The author's objective for this reply in reexamining opportunity cost was to draw attention to two conflicting definitions of the concept in current use and to argue the case for dropping one of them. The comments of Daniel Arce, Rod O'Donnell, and Daniel Stone might be read as demonstration that the author has failed on both counts. Such a…

Zimmerman (2014) suggested that our reanalysis adds little to the scientific literature. We disagree. We clarify our motivations and explain how further analyses based on his suggestion for age do not change our conclusions. Moreover, we believe the nascent experimental literature is more in line with our interpretations than Zimmerman's. We…

A response is made to a paper that urges the use of the Rasch model for educational assessment. This paper argues that the model is inadequate and that claims for its efficacy are exaggerated and technically weak.

In this technical comment, we argue that Morgan et al.'s claim that there is no minority overrepresentation in special education is in error due to (a) sampling considerations, (b) inadequate support from previous and current analyses, and (c) their failure to consider the complexities of special education disproportionality. [For Morgan et al.'s…

Cooper et al. (this issue) develop an interactive activation model of spatial and imitative compatibilities that simulates the key results from Catmur and Heyes (2011) and thus conclude that both compatibilities are mediated by the same processes since their single model can predict all the results. Although the model is impressive, the…

Twitter offers an engaging way to introduce students to reader-oriented interpretation of the Bible. The exercise described here introduces students to the idea that the reader has a role in the production of a text's meaning, which thus varies from reader to reader. Twitter enables us to capture the real-time thoughts of a variety of…

In this "Idea Sharing" article, the author introduces Shakespeare's "Measure for Measure" as a critique of King James I's (England) concept of an absolute monarchy, in his constitutional treatise, "Basilikon Doron (1599)," the "kingly gift" that advises the young prince on the ethics of government and how to…

For the last decade Michelle Kamhi has been prominent in her critique of contemporary art education. In her philosophy she positions herself as an essentialist who believes there are essential masterworks that define fine art, and the curriculum in art should teach fine art only. Her definition of fine art focuses on representation in painting and…

Smith, Vogel, Madon, and Edwards' (2011) recent article tested dyadic power theory (DPT) by examining the use of touch as a compliance-gaining tactic in the conflicts of married couples. In this response, we raise a methodological issue about the touch behaviors examined by Smith et al. and also pose a theoretical critique that their test of DPT…

This commentary is in response to Tim Keller's article "The National Implications of 'Cain v. Horne.'" In his analysis, Keller asserts that the Arizona Supreme Court wrongfully struck down a voucher program for students with special needs by characterizing the voucher as aid to schools rather than aid to students. In this response to…

J. T. Wixted argued that nearly every recent study that was designed to differentially test the unequal-variance signal-detection (UVSD) and dual-process signal-detection (DPSD) models has yielded findings that strongly support the UVSD model. C. M. Parks and A. P. Yonelinas did not address these studies in detail and instead focused mainly on…

N. Stewart, G. D. A. Brown, and N. Chater's relative judgment model includes three core assumptions that enable it to predict accurately the vast majority of "classical" phenomena in absolute identification choices, but not the time taken to make them, including sequential effects, such as assimilation and contrast. These core assumptions, coupled…

M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (see record 2002-06215-001) argued that humans compute nonadjacent statistical relations among syllables in a continuous artificial speech stream to extract words, but they use other computations to determine the structural properties of words. Instead, when participants are familiarized with a…

Paul Stapleton's (2006) critique of quantitative research brings to the surface some common interpretive problems arising when experimental and quasi-experimental research designs are compared. While Stapleton may be correct in pointing out the superiority of experimental research designs because they best eliminate the influence of extraneous…

There has been considerable debate on the nature of scholarship over the past two decades. A key contribution to this debate is a seminal work in which Boyer (1990) articulates an expanded notion of scholarship. One of the four functions of scholarship that Boyer identifies in this expanded view of scholarship is the scholarship of integration. In…
