对交迭任务记忆的实验研究(Ⅱ)

对交迭记忆任务的实验室模拟实验结果表明:(1)任务交迭类型、交迭任务数和任务呈现间隔时间都是影响交迭记忆业绩的因素。交迭记忆业绩随任务交迭类型的复杂程度提高而降低,随呈现间隔时间的延长而提高;在复式交迭类型中,随交迭任务数的增多而降低。从而说明了时间繁忙和信息加工强度是心理负荷的两个因素。(2)据实验结果求出了在本实验情境下的交迭记忆曲线公式。     

双目光学测距仪器光轴不平行度范围的实验研究

目前,我国的双目光学测距仪器光轴不平行度公差大致有以下几组: 垂直发散:±15′±20′±20′±27′ 水平发散:60′60′60′60′ 水平会聚:20′20′30′36′上述数据基本上是沿袭国外有关数据。美苏两国这方面的数据大致为:     

对交替呈现的立体图对的双眼立体视觉的探讨

本实验用APPLE Ⅱ微机控制的同视机,选用医用三级检查图片中的彩色和黑白两种立体图对,对30名被试进行实验。结果表明:(1)在同视机条件下,当双眼图象交替闪烁相位的交替频率平均在7Hz以上时,双眼立体视觉形成。(2)双眼刺激交替呈现时,彩色图对的立体感闪烁融合阈值约为33Hz,黑白图对的立体感闪烁融合阈值约为25Hz,两者差异十分显著(P<0.0001)。     

先苦后乐:英语乐学大学生在英语学习时情绪反应的脑认知特点

运用功能性磁共振成像(fMRI)技术探索了乐学英语的大学生在对中、英文材料的学习、记忆及成绩反馈过程中的情绪和脑活动特征。结果发现,被试学习英文较之学习中文积极情绪更少且伴随更强的前部脑岛的激活;但当他们获得关于英文成绩的正反馈时,中脑奖赏区的激活却明显高于获得中文成绩正反馈时的情形,且中脑激活与英语乐学呈正相关。这说明乐学是"苦中作乐",人们虽在学习时并未体验到更多快乐,但其成功却带来了更大的心理奖赏。     

江苏省公立医院医务人员工作满意度评价及调查分析

采用问卷调查和深入访谈,评价及分析江苏省公立医院医务人员的工作满意度。问卷调查包括薪酬福利、发展晋升、工作内容与工作环境、上下级关系、同级同事关系5个维度。结合调查结果,对参与问卷调查的某省级三甲医院的医务人员进行深入访谈。江苏省公立医院医务人员工作满意度低于全国水平的原因集中在职业风险高、工作负担重、晋升机会少等方面。为充分调动医务人员的工作积极性,应该建立公平的薪酬补偿机制,增强医务人员的组织凝聚力。     

Bayesian analysis of mixtures in structural equation models with non‐ignorable missing data

Structural equation models (SEMs) have become widely used to determine the interrelationships between latent and observed variables in social, psychological, and behavioural sciences. As heterogeneous data are very common in practical research in these fields, the analysis of mixture models has received a lot of attention in the literature. An important issue in the analysis of mixture SEMs is the presence of missing data, in particular of data missing with a non‐ignorable mechanism. However, only a limited amount of work has been done in analysing mixture SEMs with non‐ignorable missing data. The main objective of this paper is to develop a Bayesian approach for analysing mixture SEMs with an unknown number of components and non‐ignorable missing data. A simulation study shows that Bayesian estimates obtained by the proposed Markov chain Monte Carlo methods are accurate and the Bayes factor computed via a path sampling procedure is useful for identifying the correct number of components, selecting an appropriate missingness mechanism, and investigating various effects of latent variables in the mixture SEMs. A real data set on a study of job satisfaction is used to demonstrate the methodology.

腹腔镜在女性盆底修复术中的应用

随着社会老龄化的加剧,盆底功能障碍性疾病的发病率日益上升.之前热门的盆底重建术随着时间的推移,并发症相继出现.美国食品药品管理局(FDA)连续两次发布了关于经阴道网片的警告,使专家们认识到了问题的严重性.经过30余年的发展,腹腔镜技术已经被广泛地应用于各类妇科手术中.腹腔镜在女性盆底修复术中的应用重新得到了关注.自1991年腹腔镜技术首次应用于女性盆底修复手术中以来,国内外不断有新的腹腔镜下盆底修复术式的报道.现就各种腹腔镜下盆底修复手术做一综述.     

Intuitive Conceptions of Dead Persons' Mentality: A Cross-Cultural Replication and More

Jesse Bering (2002) investigated how American university students in an interview task conceived of dead persons' mentality immediately after death. He found that different categories of mental states or capacities were conceived differently: psychobiological and perceptual states ceased, whereas emotional, desire, and epistemic states continued. Our Study 1 was a replication of Bering's experiment in a different cultural setting, in which the subjects were Chinese undergraduate students. A similar pattern of results was found. In Study 2, instead of being asked about a dead person's various mental states immediately following the death, participants were asked to judge a dead person's mental states after the person had been dead for 2 days. The overall pattern of participants' responses was not affected by this manipulation, but they did show an increase in attributions of certain mental states to dead agnostics. In addition, a more refined breakdown of responses revealed that individuals tended to judge that, upon death, visual and auditory perception continued, whereas olfactory and gustatory sensation ceased.     

The development of social value orientation across different contexts

This study aimed to explore Chinese children's social value orientation across different ages and contexts. Revised decomposed games were used to measure the social value orientation of 9‐, 11‐, and 14‐year‐old children and college students as an adult group. About half of them were assigned to the hypothetical context of “equal payment group,” providing equal compensation for participation in the study, and the others to the “real payment group,” who got payment according to their own choices in the games. Results showed that 9‐ and 11‐year‐old children's choices differed between the two contexts: They made more prosocial choices in the hypothetical context, and more competitive choices in the “real payment” context. The 14‐year‐olds’ and adults’ choices were not significantly different in the two contexts. These results may imply that by 14 years of age, children have stable social value orientation, and their behavior reflects this value.
