  • Language is not an isolated sphere of activity
    but our fundamental human instrument for dealing
    with the world.

  • Auditory processing skills and speech perception
    are foundational skills for the emergence of
    phonemic awareness and in the broader sense
    phonological awareness important argument for
    anyone working with kindergarten through 6th
    graders www.nationalreadingpanel.org/Press/press_r
    el_4_13_.htm
  • Language processing skills are the foundational
    skills related to following directions,
    comprehension of academic content (whether
    presented verbally or in text)
  • Both these skills are important building blocks
    to literacy important for anyone working with
    children

5
In a childs world, its important to have solid
auditory processing and phonological awareness
skills because
  • From preschool 2nd grade, children are
    learning to read
  • From grade 3 and above, children are reading to
    learn

6
Equally important in the early elementary school
years
  • A child must learn to listen in order to LISTEN
    TO LEARN!
  • Geffner Ross-Swain, Auditory Processing
    Disorders Assessment, Management and Treatment,
    2007, pg.154

  • auditory processing skills and speech perception
    are foundational skills for the emergence of
    phonemic awareness and in the broader sense,
    phonological awareness.
  • These skills are important building blocks to
    literacy.

8
For the sake of todays conference, we shall use
the following processing definitions for
reference purposes
9
Auditory Processing definition (ASHA, 2005, p2)
  • a deficit in the perceptual processing of
    auditory stimuli and the neurobiological activity
    underlying that processing
  • The evaluation is often a bottom-up approach,
    analyzing the childs ability to transfer the
    acoustic signal via the peripheral hearing
    system, CANS and ending in the upper cortex
    (ASHA, 2005 Chermak, 1998 Chermak Musiek,
    1997)
  • Treatment however often takes a top-down
    approach, in which metacognitive and
    metalinguistic strategies are explicitly taught
    to minimize the impact of the processing deficit
    on the listeners life (Bellis, 2003 Chermak,
    1998 Ferre, 2006)

10
Research has outlined the problems with
separating auditory processing into distinct
clinical entities
  • Lubert (1981) stated that the impairment in the
    ability to detect acoustic features of the
    auditory signal was the primary difficulty
    preventing children from performing higher level
    language tasks.
  • Leonard (1998) felt a message had to be
    acoustically and phonetically received and
    retained before meaningful interpretation and
    analysis could occur.
  • Multiple authors and resources over time have
    indicated that auditory processing encompasses a
    variety of auditory and language abilities, and
    is not a simple discrete skill that is easily
    isolated and defined (Gail Richard, chapter 8
    Language Processing vs. Auditory Processing in
    Geffner Ross-Swain, 2007)

11
Language Processing definition
  • Begins at a very concrete level such as noun and
    verb labels, but progresses into experiential
    concrete then into abstract conceptual language.
    Early levels attach meaning to the acoustic
    signal but then refine itself to nuances of
    suprasegmentals of speech (e.g. prosody,
    inflection, timing, etc) Thus, linguistic
    knowledge interpretation of words spoken, but
    meaning changes based upon HOW the verbalization
    was spoken according to acoustic overlays
    (sarcasm, etc.)
  • Gail Richard, ch. 8 in Geffner Swains APD
    book, 2007

12
Auditory processing and Spelling Skills(When
the Brain Cant Hear, Teri Bellis
  • Spelling relies heavily on how we hear sounds,
    and thus in early grades invented spelling is
    encouraged, like in this emerging phonics-based
    spelling example

13
(Developmentally appropriate errors)
  • My favrit pursun in the wurd is my mom. She koks
    for me and I luv the peesa with peprone on it. I
    luv my bruter, but he ets my peesa and I hit him.
    I haf to go to im owt win I hit my bruter. I
    dont like time owt.

14
Invented Spelling samples can provide great
clinical insight into how a child hears the
sounds of speech.
  • A CHILDS INABILITY TO PERFORM INVENTED SPELLING
    AT A YOUNG AGE MAY BE AN EARLY RED FLAG OF AN
    AUDITORY PROCESSING DISORDER.
  • Look for auditory decoding errors reflected in
    spelling, especially for b, d, g, p, t, k.

15
Spelling sample from a 2nd grade girl with
left-hemisphere, speech-sound-based APD or
Auditory Decoding Deficit...same text as
presented earlier.
  • My vavd besn ina wud is my mum. She kig fr me anI
    luv the bese wit brone ont. I luv my bute bu het
    my pese anI item. I af tigo tenod hin I et my
    bute. I dun-lit tenod.

