符号数量和非符号数量的空间表征:5岁儿童的SNARC效应和距离效应

对物理刺激的数量信息表征是符号数字表征的前提和基础,据此假设在儿童的SNARC效应发生的时序问题上,非符号数量(如面积)的空间表征早于符号数量(如阿拉伯数字)的空间表征。本研究邀请5岁幼儿完成数字比较和面积比较两类任务,结果发现在数字比较任务中没有出现SNARC效应,但却存在距离效应;在面积比较任务中出现了SNARC效应和距离效应。可以推断,在阿拉伯数字的空间表征出现之前,儿童已经能够对非符号数量信息进行空间表征。     

Studies on spontaneous attention to number (SAN) are based on spontaneous focusing on numerosity (SFON)

Li and Baroody presented a study in which they investigate children’ spontaneous attention to exact quantity without acknowledging how previous studies of spontaneous focusing on numerosity (SFON) are related to their concept and methods. The authors’ reaction to our pointing this out makes it is clear that SFON research has had foundational role in the development of Baroody and his colleagues spontaneous attention to number (SAN) idea. Thus the authors must acknowledge the SFON literature as the substantial part of their theoretical and methodological construct. The latest definition of SAN states this undeniably. “SAN is the attentional process that underlies exact number recognition initiated by the mathematical thinking triggered by SFON (e.g., attention to “threeness” directed by conceptual knowledge of “three” activated by SFON).” Furthermore, in their response, Dr Baroody and Dr Li admit that “An awareness of the SFON literature did help us explicitly recognize that, given the ambiguous instructions that do not explicitly direct a child’s attention to number, both the nonverbal production and matching tasks were useful in assessing unguided or spontaneous attention to a number.” It is surprising that in their response to the European Journal of Educational Psychology, the authors maintain their claim that they have cited the SFON literature adequately in their study about SAN.     

The effects of family composition,family health,parenting behavior and environmental stress on children's divorce adjustment

The traditional family composition model of children's divorce adjustment was compared to a family competence model. Subjects included 81 children whose parents remained married, were divorced, or were divorced and subsequently remarried. Divorced families had been separated for between 24 and 48 months. Custodial parents completed questionnaires regarding family functioning, occurrence of stressful life events, and child's psychosocial adjustment. Children completed questionnaires regarding parenting behaviors and self-esteem. A trained examiner conducted a structured diagnostic interview of the child. Multivariate analysis of covariance showed that family composition had a significant effect on the occurrence of stressful events and change in income but not children's adjustment. Hierarchical multiple regression correlations indicated the most powerful predictors of child adjustment were family competence variables which accounted for 21% of the variance in child adjustment scores. In contrast, family composition accounted for only 8% of variance in child adjustment scores. Further, hierarchical multiple regression correlations indicated that higher levels of family functioning were associated with families where parental hostility was low and parents displayed few rejecting behaviors while practicing consistent and appropriate discipline.     

From Social Withdrawal to Social Confidence: Evidence for Possible Pathways

Children born with a possible predisposition toward shyness face many social challenges. Researchers over the past four decades have begun to identify specific factors that influence shy children’s social skill development and their level of peer acceptance. The purpose of this article is to review factors across each developmental stage that have been found to either promote or hinder the development of social competence and peer acceptance in shy children. These factors include physiological differences, caregiver influences, emotion socialization, friendships, general peer support, coping skills, organized social activities, and socioeconomic status.     

不同注意提示线索条件下汉字数字加工的SNARC效应

采用Ponser的实验范式.以判断"壹"到"玖"的汉字数字奇偶为任务,探讨不同提示线索时在注意条件与非注意条件下的空间数字反应编码联合效应(SNARC效应).实验结果发现: (1)当有效提示线索为80%时,注意条件下汉字数字出现了SNARC效应,而非注意条件下对汉字数字的加工没有出现SNARC效应; (2)当有效提示线索为50%时,在注意和非注意条件下汉字数字都出现了明显的SNARC效应.结果表明注意水平对SNARC效应产生了影响.     

Aggressive Children and Effective Communication

Testing a component of a theoretical model which postulates that low levels of communication effectiveness accompany the social and affective problems presented by aggressive children, the study compared the communication skills of a group of aggressive (n = 49) and nonaggressive (n = 49) elementary school children (selected on the basis of teacher ratings) in a structured and cooperative communication task. Based on direct observational measures of communication effectiveness and aggression, and on teacher, peer, and self-rating measures of peer rejection and depressive symptoms, results showed that (a) aggressive children exhibited less effective communication skills and more disruptive communication skills than nonaggressive peers; (b) aggressive children experienced higher levels of peer rejection and depressive symptoms than nonaggressive peers; and (c) group differences in communication effectiveness could not be accounted for by differences in observed aggression and remained significant, even after controlling for differences in peer status and affective functioning. These findings highlight the role that ineffective communication may play in the development and maintenance of aggression and have important theoretical and applied implications, which are briefly discussed. © 1994 Wiley-Liss, Inc.     

Curriculum Evaluation and Assessment of Multicultural Genetic Counselor Education

Multicultural competence in genetic counseling integrates racial-cultural knowledge, awareness, and skills into clinical interventions and research practices. Researchers and educators often cite racial-cultural factors as obstacles for visible racial-cultural people seeking help. However, the professional's unfamiliarity of how his or her own racial-cultural group affiliations are influenced by the history of discrimination and oppression coupled with their lack of self-understanding of racial-cultural issues for him- or herself has also limited the effectiveness of genetic counseling. The purpose of this study is to evaluate the effectiveness of the Handbook of Cross-Cultural Genetic Counseling, a multicultural curriculum developed for genetic counselor education for increasing multicultural counseling competence. The multicultural curriculum was evaluated for its effectiveness of increasing multicultural counseling competence using a nonequivalent control group design. A participant's multicultural counseling competence was hypothesized to increase after being taught the curriculum. The curriculum was effective for increasing multicultural counseling competence. Additionally, achieved multicultural counseling competence was not influenced by when the curriculum was taught. Trend analyses measuring the longitudinal impact of the curriculum on multicultural competence were significant. Implications of the results are discussed.     

童年早期社会能力的发展：一个潜变量增长模型

对119名幼儿进行历时两年的三次追踪测试, 采用潜变量增长建模, 检验童年早期的社会能力是否呈线性增长, 并考察气质、性别、母亲受教育程度及其交互作用对社会能力发展水平与速度的预测作用。结果发现：(1)社会能力在两年中呈线性增长, 起始水平及发展速度均存在显著的个体差异; (2)女孩起始的社会能力水平高于男孩; 母亲受教育程度越高, 儿童起始的社会能力水平就越高; (3)气质节律性对社会能力增长速度的预测因儿童性别而异：节律性能够负向预测女孩社会能力的增长速度、正向预测男孩社会能力的增长速度。     

The Relationship Between Parenting Style and Children's Adjustment: The Parents' Perspective

We examined the relationship between authoritative and authoritarian parenting styles and socio-emotional adjustment in elementary school children as reported from the parents' perspective. Mothers of first through fifth graders provided information about parenting style as well as children's competencies and problem behaviors. Teachers provided ratings of children's adjustment for a subset of the participants. Results indicated that authoritative parenting was associated negatively with parent- and teacher-rated maladaptive behavior, and positively with indicators of healthy adjustment. Correlations between authoritarian parenting and adjustment were either small or non-significant. Regression analyses indicated that authoritative parenting was more predictive of children's competence than maladaptation (22% versus 10% of variance). The effects of parenting style on adjustment were not moderated by demographic variables, such as the child's gender, grade level, ethnicity, and family income.
