Personal and impersonal stimuli differentially engage brain networks during moral reasoning

Moral decision making has recently attracted considerable attention as a core feature of all human endeavors. Previous functional magnetic resonance imaging studies about moral judgment have identified brain areas associated with cognitive or emotional engagement. Here, we applied graph theory-based network analysis of event-related potentials during moral decision making to reveal the personal/impersonal distinction in the organization of functional connectivity. Our results indicated that the personal task had more larger long-range connections involved in frontal regions and the right hemisphere, and higher network efficiency of some frontal electrodes such as F2 than the impersonal. These might be related to brain resource reorganization contributing to efficient conflict resolution. These findings provide new insights into neural mechanisms of moral dilemmas.     

Autonomous Motivation and Chinese Adolescents’ Creative Thinking: The Moderating Role of Parental Involvement

The relationship between motivation and creativity has long been of interest and many studies have been conducted to demonstrate the role of intrinsic and extrinsic motivation on creativity. The autonomous/controlled distinction of motivation suggested by self-determination theory (SDT) provides a new perspective on the motivation issue. Based on both SDT and the confluence approach of creativity, this study attempted to examine the relationship between autonomous/controlled motivation and creative thinking as well as the moderating role of parental involvement/autonomy support on this relationship. Five hundred and fifty Chinese high school students participated in the study and their autonomous/controlled motivation, parental involvement/autonomy support, and creative thinking were measured. Results indicated that autonomous motivation positively predicted creative thinking, and this relationship was moderated by parental involvement. For both junior and senior high school students, autonomous motivation was more strongly related to creative thinking when there was high maternal involvement. The moderating role of paternal involvement, however, differed between junior and senior high school students and there existed a 3-way interaction effect. Implications of this study for cultivating creativity among Chinese adolescents are also discussed.     

The use of a wearable camera improves autobiographical memory in patients with Alzheimer's disease

Despite the marked impairment of recent episodic memories in Alzheimer's disease, there have been few attempts to rehabilitate these deficits. We used a novel external memory aid to promote recall of episodic memories in patients with mild to moderate Alzheimer's disease. SenseCam, a small wearable camera, recorded significant events in the lives of six Alzheimer's disease patients. Every two days for two weeks each patient's memory for an event was assessed, followed by a structured review of the SenseCam images. Longer-term recall was tested one and three months later. A written diary control condition followed the same procedure. Across 40 events the SenseCam review method resulted in significantly more details of an event being recalled over two weeks than the written diary method in five out of the six patients. At three months post event, four out of five patients (one had dropped out) recalled significantly more details of events in the SenseCam condition while the other patient showed no significant difference. Viewing SenseCam images of personally experienced events may significantly improve autobiographical memory in patients with even moderate Alzheimer's disease.

Developmental Features of Rapid Aiming Arm Movements Across the Lifespan

Using a lifespan approach, the authors investigated developmental features of the control of ballistic aiming arm movements by manipulating movement complexity, response uncertainty, and the use of precues. Four different age groups of participants (6- and 9-year-old boys and girls and 24- and 73-year- old men and women, 20 participants in each age group) performed 7 types of rapid aiming arm movements on the surface of a digitizer. Their movement characteristics such as movement velocity, normalized jerk, relative timing, movement linearity, and intersegment intervals were profiled. Analyses of variance with repeated measures were conducted on age and task effects in varying movement complexity (Study 1), response uncertainty (Study 2), and precue use (Study 3) conditions. Young children and senior adults had slower, more variant, less smooth, and less linear arm movements than older children and young adults. Increasing the number of movement segments resulted in slower and more variant responses. Movement accuracy demands or response uncertainty interacted with age so that the 6- and 74-year-old participants had poorer performances but responded similarly to the varying treatments. Even though older children and young adults had better performances than young children and senior adults, their arm movement performance declined when response uncertainty increased. The analyses suggested that young children's and senior adults' performances are poorer because less of their movement is under central control, and they therefore use on-line adjustments. In addition, older children and young adults use a valid precue more effectively to prepare for subsequent movements than do young children and senior adults, suggesting that older children and young adults are more capable of organizing motor responses than arc young children and senior adults.     