16
APD and Reading
  • An excellent reference to peruse regarding the
    current debate of sensory bases of reading and
    language disorders can be found at
  • www.essex.ac.uk/psychology/symposium2001

17
Speech-Specific Hypothesis cont.
  • This asserts that the processing deficits are
    specific to speech, arising from the difficulty
    of identifying the phonological categories of
    similar phonemes rather than from deficits in
    either the temporal order judgment or the brief
    acoustic changes of formant transitions (Mody et
    al., 1997, p 220)

18
Variability between and within studieswhat does
it mean?
  • Little agreement in the literature (as
    exemplified by the Essex symposium abstracts)
    which hypothesis is correct, and therefore
    recommendations for treatment are limited and
    varied at best.
  • As D.V. M Bishop (University of Oxford, UK)
    summarizes, It seems that no sooner does one
    research group publish a finding demonstrating
    perceptual deficits than another publishes a
    failure to replicate.

19
Is it Temporal Processing?
  • The temporal deficit hypothesis suggests that
    persons with developmental dyslexia have sensory
    impairments, which involve the processing of
    rapidly changing acoustic information such as
    that encountered in formant transitions.
  • This deficit is thought to affect the development
    of reading by disrupting the normal acquisition
    of phonological representations critical for
    sound-grapheme associations

20
Principal Auditory Components of Temporal
Processing
  • Temporal integration duration and intensity of
    the stimuli
  • The perception of temporal order (TOJ) rapidly
    presented linguistic and nonlingustic stimuli
  • Short-term memory - necessary to recall elements
    in sequence (Jutras Gagne et al., 2003)
  • Temporal resolution interval between two
    consecutive stimuli, may include gap detection,
    masking level difference, detection of amplitude
    modulation, detection of temporal
    asynchronization (Moncrieff, 04)

21
Developmental Dyslexia
  • Developmental dyslexics, individuals with an
    unexplained difficulty in reading, have been
    shown to have deficits in phonological processing
    the awareness of the sound structure of words
    and more fundamental deficits in rapid auditory
    processing.

22
Definition of Dyslexia The International
Dyslexia Association, (2002)
  • Dyslexia is a language based learning disability.
    It accounts for approximately 85 of all people
    with a learning disability. Dyslexia refers to a
    cluster of symptoms resulting in people having
    difficulties with specific language skills,
    particularly reading. Students with dyslexia may
    experience difficulties in other language skills
    such as spelling, writing and speaking.

23
Auditory and Visual Processing (Multisensory)
  • Children with dyslexia often exhibit weaknesses
    in auditory and/or visual processing. They may
    have weak phonemic awareness, meaning they are
    unaware of the role sounds play in words. They
    have difficulty rhyming words, blending sounds to
    make words, or segmenting words into sounds.

24
  • Knowledge of letter-sound associations, which
    include letter sound recognition, letter sound
    recall, and the ability to print a given letter
    sound, has been identified by Duncan and Seymour
    (2000) as the best indicator, in the early school
    years, of later literacy.
  • Additionally, reading fluency is related to
    applying the recognition of auditory cues to the
    grammatical markers contained in the text being
    read.

25
  • In spite of the neurobiological and genetic
    influences on dyslexia, there is a biological
    basis for the disorder. Neuroimaging data
    indicate that brain processes related to sound
    structure of language are disrupted in dyslexia.
  • Disruptions in both phonological and auditory
    processing in dyslexia are linked to
    abnormalities in neural processing.
  • (Donna Geffner, ASHA 2004 presentation)

26
  • Shaywitz et al., (1998) using fMRI found
    decreased activity in temporoparietal
    regions-superior temporal gyrus and angular
    gyrus, during phonological processing of both
    letter and pseudo rhyme.

27
Neurology
  • An fMRI study by Bernal Altman (2003) included
    17 abnormally delayed speech children and 35
    age-matched children without delayed speech.
  • The preliminary results indicated that children
    with unusually delayed speech tended to have
    higher levels of right brain lobe activity than
    children without delayed speech, who tended to
    use the left side of their brains when they
    listen.

28
Neuroimaging of Rapid Auditory Stimuli
  • Event related potentials suggest that neural
    processing of rapid auditory stimuli is disrupted
    in dyslexics. During fMRI, rapid and slow
    temporal changes characteristic of speech
    nonlinguistic syllables, were presented.
  • Dyslexic adults showed a disruption in the neural
    response to rapid auditory stimuli.
  • Temple et al., 2001

29
  • Brain imaging scans of the children who
    participated in training showed that critical
    areas of the brain used for reading were
    activated for the first time and began to
    function more normally. Additional regions of the
    brain were activated in what researchers believe
    the dyslexics use as a compensatory strategy as
    they learn to read more fluently.
  • Training that can aid decoding skills, reading
    fluency and comprehension will be discussed next.

