Culture, trauma, and wellness: a comparison of heterosexual and lesbian, gay, bisexual, and two-spirit native americans

In a community-based sample of urban American Indian and Alaska Native adults, 25 lesbian, gay, bisexual, and two-spirit participants were compared with 154 heterosexual participants with respect to sociodemographic characteristics, Native, cultural participation, trauma, physical and mental health, and substance use. Compared with their heterosexual counterparts, two-spirit participants reported higher rates of childhood physical abuse and more historical trauma in their families, higher levels of psychological symptoms, and more mental health service utilization. Two-spirit participants reported differences in patterns of alcohol use and were more likely to have used illicit drugs other than marijuana. Discussion and recommendations for health promotion interventions and future research are presented in consideration of an "indigenist" health model and the multiple minority status of two-spirit people.     

Contextual cuing based on spatial arrangement of color

Previous studies have demonstrated that, in visual search, repetition of a target's "context" significantly improves search performance (contextual cuing; Chun & Jiang, 1998). Context in those studies was defined as either spatial configuration or featural combination. In the present work, we demonstrate that repeating the spatial arrangement of object colors (conjunction of spatial configuration and featural combination) also leads to contextual cuing (Experiment 1). Experiments 2 and 3 rule out the possibility that the contextual cuing we find in Experiment 1 is caused only by the spatial configuration of color patches. Experiment 4 rules out the possibility that it is caused only by featural combination. Experiments 5 and 6 demonstrate that color-arrangement-based contextual cuing is an unconscious process. Experiments 7 and 8 demonstrate that contextual cuing seems to be more effective onchromatic (hue) variation than on achromatic (luminance) variation. In sum, our results demonstrate that contextual cuing is not merely associated learning in separate domains; it is a more integrated process than has perhaps been appreciated.     

Measures of prefrontal system dysfunction in posttraumatic stress disorder

Clinical observations have suggested that individuals who have suffered traumatic stressful events exhibit disruption in abilities mediated by frontal brain systems. Therefore, this study employed tasks sensitive to frontal lobe dysfunction, including delayed response (DR), delayed alternation (DA), object alternation (OA), delayed matching-to-sample (DMTS), and delayed nonmatching-to-sample (DNMTS), with participants having posttraumatic stress disorder (PTSD). Compared to controls, the PTSD participants were unimpaired on DA and DMTS, but they showed deficits on DR, OA, and DNMTS tasks. This pattern of results suggests disruption of functioning in selective prefrontal brain systems. Results are discussed in the context of the neuropsychological features of PTSD, as well as possible neuropathological and etiological underpinnings of this disorder.     

原因调节与反应调节的情绪变化过程

采用生理心理实验法研究忽视、抑制、重视、宣泄等方式调节负情绪的情绪变化过程,发现忽视有效减弱了主观感受和表情行为,并引起R-R问期更大的增加;抑制不能减弱主观感受,并引起手指脉搏血容振幅更大的增幅;重视增强了主观感受;宣泄增强了主观感受,并相对地减弱了生理激活水平。研究表明原因调节可以更有效地调整负情绪主观感受,反应调节使负情绪成分变化出现“水压模型”式循环动力特点;情绪调节过程实现着情绪在心理适应中的促进(或阻碍)作用。     

"米制"的时间层次网络结构研究

本研究通过两个实验来对米制时间顺序标码的层次网络结构的性质进行了探讨。研究结果表明,米制时间顺序标码系统要进行多层分组,由日子组成月份,由月份组成年份,最终形成了一个客观的、精确的层次网络的结构。不同层次的项目之间因加工方式的不同而出现了层次效应或者越界效应,同一层次的项目还在继续进行分组,不同小组之间出现了距离效应;被试对米制的时间信息标码层次网络表征的加工,是采用了“顶层一底层”的方向;对两个刺激项目进行直接比较判断或运算这两种加工的难易是不同的;本研究中没有发现方向效应。     

Field dependence versus field independence of students with and without learning disabilities

The Group Embedded Figures Test of Oltman, Raskin, and Witkin was administered to 60 high school students (30 with learning disabilities and 30 without learning disabilities) to measure their cognitive styles of field dependence versus field independence. The analysis showed that the students with learning disabilities scored as more field dependent than those without learning disabilities.     

Item selection methods with exposure and time control for computerized classification test

Computerized classification testing (CCT) commonly chooses items maximizing information at the cut score, which yields the most information for decision-making. However, a corollary problem is that all examinees will be given the same set of items, resulting in high test overlap rate and unbalanced item bank usage, which threatens test security. Moreover, another pivotal issue for CCT is time control. Since both the extremely long response time (RT) and large RT variability across examinees intensify time-induced anxiety, it is crucial to reduce the number of examinees exceeding the time limitation and the differences between examinees' test-taking times. To satisfy these practical needs, this paper proposes the novel idea of stage adaptiveness to tailor the item selection process to the decision-making requirement in each step and generate fresh insight into the existing response time selection method. Results indicate that a balanced item usage as well as short and stable test times across examinees can be achieved via the new methods.     

How using a paper versus mobile calendar influences everyday planning and plan fulfillment

This research examines how using a paper versus mobile calendar influences everyday planning and plan fulfillment behavior. Consumers are rapidly moving from paper to mobile calendars for convenience, but this research shows that doing so may lead individuals to be less successful in effectively developing and implementing their plans. In three studies, we demonstrate that compared with mobile calendar users, paper calendar users develop higher-quality plans and are more successful in plan fulfillment. We provide evidence that this happens because paper calendar users take a broader, big-picture perspective during planning, which also leads to higher-quality plan development and a greater likelihood of plan fulfillment. When mobile calendar users use a mode that also provides a broader perspective, their plan quality increases.     

Cross-cultural similarity in the love attitudes scale: short form.

Recently, Hendrick, Hendrick, and Dicke presented two short forms of the Love Attitudes Scale, the first using 24 items with 4 items for each subscale and the second using 18 items with 3 items for each subscale. Their data indicated that the two short versions have even stronger psychometric properties than the original scale. This study reports an 18-item short form of the scale developed independently in Taiwan using 460 graduate and undergraduate students in the fall semester of 1997. The results demonstrated a remarkable cross-cultural similarity in the development and response to the short form of the scale and its applicability to a broader cultural setting.
