An audiologist.

The nervous system processes information from the auditory system through the brainstem to the auditory cortex.

No, the input from the auditory system radiates out to other neural cortical regions for interpretation, combining, and storage.

Delays in responding, slow and deliberate speech, word-finding difficulties.

Coping with implied or expressed time pressures, appearing "a step behind," difficulty maintaining attention to tasks, exceeding time limits during tests, trouble with social pressures to perform "faster."

Age 7

There is an increase in inconsistency and variability in younger children, weaker reliability for test tasks, and developmental and maturational influences. Normative data availability for certain tests is limited for children under age 7.

Staggered Spondaic Word Test (SSW) by Katz (1962) and SCAN-3:C Tests for Auditory Processing Disorders in Children by Keith (2009).

Multidisciplinary testing involves assessments conducted by different professionals from various disciplines. It provides a more comprehensive understanding of the child's abilities and challenges, helping to identify evidence or indicators of CAPD.

It is essential to assess whether the child can actively participate in the evaluation tasks and tolerate the testing procedures. This ensures accurate and reliable results.

CAPD testing can provide additional information about the child's auditory processing abilities, which may guide interventions and treatment planning. If the results reveal specific deficits or challenges, interventions may be adjusted or added to address these areas.

CAPD testing may or may not be the starting point, depending on the child's individual situation and the information gathered from previous evaluations. It is important to consider the overall assessment results and the specific needs of the child when determining the appropriate starting point for assessment and intervention.

What evaluations have been completed so far to indicate evidence or indicators of CAPD?  Multidisciplinary testing prior to referral – why?

Can the child participate in the evaluation? Complete the tasks and/or tolerate the testing?

Would the results of the CAPD testing add information to the child’s profile and change the program being provided?

Interventions different? Added? Are the areas already being addressed?

CAPD testing: starting point or not? 

•have cognitive abilities to enable testing,

•have English as their primary language (or use assessments in the child’s primary language if other than English)

•have peripheral hearing within the normal range, and

•have intelligible speech.

Children need to have cognitive abilities that enable them to participate in the testing process effectively.

Children should have English as their primary language, or if they speak a language other than English, assessments should be conducted in their primary language.

Children should have peripheral hearing within the normal range.

Children should have intelligible speech.

CAPD primarily affects auditory processing abilities.

Acoustic, phonemic, and linguistic roles must be acknowledged from both a neurologically and behavioral standpoint when differentiating auditory processing from language processing.

Audiologists primarily view auditory processing from a neuropsychological perspective when differentiating it from language processing.

Speech pathologists primarily view auditory processing from a behavioral perspective when differentiating it from language processing.

The first 100-250 msec of an auditory stimulus presentation is considered the most critical for stimulus recognition in auditory processing.

Language processing starts at a very functional, concrete level during the acquisition of basic labels for aspects of our language.

Language processing requires the individual to pay attention to inflection, prosody, and tone in order to determine speaker intent.

Language is oral or spoken.

Literacy primarily pertains to reading and writing.

Phonological awareness serves as a bridge between language and literacy, with a focus on teaching graphic symbols to represent sounds.

code related skills that are prerequisite to developing reading and writing, or literacy.

Auditory processing skills, including phonological awareness, are prerequisite to language processing.

An acoustic stimulus must first be perceived as having a linguistic component before meaning can be extracted.

Sound discrimination and segmentation skills, involving the auditory analysis of acoustic stimuli, are considered critical foundation skills for both language and literacy.

Acoustic processing refers to the reception and transmission of the acoustic signal.

The primary focus of discrimination in auditory processing is distinguishing between linguistically encoded input and environmental input.

An audiologist examines the peripheral system, Central Auditory Nervous System (CANS), and the temporal lobe, from the 8th nerve to Heschl's gyrus, to assess the integrity of the auditory system.

Phonemic processing involves recognizing and knowing the code of spoken language, discriminating and analyzing the component parts of the signals, and applying and understanding the recognized code.

The initial requirement for phonemic processing is recognizing and knowing the code of spoken language.

Once the code of spoken language is recognized, it can be applied or understood.

