The dominant methodological approach in psychological research has involved the use of quantitative methods within a positivist framework. In this article we argue that both qualitative and quantitative methods have their strengths and limitations, depending on the research question under investigation. We examine some of the advantages of qualitative methods, paying particular attention to the value of such methods for feminist researchers. We challenge the positivist assumption that all research should be apolitical and value-free, arguing that the political context in which all research studies take place plays an important role in decisions about the appropriate research methods to use. Despite the value attached to qualitative methods by feminist researchers, there may be projects for which quantitative methods, or a combination of qualitative and quantitative techniques, are more suitable. We draw on examples from our research on the transition from school to the job market for young people, and a study of 16- to 19-year-old first time mothers to illustrate these points, examining the practical implications of our arguments for applied social psychology research. 相似文献

The MRG was published 1988 in order to support developments in group psychotherapy methods as one of the all too few process observation research methods for studying group-as-a-whole. After 9 years of what pilot studies have labeled successful clinical trials, this study aims at validating the MRG against the established SAVI: Structural Analysis of Verbal Interaction (Agazarian & Simon 1989). Videotaped group sessions from short-term groups for alcohol dependent patients conducted along two therapy methods, one behaviorally oriented and the other group analytic, are used as material. The MRG is validated in the study, confirmed to be clinically valuable, and some interesting comparisons between the two treatment modalities are also made. 相似文献

In the last several years, various organizations have produced strikingly similar documents by which institutions for retarded persons are judged for licensure. The purpose of the present study was to determine whether residential units that were licensed differed from residential units that were not licensed in terms of the active programming behaviors of their staff and residents. Data were collected through a time-sampling procedure that yielded about 160,000 observations on eight staff and six resident behaviors. Results showed that the licensed units were just as derelict as unlicensed units in providing habilitative programming for their retarded residents. Maladaptive responding by residents occurred at least as much as task-related behaviors: residents spent as much time self-stimulating as they did in programming; they also engaged in self-abusive behavior about as much time as they engaged in on-task responding. Results were discussed in terms of the failure of governmental regulations that are not based on observation to adequately assess habilitative programming. 相似文献

Time-series analysis in operant research 总被引:1,自引:0,他引:1
A time-series method is presented, nontechnically, for analysis of data generated in individual-subject operant studies, and is recommended as a supplement to visual analysis of behavior change in reversal or multiple-baseline experiments. The method can be used to identify three kinds of statistically significant behavior change: (a) changes in score levels from one experimental phase to another, (b) reliable upward or downward trends in scores, and (c) changes in trends between phases. The detection of, and reliance on, serial dependency (autocorrelation among temporally adjacent scores) in individual-subject behavioral scores is emphasized. Examples of published data from the operant literature are used to illustrate the time-series method. 相似文献

研究视觉分别搜索在左右视野靶时,脑两侧前额叶视觉加工的机制。14名有偿被试参加实验。实验任务是从正圆中所存在的垂直方向的箭头,搜索出水平方向箭头,并判断箭头方向。靶所在左右视野经过镜面处理完全对应。结果发现当靶出现约220ms后左右两侧脑区ERP出现分叉点,靶对侧与靶同侧的前脑区相比有非常显著的负向电位活动,对侧和同侧的N2延续40-80ms。分析认为靶对侧前额脑区N2负向活动增强是注意的等级提高,聚焦点收窄,使所要加工的靶在主效应脑区(靶视野对侧脑区)“跃显”出来,在得到正反馈诱导的同时,也得到更多的资源,靶同侧脑区N2可能与中断或阻止其他无关信息的涌入有关。 相似文献

In contrast to Jean-Francois Lyotard’s classic warning, postmodern society in the United States seems increasingly influenced by metanarratives—religious metanarratives. This article examines the implications of this religious resurgence for educational researchers. It offers a competing analysis of the postmodern that draws on Harold Bloom, Slavoj ŽiŽek and others to identify the gnostic elements in contemporary religiosity, both in Europe and the United States. This competing reading of postmodern religiosity suggests a reframing of Lyotard’s paralogy—research that searches for instabilities in the framework of knowledge. Drawing examples from recent educational research, I will argue for ways in which researchers can better engage religion in their work.The author would like to thank the anonymous reviewer who brought to his attention additional texts and debates about this highly interdisciplinary topic. 相似文献

Herkert JR 《Science and engineering ethics》2001,7(3):403-414
Three frames of reference for engineering ethics are discussed—individual, professional and social—which can be further broken
down into “microethics” concerned with individuals and the internal relations of the engineering profession and “macroethics”
referring to the collective social responsibility of the engineering profession and to societal decisions about technology.
Few attempts have been made at integrating microethical and macroethical approaches to engineering ethics. The approach suggested
here is to focus on the role of professional engineering societies in linking individual and professional ethics and in linking
professional and social ethics. A research program is outlined using ethics support as an example of the former, and the issuance
of position statements on product liability as an example of the latter.
An earlier version of this paper was presented at the International Symposium on Technology and Society 2000 (ISTAS 2000),
Rome, Italy, 7 September 2000.