30
ALL CHILDREN NEED PHONOLOGICAL AWARENESS SKILLS
TO BE SUCCESSFUL READERS AND SPELLERS, AND WILL
BENEFIT FROM CURRICULA THAT TEACH PHONOLOGICAL
AWARENESS.
31
The role of auditory processing metalinguistic
skills in learning how to read and spell
  • The ability to segment words into syllable and
    phonemes requires auditory processing and speech
    perception skills to be intact.
  • Auditory processing of sound and speech
    perception are FOUNDATIONAL skills for the
    emergence of phonemic awareness.

32
Non-speech acoustical must be taught in
association with grammatical markers!
  • Increase comprehension of conversation and text
    by using books on audiotape/CD. Point out the
    correspondence between grammatical markers to the
    speakers inflection and pauses commasbreath,
    period pause, questionsraise pitch,
    exclamationintensity/stress

33
Metalinguistic Overlays
  • Non-speech acoustical cues that can change
    meaning of a message presented auditorily in
    conversation, or through sentences being read
  • Prosody inflectional cues can indicate
    questions vs.exclamation points vs. periods at
    the end of a sentence, etc. APPLYING these cues
    by the reader provides greater fluency to the
    text being read, and often greater comprehension.
  • Rhythm can completey change word meaning REcord
    (object) vs. reCORD (verb)
  • Stress can impact KEY word understanding
  • intonation can indicate sincerity or sarcasm
  • Segmenting can change word meaning They saw the
    CARGO on the boat vs. They saw the car go on the
    boat!

34
Auditory Training for Metalinguistic cues
  • Detection of SILENCE/PAUSE
  • Discrimination of pitch patterns,
    intensity/temporal cues associated with sentences
    heard or text read
  • Vigilance (noting when stimuli change)

03/10/07
35
Temporal Gap Detection
  • Ask the child to detect brief gaps inserted
    within brief bursts of white noise which are
    progressively shortened approaching criterion of
    1 - 5 msec of gap detection.
  • Use audiometer or even a childs electronic
    keyboard for stimulus presentation
  • can use tape recorded samples or present live,
    realizing the poor temporal validity

03/10/07
36
SOUND DISCRIMINATION (whether 2 stimuli are
same/different)
  • Frequency Differences
  • Discern pitch differences of approx. 5 - 10 Hz
  • can use available programs (Earobics Step 1
    Farmer Fardell, Away We Go (Scientific Learning
    Corp Spaceship)
  • OR audiotape tone sequence of 2 notes presented
    in series of 3, from your audiometer or even
    piano and use in therapy

09/16/98
37
DISCRIMINATION (cont.)
  • Tone Glide Discrimination
  • NORM identification of durations of only 1 - 2
    msecs
  • Determine the upward or downward direction of a
    fundamental frequency sweep for tone bursts of a
    few msecs.
  • Initially, the clinician can simply whistle
    sweeps, but as accuracy improves, will need more
    valid stimuli from audiologist

09/16/98
38
DISCRIMINATION (continued)
  • Temporal tone order discrimination
  • tones with durations of approx. 25 msec,
    presented with audiometer or keyboard
  • listener task is to discriminate tone order
  • e.g. High - low - low
  • child can use colored poker chips to represent
    the High vs. low tones, which removes verbal
    components from the task

09/16/98
39
Video exampleHigh/Low tone presentation
  • 2nd level of pitch pattern discrimination

40
Live presentationAudience Training of pitch
pattern application
  • Pitch rising question mark or exclamation mark
  • Pitch lowering period/statement

41
Live audience training
  • Book on audio-tape/CD listening for pause in the
    text being read to child, and indicating by a
    hand/finger raise when pause is recognized.WHILE
    text is seen

42
Continue auditory accuracy of pause
identification step 2
  • NOW, xerox several pages from the book being read
    on tape, but white-out all grammatical markers.
  • Have the child listen for ONE metalinguistic
    overlay at a time (e.g. pause to indicate
    sentence end, while looking for a capitol letter
    to follow CHILD PLACES PERIOD ON XEROXED PAGE
    WITH COLORED PEN/MARKER.
  • Lastly, turn off tape/CD, and compare childs
    grammatical markings to those of the actual text.

