Solution-word imagery appears to affect difficulty of anagram solving. To assist research in this area, we present imagery, concreteness, age-of-acquisition, familiarity, and meaningfulness values for 205 five-letter words known to form single-solution anagrams. None of the words have repeated letters. Intergroup reliabilities were satisfactory on all attributes. Significant correlations were found with previous word lists and the intercorrelations between dimensions matched previous findings.Recent studies have found that high-solution word imagery facilitates anagram solving (Dewing & Hetherington, 1974;Jablonski & Mueller, 1972; Stratton, Jacobus, & Leonard, 1975). However, word imagery is correlated with other potentially important attributes, notably concreteness, meaningfulness, familiarity, and age-of-acquisition (Paivio, Yuille, & Madigan, 1968; Stratton, Jacobus, & Brinley, 1975). Analysis of the effects of such word attributes on anagram solving has been hampered by the lack of appropriate norms for a sufficiently extensive set of suitable words. The Paivio et a1. list of imagery, concreteness, meaningfulness, and frequency values is not ideal for anagram research because of the variation in word lengths and the presence of letter repetition within words on the list. Stratton, Jacobus, and Brinley (I975) have provided a partial remedy with their list of imagery, familiarity, meaningfulness, and age-ofacquisition values for 543 words of which 72 are fiveletter and 471 are six-letter. The list is clearly useful for six-letter words, but less so for five-letter words. The present study gathered imagery, concreteness, age-of-acquisition, familiarity, and meaningfulness values on 205 words taken from Olson and Schwartz's (I967) list of single-solution five-letter anagrams, and so provides a further stock of rated words to supplement those already available. The list may be useful in studies of word perception, learning, and memory, as well as in anagram research.
METHOD
SubjectsThe subjects were first-year student volunteers attending Aberdeen University. Imagery ratings were given by 50 subjects. Concreteness, age-of-acquisition, and familiarity ratings were given by three separate groups of 40 subjects each. The rating Requests for reprints should be sent to K. J. Gilhooly, Department of Psychology, University of Aberdeen, Aberdeen AB9 2UB, Scotland. 12 groups were equally divided between males and females. A total of 257 subjects were involved in the meaningfulness measuring procedure and each word's score was based on data from between 20 to 30 subjects.
WordsThe 205 five-letter words were selected from the Olson and Schwartz (1967) list of single-solution words. The words selected were not plurals, were not proper names, could be used as nouns, and were judged to be reasonably familiar. None of the words selected had repeated letters.
ProcedureFor the imagery, age-of-acquisition, concreteness, and familiarity ratings, the following procedure was used.The words were printed in random order in columns ...
