Notes
- response_option_index = 0 means the subject chose none of the options (e.g., a “no-go” response in a Go/No-go task).
- response_option_index can be directly compared to expected_response_option_index.
- response_option_index refers to an entry in the Option table.
- Not to be confused with response_index: response_option_index indexes into the set of options (WHICH option was chosen), whereas response_index is the ordinal position of the response itself within the subject's study participation (see the response_index field; cf. also response_element_index in the Input table for the pieces of one response).
