Word Relatedness 2 Abstract Participants were presented with a series of a pair of letter strings, which were either related, not related, or were a word paired with a nonword. They were asked to report whether the second string of letters was a word or a nonword. The reaction time to correctly identify the second letter string was quicker if the two words were semantically associated with each other. This supports the hypothesis that response time to the second word should be faster if the first word is associated with it, since mental lexicon is organized by semantic meaning.

Word Relatedness 3 Effect of Word Relatedness on Reaction Time to Word Identification Most people are familiar with the concept of a dictionary; a collection of words arranged alphabetically, containing information about each word’s meaning and pronunciation, among other information. Human minds have a mechanism that is similar to a dictionary, called a lexicon, which stores information about words and other language components. This “mental dictionary” would not be very useful to us if it were arranged alphabetically. When we need to know which word to say, the appropriate word does not depend on what its first letters are, but rather on the meaning of the word and its relationship to other words. Words in our lexicons that are related to each other are close together, and create semantic networks that increase the efficiency of our lexicons. The increased efficiency is due to neural activity in the lexicon called spreading activation, defined by Goldstein as “activity that spreads out along any link in a network that is connected to an activated node” (2005). In the case of the lexicon, the nodes are words, and when a word is activated neural activity spreads to the words around it that are semantically related to it. Padraig G. O’Seaghdha demonstrated this effect in his experiment concerning
