INTERFACING INFANT MENTAL HEALTH KNOWLEDGE: PERSPECTIVES OF SOUTH AFRICAN SUPERVISORS SUPPORTING LAY MOTHER–INFANT HOME VISITORS

This article is part of a project investigating the interfacing of clinically and research‐generated knowledge in the field of infant mental health (IMH) with local cultural models of child care and development. The article explores the experiences and challenges reported by psychology‐trained supervisors in supervision with local, lay, trained home visitors. Supervisors and supervisees were drawn from two early intervention programs which apply relational IMH mental health models in socioeconomically deprived townships in South Africa. Literature that considers supervisors’ experiences of conducting supervision with lay counselors has been limited, and even more so in settings where there are marked cultural and contextual differences between supervisors and supervisees. These differences pose particular challenges regarding the finding of a shared theoretical understanding of the work as well as to the establishment of a secure working alliance. While it was found that psychoanalytic and attachment‐informed theories of infant development are applicable in these South African settings, differences in race, language, education, socioeconomic status, and culture between supervisors and supervisees challenge the supervisor–supervisee relationship and require psychological processing and creative solutions to ensure integrity in the application of the model.     

DEPLOYMENT STATUS: A DIRECT OR INDIRECT EFFECT ON MOTHER–CHILD ATTACHMENT WITHIN A CANADIAN MILITARY CONTEXT?

Research has suggested that military spouses experience increased depressive symptoms and parenting stress during a military member's deployment. A relationship between maternal depressive symptoms, parenting stress, and child attachment security has been found in the general population, as has an indication that social support may provide a buffering effect. While there appears to be an association between the emotional well‐being of military spouses and child emotional well‐being during deployment, data are limited regarding the association between maternal emotional well‐being and child attachment security. The current study explores the association between deployment status and child attachment to the nonmilitary parent (i.e., the mother in this study) in a sample of 68 Canadian military families. Results revealed a significant impact of deployment status on maternal depressive symptoms and on quality of child attachment. The impact of deployment status on attachment was not mediated through the maternal variables, and despite a main effect of social support on the maternal variables, there was no moderating effect. Thus, our results suggest that deployment may affect child attachment independently of maternal well‐being.     

CAREGIVER SENSITIVITY AND CONSISTENCY AND CHILDREN'S PRIOR FAMILY EXPERIENCE AS CONTEXTS FOR EARLY DEVELOPMENT WITHIN INSTITUTIONS

The current study addressed whether two institution‐wide interventions in St. Petersburg, Russian Federation, that increased caregiver sensitivity (Training Only: TO) or both caregiver sensitivity and consistency (Training plus Structural Changes: T+SC) promoted better socioemotional and cognitive development than did a No Intervention (NoI) institution during the first year of life for children who were placed soon after birth. It also assessed whether having spent less than 9 versus 9 to 36 months with a family prior to institutionalization was related to children's subsequent socioemotional and cognitive development within these three institutions. The Battelle Developmental Inventory (J. Newborg, J.R. Stock, L. Wnek, J. Guidubaldi, & J. Svinicki, 1988) was used to assess the socioemotional and cognitive functioning of children in NoI (n = 95), TO (n = 104), and T+SC (n = 86) at two to three time points during their first 6 to 12 months of residency. Results suggest that improving caregiver sensitivity can improve the cognitive development of infants in the first year of institutionalization whereas improving caregiver consistency in addition to sensitivity is more beneficial for socioemotional development than is sensitivity alone. Similarly, for children in T+SC, longer time with a family prior to institutionalization (consistent caregiver, unknown sensitivity) was associated with better socioemotional, but not cognitive, baseline scores and more rapid cognitive than socioemotional development during institutionalization. These results suggest caregiver sensitivity is more highly related to cognitive development whereas caregiver consistency is more related to socioemotional development in the first years of life.     

