差数显著性t检验与元分析的对比研究

利用计算机构造被试总体、模拟实验研究程序进行抽样研究,探讨显著性ｔ检验方法与元分析方法在检验实验结果数据方面的差异。在模拟实验过程中,ｔ验受到显著性水平、样本容量和总体效果大小的影响,因此最终影响了统计推断的可靠性,建议：在进行显著性检验过程中,应对统计检验能力进行估计;元分析方法以样本为元素对总体进行推断,因此具有很高的准确性和可靠性,它将很有可能成为今后心理学研究的重要统计工具。     

The Effects of Response Repetitions on Sight Word Acquisition for Students with Mild Disabilities

Single response learning trials, defined in terms of the three-term contingency model, were compared with repeated response learning trials. The purpose of Study 1 was to assess the effectiveness and efficiency of single and repeated response learning trials on sight word remediation. In Study 1, one single response learning trial having one response opportunity per word was compared to one repeated response learning trial having five response opportunities. In Study 2, three single response trials were compared to three repeated response trials. In both studies, the training conditions were compared using an alternating treatments design. Measuring the cumulative number of sight words mastered showed the training conditions equally effective. However, measuring (a) the mean duration of training sessions, (b) the cumulative frequency of words mastered per session duration, (c) the mean number of training sessions per word required for mastery, and (d) the training time per mastered word showed that the single response condition was more efficient. Discussion focuses on the need to include training data when determining best practices for teaching.     

Tableau algorithms for factor analysis by instrumental variable methods

Simple tableau algorithms are given for the noniterative instrumental variable (FABIN 2) and two stage regression (FABIN 3) factor loading estimates of Hägglund. Corresponding generalized least squares estimates of factor covariances and unique variances are introduced. An example is given for the purpose of illustration and comparison.This research was supported by NSF Grant MCS-8301587.     

The Power to Detect and Predict Individual Differences in Intra-Individual Variability Using the Mixed-Effects Location-Scale Model

Our goal is to provide empirical scientists with practical tools and advice with which to test hypotheses related to individual differences in intra-individual variability using the mixed-effects location-scale model. To that end, we evaluate Type I error rates and power to detect and predict individual differences in intra-individual variability using this model and provide empirically-based guidelines for building scale models that include random and/or systematically-varying fixed effects. We also provide two power simulation programs that allow researchers to conduct a priori empirical power analyses. Our results aligned with statistical power theory, in that, greater power was observed for designs with more individuals, more repeated occasions, greater proportions of variance available to be explained, and larger effect sizes. In addition, our results indicated that Type I error rates were acceptable in situations when individual differences in intra-individual variability were not initially detectable as well as when the scale-model individual-level predictor explained all initially detectable individual differences in intra-individual variability. We conclude our paper by providing study design and model building advice for those interested in using the mixed-effects location-scale model in practice.     

Distinguishing between authenticity and personality consistency in predicting well-being: A mixed method approach

Introduction

The relationship between role personality consistency and well-being is somewhat ambiguous, with past research relying on methods confounded by social desirability or role stereotypes, or conflating consistency with authenticity.

Writing life narratives through art practice

This article shares some of my doctoral experiences in a practice-based PhD research in arts developed at the Chelsea College of Arts, University of the Arts London. It locates art practice within the academic research realm and contributes to researchers working on autobiographical studies and practice-based research methods. By offering an overview on my research topic focusing on the relationship between language and place in the life of Brazilian women living in London, I reflect on the relevance of “not-knowing” as a fruitful space for researching autobiographical and situated life narratives through art practice. The article concludes that qualitative methods are relevant for building passages from the individual to the collective sphere of an art practice developed within geographical displacement and in the context of academic research.     

Video installation as a creative means of representing temporality in visual data

This paper describes the use of video installation as a creative means of engaging audiences in visual research. A detailed image-based overview of the project, 1247 Days on Whymark Avenue, is also presented. This interactive video installation offered viewers a level of phenomenological immersion in the compressed temporality and asynchronous dialogue captured by this visual research project. This film is part of a larger research project on the longitudinal photo-documentation of urban life (Hansen & Flynn 2015a). The project uses repeat photography to study street art and graffiti as visual dialogue.     

Women speaking through embroidery: using visual methods and poetry to narrate lived experiences

This article aims to highlight the ways in which visual methods can be used to narrate lived experiences. Additionally, I also draw from self-written poetry as a way to speak to the embroideries and using poems as a form of alternative analysis that assist in interpreting the embroideries. I embarked on a research project where I used embroidery as a visual methodological tool wherein participants could narrate their stories visually, as a way to shift from solely relying on text and the spoken language. The aim was to highlight various ways in which stories could be told and, commensurately, an acknowledgment of multiple forms of knowledge production is made manifest. The findings and various interpretations of the embroideries have been published elsewhere (see Segalo 2011, 2014, 2016; Segalo, Manoff & Fine 2015). On the basis of the foregoing, I argue that platforms need to be created wherein the academic space and ways in which information and knowledge are presented become open to multiple forms of representation.
