provides new knowledge about the face recognition process by a convergence of empirical findings. These empirical findings are structured around two questions that are viewed from the perspectives of the two deficits. First is the question of hemispheric specificity, which inquires into the degree of each hemisphere's contribution to the face recognition process. Second is the question of dual neural pathways, which addresses the possibility that the face recognition process proceeds along two parallel pathways in the brain. Findings from the hemispheric specificity studies reinforce the current view that right hemisphere involvement is necessary for face recognition while left hemisphere involvement is minimal. Findings from the dual neural pathways studies reinforce the plausible but yet unproven hypothesis that two neural pathways pass information from the visual association cortex in the occipital lobe toward the temporal lobes and limbic system when faces are seen and recognized. These findings, which also indicate that each of the dual neural pathways carries different, nonredundant information, could be instrumental in showing that the pathways play different roles in the manifestations of the clinically significant face processing deficits, prosopagnosia and Capgras delusion.     

动作视频游戏对发展性阅读障碍者阅读技能的影响及其内在机制

发展性阅读障碍是一种在获得阅读技能方面的特殊困难, 这种障碍会严重影响个体的发展, 如何帮助发展性阅读障碍者改善其阅读技能是近年来研究的焦点。传统的干预方法主要针对发展性阅读障碍者的语音缺陷, 这类方法存在一些问题, 如费时费力、给阅读障碍者带来阅读压力等。近年来, 大部分研究表明通过趣味性的动作视频游戏训练可以显著地提高发展性阅读障碍者的阅读技能, 但是其背后的机制尚不明确。基于大细胞通路缺陷理论框架, 从视觉空间注意、注意跨通道转换、视觉运动加工等方面来梳理动作视频游戏与阅读之间的关系, 揭示了动作视频游戏训练对阅读效率影响的可能内在机制。未来的研究可以在大细胞通路缺陷理论的框架下, 深入分析动作视频游戏改善阅读的神经机制, 并尝试开发更适合发展性阅读障碍者的干预程序。     

不患不均？容忍和支持经济不平等的心理学解释

不断加剧的经济不平等问题对个体和社会有着巨大危害,然而人们对经济不平等却有着较高的容忍性。基于个体心理的研究证据,本文提出认知和动机双重路径模型来解释个体容忍和支持经济不平等问题。在认知路径上,个体倾向于低估当前社会的经济不平等程度和将经济不平等评价为公平的;在动机路径上,个体预期经济不平等将带来自我利益的增加。未来研究应进一步整合多重心理机制间的关系,并探索有效干预手段以增加人们对减少经济不平等的支持。     

混合情绪能促进心理健康吗？

摘 要 积极和消极情绪的同时体验,即混合情绪,是生活中常见的情绪状态。健康应对的共激活模型、情绪动态模型和积极比模型一致认为混合情绪与心理健康之间呈现非线性的关系,适当的混合情绪有利于个体在困境中全面加工和整合信息,寻求意义,获得控制感,进而实现健康应对和心理症状改善,获得幸福感。未来研究应关注对非线性关系的精确描述;低压力或非压力情境下混合情绪的意义;进一步研究混合情绪促进心理健康的内部机制和影响因素。     

Emotional face recognition in autism and in cerebral visual impairments: In search for specificity

Autism spectrum disorder (ASD) is characterized by difficulties in the social domain, but also by hyper- and hypo-reactivity. Atypical visual behaviours and processing have often been observed. Nevertheless, several similar signs are also identified in other clinical conditions including cerebral visual impairments (CVI). In the present study, we investigated emotional face categorization in groups of children with ASD and CVI by comparing each group to typically developing individuals (TD) in two tasks. Stimuli were either non-filtered or filtered by low- and high-spatial frequencies (LSF and HSF). All participants completed the autism spectrum quotient score (AQ) and a complete neurovisual evaluation. The results show that while both clinical groups presented difficulties in the emotional face recognition tasks and atypical processing of filtered stimuli, they did not differ from one another. Additionally, autistic traits were observed in the CVI group and symmetrically, some visual disturbances were present in the ASD group as measured via the AQ score and a neurovisual evaluation, respectively. The present study suggests the relevance of comparing ASD to CVI by showing that emotional face categorization difficulties should not be solely considered as autism-specific but merit investigation for potential dysfunction of the visual processing neural network. These results are of interest in both clinical and research perspectives, indicating that systematic visual examination is warranted for individuals with ASD.     

