"Stephen Colbert has brought new words like 'truthiness' and 'Lincolnish' into the lexicon," Marian said. "We had to invent a new language to do our research, and no one invents words as readily as Stephen Colbert. Naming our new language after Colbert was a no-brainer."
Marian said the Colbertian words were designed not to resemble any words in English or Spanish.
James Bartolotti, co-author of the study, said bilingual study participants had an easier time learning the invented language.
"It turns out that skill, once acquired, helps you learn a new language. And that knowledge of another language confers all kinds of benefits," he said.
