This reference work contains free association norms for over 2000 words in the English language, collected from groups of 40-50 British English speakers between the ages of 17 and 45. These norms should be of use to researchers and students in many fields of psychology, especially the study of language and memory, where the degree of association between pairs of words is often an important experimental variable. The main part of the book contains an alphabetical list of all associative responses and their frequency for each of the 2464 stimulus words. In addition, there is an index of stimulus words organized according to semantic category to aid selection of experimental materials. Full methodological details of the collection and compilation of the data are also provided in the introduction.
