Processing speed is a component of general intelligence and an indicator of learning potential. There is a need for robust measures of mental speed based on contemporary theoretical developments. The current study addressed this need by proposing a mental speed test for children aged 60 to 96 months (5 to 8 years) and examining its psychometric…

In the development of cognitive science understanding human intelligence and mind, measurement of cognitive ability has played a key role. To address the development in data scientific point of views related to cognitive neuroscience, there has been a demand of creating a measurement to capture cognition in short and repeated time periods. This…

This study examined the factor structure of the Detroit Tests of Learning Abilities, Fifth Edition (DTLA-5) using principal axis factoring, multiple factor extraction criteria, and the Schmid-Leiman orthogonalization procedures not utilized by test publishers. Results suggest that the publisher's six-factor structure model was over factored.…

University achievement is a highly relevant educational outcome with implications for students' academic and professional futures. As the majority of students that drop out of university do so due to subjective reasons in contrast to a lack of capability to handle the workload, a measure of subjective university achievement (complementing grade…

Background/Context: Previous research in educational assessment has consistently emphasized the importance of reliability as a cornerstone of test quality. Traditional measures of reliability, such as test-retest and split-half reliability, offer a broad view of how internally consistent a measure is but overlook the variability in this internal…

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.…

This study aimed to investigate the psychometric properties of the Wechsler-4 Intelligence Scale who are deaf with Mild Intellectual Disability. Descriptive survey method was used. The sample included (174) deaf students in Jordan, ranging in age from (6-16.11) years. The scale was also applied in sign language. Validity indicators were found…

Students with autism spectrum disorders (ASDs) in Saudi Arabia are provided with the educational services they need in their local schools, but a standardized checklist is needed to measure the level of progress and the benefits acquired through the educational programs. This study aimed to standardize a version of Saudi performance norms on the…

Measurement of mental rotation presents a serious challenge to cognitive researchers owing to the lack of a single comprehensive measure that can be applied across the developing age groups. Objective of the present study was to develop and validate a new measure of mental rotation for preadolescent and adolescent age groups. Items were…

Naturalistic developmental behavioral interventions for young children with autism spectrum disorder share key elements. However, the extent of similarity and overlap in techniques among naturalistic developmental behavioral intervention models has not been quantified, and there is no standardized measure for assessing the implementation of their…

Each year many students take college admissions exams (i.e., SAT® and ACT®), hoping to demonstrate their ability to perform at a collegiate level and gain admission to desired universities. However, a growing movement encourages colleges and universities to abandon this practice in their admissions protocol and instead consider alternative…

Assessing job applicants' general mental ability online poses psychometric challenges due to the necessity of having brief but accurate tests. Recent research (Myszkowski & Storme, 2018) suggests that recovering distractor information through Nested Logit Models (NLM; Suh & Bolt, 2010) increases the reliability of ability estimates in…

Peer interaction can be challenging in autism spectrum disorder, but naturalistic peer-observation scales for preschoolers are scarce. This study examined psychometric qualities of the newly developed Autism Peer Interaction Observation Scale. We tested the Autism Peer Interaction Observation Scale to (a) characterize peer interactions of…

This study investigated the psychometrics of a recently developed global rating measure of videotaped parent-infant interaction, the "Manchester Assessment of Caregiver-Infant Interaction" (MACI), in a normative sample. Inter-rater reliability, stability over time, and convergent and discriminant validity were tested. Six-minute play…

In this study, we examined the factor structure, reliability, and external validity of scores from the Comprehensive Test of Nonverbal Intelligence-Second Edition (CTONI-2) using an independent sample of young adults currently enrolled in a postsecondary institution. Although the subtests appear to be measuring general intelligence, the aggregate…
