4) To test the theory that the deeper the level at which words are processed the better their recall, a researcher asked a group of students to learn a list of highly imaginable words. They were asked to look at the words and count how many vowels were in each word on one occasion. They were then asked to recall the words from the list. Later, they were all presented with the same words but asked to make a picture of what the word represented in their mind. Again, they were asked to recall the words from the list.
