![]() ![]() This supersedes either choices or scaleDescription. This is intended to bias people away from thinking in terms of numbers, and focus more on the visual bar when making their rating. If this is checked, a line with no tick marks will be presented using the ‘glow’ marker, and will return a rating from 0.00 to 1.00 (quasi-continuous). What information to save, how to lay it out and when to save it. ![]() If checked, when the subject makes a rating the routine will be ended. scaleDescription stringīrief instructions, reminding the subject how to interpret the numerical scale, default = “1 = not at all … extremely = 7” forceEndRoutine bool If there are any commas, the string will be interpreted as a list of words or phrases (possibly including spaces) that are separated by commas. Spaces are assumed to separate the words. (Probably more than 6 or so will not look so great on the screen.) Instead of a numeric scale, you can present the subject with words or phrases to choose from. See Defining the onset/duration of components for details. The duration for which the stimulus is presented. The time that the stimulus should first appear. The name should contain only letters, numbers and underscores (no punctuation marks or spaces). ‘scale description’: used for numeric choices, e.g., 1 to 7 ratingĬomplete control over the display options is available as an advanced setting, ‘customize_everything’.Įverything in a PsychoPy ® experiment needs a unique name. ‘category choices’: choose among verbal labels (categories, e.g., “True, False” or “Yes, No, Not sure”) ‘visual analog scale’: the subject uses the mouse to position a marker on an unmarked line Three common usage styles are enabled on the first settings page: A routine from a personality questionnaire could have text plus a rating scale. Both the response and time taken to make it are returned.Ī given routine might involve an image (patch component), along with a rating scale to collect the response. By combining a Slider, Text/TextBox and Button components, a Slider should be able to perform all the same tasks as a RatingScale Component.Ī rating scale is used to collect a numeric rating or a choice from a few alternatives, via the mouse, the keyboard, or both. Any help for alternative methods would be greatly appreciated.The Rating Scale Component is in the process of deprecation, if possible we recommend using the newer Slider component instead. My thoughts are that I can accomplish this by editing the underlying code for PsychoPy, though I feel this is a little out of my comfort zone. The desired outcome is to have the marker move continuously as the left or right key is pressed. The marker only moves 1-point (between 0 and 100) every time the user presses and releases the key. This code actually works pretty well to get started, but I have a problem with the way the keyboard input works. ShowAccept=False, noMouse=True, maxTime = 5) MarkerStart='50', marker='circle', textSize=.5, showValue=False, Scale = visual.RatingScale(win, low=0, high=100, size=2, tickMarks=, In working to code something similar in PsychoPy, I have created the following test code: from psychopy import visual, core The participant has five-seconds to move the marker to the desired location before the experimental protocol moves on to the next stimuli. I have a script in Matlab (psychtoolbox) in which I have coded a visual analog scale, anchored at 0 and 100, on which participants move a marker by holding down the left and right arrow-keys. ![]()
