In this case, the mapping between number and color is constant. Some individuals have a grapheme-color form of synesthesia, where they see colors when viewing letters or numbers. For this person, the number 3 generally appears red, while the number 7 generally appears green. One way to test whether someone actually has this form of synesthesia is to have the person hunt for shapes hidden in an array of similar-looking numbers. For example, the following array contains 5s organized into a shape among 2s. What results would you expect when comparing participants with grapheme-color synesthesia against controls?

Question

a- Individuals with grapheme-color synesthesia should be considerably faster and more accurate than controls at detecting the hidden shape.
b- Control participants should be faster at completing this task but will show more errors than individuals with grapheme-color synesthesia.
c- Control participants should be unable to complete the task, while individuals with grapheme-color synesthesia will find it difficult but doable.
d- Individuals with grapheme-color synesthesia should have more difficulty than controls at doing this task.
