Pictures are often used by cognitive psychologists to investigate the development of cognitive functions. Different attributes of the picture, such as object or picture familiarity, word frequency, and age of acquisition, are known to correlate with naming latency and to affect memory, particularly retrieval processes. But without the use of age-appropriate stimuli it is difficult to determine whether age-related differences are due to immature memory systems or to the absence of particular items in the lexical or semantic networks of children. The purpose of this study was to obtain a normative database for pictorial material that will be useful for future studies with both young children and adults. Thirty adults and 30 children, ages 5 and 6, were asked in several sessions to name 400 individually-presented pictures, consisting of line drawings of common objects. Subjects were also asked about the familiarity and visual complexity of the picture. Among the findings were that young children are different from adults in both the name most frequently assigned and in the number of alternative names provided. The alternative names given by the children were either coordinate names or names of objects that are visually similar to the picture. In addition, the failure (to name) rate was higher among young children than adults. (Two appendices contain statistical data and pictures used in the study. Contains 27 references.) (EV)
