A Comparison of
Non-Manual Signals Among Hearing, Hard of Hearing and Deaf Signers
Ruth Tamar
Jackson, Rebecca Orton and Peter Un
Introduction
This
research compares non-manual signals (NMS) usage among Hearing informants, Hard
of Hearing informants that are late learners of sign language, and Deaf
informants that are all native signers of ASL.
The results may tell us whether NMS are incorporated into the sign
language of non-native users. This
information would have ramifications. If
non-native users of ASL can be taught NMS, then the education system should
redouble its efforts to make sure that this is done. ASL is not a complete language without the
use of NMS.
Hypothesis
The
hypothesis that we are trying to investigate is in equations (1) - (3) and
summarized in equation (4) in Figure 1 below.
Hearing informants are represented by 'H', Hard of Hearing as 'HOH', and Deaf as 'D'. Hearing informants are defined as those that
are hearing and are late learners of ASL or contact sign. Hard of Hearing informants are defined as
those that have a hearing loss and are late learners of ASL. Deaf informants are defined as those that are
native signers of ASL. The equations
signify the following relative amounts of NMS.
Deaf people drops the least NMS.
Hard of Hearing people drops some NMS.
Hearing people drops the most NMS.
(1) D > H
(2) D > HOH
(3) HOH > H
(4) D > HOH > H (in summary)
Figure 1
- Equations regarding the amount of NMS expected in three groups, Deaf (D),
Hard of Hearing (HOH), and Hearing (H).
This
hypothesis D > HOH > H is basically implying three things. First, the Deaf group is natively skilled in
NMS, and has the most hearing loss.
Second, the Hard of Hearing group is not natively skilled in NMS, and
has some hearing loss. Third, the
Hearing group is not natively skilled in NMS, and does not have any hearing
loss. There is nothing unusual about
this particular hypothesis. It would
only be natural to expect that Hard of Hearing people would become more fluent
in NMS use than Hearing people because they have some hearing loss and as a
result are more visually oriented.
This
suggests that there is a relationship between NMS fluency and hearing
loss. That relationship is that the
degree of fluency in NMS would be indirectly proportional to the degree of
hearing loss. If hearing loss is indeed
a factor, then, by extrapolation, NMS use would never be native-like in the
Hearing or the Hard of Hearing groups.
The Hearing group does not have anything in their favor that would have
helped in becoming fluent in NMS. The
Hard of Hearing group has some hearing loss in their favor in becoming fluent
in NMS. The Deaf group has the most
hearing loss by a matter of degree, and are already natively skilled in
NMS.
Why
We are Examining this Hypothesis
This
hypothesis is saying that NMS can only be learned natively as part of a first
language by people with the most hearing loss.
NMS taught during second language acquisition of sign language would
never become native-like among people with full hearing or with some hearing
loss. Results may confirm that fully
fluent NMS can only be learned natively as part of a first language, or if NMS
fluency can indeed be achieved during second language acquisition of sign
language.
Either
way, NMS should be explicitly taught to sign language students. It is possible that the phrase
"nonmanual signals" is not known to a typical sign language student
with mediocre motivation and limited resources.
That NMS perform grammatical functions in natural sign languages is in
general not widely known (Taub 1997:45).
If signers are unaware of the significance of NMS, there may be a
possible breakdown in communication.
English is explicitly taught to children in public school over many
years as a requirement even for native speakers, but ASL is not. ASL is taught optionally to those students
that want to learn ASL and only for a short time. A student with a heavily vested interest in
ASL would have to strive for many years to learn ASL fluently as a second
language. Even native ASL signers may
not be aware of all the grammatical functions of a natural sign language. Being a native signer or speaker does not
guarantee full knowledge and understanding of that natural language and its
grammar.
Literature
Review
Natural
sign languages, such as ASL, involve not just the arms and hands, but the whole
body and face. Baker and Padden (1978:27-57)
mention that in sign languages, there are five different channels of
communication: (1) hands and arms, (2)
head nods, shakes, and tilts, (3) facial
expressions including emotions, (4) eye gaze and blinks, which will be
described in more detail below, and (5) body posture, torso twisting, or body
shifting which may include stepping to the side. These five channels of communication have
different functions but interact together in concert to communicate the full
meaning intended. For example, Wilbur
(1994:221-240) mentions that NMS produced on the mouth and the lower half of
the face perform lexical or semantic functions.
