Evidence for altered configural body processing in women at risk of disorders characterized by body image disturbance

Two studies were conducted to assess appearance-related visual processing mechanisms in populations at risk of disorders characterized by body image disturbance. Using inverted stimuli, Experiment 1 assessed visual processing mechanisms associated with body, face, and house viewing in adolescents. Experiment 2 applied the same protocol to assess appearance-related configural processing in high- and low-risk adolescent women, and women recovering from disorders characterized by body image disturbance. Experiment 1 found evidence for typical configural face and body processing, although adolescent women reported higher levels of body image concern (BIC) and self-objectified to a greater extent than adolescent men. In Experiment 2, typical body inversion effects were seen in the low-risk group, whilst there was some evidence to suggest a disruption to the configural processing of body stimuli in high-risk adolescents and in women recovering from body image disorders. Women in recovery were also quicker to respond to all stimuli, whilst high-risk adolescents took longer to respond to bodies than to other stimuli. Configural face processing was intact in all groups, and effects did not directly relate to BIC or self-objectification. These findings have implications for future research looking to inform early interventions and treatment, suggesting that there could be a tendency to visually process individual body parts at the expense of the whole-body form in women at risk of developing body image disorders, as well as those in recovery.     

Hair sampling for cortisol analysis with mother-toddler dyads living in low-income homes

BackgroundA first step to advance stress science research in young children is understanding the relationship between chronic stress in a mother and chronic stress in her child. One non-invasive measure of chronic stress is hair cortisol. However, little is known about strategies for hair sampling in mother-toddler dyads living in low-income homes in the U.S. To address prior limitations, the purpose of this study was to understand the feasibility of sampling hair for cortisol analysis in mother-toddler dyads living in low-income homes in the U.S. We examined feasibility related to participation, eligibility, and gathering an adequate hair sample weight.MethodsWe approached 142 low-income, racially diverse, urban-dwelling mothers who were participating in an ongoing longitudinal birth cohort study for informed consent to cut approximately 150 hairs from the posterior vertex of their scalp and their toddlers’ (20–24 months) scalp. We demonstrated the process of sampling hair with a hairstyling doll during home visits to the mother and toddler using rounded-end thinning shears.ResultsOverall, 94 of 142 mother-toddler dyads (66 %) participated in hair sampling. The most common reason for participation refusal was related to hairstyle. All but three hair samples were of adequate weight for cortisol extraction.DiscussionThe findings from this study can help researchers address sampling feasibility concerns in hair for cortisol analysis research in mother-toddler dyads living in low-income homes in the U.S.     

Cognitive complexity of social images revealed by Jewish Israeli adolescents relating to drawings of Jews and Arabs

The present study examined age‐related differences among Israeli youth regarding the complexity of their mental images of Jews and Arabs, two groups that are adversaries in the Middle East conflict. The participants, 494 Jewish children and adolescents ranging from 8–16 years old each, drew two human figures, one Jewish and one Arab, and then attributed a forename and a profession to each drawn image. Four complexity variables were scored as follows: image complexity (number of items included in the figure), embellishments (number of items added to the drawing and in the space around the figure), image name, and image profession. Overall, participants depicted members of their in‐group as more complex. However, early adolescence was found to be a critical age at which differences emerged. The findings suggest that introducing complexity to social representations in early adolescence may facilitate prevention of negative associations related to outgroups and enhance intervention to reduce stereotypes, prejudice, and racism.     

Prevalence and factors associated with turn signal neglect-related crashes among motorcyclists and car drivers in Vietnam

Road traffic crashes and injuries are a major societal challenge around the world. However, the majority of injuries and fatalities occur disproportionately in low-income and medium-income countries. Previous studies have concluded that risky behaviours were the main contributing factor of traffic crashes. Turn signal neglect (TSN) when making a turn is one of those risky behaviours. Unfortunately, research on TSN has been very limited. This study investigates the prevalence of TSN-related crashes and factors affecting TSN among motorcyclists and car drivers. Data was obtained from self-administered questionnaires conducted in Vietnam. The findings showed that 17.54% of motorcyclists and 14.76% of car drivers have experienced at least one crash caused by their failure to turn signals in the last three years. Additionally, fewer years having a riding/driving license, longer daily travelling time, lower frequency of turn signal use, and having received a fine due to TSN were found to be positively associated with TSN-related crashes for both motorcyclists and car drivers. The findings highlight the importance of TSN for road safety and the need for authorities to develop more effective educational strategies and to increase traffic law enforcement.

