正念研究的分歧：概念与测量

正念是当代临床健康心理学领域出现的一个新概念, 尽管其应用在临床领域取得了瞩目的成绩, 但对于正念的理论研究却亟待加强。在对正念的三阶段概念演进过程及四种取向的测量工具进行了系统梳理与评价后, 发现目前对正念的理论研究存在两大问题。一是概念不够清晰, 它可以指代一种行为(冥想)、心理状态、心理过程, 甚至是一种人格或类人格特质; 二是测量过于多元, 有状态取向、能力取向、认知取向和特质取向。两大问题的核心在于如何理解正念。基于对问题的分析及以往实证研究, 建议可以借鉴价值实践分类体系(Values In Action Classification), 以类特质为取向, 采用兼顾文化共同性和特殊性的方法, 深入挖掘其独特的核心内涵, 在命名、测量上突显个体对当下经验留心的基本特点。     

Conceptions of aggression and withdrawal in early childhood

Two studies investigate young children's beliefs about aggression and withdrawal in others with reference to the possibility of stability and change. Study 1 (N=41) provides evidence that preschool children (1) view aggression in more essentialist ways (i.e. they believe it to be more stable and less changeable) than withdrawal and (2) believe that friends hold a greater potential to create change in aggression and withdrawal than do other potential sources of influence, such as parents and teachers. Study 2 (N=25) replicates the findings of Study 1 and also demonstrates that by preschool age, children hold systematic ideas about the effectiveness of strategies that friends can use to change the behaviour of their peers. These ideas include the belief that prosocial strategies, such as showing peers how to make friends, are more effective than requests to stop engaging in undesirable behaviour. Study 2 also demonstrates that preschool‐aged participants engaged in essentialist reasoning to a greater extent than did a comparison group of 20 7–8 year olds.

刻板印象与特质建构关系的实验研究

根据平行-约束-满足模型的基本主张,利用情境模拟法探讨了特质激活与刻板印象的建构关系以及刻板化信息与个体化信息经由特质激活所表现出的交互影响。实验结果表明：(1)刻板印象影响特质的含义,特质会自动化地激活刻板印象,并且由特质及其具体的描述性内容所形成的个体化信息在具体的情景中联合起来影响刻板印象效应;(2)刻板印象与其他信息在加工通路上是相对独立或平行的;(3)刻板印象是兼具自动化加工与控制加工的混合体。     

Effects of viewing videos of bullfights on Spanish children

Some of the psychological effects of viewing bullfights on children 8–12 years old are described. Two hundred and forty subjects (120 girls and 120 boys) aged between eight and twelve from a variety of socioeconomic backgrounds were selected from three public or private elementary / secondary schools in Madrid, Spain. The first study used a questionnaire to examine the children's attitudes towards bullfighting by looking at their acceptance and cognitive‐emotional appraisal of the event. Videotapes of bullfights with differing commentaries were then used, along with a battery of questionnaires, to assess the emotional impact of these events, as well as the impact of narrative explanations on aggression and anxiety. Most children were not very positive about bullfights in the initial questionnaire. Viewing of tapes with ‘festive’ or aggressive dialogues (but not tapes without a justification) resulted in more expressed aggression in boys than girls. There was also evidence that age had a significant effect, and that some children appeared disturbed by the exposure. Aggr. Behav. 30:16–28, 2004. © 2004 Wiley‐Liss, Inc.     

Concurrent and prospective effects of multi‐dimensional aggression and anger on adolescent alcohol use

This study examined the relationship between alcohol, anger, and aggression in high school students. Anger and three types of aggressive expression (verbal, physical toward people, and physical toward objects) were evaluated cross‐sectionally and prospectively, via structural equation modeling for relationships to alcohol use in Mexican American and white non‐Latino 9–10th (Time 1) and 11–12th grade (Time 2) students. At both times cross‐sectionally, anger and aggressive anger expression tended to correlate positively with alcohol use in each ethnicity/gender group. However, prospectively, aggressive forms of anger expression tended not to be related to alcohol use two years later. Only verbally aggressive anger expression was related to alcohol use two years later and then, only for Mexican American and white non‐Latino females. There was, therefore, little basis for causal links between aggressive anger expression and alcohol use in a general population of high school students. Aggress.

Different forms of aggression among inner-city African-American children: Gender, configurations, and school social networks

Using narrative reports of peer conflicts among a sample of African-American children and adolescents from inner-city schools, this study investigated the development and social functions of four types of aggressive behaviors: social, direct relational, physical, and verbal aggression. A total of 489 participants in grades 1, 4, and 7 were interviewed (220 boys and 269 girls). Results showed that low levels of social aggression and high levels of physical aggression were reported in peer conflicts. Gender differences on social, direct relational, and physical aggression were primarily observed in the comparisons of same-gender conflicts at grade 7. Distinct configurations were identified across different forms of aggression. Boys with configurations of physical and/or verbal aggression had higher levels of school social network centrality than non-aggressive boys. Girls with configurations of social and/or direct relational aggression showed relatively higher levels of network centrality than non-aggressive girls.     

