Eating pathology among adolescent girls with attention-deficit/hyperactivity disorder

The authors investigated prospectively assessed eating pathology (body image dissatisfaction and bulimia nervosa symptoms) among an ethnically and socioeconomically diverse sample of adolescent girls with attention-deficit/hyperactivity disorder-combined type (ADHD-C; n=93), ADHD-inattentive type (ADHD-I; n=47), and a comparison group (n=88). The sample, initially ages 6-12 years, participated in a 5-year longitudinal study (92% retention rate). After statistical control of relevant covariates, girls with ADHD-C at baseline showed more eating pathology at follow-up than did comparison girls; girls with ADHD-I were intermediate between these two groups. Baseline impulsivity symptoms, as opposed to hyperactivity and inattention, best predicted adolescent eating pathology. With statistical control of ADHD, baseline peer rejection and parent- child relationship problems also predicted adolescent eating pathology. The association between punitive parenting in childhood and pathological eating behaviors in adolescence was stronger for girls with ADHD than for comparison girls. Results are discussed in terms of the expansion of longitudinal research on ADHD to include female-relevant domains of impairment, such as eating pathology.     

Competitive versus cooperative attitudes in crossed categorization effects: testing the category dominance and equivalence models

Participants' (N = 256) competitive or cooperative attitudes toward national groups were activated by their reading 1 of 2 selected newspaper articles. Participants then judged the competence and attractiveness of a stranger who was categorized, separately for race and nationality, as belonging to an out-group or in-group. As predicted, the activated competitive attitude produced responses prescribed by the model of category dominance by nationality. In the condition of cooperative attitudes, however, competence responses were consistent with the model of equivalence (i.e., no effect of category) and attraction responses were consistent with the model of category dominance by race. The authors discuss reasons for the discrepant models in the condition of cooperative attitudes and the implications of these findings.     

Which is the compromise option? Information format and task format as determinants

When consumers must make a decision but are uncertain of their preferences, they often select a compromise choice. Early studies emphasized the relational properties of choice alternatives and indicated that the middle option, whose attribute values fall between the values of other alternatives, is always the compromise option. More recent studies have suggested that when consumers rate two attributes with the same metrics, the attribute–balance choice whose two attributes have equal ratings, might represent the compromise choice. We propose that the different characteristics of the middle and attribute–balance options—which may be compatible with certain determinants such as information and task formats—might be more salient and affect the relative attractiveness of each option. The results of three experiments confirmed this prediction: the middle option was more attractive in list‐by‐attributes and rejecting conditions, whereas the attribute–balance option was more attractive in list‐by‐alternatives and choosing conditions.

Examination stress and components of working memory

Previous research suggests that stress can influence a broad range of memory functions. In this study we investigated the effect of a naturalistic stressor, examination stress, on working memory in young adults. In order to accomplish this aim, participants were tested on psychological and hormonal measures of stress and on Digit Span, once during a low stress period and once during a high stress period. The high examination stress condition was associated with an increase in cortisol and subjective impressions of stress. Although Digits Forward performance did not vary with examination stress, Digits Backward performance improved. These findings suggest that mild increases in stress are associated with improvement in the manipulation component of working memory. However, no correlations were found between working memory and either cortisol or psychological stress. Thus the mechanism by which mild naturalistic stressors improve the manipulation component of working memory needs further investigation.     

Combining computer adaptive testing technology with cognitively diagnostic assessment

A major advantage of computerized adaptive testing (CAT) is that it allows the test to home in on an examinee's ability level in an interactive manner. The aim of the new area of cognitive diagnosis is to provide information about specific content areas in which an examinee needs help. The goal of this study was to combine the benefit of specific feedback from cognitively diagnostic assessment with the advantages of CAT. In this study, three approaches to combining these were investigated: (1) item selection based on the traditional ability level estimate (theta), (2) item selection based on the attribute mastery feedback provided by cognitively diagnostic assessment (alpha), and (3) item selection based on both the traditional ability level estimate (theta) and the attribute mastery feedback provided by cognitively diagnostic assessment (alpha). The results from these three approaches were compared for theta estimation accuracy, attribute mastery estimation accuracy, and item exposure control. The theta- and alpha-based condition outperformed the alpha-based condition regarding theta estimation, attribute mastery pattern estimation, and item exposure control. Both the theta-based condition and the theta- and alpha-based condition performed similarly with regard to theta estimation, attribute mastery estimation, and item exposure control, but the theta- and alpha-based condition has an additional advantage in that it uses the shadow test method, which allows the administrator to incorporate additional constraints in the item selection process, such as content balancing, item type constraints, and so forth, and also to select items on the basis of both the current theta and alpha estimates, which can be built on top of existing 3PL testing programs.     

语言与音乐活动的脑机制研究述评

语言和音乐是否具有相同加工机制的争论持续了很长时间。对失语症和失乐症的研究进行了简要回顾,并结合ERP和功能神经影像对语言和音乐的对比加工及同步加工分别进行研究,发现两者很大程度上存在加工机制的重合,即具有共同的神经加工源。对音乐加工的多个领域进行研究有助于语言加工研究的进展,两者的结合有着更深远的应用前景     

宗教体验的神经生理基础

宗教体验是人在宗教活动中的心态或体悟及伴随的情感体验,它是一个过程。其神经生理基础的研究表明,宗教体验过程中大脑的某些特定脑波或区域被激活。这些研究表明宗教体验与认知和情绪有关,在一定程度上与早期有关宗教体验实质的结论吻合,但这并不表明大脑中存在“上帝脑区”。该文简要介绍了宗教体验的概念、冥想以及基督教宗教体验神经生理基础的研究以及跨宗教传统的相关比较研究,并对该领域内的一些问题做出了说明     

Masculinity and Cognitive Age Perception: An Examination of their Relationship and Implications for Advertising Persuasion

This paper explores whether gender and sex role orientation, in terms of masculinity and femininity, may be associated with older cognitive age among young people. It predicts that masculinity should be associated with an older cognitive age. Two surveys (N?=?254 respondents aged 18–22 years and N?=?327 respondents aged 18–55 years), conducted in Taiwan, generally support this prediction. Moreover, this study predicts that masculinity influences people’s responses to media information that contains age cues, such as ads featuring models of various ages. The findings of another experiment (N?=?141 respondents) in Taiwan show that young participants who are more masculine like relatively older models to a greater degree, and the degree to which they like the model influences their attitudes toward the advertised brand.     

情感与人生:伦理学视野的审视

人是情感的动物.人的情感是以本能和欲望为基础,受理智影响和控制的心理感受.人的情感是一个多彩的、复杂的天空,存在着性质、广度、深度和强度的区别.从伦理学的角度看,可以根据是否有利于人的生存,从是否健康、是否丰富、是否持久、是否高尚、是否美好五个维度对人的情感进行价值审视.这五个维度也是情感是否有利于人的生存的五条标准,其中是否健康是底线标准,规定着情感的好坏善恶性质.情感对人生有全面、深刻而直接的影响,可以成为人生幸福的源泉,也可以成为人生痛苦的渊薮.情感需要理智的合理导向和控制,理智与情感以更好生存为取向实现和谐,才会有完整意义上的真正人生,才有人生的幸福.
