Children's gender- and age-based categorization in similarity and induction tasks

The present studies examined children's and adults' preferences for gender- or age-based categorization using similarity and inductive inference tasks. Four-year-olds, 6-year-olds, and adults looked at pictures of people and decided which of two was more like a target (similarity condition) or which shared a novel age- or gender-related property with the target (inference condition). Age or gender-based matches were possible. The results are consistent with previous findings that gender-based classification decreases with age. However, they also demonstrate that children use gender more for judging similarity than for making inferences about novel properties. Distinct patterns emerge from the two tasks: 6-year-olds and adults in both conditions categorize more by age than gender; 4-year-olds categorize by gender more than age in the similarity task, but by age more in the induction task. Only adults differentiated by property in the inference condition. These findings suggest that the salience of gender categories cannot entirely be attributed to their inductive potential. Gender has a salience beyond what would be predicted by its power for directing novel generalizations.     

再谈历史心理学

西方心理史学,心态史学和历史心理学的研究目的虽不相同,但都把历史心理现象作为主要研究对象。因此有必要将三者结合创立历史心理学。历史心理学研究历史上个体心理和社会心理及其对历史事件和历史进程的影响。

政府绩效评估与企业绩效评估比较及借鉴意义

政府部门与企业同属社会公共组织,两者的绩效评估具有可比性。政府绩效评估和企业绩效评估可以相互借鉴:政府绩效评估可以借鉴企业绩效评估的评估技术、价值导向、评估方法;政府绩效评估可以引导企业绩效评估关注企业的社会责任。     

Help or hype: Symbolic or behavioral communication during Hurricane Katrina

Public relations professionals increasingly rely on the World Wide Web to communicate with their publics on a variety of issues, including the corporate social responsibility (CSR) efforts the organization has undertaken. In the aftermath of Hurricane Katrina, there is an opportunity to discover how the Best 100 Global Brands used their corporate websites and the power of their brand equity to help the victims of the disaster, as well as to communicate their own CSR efforts. Results show that 51% of these Top 100 firms had messages on their homepages about Hurricane Katrina, and 86% of those firms made donations totaling $105,000,000. The remaining 14% of firms exhibited symbolic communication only, with links to philanthropic organizations aiding rescue efforts.     

Social Support Interventions in Migrant Populations

The phenomenon of immigration has led to an important increasein the number of social programmes and services for migrantpopulations in many European countries. However, some investigationshave shown that the use of formal resources is extremely lowin these groups. In contrast to the limited utilization of programmesand services, research in the field of social psychology hasrevealed that the primary source of help and support for immigrantsis their own informal social network. After analysing the characteristics,advantages and limitations of formal and informal support systems,this paper presents a typology of social support interventionswith migrant populations that integrates both types of support.Four levels are differentiated: dyadic interventions, socialnetwork interventions, mutual aid groups and community interventions.The development of programmes to strengthen the informal supportsystem is emphasized as an alternative to integrating formaland informal resources in social work practice with migrantpopulations.
