Giangrande, Evan J.; Beam, Christopher R.; Finkel, Deborah; Davis, Deborah W.; Turkheimer, Eric – Child Development, 2022
This study investigated the systematic rise in cognitive ability scores over generations, known as the "Flynn Effect," across middle childhood and early adolescence (7-15 years; 291 monozygotic pairs, 298 dizygotic pairs; 89% White). Leveraging the unique structure of the Louisville Twin Study (longitudinal data collected continuously…

Linnenbank, M.; Feldmann, R.; Schulte-Körne, G.; Beimdiek, S.; Strittmatter, E. – Journal of Autism and Developmental Disorders, 2022
The processing speed index (PSI) of the Wechsler intelligence scale for children (WISC-IV) has been found to predict a child's level of academic functioning. The consistently reported PSI weakness in children with autism spectrum disorder (ASD) therefore warrants special assistance and attempts at compensation for the disadvantages associated with…

Deckert, Matthias; Schmoeger, Michaela; Schaunig-Busch, Ines; Willinger, Ulrike – Journal of Child Language, 2019
Metaphor development in conjunction with verbal intelligence and linguistic competence in middle childhood and at the transition to early adolescence was investigated. 298 individuals between seven and ten years (chronological age) who attended grades two-four (mental age) were tested for metaphor processing by the Metaphoric Triads Task, for…

Barbosa, Poliana G.; Jiang, Zixia; Nicoladis, Elena – International Journal of Bilingual Education and Bilingualism, 2019
Previous studies showed that bilinguals tend to score lower on some language tests than monolinguals in each of their languages and outperform monolinguals on some cognitive tasks. We investigated whether short-term and working memory capacities that underlie language abilities differ between sequential bilinguals and monolinguals. We tested…

Lopata, Christopher; Donnelly, James P.; Rodgers, Jonathan D.; Thomeer, Marcus L.; Booth, Adam J. – Autism: The International Journal of Research and Practice, 2020
This study assessed the reliability and criterion-related validity of teacher ratings on the Adapted Skillstreaming Checklist for a sample of 133 children, aged 6-11 years, with autism spectrum disorder (without intellectual disability). Internal consistency for the total sample was 0.93. For a subsample, test-retest reliability was very good (r =…

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…

Burger-Caplan, Rebecca; Saulnier, Celine; Jones, Warren; Klin, Ami – Autism: The International Journal of Research and Practice, 2016
The Social Attribution Task, Multiple Choice is introduced as a measure of implicit social cognitive ability in children, addressing a key challenge in quantification of social cognitive function in autism spectrum disorder, whereby individuals can often be successful in explicit social scenarios, despite marked social adaptive deficits. The…

Snowling, Margaret J.; Duff, Fiona J.; Nash, Hannah M.; Hulme, Charles – Journal of Child Psychology and Psychiatry, 2016
Background: Children with language impairment (LI) show heterogeneity in development. We tracked children from pre-school to middle childhood to characterize three developmental trajectories: resolving, persisting and emerging LI. Methods: We analyzed data from children identified as having preschool LI, or being at family risk of dyslexia,…

Mix, Kelly S.; Levine, Susan C.; Cheng, Yi-Ling; Young, Chris; Hambrick, D. Zachary; Ping, Raedy – Grantee Submission, 2016
The relations among various spatial and mathematics skills were assessed in a cross-sectional study of 854 children from kindergarten, third, and sixth grades (i.e., 5 to 13 years of age). Children completed a battery of spatial mathematics tests and their scores were submitted to exploratory factor analyses both within and across domains. In the…

Bannink, Femke; Fontaine, Johnny R. J.; Idro, Richard; van Hove, Geert – International Journal of Educational Psychology, 2016
This study investigates cognitive abilities of pre/primary school children without and with spina bifida in Uganda. Qualitative semi structured interviews and quantitative functioning scales measurements were combined and conducted with 133 parents, 133 children with spina bifida, and 35 siblings. ANCOVA was used to test for differences in…

Vrachimi-Souroulla, Andry; Panayiotou, Georgia; Kokkinos, Constantinos M.; Lamprianou, Iasonas – Educational Psychology, 2011
The study aimed to field-test a Greek version of the Wechsler Quicktest and to examine its psychometric properties. The Quicktest was individually administered to 208 students, aged 5-14 years, along with a reading test. Based on the Rasch analysis, data for the Quicktest subtests showed acceptable fit to the model. Also, correlations were found…

Zhou, Xiaobin; Zhu, Jianjun; Weiss, Lawrence G. – Journal of Psychoeducational Assessment, 2010
This study investigated the Wechsler Performance IQ (PIQ) or Perceptual Reasoning Index (PRI)/ Perceptual Organization Index (POI) change over time and its relation to ability levels. PIQ or PRI/ POI was analyzed because of the known sensitivity of nonverbal scales to the Flynn effect. Scores were analyzed using two methods. First, analysis of…

Geers, Anne E.; Nicholas, Johanna G. – Journal of Speech, Language, and Hearing Research, 2013
Purpose: In this article, the authors sought to determine whether the precise age of implantation (AOI) remains an important predictor of spoken language outcomes in later childhood for those who received a cochlear implant (CI) between 12 and 38 months of age. Relative advantages of receiving a bilateral CI after age 4.5 years, better…

Tabachnick, Barbara Gerson – Journal of Learning Disabilities, 1979
The study was designed to investigate scatter produced by 105 learning disabled (LD) children (6 to 16 years old) and to compare Wechsler Intelligence Scale for Children-Revised (WISC-R) scatter with that produced by A. Kaufman's (1976) normal population. Range of scaled scores (i.e., scatter) was significantly greater for the LD group. (SBH)

Irons, Donna – Psychology in the Schools, 1981
The Wechsler Intelligence Scale for Children-Revised (WISC-R) was administered to (N=72) elementary school children. Compared three methods of pretest rapport establishment for each of two age groups. Results found no significant differences on WISC-R scores as a result of the interaction of age and familiarity conditions. (Author)
