Item response theory (IRT) is currently the dominant methodological paradigm in educational and psychological measurement. IRT models are based on assumptions about the relationship between latent traits and observed responses, so the accuracy of the methodology depends heavily on the reasonableness of these assumptions. This dissertation consists…

Social scientists have long agreed that satisficing behavior increases error and reduces the validity of survey data. There have been numerous reviews on detecting satisficing behavior, but preventing this behavior has received less attention. The current narrative review provides empirically supported guidance on preventing satisficing by…

With many children and adults affected by Attention Deficit Hyperactivity Disorder, researchers strive to understand the underpinnings of ADHD and associated factors on both a basic and applied level. The goal of this volume is to explore some of the broad array of research in the field of ADHD. The 12 chapters cover a variety of topics as varied…

Speech-related reaction time measures and fluency-related measures of 24 adult stutterers and a like number of nonstutterers were assessed to determine their diagnostic discriminative power. Findings suggested that both fluency failures and the duration of laryngeal adjustment time are useful diagnostic measures for discriminating stutterers from…

An ABAB withdrawal design was used to investigate the effects of explicit timing on accurate oral reading rate of sight word phrases of four elementary students demonstrating difficulty with reading. During baseline the students were exposed to flash cards with sight word phrases and asked to read them out loud and were not made aware that they…

Results supported the hypothesis that alcohol-related performance decrements would be observed in the vigilance and motor activity task performance of four year olds, even after adjusting for the effects of nicotine, in children whose mothers were generally not alcoholics but only social drinkers of varying amounts.

The study, with four mildly retarded primary-age students, found that constant time delay was an effective instructional strategy when students were taught to read sight words and that incidental learning also occurred as each student acquired some nontargeted spelling information. (Author/DB)

To determine whether children's knowledge of arithmetic facts becomes increasingly "automatic" with age, 7-year-olds, 11-year-olds, and adults were given a number-matching task for which mental arithmetic should have been irrelevant. Specifically, students were required to verify the presence of a probe number in a previously presented pair (e.g.,…