Replicated Findings and Future Directions for Intergenerational Studies: Closing Comments

This commentary summarizes findings from four papers that set out to replicate, albeit not with identical measures or sampling criteria, research on several questions in the multigenerational study of antisocial behavior by children and child-rearing strategies by parents. The weight of the evidence from our studies indicates some degree of intergenerational continuity in behavior. We observed that adjacent generations G1 and G2 are similar with respect to their styles of parenting and that adjacent generations G2 and G3 are similar with respect to antisocial behavior. In addition, the G2 parent's parenting style plays an important role in mediating or transferring the risk of antisocial behavior across the generations. Implications and directions for future research are discussed.     

Sport team identification and willingness to consider anonymous acts of hostile aggression

Previous research indicated that a sizeable minority of individuals report a willingness to consider engaging in anonymous acts of instrumental aggression directed toward players and coaches of a rival team. Individuals with a high degree of identification with their favorite team were particularly likely to consider such acts. The current investigation was designed to extend this research by examining the likelihood that individuals would consider engaging in hostile anonymous aggression. It was expected that highly identified persons would be particularly likely to consider these acts, even though the acts would not provide a competitive advantage for their team. Data collected from 175 university students confirmed the expectations. In addition, the results indicated that males were more likely than females to report a willingness to consider the hostile aggressive acts and that participants were more likely to report a willingness to engage in less destructive acts (e.g., tripping an opposing player or coach) than more destructive acts (e.g., murdering an opposing player or coach).

Strain‐specific aggressive behavior of male mice submitted to different husbandry procedures

Severe aggression within groups of male laboratory mice can cause serious welfare problems. Previous experiments have shown that the transfer of specific olfactory cues during cage cleaning and the provision of nesting material decrease aggression and stress in group‐housed male mice. In this study, the combined effect of these husbandry procedures was tested for their long‐term effect on aggression in two strains of male mice (BALB/c and CD‐1). We used postcleaning aggressive behavior, wound counts, and testosterone levels as indicators of aggressiveness. Physiological responses to social challenge were investigated through urinary corticosterone and adrenal tyrosine‐hydroxylase measurements. Furthermore, the aggression‐modulating effects of two enrichment items (ShepherdShack/DesRes and PVC tube) were explored. Marked differences were found between the two strains. CD‐1 mice were more aggressive, had higher testosterone levels but lower corticosterone levels, and had fewer wounds than BALB/c mice. However, in neither of the two strains was long‐term enrichment with nesting material and its transfer after cage cleaning effective in lasting reduction of intermale aggression. This may be explained by the fact that aggression levels were generally low. It seems that housing mice in small, socially stable groups or keeping social disturbances to a minimum considerably modulates aggression in group‐housed male mice. Mice of both strains housed in cages enriched with nesting material had lower urinary corticosterone levels than standard‐housed mice. We therefore conclude that the long‐term provision of nesting material, including the transfer of nesting material during cage cleaning, may enhance the welfare of laboratory mice. Aggr.

Sex differences in genetic and environmental effects on aggression

The aim of the present study was to investigate the genetic and environmental factors influencing teacher and parental rated aggression in boys and girls, asking whether the magnitude of these effects is similar across rater and sex. The study is part of an ongoing nationwide twin‐family study of behavioral development and health habits carried out in Finland. The sample consisted of 1651 twin pairs (264 monozygotic male, 300 monozygotic female, 292 dizygotic male, 278 dizygotic female, and 517 dizygotic opposite‐sex twin pairs), representing subsets of five 11‐ to 12‐year‐old twin cohorts (b. 1983–1987). The data were collected using the teacher and parental rating forms of the Multidimensional Peer Nomination Inventory. Structural equation models of sex‐limitation assessed sex differences in genetic and environmental influences on aggression. The results suggested significant genetic, common environmental, and specific environmental effects on aggression in both boys and girls, but the best fitting model differed depending on the informant. For both ratings, boys showed lower levels of heritability and higher levels of common environment than girls. In addition, the teacher rating data also suggested the presence of either sex‐specific common environmental effects or sex‐specific genetic effects. Support is provided also for sibling contrast effects, either at the behavioral level or as a rater bias. Aggr. Behav. 29:55–68, 2003. © 2003 Wiley‐Liss, Inc.
