By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

Objective: ADHD and autism are complex and frequently co-occurring neurodevelopmental conditions with shared etiological and pathophysiological elements. In this paper, we attempt to differentiate these conditions among the young people in terms of intrinsic patterns of brain connectivity revealed during resting state using machine learning…

In recent years, there has been increasing awareness on the benefits of social-emotional competencies (SEC) on Israeli students. A self-report SEL measure tailored to the Israeli context, however, has yet to be developed. This research aims to validate the Social-Emotional Questionnaire for Grades 4-6 (SEQ [G4-6]), a new self-report questionnaire…

Magnet schools have been a main tool or innovation in urban education settings in the United States, originating in the early 1970's and expanding into most large urban districts today (Blank, 1989). While some magnet schools do not rely on a specific criterion to determine entry, many do. This study focuses on such a setting where students must…

Compared the Wechsler Intelligence Scale for Children (Revised) (WISC-R) and the Leiter International Performance Scale with 40 average and above average students. Results indicated a curvilinear relationship between the WISC-R and the Leiter, which correlates higher at the mean and deviates as the Full Scale varies from the mean. (JAC)

Compared the Wechsler Intelligence Scale for Children (Revised) and the Woodcock-Johnson Psycho-Educational Battery (W-J) for 142 children with regular and learning-disabled (LD) class placement. The W-J and WISC-R evidenced low to moderate correlations and significant mean differences. W-J/WISC-R correlations for the regular students exceeded…

Administered the Wechsler Intelligence Scale for Children, Wechsler Intelligence Scale for Children-Revised, and Wechsler Preschool Primary Scale of Intelligence in a counterbalanced design to randomly selected elementary school children (N=72). Results indicated that the verbal Intelligence Quotients (IQs) were comparable, but the performance and…

Evaluated the validity of the Slosson Intelligence test as determined by the Wechsler Intelligence Scale for Children-Revised (WISC-R). Results indicated that the Slosson correctly predicted functioning level to within 10 IQ points of the WISC-R Full Scale scores for 88 percent of the subjects. (LLL)

Investigated the external validity of the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) in learning disabled (LD) elementary school children (N=60). Results suggested that the WJTCA's achievement emphasis jeopardizes its validity for assessing and classifying LD students within the currently accepted and mandated ability-achievement…

Examined the relationship between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and Wechsler Intelligence Scale for Children-Revised (WISC-R) in a referral sample of 52 elementary students. Results showed comparable WJTCA/WISC-R global ability estimates, contrary to lower WJTCA scores found in recent studies with learning disabled…

The Slosson Intelligence Test (revised norms) (SIT) and the WISC-R (Wechsler Intelligence Scale for Children-Revised) were compared. Results provide a moderate degree of support for the concurrent validity of the revised SIT norms, using the WISC-R as the criterion. However, the intelligence quotients on the two tests may not be interchangeable.…

Investigated the validities of IQs obtained from independent administration Terman-Merrill (T-M) versus the rescoring method (SF) of the short form of the Stanford-Binet Form L-M. Results indicated that the T-M, depending on test sequence, correlated significantly different with the Full Scale Binet IQ than did the SF rescoring method. (Author)

In order to clarify the concurrent validity of the Peabody Individual Achievement Test (PIAT) and the Metropolitan Achievement Test (MAT), product-moment correlations were computed for all subscores and total scores for 26 normal-range public school third-grade girls and boys. (Author)

Administered the Luria-Nebraska Neuropsychological Battery-Children's Revision (LNNB-Children's Revision) and The Minnesota Percepto-Diagnostic Test (MPD) to 40 learning disabled students. Low correlations were found between MPD T scores and the LNNB-Children's Revision Scales, but raw scores from the MPD had somewhat higher correlations with the…
