The Role of Sketching States in the Stimulation of Idea Generation: An Eye Movement Study

Sketching is widely used in design to generate creative ideas. Design studies present stimuli during sketching to enhance creativity. This study examines the effect of stimuli presented during different sketching states, especially of those presented during the stuck period. It conducted a sketching experiment that enrolled 41 students with an average of 5.7 years’ practice in industrial design. The sketching with stimuli presented at regular intervals, those with stimuli presented during the stuck period, and those without stimulus were compared. Eye movements during the sketching processes were recorded. The attention to stimuli, and the direct applications of stimuli to design ideas, and the idea connection and idea differentiation were analyzed. Participants sketching with stimuli presented during the stuck period had a higher sketching quality, compared with those in other experimental conditions. They fixated longer on stimuli, built more links among related ideas, and had a more differentiated and balanced exploration. This study then proposed the mechanisms of stimuli processing. The stimuli presented at regular intervals were stored and acted as additional memory. The stimuli presented during the stuck period were dissected and acted as supporter, inducing a more creative sketching.     

Electromechanical behavior of single-walled carbon nanotube thin films

Carbon nanotubes have been intensively studied owing to their great potential in nanoelectronics and nanomechanical devices. Recently, experimental results have shown that single-walled carbon nanotubes (SWCNTs) change their electronic properties when subjected to strain. In this study, the electromechanical characteristics of SWCNT networks were investigated for the application of printable strain sensors on flexible substrates. SWCNT films were formed on plastic substrates of poly(ethylene terephthalate) using a spray process. In this manner, we were able to control the transparency and obtain uniform electrical properties of the films. The films are isotropic on account of the random orientation of bundles of SWCNTs. Experimental results showed a nearly linear change in the resistance across a film when it was subjected to tensile strain, even in the inelastic range of the flexible substrate. The results demonstrate the potential use of SWCNT films for highly sensitive printable strain sensors on a macroscale.     

情绪性工作记忆对选择性注意的影响

选取大学本科生33名,采用情绪启动范式与再认范式相结合,要求被试依次完成情绪词识记、目标面孔性别判断及情绪词再认任务,探讨保存于工作记忆中的情绪性刺激对面孔性别判断任务的影响。结果显示:(1)在中性和恐惧情绪启动刺激条件下,被试对目标面孔性别判断的反应时要显著长于悲伤条件。(2)在愉悦情绪启动词条件下,线索提示有效性差异显著;在无效线索提示条件下,启动刺激的不同情绪效价差异显著。(3)对情绪面孔性别与被试性别一致性/非一致性两种条件下反应时对比发现,男、女被试在情绪面孔性别判断任务中均表现出异性相吸效应。综上所述,保存在工作记忆中情绪刺激会对面孔性别的识别产生自上而下的影响。

移植免疫中微嵌合现象给我们的思考

随着移植免疫学研究的不断深入发展,诱导免疫耐受克服移植排斥反应已成为器官移植的主要研究目标。Starzl提出“双向移植排斥理论”并阐述临床使用免疫抑制药物下移植排斥反应的特点,突破了原有单向移植排斥理论的框架。“双向移植排斥理论”及理论内存在的问题给予我们众多有益的思考,在移植免疫学研究中,只有坚持用系统原则动态的看待事物间的联系与矛盾,进行科学实践,才能获得正确的理论,从而进一步推动移植免疫学的发展。     

槟榔时尚与疾病

Perceived Parenting Styles and Cultural Influences in Adolescent’s Anxiety: A Cross-Cultural Comparison

A growing body of literature links particular parenting practices with negative child outcomes including greater anxiety symptoms among western societies. However, the effects of cultural differences on such linkages have not been adequately addressed in the anxiety literature. This study therefore aimed to examine the relationship between perceived parenting style and anxiety among Malay, Chinese, Indian, Arab and European/American (Caucasian) origins adolescents and the possible cultural group influences on this relationship was studied. Using multiple cluster sampling, a total of 227 students (122 boys and 105 girls) aged 13–18 years was selected. They completed questionnaires measuring parental rearing behaviors (EMBU-C) and anxiety symptoms scale (SCAS). Results indicated that in comparison to the European/American; Asian samples reported greater anxiety symptoms on all subscales of anxiety. Parental rejection, anxious rearing and control/over protection were correlated to higher anxiety independent of cultural group but these associations were stronger for Caucasians. Parenting styles as predictor of anxiety were found to be cross culturally different. Although European/American adolescents rated their parents as least over controlling, it was significant predictor of anxiety. This study provides evidence for the notion that relationship between parenting factors and anxiety were different across cultural contexts.
