大学生网络同一性实验与自我同一性的关系:网络社交倾向和强迫性网络使用的作用

从网络同一性实验与自我同一性间关系的分歧出发,提出相应的理论模型,考察网络社交倾向的调节作用及强迫性网络使用的中介作用。本研究采用网络同一性实验量表、自我同一性实验问卷以及强迫性网络使用量表对275名大学生进行了测量,结果表明:(1)网络社交倾向对网络同一性实验与自我同一性的关系具有调节作用。对于线下社交倾向的大学生,网络同一性实验对自我同一性有消极预测作用;但对于线上社交倾向的大学生,中等程度的网络同一性实验会积极预测自我同一性的发展;(2)强迫性网络使用在网络同一性实验与自我同一性的关系中起完全中介作用。总之,网络同一性实验整体上不利于大学生自我同一性的发展,但若把握好"度"也可以发挥其积极作用。     

Is Disciplinary Culture a Moderator Between Materialism and Subjective Well-being? A Three-Wave Longitudinal Study

To clarify the influence of disciplinary culture on the materialism–subjective well-being (SWB) relationship, as well as the relationship between changes in materialism and changes in SWB, the current longitudinal study tracked the levels of materialism and SWB among first-year undergraduates for 12 months. A total of 218 participants from a congruent disciplinary culture (i.e., business school) and 210 participants from an incongruent disciplinary culture (i.e., engineering school) provided ratings on the Material Values Scale, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule in three waves. The following results were obtained: (1) the interaction effect of disciplinary culture and time was significant. In Wave 3, the level of materialism in business school was significantly higher than that in engineering school, but this difference was not found in Waves 1 and 2; (2) the negative relationship between materialism and SWB remained stable over time and was not moderated by disciplinary culture. Moreover, disciplinary culture did not moderate the relationship between changes in materialism and changes in SWB. The above findings indicate that disciplinary culture influences the development of materialism but not the materialism–SWB relationship in the long term.     

Applying Western models of volunteering in Hong Kong: The role of empathy,prosocial motivation and motive–experience fit for volunteering

The present research investigates the applicability of prominent Western volunteering frameworks in Hong Kong. Two cross‐sectional surveys involving a total of 268 respondents were conducted. In Study 1, we tested a model of volunteering among 149 Hong Kong Chinese adult individuals (M_age = 34.8 years; 51.7% female) that examines antecedents and outcomes of voluntary engagement. Results show that prosocial motivation relates to volunteering, and that volunteering in turn predicts life satisfaction. Unexpectedly, and unlike studies in Western settings, other‐oriented empathy was not related to volunteering. Study 2 tests the propositions of the Volunteer Process Model (VPM) among 119 Hong Kong Chinese volunteers (M_age = 36.9 years; 58.0% female). Findings largely support the VPM: our results indicate that the link between motives, voluntary service length and frequency is mediated by satisfaction with volunteering. Moreover, findings suggest that a fit between motives and experience seems relevant for increasing volunteers' satisfaction with their service. Results of both studies suggest that Western volunteering models can be applied to volunteering in East Asian cultures when culture‐specific adaptations are considered.     

Shyness and Adaptation to School in a Chinese Community

This study examined the process of adjustment in shy and nonshy children during the transition to school in a Chinese community. Children (35 shy and 19 nonshy) were assessed three times before and after they entered the first grade. Shy and nonshy children's interactions with peers and teachers, perceived peer acceptance, and anxious behaviour were measured using multiple methods, including naturalistic observations, self‐report, and teacher report. Results indicated that shy and nonshy children showed consistently different behavioural profiles in free play settings and structured classes during the transition. However, teacher ratings of and peer responses to shy and nonshy children were not consistently different. Results are discussed in relation to the cultural context where the study was conducted.

