As the number of internet users increases, a new game genre using the internet as a networking tool is emerging. Some game genres are regarded as having greater addiction potentials than others. Games and the internet are closely related. We investigated games frequently used by adolescents and classified each of them with the help of game professionals. We also examined internet use patterns to identify relationships between game genre and internet use patterns. 627 middle school and high school students (male 488, female 139) completed questionnaires concerning computer and game use patterns and Korean internet addiction scales. Game genres were divided into eight criteria (simulation, role playing game, web board, community, action, adventure, shooting, and sports). Using Korean internet addiction scales, 627 participants were divided into a normal group (474), a potential risk group (128), and a high-risk group (25). Each group showed significant differences in total internet addiction scores. We classified players into specific game users based upon the game types they most prefer. Role playing game users showed significantly higher internet addiction scores than web board and sports game users. Game and internet addictions are also connected with interpersonal relationship patterns. We suggest that users of some game genre have unique psychological addiction potentials that are different from others and that this influences both game selection and internet use. 相似文献

习惯空间术语对空间认知的影响再探 总被引:1,自引:0,他引:1
考察习惯的空间术语对空间认知的影响。实验1考察在有空间语言线索提示下南、北方被试空间认知的差异。结果表明,当给予空间语言线索提示时,南、北方被试都更多地以所提示的空间参考框架定向。但语言线索对南、北方被试影响不同。实验2考察非定向性的习惯空间术语对空间认知的影响。结果表明,“南下北上”的术语影响被试对空间的认知。 相似文献

The disproportionate representation of minority students in special education has been a concern for decades. The Individuals with Disabilities Education Act mandates states to have policies and procedures in place to prevent inappropriate over identification or disproportionate representation by race and ethnicity of students with disabilities. The purpose of this study was to investigate the current status of minority representation in special education given the mandate and related efforts to reduce overrepresentation and to identify trends for the 5-year period from 2004 to 2008. Growth models were used to analyze trends in national data collected from the 50 states and the District of Columbia for these 5 years. Findings indicate some improvements from 10 years ago, especially noteworthy are a significant decrease in the number of African American students and a moderate decrease in the number of Hispanic students categorized as having intellectual disabilities. However, during the same period, the number of Hispanic students in learning disabilities increased. Otherwise, the trend of racial/ethnic representation in special education remains the same as it was a decade ago. 相似文献

Microstructure and deformation mechanisms at a nanoindentation in the lamellar colony of high Nb containing TiAl alloy have been studied using the focused ion beam and the transmission electron microscopy. Considerable deformation twins are observed around the nanoindentation, and a strain gradient is generated. A continuous change in the bending angle of the lamellar structure can be derived, and a strain-induced grain refinement process is observed as various active deformations split the γ grains into subgrains. In addition to all possible deformation mechanisms (ordinary dislocation, super-dislocation and deformation twining) activated due to the heavy plastic deformation, a 6-layer hexagonal (6H) long-period stacking ordered structure is identified for the first time near the contact zone and is thought to be closely related to the glide of partial dislocations. 相似文献

日本华严宗在镰仓时代形成了两大派别,它们的代表人物分别是明惠和凝然。本文首先阐明了明惠、凝然与中国华严思想家李通玄、法藏等人的思想联系,进而对他们各自提出的道统学说进行了分析,再进一步考察了中国华严思想史上的不同流派以及中国华严教团的成立问题,澄清了学术界对此存在的长期误解,提出了中国华严教团形成于宋代的新观点。最后,对华严宗道统说在中日两国形成的历史过程和它们对近现代佛教研究造成的影响进行了批判性总结。 相似文献
