If a participant indicated a tip of the tongue state, they were asked to provide any information about the target word they could recall. Brown and McNeill found that participants could identify the first letter of the target word, the number of syllables of the target word, words of similar sound, words of similar meaning, syllabic pattern, and the serial position of some letters in the target word better than would be expected by chance. Their findings demonstrated the legitimacy of the feeling of knowing experienced in a tip of the tongue state. This study was the foundation for subsequent research about tip of the tongue phenomenon.
