Positive emotion modulates cognitive control: An event‐related potentials study

There is substantial evidence to indicate that negative emotion can modulate cognitive control processing. However, only a few studies have investigated this effect with positive emotion. Therefore, the present study explored the electrophysiological correlates of the impact of positive emotional stimuli on cognitive control, using event‐related potentials (ERPs). Sixteen healthy young adults completed a modified Simon task (Simon, 1969). Behavioral data indicated that reaction times were faster for positive emotional stimuli than for neutral emotional stimuli in the incongruent condition, but not in the congruent condition, which suggested that positive emotion expedited conflict resolution. The ERP data showed that two negative ERP components (N300–400 and N450–550) were associated with the positive emotional stimuli in the incongruent minus congruent condition. It is suggested that these components may respectively be related to the conflict monitoring (N300–400) and response selection (N450–550) stages of cognitive control processing. Overall, our results indicated that positive emotion could facilitate cognitive control processing. These results are in line with the neuropsychological theory, according to which, positive emotion could modulate cognitive control mediated by increased dopamine levels in frontal brain areas.     

Re-Creation of Rituals in Humanistic Buddhism: A Case Study of FoGuangShan

The rise of humanistic Buddhism in the early twentieth century was a direct reaction against the practice of rituals for the dead by highlighting the importance of serving and benefiting the livings in this world here and now. Nevertheless, almost one hundred years later today, rituals for the dead continue to play very important role in Humanistic Buddhism. This paper analyses the ritual theory of Master Xing Yun (星雲), one of the leading figures in contemporary Humanistic Buddhism, and examines how Fo Guang Shan—founded by Xing Yu—has recreated rituals not only for the sake of the dead but also for the spiritual advancement of living human beings. I argue that (1) Humanistic Buddhism does not entirely reject rituals; (2) ritual practice in Humanistic Buddhism has maintained the idea of transcendence of Buddhism, thus actually sanctifying the secular life of Buddhists and extending the sacred space to the public arena beyond the temple walls.     

Neural correlates of feigned memory impairment are distinguishable from answering randomly and answering incorrectly: an fMRI and behavioral study

Previous functional magnetic resonance imaging (fMRI) studies have identified activation in the prefrontal-parietal-sub-cortical circuit during feigned memory impairment when comparing with truthful telling. Here, we used fMRI to determine whether neural activity can differentiate between answering correctly, answering randomly, answering incorrectly, and feigned memory impairment. In this study, 12 healthy subjects underwent block-design fMRI while they performed digit task of forced-choice format under four conditions: answering correctly, answering randomly, answering incorrectly, and simulated feigned memory impairment. There were three main results. First, six areas, including the left prefrontal cortex, the left superior temporal lobe, the right postcentral gyrus, the right superior parietal cortex, the right superior occipital cortex, and the right putamen, were significantly modulated by condition type. Second, for some areas, including the right superior parietal cortex, the right postcentral gyrus, the right superior occipital cortex, and the right putamen, brain activity was significantly greater in feigned memory impairment than answering randomly. Third, for the areas including the left prefrontal cortex and the right putamen, brain activity was significantly greater in feigned memory impairment than answering incorrectly. In contrast, for the left superior temporal lobe, brain activity was significantly greater in answering incorrectly than feigned memory impairment. The results suggest that neural correlates of feigned memory impairment are distinguishable from answering randomly and answering incorrectly in healthy subjects.     

心理治疗两种范式的对立及其整合

心理治疗有两种不同的范式:科学主义治疗范式和人文主义治疗范式。前者主要由行为疗法和认知—行为疗法的诸种治疗形式所构成;后者则包括当事人中心疗法、存在疗法等。两种范式在人性观、心理诊断、治疗关系、治疗方法和治疗目的等方面存在着明显的对立。对此进行分析,并提出两者整合的构思,以期裨益于心理治疗实践。     

社会阶层与大学生网络利他行为:一个有调节的中介模型

采用问卷法对813名大学生进行调查,探讨社会阶层、公正世界信念、网络社会支持与大学生网络利他行为之间的关系及内在作用机制。结果发现：（1）客观社会阶层不能显著预测网络利他行为,主观社会阶层能正向预测网络利他行为;（2）公正世界信念在主观社会阶层与网络利他行为的关系中起部分中介作用;（3）网络社会支持调节了公正世界信念的中介作用。对于高网络社会支持个体,公正世界信念起部分中介作用;而对于低网络社会支持个体,公正世界信念的中介效应不显著,主观社会阶层对网络利他行为只有直接效应。     

循证医学时代安慰剂的再认识

安慰剂的治疗作用早已被人们认识,但是对于其在医学上的应用却一直存在争议。在循证医学兴起的今天,我们应该如何辩证地看待安慰剂的作用及不足,以及在临床试验中应该如何应用安慰剂是一个值得探讨的问题。     

大学生问题发现过程的问题行为图研究

在潜藏式与矛盾式情境两类问题发现任务中,采用出声思维的方法研究问题发现能力高与低两类各10名大学生问题发现过程的内部认知活动。利用问题行为图技术进行个案分析,着重考察大学生在知识状态、思维操作及问题行为图等方面的表现。基于加工性质把知识编码为陈述性、程序性和策略性知识;基于信息来源编码为情境、内部和推断信息;基于思维关联与转换,把思维操作编码为独立、横向、纵向与元认知思维。研究表明:(1)问题发现中,在内部信息、纵向思维以及纵横交错型行为图的使用频次上,潜藏情境高于矛盾情境;在情境信息、横向思维以及横向平行和横向归纳型行为图的使用频次上,矛盾情境高于潜藏情境。(2)高低能力组被试在知识状态、思维操作与问题行为图的使用上差异均不显著,可能是由于上述方面涉及问题发现的基本认知过程和思维规律,具有普遍性特征。
