The motivations of adolescents who are addicted to online games: a cognitive perspective

This research explored, from the perspective of cognitive theory, the psychological motivations of Taiwanese adolescents who are addicted to online games. Study 1 focused on the differential motivations between the addicts and nonaddicts. The findings revealed that the addicts exhibited higher intrinsic than extrinsic motivation, whereas the nonaddicts showed an opposite relationship. The intrinsic motivation of the addicts was also higher than the nonaddicts. The results imply that intrinsic motivation plays a crucial role in gaming addiction. Study 2 was conducted to examine whether four factors that moderate the detrimental effect of extrinsic motivators on intrinsic motivation would function as predicted. Results indicated that extrinsic rewards would undermine intrinsic motivation when they were high expectancy, high relevance, tangible, and noncontingent. Thus, players' intrinsic motivation would be higher when extrinsic rewards were low expectancy, low relevance, intangible, and contingent. This article provides insights into the differential motivations of the addicted players and how to employ intrinsic motivators to affect their intrinsic motivation.     

Spatial accuracy demand in aiming movements: kinematic analysis of subtended angle and tolerance width

Subtended angle has been assumed to be an important factor in both response programming time and kinematic characteristics of aiming movements. Support for this assumption has come mainly from studies in which circular targets have been used. However, with circular targets, the subtended angle covaries with the size of the target in the principal direction of the movement (tolerance width). The purpose of this study was to examine the effects of tolerance width and subtended angle on aiming movement with multiple targets. Participants first hit a 5-cm-diameter circular target located 8 cm to the left of a starting position and then moved another 8 cm left to hit either a 5-cm diameter circular target or a 5- x 1-cm rectangular target oriented either horizontally or vertically, depending on the condition. Analysis showed that reaction times and movement times were longer for the vertical rectangular target, which had a smaller tolerance width than the other two targets. In addition, the vertical rectangular target also showed a greater percentage of secondary-submovement trials, lower movement velocity, and higher peak vertical displacement. Overall, the results indicate that the tolerance width of the target may impose more constraints on aiming movements than subtended angle.     

青少年期母子性格与家庭亲密度的关系:性格喜好的作用

研究旨在考察性格喜好与母子性格、家庭成员亲密度的关系以及性格喜好在其他两个变量之间的中介作用。成都市632对初高中学生及其母亲分别自评并填写了艾森克人格问卷,同时评价喜欢对方性格的程度。另外,青少年还报告了与家庭成员的亲密程度。通过相关分析、多元方差分析、层级回归分析以及结构方程模型建模,结果发现：性格喜好与母亲性格、青少年性格均有显著关系,青少年对母亲的性格喜好程度与家庭成员间的亲密感有显著正相关。青少年性格和青少年对母亲的性格喜好程度能直接预测家庭成员亲密度,同时青少年和母亲的性格还通过青少年对母亲的性格喜好程度间接作用于家庭亲密度,提示性格喜好在二者的关系中发挥了重要的中介作用。     

Individual Differences in Attitude-Behavior Consistency: The Prediction of Contraceptive Behavior

A model of individual differences that moderate attitude-behavior consistency was developed and tested in the context of predicting use consistency of the diaphragm. Variables hypothesized to moderate the attitude-behavior relationship included reactions to major life changes, the attitudes and opinions of others, sexual interest, locus of control, and the perceived susceptibility to pregnancy. Attitudes were conceptualized in terms of a Relative Contraceptive Utility (RCU), which was defined as the difference between the attitude toward the diaphragm and the attitude toward becoming pregnant. Women (N = 110) who attended family planning clinics in the New York Qty area and who used the diaphragm for an 8-month period were interviewed in the context of a 3-wave panel design. A threshold function between RCU and behavior was observed, such that when RCU was above an empirically derived cutoff, women tended to use the diaphragm consistently over an 8-month period. For women with RCUs below the cutoff, attitudes were unrelated to behavior. Inconsistency of diaphragm use for these latter women was best predicted by negative reactions to close friends' experiences with the diaphragm, low levels of perceived susceptibility to pregnancy, alcohol consumption, concern about becoming too old to have children, a preference for nonromantic sex, and the partner's unwillingness to refrain from sex if the women was not prepared.     