These so called modifiers provide adjectival and adverbial information
that modifies the meaning of the ASL noun or verb. In contrast, NMS produced on the eyebrows and
the upper half of the face, as well as head nods and body movement, perform
grammatical or prosodic functions (Wilbur 1994:221-240).
Wilbur
(1994:221-240) says that "the prosody of ASL is carried by nonmanual
signals...". In other words, NMS
also perform the some of the same functions as voice inflection. For example, emotions are conveyed through
the voice and on the face as well, but may
not be considered part of the grammar.
Another function of prosody that is part of grammar occurs when a
question is being asked. In spoken
English, the voice rises towards the end of the question. There is parallel NMS in ASL for questions. While a question is being signed in ASL,
raised eyebrows indicates a question is being asked where an answer is simply a
'yes' or a 'no' (Baker-Shenk 1983:76, Liddell 1980:20, Wilbur
1994:221-240). This NMS is called a 'Y/N
question' NMS or just 'question' NMS.
A
question is one type of a sentence. The
function that voice inflection and question
NMS perform applies to the whole sentence syntactically. Individual words and signs perform other
directly assignable syntactical functions like nouns, verbs, adjectives,
adverbs, etc. The functions these words
and signs perform also fall under the syntactical category but as components of
the sentence. There are other categories
that these words and signs could fall under, like lexical, morphological, and
discourse markers. According to Robert
E. Johnson (p.c. 1998), there are four different kinds of NMS: lexical, morphological (or modifiers),
syntactical, and discourse markers. One
possible definition proposed for NMS is a definition based on these categories. For example, NMS are those facial
expressions, head movement, eye gaze, and body shifting that are used to
express lexical, morphological, and syntactical meanings in natural sign
languages or that are functioning as discourse markers regulating conversation.
How
are NMS Categorized?
Lexical
items correspond roughly to the notion of 'word' or 'sign'. Lexical NMS are those found within a single
sign, or produced alone without any associated sign. Morphological items are those that add extra
meaning to other signs or sign phrases.
Morphological NMS are those found in ASL inflections, such as the
protracted-inceptive, unrealized inceptive aspect, and iterative
inflections. Modifiers are mostly mouth
configurations, and could be categorized as lexical (Wilbur 1994:222),
morphological (Baker-Shenk 1983:64, Davies 1983), or syntactical but will be
treated separately. Modifiers are
difficult to categorize because they can perform lexical, morphological and syntactic functions
depending on one's point of view. A
modifier can perform a lexical function by modifying the meaning of a single
sign. But modifiers are usually
considered to be morphological in function.
Modifiers also perform syntactical functions by modifying the meanings
of ASL noun or verb phrases like adjectives and adverbs do. Syntactical components are those ordered
groupings of items required to produce a grammatical well-formed sentence, like
noun phrases, verb phrases, adjectives, adverbs, etc. Syntactical items are different types of
sentence forms such as assertations, questions, conditionals, etc. Syntactical NMS are those NMS that are
required to produce different types of sentence forms, like those already
mentioned for syntactical items.
Discourse markers are those items used by the receiver to regulate
conversation. NMS used as discourse
markers are those NMS produced by the receiver as feedback. These categories of NMS as well as eyeblinks,
other kinds of head nods, eye gaze, and head tilts will be described in further
detail below.
Lexical
NMS
In
ASL, there are a few pairs of signs that are distinguished only by NMS. These
'minimal pairs' are so named because only one feature, in this case,
NMS, has contrastive meaning. Every
other feature of these minimal pairs are identical. Taub (1997:46-48) states that the ASL signs
NOT-YET and LATE only differ in their NMS.
