Early number competence, grounded in number-specific and domain-general cognitive abilities, is theorized to lay the foundation for later math achievement. Few longitudinal studies have tested a comprehensive model for early math development. Using structural equation modeling and mediation analyses, the present work examined the influence of kindergarteners' nonverbal number sense and domain-g...

Vaa’ezi Although almost all theoretical perspectives on language development maintain that a relationship of sorts exists between language and general concept of intelligence, the present research looked at this relationship among a random sample of Neyshaaboori preschoolers (4...

Changes in many domains of cognition occur with development. In this paper, we discuss neuroimaging approaches to understanding these changes at a neural level. We highlight how modern imaging methods such as functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) are being used to examine how cognitive development is supported by the maturation of the brain. Some report...

Thirty years have passed since the first report of Acquired Immunodeficiency Syndrome (AIDS) and the subsequent discovery of its etiological agent, the human immunodeficiency virus (HIV) [1,2]. Never before has a single virus been so thoroughly studied, providing vast amounts of data and insight into the intricate complexities of its innate and adaptive immune responses. Despite this knowledge ...
