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.

Cognitive processes

The Catalog defines 172 cognitive processes organized into 19 categories. A process is a mental operation hypothesized to occur during a trial, with an identifiable onset, an eliciting condition and a measurable signature; the process selection criteria say what qualifies and what does not. Each process has a definition, references, and links to the tasks that engage it. 152 of the 172 processes are engaged by at least one task in the Catalog; the rest are kept because the Catalog may grow a task for them.

Categories group processes by research tradition for browsing. They are organizational labels, not ontological commitments: a process belongs to the category whose scope best describes where it is studied, and categories imply no inheritance. Every process has one primary category, where its entry is filed, and may be cross-listed under others as a secondary member; 0 processes are cross-listed at present, and 0 memberships are marked review. The process category rules say how categories are assigned.

A review mark means the assignment is a judgement call the curator has flagged for a second opinion. On the category an entry is filed under it means “not sure this is the right home”; on a cross-listing it means “not sure this belongs here at all”. The note names the alternative or the doubt. Comments go to the issue tracker.
