Pictures are often used in studies on memory, perception, and language; normative data are thus needed for such visual stimuli. In the present study, we aimed to obtain normative data for a set of 272 black-and-white pictures from middle-aged and elderly Persian speakers. A total of 206 volunteers were divided into two groups: a middle-aged (40–59 years old) group and an elderly (60 years old and over) group. The groups had similar characteristics in terms of education. Norms for every picture were developed to provide measures of name agreement, image agreement, conceptual familiarity, age of acquisition, and visual complexity. The results revealed that all of these measures vary with age, except for conceptual familiarity.
