In 2006, former US president George Bush supported his embattled defense secretary Donald Rumsfeld with the words: "But I'm the decider, and I decide what is best." This quotation quickly entered the folklore of political humour. But to psychology researchers, it revealed something fundamental about human language.

There are several benefits of learning a new language, the latest being it promotes a better understanding (and acceptance of) psychology and diversity.

This review considers speaking in a second language from the perspective of motor-sensory control. Previous studies relating brain function to the prior acquisition of two or more languages (neurobilingualism) have investigated the differential demands made on linguistic representations and processes, and the role of domain-general cognitive control systems when speakers switch between languages.
