An event class for presenting image-based stimuli
Stimuli
PsychoPy
Name of this Component (alphanumeric or _, no spaces)
How do you want to define your start point?
Options: - time (s) - frame N - condition
How do you want to define your end point?
Options: - duration (s) - duration (frames) - time (s) - frame N - condition
When does the Component start?
When does the Component end? (blank is endless)
(Optional) expected start (s), purely for representing in the timeline
(Optional) expected duration (s), purely for representing in the timeline
The image to be displayed - ‘sin’,’sqr’… or a filename (including path)
Store the onset/offset times in the data file (as well as in the log file).
Synchronize times with screen refresh (good for visual stimuli and responses based on them)
Disable this Component
Name of validator Component/Routine to use to check the timing of this stimulus.
Options are generated live, so will vary according to your setup.
Units of dimensions for this stimulus
Options: - from exp settings - deg - cm - pix - norm - height - degFlatPos - degFlat
Position of this stimulus (e.g. [1,2] )
Size of this stimulus (either a single value or x,y pair, e.g. 2.5, [1,2]
Orientation of this stimulus (in deg)
Options: - -360 - 360
Foreground color of this stimulus (e.g. $[1,1,0], red )
In what format (color space) have you specified the colors? (rgb, dkl, lms, hsv)
Options: - rgb - dkl - lms - hsv
Fill color of this stimulus (e.g. $[1,1,0], red )
Border color of this stimulus (e.g. $[1,1,0], red )
Opacity of the stimulus (1=opaque, 0=fully transparent, 0.5=translucent). Leave blank for each color to have its own opacity (recommended if any color is None).
Contrast of the stimulus (1.0=unchanged contrast, 0.5=decrease contrast, 0.0=uniform/no contrast, -0.5=slightly inverted, -1.0=totally inverted)
An image to define the alpha mask (ie shape)- gauss, circle… or a filename (including path)
Spatial frequency of image repeats across the patch, e.g. 4 or [2,3]
Spatial positioning of the image on the patch (in range 0-1.0)
Resolution of the texture for standard ones such as sin, sqr etc. For most cases a value of 256 pixels will suffice
Options: - 32 - 64 - 128 - 256 - 512
How should the image be interpolated if/when rescaled
Options: - linear - nearest
