Sex Differences in Nonverbal and Verbal abilities in Childhood and Adolescence

Individuals' cognitive abilities can have implications on the quality of their task performance and social behaviors (e.g., verbal communication). Examining differences in cognitive abilities across the sexes can help to better understand the patterns of cognitive development. This study investigated sex differences in cognition by exploring nonverbal and verbal abilities across development in a sample of twin siblings. The findings indicate that sex differences in verbal and nonverbal abilities exist, with distinct variations from ages 2 to 16 years.