消极身体意象是青少年健康成长所面临的重要问题之一。了解消极身体意象对青少年的危害以及其形成的影响因素, 对于青少年群体身心健康发展具有重要意义。消极身体意象对青少年的负面影响主要包括自我概念、情绪体验、体重控制策略、饮食失调和社会生活五个方面; 并且青少年消极身体意象形成的影响因素主要有生物因素(BMI)、社会文化因素(父母、同伴和大众媒体)和心理因素(人格因素、认知方式)。未来可从以下几个方面进一步深入研究：(1) 基于生物-心理-社会模型的视角完善青少年身体意象发展的理论模型; (2) 考察社交媒体等新兴因素的作用; (3) 阐明青少年在加工身体相关信息时的认知特点; (4) 推进中国青少年消极身体意象本土化研究。     

父母冲突频率与青少年生活满意度的关系：青少年行为反应的中介作用

父母冲突与青少年的身心健康息息相关。本研究以366名青少年为被试,采用问卷调查法研究父母冲突频率与青少年生活满意度间的关系,以及父母冲突时青少年行为反应在其中的中介作用。结果表明：（1）父母冲突频率显著负向预测青少年生活满意度;（2）青少年的介入行为与生活满意度呈显著正相关,回避行为则与生活满意度呈显著负相关;（3）在主张–回避的父母冲突场景中,青少年的回避行为在父母冲突频率与生活满意度间起到部分中介作用,中介效应占总效应的22.90%。     

Effects of models and demonstrations of personal narratives on the use of lexical ties by writers with mental retardation

A single subject reversal design was used to investigate the effects of two methods for teaching writing to eight adolescents with mild or moderate mental retardation during a weekly process writing workshop. During each workshop, each student wrote a personal narrative while the teacher circulated among the group and provided positive verbal feedback and spelled words on request. Students' texts were later typed with corrected spelling and punctuation and returned to them with verbal praise before the next writing workshop. During the first experimental condition, the subjects listened to an exemplar text selected by the teacher. In the second phase, the teacher read a narrative she had written as the exemplar text. During the third experimental condition, the teacher orally self-instructed herself through steps in writing a narrative. The subjects' texts were analyzed for number of words written and number and type of lexical ties used to produce cohesion between sentences in a text. The model narrative produced the best gains in the number of words written by the poorer readers, while the demonstration improved the cohesiveness of their texts. The better readers and writers wrote more cohesively during the model narrative and produced longer text during the demonstration condition.     

Influence de la composition de la fratrie sur les pratiques éducatives parentales déclarées et sur la représentation de l'éducation chez les préadolescents

The aim of our study is to analyze the influence of the make up of the siblings on the parents' educational practices and also on the meaning of education to preadolescents. The results gathered from a sample of 88 preadolescents and their mothers show a difference of parental educational practices according to the make up of the siblings (relaxation of the practices with the youngest). The study of the meaning of education to preadolescents shows that only children are the most in accordance with their mothers. Children from large families imagine a future education further from mothers' educational practices.     

Study on the relations between temperament,aggression, and anger in children

The present work analyzes the relationships between the dimensions of temperament and the exteriorized emotions of aggression and anger. Temperament was assessed by mothers using the Dimensions of Temperament Survey‐Revised, while aggression and anger were self‐reported by the children using the Scale of physical and Verbal Aggression and the State–Trait Anger Expression Inventory for Children. The sample studied was made up of 293 children (49.83% boys; 50.17% girls) with a mean age of 11.13 years. The results showed that temperamental difficulties give rise to exteriorized emotions, especially anger. Predictive values of temperament on aggression and anger ranged from 1% to 7% of explained variance. Aggr. Behav. 32:207–215, 2006. © 2006 Wiley‐Liss, Inc.     

青少年外向/宜人性人格、互联网服务偏好与"网络成瘾"的关系

该研究采用问卷法,以481名中学生为被试,通过无约束结构方程模型分析方法探讨了外向性、宜人性人格特征与互联网服务偏好的交互作用对网络成瘾的影响。研究发现在对网络成瘾的影响上,青少年宜人性人格特征与互联网社交服务偏好存在显著的交互作用,但与互联网娱乐、信息和交易服务偏好的交互作用不显著。外向性人格特征与互联服务偏好不存在显著的交互作用。(1)从平均影响来看,外向性、宜人性、互联网社交、娱乐和交易使用偏好能够正向预测网络成瘾,互联网信息使用偏好对网络成瘾没有显著的预测效果;(2)在宜人性高分组中,互联网社交服务偏好与PIU的正向关系要强于宜人性低分组。斜率检验表明对于低宜人性人格的青少年来说,互联网社交服务偏好不易导致其成瘾,而对高宜人性人格的青少年而言,互联网社交服务偏好反而容易导致其成瘾。
