Notes
- When expected_response_option_index = 0, it means that the subject should not respond at all.
- Sometimes stimuli serve both as stimuli and as response options as subjects have to click on a particular stimuli to give their response (e.g., spatial span, odd one out). It is convenient in those cases to use stimulus_position_index to order/index the options (i.e., option_index == stimulus_position_index) and consequently also the responses.