Maternal Socialization Goals,Parenting Styles,and Social-Emotional Adjustment Among Chinese and European American Young Adults: Testing a Mediation Model

The authors compared the associations among perceived maternal socialization goals (self-development, filial piety, and collectivism), perceived maternal parenting styles (authoritative, authoritarian, and training), and the social-emotional adjustment (self-esteem, academic self-efficacy, and depression) between Chinese and European American young adults. The mediation processes in which socialization goals relate to young adults’ adjustment outcomes through parenting styles were examined. Results showed that European American participants perceived higher maternal self-development socialization goals, whereas Chinese participants perceived higher maternal collectivism socialization goals as well as more authoritarian parenting. Cross-cultural similarities were found in the associations between perceived maternal authoritative parenting and socioemotional adjustment (e.g., higher self-esteem and higher academic self-efficacy) across the two cultural groups. However, perceived maternal authoritarian and training parenting styles were found only to be related to Chinese participants’ adjustment (e.g., higher academic self-efficacy and lower depression). The mediation analyses showed that authoritative parenting significantly mediated the positive associations between the self-development and collectivism goal and socioemotional adjustment for both cultural groups. Additionally, training parenting significantly mediated the positive association between the filial piety goal and young adults’ academic self-efficacy for the Chinese group only. Findings of this study highlight the importance of examining parental socialization goals in cross-cultural parenting research.     

Religious and national group identification in adolescence: A study among three religious groups in Mauritius

Religious group identification is an important but understudied social identity. The present study investigates religious group identification among adolescents of different faiths (Hindu, Muslim, Christian) living in multicultural Mauritius. It further explores how religious and national group identities come together among religious majority and minority adolescents. For three age groups (11 to 19 years, N = 2152) we examined the strength of adolescents’ religious and national group identification, the associations between these two identities, and the relationships to global self‐esteem. Across age and religious group, participants reported stronger identification with their religious group than with the nation. Identification with both categories declined with age, with the exception of Muslims, whose strong religious identification was found across adolescence. The association between religious and national identification was positive, albeit stronger for the majority group of Hindus and for early adolescents. We examined the manner in which religious and national identities come together using a direct self‐identification measure and by combining the separate continuous measures of identification. Four distinct clusters of identification (predominant religious identifiers, dual identifiers, neutrals, and separate individuals) that were differently associated with global self‐esteem were found. Dual identifiers reported the highest level of global self‐esteem. The clusters of identification did not fully correspond to the findings for the direct self‐identification measure. The results are discussed in terms of the meaning of dual identity and the positive manner in which adolescents can manage their multiple identities while taking into account the ideological framework in which those identities are played out.     

Development of Family Therapy in Hong Kong

This paper provides an insight into the development and growth of family therapy in Hong Kong. Family therapy was introduced in Hong Kong in the early 1980s and is now gaining ground. The authors give a historical account of the development of family therapy in Hong Kong, and report on its progress and achievement for the past three decades there. The field has gone through several stages of development. The 1980s were marked by an importation of Western family therapy models, during which overseas expertise was tapped to promote family therapy. The 1990s were characterized by a blossoming of different schools of family therapy on the local scene. Most schools established their own practice centers, and training packages were tailor-made for local use. The 2000s were an important era of family therapy development in Hong Kong. The field has nurtured a new generation of leaders (both academics and front-line practitioners and trainers) who play an essential role in advancing its development. The paper concludes by identifying problems in clinical practice, professional training, and research and knowledge development, and proposes ways of overcoming these difficulties.     

Postnatal exposure to methyl mercury and neuropsychological development in 7-year-old urban inner-city children exposed to lead in the United States

Background: The most common route for general population exposure to methyl mercury (MeHg) is fish consumption. Recommendations to pregnant women about consuming fish contaminated with MeHg are also applied to children, but there are few studies available about the effects of low-level postnatal MeHg exposure in them.

Objectives: To investigate the association between postnatal methyl mercury exposure and neuropsychological development in a study of children also exposed to lead, both measured at 7 years.

Methods: We measured MeHg concentrations in blood samples from the Treatment of Lead-Exposed Children (TLC) trial in which 780 children with elevated concentrations of lead in blood were followed with neuropsychological tests from ages 12–33 months through 7 years. Here we examine blood MeHg concentration and neuropsychological test scores, both measured at age 7 years. We used a maximum likelihood method to estimate geometric mean MeHg concentration and generalized linear regression models to analyze MeHg and neuropsychological test scores.

Results: Geometric mean MeHg concentration was 0.56 (95% confidence interval: 0.52, 0.59) μg/L. A 1 μg/L increase in MeHg was associated with a 2.1 (95% confidence interval: 0.4, 3.8) point increase in Full-Scale IQ and 0.2 (95% confidence interval: 0.02, 0.4) point increase in Learning Slopeindex T-score on a test of verbal memory.

Conclusions: Our results suggest that the relatively low MeHg exposure in US school-aged children from this population has no detectable adverse effect on neuropsychological development. The positive associations observed between MeHg and neurodevelopment may indirectly reflect consumption of beneficial polyunsaturated fatty acids from seafood.
