Over the course of Project Nim, the infant chimp was shuttled between locations and a revolving group of roughly 60 caregivers, including teenagers and grad students, few of whom were proficient in sign language. Four years into the project, Nim became too difficult to manage and was returned to the Institute for Primate Studies in Oklahoma.
After reviewing the results, Terrace concluded that Nim mimicked signs from his teachers in order to get a reward. Terrace argued that Nim did not initiate conversation or create sentences. Terrace said that he had not noticed this throughout the duration of the study but only upon reviewing video tape. Terrace ultimately became a popularly cited critic of ape language studies.
