fixationGrid
elements
A grid of concentric circles and diagonal lines intended to stabilize fixation. As used in Tyler, C.W. et al. (2005). Extended Concepts of Occipital Retinotopy.
▸ Object ends on its own?
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.
Input properties
Adjustable properties
You can vary or allow the subject to adjust the following input properties of an object of this type in real time when it's running. If you need to make other properties adjustable, you can edit the element type code—see Element Type Programming Manual.

size
Default: fill screen
Square size of the grid (deg). This determines how many circles you see and the length of the diagonal lines. <cd>inf<cd> = fill screen (at any position, not necessarily centered on screen).
innerRadius
Default: 1 deg
Radius of innermost circle (deg)
radiusIncrement
Default: 6 deg
Distance between concentric outer circles (deg).
lineWidth
Default: 0.05 deg
Line width (deg).
color
Default: 50% grey
A 1×3 RGB vector with numbers between 0–1.

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