Objective: Bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD) are often comorbid or confounded; therefore, we evaluated emotional face identification to better understand brain/behavior interactions in children and adolescents with either primary BD, primary ADHD, or typically developing controls (TDC). Method: Participants…

The purpose of this study was to examine the effects of multilevel support on first-grade teachers' accurate use of research-based strategies during beginning reading instruction and the extent to which teachers maintained use of these strategies. Teachers were trained to use research-based strategies, including choral responding, response…

As some colleges and universities experience low rates of student success, many point to the large number of students who are placed into and fail to complete developmental education courses. Research examining the efficacy of course placement tests has suggested that success rates would increase if students were placed more accurately. A recent…

Accurate teacher judgments of student characteristics are considered to be important prerequisites for adaptive instruction. A theoretically important condition for putting these judgments into operation is judgment confidence. Using a German sample of 96 teachers and 1,388 students, the authors examined how confident teachers are in their…

This dissertation reports the results of three studies and a pilot study. The first study was a Monte Carlo validation study that examined the accuracy of a new visual inspection method, the semi-interquartile range method. Results of the study indicated that this method had lower levels of power than a previously validated method, the…

We assessed the extent to which failures in sustained attention were associated with chronic mild traumatic brain injury (mTBI) deficits in cognitive control among college-age young adults with and without a history of sport-related concussion. Participants completed the ImPACT computer-based assessment and a modified flanker task. Results…

In the current study we investigated word, pseudoword and story reading in Dutch speaking braille and print readers. To examine developmental patterns, these reading skills were assessed in both children and adults. The results reveal that braille readers read less accurately and fast than print readers. While item length has no impact on word…

Individuals with autism spectrum disorders (ASD) report difficulty integrating simultaneously presented visual and auditory stimuli (Iarocci & McDonald, 2006), albeit showing enhanced perceptual processing of unisensory stimuli, as well as an enhanced role of perception in higher-order cognitive tasks (Enhanced Perceptual Functioning (EPF) model;…

The present study examined the impact of divided attention on children's and adults' neutral and negative true and false memories in a standard Deese/Roediger-McDermott paradigm. Children (7- and 11-year-olds; n = 126) and adults (n = 52) received 5 neutral and 5 negative Deese/Roediger-McDermott word lists; half of each group also received a…

Introduction: This article reports on a study that explored the benefits and drawbacks of using spatially positioned synthesized speech in auditory interfaces for computer users who are visually impaired (that is, are blind or have low vision). The study was a practical application of such systems--an enhanced word processing application compared…

The authors investigated whether some advantages of tutoring over other instructional methods are due to microadaptation, or, tutors basing their actions on assessments of tutees they develop during tutoring. In a 2 × 2 between-subjects experiment, independent variables were shared experience (tutors either worked with the same or a different…

In wireless sensor networks, more so generally than in other types of distributed systems, clock synchronization is crucial since by having this service available, several applications such as media access protocols, object tracking, or data fusion, would improve their performance. In this dissertation, we propose a set of algorithms to achieve…

The purpose of this study was to determine the efficacy of specific, individualized training for students with different levels of mathematical difficulties. Fifty-four students, with either severe or mild math difficulties, were assigned to individualized training or to a control condition. Ten students with severe math difficulties…

Proficiency in English language and how it is measured have become central issues in higher education research as the English language is increasingly used as a medium of instruction and a criterion for admission to education. This study evaluated the English language assessment in the foundation Programme at the Colleges of Applied sciences in…

The Effects of the Language for Learning curriculum (Engelmann & Osborne, 1999) on through-the-air (i.e., signed and/or spoken) English skills for students who are deaf or hard of hearing (DHH) were examined by means of a single-subject, concurrent-multiple-probes-across-participants design. Four 11-year-old participants varied in auditory…