The sign NOT-YET has a NMS of a protruding tongue and headshake, and
LATE does not (Baker 1976, Taub 1997:46-48, Liddell 1980:17-18). Another example of a minimal pair is
UNEXPECTEDLY and WRONG. UNEXPECTEDLY has
NMS of raised eyebrows, widened eyes, and mouth-opening jaw drop, WRONG does
not (Baker 1976, Taub 1997:3).
Clearly, NMS cannot be considered as supplemental to the sign in some
cases. Instead, the NMS is vital to
distinguishing between two otherwise identical signs.
Baker
(1976) mentions a few NMS with no associated signs. MENSTRUAL-PERIOD has NMS of puffed
cheeks. DO-YOU-WANNA-HAVE-INTERCOURSE?
has NMS of a tongue pushing out the cheek.
OH-WHY-NOT? has NMS of the head tilted to the side, a puffed cheek and
then release. OH-DEFINITELY-YES! has NMS
of the head tilted to the side, closed eyes, and the mouth in an 'O'
shape. THAT'S-REALLY-INTERESTING has NMS
of an open mouth, then tightly closed lips, half-closed eyelids, and a slowing
nodding head.
Morphological
Some
ASL inflections also have NMS. For
example, the protracted-inceptive (PI) inflection has a horizontal tongue
waggle in certain cases. This PI
inflection means a "protracted beginning" of the action (Taub
1997:53). If the handshape is an open five
handshape where fingers could wiggle, then that finger wiggling is used instead
of the tongue waggle (Taub 1997:53-54).
Liddell
(1984:257-270) analyzed an unrealized inceptive aspect inflection meaning
"JUST AS (subject) WAS ABOUT TO BEGIN (action)." Liddell found that this inflection has the
NMS which he called 'CURB' (Chest Up Rotate Back) and a forward counter
rotation which may or may not be a variant of CURB. Specifically, the CURB NMS is described as a
torso twist to one side while inhaling, and then freezing at the point where
the chest and shoulders are raised. Eye
gaze is also significant, referring to the object of the action in question
(Liddell 1984:267).
Another
example, currently under discussion by Liddell's ASL morphology class is the
iterative inflection meaning "over and over again" (Klima &
Bellugi 1979:294). One possible
production of this iterative inflection uses head nods and an associated NMS
called STA-STA. This STA-STA NMS is
mouthed 'sta'...'sta' with each head nod downward. These NMS within inflections would fall under
the morphological category since inflections, in general, are considered to be
morphological.
Modifiers
Davies
(1983) mentions that lateral and vertical tongue flapping carries two
associated meanings. The first meaning is intense enthusiasm and
excitement. The second meaning is
extensive time or distance. It is not
clear which of the two different ways to flap the tongue has the first meaning
and the second meaning. According to
Lynn Jacobowitz (p.c. 1998), vertical
tongue flapping is rarely seen, and may mean 'hurry' when used with the sign
LOOK. The horizontal tongue flapping can
be used for both the first and second meanings.
However, it is clear that tongue flapping functions like a modifier.
Liddell
(1980:42-47) also mentions several other modifiers. The NMS 'mm' is described as 'keeping the
lips together and pushing them out without puckering.' This NMS means either 'with relaxation and enjoyment'
or 'normal and proper' depending on the context. The 'mm' NMS can also be used by the receiver
as a discourse marker to indicate that what was being signed was expected and
normal (Baker-Shenk 1983:68).
The
NMS 'th' means lack of control, inattention, unintention, and unawareness
(Liddell 1980:50-52). The NMS 'th' is
produced by pushing the lips out with a protruding tongue into a 'th'
configuration where the upper lip is slightly curled upward, and the head is
tilted (Liddell 1980:50-52). The 'th'
NMS can also be used as discourse marker by the receiver to indicate that the
subject of the conversation is 'really out of it' (Baker-Shenk 1983:68).
The
NMS 'cs' means proximity in either a temporal or spatial way (Liddell
1980:47-50). This NMS 'cs' is described
in great detail:
"...when recency is being
contrasted with a much greater period of time (e.g. not last week - just
recently), the signer's head leans and turns toward the side of the body on
which RECENTLY is being made, and the shoulder on that side (or both sides) is
being pulled forward and raised; the facial expression is also made more
intense by a greater contraction of the same facial muscles...all this activity
brings the cheek and shoulder closer together (hence the notation
'cs')."(Liddell 1980:47)
The
facial expression referred to in this quote is similar to what happens to the
lips when talking out of the side of
your mouth.
