APD Evaluations at Auditory Processing Center Typically Involve Each of the Following Areas:

Auditory Processes

  • Binaural Integration – The ability to understand different messages presented to each ear simultaneously
  • Binaural Separation – The ability to selectively attend to and understand a message presented to one ear while ignoring a message presented to the opposite ear at the same time
  • Binaural Interaction/Fusion – The ability to utilize localization and subtle intensity and timing differences in signals arriving to each ear. This affects the ability to detect signals in noise from both ears working together at the level of the brainstem. For example, the listener may be asked to identify a word as it emerges from competing background noise or fuse different inputs together into one perception
  • Temporal Processing – This includes Temporal (timing) Aspects of Auditory Processing: such as the ability to detect the brief time interval between sequential speech sounds, integrate sequences of sounds into words, and recognize individual speech sounds when they quickly follow one another and Auditory Pattern Recognition: referring to the ability to determine similarities and differences in acoustic contours and sequence and label patterns of sounds. This yields useful information about the efficiency of interhemispheric transfer of auditory information.
  • Auditory Closure – The ability to to fill in and recognize an auditory signal when some of the information is distorted or missing and recognize the whole message. This includes filtered speech (high pitched sounds have been deliberately removed causing the words to sound muffled) and time altered speech (presented at very rapid rate making it difficult to hear the rapid transitions between individual speech sounds).
  • Auditory Figure-Ground – The ability to understand auditory messages in the presence of background noise or competing speech
  • Spatial Processing – The functioning of the mechanisms that use the spatial distribution of sound sources to suppress unwanted sound. This ability allows us to focus on one sound while ignoring sounds coming from other directions.

Functional Auditory Processing Skills

  • Auditory Attention – The ability to determine the target and selectively attend to auditory information for an appropriate length of time
  • Auditory Discrimination – The ability to distinguish between sounds to accurately identify sounds or words presented orally (such as /b/ and /d/ or the words “ball” vs. “doll.”)
  • Auditory Short Term Memory involves retaining what was just heard to immediately recall details. Auditory Sequential Memory  is the ability to recall sequential auditory stimuli in the exact order they were presented. Auditory Working Memory  involves the ability to recall, manipulate,  and use auditory information just presented.
  • Phonological Awareness – The explicit knowledge of the sound segments (phonemes) that comprise words and sound/symbol (phoneme/grapheme) correspondence. Skills typically evaluated include: Sound Analysis – the ability to correctly discern the component sounds of words;  Sound Blending/Phonemic Synthesis – the ability to combine sounds accurately to blend them into syllables and words; and Sound Segmenting – the ability to hear and separate the individual sounds that have been combined to create syllables and words.
  • Higher Level Language ProcessingAuditory Comprehension – answering questions about what was heard, and Auditory Reasoning – answering questions involving higher order linguistic processing related to abstract concepts, making

    inferences, and coming to logical conclusions about what was heard.
