Task mapping

Every correspondence between the tasks in the Catalog and the paradigm classes of CogPO, the Cognitive Paradigm Ontology, in both directions, the counterpart of the Atlas task mapping page: a summary of each direction by match type, then the full row tables. The CogPO mapping method page explains what the match types mean and how each row was decided, and The Catalog vs CogPO says what the correspondence adds up to.

The source of record is data/mappings/, not this page. A CogPO class name links to its page on the CogPO wiki, the only place the class can be read online; the wiki is reachable over plain http only, because its certificate is invalid. The two Oddball subclasses have no wiki page and are not linked.

Catalog to CogPO

Tasks in the Catalog by the match type of their primary CogPO class:

Match type	Tasks	Share
exact	24	22%
close	22	21%
related	26	24%
none	35	33%

One row per task in the Catalog, recording its primary CogPO class. A related row names a broad class the task falls under rather than a counterpart; task pages link to CogPO only for exact and close rows.

CogPO to Catalog, classes with a counterpart

Of the 86 CogPO paradigm classes, 50 have a counterpart in the Catalog (27 exact, 15 close, 8 related) and 36 have none; 5 of the matched classes resolve to a named variation rather than a task.

CogPO paradigm classes by match type:

Match type	CogPO classes	Share
exact	27	31%
close	15	17%
related	8	9%
none	36	42%

One row per CogPO class with a counterpart in the Catalog. A variation row resolves to a named variation of a Catalog task rather than to the task itself.

CogPO paradigm class	Match	Level	Catalog task	Note
Anti-Saccades Paradigm	exact	task	Anti-Saccade Task	Same paradigm.
Auditory Oddball Paradigm	exact	variation	Oddball Task (variation: Two-Stimulus Auditory Oddball)	Auditory Oddball is an alias of the Catalog’s Oddball Task; its standard form is the two-stimulus auditory variation.

Delay Discounting Task Paradigm	exact	task	Delay Discounting Task	Same paradigm.

Deductive Reasoning Paradigm	close	task	Wason Selection Task	A class of reasoning tasks. Wason Selection is the Catalog’s deductive reasoning task; Raven’s Progressive Matrices is inductive but CogPO’s definition would admit it.
Episodic Recall Paradigm	close	task	Autobiographical Memory Task	CogPO’s class is recall from episodic memory in general, with autobiographical recall as the typical use; the Catalog’s Autobiographical Memory Task is that typical case.

Passive Viewing Paradigm	close	task	Affective Picture Viewing Task	Viewing with no response, any visual stimulus. The Catalog’s Affective Picture Viewing (alias Passive Viewing Task) is the affective case; the Face Processing localizer is another.

Drawing Paradigm	related	task	Mirror Tracing Task	Drawing with a pen or stylus. Mirror Tracing is a drawing task with a perceptual-motor manipulation; plain drawing is a motor act the Catalog does not list.
Encoding Paradigm	related	task	Free Recall Task	An encoding phase, not a task: every Catalog memory task (Free Recall, Old/New Recognition, Paired Associates, Self-Referential Encoding) contains one. CogPO codes the phase because BrainMap contrasts isolate it.
Orthographic Discrimination Paradigm	related	task	Lexical Decision Task	Judgements on letter case, spelling or alphabetic order. The Catalog’s word tasks are lexical (Lexical Decision) or phonological (Phonological Awareness); none is orthographic.
Passive Listening Paradigm	related	task	Mismatch Negativity Task	Listening with no response. The Catalog’s Mismatch Negativity Task is a passive auditory paradigm but with an oddball structure; there is no plain passive-listening task.
Reward Task Paradigm	related	task	Monetary Incentive Delay Task	Any task with performance-contingent reward: a class, not a paradigm. The Catalog’s reward tasks (Monetary Incentive Delay, Iowa Gambling, Multi-Armed Bandit, Probabilistic Selection, Reversal Learning, Two-Stage Decision, Effort-Based Decision-Making, Social Incentive Delay) all fall in it.
Tone Monitor/Discrimination Paradigm	related	task	Auditory Masking Task	Tone discrimination by order, timing, pitch or amplitude. Auditory Masking (tone-in-noise detection) and Mismatch Negativity use tones but are different paradigms.
Visual Distractor/Visual Attention Paradigm	related	task	Visual Search Task	CogPO’s own catch-all for visual attention. Visual Search, Change Detection, Psychomotor Vigilance, Useful Field of View and RSVP all fall in it; none is its counterpart.

CogPO to Catalog, classes with no counterpart

What the class is	CogPO classes
Paradigms the Catalog does not list	15
Broad classes with no single counterpart	3
Physiological procedures and interventions	11
Motor acts	6

The kind assigned to each unmatched class is a hand-checked judgement, not a rule: with 86 classes, every one was read against its definition. The first group is the one that matters for the Catalog, since each entry is a task it could list.

Reading the two directions together

The directions answer different questions. The Catalog-to-CogPO table asks whether CogPO has a class for a given task; the CogPO-to-Catalog table asks, for each CogPO class, whether the Catalog covers it. A CogPO class that is a broad family (Reward Task, Encoding, Visual Attention) can therefore be related to one Catalog task in the second table while eight tasks point at it as related in the first. Both statements are true: the class covers them all and is none of them.
