Factors affecting word retrieval were compared in a timed picture-naming paradigm, for 520 drawings of objects (stimuli is available as freeware) . In prior timed and untimed studies by Snodgrass and Vanderwart (1980) and Snodgrass and Yuditsky (1996), concerns were raised that participants could not reliably name large numbers of items in a single session. We show that reliable results are obtained in a single session for 520 items, and validate our method against previous findings for overlapping items. For these items, comparable levels of name agreement and latency are obtained, and we replicate effects of length, frequency, both objective and subjective age of acquisition and visual complexity on reaction time and name agreement measures. Our database is available for research purposes. Name agreement is unaffected by order of presentation, although there is gradual increase in reaction times across the session, requiring use of multiple random orders. Current extensions of our method include cross-linguistic, bilingual, developmental and neuropsychological studies, and comparisons of action and object naming.
