Individual differences in music traits are heritable and correlated with the development of cognitive and communication skills, but little is known about whether diverse modes of music engagement (e.g., playing instruments vs. singing) reflect similar underlying genetic/environmental influences. Moreover, the biological etiology underlying the…

Aubé, Sophie; Mimeau, Catherine; Gagnon, Eloi; Remon, Alexandra; Brendgen, Mara; Vitaro, Frank; Ouellet-Morin, Isabelle; Tremblay, Richard E.; Boivin, Michel; Dionne, Ginette – Developmental Psychology, 2022
Given the importance of writing for academic achievement, this study aimed to understand how early oral language contributes to later writing skills. The first objective was to determine if preschool language skills were associated with high school writing, and if so, whether they contributed directly or indirectly through school age language. The…

Tucker-Drob, Elliot M.; Reynolds, Chandra A.; Finkel, Deborah; Pedersen, Nancy L. – Developmental Psychology, 2014
Aging-related declines occur in many different domains of cognitive function during middle and late adulthood. However, whether a global dimension underlies individual differences in changes in different domains of cognition and whether global genetic influences on cognitive changes exist is less clear. We addressed these issues by applying…

Finkel, Deborah; Reynolds, Chandra A.; McArdle, John J.; Hamagami, Fumiaki; Pedersen, Nancy L. – Developmental Psychology, 2009
Previous analyses have identified a genetic contribution to the correlation between declines with age in processing speed and higher cognitive abilities. The goal of the current analysis was to apply the biometric dual change score model to consider the possibility of temporal dynamics underlying the genetic covariance between aging trajectories…

Price, Thomas S.; Jaffee, Sara R. – Developmental Psychology, 2008
The classical twin study provides a useful resource for testing hypotheses about how the family environment influences children's development, including how genes can influence sensitivity to environmental effects. However, existing statistical models do not account for the possibility that children can inherit exposure to family environments…

Peer reviewedMather, Patricia L.; Black, Kathryn N. – Developmental Psychology, 1984
Examines genetic influences on language by assessing 158 preschool twins on vocabulary comprehension, semantic knowledge, morphology, syntax, and articulation. Vocabulary comprehension was significantly influenced by heredity, whereas performance skills were influenced by between-family environmental factors. (Author/AS)

Peer reviewedColledge, Essi; Bishop, Dorothy V.M.; Koeppen-Schomerus, Gesina; Price, Thomas S.; Happe, Francesca G.E.; Eley, Thalia C.; Dale, Philip S.; Plomin, Robert – Developmental Psychology, 2002
Language development was studied in 310 pairs of 4-year-old twins. Rotated factor analyses indicated presence of a general language factor (L) and a general nonverbal factor (NV). Moderate genetic influence was found for L and NV abilities. Bivariate genetic analysis estimated a genetic correlation of .63 between L and NV abilities. Results…

Peer reviewedFinkel, Deborah; Pedersen, Nancy L.; Plomin, Robert; McClearn, Gerald E. – Developmental Psychology, 1998
Collected data on twins' performance on 13 cognitive variables measured three times at three-year intervals. Twins were monozygotic or dizygotic pairs reared together or apart and were in six cohorts ranging in age from 41 through 84 years. Found stable mean cognitive performance across time on eight measures for the younger cohorts, and…
