This is an ongoing project investigating the structures that emerge in newly-formed sign languages (e.g., Nicaraguan Sign Language) across dimensions such as phonology, morphology, syntax, and discourse. Factors including social network size (number and type of interlocutors) and the bi-directional influence of cognition and language are investigated as contributing (or not) to language emergence.
