聋人手语视觉表象生成能力的实验研究

通过视觉表象判断实验,对聋手语使用者和听力正常人两类被试视觉表象生成的能力进行了比较。实验发现：与听力正常的人相比,聋手语使用者学习和记忆大写字母的时间短于听力正常的被试,并且两组被试记忆复杂字母的时间都较长;聋被试和听力正常被试采用了相同的字母表征方式。但是,习得手语的年龄对聋手语者生成表象的能力没有明显的影响。     

依赖结构对信任行为的影响:基于互依理论的视角

信任是人际互动中的重要主题,受到诸多因素的影响,越来越多的研究者关注情境特征对信任的影响。以相互依赖理论为基础,操作依赖的相互性、依赖水平和利益协同,构建互动双方间不同的依赖结构,分析不同依赖结构对被试信任的影响。结果表明:(1)在双向依赖情境中被试的信任水平显著高于单向依赖情境;(2)单向依赖、低利益协同情境中,依赖水平对个体的信任行为有显著影响,双向依赖、高利益协同情境中,依赖水平对个体信任行为的影响不显著;(3)单向依赖、低依赖水平情境中,利益协同对信任行为有显著影响,双向依赖、高利益协同情境中,利益协同对信任行为影响不显著。     

Association between Child Abuse and Health Risk Behaviors among Chinese College Students

Little is known about the link between child abuse and health risk behaviors among Chinese college students. This cross-sectional study examined the prevalence of child abuse and its relations with individual and clusters of health risk behaviors among Chinese college students. A total of 507 students participated in this survey. The prevalence of child abuse from the highest to the lowest was emotional neglect (53.9%), physical neglect (49.0%), emotional abuse (21.8%), physical abuse (18.3%), and sexual abuse (18.1%), respectively. Males were more likely to report child abuse than females (p?<?0.01). For males, emotional abuse was associated with internet addiction [OR?=?2.28; 95%CI (1.00, 5.20)] and suicidal behavior [OR?=?12.47, 95%CI (2.61, 59.54)]; while sexual abuse was associated with internet addiction [OR?=?2.30, 95%CI (1.14, 4.66)]. For females, emotional abuse was significantly associated with increased risks for self-harm behavior [OR?=?15.03, 95%CI (3.59, 63.07)] and suicidal behavior [OR?=?5.16, 95%CI (1.63, 16.40)]. Physical abuse was related to risks for internet addiction [OR?=?2.50, 95%CI (1.03, 6.04)] significantly. Two-step cluster analysis showed that participants in clusters with more health risk behaviors reported higher scores of child abuse. These findings suggest that child abuse was associated with both individual and clustering of health risk behaviors among Chinese college students.     

双语者语言切换代价的影响因素

抑制控制、语言熟练度、任务相关因素和工作记忆容量是双语者语言切换代价的重要影响因素。其中,抑制控制抑或语言熟练程度何者主要调节着双语者的语言切换代价成为抑制控制模型和语言特异性选择模型争论的焦点。为此,未来研究需要在二语习得年龄与语言使用情景等因素是否影响双语者的控制机制、语言切换代价与任务转换代价的本质是否相同、语言切换代价和工作记忆之间的关系及其认知可塑性等领域予以进一步探索。     

Negative expectations and bad relationships: Effects of negative metastereotypes on doctor–patient relationships

This research aimed to examine the effects of negative metastereotypes (i.e., patients believe that doctors have negative opinions about them) and conflict experience on doctor–patient relationships. A 2 × 2 experimental study was conducted on 84 outpatients who were randomly assigned to either a negative metastereotype activation (NMSA) condition or a nonnegative metastereotype activation (non‐NMSA) condition. Each group consisted of patients with and without conflict experience (CE). Intergroup anxiety and doctor–patient relationships were subsequently assessed. Results showed that NMSA and CE increased intergroup anxiety and undermined doctor–patient relationships. In addition, the interaction between NMSA and CE on doctor–patient relationships was significant. When negative metastereotypes were activated, patients with CE showed more unfavorable relationships with doctors as compared with those under non‐NMSA activation condition; no metastereotype effects on doctor–patient relationships were observed among patients without CE. These findings provided insights into an important predictor of doctor–patient relationships as well as its mechanism. Future studies should consider negative metastereotypes and CE to develop interventions for improving doctor–patient relationships.     

Individual differences in motor development during early childhood: An MEG study

In a previous study, we reported the first measurements of pre‐movement and sensorimotor cortex activity in preschool age children (ages 3–5 years) using a customized pediatric magnetoencephalographic system. Movement‐related activity in the sensorimotor cortex differed from that typically observed in adults, suggesting that maturation of cortical motor networks was still incomplete by late preschool age. Here we compare these earlier results to a group of school age children (ages 6–8 years) including seven children from the original study measured again two years later, and a group of adults (mean age 31.1 years) performing the same task. Differences in movement‐related brain activity were observed both longitudinally within children in which repeated measurements were made, and cross‐sectionally between preschool age children, school age children, and adults. Movement‐related mu (8–12 Hz) and beta (15–30 Hz) oscillations demonstrated linear increases in amplitude and mean frequency with age. In contrast, movement‐evoked gamma synchronization demonstrated a step‐like transition from low (30–50 Hz) to high (70–90 Hz) narrow‐band oscillations, and this occurred at different ages in different children. Notably, pre‐movement activity (‘readiness fields’) observed in adults was absent in even the oldest children. These are the first direct observations of brain activity accompanying motor responses throughout early childhood, confirming that maturation of this activity is still incomplete by mid‐childhood. In addition, individual children demonstrated markedly different developmental trajectories in movement‐related brain activity, suggesting that individual differences need to be taken into account when studying motor development across age groups.     

字体、字号和词性对汉字认知加工的影响

实验采用2×7×3的混合实验设计,研究词性、字体和字号对汉字认知加工速度的影响。结果表明,词性对高频汉字的认知加工没有显著影响;在七种字体之中,宋体、正楷和黑体的加工速度较快,而行楷、隶书、魏碑和华文彩云的加工速度较慢,字体的主效应显著;字号的主效应虽然不显著,但24号字体和48号字体的加工速度显著快于36号字体。实验结果倾向于支持汉字识别的平行加工说。     

论汉魏六朝时期佛教的地狱思想

佛教地狱思想传入中国后,受到中国文化的影响,到南北朝时期基本完善并趋于复杂化.佛教的地狱思想具有内容丰富、系统复杂、传播迅速、影响巨大等特点,对中国人的宇宙观、世界观、人生观、生死观、道德观以及中国本土宗教、社会风俗等方面都产生了深刻的影响,并有力地推动了佛教在中国的传播.
