Version: v26.0721 Namespace: https://behaverse.org/schemas/trial

Tidy tables describing trial-level behavioral data for cognitive tests and questionnaires, derived from raw events.

Trial-level data is organised as 9 tidy tables (190 fields total), joined by _id foreign keys. Open a table to browse its fields.

Table	Fields	Description
Response	79	Main table where each row describes a response in a trial.
Stimulus	19	Describes each of the stimuli that were shown during a trial.
Option	18	Describes each option that a subject could choose from in a trial.
Input	15	A detailed log of all inputs and clicks recorded during the trial.
StimulusComponent	13	Stimuli can comprise multiple components. This table describes each component of a stimulus.
OptionComponent	14	Options can comprise multiple components. This table describes each component of an option.
Instrument	7	Describes the instrument used for data acquisition.
Subtrial	19	Per-stage detail for trials composed of successive, dependent stages, each with its own stimulus → response → outcome cycle (e.g., the two-step task). The trial row in Response remains THE unit and carries the trial-level (aggregate or final) response and evaluation; each Subtrial row is a miniature trial anatomy for one stage.
TaskParameter	6	Per-trial ground-truth GENERATIVE task parameters (latent task state, not behavior), in long format: one row per parameter (and grid cell) per trial — e.g., a bandit's true reward probabilities per (state, action), a slot machine's true means. Serves simulation, parameter recovery, and engine calibration.
