In Exp I, 328 adjectives were presented to 324 undergraduates for rating of imagery (I), ease of definition (ED), and animateness (A). The normative value of these indices was tabulated for each adjective. A correlational analysis of these measures and Ku{\v{c}}era-Francis frequency (KF) is also presented. To demonstrate the usefulness of these rating scales, Exp II requested 90 undergraduates to free recall a list of 50 adjectives after they completed an incidental learning task of rating these adjectives for I, ED, or A. Ss recalled more high I than low I adjectives and more difficult- than easy-to-define adjectives regardless of which incidental rating task they performed. Neither the degree of animateness nor the KF value of the adjectives influenced the percentage of recall.
We are interested in how directly the following adjectives are available to the senses. Many adjectives refer to properties that are directly perceived by your senses, for example, soft (fur), black (dress), bitter (taste). Many other adjectives refer to properties that are not directly observed, for example, former (inventor), effective (contract), typical (problem). We would like you to rate each adjective on the following scales:
