Trials
Trials are the main features of the scientific experiment
A trial is a single instance of a participant interacting with a task. It contains information about the participant, the task, and the interaction between the two. BDM supports multiple trial-related tables that are designed to be as flexible as possible, allowing for a wide range of cognitive tasks to be represented.
We use icon to refer to specific tables. For example the Trial table or the Stimulus table.
Trial
Main trial table where each row describes a response in a trial.
Stimulus
Describes each of the stimuli that were shown during an trial.
Option
Describes each option that a subject could choose from in a trial.
Input

StimulusComponent
Stimuli can comprise multiple components. This table describes each component of a stimulus.
OptionComponent
Options can comprise multiple components. This table describes each component of an option.
Instrument
Describes the instrument used for data acquisition.
Here is a diagram of the trial-related tables. The diagram shows the relationships between the tables and their attributes. The Trial table is the main table.
