- The Multisyllabic Lexical Neighborhood Test (MLNT) and Lexical Neighborhood Test (LNT) are two open-set word recognition tests. The experimenter gives a list of 24 words and the participants are expected to repeat the word after each presentation. The MLNT consists of two parallel lists. The LNT and MLNT are based on the lexical characteristics of word frequency and neighborhood density, and include words found in the vocabularies of children age three to five.