The diagnosis in language processing and auditory processing depends on the tasks administered, the clinician performing the tests, and the stimulus used in the tests.

No, there is no distinct separation between auditory processing and language processing of the same stimulus.

Multiple anatomical and neurological structures overlap and work in cooperation in both language processing and auditory processing.

Pitch discrimination is typically evaluated by an audiologist as part of a Central Auditory Processing (CAP) battery.

Speech-Language Pathologist (SLP) typically evaluates the ability to understand spoken words, including nuances such as sarcasm.

Richards and Goswami (2015) investigated the auditory processing abilities for discrimination of psychoacoustic tasks, such as amplitude rise time, frequency, duration, and intensity.

The participants in the study conducted by Richards and Goswami (2015) were between the ages of 8 and 12 years.

The SLI group scored significantly lower on sensitivity to rise time and sound frequency discrimination, along with linguistic stress tasks, when compared to the typically developing controls.

Richards and Goswami (2015) hypothesized that poor auditory skills in rise time and frequency may relate to difficulty in processing stress patterns of speech, having a negative impact on the development of language.

The stages or transitions in the Processing Continuum from auditory acoustic processing to spoken language processing are: Auditory Acoustic - Auditory-Language - Spoken Language.

Test results should be interpreted in the context of age appropriate normative data by comparing them to the average performance of individuals of the same age.

Management plans for individuals with neuro-audiological development should be based on the stage of neuro-audiological development.

Behaviors associated with CAPD in the pre-school age group include difficulty localizing sounds, difficulty with rhyming sounds, and possible language delays.

Difficulty hearing in background noise, difficulty following directions, and poor "listening" skills are general behaviors associated with CAPD.

Academic difficulties commonly observed in individuals with CAPD include low academic performance, poor phonemic awareness/phonological skills, and difficulty with note-taking.

Yes, all students demonstrate academic indicators associated with CAPD at one time or another.

When assessing for CAPD, it is important to look for patterns and consistent indicators in terms of academic difficulties.

Observable difficulties associated with CAPD in terms of academic development include difficulties with language, listening, and reading.

Reading Disorders are characterized by impairments in the development of word recognition and reading comprehension.

Individuals with Reading Disorders often make errors such as omissions, distortions, and substitutions of words during oral reading.

Writing Disorders are characterized by impairment in the ability to compose written text, including spelling errors, difficulties within sentences, and/or poor paragraph organization.

Phonological Awareness is associated with dyslexia, which involves difficulties in processing speech and non-speech sounds, such as frequency and dichotic digits.

They may perform better in math than in reading, indicating a discrepancy in their abilities between these two subjects.

They may have difficulty with tasks that require multi-modality input or output, meaning tasks that involve multiple senses or modes of communication.

They may struggle with poor sound-symbol association and sight-recognition skills, which can impact their reading, spelling, and writing abilities.

They may have difficulty with symbolic language, which can affect their comprehension and use of language. Additionally, they may struggle with syntactic, semantic, and pragmatic skills, impacting their peer communication and interaction.

Yes, individuals with auditory integration difficulties may exhibit poor music skills, as music often relies on auditory processing and integration abilities.

Poor prosodic skills, or the ability to perceive and produce intonation, stress, and rhythm in speech, may be observed in individuals with auditory integration difficul

Individuals with auditory integration difficulties may struggle with listening in background noise or when multiple speakers are present. They may have difficulty filtering out irrelevant sounds and focusing on the intended auditory information.

They may have difficulty completing assignments in a timely manner, as their processing of auditory information may be slower or less efficient. They may also struggle with getting started on longer, multi-step assignments, as organizing and sequencing information can be challenging.

Individuals with auditory temporal processing difficulties may have difficulty recognizing the cadence or flow of multiple acoustic cues in a stream of speech. They may struggle to perceive and attach meaning to timing cues in speech, leading to challenges in understanding pacing and segmentation.

Auditory temporal processing difficulties can result in a perception of speech as a "blur" without clear delineation of salient features. This can make it challenging for individuals to extract the intended message from the auditory input.

Auditory temporal processing difficulties can have adverse effects on various areas of functioning. These may include reading and spelling skills, listening in noise, following directions, note-taking, auditory attention skills, and processing speed.

