There was a video clip that became extremely popular on the internet that sparked the question that there was a chance twins have their own language. There has always been a question in everyone's minds about twins having their own language. It certainly seems possible since twins are genetic clones of each other.
The first time I saw this video, I thought it was adorable, and the idea that twins could have their own language was fascinating. Psychologists that analyzed the video claimed that the twins were imitating the way they observe their parents communicate, some even claimed that it is possible twins can be communicating in their own language. However, research has shown that the phenomenon known as cryptophasia is only a myth. Cryptophasia has been disputed by research that states it is only a result of phonological impairment and other types of language delay. Since twins are more likely to make the same mistakes in articulation and pronunciation, they will be more likely to understand one another than other people involved in their lives. Even after reading about this research in the Lilienfeld text, I am a skeptic. I still think it is a possibility for twins to form their own secret language. It would only make sense since they share the same exact DNA.
