潘菽心理学思想的后经验主义蕴含

今年是中国心理学泰斗,理论心理学奠基人潘菽先生诞辰110周年。纪念潘菽先生,意味着继承和发扬潘菽先生的心理学思想。从后经验主义理论心理学的视角来看,潘菽先生的心理学思想仍然具有当代性和启发性,特别是在强调理论对经验研究的优先地位、强调理论对经验现实的建构作用、强调理论的实践品性、强调理论的历史性向度,以及强调理论研究的中国心理学归宿等方面,显示出卓越的远见。     

Characteristics of Internet use in relation to game genre in Korean adolescents.

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.     

中小学生师生关系发展特征研究

本研究从学生角度去探讨中小学师生关系在亲密性、主动性和合作性等方面的特点。研究结果表明：师生关系亲密性总体呈随年级升高下降的趋势,女生在师生关系亲密性上得分比男生高;师生关系主动性总体随年级升高而降低,年级X性别的交互作用在中小学都很明提;师生关系合作性总体随年级升高而降低,年级X性别的交互作用最明显出现在小四至初二阶段;师生关系的亲密性、合作性和主动性三方面并非平均发展,合作性表现最高,主动性表现最低,亲密性居中。

Risk Patterns and Correlated Brain Activities. Multidimensional Statistical Analysis of fMRI Data in Economic Decision Making Study

Decision making usually involves uncertainty and risk. Understanding which parts of the human brain are activated during decisions under risk and which neural processes underly (risky) investment decisions are important goals in neuroeconomics. Here, we analyze functional magnetic resonance imaging (fMRI) data on 17 subjects who were exposed to an investment decision task from Mohr, Biele, Krugel, Li, and Heekeren (in NeuroImage 49, 2556–2563, 2010b). We obtain a time series of three-dimensional images of the blood-oxygen-level dependent (BOLD) fMRI signals. We apply a panel version of the dynamic semiparametric factor model (DSFM) presented in Park, Mammen, Wolfgang, and Borak (in Journal of the American Statistical Association 104(485), 284–298, 2009) and identify task-related activations in space and dynamics in time. With the panel DSFM (PDSFM) we can capture the dynamic behavior of the specific brain regions common for all subjects and represent the high-dimensional time-series data in easily interpretable low-dimensional dynamic factors without large loss of variability. Further, we classify the risk attitudes of all subjects based on the estimated low-dimensional time series. Our classification analysis successfully confirms the estimated risk attitudes derived directly from subjects’ decision behavior.     

Minority Representation in Special Education: 5-Year Trends

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.     

Deformation behaviour and 6H-LPSO structure formation at nanoindentation in lamellar high Nb containing TiAl alloy

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.