Auditory temporal processing difficulties can make it challenging for individuals to sequence critical elements within a message. They may struggle with organizing and processing auditory information in a sequential manner, which can affect their overall comprehension and ability to follow complex instructions.

Individuals with auditory temporal processing difficulties may exhibit "flat" monotone reading, lacking the natural rhythm and intonation typically observed in fluent readers. Their reading may lack expressiveness and variability in pitch and tone.

Auditory temporal processing difficulties can make it challenging for individuals to perceive and interpret subtle variations in speech cues. As a result, they may struggle to understand and recognize the intended sarcasm in verbal communication. Additionally, difficulties in processing timing cues can affect their ability to distinguish between homonyms or heteronyms, leading to confusion in language comprehension.

Individuals with auditory temporal processing difficulties may have difficulty recognizing and utilizing non-verbal pragmatic language cues, such as facial expressions, body language, and gestures. They may struggle to accurately interpret and respond to these non-verbal cues, impacting their overall social communication skills.

Individuals with auditory temporal processing difficulties may experience challenges in music-based skills. They may have difficulty perceiving and reproducing rhythmic patterns, keeping pace with the tempo, or recognizing melodic contours in music. These difficulties can impact their overall musical abilities and enjoyment of music.

A common manifestation of auditory memory difficulties is a tendency to forget earlier presented items and to retain what was heard most recently. Individuals with auditory memory challenges may struggle to retain and recall information presented to them, particularly when there is a delay between the presentation and recall.

Individuals with auditory memory difficulties may have difficulty following and retaining conversations and instructions, especially when the information is novel or when competing stimuli are present. They may experience challenges in retaining the information long enough to process and act upon it, leading to difficulties in comprehension and recall.

Auditory memory difficulties can contribute to reading comprehension problems. Individuals may struggle to retain and recall the information they have read, leading to difficulties in understanding and analyzing written texts. Additionally, auditory memory challenges can also affect spelling, as individuals may have difficulty retaining the visual representation of words and their correct orthographic forms.

Individuals with auditory memory difficulties may have a limited capacity to hold information at one time. They may struggle with processing and retaining a large amount of auditory information simultaneously. This limited capacity can impact their ability to follow complex instructions, remember multi-step tasks, or process and retain lengthy verbal explanations.

Auditory memory difficulties can impact the retention and recall of visual orthographic representations of words. Individuals may have difficulty transferring and storing the visual information of words in memory, which can lead to spelling problems. Difficulties in retaining and integrating auditory and visual information can affect their ability to accurately remember and reproduce the correct spelling of words.

-Easily over-stimulated

-Sensitive to loud sounds

-Handwriting problems due to motor planning problems

-Easily distracted

-Spoken language is often “cluttered”

-Weak receptive language skills

-Difficulty making inferences

Difficulties with auditory attention can manifest in various ways. Individuals may have difficulty choosing what to attend to, meaning they struggle to correctly determine the target of their attention. They may also experience distractibility, finding it challenging to selectively attend to a specific target while ignoring irrelevant or competing stimuli. Poor listening skills can be a result of difficulties in allocating attentional resources effectively, leading to difficulties in processing and comprehending auditory information.

Individuals with auditory attention difficulties often struggle to hear in background noise. They may have difficulty blocking out competing stimuli while attending to a specific target, which can result in reduced speech perception and comprehension in noisy environments. Background noise can be particularly disruptive for individuals with auditory attention challenges, as it adds an additional layer of competing stimuli that makes it harder to focus on the desired auditory information.

Individuals with auditory attention difficulties may face challenges in following oral instructions. They may struggle to maintain focus and attention while someone is speaking, making it difficult to process and remember the instructions given. Additionally, limited attention span can be a characteristic of auditory attention difficulties, leading to difficulties in maintaining attention over time. This can impact tasks that require sustained attention, such as lengthy conversations, lectures, or completing assignments.

Auditory attention difficulties are related to difficulties in allocating and sustaining attentional resources effectively. Individuals with these difficulties may have trouble regulating their attention and filtering out distractions, leading to challenges in focusing on and processing specific auditory stimuli. The issue lies in the ability to direct and maintain attention to the intended auditory target while filtering out irrelevant or competing stimuli.

