General on LabBench, Version 6.0

Questionnaire

Mon, 01 Jan 0001 00:00:00 +0000

Questionnaires makes it possible to collect input during an experimental session. Conceptually, a questionnaire is a sequence of predefined questions that can be presented either to the operator or both the participant and operator, depending on the purpose of the questionnaire.

While questionnaires naturally support classical psychometric instruments (e.g., standardised scales and surveys), their role in LabBench extends beyond this.

In addition to their role as Questionnaires, they can also function as a general-purpose interface for structured data entry, enabling:

Sequential

Mon, 01 Jan 0001 00:00:00 +0000

The sequential procedure enables state machines to implement experimental procedures. Unlike most other procedures, it has no base functionality that can be configured in the LabBench Language; instead, its functionality must be implemented by a Python script that is called from its procedure events and state events.

The purpose of the sequential procedure is to allow you to define procedures for which there is no ready-made LabBench procedure. Consequently, it is fundamentally different from all other LabBench procedures: whereas other LabBench procedures allow you to extend their functionality with Python code, the functionality of a sequential procedure must be implemented in Python.

Stimulation Sequence

Mon, 01 Jan 0001 00:00:00 +0000

The <stimulation-sequence> procedure generates stimulus sequences for evoked potentials, behavioural tasks, or similar procedures. Construct the sequence by creating a stimulus pattern to control timing and a stimulus set to define which stimuli are delivered.

The stimulation pattern <stimulation-pattern>is constructed from a composition of sequences, which can be deterministic or random. However, to use this procedure, the stimulation pattern (number of stimuli and randomisation) is generated when the procedure starts. Consequently, it is not possible to change the stimulation pattern while the procedure is running, so it cannot depend on participant performance during the procedure. Use the <sequential> procedure if the stimulation pattern depends on the participant, as that procedure is more versatile but also more complex to implement than this stimulation sequence procedure.
