This study proposes a Bayesian method for diagnostic classification models (DCMs) for a partially known Q-matrix setting between exploratory and confirmatory DCMs. This Q-matrix setting is practical and useful because test experts have pre-knowledge of the Q-matrix but cannot readily specify it completely. The proposed method employs priors for…

Purpose: The purpose of this study was to examine the nature of speech disfluencies in autistic young adults and controls by using a wide-range disfluency classification of typical disfluencies (TD; i.e., filled pauses, revisions, abandoned utterances, and multisyllable word and phrase repetitions), stuttering-like disfluencies (SLD; i.e., sound…

This study investigated the utility of four WAIS-IV Digit Span (DS) indices (traditional Reliable Digit Span [RDS], RDS-Working Memory [RDS-WM], RDS-Revised [RDS-R], and DS Age-Corrected Scaled Score [ACSS]) as embedded performance validity tests (PVTs) among a sample of 342 consecutive adults referred for neuropsychological evaluation of ADHD.…

Sensory sensitivity is common in autistic people and since the "Diagnostic and Statistical Manual of Mental Disorders" (5th ed.), hypo- and hyper-responsiveness to sensory stimuli are part of one of the criteria domains for an autism spectrum disorder classification. For scientific research and the clinical practice, one needs reliable…

Recent research suggests that most 4-year college students diagnosed with specific learning disability (SLD) do not meet objective criteria for the disorder, show normative deficits in academic skills, or have childhood histories of SLD. The purpose of this study was to examine the functioning of students diagnosed with SLD attending community…

The Vygotsky Blocks Test assesses problem-solving styles within a theoretical framework for the development of higher mental processes devised by Vygotsky. Because both the theory and the associated test situate cognitive development within the child's social and linguistic context, they address conceptual issues around the developmental relation…

Although increased age is associated with greater errors in spatial memory tasks, it is unclear if there are age differences in error types. To investigate this, 334 participants (ages 22-88) completed a task in which they remembered object locations across multiple study-test trials. Far and close error types were categorized based on the spatial…

The purpose of this article was to describe an initial step developing a new scale to identify individuals with learning disabilities (LD) and test anxiety. Eighty-eight students answered the "Minnesota Multiphasic Personality Inventory-2" (MMPI-2). The participants were drawn from the following three groups: (a) adults with LD and test…

Analysis of correlations between Verbal and Full Scale IQ scores for 231 high-IQ psychiatric outpatients indicated that Verbal IQ appears partially valid as a WAIS short form for this higher IQ group. Results are interpreted in terms of Resnick and Entin's short form validity criteria. (Editor/SJL)

Sixteen-year-old EMR children were administered the WAIS and WISC-R in counterbalanced order to determine the comparability of the two assessment instruments. The WAIS was found to yield significantly higher scores. Results suggest differences between the two instruments among children of subnormal intelligence. (Author)

A study examined the identification of distinct subgroups of learning-disabled young adults based on their ability to generate written language. Two subgroups of learning-disabled college students, the language strong/visually weak (N=22) and the visually strong/language weak (N=10), were identified based on evaluation of 32 essays. Subjects were…
