9970名中学生心理素质的研究

对北京市随机抽取的９９７０名中学生进行自编的《中学生心理素质测验》的测试,结果表明：（１）总体而言,中学生的心理素质水平良好。（２）年级越低,心理素质水平越高,年级越高,心理素质水平越低。（３）初中生的心理素质水平好于高中生。（４）在男女性别差异上,年级越低,男女差异越大,年级越高,差异越小。其中,男生在智力和情绪因子上心理素质水平好于女生,女生在注意力和道德感因子上心理素质水平好于男生。在对初中与高中的男女性别考验中也得到了一致的结论。     

中国人眼光谱相对视亮度函数的研究——Ⅲ.不同大小视野对V(λ)的影响

本实验采用闪烁光度法。本实验的视野是7°40′和20′,受试者5人,均属色觉正常者。年龄在30至50岁之间,具有一定实验经验。实验波长从420—700nm,其间隔为20nm,实验的亮度级为30cd/m~2。 四种视野相比较,其中2°视野V(λ)曲线引自明视函数,10°视角的材料来自CIE1964年补充标准观察者?10(λ),其结果:峰值的短波一侧随着视野的增加V(λ)值显著增加,而在峰值的长波一侧则无显著变化。     

亮度对白光和色光临界融合频率的影响

本实验研究了不同亮度级的光谱色光(440,460,540,560,640,660nm)和白光的CFF。结果表明:除极高亮度(5087td)外,CFF与logI函数均呈线性关系。白光表现了最大的CFF,其图线斜率大于任何色光的图线斜率。可以见到:亮度是CFF和logI之间关系的最重要的决定因素之一。在所用的色光中,绿色不论在CFF绝对值或其图线斜率方面均高于光谱两端色光的相应数据。从而可以推断:波长对CFF和logI之间关系的效应不可忽视。光谱两端色光曲线的差别明显,而同色区内相邻色的曲线间差异则不显著,这又一次说明波长的区别对CFF的意义重大。在某些亮度水平上白光CFF绝对值低于色光,虽然在最高亮度级时其最大CFF值高于所有色光的相应数据。我们的研究结果再次提出,有必要对CIE V(λ)在某些条件下应用的适当性进行重新考虑。     

Perceptual organization of apparent motion in the Ternus display

A typical Ternus display has three sequentially presented frames, in which frame 1 consists of three motion tokens, frame 2 (blank) defines the interstimulus interval, and frame 3 has similar motion tokens with their relative positions shifted to the right. Interestingly, what appears to be a seemingly simple arrangement of stimuli can induce one of two distinct apparent-motion percepts in the observer. The first is an element-motion perception where the left-end token is seen to jump over its two neighboring tokens (inner tokens) to the right end of the display. The second is a group-motion perception where the entire display of the three tokens is seen to move to the right. How does the visual system choose between these two apparent-motion perceptions? It is hypothesized that the choice of motion perception is determined in part by the perceptual organization of the motion tokens. Specifically, a group-motion perception is experienced when a strong grouping tendency exists among the motion tokens belonging to the same frame. Conversely, an element-motion perception is experienced when a strong grouping tendency exists between the inner motion tokens in frames 1 and 3 (i.e. the two tokens that overlap in space between frames). We tested this hypothesis by varying the perceptual organization of the motion tokens. Both spatial (form similarity, 3-D proximity, common surface/common region, and occlusion) and temporal (motion priming) factors of perceptual organization were tested. We found that the apparent-motion perception of the Ternus display can be predictably affected, in a manner consistent with the perceptual organization hypothesis.     

脑外伤患者记忆功能的双重特征：损伤与保存

该研究探讨了中─重型闭合性脑外伤患者及对照被试（各１７名）在对单个汉字不同水平的加工后,其外显记忆（自由回忆、再认）和内隐记忆（汉字补笔起动效应）的若干特点。发现：患者组外显记忆受损而内隐记忆正常;两组被试在深层意义加工中的外显记忆均强于在浅层表面加工中的外显记忆,这种语义易化现象以耗费更多的认知努力为代价,其中患者组耗费的尤多,而记忆效率却不及对照组。综上,脑外伤患者记忆功能呈损伤和保存双重性。     

事故驾驶员与安全驾驶员人格特征的比较研究

本研究采用柳井晴夫等人编制的新性格检查问卷,对６０名公交车驾驶员的人格特征进行了测量．结果表明：（１）事故组驾驶员与安全组驾驶员在五个人格特征上存在显著性差异,其中事故组驾驶员攻击性、神经质倾向较强,而持久性、协调性和同情性较差．（２）男性事故组驾驶员与安全组驾驶员在四个人格特征上存在显著性差异,其中事故组驾驶员攻击性和神经质倾向较强,但持久性和协调性较差。（３）女性事故组驾驶员与安全组驾驶员在两个人格特征上存在显著性差异,前者较后者攻击性强,但缺乏同情性．（４）性别在１２项人格特征上无显著性差异．本研究结果可为设计制定专门应用于交通领域的人格测验,以及对驾驶员的选拔、培训、教育和管理提供一定的理论依据．     

The Machines Take Over: A Comparison of Various Supervised Learning Approaches for Automated Scoring of Divergent Thinking Tasks

Traditionally, researchers employ human raters for scoring responses to creative thinking tasks. Apart from the associated costs this approach entails two potential risks. First, human raters can be subjective in their scoring behavior (inter-rater-variance). Second, individual raters are prone to inconsistent scoring patterns (intra-rater-variance). In light of these issues, we present an approach for automated scoring of Divergent Thinking (DT) Tasks. We implemented a pipeline aiming to generate accurate rating predictions for DT responses using text mining and machine learning methods. Based on two existing data sets from two different laboratories, we constructed several prediction models incorporating features representing meta information of the response or features engineered from the response’s word embeddings that were obtained using pre-trained GloVe and Word2Vec word vector spaces. Out of these features, word embeddings and features derived from them proved to be particularly effective. Overall, longer responses tended to achieve higher ratings as well as responses that were semantically distant from the stimulus object. In our comparison of three state-of-the-art machine learning algorithms, Random Forest and XGBoost tended to slightly outperform the Support Vector Regression.

不同阅读能力聋人语篇理解中连接推理的眼动比较

采用记录被试阅读完成后回答问题的正确率、反应时与眼动指标,试图探讨不同阅读能力聋人语篇理解中连接推理的加工特点与效率。结果表明:在语篇局部连贯中断情况下,高低阅读能力聋人在语篇理解过程中的连接推理加工是主动的即时性加工,而非语篇阅读完成后被动的延时性加工;但高阅读能力聋人能有效激活背景知识,所发生的连接推理加工是一个自动化的加工;低阅读能力聋人主动尝试即时激活背景知识、构建句子间的连接推理,但连接推理的加工还未达到自动化程度,推理加工的效率较低。
