In this study, we report normative data by native Persian speakers for concept familiarity, age of acquisition (AoA), imageability, image agreement, name agreement, and visual complexity, as well as values for word frequency, word length, and naming latency for 200 of the colored Snodgrass and Vanderwart (Journal of Experimental Psy- chology: Human Learning and Memory 6:174-215, 1980) pictures created by Rossion and Pourtois (Perception 33:217-236, 2004). Using multiple regression analysis, we found independent effects of name agreement, image agree- ment, word frequency, and AoA on picture naming by native Persian speakers from Iran. We concluded that the psycholinguistic properties identified in studies of picture naming in many other languages also predict timed picture naming in Persian. Normativedatafor theratings and picture-naming latencies for the 200 Persian object nouns are provided as an Excel file in the Supplemental materials.
The effects of psycholinguistic variables such as name agreement, rated image agreement, rated familiarity, rated age of acquisition (AoA), rated imageability, rated visual complexity, word frequency, and word length on picture-naming latencies are well documented in different languages (Alario et al., 2004; Cuetos, Ellis, & Alvarez, 1999; ...)
