Ratings of concreteness and picturability and production data for meaningfulness of 310 words were gathered from 207 6th-grade children and 265 college adults. Adults also provided ratings of imagery value. Correlations among the various stimulus attributes indicated that for adults, imagery, concreteness, and picturability were overlapping attributes. For children, however, the attributes of concreteness and picturability did not overlap as much.
{"childInstructions": "The words were typed 20 to a page, with a 7-point numerical scale next to each word. To obtain reliability on the ratings, 30 words were rated twice.", "adultInstructions": "The instructions to obtain indices of meaningfulness informed the subjects that they were to rate how concrete or abstract they thought each word was."}
