Cognitive neuroscience in China

In the last decade, cognitive neuroscience in China has advanced in at least four aspects: first, specialized research institutes and bodies have been set up throughout the nation; second, more and more high‐tech research facilities and approaches have been adopted by domestic researchers; third, international conferences on cognitive neuroscience have been held in Mainland China; and finally, publications relating cognitive processes to neural activation and functioning have increased. This paper selectively reviews research on perception and face recognition, attention, language, memory, and disorders in cognitive brain functions carried out by scientists in Mainland China. For visual perception, some excellent work has been carried out to investigate the neural mechanisms of perceptual priming, perceptual grouping, and perception of global/local properties in compound stimuli. For attention, much work is on issues such as the time course of brain activation in selective attention, the patterns of event‐related potentials in visual and auditory selective attention, and the effect of pre‐cueing on spatial attention. Because the Chinese language has many unique characteristics in phonological and syntactic systems and in the writing system, much research carried out in China takes advantage of these characteristics, trying to separate the universal and language‐specific aspects of language processing and their neural correlates. Memory research is mainly at neuropsychological and neurobiological levels. Disorders of cognitive functioning and their underlying impairments in the brain are attracting more and more attention. The paper concludes that as the Chinese economy is growing fast, more resources will be poured into basic research. Thus, systematic research in various fields of cognitive neuroscience by Chinese scientists is no longer a dream. It is reasonable to expect that research in this field will be accelerated in China and become an important force in the world in the near future.     

患者的依从性在环形医患关系模型中的作用

2006年,美国的Williams等人提出环形医患关系模型.从患者的角度出发,研究临床依从性在环形医患关系中的作用.加强医惠交流、改善医患接触质量可以提高患者的依从性;反过来,患者对治疗的依从会促进环形关系良性运转.医生的心理健康水平和患者的依从性是医患关系互动中对两个不同主体的各自要求.     

Socio-Demographic Correlates of Fear of Crime and the Social Context of Contemporary Urban China

Previous research in the West has established major socio-demographic correlates of fear of crime. The interpretation of these correlates is typically based on the concept of physical or social vulnerability of individuals. These correlates are implicitly regarded as invariant to social or community contexts, reflecting universal human behavioral patterns. The present study argues that social change may alter patterns of perceptions associated with fear among socio-demographic groups, thus affecting socio-demographic correlates of fear of crime. We explore how social changes in China have created a generational gap that influences the effects of age and education on fear of crime. The study finds that, in contrast with the well-established patterns in Western communities, the young and educated exhibit a higher level of fear of crime in urban China than their counterparts. The study also finds that consistent with Western literature, females are fearful and that personal victimization experience increases the level of fear. We discuss the social and community processes that produce these interesting patterns.

中小学生正念注意觉知与心理健康：情绪调节和积极重评的跨时间中介作用

本研究探讨中小学生正念注意觉知的发展及其与心理健康的关系,并考察情绪调节和积极重评在其中起到的中介作用。研究采用追踪设计,来自江西地区两所小学(4到6年级)和两所中学(7到9年级)的共1251名学生(男生691人,女生560人)在间隔半年的两个时间点分别填写了测量正念注意觉知、心理健康(生活满意度、抑郁、焦虑、学业压力)、情绪调节以及积极重评的问卷。结果表明：(1)中学生正念注意觉知显著低于小学生;(2)中小学生正念注意觉知与两个时间点的情绪调节、积极重评及心理健康均显著相关;(3)跨时间点中介效应检验结果表明,在中小学生正念注意觉知和各心理健康变量的关系中,情绪调节中介效应均显著,积极重评中介效应均不显著。结论：中小学生正念注意觉知与心理健康密切相关,正念注意觉知通过情绪调节能力间接作用于中小学生心理健康。

铁钦纳的存在主义

铁钦纳(E.B.Titchener 1867—1927)自称他的心理学为存在主义的。铁钦纳把他的心理学与当时美国的机能主义心理学相对立。西方心理学界一般称铁钦纳的心理学为构造主义。 铁钦纳认为心理学的问题,如其他自然科学一样,是:什么?怎样?和为什么?三个问题。心理学的什么,是将心理现象分析为它的元素;心理学的怎样,是寻求这些元素如何互相联系的规律;心理学的为什么,是以一个心理过程相应的神经过程来解释这     

The role of dark pattern stimuli and personality in online impulse shopping: An application of S-O-R theory

Online impulse shopping is a growing industry. This paper uses the Stimulus-Organism-Response framework to model online impulse purchase behavior using a novel combination of stimuli and organism characteristics. The stimuli: social proof, limited-quantity scarcity, and high-demand, are three commonly used website features known as dark patterns. The organism characteristic personality is measured by the big 5 personality traits and persona generated through latent profile analysis. Using the machine learning algorithm XGBoost, impulse purchasing response was predicted separately for each dark pattern stimuli. Results show personality characteristics are important features when predicting consumer impulse purchasing in response to dark pattern messages. Moreover, the personality traits (and personas) most predictive of impulse shopping behavior varied by type of dark pattern. Findings suggest personality influences susceptibility to different dark patterns, indicating a need for tailored interventions to mitigate individual consumer vulnerabilities to impulse shopping.     

The precision of velocity discrimination across spatial frequency

The precision of velocity coding for moving stimuli of different spatial frequencies was assessed by measuring velocity discrimination thresholds for a 1-c/deg grating paired with a grating whose spatial frequency ranged from 0.25 to 4 c/deg and for grating pairs of the same spatial frequency (0.25, 1, and 4 c/deg). The gratings always moved upward, with velocities ranging from 0.5 to 16 deg/sec, Velocity discrimination was as precise for stimuli that varied in spatial frequency by: ±2 octaves (0.25 vs. 1 c/deg and 4 vs. 1 c/deg) as for stimuli of the same spatial frequency, for specific ranges of velocity that depended on the spatial and, therefore, the temporal frequencies of the stimuli. Compared with a 1-c/deg grating, the perceived velocity of 4-c/deg gratings was about 1.3 times faster and that of 0.25-c/deg gratings was about 1.3 times slower. Although these perceived velocity biases imply variation of velocity-signal processing among spatial frequency channels, the discrimination results indicate that the motion-sensing system can compare signals across different spatial frequency channels to make fine velocity discrimination within appropriate temporal frequency limits.     

An intensional epistemic logic

One of the fundamental properties inclassical equational reasoning isLeibniz's principle of substitution. Unfortunately, this propertydoes not hold instandard epistemic logic. Furthermore,Herbrand's lifting theorem which isessential to thecompleteness ofresolution andParamodulation in theclassical first order logic (FOL), turns out to be invalid in standard epistemic logic. In particular, unlike classical logic, there is no skolemization normal form for standard epistemic logic. To solve these problems, we introduce anintensional epistemic logic, based on avariation of Kripke's possible-worlds semantics that need not have a constant domain. We show how a weaker notion of substitution through indexed terms can retain the Herbrand theorem. We prove how the logic can yield a satisfibility preserving skolemization form. In particular, we present an intensional principle for unifing indexed terms. Finally, we describe asound andcomplete inference system for a Horn subset of the logic withequality, based onepistemic SLD-resolution.
