Direction keys (left, right) will move the marker in the smallest available increment (e.g., 1/10th of a tick-mark if precision = 10). The subject can use the mouse or keys to respond. The experimenter has to draw the item to be rated, and handle `escape` to break or quit, if desired. A RatingScale instance has no idea what else is on the screen. #PSYCHOPY SCALE RESET FULL#The Builder RatingScale component gives a restricted set of options, but also allows full control over a RatingScale via the 'customize_everything' field. Multiple scales can be displayed at the same time, and continuous real-time ratings can be obtained from the history. The appearance and function of elements can be customized by the experimenter it is not possible to orient a rating scale to be vertical. #PSYCHOPY SCALE RESET HOW TO#There are five main elements of a rating scale: the `scale` (text above the line intended to be a reminder of how to use the scale), the `line` (with tick marks), the `marker` (a moveable visual indicator on the line), the `labels` (text below the line that label specific points), and the `accept` button. You can call the ``getRating()`` method anytime to get a rating, ``getRT()`` to get the decision time, or ``getHistory()`` to obtain the entire set of (rating, RT) pairs. When the subject accepts a selection, ``.noResponse`` goes ``False`` (i.e., there is a response). ``draw()`` displays the rating scale, handles the subject's mouse or key responses, and updates the display. A RatingScale instance is a re-usable visual object having a ``draw()`` method, with customizable appearance and response options.
