The goal of the parent grant is to broaden our understanding of how children learn language to be inclusive of deaf children who are learning a sign language to communicate. This is important because it makes theories of language acquisition more inclusive and because deaf children face systemic barriers in accessing and learning language. The aims of the proposed supplement are threefold. First, it offers the PI of the grant training in supporting scientists from diverse background. The training would cover topics including: setting goals and expectations, culturally aware and inclusive mentoring, giving feedback and navigating difficult conversations, and interrupting interpersonal violence. The second aim is to create professional development materials for scientists in ASL. There are many resources to support professional development available for scientists who use a spoken or written language, but very few resources exist in ASL. The PI has developed a host of trainings on a variety of subjects that have been offered in house. The proposed supplement would support filming and publishing these materials in ways that scientists across the country could easily access at any time. The third aim of the proposal is to support postdoctoral training for Kaj Kraus, a queer deaf scientist, who would help carry out Aim 3 Study 6 from the parent grant.
