Despite ongoing concern about the well-being of HIV-seronegative children living in urban poverty with a seropositive mother, very little is known about this expanding population of children. In this cross-sectional study, the psychosocial adjustment of 60 ethnic minority children 11 to 16 years of age who were living with an HIV-seropositive mother was compared with that of 108 children attending public school in the same community. Results of three multivariate analyses of covariance indicated that, after allowance for differences associated with age, gender, ethnicity, and family structure, the HIV-affected group confirmed (a) greater disturbance in the parent–child relationship, (b) less social support, and (c) greater disturbance in psychological functioning. Secondary analysis of the multivariate findings indicated that the differences were characterized primarily by (a) perception of more indifference and hostility in the mother–child relationship, (b) perception of less social support available from parents, friends, and teachers, and (c) less self-esteem. The findings suggest that HIV infection and concurrent problems may compromise parent–child relationships and perception of social support in ways that leave older, seronegative children living with an infected mother at risk for psychological disturbance. 相似文献

This study assessed the effects of various predictor variables on dimensions of functioning within alcoholic families. Participants were 173 college student volunteers from alcoholic families who completed a measure of family functioning, demographic questions, and questions related to experiences in their families of origin. Child abuse, spousal violence, parental divorce, length of time living with an alcoholic parent, parental marital status, and parental availability and predictability significantly affected family functioning, whereas frequency of parental drinking did not. Results suggest that quality of parental interactions with children is more important for functioning in alcoholic families than frequency of parental drinking. 相似文献

Settler–nationalism is a form of nationalism that must face specific cultural dilemmas as a result of the dispossession of indigenous peoples. Since the Second World War, Australia has attempted to come to terms with its past of dispossession and to find ways to incorporate Aborigines within national imaginings, and within the nation itself. This paper argues that there are two modes of settler–nationalism—termed assimilationist and indigenizing—that compete to organize the national reality, including relations between the settler and indigenous populations. Kleinian object relations theory is drawn upon to delineate the emotional structures of the two modes of nationalism. Implications for indigenous rights, in particular for Aboriginal land rights, are examined. 相似文献

文章探讨了儿童知觉期望的教师领导行为与儿童同伴关系之间的关系.研究选取北京市某小学4、6年级学生作为被试,共180名(男100名,女80名).采用社会计量法测量儿童的同伴关系,教师领导行为问卷测量儿童知觉的和期望的教师领导行为.主要的结果如下:(1)知觉到放任型领导不利于儿童同伴关系的发展,而知觉到民主型与权威型领导对儿童的同伴关系影响不大;(2)知觉到权威型领导有利于形成一个有凝集力的班级团体,知觉到民主型领导行为有利于班级团体的调和. 相似文献

采用人工材料,比较类别标签、特征相似性与因果关系对归纳推理强度的影响。包括两个实验,实验1比较类别标签与特征相似性对归纳推理的影响,结果表明,当类别标签对归纳推理的影响显著强于特征相似性时,不能将类别标签等同于一个相似性特征。实验2进一步探讨类别标签与因果关系对归纳推理的作用,结果表明,因果关系作用明显强于类别标签的作用。综合两个实验的结果并整合前人相关研究,提出了不同关系影响归纳推理的强度假想。 相似文献

Two studies extended psychometric research on the Student–Teacher Relationship Scale (STRS) with kindergarten and preschool children (N1 = 60–71; N2 = 35) and their teachers. These studies used a multi‐method approach to replicate and extend previous findings concerning the convergent validity of the STRS Closeness, Conflict, and Dependency scale and to further examine the discriminant validity of the STRS. Study 1 investigated convergence between the STRS scales and child‐ and peer‐reports of the same constructs based on a multi‐trait multi‐method approach. Study 2 examined the pattern of associations between the STRS and indicators of teacher–child relationship quality rated by external observers. Support was found for the convergent validity and to a lesser extent the discriminant validity of the STRS Closeness and Conflict scale. For the STRS Dependency scale, additional research remains necessary. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The purpose of the current study was to compare the delivery of varied versus constant high‐, medium‐, and low‐preference stimuli on performance of 2 adults on a computer‐based task in an analogue employment setting. For both participants, constant delivery of the high‐preference stimulus produced the greatest increases in performance over baseline; the varied presentation produced performance comparable to constant delivery of medium‐preference stimuli. Results are discussed in terms of their implications for the selection and delivery of stimuli as part of employee performance‐improvement programs in the field of organizational behavior management. 相似文献

One 9‐year‐old child was taught conditional discriminations between dictated names in Spanish and their corresponding pictures across three stimulus sets while her 10‐year‐old brother observed. Posttests revealed the emergence of symmetry relations in the form of oral naming skills by both children. 相似文献

The present study examined involvement in children's learning among parents of 101 children between 8 and 12 years of age (53 parents of children with ADHD, 48 parents of children without ADHD). Compared to parents of children without ADHD, parents of children with ADHD reported lower self-efficacy in their ability to help their children, felt less welcome and supported by their children's schools and teachers, and perceived less time and energy for involvement in their children's academic lives. Mothers of children with and without ADHD reported similar types and levels of involvement behaviors in the home. Fathers of children with ADHD reported being more disengaged from their children's learning and using more coercive and punitive interactions regarding their children's achievement compared to fathers of children without ADHD. These findings underscore the difficulties in parent-supported learning practices and home-school collaboration initiatives faced by parents of children with ADHD and educators alike. Implications for school psychology practice are discussed. 相似文献

The determinants of generalized imitation of manual gestures were investigated in 1‐ to 2‐year‐old infants. Eleven infants were first trained eight baseline matching relations; then, four novel gestures that the infants did not match in probe trials were selected as target behaviors. Next, in a generalized imitation test in which matching responses to baseline models were intermittently reinforced, but matching responses to target models were not eligible for reinforcement, the infants matched baseline models but not the majority of their target behaviors. To ensure their failure to match the target behaviors was not due to motor constraints, the infants were trained, in a multiple‐baseline procedure, to produce the target responses under stimulus control that did not include an antecedent model of the target behavior. There was no evidence of generalized imitation in subsequent tests. When the infants were next trained to match each target behavior to criterion (tested in extinction) in a multiple‐baseline‐across‐behaviors procedure, only 2 infants continued to match all their targets in subsequent tests; the remaining infants matched only some of them. Seven infants were next given mixed matching training with the target behaviors to criterion (tested in extinction); they subsequently matched these targets without reinforcement when interspersed with trials on which matching responses to baseline models were intermittently reinforced. In repeat tests, administered at 3‐week intervals, these 7 children (and 2 that did not take part in mixed matching training) continued to match most of their target behaviors. The results support a trained matching account, but provide no evidence of generalized imitation, in 1‐ to 2‐year‐old infants. 相似文献