Syntactic
NMS
Wilbur
(1994:221-240) noticed that the eyebrows perform syntactic functions for
most sentence structures in ASL, except
for assertations (or declaratives).
Wilbur did not mention another sentence structure, negation, in her
research which may involve the eyebrows as well. Assertations have mostly head nods associated
with them (Baker-Shenk 1983:82).
The
yes/no question has NMS of raised eyebrows, widened eyes, head tilt forward,
torso shift forward, and eyegaze to the receiver (Baker-Shenk 1983:76, Liddell
1980:20, Wilbur 1994:221-240). The
rhetorical question has NMS of raised eyebrows, head tilt, and eyegaze to the receiver (Baker-Shenk
1983:79, Wilbur 1994:221-240).
The
topic part in topicalized sentences has NMS of raised eyebrows, slight backward
head tilt, and constant eyegaze to the receiver (Baker-Shenk 1983:88, Liddell
1980:22, Wilbur 1994:221-240). The 'if' portion of the conditional has NMS
of raised eyebrows (or squinted under some circumstances), head tilt, and torso
shift (Baker-Shenk 1983:90, Wilbur 1994:221-240).
Wh-questions
are those questions asking who, what, where, when, why, and how. The wh-questions has NMS of squinted
eyebrows, head tilt, torso shift forward, and eyegaze to the receiver
(Baker-Shenk 1983:78, Wilbur 1994:221-240).
Negation has NMS of squinted eyebrows, side-to-side headshake, wrinkled
nose, raised upper lip, and a frown (Bahan 1996:340, Baker-Shenk 1983:80).
Liddell
(1980:23) found that there are indeed restrictive relative clauses in ASL. A restrictive relative clause is a form of
syntactic subordination of sentences.
These relative clauses have NMS associated with them: brow raise, head tilted back, and raised
upper lip.
Discourse
Markers
Discourse
markers are those things the receiver says or does as back channel feedback to
indicate the receiver is understanding the signer while the signer is talking
or signing at the same time. Examples of
spoken discourse markers are when an English speaker nods and says 'uh-huh',
'hmmm', 'really?' or 'yeah?'. Examples
of manual ASL discourse markers are OH-I-SEE (a nodding Y hand), KNOW, and
REALLY (Collins & Petronio 1998:22).
Examples of NMS used for back channel feedback are head nods, head
tilts, brow raises, and nose-twitching in UH-HUH (Baker-Shenk 1983:68, Collins
& Petronio 1998:3).
Eyeblinks
In
the proposed definition, eyeblinks would not be considered NMS even though they
do have linguistic functions. For
example, boundary eye blinks mark the end of ASL syntactic phrases. In the linguistics field, these syntactic
phrases are called 'ungoverned maximal projections' (Wilbur 1994:221-240). Eyeblinks also function as cues for the
receiver to pay special attention to, for example, the fingerspelling of
"difficult or unusual" words (Wilbur 1994:221-240). Eyeblinks may function as emphasis to lexical
signs themselves. Statistics show that
eyeblinks during lexical signs last longer than those marking boundaries
(Wilbur 1994:221-240). However, blinking
in general is affected by a variety of physiological, perceptual, emotional,
cognitive, as well as linguistic functions (Wilbur 1994:223). Eyeblinks will be excluded from our study
because they are not under complete and solely linguistic control.
Head
Nods
Two
types of head nods are considered to be NMS that are labeled as "_hn"
by Liddell (1980:29-38). The first type
is used for emphasis, and the second type as an existential predicate where
there is a subject with no verb in a main clause (Liddell 1980:29-38). Liddell mentions other types of head nods
used for other functions and these are described as follows. A head dip or slight lowering of the eyes are
used in an affirmative response to a question. A head dip is also used to
indicate a first person subject in a sentence with no overt subject (Liddell 1980:27,
Stokoe 1960:64).
