evaluation_label
There are several labels that can be assigned to a given response to specify what that response means in terms of evaluation within a task. The most general terms are "correct” and "error" (which are already given by the correct variable). There are however more specific sets of terms that may apply in different contexts. For example, in a signal detection task, it is common to use labels from the signal detection theory framework (i.e., “hit”, “miss”, “false alarm”, “correct rejection”). In other contexts, researchers might use terms like “omission” or “commission” errors or even things like “perseveration” error (e.g., in the Wisconsin Card Sorting Test). Note that these terms are not always well defined or exclusive. For example, a “hit” is also a “correct” response and a “false alarm” may be synonymous to “commission error”. Whenever possible use the more specific terms (i.e., always use “hit” rather than “correct” when applicable). Here are few evaluation labels that are commonly used:
