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 sources of individual difference in parental Infant-Directed Speech (IDS) is limited and there is a particular lack of research on fathers' compared to mothers' speech. This study examined the predictive relations between infant characteristics and variability in paternal lexical diversity (LD) in dyadic free play with two-year-olds (M…

Di Sarro, Rita; Di Santantonio, Anna; Desideri, Lorenzo; Varrucciu, Niccolò – International Journal of Developmental Disabilities, 2022
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…

Lifshit, Hefziba Batya; Bustan, Noa; Shnitzer-Meirovich, Shlomit – Journal of Applied Research in Intellectual Disabilities, 2021
Goals: This study examined: (a) crystallized/fluid intelligence trajectories of adolescents and adults with Down syndrome; and (b) the contribution of endogenous (health, activities of daily living--ADL) and exogenous (cognitively stimulating leisure activities) factors on adults' intelligence with age. Method: Four cohorts (N = 80) with Down…

Kaufman, A. S.; Salthouse, T. A.; Scheiber, C.; Chen, H. – Journal of Psychoeducational Assessment, 2016
Patterns of maintenance of ability across the life span have been documented on tests of knowledge ("Gc"), as have patterns of steady decline on measures of reasoning ("Gf/Gv"), working memory ("Gsm"), and speed ("Gs"). Whether these patterns occur at the same rate for adults from different educational…

Joseph C. Y. Lau; Emily Landau; Qingcheng Zeng; Ruichun Zhang; Stephanie Crawford; Rob Voigt; Molly Losh – Autism: The International Journal of Research and Practice, 2025
Many individuals with autism experience challenges using language in social contexts (i.e., pragmatic language). Characterizing and understanding pragmatic variability is important to inform intervention strategies and the etiology of communication challenges in autism; however, current manual coding-based methods are often time and labor…

Jewsbury, Paul A.; Bowden, Stephen C.; Duff, Kevin – Journal of Psychoeducational Assessment, 2017
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…

Bathelt, Joe; Koolschijn, P Cédric M. P.; Geurts, Hilde M. – Autism: The International Journal of Research and Practice, 2022
Face recognition is a fundamental function that requires holistic processing. Differences in face processing have been consistently identified in autistic children, but it is unknown whether these differences persist across the adult lifespan. Using event-related functional magnetic resonance imaging, we measured holistic face processing with a…

Pezzuti, Lina; Dawe, James; Borghi, Anna Maria – Educational Gerontology, 2021
The aim of this study is to focus on the verbal stimuli of the Vocabulary subtest of the Wechsler Adult Intelligence Scale -- Fourth Edition (WAIS-IV). To our knowledge, this is the first research to examine whether the abstractness/concreteness and the lexical category of the words in the WAIS-IV vocabulary subtest influence the ability to…

Fitzhugh, Megan C.; LaCroix, Arianna N.; Rogalsky, Corianne – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Sentence comprehension deficits are common following a left hemisphere stroke and have primarily been investigated under optimal listening conditions. However, ample work in neurotypical controls indicates that background noise affects sentence comprehension and the cognitive resources it engages. The purpose of this study was to examine…

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Stoesz, Brenda M.; Niknam, Mehdi; Sutton, Jessica – Canadian Journal of Learning and Technology, 2020
Research has demonstrated that students' learning outcomes and motivation to learn are influenced by the visual design of learning technologies (e.g., learning management systems or LMS). One aspect of LMS design that has not been thoroughly investigated is visual complexity. In two experiments, postsecondary students rated the visual complexity…

Achievement goal theory is one of the major theories of the relationship between learners' perception of learning processes and their academic achievements. The present research was focused on the relationship between learners' goals and the academic achievements of Hebrew-speaking students, who belong to the majority group, and Arabic-speaking…

Peters, Sabine; Van der Meulen, Mara; Zanolie, Kiki; Crone, Eveline A. – Developmental Psychology, 2017
Although many studies use feedback learning paradigms to study the process of learning in laboratory settings, little is known about their relevance for real-world learning settings such as school. In a large developmental sample (N = 228, 8-25 years), we investigated whether performance and neural activity during a feedback learning task…

Davies, Rob A. I.; Arnell, Ruth; Birchenough, Julia M. H.; Grimmond, Debbie; Houlson, Sam – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2017
The effects of psycholinguistic variables are critical to the evaluation of theories about the cognitive reading system. However, reading research has tended to focus on the impact of key variables on average performance. We report the first investigation examining variation in psycholinguistic effects across the life span, from childhood into old…