Health Focused Psychotherapy In Treating a Dual Diagnosed Patient

Health-focused psychotherapy offers a contemporary model used in assessment, treatment planning and evaluation in addressing patients with both medical and psychiatric diagnoses. Clinicians in the health and mental health disciplines must know and understand the importance of standards of care and models of intervention and evaluation in clinical practice for this type of patient. Examined is the use of a specific model providing a tailored orientation to patient education, along with the development and use of a clinical algorithm and care pathway for clinical practice. Provided is a case study for applying the development and use of a clinical algorithm and care pathway for a dual diagnosed patient receiving health-focused psychotherapy.     

Dopamine regulation of human speech and bird song: a critical review

To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor control still remain open. One of them is the mechanism(s) by which neurotransmitters, such as dopamine, modulate speech and song production. In this review, we bring together the two fields of investigations of dopamine action on voice control in humans and songbirds, who share similar behavioral and neural mechanisms for speech and song production. While human studies investigating the role of dopamine in speech control are limited to reports in neurological patients, research on dopaminergic modulation of bird song control has recently expanded our views on how this system might be organized. We discuss the parallels between bird song and human speech from the perspective of dopaminergic control as well as outline important differences between these species.     

Pathways to flourishing among pharmacy students: The role of study demands and lecturer support

This study investigated possible pathways to flourishing among pharmacy students attending a South African university (N = 799; females = 81.6%; Afrikaans-speakers = 84.7%, mean age = 20.42 years, SD = 2.25 years). The students completed the Mental Health Continuum – Short Form (MHC-SF) and an Overload and Lecturer Support Survey. Of the 779 pharmacy students, 40.3% self-reported as flourishing, with high mean scores on workload and lecturer support. The level of emotional well-being of year group 2 was the highest. Following structural equation modelling, overload and lecturer support explained between 18% and 31% of the variance in the flourishing of the different year groups. From the second to the third year, the predictive value of overload and lecturer support for flourishing decreased by 8.8%. Lecturer support and low overload appear to play a positive role in the flourishing of higher education students.     

正强化和负强化:概念、争议与神经机制

1975年,Michael首次正式提出应放弃"正强化"和"负强化"术语的使用,引起对"正强化和负强化是否本质上具有区别"这一问题的关注和争议。正负强化究竟本质上是否有区分、如何区分、以及区分它们的意义等问题,得到了众多行为心理学家的深入探讨。多数学者再度阐明正强化和负强化具有不同的心理机制,加以区分具有重要应用意义,主张沿用对它们的区分。最近,对正负强化神经机制的研究取得突破性进展,进一步揭示它们具有截然不同的神经相关过程。我们建议,分析强化作用进行时,机体是否在环境条件作用下已经偏离了基础、正常的心理稳态,有助于规范理解强化物启动的是正还是负强化的神经过程。     

自闭症谱系障碍的生物基础

自闭症谱系障碍是一组发病于生命早期, 由一系列生理、心理因素引起的神经发育障碍。遗传、脑神经结构、营养素等是自闭症谱系障碍的生物基础的重要来源。个体在孕育早期形成的大脑和机体异常可能是导致自闭症谱系障碍的关键。这种异常在出生后的发育中具体作用于神经活动、脑发育、免疫系统等生理途径。研究者们今后可以尝试横跨不同自闭症谱系障碍亚型、年龄和发育阶段, 开展横向与纵向相结合的大范围研究, 以进一步明确自闭症谱系障碍的生物基础。
