The HED Task Catalog is under development. IDs are not stable until formal release. Comments are welcome at github.com/hed-standard/hed-task/issues.

Auditory and Pre-Attentive Deviance Processing

Scope: Pitch perception, auditory tone discrimination, acoustic processing, auditory perception; the family of processes indexed by MMN / oddball paradigms.

Note

Open issues: Tightly coupled to a specific measurement tradition (ERP). If the Catalog ever generalizes beyond MMN, the category boundary with Selective and Sustained Attention (feature-based attention) will need review.

This category contains 4 processes.

Acoustic processing

Process ID: hed_acoustic_processing

Low-level analysis of sound, including frequency, intensity, and temporal structure.

Tasks that engage this process: Mismatch Negativity Task

Fundamental references

  • Fletcher (1940) Reviews of Modern Physics 12:47–65 (DOI)

Auditory perception

Process ID: hed_auditory_perception

Perception of sound, including pitch, timbre, loudness, and spatial location.

Tasks that engage this process: Auditory Masking Task, Mismatch Negativity Task

Fundamental references

  • von Békésy (1960) Experiments in Hearing McGraw-Hill

Auditory tone discrimination

Process ID: hed_auditory_tone_discrimination

Also known as: tone discrimination

Judgment of whether two tones differ in pitch, intensity, or duration.

Tasks that engage this process: Mismatch Negativity Task

Pitch perception

Process ID: hed_pitch_perception

Also known as: pitch processing
