Naming times for the Snodgrass and Vanderwart pictures

This paper reports the results of two experiments. In the first, voice-key naming times were collected and in the second, keypress naming times were collected for 250 of the Snodgrass and Vanderwart (1980) pictures. The resulting naming times and correct naming rates were well predicted in multiple regression analyses by one or another measure of codability (name or concept agreement) and by age-of-acquisition ratings collected specifically for this study, Voice-key responses appeared to be somewhat more sensitive indicators of naming difficulty, although keypress responses did remarkably well. The Appendix presents the age-of-acquisition ratings, the trimmed vocal and keypress naming times, and the correct naming rates from the two experiments for the 250 pictures.