Auditory attention difficulties can have a significant impact on listening skills. Individuals may struggle to actively and effectively engage in listening tasks, leading to reduced comprehension and retention of auditory information. They may have difficulty sustaining attention to the speaker or the auditory task, which can result in missed details, incomplete understanding, and difficulty following and participating in conversations or classroom activities.

In the Bellis/Ferre Model, secondary subprofiles refer to specific patterns of performance on an auditory test battery that indicate the involvement of higher order cognitive processes and language processing in auditory processing difficulties. These subprofiles represent the interface between auditory processing and other cognitive realms, where top-down factors become contributory to the processing of auditory input.

Secondary subprofiles typically manifest as language disorders when individuals with auditory processing difficulties are tested by a speech-language pathologist (SLP). This means that the challenges in auditory processing extend beyond the basic auditory skills and involve language processing as well. These individuals may exhibit specific patterns of deficits in language skills, such as difficulties with vocabulary, grammar, syntax, or semantic processing. The language disorders observed in these individuals are closely linked to their underlying auditory processing difficulties.

The associative deficit is a secondary subprofile characterized by the inability to apply the rules of language to incoming acoustic information, particularly when it involves linguistically complex information. This subprofile is sometimes referred to as "receptive childhood aphasia," although this term is not commonly used anymore. It is associated with lesions in the auditory association cortical areas, which are responsible for higher-level processing of auditory information.

In individuals with the associative deficit, there are receptive language deficits observed, particularly in the areas of vocabulary, semantics, and syntax. They may struggle to understand and interpret linguistically complex information, such as complex sentences, abstract concepts, or figurative language. These individuals may have difficulty applying the rules of grammar and syntax to incoming auditory information, resulting in challenges in comprehension and interpretation of language.

The associative deficit is associated with lesions in the auditory association cortical areas.

The output-organizational deficit is a secondary subprofile characterized by an individual's inability to plan, sequence, and organize their responses to auditory information or instructions. It affects their ability to effectively process and produce output in response to auditory stimuli.

Individuals with the output-organizational deficit may experience various challenges, including difficulty hearing in noise, poor organizational skills, difficulty following directions, frequent reversals (such as letter or number reversals), and poor recall and word retrieval abilities. These difficulties can impact their ability to accurately and efficiently process and respond to auditory information.

Auditory fatigue refers to a state of tiredness or exhaustion that occurs as a result of prolonged or intense exposure to auditory stimuli. It can occur when the auditory system becomes overwhelmed or fatigued due to continuous or excessive processing of auditory information. Auditory fatigue can lead to a decrease in the individual's ability to accurately process and respond to sounds, resulting in difficulties with listening, comprehension, and attention.

Auditory overload occurs when the auditory system is overwhelmed by an excessive amount or intensity of auditory stimuli. It can occur in environments with high levels of noise or when multiple sounds or voices are present simultaneously. Auditory overload can negatively impact an individual's ability to focus on specific sounds, understand speech, or filter out irrelevant background noise. It can result in difficulties with attention, concentration, and overall auditory processing.

Recovery time refers to the amount of time it takes for the auditory system to recover or return to its baseline functioning after experiencing auditory fatigue or overload. It represents the period needed for the auditory system to rest and restore its processing capacity. Recovery time can vary among individuals and may depend on factors such as the intensity and duration of the auditory stimulation. Adequate recovery time is important to ensure optimal auditory processing and to prevent further difficulties or fatigue.

Auditory fatigue and overload can have various secondary behavioral implications. Individuals may experience increased levels of anxiety, frustration, or anger due to the challenges they face in processing auditory information and coping with overwhelming auditory stimuli.

Distractible, “Spaced Out”,

  Daydreaming, Off Task

Mislabeling refers to the incorrect or inaccurate identification or characterization of behaviors or symptoms as solely stemming from auditory processing difficulties. It occurs when behavioral problems or irresponsible behaviors are attributed solely to auditory processing challenges without considering other underlying factors or co-occurring conditions. Mislabeling can lead to a misunderstanding of the individual's needs and may result in inappropriate interventions or support.

