The paradigm registry: default event sequences and required fields

Each event is a list with type (fixation | text | mask | blank | region_by_region | response | question | feedback), content (a literal or a {field} reference), an optional trigger (an integer EEG code or the token "condition"/"item"), onset_locked, response keys/timeout_ms, and an optional blocks restricting the event to named blocks.

Usage

PARADIGMS

Format

A named list with one entry per paradigm (factorial, lexical_decision, priming, categorisation, self_paced_reading), each holding stimulus_fields, a counterbalance recipe and an events list.

Value

A plain named list (class "list"; no package-specific class) of built-in paradigm specifications. Each element contains stimulus_fields, a character vector naming required item-table fields; counterbalance, a character scalar naming the counterbalancing recipe; and events, an ordered list of event-specification lists. The selected entry supplies the default trial sequence, required item fields, and counterbalancing rule inherited by a design that names that paradigm.