老年人整体运动敏感性降低的脑灰质体积变化基础

本研究使用多体素模式分析方法和随机点阵范式,首次探索了老年人整体运动敏感性（GMS）下降和其脑灰质体积下降间的关系。结果发现,老年人GMS显著低于年轻人,老年人V5/MT、V3和额顶等脑区灰质体积显著小于年轻人;V5/MT和V3区的灰质体积信号可以有效预测个体的GMS。结果提示,V5/MT区和V3区,特别是V3区的灰质体积下降可能是老年人GMS下降的主要原因;而基于“去分化假设”,全脑范围内其余脑区的灰质体积下降可能也在一定程度上与老年人GMS下降有关。     

3~5岁幼儿权力概念多重隐喻的认知发展

为考察3~5岁幼儿“权力”概念的大小、垂直空间和重量多重隐喻的认知发展进程, 研究采用了将权力人物和无权力人物图片放置大圆形或小圆形、垂直空间的上方框或下方框和不平衡跷跷板重端或轻端的图片迫选任务。通过3个实验及综合分析发现：3岁幼儿尚不具备权力隐喻理解能力; 4岁是幼儿权力隐喻理解能力的重要发展时期, 具备正极权力概念的隐喻理解能力, 建立起有权力为“大、高、重”的多重隐喻联结; 5岁幼儿的权力隐喻理解能力进一步增强, 已具备较完整的多重隐喻理解能力, 建立起有权力为“大、高、重”、无权力为“小、下、轻”的多重隐喻联结。3~5岁幼儿“权力”概念的大小、垂直空间和重量多重隐喻理解能力同步发展, 不受隐喻靶域习得时间早晚的影响。系列研究表明, 学龄前幼儿的权力隐喻理解能力发展趋势符合隐喻一致性理论, 隐喻表征的产生并非“有或无”的模式, 而是“渐进”呈现发展。     

Leiter-3 generalizability in Scandinavia

The Leiter-3 is a nonverbal assessment that evaluates cognitive abilities and has been adapted for use in Scandinavia. Generalizability of United States-based normative scoring for use with the Scandinavian population was evaluated. Leiter-3 scores from a sample of Scandinavian students were compared with scores obtained from the Leiter-3 standardization sample, controlling for confounding variables, across ages, using mixed-methods analysis. A Scandinavian-population-based sample was created from Leiter-3 standardization data and norms were constructed and were used to generate standardized scores from the sample data. Results suggest that overall the Scandinavian test-takers score higher than American test-takers, but that differences between groups were minimized when controlling for factors that may influence cognitive performance. Creating Scandinavian based scores was not effective at reducing gaps in performance, suggesting that differences in performance between the different populations may be attributable to factors other than those typically controlled for when constructing standardized tests. Implications of these results and recommendations for Leiter-3 adaptation are reviewed.     

Role of serotonin in human aggressive behaviour

This study aimed to evaluate a peripheral serotonergic marker, ³H-imipramine (³H-IMI) binding to platelet membranes, in a group of severely aggressive subjects (A), institutionalized since childhood for mental retardation, as compared with suicide attempters (S) and healthy controls (H). The maximum binding capacity of ³H-IMI to platelet membranes was statistically lower in (A) and (S) than in (H). In addition, a statistically significant difference was observed between the Bmax values of aggressive subjects and those of suicide attempters. No changes in the dissociation constant (Kd) of IMI binding were observed. These data provide further supporting evidence for the hypothesis of an abnormality of the 5HT system in aggressive behaviour and suggest that such an abnormality, as reflected by platelet markers, is more severe in suicide attempters. © 1993 Wiley-Liss, Inc.     

MP3播放器外观设计效果的眼动评估

以大学生为被试,利用眼动法和主观评定法,分析了大学生在评估不同颜色（银白色、红色）、不同外形（椭圆形、圆形、长方体形和四棱柱形）MP3播放器外观设计时的眼动特征。结果发现：对于MP3播放器的外观来说,被试最关注的区域是功能键区域,即就是关注MP3播放器的人机交流功能;对于不同外形的MP3播放器,被试对圆形MP3播放器最感兴趣。
