Over the past decade educational research has been stimulated by new legislation such as the No Child Left Behind Act. Increasing emphasis is being placed on accurately quantifying the success of treatment programs through student achievement scores, so precise estimation is vital for establishing the efficacy of new methodology. Ranked set…

Text analysis has become an important research activity in the Department of Veterans Affairs (VA). Statistical text mining and natural language processing have been shown to be very effective for extracting useful information from medical documents. However, neither of these techniques is effective at extracting the information stored in…

The purpose of this study was to determine which of the three reading fluency subskills were most strongly correlated with reading comprehension in adolescent at-risk readers. The participants were 82 adolescent males (ages 13-19) who had been committed to a juvenile detention facility. Archival data from a two-year period was collected from a…

Although models of visual search have often assumed that attention can only be set for a single feature or property at a time, recent studies have suggested that it may be possible to maintain more than one attentional control setting. The aim of the present study was to investigate whether spatial attention could be guided by multiple attentional…

Background: There is evidence to suggest that people with aphasia (PWA) may have deficits in attention stemming from the inefficient allocation of resources. The inaccurate perception of task demand, or sense of effort, may underlie the misallocation of the available attention resources. Given the lack of treatment options for improving attention…

The focus of this paper is assessing the impact of measurement errors on the prediction error of an observed-score regression. Measures are presented and described for decomposing the linear regression's prediction error variance into parts attributable to the true score variance and the error variances of the dependent variable and the predictor…

In visual search, a set of distractor items can be suppressed from future selection if they are presented (previewed) before a second set of search items arrive. This "visual marking" mechanism provides a top-down way of prioritizing the selection of new stimuli, at the expense of old stimuli already in the field (Watson & Humphreys,…

According to the age-of-acquisition hypothesis, words acquired early in life are processed faster and more accurately than words acquired later. Connectionist models have begun to explore the influence of the age/order of acquisition of items (and also their frequency of encounter). This study attempts to reconcile two different methodological and…

Four experiments examined haptic perception of two distal spatial properties in a bypass event. A hook suspended a string held taut between the participant's finger and a weight. Moving their fingers laterally beneath the hook, participants estimated the finger's point of closest approach (PCA) to the hook and bypass distance (BPD; i.e., hook…

The present study examined possible memory and metacomprehension benefits of using a combined question self-generation and answering technique, relative to rereading, as a study strategy for expository passages. In the 2 question self-generation and answering conditions (detail or conceptual questions), participants were prompted on how to…

This study examined the effects of inaccurate rules on generation of rumor among participants and their productivity in an organizational analog setting. Dyads of participants were given an explicit rule that described a contingency (i.e., number of points earned for correct responses). Experiments 1 and 2 utilized quasirandom and counterbalanced…

Tucker and chained linear equatings were evaluated in two testing scenarios. In Scenario 1, referred to as rater comparability scoring and equating, the anchor-to-total correlation is often very high for the new form but moderate for the reference form. This may adversely affect the results of Tucker equating, especially if the new and reference…

Presenting inconsistent postevent information about a witnessed incident typically decreases the accuracy of memory reports concerning that event (the "misinformation effect"). Surprisingly, the "reversibility" of the effect (after an initial occurrence) has remained largely unexplored. Based on a "memory conversion" theoretical framework and…

The accuracy of simple actions is swiftly determined through specific monitoring brain systems. However, it remains unclear whether this evaluation is accompanied by a rapid and compatible emotional appraisal of the action that allows to mark incorrect actions as negative/bad and conversely correct actions as positive/good. In this study, we used…

Reliabilities of the two most widely used intraindividual variability indicators, "ISD[superscript 2]" and "ISD", are derived analytically. Both are functions of the sizes of the first and second moments of true intraindividual variability, the size of the measurement error variance, and the number of assessments within a burst. For comparison,…
