Semantic differential (SD) factor scores on the Evaluation, Activity, and Potency dimensions are presented for 1,000 most frequently used English words. Also given are the standard errors of the factor scores, the results of several reliability studies, and a listing (for all words) of 3 types of derived scores: polarizations, n Affiliation contents, n Achievement contents. Test-ing procedures and statistics on the sample of raters are detailed. Some uses of the dictionary are suggested, and an example of its use in a study of motivation is presented including empirical results. Conditions favoring further cumulation of SD data are discussed. THE semantic differential (SD) has proven to be an accurate instrument for recording affective associations of stim-uli, particularly to the extent that such as-sociations are culturally or subculturally denned so that measurements may be aver-aged over groups of individuals (Norman, 1959). In a wide variety of studies, includ-ing many involving cross-cultural samples of raters, it has been demonstrated that affective judgments on bipolar adjective scales reliably resolve into three major dimensions or factors which Osgood has named Evaluation, Activity, and Potency 'This paper is part of a doctoral dissertation submitted to the
Ratings on bipolar adjective scales were obtained from a dictionary of semantic profiles for emitted words.
