Definition, Theory, Evaluation, Treatment

OROR

It don’t mean a thing if it ain’t got that swing

Or worse in some ways it means the wrong thing

CHALLENGESCHALLENGES

Realizing this outline is a difficult talkBecause prosody and its disorder-

aprosodia-are difficult to define, describe, evaluate (reliably) and treat (effectively)

NONETHELESSNONETHELESS

Certain general notions are robust enough for us to make a beginning

Common to think of linguistic prosodyAnd emotional prosody

BUT FIRSTBUT FIRST

what is prosody?– The suprasegmental features (segments are

sounds) of speech conveyed perceptually by pitch stress and duration

– And acoustically as changes in frequency, intensity and timing

VALUE OF ACOUSTICVALUE OF ACOUSTIC

Aids in quantification of perceptual judgement

Especially critical in area such as aprosodia where diagnosis is so difficult

WAY TO THINK ABOUT WAY TO THINK ABOUT DIFFICULTYDIFFICULTY

Segmentals are the prosesuprasegmentals are the poetry

CONSIDERCONSIDER

– A Thought Revolved by Wallace Stevens

DIFFERENCESDIFFERENCES

Meaning is less transparent in one than the other

This captures the huge difficulty of assessing, diagnosing and treating aprosodia

But progress has been madeAgreed upon types

LINGUISTICLINGUISTIC

Disambiguates words (black bird and blackbird) and

Sentences (He wrote poetry. He wrote poetry?)

Also called intrinsic prosody Thought to be primarily the product of left

hemisphere mechanisms

AFFECTIVEAFFECTIVE

Conveys a speaker’s emotions and attitudesI missed spending time with my father in

law uttered with joy or great sorrowSometimes called extrinsic prosodyThought to be primarily the product of right

hemisphere mechanismsDepends heavily on changes in fundamental

frequency

APROSODIAAPROSODIA

Our emphasisRoss in 1981 referred to deficits in

expression and reception of affective or emotional prosody as the aprosodias

He said “their functional-anatomic organization in the right hemisphere (mirrors) that of propositional language in the left..) P. 561

THEREFORETHEREFORE

He identified a motor aprosodia in which reception of emotional prosody was intact

A receptive in which reception was inordinately impaired

And counter parts of global, transcortical motor, transcortical sensory and so on

VALIDITYVALIDITY

These are notions in search of dataNonetheless clinicians know right

hemisphere damage (especially) can effect the processing of emotional prosody

Ross describes divorce as a consequence of a patient’s not being able to express emotion

Clinicians have other similar tales

HOWEVERHOWEVER

Until our recent work no therapiesIn general clinicians were likely to throw up

their hands when confronted with the multiple problems of right hemisphere damage

THE PROBLEMSTHE PROBLEMS

Limited measurement tools or testsNon-data based cutoffs of normal and

abnormal for those that do existVariability in the emotional prosody of the

populationThe thorny problem of laboratory versus

true emotional prosody

DESPITE ALL THISDESPITE ALL THIS

Theories have begun to emergeEvaluation procedures likewiseTreatment techniques have begun to appearWith the deepest roots right here at the

University of FloridaNourished by our own Ken Heilman

THEORIESTHEORIES

Against the background that Myers (1999) establishes with her comment that “Mechanisms of RHD prosodic deficits are not presently understood”

Heilman and his colleagues have proposed some– One is a motor theory– In simplest form the notion is that (especially

expressive aprosodia) results from a deficit of execution or of programming

`THE SECOND`THE SECOND

Degredation of a modality specific affect lexicon

Clearly this is the right hemisphere equivalent of the verbal lexicon in the left hemisphere

NADEAU EXPANSIONNADEAU EXPANSION

The affective lexicon “may be instantiated in a pattern associator network linking predominately right hemisphere association cortices and limbic structures and limbic structures with right prefrontal and and premotor cortex”

EXCLUDED EXPLANATIONSEXCLUDED EXPLANATIONS

DepressionAgnosognosiaNeglectDysarthria

EVALUATIONEVALUATION

Here is where challenge of poetry is most acute

Judgment of presence of both expressive and receptive aprosodia is subjective

Tools have been developed to standardize the stimuli

Response evaluation is still subjective

THE FABTHE FAB

Bowers, Blonder, Heilman, 1998Assesses ability to identify spoken prosodyAnd facial expressionAnd interesting notion is the relationship of

facial and spoken expression

THE FEEBTHE FEEB

Not yet non-standardizedAssesses spontaneous and and imitative

prosody, both affective and linguisiticEvaluation is perceptualMeaning judges say aprosodic or not.

COMING TOGETHERCOMING TOGETHER

The theories, primarily, generated two treatments One called Imitative The other called cognitive-linguistic Both comprised six steps Both are loosely based on notions of errorless

learning In that they go from maximum to minimum cueing Both motivated by theories of pathophysiology

IMITATIVE TREATMENTIMITATIVE TREATMENT

Step One: Cl models the requested emotional utterance and then cl and pt say together

Step Two: cl models and the pt produces after delay

finally, Produce the sentence in target tone of voice while imagining speaking to a family member

COGNITIVE-LINGUISTICCOGNITIVE-LINGUISTIC

Step One: Pt given a written description of characteristics of a given tone of voice

Step Two: Pt given cards listing names of emotions and asked to pick which emotion matches the tone of voice just described

Advances to Step six in which pt is asked to produce tone of voice based on all written cues previously provided

RESEARCHRESEARCH

Heilman and colleagues won a program project grant from NIH

THE DESIGNTHE DESIGN

Heilman and colleagues chose the replication of an ABAC design

A equals baselineB equals one of the two treatments chosen

randomlyThe second A is baseline after one month

“wash out” periodC is the second treatment

DETAILSDETAILS

Stable baseline confirmed with C statistic 20 sessions of the first treatment selected

randomly Post test One month “washout” Pretest 20 sessions of treatment two Post test immediately and at one and three months

DEPENDENT MEASUREDEPENDENT MEASURE

Participants were shown a card with a sentence and asked to utter the senteNce in a particular tone of voice

Adequacy of emotion judged by naïve person

Knew nothing of stage or treatment

EMOTIONSEMOTIONS

Treated– Sad– Happy– Angry

Control– Fearful

Statistical Analysis Visual Analysis

CONCLUSIONSCONCLUSIONS• The treatments seem to have an effect

•Analysis underway to determine if one more influential than the other

•And to determine responders and non- responders

•Submitted another grant and got butchered

•So more work to do

BUTBUT

• Hope is the thing with feathers

• That perches in the soul

• And sings the tune without the words

• And never stops at all
