Developmental differences in name agreement, familiarity, and visual complexity in response to line drawings of common objects were obtained from children and adults. Sixty-one pictures were taken from the Peabody Picture Vocabulary Test-Revised and 259 pictures were taken from the set normed for adults by Snodgrass and Vanderwart (1980). Although there were some differences between the two sets of pictures, the present results replicated the relative independence of these three measures, which was reported by Snodgrass and Vanderwart for adults. Children and adults showed substantial agreement on the names of the pictures. Although the children's ratings were lower on all measures, the differences were trivial for most pictures. We concluded that judgments of familiarity, complexity, and the names of line drawings of common objects are based primarily on information processing accomplished prior to age 7.
{"name_agreement": "The subjects were instructed to write the single best name of each picture on the corresponding line. They were told that a name could consist of more than one word (e.g., \"swimming pool\"). If the subjects could not recognize a pictured object, they were told to write \"T\" If they knew the object, but did not know its name, or momentarily could not think of the name, they were told to write \"?name.\"", "familiarity": "The subjects were instructed to circle \"very little,\" \"some,\" or \"a lot\" in response to the question, \"How much do you see or think about this thing?\"", "visual_complexity": null}