Multitasking versus multiplexing: Toward a normative account of limitations in the simultaneous execution of control-demanding behaviors

Why is it that behaviors that rely on control, so striking in their diversity and flexibility, are also subject to such striking limitations? Typically, people cannot engage in more than a few—and usually only a single—control-demanding task at a time. This limitation was a defining element in the earliest conceptualizations of controlled processing; it remains one of the most widely accepted axioms of cognitive psychology, and is even the basis for some laws (e.g., against the use of mobile devices while driving). Remarkably, however, the source of this limitation is still not understood. Here, we examine one potential source of this limitation, in terms of a trade-off between the flexibility and efficiency of representation (“multiplexing”) and the simultaneous engagement of different processing pathways (“multitasking”). We show that even a modest amount of multiplexing rapidly introduces cross-talk among processing pathways, thereby constraining the number that can be productively engaged at once. We propose that, given the large number of advantages of efficient coding, the human brain has favored this over the capacity for multitasking of control-demanding processes.     

基于文本阅读的间接接触也可改善公众对残疾人的态度

以镶嵌残疾人图片的正性行为描述性信息为文本阅读材料,以大学生为被试,采用概念启动范式,考察了健全人对残疾人态度改善的可能性.研究结果表明,阅读残疾人正性行为描述性材料不仅可以降低健全人对残疾人的负性认知评价,而且可以提高其对残疾人的钦佩感和减弱其对残疾人的嫌弃感,同时也可提高健全人对该类人群的积极趋近行为和减弱对该类人群的消极趋近和消极回避行为,从而证明基于文本阅读的间接接触可改善公众对残疾人的负性态度的假设.因此,创造条件鼓励残疾人尽力发挥其积极的社会功能,引导和塑造其身残志不残的品质,有助于改善健全人对该类人群的消极态度.     

The influence of spatial pattern on visual short-term memory for contrast

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not decrease significantly, even for memory intervals of up to 30 s. For other properties, such as stimulus orientation and contrast, however, such “perfect storage” behavior is not found, although the reasons for this difference remain unresolved. Here, we report two experiments in which we investigated the nature of the representation of stimulus contrast in VSTM using spatially complex, two-dimensional random-noise stimuli. We addressed whether information about contrast per se is retained during the memory interval by using a test stimulus with the same spatial structure but either the same or the opposite local contrast polarity, with respect to the comparison (i.e., remembered) stimulus. We found that discrimination thresholds got steadily worse with increasing duration of the memory interval. Furthermore, performance was better when the test and comparison stimuli had the same local contrast polarity than when they were contrast-reversed. Finally, when a noise mask was introduced during the memory interval, its disruptive effect was maximal when the spatial configuration of its constituent elements was uncorrelated with those of the comparison and test stimuli. These results suggest that VSTM for contrast is closely tied to the spatial configuration of stimuli and is not transformed into a more abstract representation.     

A Comparison on Inclusive Practices for Children with Special Needs in Faith-Based Kindergartens in Hong Kong

This qualitative study aimed to examine the inclusive practices implemented in three faith-based kindergartens in Hong Kong. A questionnaire was used to collect information about school backgrounds, students’ special needs, teacher training, special education services, curriculum design, school policy, parental involvement, and challenges faced by these schools when implementing their inclusive practices. The primary focus of this study was the influence of faiths on the provision of inclusive services for children with special needs. The results indicated that faiths, along with other factors, have played a significant role in contributing to the inclusive education services provided to children in these schools.     

右美托咪定对甲亢患者术中血流动力学的比较研究

研究右美托咪定辅助甲亢患者麻醉诱导时血流动力学的改变。40例甲亢患者,随机分为两组：右美托咪定组（ n＝20）与对照组（n＝20）。记录术前与麻醉诱导后的血压、心率、心率收缩压乘积,抽取静脉血进行儿茶酚胺检测。结果右美托咪定组诱导后、插管后即刻、1分钟、2分钟、3分钟,血压、心率、心率收缩压乘积低于对照组,差异有统计学意义（P＜0．05）。右美托咪定组儿茶酚胺在插管后1分钟、插管后2分钟、插管后3分钟低于对照组差异有统计学意义（P＜0．05）。右美托咪定有利于维持甲亢患者麻醉诱导中血流动力学的稳定。
