A standardized set of 260 pictures for Turkish: norms of name and image agreement, age of acquisition, visual complexity, and conceptual familiarity

In the present study, normative data are presented for the 260 colour picture set of the original Snodgrass and Vanderwart (1980) cohort in Turkish for the first time. Norms are reported for name and image agreement, age of acquisition (AoA), visual complexity and conceptual familiarity together with written word frequency, number of letters and syllables. We collected data from 277 native Turkish adults in a variety of tasks. Results indicate that whilst several measures display language-specific variation, we also report language independent, i.e. universal, measures that show a systematic relationship across several languages. The implication of the reported measures in the domain of psycholinguistic research in Turkish and wider cross-linguistic comparisons are discussed.
