Intellectual Context and Literature Review<br />

2. Intellectual Context and Literature Review<br />

2.1. Background and Recent Research<br />

William Stokoe is known <strong>in</strong> Deaf culture as the “Father of American Sign Language<br />

(<strong>ASL</strong>)”. In his studies of American Sign Language (Stokoe 1960), Stokoe applied the idea of<br />

m<strong>in</strong>imal pairs to reveal the dist<strong>in</strong>ctive parts of a sign. In do<strong>in</strong>g so, he discovered the existence of<br />

three parameters: handshape, movement and location. Eventually, additional research<br />

demonstrated that orientation and a non-manual component were also dist<strong>in</strong>ctive, and these two<br />

parameters were then added. Although the physical form of a sign differs from the physical form<br />

of a spoken word—many of the same phonological processes and pr<strong>in</strong>ciples, such as<br />

assimilation, epenthesis, and metathesis, are found <strong>in</strong> both spoken and signed languages (Padden<br />

and Perlmutter 1987; Liddell and Johnson 1989).<br />

Currently, there are several compet<strong>in</strong>g theoretical models of <strong>ASL</strong> phonology, each try<strong>in</strong>g<br />

to best represent the hierarchical structure, the relationship between the parameters, and the<br />

features with<strong>in</strong> each parameter (Coulter 1992). Liddell and Johnson’s (1989) model proposes<br />

that a sign consists of a sequence of hold and movement segments, somewhat analogous to<br />

consonants and vowels, and each segment conta<strong>in</strong>s specifications for the four parameters.<br />

Movements are segmented <strong>in</strong> Liddell and Johnson’s model.<br />

Dr. Ceil Lucas (1995) has also done studies focused on the sociol<strong>in</strong>guistics of Deaf<br />

communities, <strong>in</strong>clud<strong>in</strong>g issues of sociol<strong>in</strong>guistic variation with<strong>in</strong> signed languages, issues of<br />

bil<strong>in</strong>gualism and language contact, language policy and plann<strong>in</strong>g, and language attitudes. She<br />

has also researched the structure of sign language discourse and is the editor of a journal series<br />

entitled Sociol<strong>in</strong>guistics <strong>in</strong> Deaf Communities, which produces a yearly volume consist<strong>in</strong>g of<br />

papers <strong>in</strong> all areas of sociol<strong>in</strong>guistics perta<strong>in</strong><strong>in</strong>g to Deaf communities from around the world. As<br />

Lucas (1995) notes, Liddell & Johnson’s model is particularly suited for describ<strong>in</strong>g phonological<br />

processes often found <strong>in</strong> variation studies.<br />
