Definitions of specific language impairment (SLI), for both research and clinical purposes, often state that nonverbal IQ scores must be within normal limits. This use of nonverbal IQ has been criticized on several grounds, including lack of equivalence between tests. In the current study, a sample of 204 adolescents with and without language…

This exploratory study investigated sensory-motor mechanisms in five people who stutter (PWS) and five people who do not (PNS). Lip kinematic and coordination data were recorded as they produced bi-syllabic nonwords at two rates (normal and fast) in three conditions (jaw-free, immediately after insertion of a bite-block, and after a 10-min…

Objective: Functional MRI was used to determine differences in patterns of cortical activation between children who suffered perinatal left middle cerebral artery (MCA) stroke and healthy children performing a silent verb generation task. Methods: Ten children with prior perinatal left MCA stroke (age 6-16 years) and ten healthy age matched…

In a 10-day training, the efficacy of spelling pronunciations on German speaking 5th-graders' spelling skills for irregular words was examined. Poor spellers were less efficient in learning the spelling pronunciations than age-adequate spellers. On post-tests, 1 week after the last training day and between 5 and 12 weeks after post-test 1, poor…

The current study extends the development and evaluation of an existing and previously evaluated sexual assault risk reduction program with a self-defense component for college women (N = 300). The program protocol was revised to address psychological barriers to responding assertively to risky dating situations, and a placebo-control group was…

Objective: This research evaluates effects of vestibular stimulation by Comprehensive Motion Apparatus (CMA) in ADHD. Method: Children ages 6 to 12 (48 boys, 5 girls) with ADHD were randomized to thrice-weekly 30-min treatments for 12 weeks with CMA, stimulating otoliths and semicircular canals, or a single-blind control of equal duration and…

When causal inferences are to be synthesized across multiple studies, efforts to establish the magnitude of a causal effect should be balanced by an effort to evaluate the generalizability of the effect. The evaluation of generalizability depends on two factors that are given little attention in current syntheses: construct validity and external…

Deep orthographies usually represent morphology and phonology simultaneously; both resources are necessary for spelling. In shallow orthographies, such as Spanish, phonology would be enough to spell most words. However, morphological knowledge may also take part in spelling. This study examined how Spanish children in 1st (N = 148), 2nd (N = 155)…

The present study examines classroom learners' course of grammatical development in acquiring the interpretive correlates of variable adjective position in French. Eventual attainment of the target language system requires not only knowledge of linear word-order possibilities within the determiner phrase that differ from their native language…

This study provides the first empirical investigation of Fatal Vision Goggles as a prevention tool aimed at changing attitudes toward drinking and driving. College students (N = 163) were randomly assigned to three groups: A control group, a group wearing the goggles, and a group of onlookers who were observing those wearing the goggles. Attitudes…

The goal of this study was to empirically distinguish a range of mentor relationships and to evaluate their differential influence on adolescent outcomes. The study makes use of data that were collected as part of a national evaluation of Big Brothers/Big Sisters of America. The evaluation included 1138 youth, ranging in age from 10 through 16 (M…

Two groups of undergraduates received simulated amnesia instructions that either informed them how amnesics perform on memory tasks (informed; n = 11) or did not inform them about how amnesics perform on memory tasks (uninformed; n = 9). A third group received no such instructions (control; n = 9). Performance on a negative priming task revealed…

The present study attempted to investigate the effect of using blog-based peer feedback on the persuasive writing of EFL business management students at the community college in Bisha, King Khalid University, Saudi Arabia. The study used a pre-test/post-test experimental and control group design. An experimental group and a control group were…

The purpose of this study is to determine whether a pedagogy grounded in dialogical ideals has the potential to empower students to make changes in English classroom interaction. The study first scrutinized the traditional "banking" educational system in English classrooms in which students were passive learners to realize students'…

One of the most powerful educational option in open and distance education is web-based learning. A blended (hybrid) course combines traditional face to face and web-based learning approaches in an educational environment that is nonspecific as to time and place. The study reported here investigated the impact of web based resource material…
