Auto Color -
The background color of the
Calibration
screen is set
automatically using an
average gray level of the current screen
content.
Target Color
- When you select
Disc
for a target shape, you can then
set the color of the calibration point using the
Available Colors
popup
window to select from a range of grayscale colors.
Background Color
- If
Auto Color
is deselected, you can select from a
set of grayscale colors for the background of the
Calibration
screen.
The default color is gray.
The background color should be similar to the color of
the stimuli used in the experiment to maintain the
same level of brightness. Changing the brightness
causes the participant's pupils to change, which can
affect the calibration.
11.6 Running a Validation
The calibration can be validated (optional) with the same participant
using a procedure similar to that used during the calibration process.
To run a validation:
1. After running a calibration, and with the same participant, click
Validate
on the
Calibration
tab.
