Mixed Group Validation (MGV) is an approach for estimating the diagnostic accuracy of tests. MGV is a promising alternative to the more commonly used Known Groups Validation (KGV) approach for estimating diagnostic accuracy. The advantage of MGV lies in the fact that the approach does not require a perfect external validity criterion or gold…

The Joint Committee on Standards for Educational Evaluation's Program Evaluation Standards is probably the most recognized and applied set of evaluation standards globally. The most recent edition of The Program Evaluation Standards includes five categories and 30 standards. The five categories are Utility, Feasibility, Propriety, Accuracy, and…

Prior research has considered the sequential order of function words, after the contextual words of the text have been removed, as a stylistic indicator of authorship. This research describes an effort to enhance authorship attribution accuracy based on this same information source with alternate classifiers, alternate n-gram construction methods,…

The frequency-lag hypothesis proposes that bilinguals have slowed lexical retrieval relative to monolinguals and in their nondominant language relative to their dominant language, particularly for low-frequency words. These effects arise because bilinguals divide their language use between 2 languages and use their nondominant language less…

Language-impaired individuals with autism perform poorly on tests such as non-word repetition that are sensitive clinical markers of specific language impairment (SLI). This has fuelled the theory that language impairment in autism represents a co-morbid SLI. However, the underlying cause of these deficits may be different in each disorder. In a…

If estimates are based on samples, they should be accompanied by appropriate standard errors and confidence intervals. This is true for scientific research in general, and is even more important if estimates are used to inform and evaluate policy measures such as those aimed at attaining the Europe 2020 poverty reduction target. In this article I…

One of the major challenges in teaching English to speakers of other languages is the issue of inadequate contact time between teachers and learners and between learners and comprehensible English language input. This paper emanated from a burning desire to help learners in South African educational institutions, especially those in remote areas,…

Most English-medium programs at European universities require prospective students to take standardised tests for English as a foreign language (EFL) to be admitted. However, there are contexts in which individual teachers' judgements serve the same function, thus having high-stakes consequences for the higher education entrance of their students.…

Despite many studies on assessment literacy, scant attention has been devoted to classroom assessment literacy for speaking. To bridge this gap, the present study set out to explore novice and experienced English as a foreign language (EFL) teachers' classroom assessment literacy for speaking. Twenty-six novice and experienced EFL teachers first…

We report two experiments that investigated the regulation of memory accuracy with a new regulatory mechanism: the plurality option. This mechanism is closely related to the grain-size option but involves control over the number of alternatives contained in an answer rather than the quantitative boundaries of a single answer. Participants were…

Previous research has demonstrated that preschoolers can use situation-specific (e.g., visual access) and person-specific (e.g., prior accuracy) cues to infer what others know. The present studies investigated whether 4- and 5-year-olds appreciate the differential informativeness of these types of cues. In Experiment 1 (N = 50), children used…

Typically in calibration research, subjects perform a task and make a judgment about the success of the task. Accurate findings help subjects improve self-calibration. In addition, researchers rely on the accuracy of findings to make inferences about underlying metacognitive processes. Consequently, it is important that the measures used to assess…

Real-world perspective-taking problems frequently involve interactions among individuals, suggesting a potential social element to this seemingly spatial problem. Previous studies have suggested that the agency of the target in a perspective-taking task might influence reasoning. This hypothesis is tested directly by manipulating whether one takes…

Eyewitnesses often report details of the witnessed crime incorrectly. However, there is usually more than 1 eyewitness observing a crime scene. If this is the case, one approach to reconstruct the details of a crime more accurately is aggregating across individual reports. Although aggregation likely improves accuracy, the degree of improvement…

The topic of tangible drawings for individuals who are blind is an important one to the field of visual impairment. However, it has not been addressed so far in a literature review. In this article, the authors review the selected literature on tactile picture naming and provide a quantitative look at this literature by presenting results related…
