this disorder is a sensory processing issue
- sound localization and lateralization - auditory discrimination -auditory pattern recognition Difficulty interpretting auditory information when presented in less than optimal listening environment usually have good hearing acuity - not easily recognized by professionals -difficult to differentiate from LD, ADD, ADHD |
