西医东渐及其与中医的碰撞

在西医东渐过程中,中西两种医学的相遇及其关系涉及到社会、思想、文化因素.考察历史的过程中重点关注民国时期的"废止中医案",认为当前关于中医存废的争论是历史问题的延续,在很大程度上,中西医论争是外部因素推动的结果,而非根源于医疗实践.最终将中西医争论的问题引入到医学自身的进步上去.     

论进化心理学的“心理机制”

“心理机制”是进化心理学的核心概念。对这一概念的理解直接影响着对整个进化心理学理论的理解。该文尝试从心理学其它相关学科的角度,对这一概念的性质进行充分的解读与分析,同时也指出进化心理学“心理机制”理论之明显误区,并在此基础上对进化心理学价值之所在给予充分的彰显。     

Personality differences between online game players and nonplayers in a student sample.

This study examines the differences in openness, conscientiousness, and extraversion between online game players and nonplayers using a student sample. The matched sample comprised 130 pairs of students, who are paired in gender and age. The results indicate that online game players reported higher scores in openness, conscientiousness, and extraversion than did nonplayers.     

Is the History of our Universe Finite?

Modern cosmology indicates that our universe has a finite age. However, it is not understood whether the initial state before the Big Bang is finite in history or not. In this article, I show by simple arguments that the initial state must be finite in history if it is real. If the initial state is not real, a special transition is needed to specify the beginning of the real time. Moreover, if our universe is just one of the many universes, it can be shown that the history of the universe generator must also be finite.     

Validation of the Preschool Anxiety Scale-Traditional Chinese (PAS-TC) in Hong Kong

Anxiety disorders are the most common type of psychiatric conditions in children. Early identification and intervention during preschool years is critical for minimizing their detrimental long-term effects. The Preschool Anxiety Scale (PAS) is a developmentally-sensitive and symptom-specific instrument that has been commonly used and widely validated in the west. The current study tested the psychometric properties of its Traditional Chinese version (PAS-TC) in Hong Kong. The study sample consisted of a total of 1317 Hong Kong parents, recruited from 12 local preschools, with preschool children aged from three to six years old. Results showed that a correlated five-factor model demonstrated a good fit for the data. PAS-TC also demonstrated acceptable reliability and satisfactory validity. Furthermore, gender but not age effects were found in Hong Kong. Additionally, similar to previous studies, items from physical injury fears were the most reported in the top-ten frequently endorsed items. Finally, the anxiety level of our Hong Kong sample was found to be between the Mainland China and western countries. Clinical implications of the above findings concerning PAS-TC are discussed.

     

Body Surveillance Predicts Men’s and Women’s Perceived Loneliness: A Serial Mediation Model

Previous research on self-objectification mainly focuses on its influences on intrapersonal psychological distress whereas our study examined whether self-objectification would influence interpersonal distress (i.e., loneliness) and its corresponding mechanisms in a sample of American women and men recruited with MTurk. Participants’ self-objectification was indexed by their level of body surveillance, and we proposed that body surveillance would increase women’s and men’s tendency to experience shame about their body and decrease their general self-esteem, which would in turn predict their level of loneliness. A total of 373 Americans (235 women; Mdn_age?=?33 years-old, range?=?18–77) participated in the present study, and the results provided support for the proposed theoretical model. Specifically, we found that body surveillance positively predicted people’s body shame, and body shame negatively predicted self-esteem, which in turn predicted people’s loneliness. Moreover, this mediational model was not different between men and women. These results expand the scope of investigation by incorporating male samples, and they suggest that in addition to intrapersonal consequences, self-objectification can also influence people’s interpersonal well-being. Implications were discussed.

     

How to know and choose online games: differences between current and potential players.

This study investigated how different adolescent players acquire game information and the criteria they use in choosing online games and found that (1) current players generally use comprehensive information sources more than potential players do; (2) current players rely on free trials and smooth display of motion graphics as choice criteria more than potential players do; (3) potential players rely on the look of advertisements more than current players do; (4) both current and potential players most likely use word-of-mouth and gaming programs on TV as information sources; and (5) endorser attractiveness is ranked the least important among six choice criteria by both current and potential players.     

Designing time-limited cyber promotions: effects of time limit and involvement.

This study found that a longer time limit in cyber promotions results in lower time pressure perceptions by consumers and a greater rate of consumers choosing higher-priced items. Furthermore, products with which consumers are more involved entail higher time pressure, lower consumer satisfaction, and a lower share of consumers using the promotion for that product.     

Inaccurate representation of the ground surface beyond a texture boundary

The sequential-surface-integration-process (SSIP) hypothesis was proposed to elucidate how the visual system constructs the ground-surface representation in the intermediate distance range (He et al, 2004 Perception 33 789-806). According to the hypothesis, the SSIP constructs an accurate representation of the near ground surface by using reliable near depth cues. The near ground representation then serves as a template for integrating the adjacent surface patch by using the texture gradient information as the predominant depth cue. By sequentially integrating the surface patches from near to far, the visual system obtains the global ground representation. A critical prediction of the SSIP hypothesis is that, when an abrupt texture-gradient change exists between the near and far ground surfaces, the SSIP can no longer accurately represent the far surface. Consequently, the representation of the far surface will be slanted upward toward the frontoparallel plane (owing to the intrinsic bias of the visual system), and the egocentric distance of a target on the far surface will be underestimated. Our previous findings in the real 3-D environment have shown that observers underestimated the target distance across a texture boundary. Here, we used the virtual-reality system to first test distance judgments with a distance-matching task. We created the texture boundary by having virtual grass- and cobblestone-textured patterns abutting on a flat (horizontal) ground surface in experiment 1, and by placing a brick wall to interrupt the continuous texture gradient of a flat grass surface in experiment 2. In both instances, observers underestimated the target distance across the texture boundary, compared to the homogeneous-texture ground surface (control). Second, we tested the proposal that the far surface beyond the texture boundary is perceived as slanted upward. For this, we used a virtual checkerboard-textured ground surface that was interrupted by a texture boundary. We found that not only was the target distance beyond the texture boundary underestimated relative to the homogeneous-texture condition, but the far surface beyond the texture boundary was also perceived as relatively slanted upward (experiment 3). Altogether, our results confirm the predictions of the SSIP hypothesis.     

Does Social Protest Shake People’s Justice Beliefs? It Depends on the Level of Group Identification

We examined whether social protests will shake people's justice belief, and its potential mechanisms. Participants were reminded of an occurrence of a social protest (vs. an ordinary event) and their justice belief toward social system as well as attitudes toward the protest was measured. Moreover, participants’ perceived group identification with the protesters was measured in Experiment 1 and manipulated in Experiment 2. The results revealed that participants with greater group identification perceived the social system as more just, and were less supportive of the protest than those with low group identification. The implications of these findings were discussed.
