The 1984 Dictionary of Affect in Language by Sweeney and Whisseli includes more than 4,000 words which have been rated along the bipolar affective dimensions of Evaluation and Activation. A series of three experiments was conducted to evaluate the reliability and validity of the Dictionary and to improve its reliability by the inclusion of additional ratings. Exp. I, II, and III demonstrate the reliability of the Dictionary values and provide evidence of concurrent validity. A further series of three experiments (IV, V, VI) was designed to apply the Dictionary as a tool for assessing or preselecting the affective tone of words. Success (as defined by significant effects) is associated with the use of the Dictionary in choosing words for a verbal learning experiment (IV) and its use to score freely produced self-descriptive word lists (V) and the description of famous media characters (VI).