Rapid
slight head nods are used to insert a parenthetic clarification regarding the
subject in the middle of the sentence.
Linguists call such clarifications 'appositives' or 'reduced
nonrestrictive relative clauses' (Liddell 1980:24-25). This kind of head nod distinguishes between
appositives (with head nods) and possessive statements (without head nods) in
ASL that are made typically in English with an apostrophe 's'.
Two
other kinds of head nods are fast head nods to assert something is true when it
has been claimed that it is not, and those emphatic head nods appearing inside
clauses (Baker-Shenk 1983:86-87, Liddell 1980:27-29). These kinds of head nods are often
accompanied by tight lips which also emphasizes that something is true, or
indicates that 'I really mean it' in commands (Baker-Shenk 1983:85-86).
Another
kind of head nod is used for role playing and has other associated
features: nonneutral facial activity
maintained and no eye contact (Liddell 1980:25-26). This kind of head nod is used when the signer
first takes on a role. This head nod
serves as a signal and occurs after the person being role played (or imitated)
is named.
Eye
Gaze and Head Tilts
Baker-Shenk
(1983:74) found that eyegaze and head tilts play a role when setting up
referents in space, and when making pronominal or deictic references to these
spatial locations. Bahan (1996)
researched these two referential types of NMS and found that they perform specialized referential functions in
ASL. That is, the default subject is
referred to when the head is in neutral position. An overt subject is referred to when the head
is tilted. The object is referred to
with eye gaze. Other associated NMS like
body lean, eye gaze, etc. also indicate subject and object referents with
regard to classifier predicates.
Methodology
Each
member of the research team was responsible for one category of informants of
which there were three; hearing informants, hard of hearing informants that are
late learners of ASL, and deaf
informants that are all native signers of ASL.
Each team member obtained permission to videotape the clients,
videotaped them and had them fill out a survey.
Each informant had an ASL competency of at least level 5, as designated
by Gallaudet University in ASL evaluations.
For
gathering data, we began with a survey which obtained information regarding if
the informant could participate, demographic information, family background,
signing experience, and any other considerations they felt were important in
regards to their signing skills.
Regarding
the survey requirements we asked what level of ASL the informant was evaluated
at. We also asked what level of English
literacy was achieved in school as well as the level of formal schooling
achieved. The main reason for these specific
survey requirements was to ensure that clients would be able to comprehend both
the ASL story and the English book used for the research.
Demographic
information which we obtained included place and year of birth, type of hearing
loss if any, region of the US the clients are from, and type of schooling
received. The reasons for requesting
this demographic information were the following. First, to establish what type of effect the
schooling received, age, and regions may have on NMS usage. A student would be more exposed to sign
language at a residential school for the deaf rather than at a public
school. The age may indicate a
generational effect. Regions may have an
impact especially if certain regions do not teach sign language students about
the use of NMS. Second, to see if the
type of hearing loss, if any, has an effect on NMS usage. For example, a person with hearing loss may
be more visually oriented and more likely to notice NMS use.
Within
the survey we requested information regarding the informant's family background
with regards to hearing loss and use of sign language. The specific issues
were, the number of not fully hearing people in the informants family,
including the informant. We also asked
the informant to note if family members used sign language to communicate and
if so, whom? The usefulness of family
background information is to establish if the informant was exposed to sign
language at an early age and possibly a native signer, and to see if sign
language was used as a first language or a strong second language in the
informant's household.
The
next question asked was in reference to signing experience. The goal of this question was to find out what
labels the informants use to identify their sign language (ASL, contact sign,
MCE, etc.). There may be differences in
the usage of NMS in each type of sign language.
Plus, this information would assist in determining if the participants are native signers. We requested responses to the following
questions; type of signing used, year
first learned to sign, length of time signing, whether the informants signed continuously or intermittently, where
they learned to sign, and we asked if the informants remembered any ASL
teachers telling them what NMS were and to pay attention to them.
Lastly,
we gave the informants an opportunity to add anything that they believe might
affect the study of her/his sign language.
