Icon flickering, flicker rate, and color combinations of an icon's symbol/background in visual search performance

The effects of color combinations of an icon's symbol/background and components of flicker and flicker rate on visual search performance on a liquid crystal display screen were investigated with 39 subjects who searched for a target icon in a circular stimulus array (diameter = 20 cm) including one target and 19 distractors. Analysis showed that the icon's symbol/background color significantly affected search time. The search times for icons with black/red and white/blue were significantly shorter than for white/yellow, black/yellow, and black/blue. Flickering of different components of the icon significantly affected the search time. Search time for an icon's border flickering was shorter than for an icon symbol flickering; search for flicker rates of 3 and 5 Hz was shorter than that for 1 Hz. For icon's symbol/background color combinations, search error rate for black/blue was greater than for black/red and white/blue combinations, and the error rate for an icon's border flickering was lower than for an icon's symbol flickering. Interactions affected search time and error rate. Results are applicable to design of graphic user interfaces.     

Skin conductance as an indicator of anticipated concealed knowledge

The present study investigated the effects of anticipation on skin conductance while participants were answering a set of questions which included one of concealed knowledge. Two experiments were conducted. In Exp. 1, 26 participants completed one experimental session. Each participant was asked to choose one two-digit number from 10 to 99 and was presented 19 other randomly generated two-digit numbers. The list of numbers was then presented to the participant on a computer screen, with a 60-sec. interval occurring every two questions. The participant-selected number was defined as the target question which was randomly placed within the 4th to 17th item of 20 questions stated as follows: "Is your selected number?" The participant was asked to answer "No" to all questions. The skin-conductance response to each question was measured. In Exp. 2, the experimental procedure was the same as that in Exp. 1 except each participant first answered 10 nontarget questions, then answered a target question with the participant's selected number, and then answered another 10 nontarget questions. There were a total of 21 questions. Analysis indicated participants in both experiments generated the highest mean skin conductance while answering the target questions, followed by lower amplitudes to questions prior to and after the target question. The skin-conductance response pattern can be used to identify the psychological process of anticipation of concealed information.     

Visualized representation of visual search patterns for a visuospatial attention test

Cancellation tests have been widely used in clinical practice and in research to evaluate visuospatial attention, visual scanning patterns, and neglect problems. The aim of the present work is to present a visualized interface for the visuospatial attentional assessment system that can be employed to monitor and analyze attention performance and the search strategies used during visuospatial processing of target cancellation. We introduce a pattern identification mechanism for visual search patterns and report our findings from examining the visual search performance and patterns. We also present a comparison of results across various cancellation tests and age groups. The present study demonstrates that our system can obtain more processing data about spatiotemporal features of visual search than can conventional tests.     

狂便谈禅,悲还说梦--龚自珍佛教思想管窥

龚自珍堪称近代中国思想解放的精神先驱.当激进的改革要求遭受挫折后,龚自珍便将沉沉心事投向了佛学.佛学赋予的智慧和普渡众生的济世观念使龚自珍受益颇深,一方面既找到了一种崇高的精神依托,另一方面同样也可以借此学说以申张自己励志改革的决心.在龚自珍那里,佛学兼具理性与信仰的双重情感,它具有宗教性,但更是龚自珍批判礼教、倡导经世致用之学的理论渊源之一.而这一自佛学中吸取营养的学术风气后来渐至发扬光大,终于形成了一股强大的社会改良思潮,也开启了近代佛学的思辨之路.     

哈尼族村社祭司——咪谷

咪谷是哈尼族社会生活中重要角色人物。他既是自然属性的人,又是神灵的化身;他曾经既是行政首长,又是宗教祭司;他是做人的楷模,是村寨生活精神的象征,是人生价值的追求目标。本文阐述咪谷产生的历史背景及条件的基础上,阐明咪谷与莫批在哈尼族社会中地位和不同作用,提出了咪谷精神在当今构建和谐村社中具有重要的现实意义。     

咒语的本源、演变、基本特征以及与祷词、神谕的区别

巫术与神灵崇拜仪式中出现的仪式语言有咒语、祷词与神谕。在现代社会尚存的以民俗信仰为主的中国本土传统的宗教仪式中,三种仪式语言往往连用或混杂在一起,而咒语的情况最为复杂。原始形态的咒语源自巫术活动中的语言灵力崇拜,而在后世有各种与神灵崇拜相结合的形态。依照咒语形成的原理和基本特征,可以判别具体仪式中咒语的灵力构成形态。根据三种仪式语言的性质、特征的差异,以及所用词句的不同,可以将三者加以比较细致的区分,借此可以明了特定仪式的超自然力崇拜的具体状况。     

应当关注时间心理无意识的研究

随着心理无意识研究在记忆、学习和思维等领域的兴起,内隐时间认知也逐步成为时间心理学中的一个研究热点。本文分析了探究内隐时间认知的四种方法:分离范式、序列学习范式、表征动量范式和计时分布相关范式,指出内隐时间认知实验范式在无意识时间人格与社会心理学中的研究也是有相当前景的。     

The association between parents' ethnic socialization and positive and negative interethnic contact among majority and minority groups in China and the moderating role of essentialism

In a multiethnic country like China, ethnic membership is an important dimension of social construction, and interethnic contact is a necessary component of social interactions. Family is the context where ethnic socialization takes place and where parents play a relevant role. The present study focused on the Hui-Han interethnic context. Measures of perceived parent's ethnic socialization, interethnic contact, and essentialism were administrated to Hui minority (N = 560) and Han majority (N = 954) secondary students. Results indicated that parents' positive ethnic socialization (cultural socialization/pluralism, promotion of harmony) was associated with greater positive and lower negative contact, while negative ethnic socialization (preparation for bias, promotion of mistrust) had opposite effects. Essentialist views of ethnicity moderated the associations of perceived parents' positive ethnic socialization with positive contact: the association between positive ethnic socialization and positive contact was stronger among individuals with lower (vs. higher) essentialist views. Results did not differ across the majority and the minority group. Implications for prompting positive interethnic interactions and preventing negative contact are discussed.     

中国人的群体参照记忆效应

在自我参照效应范式中加入参照认同群体加工任务,比较了中国被试在参照中国人和参照美国人进行记忆加工时的再认率及“记得”与“知道”判断的成绩。两项实验结果一致表明,参照中国人加工的再认成绩显著高于参照美国人,表明记忆加工的认同群体参照效应,而在“记得”与“知道”指标上并无差异;参照中国人加工的再认成绩和“记得”判断成绩显著低于自我参照加工。根据个体自我、关系自我和集体自我的分类方法,自我参照效应反映了个体自我对于记忆加工的影响,群体参照效应则主要反映了集体自我的影响     

Numeral size, spacing between targets, and exposure time in discrimination by elderly people using an lcd monitor

The present study investigated the effects of numeral size, spacing between targets, and exposure time on the discrimination performance by elderly and younger people using a liquid crystal display screen. Analysis showed size of numerals significantly affected discrimination, which increased with increasing numeral size. Spacing between targets also had a significant effect on discrimination, i.e., the larger the space between numerals, the better their discrimination. When the spacing between numerals increased to 4 or 5 points, however, discrimination did not increase beyond that for 3-point spacing. Although performance increased with increasing exposure time, the difference in discrimination at an exposure time of 0.8 vs 1.0 sec. was not significant. The accuracy by the elderly group was less than that by younger subjects.
