Susan Goldin-Meadow

Developmental psychologist at the University of Chicago known for her research on home sign — the self-generated gesture systems deaf children invent when raised without exposure to a conventional sign language. She matters to this vault as the comparison case Ann Senghas's Nicaraguan Sign Language findings are measured against: Goldin-Meadow's own 2011 commentary on Senghas's work, read directly, is what establishes that the Nicaraguan case is a genuinely more extreme condition — no sign language anywhere in the community to be exposed to, not merely no sign-language input at home.
