Degree of lateralization as a hierarchy of manual and cognitive skill levels

C A Miller


Four handedness measures and two cognitive measures were employed with 71 children aged from 3 to 10 yr. Results indicate that high-skill manual tasks become increasingly lateralized and low-skill manual tasks remain in their original, non-lateralized state. High-skill manual task performance correlated significantly with performance on the cognitive measures. Lateralization appears to be directly related to the skill level of the task, for both manual and cognitive tasks.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
