Adolescents who break the law have experienced situations that increase the likelihood of becoming involved in criminal activities such as drug use, gang involvement, adverse economic conditions, among others. All this, added to their stage of human development, which is characterized by physical, cognitive, social and emotional changes, can lead…

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…

This investigation provides internal consistency reliabilities for the Wechsler Memory Scale--Fourth Edition (WMS-IV) subtest and index discrepancy scores using the standardization samples of the Adult and Older Adult batteries. Subtest reliabilities ranged from 0.00 to 0.93 for Adults and 0.25 to 0.94 for Older Adults. Three of 91 Adult…

Background: Executive functions (EF) impairments have long been observed in children and youths with autism spectrum disorders (ASD). Until very recently, little attention has been paid to examine EF profiles of adults with ASD. Given the importance of EF to cope with the demands of daily life and participate in society (e.g. maintaining an…

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.…

Research on high-ability postsecondary students has increased in recent years; yet identifying such students can be challenging. The International Cognitive Ability Resource (ICAR) is an online, open-access tool designed to facilitate measurement of cognitive abilities in research. We evaluated whether the ICAR is appropriate to identify…

Labels for scores stemming from intelligence tests have been employed since their inception in the United States. The purpose of this study was to systematically identify and document score labels for IQs used during the past 102 years. Using pairs of reviewers, score labels from 40 tests were reviewed, and 61 unique labels were identified.…

Critical thinking, intelligence, and language aptitude are three cognitive factors, each, in its own way, influencing our lives. They are important in successful reasoning, problem-solving, and foreign language learning, and thus are worth studying regarding their influence on individuals' language-related skills, in particular, foreign…

The hippocampus has long been recognized as important for the formation of long-term memory. Recent work has suggested that the hippocampus might also be important for certain kinds of spatial operations, as in constructing scenes, shifting perspective, or perceiving the geometry of scenes and their boundaries. We explored this proposal using a…

Most study samples show less variability in key variables than do their source populations due most often to indirect selection into study participation associated with a wide range of personal and circumstantial characteristics. Formulas exist to correct the distortions of population-level correlations created. Formula accuracy has been tested…

The conceptualization of giftedness continues to be a widely debated topic within the field. Recently, there has been a shift from a psychometric view of giftedness to inclusion of conative and contextual factors. How one defines and conceptualizes "gifted" drives assessment and identification practices. Conceptualization also guides the…

The purpose of this study is to investigate the reasons why Greek young adults with Specific Learning Disabilities (SLD) seek learning assessments. The study sample consisted of 106 adults meeting Diagnostic and Statistical Manual of Mental Disorders criteria for SLD. Data were collected through self-report records (clinical interview) of adults…

The Cattell-Horn-Carroll (CHC) model is a comprehensive model of the major dimensions of individual differences that underlie performance on cognitive tests. Studies evaluating the generality of the CHC model across test batteries, age, gender, and culture were reviewed and found to be overwhelmingly supportive. However, less research is available…

The effects of extended time on the writing performance of university students with learning disabilities (LD) was examined. Thirty-eight students (19 LD; 19 non-LD) completed a collection of cognitive, linguistic, and literacy measures, and wrote essays under regular and extended time conditions. Limited evidence was found to support the…

This article provides guidelines for an entry-level course that prepares psychology students and practitioners to acquire entry-level skills, abilities, knowledge, and attitudes important to the individual assessment of intellectual abilities of children and youth.
