In his focus article, "Rethinking Traditional Methods of Survey Validation," published in this issue of "Measurement: Interdisciplinary Research and Perspectives," Andrew Maul wrote that it is commonly believed that self-report, survey-based instruments can be used to measure a wide range of psychological attributes, such as…

A debate is emerging concerning the use of deception in social science research (especially when it employs experimental methods), driven primarily by the relatively recent move by many economists into experimental work. These economists generally argue that deception should be banned. Deception includes a variety of practices in social science…

Griffiths, Christian, and Kalish (this issue) present an iterative-learning paradigm applying a Bayesian model to understand inductive biases in categorization. The authors argue that the paradigm is useful as an exploratory tool to understand inductive biases in situations where little is known about the task. It is argued that a theory developed…

Six unsuccessful attempts at replicating a key finding in the linguistic relativity literature [Boroditsky, L. (2001). Does language shape thought?: Mandarin and English speakers' conceptions of time. "Cognitive Psychology," 43, 1-22] are reported. In addition to these empirical issues in replicating the original finding, theoretical issues…

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…

The authors respond to the article by H. F. Coelho, P. H. Canter, and E. Ernst (2007), which reviewed the current status of mindfulness-based cognitive therapy (MBCT). First, they clarify the randomization procedures in the 2 main MBCT trials. Second, they report posttreatment and follow-up data to show that trial participants allocated to…

N. Stewart, G. D. A. Brown, and N. Chater presented a relative judgment model (RJM) of absolute identification, in which the current stimulus is judged relative to the preceding stimulus. S. Brown, A. A. J. Marley, and Y. Lacouture found that the RJM does not predict their finding of increased accuracy after large stimulus jumps, except at the…

In the last two decades, La Heij and colleagues have presented accounts of a number of context effects in Stroop-like word-production tasks. Roelofs (2007 this issue) criticises various aspects of our proposals, ranging from the number of processing stages assumed to details of simulation results. In this reply we first argue that we do not…

Contends that theoretical and conceptual problems relating to the validation of assessment centers must be resolved before quantitative validation methods may be used. An open design is suggested to facilitate conceptual clarification. (CH)

Method: My comments reflect a focus on the client values piece of…

Purpose: This paper is a personal reaction to Gillam and Gillam's treatise on evidence-based decision making in schools. This evaluation focuses principally on the costs and benefits of clinicians' search for external evidence, potential problems associated with efforts to grade that evidence, and the integration of this evidence with "internal"…
