Text Component
This component can be used to present text to the participant, either instructions or stimuli.
- name
: string- Everything in a PsychoPy experiment needs a unique name. The name should contain only letters, numbers and underscores (no punctuation marks or spaces).
- start :
- The time that the stimulus should first appear. See Defining the onset/duration of components for details.
- stop :
- The duration for which the stimulus is presented. See Defining the onset/duration of components for details.
- color :
- See Color spaces
- color space
: rgb, dkl or lms- See Color spaces
- ori
: degrees- The orientation of the stimulus in degrees.
- pos
: [X,Y]- The position of the centre of the stimulus, in the units specified by the stimulus or window
- height
: integer or float- The height of the characters in the given units of the stimulus/window. Note that nearly all actual letters will occupy a smaller space than this, depending on font, character, presence of accents etc. The width of the letters is determined by the aspect ratio of the font.
- units
: deg, cm, pix, norm, or inherit from window- See Units for the window and stimuli
- opacity :
- Vary the transparency, from 0.0 = invisible to 1.0 = opaque
- flip :
- Whether to mirror-reverse the text: ‘horiz’ for left-right mirroring, ‘vert’ for up-down mirroring.
The flip can be set dynamically on a per-frame basis by using a variable, e.g., $mirror, as defined in a code component or conditions file and set to either ‘horiz’ or ‘vert’.
