Understanding Auditory Processing Disorder (APD)
Auditory Processing Disorder (APD) is a hearing disorder that disrupts how the brain processes sounds, affecting a learner's ability to discern where a sound has come from, what it is, and when it happened. This can significantly impact language development and reading skills, even though learners with APD generally possess average to above-average intelligence.
APD occurs in approximately 5% of learners and is characterized by the central auditory pathways of the ear and brain not working in harmony to support sound understanding. This disorder often makes it challenging to comprehend speech in noisy environments and may co-occur with other diagnoses like dyslexia or reading development delays. Notably, APD is not typically associated with hearing loss and is generally assessed after the age of seven, although some early assessments can indicate if a learner is at risk.
APD and Learning
Learners with APD may experience:
- Poor attention and related behavioral issues
- Learning challenges
- Delayed phonological awareness and discrimination
- Reading development delays
- Difficulty with auditory memory, such as following multi-step instructions
These learners often respond well to adjustments and targeted interventions, which can include:
- Using listening devices and support for auditory learning
- Specific literacy interventions
- Interventions for understanding and learning speech and language
Explicit teaching of phonological awareness and phonics is crucial, as it forms the foundation of all literacy learning, especially reading.
Strengths of Learners with APD
Despite the challenges, learners with APD bring a wealth of strengths to the table, such as:
- Excellent visual learning skills
- Creativity
- Using visual strategies as part of their communication
Examples of Adjustments for APD
Environmental Adjustments
- Optimize classroom acoustics by managing distance and light to enhance visual cues.
- Seat learners closer to the front and slightly to the side to improve visibility of both the teacher and peers.
- Minimize visual distractions and provide a quiet area for work completion.
Teaching Adjustments
- Pre-teach vocabulary and use audiobooks to boost literacy and language development.
- Frequently check comprehension and provide learning materials in advance for pre-reading.
- Allow breaks from listening to prevent auditory fatigue.
Active Listening Adjustments
- Face the learner to improve visual access and ensure clear speech without obstructions.
- Reduce background noise and consider using a Soundfield system.
No two learners with APD are the same, and their experiences will vary based on their education, cultural, and family influences. Consequently, no single approach will meet the needs of all learners.