43
Videotape example of reading application of pitch
changes
44
Vigilance (sustained attention)
  • Listener required to sustain attention to a
    continuous stream of auditory stimuli (such as
    environmental sounds, syllables, or words) and
    respond (e.g. raising hand or tapping table) when
    a particular target stimulus is heard (e.g.
    Earobics Step 2 Hippo Hoops)
  • Failure to detect inattention
  • False positives impulsivity

Metalinguistics moves into Language Therapy
  • Discourse Cohesion Devices
  • Schema Theory and Use
  • Content Schemata
  • Formal Schemata
  • Schema Induction

09/16/98
46
Language Therapy(CAPD New Perspectives
inManagement Chermak Musiek, 1997, p.192 - 199
  • Discourse Cohesion Devices
  • Referents (pronouns, pro-verbs, comparatives)
  • Pronouns Susan heard a noise. She was
    scared by it.
  • Pro-verbs The hurricane hit land. When it
    did, the whole town was under water.
  • Comparatives Luke loves to play football
    similarly, Kyle love to skateboard.
  • Substitution The class designed a fuel pump. The
    parents were not surprised by their childrens
    ingenuity.

03/05
47
Discourse Cohesion Devices cont.
  • Ellipsis Kerianne loves listening to Ray
    Charles. Her mom does too.
  • Conjunctions
  • ADDITIVE (and)
  • CAUSAL (therefore)
  • TEMPORAL (before, after, during)

48
Cont. with language strategies
  • Schema Theory and Use (a set of expectations
    stored in memory that preserves the relations
    among concepts/knowledge about a situation,
    event, or situation) Children show this ability
    as young as 2 to 3 years (Nippold, 1988)
  • Content Schemata (scripts for events related to
    content) The punter kicked the ball vs. the
    golfer kicked the ball.

49
  • Formal Schemata (linguistic markers that
    organize, integrate and predict relationships
    across propositions, but they do not specify
    meaning) Include conjunctions and correlative
    pairs (not only/but also, neither/nor)
  • Schema Induction Induction learning involves an
    indirect approach to instruction, which
    emphasizes the role of DISCOVERY for
    learning.example.

50
Metalinguistic Strategies
  • Vocabulary Building
  • semantic priming
  • increased language base
  • auditory closure analogue
  • Construction of Meaning
  • situational cues At McDonalds, I grabbed a
    burger vs. The police officer grabbed a
    burglar
  • ambiguous sentences that change due to STRESS
    CUESexamples follow

51
Sentence meaning changes due to words emphasized
by increased loudness and prolonging duration
  • My MOM will pick me up in front of the school at
    330
  • My mom will pick me up IN FRONT of the school at
    330
  • My mom will pick me up in front of the SCHOOL at
    330
  • My mom will pick me up in front of the school at
    330

52
AUDIENCE PARTICIPATION TO IDENTIFY KEY WORD BASED
ON AUDITORY CUES
  • Tomorrow my brother will get an award at his cub
    scout meeting.
  • Today we need to go to the psychologist to get
    tests run.
  • On Tuesday, lets meet at P.F. Changs off exit 12.

53
Auditory Memory Enhancement
  • Teach strategies such as chunking or verbal
    rehearsal (e.g. Earobics 1 or 2 for word
    (Sam)/phoneme series (Noah) Karloons Balloons
    or Calling All Engines, I Spy programs for word
    lists/following directions when covering text on
    screen and modifying initially, Thinkin-Things I
    for auditory ONLY information)
  • Teach Imagery techniques draw key points to
    stories Post-It notes of correct of main
    points, then open set retell story based on
    pictures. Finally draw in your mind.

54
More memory enhancement activities to improve
visualization techniques
  • Use colorform-type pictures and stickers to
    increase memory for a list/series of items
  • Add one sticker
  • Next person, adds another sticker, and
    points/verbalizes the items in the order placed
    while LOOKING at the board
  • Next, that same person covers the board with a
    piece of construction paper (no visual cues) and
    repeats the sequence of the items placed, but
    pointing to the general location of where that
    item would be under the construction paper.
  • This continues for each persons turn until they
    are unable to name the list. It is not unusual
    for kids 10 years and up to be able to recall up
    to 16 items in a row, using this technique, and
    this give them a tremendous amount of confidence.
  • Discussing how we typically recall numbers of
    lists (chunking in 3 or 4, like phone numbers) is
    a good start to this activity.

55
Metacognitive Strategies
  • Assess childs metacognitive knowledge through
    their understanding of task demands
  • appropriate allocation of attention
  • identifying important parts of the message
  • self-monitoring
  • self-questioning
  • cognitive problem-solving
