Physical Abuse in U.S. Children: Risk Factors and Deficiencies in Referrals to Support Services

More than 600,000 U.S. children are reported for physical abuse annually. Risk factors are proposed in the literature, but a comprehensive, national assessment of risk factors and support services has not been conducted. An analysis of national data from the National Child Abuse and Neglect Dataset revealed that domestic violence, parental alcohol and drug use, prior child abuse and neglect, public assistance receipt, and child behavior problems are associated with higher odds of substantiated physical abuse reports, compared to unsubstantiated reports. Most families, however, failed to receive relevant support services for any of these risk factors. Screening by physicians, child protection workers, and others for these risk factors could help identify children at increased risk for physical abuse and inform prevention efforts and support-service provision.     

The topological approach to perceptual organization

To address the fundamental question of “what are the primitives of visual perception”, a theory of topological structure and functional hierarchy in visual perception has been proposed. This holds that the global nature of perceptual organization can be described in terms of topological invariants, global topological perception is prior to the perception of other featural properties, and the primitives of visual form perception are geometric invariants at different levels of structural stability. In Part I of this paper, I will illustrate why and how the topological approach to perceptual organization has been advanced. In Part II, I will provide empirical evidence supporting the early topological perception, while answering some commonly considered counteraccounts. In Part III, to complete the theory, I will apply the mathematics of tolerance spaces to describe global properties in discrete sets. In Part IV, I will further present experimental data to demonstrate the global-to-local functional hierarchy in form perception, which is stratified with respect to structural stability defined by Klein's Erlangen Program. Finally, in Part V, I will discuss relations of the global-to-local topological model to other theories: The topological approach reformulates both classical Gestalt holism and Gibson's direct perception of invariance, while providing a challenge to computational approaches to vision based on the local-to-global assumption.     

Speech‐evoked auditory brainstem responses reflect familial and cognitive influences

Cortical function and related cognitive, language, and communication skills are genetically influenced. The auditory brainstem response to speech is linked to language skill, reading ability, cognitive skills, and speech‐in‐noise perception; however, the impact of shared genetic and environmental factors on the response has not been investigated. We assessed auditory brainstem responses to speech presented in quiet and background noise from (1) 23 pairs of same sex, same learning diagnosis siblings (Siblings), (2) 23 unrelated children matched on age, sex, IQ, and reading ability to one of the siblings (Reading‐Matched), and (3) 22 pairs of unrelated children matched on age and sex but not on reading ability to the same sibling (Age/Sex‐Matched). By quantifying response similarity as the intersubject response‐to‐response correlation for sibling pairs, reading‐matched pairs, and age‐ and sex‐matched pairs, we found that siblings had more similar responses than age‐ and sex‐matched pairs and reading‐matched pairs. Similarity of responses between siblings was as high as the similarity of responses collected from an individual over the course of the recording session. Responses from unrelated children matched on reading were more similar than responses from unrelated children matched only on age and sex, supporting previous data linking variations in auditory brainstem activity with variations in reading ability. These results suggest that auditory brainstem function can be influenced by siblingship and auditory‐based communication skills such as reading, motivating the use of speech‐evoked auditory brainstem responses for assessing risk of reading and communication impairments in family members.     

The Construct and Measurement of Peace of Mind

Previous studies have shown that Asian American or Chinese individuals value low-arousal positive affect and a harmonious state of happiness more than European Americans do. However, the affective component of subjective well-being has mostly been defined as the presence of positive affect and the absence of negative affect. This definition emphasizes the importance of hedonic pleasure but fails to include the affect valued in Chinese culture. The present study developed the construct of peace of mind to describe the affective well-being valued in Chinese culture. Peace of mind was defined as an internal state of peacefulness and harmony. To develop a measure to assess peace of mind, three studies were conducted. Study 1 developed the Peace of Mind Scale (PoM), Study 2 established its validity as an affective well-being measure, and Study 3 found that individuals from Chinese cultures score higher on this scale than those from Western cultures. The results indicate that the PoM has good reliability and validity for measuring affective well-being. The cross-cultural validation also found that Taiwanese individuals scored higher on the PoM than European Americans, which provides further evidence of good construct validity of the PoM.     

人格特质对认知老化的影响及其机制

认知老化是指与年龄相关的认知功能损害.影响认知老化的因素很多,人格是这些因素背后的重要动因.当前有关人格与认知老化的研究主要探讨了不同人格特质对认知老化的具体影响及作用机制两个方面.尽管不同人格特质与认知老化的关系逐渐清晰起来,但现有研究在一些问题上仍存在争议.未来可以从不同研究范式的结果对比、人格特质对认知老化影响机制的内在问题、人格与人格特质的稳定性及其影响、人格特质对认知老化影响的本土化研究等几个方面进一步强化和拓展.     

壮族大学生一位数字词的SNARC效应

本研究以壮族大学生为被试,要求他们对壮语、汉语听觉数字词(实验一)或汉语、英语视觉数字词(实验二)进行奇偶判断。结果发现：(1)壮族大学生对汉语、壮语听觉数字词以及汉语、英语视觉数字词都表现出了SNARC效应。(2)数字词在听觉条件下和视觉条件下产生的SNARC效应的强度相当。(3)书写习惯也影响到壮语听觉数字的SNARC效应的方向。     

类别学习中的认知学习机制

采用归类任务,比较不同知识条件、不同特征呈现方式下,对非定义特征维度的掌握,验证类别学习的认知学习机制。结果发现对非定义特征维度的掌握,在样例特征固定位置呈现条件下较多,而在样例特征随机呈现条件下较少;在知识定义特征维度条件下较多,而在机械定义特征维度条件下较少。研究结果支持了类别学习的认知学习机制。

Psychological and socioeconomic health of community‐dwelling older adults

Different dimensions of health are intertwined. The purposes of this study were: (1) to investigate the psychological and socioeconomic health status of community‐dwelling older adults in Taiwan, and (2) to compare the psychological and socioeconomic health differences among people of different age groups, gender, marital status, and exercise habits. Using stratified random sampling, 384 Taiwanese community‐dwelling older adults were recruited for this survey research. Based on the Health Model of Older Adults, seven constructs were measured: (1) psychological health: sleep quality, emotional health, cognitive functioning, and health promotion behaviors; (2) socioeconomic health: social engagement, social support, and financial status. Results showed that most participants were in a good state of psychological and socioeconomic health, except that 38.02% of them suffered from sleep disruptions, and the majority of them were not involved in any social group, nor engaged in any volunteer work. Young‐old older adults had better psychological and socioeconomic health than middle‐old and old‐old older adults. Male older adults had better psychological health than female older adults; however, they had less social engagement and social support than female older adults. Married older adults and exercisers performed better in most of the psychological and socioeconomic health indicators than single/widowed older adults and non‐exercisers.     

When Low-Warmth Targets Are Liked: The Roles of Competence,Gender, and Relative Status

Previous research has shown that people use warmth and competence as basic dimensions to evaluate others and to interpret their behavior, but little research has examined the conditions under which low-warmth targets are liked. A series of 3 experiments involving 4 vignettes showed, in general, that low-warmth targets were better liked when they exhibited higher competence and that high-status persons displayed greater tolerance toward the low-warmth person of low status. Exceptions to these patterns were predicted and found as a function of the type of organizational context in which evaluations were made: groups that place priority on individual goals over common goals and groups that are performance oriented rather than relationship oriented. Target gender interacted with competence and relative status.
