Individual phenotype, kinship, and the occurrence of inbreeding in song sparrows.

2 Dec 2008 Inbreeding load, a key parameter in evolutionary ecology, is frequently estimated by regressing fitness (or related traits) on inbreeding coefficient across population members. This approach assumes that inbreeding occurs randomly with respect to ... Read more...

Investigating children as cultural magnets: do young children transmit redundant information along diffusion chains?

10 Nov 2008 The primary goal of this study was to investigate cultural transmission in young children, with specific reference to the phenomenon of overimitation. Diffusion chains were used to compare the imitation of 2- and 3-year-olds on a task in which the ... Read more...

Age-related changes in motor subtle signs among girls and boys with ADHD.

2 Nov 2008 OBJECTIVE: To examine differences in age-related improvement in motor speed and neurologic subtle signs (overflow and dysrhythmia) among boys and girls with and without attention-deficit hyperactivity disorder (ADHD). METHOD: Diagnosis of ADHD was ... Read more...

Definition: Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