Age-related differences in the distractor previewing effect with schematic faces of emotions

Young and older adults searched for a unique face in a set of three schematic faces and identified a secondary feature of the target. The faces could be negative, positive, or neutral. Young adults were slower and less accurate in searching for a negative face among neutral faces when they had previewed a display of negative faces than when they had previewed neutral faces, indicating an emotional distractor previewing effect (DPE), but this effect was eliminated with inverted faces. The DPE is an index of inter-trial inhibition to keep attention away from previewed, non-target information. Older adults also showed such an emotional DPE, but it was present with both upright and inverted faces. These results show that, in general, both young and old participants are sensitive to trial history, yet the different patterns of results suggest that these two groups remember and use different types of perceptual information when searching through emotional faces.     

Reflecting Absence: Representing the Extraordinary Deaths of Ordinary Sailors in the Media

This study undertakes a comparative analysis of the commemorative discourse used by the South Korean media, family members, and the general public in response to the deaths of 46 sailors on board a navy ship that was sunk by a North Korean torpedo in 2010. It identifies differences in the methods of remembrance among the different groups, with the media focusing on human values, professional ethics, and universal norms, while family members recalled everyday experiences with the deceased and stressed acceptance of death and the general public emphasized heroism, immortality, and national solidarity. This study discusses the differences in the understanding of death between South Koreans and Westerners.     

Modeling Concordance Correlation Coefficient for Longitudinal Study Data

Measures of agreement are used in a wide range of behavioral, biomedical, psychosocial, and health-care related research to assess reliability of diagnostic test, psychometric properties of instrument, fidelity of psychosocial intervention, and accuracy of proxy outcome. The concordance correlation coefficient (CCC) is a popular measure of agreement for continuous outcomes. In modern-day applications, data are often clustered, making inference difficult to perform using existing methods. In addition, as longitudinal study designs become increasingly popular, missing data have become a serious issue, and the lack of methods to systematically address this problem has hampered the progress of research in the aforementioned fields. In this paper, we develop a novel approach to tackle the complexities involved in addressing missing data and other related issues for performing CCC analysis within a longitudinal data setting. The approach is illustrated with both real and simulated data.     

不同年龄倒班与正常班医护人员睡眠质量和睡眠规律性的比较

应用自行设计的睡眠调查表对443名20—45岁医护人员的睡眠质量和睡眠规律性作了调查。睡眠质量问卷包括睡眠一般评价、是否失眠及服药、入睡是否顺利、睡眠期间觉醒情况、梦记忆情况和觉醒期间精力情况六个项目。 调查结果发现倒班组与正常班组睡眠质量的差异表现在总分和几乎所有的项目上,倒班组值夜班后睡眠质量和睡眠规律性均很差;倒班组和正常班组睡眠质量均随年龄和工龄的增长而下降,因此倒班对睡眠的影响随年龄和倒班工龄的增长而加剧。本研究还发现,过去多年倒班、近三年前转为正常班的工作人员的睡眠有所恢复。     

Concerns of Older Veteran Callers to the Veterans Crisis Line

When the Veterans Crisis Line (VCL) was implemented, it was uncertain if veterans, and particularly older male veterans, would utilize the service. We examined VCL use by a growing group of veterans at increased risk for suicide: those aged 60 and older. Real‐time clinical data were gathered from a weekly random sampling of calls. Approximately 25% of calls were from veterans aged 60 or older; over 80% reported benefit from the call. Several significant differences in presenting concerns between older and younger callers were found. Targeted outreach to encourage older veterans to use the VCL is suggested.
