Agenda
3
The Advisory Committee
  • The Research Centre will have an Advisory
    Committee, to advise the Director on the Centres
    general strategy in order to achieve its aims and
    objectives and also to maximise the outreach and
    impact of its research.

4
Reports
  • Staffing
  • Technical
  • Associated projects
  • Students
  • Summer school taster course
  • Seminar programme
  • Visitors
  • Publications

5
Introduction
6
Introduction
  • Advisory Committee membership
  • Role of the Advisory Committee
  • Structure of DCAL
  • The Centre

7
Research Presentations
8
DCAL Online Participation System
  • Crossgroup team
  • Kearsy Cormier, Adam Schembri, Tanya Denmark

9
Rationale for online system
  • Sign language research typically with small,
    manageable numbers of participants
  • DCAL projects much larger numbers
  • Norming study alone around 100 participants
  • One centralised DCAL database for research
    participants
  • Ethical and data protection considerations

10
Sona Systems
  • Web-based participant pool management system for
    universities
  • Experiment Management System (Sona Systems, Inc.)
  • Typically used by psychology depts (e.g. UCL
    Psychology)
  • Allows confidential storage of info and anonymous
    recruitment
  • Participants are known to researchers with
    numeric ID code only

11
Demos
  • Demo as new participant
  • Pretest (questionnaire), introduction and first
    few pages
  • Demo as researcher
  • Setting up study
  • Pretest qualification analysis
  • Pretest data analysis

12
Cross-group Activities Normative Lexical Data
for BSL ( Assessment Tools for BSL)
  • Dr Adam Schembri

13
Objective
  • To develop a thorough description of the lexicon
    and grammar of BSL through
  • Collection of normative data
  • Assessment tools based on the these data

14
Normative Data
  • We will collect data about the following
    properties of BSL lexical signs
  • Familiarity/rarity of signs
  • How familiar are various signs to BSL signers?
  • Iconicity
  • To what degree do signs resemble what they
    represent?
  • Age of acquisition (AoA)
  • At what age are various signs acquired?

15
Collection of normative data
  • We will collect normative data from BSL signers
    around the UK (at least 100 signers) on
    familiarity, iconicity and AoA for 300 BSL signs.
  • Signers will rate these different dimensions on a
    7-point scale (will show demo of on-line norming
    task)
  • The resulting normative data will be used in
    preparation of materials for testing by
    research groups within DCAL.

16
Target groups for norming
  • All adult signers, aged 18-60
  • native signers who learnt BSL from Deaf parents
  • early signers (e.g., first exposed to BSL aged
    3-5 years)
  • mid-childhood signers (e.g., first exposed to BSL
    ages 9-11 years)
  • late signers (e.g., exposed to BSL after age 15)

17
Norming data What for?
  • Will be used by researchers within DCAL and
    associated projects
  • Language processing group (iconicity,
    familiarity, AoA)
  • Language development group (AoA)
  • Will be used in development of assessment tools
    for BSL

18
Sign language assessment
  • Very few tools for assessing sign language
    competence
  • There are no normed assessments of BSL for adults
    (some for children)
  • Difficult to judge what the norm should be
  • Importance of knowing when signer learned to sign
  • Native signers Only 5-10 of D/deaf population
  • Research on other sign languages has clearly
    shown that varied age of exposure to a sign
    language affects fluency.

19
Development of standardised assessment tool
  • We will create a computer-based BSL assessment
    tool for comprehension of
  • Phonology
  • Vocabulary
  • Syntax morphology
  • Also a computerised production test
  • Sentence repetition task

20
Use of normative data in assessments
  • Target signs in assessment tasks will be balanced
    for familiarity wherever possible
  • Importance of including signs very low in
    familiarity
  • Normative data on iconicity and AoA may also be
    used in developing assessment tools

21
Implications and applications
  • These tools will provide a benchmark for BSL
    competence
  • Within DCAL
  • These normative data and assessment tools will be
    used in most of the 5 research strands within
    DCAL

22
Beyond DCAL
  • The data tools will also be made available to
    other BSL researchers across the country.
  • Will aid in understanding the causes of
    differences between deaf individuals
  • Useful in designing intervention programmes to
    promote better communication and learning in
    various populations
  • Pupils of secondary school age
  • Deaf children and adults with developmental or
    acquired communication impairments
  • First steps to establishing sign therapy

