gaussian
element objects
A Gaussian blob.
▸ Object ends on its own?
("Ends on its own" means ends automatically at that point. If an element can end on its own, you don't need to set end conditions for it in property end, unless you want it to maybe end earlier.)
No—runs until a condition you set in property end.

sigma
Default: 0.75 deg
Standard deviation of the Gaussian (deg). You can also use a vector <cd>[s_x s_y]<cd> for an asymmetric Gaussian.
size
Default: 6 × sigma
Sets a finite display area for the Gaussian. Generally this just needs to be big enough that the Gaussian doesn't look clipped at its edges. Typically you can leave it at default = 6 × whatever sigma is above. If you set it, it can be a number that is side length for a square, or a vector [width height] for a rectangle (deg).
color
Default: white
A 1×3 RGB vector with numbers between 0–1.
Adjustable properties
You can vary or allow the subject to adjust the following properties of an object of this type when it's running. If you need to make other properties adjustable, you can edit the element type code—see Element Type Programming Manual.

PsychBench uses record properties to record information during experiments. You can't set record properties but you can see them in experiment results using input property report.
