This graph shows that the response rate for a simple cell with a 90-degree orientation
A)will always be greater for the 90-degree orientation than for any other orientation,regardless of contrast.
B)could be greater for the 80-degree orientation than for the 90-degree orientation if the 80-de- gree orientation bar had a higher contrast.
C)could never be the same for bars of different orientations.

Question

Quizplus · Accepted Answer

The graph shows that the response rate for the 80-degree orientation bar can be higher than that for the 90-degree orientation bar if the 80-degree orientation bar has a higher contrast. Therefore, option B is the correct answer. Option A is incorrect because the response rate for other orientations can also be high depending on the contrast level. Option C is incorrect because the graph shows that the response rates could be the same for bars of different orientations, depending on their contrast levels.
