How infants use vision for grasping objects

The role of vision was examined as infants prepared to grasp horizontally and vertically oriented rods. Hand orientation was measured prior to contact to determine if infants differentially oriented their hands relative to the object's orientation. Infants reached for rods under different lighting conditions. Three experiments are reported in which (1) sight of the hand was removed (N = 12), (2) sight of the object was removed near the end of the reach (N = 40, including 10 adults), and (3) sight of the object was removed prior to reach onset (N = 9). Infants differentially oriented their hand to a similar extent regardless of lighting condition and similar to control conditions in which they could see the rod and hand throughout the reach. In preparation for reaching, infants may use the current sight of the object's orientation, or the memory of it, to orient the hand for grasping; sight of the hand had no effect on hand orientation.     

加强实践环节的铁路线路课程设计探索

线路课程设计是一门综合运用理论和专业知识的实践课程,对工程实际经验依赖性很强。本文分析了目前铁道工程线路课程设计培养现状,论述了加强实践环节的必要性,并开展了加强赴现场模拟踏勘、邀请线路设计专家入校讲解等尝试,以期为类似实践性较强的课程设计提供参考。

故土情结与本真感悟——论萧红的乡土小说

萧红的乡土小说十分尊重自己内心的本真感悟。她凭着对家园故土、东北黑土地文化及家乡“子民们”生存困境的本真描绘和在创造中自由自在的艺术追求,在众多乡土作家中独树一帜。可以说,故土情结玉成了萧红小说的成就,而她的成就又构建于她写家乡人的生存状态与生命挣扎。她自觉秉承鲁迅的现实主义创作风格,但与鲁迅又不尽相同。

Interactive Effects Between Maternal Parenting and Negative Emotionality on Social Functioning Among Very Young Chinese Children

Research Findings: This study examined how child negative emotionality interacted with mothers’ self-reported parenting in predicting different aspects of social functioning among very young Chinese children. A total of 109 Chinese nursery children in Hong Kong participated with their parents. Maternal supportive and aversive parenting practices were reported by mothers, and child negative emotionality and social functioning were reported by both mothers and fathers. The results revealed interaction effects between child negative emotionality and mothers’ self-reported parenting on children’s internalizing problems, externalizing problems, and social-emotional skill deficiency. Specifically, children with high negative emotionality were more susceptible to the negative effects of aversive parenting (i.e., showing more internalizing and externalizing problems when exposed to aversive parenting) than their peers with low negative emotionality. Negative emotionality also placed young children at risk for social-emotional skill deficiency, especially when they received less support from their mothers compared to their peers. Practice or Policy: Special attention should be paid to the social functioning of Chinese children with higher levels of negative emotionality, because these children are more vulnerable to poor-quality parenting at a very young age.
