3. The task inclusion test

Each task has a three-part inclusion_test that defines the boundary of the task:

3.1 Structure

{
 "procedure": "What the participant does - the observable sequence of events",
 "manipulation": "What the experimenter varies - the independent variables",
 "measurement": "What is recorded - the dependent variables and signals"
}

3.2 How to use the inclusion test

A specific experiment is an instance of a given task if and only if:

1. Its procedure matches the procedure field (the participant performs the described sequence of actions)

2. It manipulates at least one variable from the manipulation field

3. It records at least one measure from the measurement field

The procedure field is the most important. Two experiments with different manipulations or measurements but the same procedure are instances of the same task. Two experiments with different procedures are different tasks, even if they target the same cognitive construct.