Misdirected interventions in the context of auditory processing refer to the implementation of interventions or treatments that are not appropriate or effective for addressing auditory processing difficulties. This can occur when interventions focus primarily on behavior modification techniques that do not directly target the underlying auditory processing deficits. It can also involve the inappropriate use of pharmacological interventions, such as psychotropic medications, without considering the specific needs and nature of auditory processing challenges. It is important to ensure that interventions are tailored to the individual's specific auditory processing needs and address the core deficits to promote optimal outcomes.

The goal of auditory training is to re-wire, re-organize, and potentially activate neurons and neural connections that were previously in a state of rest.

The three types of auditory training based on neural plasticity are: developmental, compensatory, and learning-related.

The educational goal of auditory training is to improve listening skills, comprehension, spoken language processing, and overall educational achievement.

Auditory training is conducted using an acoustically controlled approach. It follows an intensive schedule and targets specific stimuli to maximize effectiveness.

The goal of auditory intervention for auditory discrimination is to improve the listener's ability to discriminate, identify, and recognize fine and/or rapidly changing acoustic cues. This process is critical for discriminating acoustic stimuli, such as speech segments and phonemes.

Auditory discrimination is considered one of the most basic fundamental auditory processes because it involves the ability to perceive and differentiate different sounds or stimuli. It forms the foundation for higher-level auditory skills and is essential for speech and language development.

The goal of auditory intervention for auditory closure is to improve vocabulary building and the listener's ability to comprehend and understand words, especially when confronted with unfamiliar or misperceived words. Pre-teaching or introducing new words can be part of the intervention strategy.

Auditory intervention for auditory closure supports vocabulary building by providing opportunities to expand the listener's vocabulary base. This intervention approach focuses on introducing and reinforcing new words, helping the individual understand and comprehend words in different contexts, and improving their overall language skills.

Some auditory intervention activities for improving temporal processing skills include sound pattern training, where individuals identify and mimic patterns with differing durations and frequencies. Prosody training is another activity that focuses on paying attention to stress and prosody while reading or listening to poetry. Duration discrimination training helps individuals differentiate the timing between word boundaries. Sequencing tasks and heteronym differentiation, such as understanding the different meanings of words that sound alike but have different spellings, also target temporal processing skills. Additionally, activities like identifying word boundaries via temporal cueing, reading poetry, and following auditory directives can help improve temporal processing skills.

The purpose of sound pattern training in auditory intervention for temporal processing skills is to enhance the individual's ability to identify and mimic patterns with differing durations and frequencies. By engaging in this training, individuals develop their auditory perception and discrimination skills, allowing them to better recognize and process temporal cues in speech and other auditory stimuli.

Prosody training focuses on attention to stress and prosody while reading or listening to poetry. By paying attention to the rhythmic and melodic aspects of speech, individuals can improve their temporal processing skills. Prosody training helps individuals develop a better understanding of the timing, emphasis, and intonation patterns in spoken language, which can contribute to improved comprehension and communication skills.

Duration discrimination training is important for temporal processing skills as it helps individuals develop their ability to perceive and differentiate the timing between word boundaries.

Activities like heteronym differentiation, which involves understanding the different meanings of words that sound alike but have different spellings, and following auditory directives, where individuals listen and respond to specific instructions, support temporal processing skills by requiring accurate interpretation and sequencing of auditory information. These activities help individuals develop their ability to process and organize auditory stimuli in a timely and accurate manner, enhancing their overall temporal processing skills.

Some auditory intervention activities for improving binaural separation skills include speech recognition in noise tasks, where individuals practice understanding speech in the presence of competing background noise. Intensity altered dichotic listening is another activity where individuals listen to auditory stimuli with different intensity levels in each ear, challenging their ability to separate and attend to specific auditory information. Listening to stereo music with intensity imbalances can also help improve binaural separation skills. Additionally, auditory vigilance training, which involves maintaining attention and responding to specific auditory stimuli, can contribute to the development of binaural separation abilities.

