- Phonetic Coding (PC). Ability to hear phonemes distinctly. This ability is also referred to as phonological processing and phonological awareness. People with poor phonetic coding have difficulty hearing the internal structure of sound in words.
- Speech Sound Discrimination (US): Ability to detect and discriminate differences in speech sounds (other than phonemes) under conditions of little or no distraction or distortion. Poor speech sound discrimination can produce difficulty in the ability to distinguish variations in tone, timbre, and pitch in speech.
- Resistance to Auditory Stimulus Distortion (UR). Ability to hear words correctly even under conditions of distortion or loud background noise.
- Memory for Sound Patterns (UM). Ability to retain (on a short-term basis) auditory events such as tones, tonal patterns, and voices.
- Maintaining and Judging Rhythm (U8). Ability to recognize and maintain a musical beat. This may be an aspect of Memory for Sound Patterns as short-term memory is clearly involved. However, it is likely that there is something distinct about rhythm that warrants a distinction.
- Musical Discrimination and Judgment (U1 U9). Ability to discriminate and judge tonal patterns in music with respect to melodic, harmonic, and expressive aspects (phrasing, tempo, harmonic complexity, intensity variations).
- Absolute Pitch (UP). Ability to perfectly identify the pitch of tones. As a historical tidbit, John Carroll had perfect pitch.
- Sound Localization (UL). Ability to localize heard sounds in space.
