Description

Auditory processing is what the brain does with sound once it has been heard: locating sounds, telling them apart and interpreting them as meaningful, so that a listener can attend to, understand and remember speech and control their own speaking. It underpins spoken language and listening comprehension and lays the foundation for reading and writing, including phonological awareness, at every age the LVN covers from pre-kindergarten to adulthood. It is still developing through adolescence, when academic demands on listening rise. Difficulties show up most where speech must be followed against background noise, as in a busy classroom, and learners with dyslexia may process speech sounds differently. It is measured with standardised batteries of auditory attention, auditory memory and phonological skills, and with tests of auditory processing speed. It is distinct from hearing itself, which access covers, though hearing loss affects it; in older adults, age-related decline in hearing speech in noise is part of the picture.

Implications

Context

• Classroom noise makes listening harder; quieter rooms, seating near the speaker and written or visual back-up help.
• Instruction delivered mainly by speech puts learners with auditory processing difficulties at a disadvantage.
• Learners of a new language may struggle to hear sound contrasts that their first language lacks.

Target Learners

• Young children building speech, phonological awareness and early reading.
• Learners with dyslexia, hearing loss or auditory processing difficulties; older adults.
• Multilingual learners.

Target Learning Objectives

• Listening comprehension and spoken communication.
• Phonological awareness, word recognition and reading comprehension.

Claims

• All participants believed heritage learners perform better in classroom listening, but dialectal differences posed difficulties for HLLs that NHLLs did not notice [~W] — learners who differ on it differ in outcomes
• Heritage and non-heritage learners perceive textbook listening activities in reversed ways: no HLL found them difficult and no NHLL found them easy [+W] — learners who differ on it differ in outcomes
• Meaningful background speech impairs delayed memory for texts in teenagers more consistently than transportation noise [~M] — learners who differ on it differ in outcomes
• No individual alphabetics outcome reached statistical significance in the WWC analysis [-M] — instruction changes it
• Noise impairs children's performance in complex listening tasks beyond simple identification, with children affected more than adults [+M] — learners who differ on it differ in outcomes
• One-year follow-up and LiPS-vs-RWT supplemental comparisons showed mostly non-significant differences, with some follow-up alphabetics effects remaining significant [~W] — instruction changes it
• Read, Write & Type!™ shows statistically significant positive effects on phoneme segmenting and word attack relative to regular classroom instruction for low-achieving first graders [+W] — instruction changes it
• Activation in frontal and parietal cognitive regions is positively correlated with speech-in-noise behavioral performance in older listeners, supporting a compensatory role [+M] — learners who differ on it differ in outcomes
• Group x condition interactions show condition-dependent activation differences in superior temporal, parietal, cingulate, medial frontal, and middle temporal regions [~M] — learners who differ on it differ in outcomes
• In an auditory number-cue detection task, both blind and sighted adults detect targets faster on number-size/location congruent trials, with no group difference [-M] — learners who differ on it differ in outcomes
• Middle temporal gyrus activation in older listeners correlates with performance only in non-debilitating listening conditions, not in severe noise [~M] — learners who differ on it differ in outcomes
• Older adults show a more diffused cortical network involving frontal and ventral regions, whereas younger adults show a streamlined auditory network during speech-in-noise processing [+M] — learners who differ on it differ in outcomes
• Older adults show reduced accuracy in severe noise (SNR -5) but perform comparably to younger adults in quiet and moderate noise (SNR 20) [~M] — learners who differ on it differ in outcomes
• Older adults show reduced activation in auditory cortex and increased activation in prefrontal and precuneus regions during speech-in-noise processing [+M] — learners who differ on it differ in outcomes
• The effect of selective auditory attention on early neural processing differs between children of higher and lower maternal education (significant group × attention interaction within 100–200 msec) [~M] — learners who differ on it differ in outcomes
• The maternal-education group difference in neural attentional modulation persists after controlling for receptive language scores [+M] — learners who differ on it differ in outcomes
• Longer target P3 latencies are associated with poorer sustained attention in toddlers [+M] — learners who differ on it differ in outcomes
• Children with specific language impairment show reduced selective attention to and integration of audiovisual speech [+M] — learners who differ on it differ in outcomes
• Individuals with dyslexia show impairments in audiovisual integration beyond phoneme-grapheme mapping [+M] — learners who differ on it differ in outcomes
• Multisensory temporal precision in autism is linked to speech integration, language abilities, and clinical symptomatology [+W] — learners who differ on it differ in outcomes
• Older adults show larger multisensory gains for simple stimuli but multisensory deficits for complex speech stimuli [~M] — learners who differ on it differ in outcomes
• Culturally familiar emblematic gestures improve L2 speech perception and social evaluations, whereas unfamiliar emblems reduce them [+M] — instruction changes it
• In a double mediation path model, RCR is associated with listening comprehension, which is associated with vocabulary, with the direct vocabulary-to-RCR effect fully mediated [+W] — learners who differ on it differ in outcomes
• RCR is correlated with vocabulary and listening comprehension in the combined sample [+M] — learners who differ on it differ in outcomes
• Apparent improvements from systematic sensory training locate in central factors such as attention and understanding, so strictly there is no sense training [-W] — instruction changes it

Measures

• Test of Auditory Processing Skills (Martin, Brownell & Hamaguchi, 2018): auditory attention, auditory memory and phonological skills for ages 4 to 18.
• Auditory Processing Speed Test (APS-T) (Cameron et al., 2014): speed of processing spoken language for ages 6 to 12.

Related Learner Variables

• Access: hearing loss diminishes auditory processing, while congenital blindness can sharpen it.
• Attention: attending to speech in noise depends on auditory processing.
• English-Learner Status: non-native sound contrasts are hard to hear, though bilingualism can help with filtering noise.
• Sensory Integration: auditory processing difficulties may contribute to sensory integration difficulties.
• Communication Skills: auditory processing difficulties go with communication and listening difficulties.
• Working Memory: holding and manipulating heard information depends on auditory processing.
• Academic and Critical Literacy: learners with auditory processing difficulties may need added support with reading and language.
• Executive Function: managing several languages may shape how inhibition operates on what is heard.
• Prior Knowledge: heard information has to be processed before it can become background knowledge.
• Adverse Experiences: maltreatment is associated with more auditory processing difficulties.
• Phonological Awareness: speech perception underlies phonological awareness and processing.
• Decoding: auditory processing difficulties often come with weaker word recognition.