Using
the videotapes made, we compared usage of NMS for each informants. Each subject was videotaped while signing a
prerecorded ASL story called, "Exploring A Cave" and a written
English story, "Frosty the Snowman" which have potential for the use
of NMS. We attempted to control all the
factors so that only NMS are variable.
We did not want to use conversations, nor have differences go by
unaccounted for due to lack of fluency in written English or ASL.
We
will look at the NMS within three categories.
The first category is Grammatical Structure: Conditionals, Rhetorical Questions (both Y/N
and WH-), Y/N Questions, WH-Questions, Topicalization, relativation, negation,
etc. as established by ASL 5 classes at Gallaudet, and published sources. The second category is Modifiers: mm, CHA, SMA, LGE, cs, tongue wiggle, open
mouth, puckered lips, puffed cheeks, tightly clenched lips,
"intense", sucked cheeks, etc. as established by ASL 5 classes at
Gallaudet, and published sources. The
third category is Individual Signs that have an associated NMS, like NOT-YET,
etc. as established by ASL classes at Gallaudet. Published sources have been spotty regarding
this area.

Please
look in Appendix 2 for a detail listing of the survey responses. Listed below are data that was considered
significant in our analysis.
Hearing
Group
Female
Hearing Informant 01 and Female Hearing Informant 02 learned NMS through
classes. Both had personal commitment to
learn to sign.
Deaf
Group
No
one explicitly taught Male Deaf Informants 03 and 04 how to use NMS. The NMS were acquired natively.
Hard
of Hearing Group
Female
HOH informant 05 knew some NMS, specifically MM, OO, and CHA. She mentioned that she improved her NMS
through a level 5 ASL class. She wants
to improve her sign language to be like native Deaf people.
Female
HOH informant 06 did not know anything about NMS. (We noticed her lack of knowledge directly
from her videotapes). It seemed that her
NMS were inconsistent and changed rapidly.
She stated that she prefers not to improve on her sign language; but use
the skills she has developed.
Videotape
Data
To
measure the usage of NMS, we chose certain concepts from the book and video
which we felt would have NMS.
Analysis on the NMS used in the book,
"Frosty the Snowman" is based on four concepts. 'Magic' and 'Joyful' were actual words found
in the book. 'Role-Play' is where the
signer takes on the role of Frosty when the book refers to the utterances by
Frosty: 'I'm Frosty the Snowman!' and
'I'll be back when the next big snow falls!'
Role-shifting may be included as part of the NMS for role-playing. 'Play' was implied through English and
pictorial description of the children ice-skating and playing with Frosty
within the book. See Figure 2 below for
the associated NMS with these concepts.

The
analysis of the total number of NMS recorded as seen in the TOTAL line on the
chart in Figure 4 are inconclusive because all the groups have similar
amounts. No conclusions can be drawn
other than all the groups are capable of producing some NMS while signing the
story from the book. However, the
analysis of the total number of NMS recorded as seen in the TOTAL line on the
chart in Figure 5 is that the result
appears to be H > D > HOH. If the
data from the first chart in Figure 4 are added, this result would still be the
same. The interpretation of the equation
H > D > HOH is that the Hearing
group drops the least NMS, Deaf group drops some NMS, and the Hard of Hearing
group drops the most NMS.
Our
hypothesis, D > HOH > H was not confirmed from our data. The result we have found, H > D > HOH,
has the following implications. The
Hearing group is not natively skilled in NMS, however retains the use of
NMS. The Hard of Hearing group also is
not natively skilled in NMS, and seems to eliminate many NMS in their signing
and the Deaf group is natively skilled in NMS and seems to eliminate some of
the NMS in their signing. Hearing loss
is not a significant factor in becoming fluent in NMS for the Hard of Hearing
or Hearing groups. NMS use can become
native-like in the Hard of Hearing and Hearing groups.
Data
Collection Issues
We
were unable to determine the effects of regions on the amounts of NMS between
the three groups because of insufficient number of informants representing each
general region, like the East Coast, Midwest, and West Coast. Analysis was subjective based on our
collective opinion as to if a NMS was seen or not. Decisions to measure NMS were difficult. Sometimes a portion of a NMS was seen and we
choose to say only 'Yes' or 'No' so the answer would be "Yes" if even
a portion of a proper NMS was observed.
