This study sought to provide more insight into potential differences in progression of analogical reasoning comparing gifted with average-ability children taking into account age, using a dynamic testing approach, using graduated prompting techniques, in combination with microgenetic methods. The participants were between the ages of 5 and 8 years…

Growth curve modeling provides a general framework for analyzing longitudinal data from social, behavioral, and educational sciences. Bayesian methods have been used to estimate growth curve models, in which priors need to be specified for unknown parameters. For the covariance parameter matrix, the inverse Wishart prior is most commonly used due…

Aggression in early childhood has been found to predict future psychopathology, academic problems, and delinquency. In a sample of 136 mother-child pairs (M[subscript age] = 4 years, 11 months, SD = 11 months, 58% boys) associations among mothers' responding with distress to children's negative emotions, children's emotional control, and…

We examined the effect of a modified dialogic reading intervention on levels of verbal participation and vocabulary growth in nine preschool children with autism spectrum disorder (ASD) using single-case design methodology. Baseline book reading resulted in consistently low levels of verbal participation followed by an immediate increase in verbal…

The purpose of the present study was to determine whether there are visual-spatial gender differences in two-year-olds, to investigate the environmental and cognitive factors that contribute to two-year-olds' visual-spatial skills, and to explore whether these factors differ for boys and girls. Children (N = 63; M[subscript age] = 28.17 months)…

Developmental dyscalculia (DD) is a specific learning disability in mathematics that affects around 6% of the population. Currently, the core deficit of DD remains unknown. While the number sense deficit hypothesis suggests that the core deficit of DD lies in the inability to represent nonsymbolic numerosity, the access deficit hypothesis suggests…

The majority of episodic memory (EM) tests are far removed from what we experience in daily life and from the definition of this type of memory. This study examines the developmental trajectory of the main aspects of episodic memory--what, where, and when--and of feature binding in a naturalistic virtual environment. A population of 125…

Background: Earlier research and clinical practice show that specific language impairment (SLI) is often associated with nonverbal cognitive deficits and weakened skills in executive functions (EFs). Executive deficits may have a remarkable influence on a child's everyday activities in the home and school environments. However, research…

Proponents of dynamic testing have advocated its use as a replacement or addition to conventional tests. This research aimed to investigate the effects of using versus not using a pretest on both the outcome on the posttest and the processes used in solving inductive reasoning tasks in dynamic testing using a graduated prompts training.…

The relationship between IQ, metacognition, and self-perception of quality of life as measured by the Mooney checklist was explored. Participants who were hearing and deaf and hard of hearing (D/HH) were compared using these outcome variables, with gender as an additional grouping variable. Results revealed performances on these measures were…

This study focuses on J. E. Wallace Wallin, who recognised the rights of children with disabilities to receive an education, and who tackled the scientific classification of children and the provision of special classes in the state of Delaware from the 1930s to the middle of the 1940s. This study intends to clarify how Wallin recognised and…

Sex differences in the strength of the relations between mathematics anxiety, mathematics attitudes, and mathematics achievement were assessed concurrently in sixth grade (n = 1,091, 545 boys) and longitudinally from sixth to seventh grade (n = 190, 97 boys). Mathematics anxiety was composed of two facets, one associated with evaluations and the…

Autistic children have problems in cognitive and motor skills areas. This study investigated the effects of motor and cognitive problems on daily living activities and quality of life in autistic children. Thirty-two autistic children were included in the study. Thirty typically developing children were selected as the control group. The Bruininks…

Algebra I is a crucial course for middle and high school students for successful STEM-related coursework. A key issue is whether students should take Algebra I in Grade 8 versus Grade 9. Large-scale policy studies show conflicting results, and there are few (particularly longitudinal) individual difference studies. In the study, 53 students were…

Background: Assessment of intelligence and executive function (EF) is common in complex neuropsychiatric practice. Although previous studies have shown that EF and intelligence are related, it is unknown whether these constructs relate to one another in a similar manner across different ability groups (mild intellectual disability, borderline…
