Continuum of Processing
Acoustic Processing Linguistic Processing & Executive Functions
Transition AreaPhonemic/Phonetic Processing
Neuroscientific Bases of CAP
• perceptual processing of auditory stimuli, and neurobiological activity underlying that processing (ASHA, 2006)
• disorders of CAP cannot be attributed to higher‐order language, cognitive, or related confounds
• CAPDs may lead to/be associated with difficulties in higher‐order language, learning, and communication function
Differential diagnosis
• Differentiates among disorders having similar symptoms/ manifestations
• SLP’s, psychologists, neuropsychologists & others provide insights into auditory performance in various contexts
• Audiologists use well‐controlled, norm‐referenced tests that minimize influence of language, cognition & other sensory skills & maximize auditory system function
• Tests designed to tax CAP skills
• Patterns across tasks are used to diagnose specific CAPD
• Test results help professionals customize deficit‐specific differential intervention
• Differential Intervention:
– A balance of treatment and management based upon neuroscientific principles and derived from assessment results
– Customizes treatment and management plans in order to treat directly impaired skills and to minimize impact on listener’s life
Neuroscience foundations

The “geography” of processing
• Peripheral auditory system
– Collect the sound
– Detect the sound
– Transform into a neural signal
• Brainstem processing
– Localization
– Selective/divided attention
– Preliminary acoustic feature extraction
The “geography” of processing
• Cortical AUDITORY processing
– Analyze/discriminate
– Synthesize/Integrate
• Cortical PHONOLOGIC‐LINGUISTIC processing
– Attach meaning
• Cortical EXECUTIVE processing
– Execute a response
Adequate Processing Involves Continuum of Skills
• Intact peripheral auditory system – receive acoustic stimulus
• Intact CANS – transmit through brainstem to upper cortex (Heschl’s gyrus)
• Phonemic knowledge to discriminate aspects of the acoustic stimulus
• Linguistic knowledge to decode message
• Executive function skills to attend, organize, execute behavioral response
Anatomic Structure/Site
Type of Processing
Peripheral Auditory System
External, Middle, Inner Ear, auditory nerve

Basic Principles
• Audiologists uniquely suited to diagnose CAPD
• SLP’s , psychologists, neuropsychologists & others provide insights into listener’s auditory performance in various contexts
• Results provide insights into listener’s strengths & weaknesses in academics, communication, and life skills
CAPD Assessment
• Screening determines those listeners at‐risk for CAPD
• Can screen by test, checklist, or record review
• NO standard screening protocol currently available
• Diagnostic testing determines presence/absence of disorder and specifies nature
• Audiologists diagnose CAPD
• Test battery recommended
CAPD Assessment• Screening by checklist
– CHAPS, SIFTER, LIFE, others
– not standardized or validated
– subjective
• Screening by record review
– look at academics and other test results
– not standardized or validated
• Screening by test
– SCAN‐C, SCAN‐A, SCAN‐3, ACPT
– DSTP – Differential Screening Test for Processing
CAPD Test Battery• What?
– Battery of tests to determine how efficiently CANS operates
• How?– Overloading or overworking it
– Minimize influence of language, cognition & other sensory skills on performance
– Maximize function of CANS
• Who?– Diagnostic tests available for children as young as 6 yrs
– Results compared to age‐matched peers– Look at processes taxed and underlying anatomical site
Performance profiles yield insights into nature of CAPD

Interpreting Diagnostic Results
• Remember your goal – evaluating integrity of auditory skills/systems, NOT just dxing CAPD
• Look at individual tests – absolute, norm‐referenced
• Look at the battery – relative, patterns
• Look at the “big picture” – impact of deficit on communication, academics, sense of self
6
• Absolute analysis
– Norm‐referenced
– Compare to age‐matched peers
– Per test pass‐fail criterion: >2SDs below mean for age
• Relative analysis
– Examination of patterns across tests
• Ear differences
• “Ties that bind”
• Abnormal AND normal scores
• DON’T “diagnose” per test – use entire battery!
Interpreting CAP test results Test Interpretation
• NOT CAPD
– Performance below normal on single test
– Performance below normal on all tests
• Evidence of CAPD
– Poor scores on sets of tests tapping similar function
– Bellis/Ferre model describes 5 test profiles
– You are NOT obligated to use a specific model
Ask yourself…
• How did listener perform on degraded speech tests?
• How did listener perform on binaural processing tests?
• How did listener perform on temporal processing tests?
• Behaviors while testing?
Questions that you ask yourself
• What is status of conductive mechanism?
• Status of cochlear/retrocochlear mechanism?
• Evidence of deficient auditory discrimination? – how do you know?
• Evidence of impaired binaural processing?
– What is it? What type of bin proc issue?
• Evidence of impaired temporal processing?
– what is it? What type of problem?
• Other issues?
• Does it make sense? What does it mean?

Summary• Use battery of CAP‐specific tests
• No one test taps into only one skill
• Base diagnosis on BATTERY. Don’t “diagnose” per test
• Look for the “tie that binds”
• Don’t ignore contradictory findings
• Does diagnosis “make sense” based on neuroscience
• Neither Dx nor Tx for CAPDs can be done using a “cookbook” approach

Management Remediation
Modification of the communicative environment
Use of compensatory strategies
Minimizes adverse effect of disorder of client’s life
Formal and informal therapy to develop deficient
skills AND
Teach compensatory strategies
Designed to reduce or resolve deficit

When choosing management strategies and/or remediation programs:
• Focus on the listener (remediation)

• Focus on the message (accommodations & strategies)
Focus on the listener: remediation
• Based on neural plasticity research
– Plasticity is brain’s ability to organize/reorganize in response to stimulation

• CCSS.ELA‐literacy.CCRA.SL.1
– Prepare for and participate effectively in a range of conversations and collaborations with diverse partners, building on others’ ideas and expressing their own clearly and persuasively
• CCSS.ELA‐literacy.CCRA.SL.2
– Integrate and evaluate information presented in diverse media and formats, including visually, quantitatively, and orally.
• CCSS.ELA‐literacy.CCRA.SL.3

Listener: Remediation for CAPDs
• When choosing treatment program, consider
– Reported efficacy of program for specific populations – Does it work?
– Program’s neuroscientific foundations – Should it work?
– Appropriateness for type of deficit identified – Does it fit?

For all students
• Student will demonstrate ability to use active listening strategies
– Active listening ‐ taking responsibility for one’s listening success or failure by understanding impact of auditory impairment in one’s life, recognizing aspects of communication under listener’s control, displaying effortful listening behaviors, taking overt steps to avoid or correct potential communication mishaps.
• Student will maintain auditory vigilance for “X” amount of time
Active listening• Student will state two difficult listening situations that he/she has encountered
• For a self‐reported difficult listening situation, student will state (and practice) one strategy to minimize the listening difficulty
• Student will follow conditional directions, requesting clarification as needed
15
Auditory vigilance
• Given a string of random words (or phonemes), student will indicate through hand signal each occurrence of pre‐determined “target” word
• Student will indicate through hand signal “rare” or different target from within a string of common targets (e.g., buh‐buh‐dee‐buh‐buh‐buh‐buh‐dee)