23
Current status
  • Norming study
  • Piloting the set of signs to be normed
  • Ensuring the norming task works for use as an
    online task (will also offer an offline version -
    DVD and rating sheets)
  • Scheduled to begin late September 2006
  • Assessment tools
  • Researching other assessment tools that are
    available
  • Deciding on target linguistic structures to
    assess
  • Deciding on methods, types of task to be used in
    assessment
  • Scheduled for completion late 2007

BSL MacArthur-Bates Communicative Development
Inventory
Tyron Woolfe
25
Current situation in UK
  • British Sign Language evidence but from 3yr.
    onwards
  • There is no evidence base for under 3yr.
  • Parents are therefore subject to worry
  • Audiological evidence
  • Speech evidence
  • Convincing
  • Reassuring

26
The BSL MacArthur-Bates Communicative Development
Inventory (CDI)
  • What it does
  • What it does not do
  • Developing a BSL version
  • Preliminary findings
  • Advantages and Disadvantages
  • Current areas of interest

http//www.sci.sdsu.edu/cdi/cdiwelcome.htm
27
  • What it does
  • Gives an indication as to the average vocabulary
    size that ought to be attained by an age group.
  • Allows monitoring to be objective
  • Alerts for indicators of delays/language related
    disabilities
  • What it does not do
  • Give a definite number of vocabulary
  • Give any insight into morphology
  • Give a comprehensive picture of a childs
    communicative abilities - index

28
Scientific Properties of the MacArthur-Bates CDI
  • extremely reliable, r.96
  • High validity scores (.60 - .80)
  • Has been translated into numerous languages, e.g.
    French, Cantonese, Spanish, Russian and ASL

29
Anderson Reilly 2002ASL MacArthur-Bates CDI
  • 69 deaf children
  • 34 longitudinal
  • Modified from English CDI
  • Reliability r.91
  • Validity .87
  • Variation in vocabulary size
  • 6 vocabulary size groups rather than age groups
    for analysis
  • Nouns, Predicates and Closed Class items

Advantages and Disadvantages of developing the
BSL CDI
  • Easy to monitor
  • Encourages parent-control
  • A useful tool for early assessment and
    intervention planning
  • Widely known
  • Informally seen as a curriculum by some parents
  • Limited application for BSL
  • Lacks other relevant factors e.g. imitation,
    morphological awareness
  • Standardisation difficult to achieve
  • English biased parents
  • Small group size difficult for statistical
    research
  • Validation

45
Areas of interest in relation to CDI data as
per Anderson Reilly paper as well as other
interests
  • Hearing Status
  • Theoretical Hearing children as Bimodal and
    Bilingual
  • Gender
  • Parental education
  • Parental occupation
  • Attitude of signing

  • Cross-group strand
  • Language development
  • Atypical language
  • Face to face communication
  • Language processing
  • The individual and the community

51
Face to face communicationRuth Campbell
  • Studies of speechreading and face actions in sign
    language

52
Two aspects
  • Developing a test of child speechreading
  • with Tara Mohammed and Mairead MacSweeney
  • Experimental studies of face processing in sign
    language - to start in 2007. Possible additional
    collaborators - Olivier Pascalis, Sheffield
    University, John Swettenham, UCL, Brad Duchaine,
    UCL

53
Developing a test of childrens speechreading -
TOCS
  • to assess silent spoken English comprehension in
    deaf and hearing children aged 6 12
  • to inform and extend the language profile of
    children, using a deaf-friendly task and to
    determine the factors that are affected by and
    affect speechreading (literacy? communication?)
  • to inform clinical intervention with children,
    especially where speechreading is a necessary
    skill (CI children)

54
Where we are
  • Dr Fiona Kyle appointed April 2006 (2 years)
  • work to be done in collaboration with schools
    and special units
  • collaboration with SLPTs in London region
    meetings held
  • ethical and CRB clearance gained for the project

55
What we are doing
  • Two strand approach
  • a basic psycholinguistic test of speechreading,
    comprising single words, short sentences and two
    or more linked phrases, with some add ons
    (minimal pair (pat and hat) and prosody
    (question/ statement/ lexical stress)
  • a clinical test for use with SLPTS using
    communication-relevant speech (what is your
    name? point to your toe)

56
format
  • Computer-based display, with natural videoclips
  • Choose picture to match word
  • Software developed in-house.. Displays and
    collects speed and accuracy data for every item
  • Developed from previous test for adults
