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.

Language Comprehension and Production

Scope: Mapping sound or text to meaning and meaning to articulation: lexical access, word recognition, reading, phonological processes, syntactic parsing, sentence comprehension, discourse processing, semantic processing, semantic knowledge, naming, verbal fluency, speech perception, speech production, language comprehension, language production.

Out of scope: “Language” as a faculty; linguistic representations themselves; motor aspects of articulation (those live in Motor Preparation, Timing, and Execution as vocal-motor control, with a pointer from here).

Note

Open issues: Reading as a process versus reading as a behavior is still somewhat conflated in hed_reading - an open question.

This category contains 16 processes.