The research was skewed based on the opinions of what would or should be
found. We only observed certain
portions. Perhaps if more data was
analyzed the results would be different.
Another issue is that NMS seem to be personally adjusted by each
informant depending on personality, who
signing with, regarding what, etc. It is
questionable that NMS can be measured
with so many possible varying factors.
It's
possible that native Deaf signers have different use of NMS, as do late signers
who are HOH and Hearing. It may be
difficult to compare the three groups because usually Deaf of deaf grow up with
ASL as their native language. All other
people do not have ASL as a native language.
It is difficult to compare non-native signers with native signers. Also, it is natural for people to think that
the native deaf signers use NMS correctly; but does that mean that any
deviation is incorrect or non-usage?
This is a subject that may need further research. But first it must be decided how one can
research more precisely NMS use differences between Deaf, Hard of Hearing or
Hearing informants. It would be
interesting to compare a CODA (Child Of Deaf Adults) to a native Deaf signer and see if their NMS
matched.
Analysis
of Data from Hearing Informants
We
believe that hearing signers of natural sign language can learn to use NMS in
many ways, for example, through being taught NMS in sign language classes,
socializing with native users of sign language, etc. However, not all NMS that we looked for were
found. We can state that they can learn
NMS but do not have perfect grasp of how and when. We also think that hearing informants have
the most NMS due to a possible tendency to make sure all NMS are produced in
their sign language, a notion similar to hypercorrecting. The Hearing group may be trying to produce
all NMS applicable while some applicable NMS are dropped within the Deaf Group
because the Deaf group is more relaxed and confident in using NMS within their
native language.
Analysis
of Data from Deaf Informants
They
acquire natural sign language as a native language at an early age. We noticed that the deaf informants used the
same NMS with regard to the "anxiety" and other signs when we
videotaped them at different times. Please note that NMS varied a lot among all
the informants. We think that it is
possible that some NMS were missed due to gender differences. The two Deaf informants were male, the rest
of the informants were female. One
other possible explanation is that NMS are dropped because the content is clear
without them in a Deaf Culture context.
Analysis
of Data from Hard of Hearing Informants
We
agree that the low occurrence of NMS in this group could be due to the fact
that the informants are not aware of the need and use of NMS and they are not native
signers. However, we see some usage of
NMS and we could credit this to hard of hearing people being more visually
aware than hearing people in general.
However, the finding H > D > HOH has an implication that hearing
loss is not a factor in learning to use NMS to the point of native-like fluency
because the Hearing group has more NMS than the native Deaf group. The HOH and Hearing groups are not
native. Some other factor, not hearing
loss must be chosen to explain this result.
Maybe this other factor could be a strong motivation to learn sign
language as indicated by the data in the survey. One HOH informant had low amounts of NMS and
low motivation to improve on her sign language.
The other HOH informant had relatively high amounts of NMS and high
motivation to improve on her sign language.
Conclusion
Our
hypothesis, D > HOH > H was not confirmed from our data. The data we gathered shows H > D >
HOH.
Results
clarified that NMS can be taught during second language acquisition and not
just be learned natively as part of a first language. Results showed that second language users of
ASL can benefit by knowing that they need, as a whole, to spend extra time
working on mastering NMS, if possible, and at that level of ASL fluency. Results demonstrated that native users of
sign language should realize that they may not understand non-native users
because of misuse, underuse, different use, or no use of NMS. Results enable us to declare that on a
rudimentary level, NMS are needed to produce comprehensible ASL.
Implications
These
results may enable ASL teachers to see what types of training in NMS is
necessary for HOH or Hearing students to have so that they are fully understood
by the Deaf students. Being taught NMS
appears to be very beneficial for both the Hearing and HOH groups and could be
beneficial for the Deaf group as well.
If ASL was taught to Deaf people, what would ASL look like as a
result? According to Kannapell
(1989:191), deaf informants in her study favor the idea of students taking a
language course in their native language for various reasons, including
learning ASL in depth. In such a course,
NMS would need to be explicitly taught.
