Age trends in stimulus overselectivity

Stimulus overselectivity refers to the phenomenon whereby stimulus control over behavior is exerted only by a limited subset of the total number of stimuli present during discrimination learning. It often is displayed by individuals with autistic spectrum disorders or learning disabilities, but is not exclusive to those groups. The present studies investigated the impact of aging on stimulus control and overselectivity. Three age groups--18-22, 47-55, and 70-80 year olds-were studied in two experiments. All participants were trained on a simple discrimination task, randomly assigned to one of two conditions (either with or without a distractor task), and then tested for the emergence of overselectivity (Experiment 1). In Experiment 2 responding controlled by the overselected stimulus elements was reduced by introducing a verbal punisher. In subsequent tests, control of behavior by the previously underselected elements from Experiment 1 was enhanced across the two younger age groups but not the oldest group of participants. The results are discussed in relation to the attention-deficit and overshadowing accounts of overselectivity.     

Relationships matter in personality development: evidence from an 8-year longitudinal study across young adulthood

Personality-relationship transactions were investigated in a general population sample of young German adults with three assessments over 8 years. Four general findings were obtained. First, personality development was characterized by substantive individual differences in change. Second, bivariate latent growth models indicated that individual differences in personality change were substantially associated with change in peer and family relationships. Third, forming a partner relationship for the first time moderated the maturation of personality. This finding was replicated over two subsequent time intervals with independent subgroups. Fourth, higher neuroticism and higher sociability predicted which of the singles began a partner relationship during the next 8 years. The results confirm that individual differences in personality development predict and result from life transitions and relationship experiences.     

大学生对年轻人和老年人的年龄刻板印象

采用内隐联想测验(IAT)和相应的外显测量,考察了大学生被试对年轻人和老年人的内隐和外显年龄刻板印象。结果表明:大学生被试在身体特征、个人表达和认知能力等3个方面对老年人都普遍存在明显消极的内隐态度;而在外显测量中,对年轻人和老年人的态度不存在显著差异;内隐和外显的年龄刻板印象测量之间相关不显著,可以用不同的记忆系统理论和联结-命题评价(APE)模型来解释内隐和外显测量不一致现象;不同性别的大学生被试在外显态度测量和内隐联想测验中测得的年龄刻板印象均不存在显著差异。     

Young mothers' play with their toddlers: individual variability as a function of psychosocial factors

There is no one style of parenting which characterizes young mothers as a group. In addition, life circumstances play an important role in shaping maternal behaviour. The aim of this study was to identify patterns of maternal play behaviour and contextual (social and personal) factors associated with these different patterns. In this study, 107 young mothers were observed at home during play with their toddlers; maternal behaviour was coded for joint attention (shared focus of mother and toddler attention) and emotional availability (e.g. sensitivity, intrusiveness, hostility). Mothers reported on aspects of their childhood history and current personal functioning and social support. A person‐centred analytic approach, using cluster analysis, revealed three distinct groups of maternal play behaviour: (1) ‘sensitive‐engaged’ (2) ‘inconsistent‐directive,’ and (3) ‘intrusive‐prohibitive’. Multivariate analyses revealed that contextual factors in mothers' lives (e.g. childhood abuse, depressive symptomatology, partner violence, social support, and parenting self‐confidence) were differentially associated with parenting clusters.

Trustworthiness,friendships and self‐control: factors that contribute to young children's school adjustment

The aim of present study was to examine the relationship between young children's peer‐reported trustworthiness and their school adjustment. Two hundred and eleven (103 male and 108 female) children in the United Kingdom (mean age = 6 years 2 months) took part in this study. Measures of peer‐reported trustworthiness, child‐rated school adjustment, and teacher‐rated school adjustment were administered twice across a one‐year period. Also, children's number of friendships, peer acceptance, and self‐control were assessed at Time 2. Multisample path analyses were conducted separately by sex. For both samples there were direct longitudinal paths between peer‐reported trustworthiness and changes in teacher‐rated school adjustment. For boys, the longitudinal path between peer‐reported trustworthiness and changes in child‐rated loneliness was mediated by peer acceptance, and peer‐reported trustworthiness mediated the relationship between self‐control and teacher‐rated school adjustment. Sex differences in peer‐reported trustworthiness also emerged: girls were rated as more trustworthy by their peers than were boys. The findings support the hypothesis that young children's trustworthiness contributes to school adjustment, which is due in part to peer acceptance. Copyright © 2007 John Wiley & Sons, Ltd.     

