Network models of the WAIS-IV based on regularized partial correlation matrices have been reported to outperform latent variable models based on uncorrected correlation matrices. The present study sought to compare network and latent variable models using both partial and uncorrected correlation matrices with both types of models. The results show…

The Woodcock-Johnson IV Tests of Cognitive Abilities (WJ IV COG) is a comprehensive assessment battery designed to assess broad and narrow cognitive abilities, as defined by the Cattell-Horn-Carroll (CHC) theory of intelligence. Previous studies examined the invariance of the WJ assessments across sex and age groups using factor analytic methods.…

Accumulating evidence indicates that co-occurring alexithymia underlies several facets of the social-emotional difficulties common in individuals with autism spectrum disorder. The mechanisms involved, however, remain poorly understood because measuring alexithymia relies heavily on self-report. To address this issue, carefully matched groups of…

Researchers of the gifted have traditionally advanced the theory, though they are often without data to support it, that an association between intellectual and/or creative giftedness and mood disorders exists. This assumed association is often referred to as the "mad genius theory." This article explores the origins and development of…

New editions of the Wechsler Adult Intelligence and Memory scales are now available. Yet, given the significant changes in these new releases and the skepticism that has met them, independent evidence on their psychometric properties is much needed but currently lacking. We administered the WAIS-IV and the Older Adult version of the WMS-IV to 145…

A psychometric evaluation on the measurement of self-report anxiety and depression using the Beck Depression Inventory (BDI-II), State Trait Anxiety Inventory, Form-Y (STAI-Y), and the Personality Assessment Inventory (PAI) was performed using a sample of 534 generally young adults seeking psychoeducational evaluation at a university-based clinic.…

Schools often administer brief intelligence tests as the first step in the identification of students who are cognitively gifted. However, brief measures are often used without consideration of underlying constructs or the psychometric properties of the measures and without regard to the links between screening decisions and educational…

Ruchalla, Schalt, and Vogel (1985) reported a negative correlation between the g-loadness of intelligence subtests and the extent to which the subtests correlated with reaction times. Possible methodological problems with Ruchalla et al. are described, and results of two other studies pertinent to the issue are discussed. (Author/LMO)

This research studied the interchangeability of individually administered and group administered cognitive tests. Seventy undergraduate students took the Hebrew version of the WAIS-R (Wechsler Adult Intelligence Scale-Revised), and their IQs were measured. They also took the IPET (Israeli Psychometric Entrance Test) and their IPET scores were…

According to Gough and Tunmer (1986), in a "Simple View of Reading" (SVR), Reading comprehension (RC) = Decoding (D) x Linguistic Comprehension (C). To further evaluate this model, this paper describes an exploratory study of the performance of 60 university students, the majority of whom received academic accommodations at university to…