Binaural integration/summation activities in auditory intervention aim to enhance the individual's ability to synthesize acoustic information from both ears

DIID training, which involves directing auditory stimuli to the stronger ear at a reduced level, aims to improve the processing and integration of auditory information across the two hemispheres, particularly involving the corpus callosum. By practicing tasks that require attending to specific auditory cues presented to the stronger ear, individuals can strengthen their ability to integrate and process auditory information effectively, leading to improved auditory processing skills.

Ear plugs can be used in auditory intervention to reduce the amount of auditory input and simulate a more challenging listening environment. By wearing ear plugs, individuals can experience reduced auditory input and practice focusing on specific auditory cues or instructions. This can help enhance their ability to filter out background noise and attend to relevant auditory information, leading to improved auditory processing and attention skills. However, the use of ear plugs should be carefully monitored and adjusted based on individual needs and recommendations from professionals.

Auditory vigilance can be improved in auditory intervention through various strategies. One approach is to increase and improve awareness of acoustic stimuli by engaging in activities that require sustained attention to auditory cues. This can involve tasks with multi-step or complex auditory directives, where the listener needs to listen carefully and follow instructions accurately. Another approach is to work on listening to instructions fully before performing a task, encouraging the individual to pay close attention to the auditory information provided. Additionally, providing target words, sounds, categories, or ideas randomly scattered throughout increasingly longer passages read aloud can help improve auditory vigilance by challenging the listener to actively listen and identify the specific targets within the auditory stimuli.

Auditory memory enhancement (AME) can be achieved through various strategies in auditory intervention. One approach is through the use of sketching, where individuals can create visual representations of auditory information to aid in the recall and retention of concepts. Rehearsal strategies, such as repeating or rephrasing auditory information, can also help improve auditory memory. Additionally, using imagery and tag words to emphasize language and transitions can enhance the encoding and retrieval of auditory information. By focusing on understanding general concepts rather than trying to recall larger amounts of detail all at once, individuals can develop their ability to listen, process, and recall auditory information more effectively.

The type of noise, the loudness of the noise relative to the target sound, and the task demands.

Improving the signal-to-noise ratio is a primary consideration for enhancing decoding skills in the classroom.

Individuals with integration and prosodic difficulties can be bothered by noise, especially in tasks that have increased multisensory demands. In such cases, altering task demands, removing noise from the environment, taking frequent breaks, extending test or project completion time, and reducing assignment size can be helpful.

To address the impact of random noise on individuals with integration and prosodic difficulties, task demands can be altered. This can involve removing the noise from the environment, allowing for frequent breaks, extending the time allotted for tests or projects, and reducing the size of assignments.

To address difficulties with organization in relation to classroom acoustics, it is important to reduce chaotic or over-stimulating environments. This can help individuals who have trouble filtering out distractions, both visual and auditory. Additionally, noise desensitization activities can be beneficial in improving tolerance and filtering of noise.

For individuals with associative difficulties, background noise may not necessarily be the primary factor. Instead, it is often the linguistic clarity of the signal that affects their performance. It is important to focus on improving the linguistic clarity of the signal rather than just the acoustic clarity in order to support their language processing skills.

•Provide structure and demonstrate an organized work area

•Reduce visual distractions in the classrooms

•Seat the student close to the teacher

•Strategic seating with flexibility

•Seat away from windows or doorways

•Provide an unobstructed view of the chalkboard, teacher, movie/TV screen

•Keep extra supplies of classroom materials on hand

•Maintain adequate space between desks

FM/DM Listening Systems are used to enhance classroom acoustics for students with auditory challenges. These systems provide a direct audio feed from the teacher to the student, reducing the effects of background noise and distance.

Personal FM/DM systems are designed for individual students and provide a direct audio feed to their hearing aids or headphones. CADS, or Classroom Amplification Distribution Systems, are designed for group listening and distribute the teacher's voice evenly throughout the classroom using speakers or sound field systems.

Carpeting, curtains, and drapes help absorb sound and reduce reverberation in the classroom. They can dampen sound reflections and reduce background noise, creating a quieter learning environment.

Some other modifications that can improve classroom acoustics include installing acoustic ceiling tiles, using baffles within the listening space, eliminating open classrooms, and damping highly reflective surfaces. These modifications help reduce sound reflections and create a more acoustically favorable environment for students.