Abuse Experiences in a Community Sample of Young Adults: Relations with Psychiatric Disorders, Sexual Risk Behaviors, and Sexually Transmitted Diseases

This study documents significant associations among lifetime abuse experiences, psychiatric diagnoses, and sexual risk behaviors in a multiethnic community sample of young men and women (N = 1803) in South Florida. Self-report data were collected via structured interviews as part of a longitudinal follow-up of a larger school-based study. Participants were grouped according to extent of lifetime abuse experiences. Cumulative lifetime abuse experiences were associated with increased risk for a broad range of individual lifetime psychiatric disorders, as well as cumulative lifetime psychiatric disorders. Both cumulative abuse experiences and cumulative psychiatric disorders were independently associated with (a) higher levels of sexual risk behaviors and (b) higher risk for lifetime sexually transmitted diseases (STDs). Implications for selective prevention of sexual risk behaviors and STDs among young adults with histories of abuse and psychiatric disorders are discussed.     

"马克思与我们同行"

中国80多年的马克思主义,先后形成了“阶级斗争”和“生产力论”两大解读马克思主义的主要话语。这在一定意义上造成了对马克思主义理解的片面性。马克思理论的突出品格是社会批判和反对教条主义,其价值追求则是通过批判市场,消除经济暴政去达到“人类解放”。中国正在步入“马克思的问题域”,拒绝马克思就等于从一个方面拒绝吸取矫正市场经济发展的思想资源。     

Between Dream Cities and Reality: Personal Narratives of Ex-Soviets in Israel

Domestication of space is a major problem for migrants, particularly when they settle in a geographically remote country with a markedly different climate and culture. This paper analyzes attitudes to city life in the country of origin and in the new homeland in personal narratives of immigrants to Israel from the countries of the former Soviet Union. The material was drawn from in-depth unstructured interviews conducted in 1999–2002 and 2005–2006, and Israeli Russian-language Internet forums. Soviet Jews were predominantly city dwellers, and their immigration stories are permeated with explicit and tacit comparisons of the space of the two countries. The cities of origin are idealized, and their image has disintegrated into hospitable and warm cities of pre-emigration life on the one hand, and unfamiliar, alien cities of post-Soviet period on the other. In Israel many ex-Soviets chose to live in the so-called development towns. Attracted by relatively inexpensive apartments, the newcomers found themselves trapped in places where jobs are scarce and the quality of life has been recently dropping. In reflecting on various towns, interviewees focus on physical and symbolic dimensions, the most frequent being: big–small, center–periphery, exposed–protected, and powerful–weak. In contemporary Russian culture center is associated with job opportunities and entertainment, with high social status and good quality of life. In Israel the opposition center–periphery has retained its significance, yet the whole country is considered by many immigrants as deeply provincial, cut off from the rest of the world and devoid of opportunity for the young, the conviction that is supported by publications in the Russian-language media.

Making a Political Statement or Refusing to Grow Up—Reflections on the Situation of the Academic Youth in Postwar British Literature

The author attempts to apply the psychoanalytic concept of “prolonged adolescence” to two literary works, both of which are embedded in England’s postwar social and political climate. The discussion of John Wain’s Hurry on Down ([1953] 1979) and John Osborne’s Look Back in Anger ([1956] 1989), by necessity, involves a look at those factors responsible for shaping the cultural “mood” in those days. However, the author’s primary concern lies with how two particular (fictional) individuals, or antiheroes, deal with the frustration, which, although generally felt among contemporary academia, in their cases seems to hide a much deeper layer of mental insecurity and instability. In fact, we come to feel that the characters have not achieved a proper sense of identity (“self”) and are, from the point of view of maturity, delayed and, hence, “unfitted” to cope adequately with the external world. Having long achieved formal adulthood, they seem to have gotten “stuck” somewhere along the passage of growing up. Essential papers by Sigmund Freud and his daughter Anna, as well as a very early paper on the topic by Siegfried Bernfeld, are, among others, taken into account, as is the profound research done by Peter Blos on the subject in question.
