The Effects of Darkness and Lightness Cues in the Visual Depiction of Political Actors Involved in Scandals: An Experimental Study     

Christian von Sikorski 《Communication Research Reports》2018,35(2):162-171

Reports about political scandals have increased lately. Yet the general impact of news visuals and the specific role of lightness and darkness cues in images of scandalized politicians remain unclear. With the help of an experiment, the present pilot study examined the influence of candidate images and the effects of particular image backgrounds (light versus dark). While the foreground of the image depicting a politician involved in a scandal remained unchanged, the background was systematically altered. The results revealed that a light background had a positive effect on recipients’ attitudes toward the politician. In contrast, participants exposed to a dark image background demanded a more severe punishment for the politician.  相似文献   

Handwriting isolated cursive letters in young children: Effect of the visual trace deletion     

《Learning and Instruction》2021

This study assesses the handwriting of isolated cursive letters in five-year-old children and the effect of a modification in visual feedback. Sixty-four children copied twelve cursive letters with an inking pen and a non-inking pen. Reducing visual feedback decreased the mean number of penlifts, and increased mean velocity and fluency. However, it increased the size of the letters (trajectory length) and reduced their quality. We suggest that processing visual feedback of the emerging visual trace may interrupt the fluency of the movement, while writing without seeing the trace may place greater emphasis on motor control and the use of somatosensory feedback. This study supplies reflection about sensory feedback and the moment when it should be provided in handwriting instruction. Practitioners should be aware that variation in the writing environment (surface, tools …) modifies sensory feedback and affects handwriting learning (gesture and outcome) in different manner.  相似文献   

A comparison of visual search strategies of elite and non-elite tennis players through cluster analysis     

Nicholas P. Murray 《Journal of sports sciences》2017,35(3):241-246

Considerable research has documented that successful performance in interceptive tasks (such as return of serve in tennis) is based on the performers’ capability to capture appropriate anticipatory information prior to the flight path of the approaching object. Athletes of higher skill tend to fixate on different locations in the playing environment prior to initiation of a skill than their lesser skilled counterparts. The purpose of this study was to examine visual search behaviour strategies of elite (world ranked) tennis players and non-ranked competitive tennis players (n = 43) utilising cluster analysis. The results of hierarchical (Ward’s method) and nonhierarchical (k means) cluster analyses revealed three different clusters. The clustering method distinguished visual behaviour of high, middle-and low-ranked players. Specifically, high-ranked players demonstrated longer mean fixation duration and lower variation of visual search than middle-and low-ranked players. In conclusion, the results demonstrated that cluster analysis is a useful tool for detecting and analysing the areas of interest for use in experimental analysis of expertise and to distinguish visual search variables among participants’.  相似文献

Exploring Verbal,Visual and Schematic Learners' Static and Dynamic Mental Images of Scientific Species and Processes in Relation to Their Spatial Ability     

Sulaiman M. Al-Balushi 《International Journal of Science Education》2013,35(3):460-489

The current study compared different learners’ static and dynamic mental images of unseen scientific species and processes in relation to their spatial ability. Learners were classified into verbal, visual and schematic. Dynamic images were classified into: appearing/disappearing, linear-movement, and rotation. Two types of scientific entities and their related processes were investigated: astronomical and microscopic. The sample included 79 female students from Grades 9 and 10. For the purpose of the study, three instruments were used. The Mental Images by Guided Imagery instrument was designed to investigate participants' visualization of static and dynamic mental images. The Water-Level Task was adopted to estimate participants' spatial ability. The Learning Styles Inventory was used to classify participants into verbal, visual and schematic learners. The research findings suggest that schematic learners outperformed verbal and visual learners in their spatial ability. They also outperformed them in their vividness of microscopic images; both micro-static and micro-dynamic images; especially in the case of appearing/disappearing images. The differences were not significant in the case of astronomical images. The results also indicate that appearing/disappearing images received the least vividness scores for all three types of learners.  相似文献   

鲍德里亚对马克思生产理论的重大误读     

王宏伟 《河南师范大学学报(哲学社会科学版)》2007,34(3):6-9

在早期鲍德里亚那里,符号构成了他分析现代资本主义社会的主导逻辑,这体现在他的《生产之镜》中对马克思的生产理论存在的两方面严重误读:一是认为马克思的生产理论并没有达到批判资本主义社会的效果,相反是维护了资本主义社会;二是认为只有以符号作为批判的基础才能达到批判的效果。但他的符号批判理论正由于对马克思生产理论的误读而与资本主义达成了共谋。  相似文献   

"国家的艺术形象"与"艺术的国家形象"--兼谈人民大会堂《江山如此多娇》的文化内涵     

傅爱国 《巢湖学院学报》2003,5(5):65-68

人民大会堂是我国最高的政治活动中心,又是最高的艺术殿堂,艺术与政治相互关系的理论上的阐释,在这里得当了最有效的实证;人民大会堂里的中国画如果被称谓“艺术的国家形象”,确切地说是最能代表着“国家的艺术形象”;人民大会堂的《江山如此多娇》画作,无论是创作主体,还是作品展示场地及其化内涵,都可以说是政治与艺术结合的结晶。  相似文献
