Navon (1977) presented participants with big letters made up of smaller letters. He had some participants identify the large letter, while other participants had to identify the smaller letters.
 
  Finally, on some trials, the large and small letters conflicted (e.g., a large H made of small S's) while on other trials, the large and small letters were consistent (a large H made up of small H's). What did he find?
   a) Participants were faster at identifying small letters than they were at identifying large letters.
   b) Conflict between the large and small letters didn't influence the ability to identify the small letter.
   c) Conflict between the large and small letters made it more difficult to identify the small letter.
   d) Conflict between the large and small letters made it easier to identify the large letter.
