What characterizes the Rochester method of signing?

The Rochester method of signing is characterized by its exclusive use of the manual alphabet to represent the English language. This method emphasizes spelling out words letter by letter using fingerspelling, rather than utilizing signs or vocabulary that would convey the meaning of the words in a way that is independent of English structure. This approach is intended to facilitate communication primarily in environments where the focus is on conveying English directly, making the manual alphabet a central feature of the Rochester method.

In context, it's important to consider that the other options do not accurately represent this method. While American Sign Language (ASL) has its own vocabulary and structure, which is different from English, the Rochester method does not primarily incorporate ASL vocabulary. Additionally, the method does not rely on English word structure with signs; rather, it conforms strictly to fingerspelling. The integration of regional dialects does not apply in this context because the Rochester method is more focused on standardized spelling rather than regional variations in signing.
