Embedded performance validity tests (PVTs), like Digit Span PVTs from Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), offer a valuable means of evaluating validity without extending administration time. This study investigated the utility of novel indices of performance inconsistency for WAIS-IV Digit Span (DS IRs) in the detection of…

The authors demonstrate the increment of clinical validity in early childhood assessment of physical impairment (PI), developmental delay (DD), and autism (AUT) using multiple standardized developmental screening measures such as performance measures and parent and teacher rating scales. Hierarchical regression and sensitivity/specificity analyses…

The consensus of most intelligence scholars is that the Flynn effect (FE) is real, IQ test batteries are now routinely restandardized on a regular basis. A cornerstone in Flynn's explanation of the FE is his analysis of select Wechsler subtest scores across time. The featured articles by Kaufman and Zhou, Zhu, and Weiss question whether Flynn's…

Inclusion of students with disabilities in district-wide and state assessments is mandated by federal regulations, and teachers sometimes play an important role in rating these students' work. In this study, trained teachers rated student proficiency in performance assessments in language arts and mathematics in third, fifth, and ninth grades. The…

The Woodcock Johnson III Brief Assessment is a "maximum performance test" (Reynolds, Livingston, Willson, 2006) that is designed to assess the upper levels of knowledge and skills of the test taker using both power and speed to obtain a large amount of information in a short period of time. The Brief Assessment also provides an adequate…

The ecological validity of the Conners' Continuous Performance Test II (CPT-II) was examined using a sample of 206 first- and second-grade children. Children's CPT-II scores were correlated with observations of inattentive/hyperactive behavior during CPT-II administration, observations of children's behavior during analogue academic task,…

Elementary school children in three grade groups (Grades K/1, 3, and 5/6) completed either the auditory or the visual 1/9 vigilance task from the Gordon Diagnostic System (GDS) as well as subtests from the Wechsler Intelligence Scale for Children--Third Edition and auditory or visual processing subtests from the Woodcock-Johnson Tests of Cognitive…
