LINGUISTIC DIFFERENCES Phonological: BASL signers are more likely to produce two-handed signs, use an overall larger signing space, and tend to produce more signs on the lower half of the face. Syntactical: A higher incidence of syntactic repetition appears in multiple studies of BASL signers. A study documented in 2011 also showed more frequent use of constructed dialogue and constructed action among Black signers. Lexical Variation: Some signs developed at Black Deaf schools diverge completely from standard ASL signs, mostly for everyday objects and activities discussed frequently by students. Linguists have also noticed an increase in lexical borrowing of words and idioms from African American Vernacular English (AAVE) among younger Black signers. Due to the prevalence of the oral method in white deaf education after the Milan Conference, many white deaf children were denied access to American Sign Language, and ASL was subjugated by spoken English. However, significantly fewer resources were dedicated to Black deaf education, leaving many Black Deaf schools to pursue manual language. As such, scholars note that some variations common in BASL, like a higher incidence of two-handed signs, are actually a preservation of the linguistic qualities of early ASL.

(Jump to “Directory of U.S. Black Deaf Schools.”) Carl Croneberg, a Swedish-American Deaf linguist, was the first person to note differences between ASL and BASL in writing, as coauthor of the 1965 Dictionary of American Sign Language on its Linguistic Principles (see also: William Stokoe). Dr. Carolyn McCaskill’s 2011 book, The Hidden Treasure of Black ASL: Its History and Structure, features data from a series of studies performed by McCaskill and her team, and is considered a foundational work in the field.
