Lenhard and Lenhard (2021) investigate how regression-based continuous norming can enhance the quality of norm scores in psychometric testing. Their study compares semiparametric continuous norming (SPCN) with conventional methods, evaluating performance across a wide range of simulated test conditions and sample sizes. Background Norm scores are crucial in psychological and …
The article by Coelho, Hanel, and Wolf (2018) presents the NCS-6, a shortened version of the Need for Cognition Scale (NCS-18). This scale measures an individual’s tendency to engage in and enjoy thinking, a concept that has become significant in fields like social and medical sciences. By reducing the original …
The article “Convergent, Discriminant, and Concurrent Validity of Nonmemory-Based Performance Validity Tests” by Webber, Critchfield, and Soble (2020) analyzes the effectiveness of nonmemory-based Performance Validity Tests (PVTs) in detecting noncredible performance during neuropsychological assessments. The study evaluates tools like the Dot Counting Test (DCT) and variations of the WAIS-IV Digit …
Short-form (SF) IQ estimations are often used in clinical settings to provide efficient assessments of intelligence without administering the full test. Lace et al. (2022) examined the effectiveness of various five- and four-subtest combinations for estimating full-scale IQ (FSIQ) on the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V). Their findings …
The Wechsler Adult Intelligence Scale—Fourth Edition (WAIS-IV) is widely recognized as one of the most utilized intelligence tests for adults. While previous studies have examined the test’s structure using the Cattell–Horn–Carroll (CHC) model, individuals aged 70 and older have often been excluded due to the absence of supplemental subtests in …
Research comparing IQ scores from the Stanford-Binet and the Wechsler Adult Intelligence Scale (WAIS) reveals significant differences. These findings hold implications for assessing intellectual disabilities, diagnosing cognitive impairments, and understanding the practical outcomes of these assessments. This analysis reflects on the study conducted by Silverman et al. (2010), which reported …
This article examines the structure and cross-age consistency of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). The research evaluates how the test aligns with the Cattell-Horn-Carroll (CHC) theory of intelligence and whether it measures the same constructs across different age groups. The findings offer valuable insights into the application and …
Abstract This study aimed to examine the relationships between the Jouve Cerebrals Crystallized Educational Scale (JCCES) Crystallized Educational Index (CEI) and various measures of cognitive abilities and academic achievement. Pearson correlation analyses were used to test the research hypotheses. The results showed strong correlations between the JCCES CEI and measures …
Abstract This research focused on assessing the reliability of the Jouve Cerebrals Test of Induction (JCTI), a computerized 52-item test measuring nonverbal reasoning without time constraints. The reliability of the test was determined through Cronbach’s Alpha coefficients and standard errors of measurement (SEm), calculated across various age groups. A total …
Abstract This study aimed to revise the Epreuve de Performance Cognitive (EPC), a nonverbal, sequential reasoning test, by incorporating a stopping requirement after five consecutive misses, and to evaluate the psychometric properties of the revised EPC. Data from 1,764 test takers were analyzed using various statistical methods. The revised EPC …
