In her article, Icy Lee (2019, pp. 524-536) discusses the differences between comprehensive written corrective feedback (CWCF) and focused written corrective feedback (FWCF). She argues that teachers should concentrate more on focused feedback, and highlight and correct only a few grammar errors or issues with organisation, for example, instead of…

Literacy educators and researchers have long recognized the importance of increasing students' writing proficiency across age and grade levels. With the release of the Common Core State Standards (CCSS), a new and greater emphasis is being placed on writing in the K-12 curriculum. Educators, as well as the authors of the CCSS, agree that…

Tobin's work has been groundbreaking. Famously, he and his team put together a sophisticated comparative study of three ways of doing pre-school--in Japan, China, and the United States (1989). As such, this study has precedents in anthropology. What is unique in Tobin's work is that he got people from one place to comment on what they saw people…

Goo and Mackey (this issue) outline several apparent design flaws in studies that have compared the impact of different types of corrective feedback (CF). Furthermore, they argue that SLA researchers should stop comparing recasts to other types of CF because they are inherently different kinds of phenomena. Our response to their article addresses…

Executive coaching is a booming, but understudied, HRD-related practice. Given the limited number of available studies that have been deployed with rigor and systematic methods, the study by Nieminen et al. adds to our understanding of the impact of executive coaching and multisource feedback on leadership development. Explored in the context of a…

In this rejoinder, Maydeu-Olivares states that, in item response theory (IRT) measurement applications, the application of goodness-of-fit (GOF) methods informs researchers of the discrepancy between the model and the data being fitted (the room for improvement). By routinely reporting the GOF of IRT models, together with the substantive results…

Dube, Rotello, and Heit (2010) argued (a) that the so-called receiver operating characteristic is nonlinear for data on belief bias in syllogistic reasoning; (b) that their data are inconsistent with Klauer, Musch, and Naumer's (2000) model of belief bias; (c) that their data are inconsistent with any of the existing accounts of belief bias and…

[Correction Notice: An erratum for this article was reported in Vol 119(2) of Psychological Review (see record 2012-06153-001). In the article, incorrect versions of figures 3 and 6 were included. Also, Table 8 should have included the following information in the table footnote "P(A V) = probability of acquittal given unanimous verdict." All…

This article contrasts 2 approaches to analyzing transitivity of preference and other behavioral properties in choice data. The approach of Regenwetter, Dana, and Davis-Stober (2011) assumes that on each choice, a decision maker samples randomly from a mixture of preference orders to determine whether "A" is preferred to "B." In contrast, Birnbaum…

This commentary examines the role of the unit from the perspective of the definition of measurement in physics as the ratio of two magnitudes, one of which is defined as the unit; it is an important and timely contribution to measurement in the social sciences. There are many different points that could be commented upon, but the author will…

Compared to traditional test theory, where person measures are typically referenced to the distribution of a population, item response theory allows for a much more meaningful interpretation of measures as they can be directly compared to item locations. However, Stephen Humphry shows that the crucial role of the unit of measurement has been…

Humphry (this issue) deserves credit for drawing attention to the long-neglected fact that differences in item discrimination parameters are often due to empirical factors and not the product of random error components. In doing so, Humphry offers a psychometrically elegant, coherent, and practically important new model that is more flexible while…

This commentary includes a brief discussion of issues raised by the articles and systematic review contained in this special issue addressing technology applications for persons with severe developmental disabilities. Topical areas include a discussion of: (1) a need to compare "high tech" with "low tech" applications, (2) procedural fidelity, (3)…

Humphry (this issue) has written a thought-provoking piece on the interpretation of item discrimination parameters as scale units in item response theory. One of the key features of his work is the description of an item response theory (IRT) model that he calls the logistic measurement function that combines aspects of two traditions in IRT that…

Behavioral scientists have struggled with units of measurement for as long as they have struggled with measurement itself. Psychology's sole attempt at an explicit unit of measurement--the Lexile Framework for Reading (Stenner, Burdick, Sanford, & Burdick, 2006)--has been and continues to be ignored by the psychometric "cognoscenti."…
