James is one of the rulers reported to have conducted a language deprivation experiment, sending two children to be raised by a mute woman alone on the island of Inchkeith, to determine if language was learned or innate.
Bio je jedan od vladara koji su navodno provodili pokus lišavanja jezika, poslavši dvoje djece na odgoj kod nijeme žene, same na otoku Inchkeith, kako bi utvrdio je li jezik naučen ili urođen.
