Impact of semantic or phonemic cues in picture-naming tasks on the calculation of the objective age-of-acquisition norms: A cross-linguistic study.

In picture-naming tasks, participants name a picture as quickly as possible. In several studies, when the participant did not provide the picture name in the first seconds after object presentation, the examiner provided phonemic or semantic cues. Under these conditions, word retrieval should be easier, thus lowering the age of acquisition (AoA). The goal of the present study was to collect objective norms of AoA in French without any kind of cue. The results were then compared with other European databases that relied on picture-naming tasks conducted with phonemic or semantic cues. Globally, the data of all the databases are significantly correlated. However, the AoA measures in these databases are always lower than in our study, except in Alvarez and Cuetos (2007), who did not provide any assistance to the participant. Therefore, giving phonemic and/or semantic cues lowers the AoA values, indicating that the values from different databases in this domain should be taken with caution.
