Both Earlier Times and the Future Are “Front”: The Distinction Between Time‐ and Ego‐Reference‐Points in Mandarin Speakers’ Temporal Representation

Mandarin speakers, like most other language speakers around the world, use spatial terms to talk about time. However, the direction of their mental temporal representation along the front‐back axis remains controversial because they use the spatial term “front” to refer to both earlier times (e.g., front‐year means “the year before last”) and the future (e.g., front‐road means “prospect”). Although the linguistic distinction between time‐ and ego‐reference‐point spatiotemporal metaphors in Mandarin suggests a promising clarification of the above controversy, there is little empirical evidence verifying this distinction. In this study, Mandarin speakers’ time‐ and ego‐reference‐point temporal representations on three axes (i.e., sagittal, lateral, and vertical) were separately examined through two tasks. In a time‐reference‐point task, Mandarin speakers judged whether the time point of the second picture was earlier or later than the time point of the first picture, while in an ego‐reference‐point task, they judged whether an event or phase had happened in the past or would happen in the future. The results indicate that Mandarin speakers construe an earlier‐times‐in‐front‐of‐later‐times temporal sequence and adopt the front‐to‐the‐future orientation.     

内隐人格观对他人知觉的影响

以大学生为被试,采用投射测验法分离出两类不同性质的内隐人格观,然后通过效价匹配实验和错觉关联实验,初步探讨了内隐人格观对他人知觉的信息加工模式的影响。研究结果表明:(1)跨性格、能力等不同人格属性有共通一致的内隐观;(2)固存观的反面就是渐变观,它们是同一维度的两极;(3)与渐变观者相比,固存观者更易以一种评价性方式知觉他人信息;同时,渐变观者不像固存观者那样对他人特质作出静态判断,而是集中注意力于理解他人行为发生的动态过程。     

Electrophysiological difference between the representations of causal judgment and associative judgment in semantic memory

Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources.     

宋代医官磨勘制度初探——兼论王安石思想对其影响

磨勘是宋代对于官员进行考核迁转的制度。但宋代初期在制定官员磨勘制度之时医官并未涵盖在内,并且医官的转任也有着相当的限制。北宋历次重大改革均将医学教育作为改革的重要内容,自此培养了大批医学人才,医官转任的限制也有逐渐放松的趋势。在王安石变法思潮的影响下,宋政府出于管理的需要,于熙宁年间正式确立医官磨勘制度。至宋徽宗重新启用变法派,于国子监设立中央医学,医官磨勘制度结合中央医学的设立有了进一步的细化和发展。虽然在制度的实施过程中由于管理不善出现过种种乱象,但医官磨勘制度对后世的医学发展有深远影响。

     

“快乐骨科”的起源、发展和临床实践

矫形外科治疗的病人都是肢体畸形残疾的弱势群体,多经历了艰难的求医过程,承载着肢体残障与尊严浩劫的心灵创伤。为了给肢体残疾者创造一个好的医疗环境,提出并建立了“快乐矫形骨科病区”,包括围手术期无痛病房、医患交流科普文化墙、定期举办医患联欢等。在不断实践中,提升了医生对生命的敬畏,对现代医术的驾驭和为病人解决问题的能力。在手术治疗复杂肢体畸形残疾近4 000例中,未发生1例大的医疗冲突事件,使矫形外科病房成为肢体残疾者恢复运动功能与心灵抚慰的康复乐园。     

口腔修复诊疗中人的审美形式感的产生

当前,医学美学作为技术美学涵盖下的一个分支,在口腔修复诊疗工作中,起着从未有过的重要作用。它以哲学的研究方法,运用艺术的手段,正自觉或不自觉地影响着口腔医护人员的工作。本文以口腔诊疗活动中形式美的审美为基点,讨论了几个有关的问题。     

认知诊断缺失数据处理方法的比较：零替换、多重插补与极大似然估计法

数据缺失在测验中经常发生, 认知诊断评估也不例外, 数据缺失会导致诊断结果的偏差。首先, 通过模拟研究在多种实验条件下比较了常用的缺失数据处理方法。结果表明：(1)缺失数据导致估计精确性下降, 随着人数与题目数量减少、缺失率增大、题目质量降低, 所有方法的PCCR均下降, Bias绝对值和RMSE均上升。(2)估计题目参数时, EM法表现最好, 其次是MI, FIML和ZR法表现不稳定。(3)估计被试知识状态时, EM和FIML表现最好, MI和ZR表现不稳定。其次, 在PISA2015实证数据中进一步探索了不同方法的表现。综合模拟和实证研究结果, 推荐选用EM或FIML法进行缺失数据处理。     

1993~2013年常驻高海拔地区军人心理健康状态的横断历史研究

研究为探索常驻高海拔地区军人心理健康水平如何随社会年代变迁而改变,运用了横断历史元分析的方法,对1993年至2013年38篇采用90项症状自评量表(SCL-90)的文献调查数据进行分析,考察了11454名常驻高海拔地区军人在该量表上9个因子得分随年代变化的趋势.结果发现:(1)SCL-90的7个因子均值与年代负相关,且不受期刊类型等的影响.20年来,7个因子下降了5%~15%不等.其中,强迫变化最大,抑郁、焦虑、人际敏感、偏执和精神病性均变化明显.这说明,常驻高海拔地区军人心理健康虽有所波动但整体水平逐步提升,变化幅度大致属于中等程度.(2)当年军费占GDP比值、居民消费水平指数与SCL-90部分因子均值负相关显著;5年前的居民消费水平指数与7个因子显著负相关.这说明,国防建设的经济投入和居民消费水平可能是影响常驻高海拔地区军人心理健康水平的重要因素.
