Song recognition in zebra finches: Are there sensitive periods for song memorization?

Male zebra finches learn to sing songs that they hear between 25 and 65 days of age, the sensitive period for song learning. In this experiment, male and female zebra finches were exposed to zebra finch songs either before (n = 9) or during (n = 4) the sensitive period. Following song exposure, recognition memory for the songs was assessed with an operant discrimination between familiar and novel songs. Zebra finches that were exposed to songs between 22 and 30 days of age discriminated between familiar and novel songs; zebra finches exposed to songs from 9 to 17 days of age did not. Failure to memorize songs heard prior to the sensitive period may contribute to the exclusion of those songs from the repertoire of songbirds.     

Developing and Improving After-School Programs to Enhance Youth’s Personal Growth and Adjustment: A Special Issue of AJCP

Participating in after-school programs (ASPs) has become a common experience for children. This special issue provides a perspective on the current status of research on ASPs. This introductory article overviews the historical and current context of ASPs and then describes a developmental ecological model to guide research in this area. The model offers a framework from which to organize and synthesize the research presented in this issue. Key principles include a holistic view of development that recognizes interrelations between multiple domains of youth adjustment, attention to multiple, relevant factors within and outside of youth that affect development, examining the dynamic interplay between persons, program features, and other contexts over time, and understanding the active role of youth in affecting their own development. These principles are examined in relation to five main areas: youth characteristics, social ecologies, program features, participation, and short- and long-term outcomes. Recommendations for future research are discussed.     

Advancing a Community Psychology of Men

This commentary reviews and integrates several themes described in this special issue on men. Social forces of the past and present such as colonialism and hegemonic masculinity are noted as a continuing influence on men’s social roles, as are the social-justice movements that contribute to the liberation of women and sexual minorities. The early sections of the commentary examine the studies in the context of these forces and movements, emphasizing how men both resist and accept traditional masculinities. In the latter sections the commentary turns to the research process –first with a discussion of the structural and constructionist themes in the studies, followed by the issue of how men are classified (implicitly or otherwise) as either agents or targets of oppression. The implications of these for community psychology research with men are considered, along with the idea that research is a social “performance” in which a researcher’s concern about her or his audience influence the research process. The conclusion summarizes the challenges of conducting research with men while making the case that community psychology offers some distinct advantages in managing them. Of particular value is the field’s emphasis on diversity, social justice, and social ecology.     

“多少”概念发展的研究

采用数量判定任务,分别用2～30和5～100范围内点子图为刺激,研究个体“多”和“少”概念的发展。结果发现：在5～100点子条件下,随年龄的增长,个体“多”概念的判断值、“少”概念的判断值、“多”“少”概念的临界值均显著增大;7～9岁是个体“多少”概念发展的转折期;个体对“多少”概念的认知具有相对性;在本实验的两种条件下,随年龄增长,个体“多”概念的判断值、“少”概念的判断值、“多”“少”概念的临界值逐渐趋于刺激点子数最大值的2/3、1/3、1/2,“多”概念与“少”概念判断的不确定距离逐渐趋于刺激点子数最大变化范围的1/3或略小于1/3。     

Quality of Life in the European Union and the United States of America: Evidence from Comprehensive Indices

The main question of this article is about the quality of life in the European Union and the United States measured by different comprehensive indicators (HDI, WBI, WISP, OLS, PWI, ABS, HLE). On the world scale moderately different levels of quality of life characterize the European Area and the US. In objective terms, the US is more at the top level regarding economy and science, whereas Europe is more at the top level regarding social concerns in a broad sense. In subjective terms, which means to rely on the usual subjective measures, the average of US population seems to be slightly better off than the average of the EU population. That said, the differences inside the EU are often more significant than those between the EU and the US. Many EU countries in Northern and Western Europe show higher satisfaction levels than the US, and Eastern Europe is especially low in respect to the satisfaction of its population. It is rather obvious that the choice of criteria and values influences the results of the comparisons of nations and supranational unions to a considerable degree.

Imaginaries of Development: The Rockefeller Foundation and Rice Research

This article is both a historical and contemporary analysis of the Rockefeller Foundation's changing role in rice research over the past 50 years, and though there are many overlaps between them, focuses on three broad periods: first, the RF's early work in rice research, particularly through the establishment of the International Rice Research Institute (IRRI) and the Green Revolution era of the 1960s and 1970s; second, the development of the RF's rice biotechnology program in the 1980s; and third, the RF's focus on agricultural research in Africa, with rice research as a subset of their programmatic efforts, during the 1990s and beyond. Rice research in each of the different periods was driven by different framings of problems and potential solutions, incorporating wider ideologies, epistemologies, and key actors and networks, with the RF at the center. Viewed in this way, the Rockefeller Foundation's involvement in rice research cannot be seen ‘simply’ as an agricultural modernization project, but rather as simultaneously a sociopolitical project that extends particular modes of governance through homogenization and paternalism.     

We,Heirs of Enlightenment: Critical Theory,Democracy and Social Science

Abstract

My goal here is to come to terms with the Enlightenment as the horizon of critical social science. First, I consider in more detail the understanding of the Enlightenment in Critical Theory, particularly in its conception of the sociality of reason. Second, I develop an account of freedom in terms of human powers, along the lines of recent capability conceptions that link freedom to the development of human powers, including the power to interpret and create norms. Finally, I show the ways in which the social sciences can be moral sciences in the Enlightenment sense. This account provides us with a coherent Enlightenment standard by which to judge institutions as promoting development, understood in terms of the capabilities necessary for freedom. The relevant social science in this area might include the robust generalization that there has never been a famine in a democratic society.
