Children aged approximately 8.5-9.5 years were shown either names (NP), or pictures (PP), of objects, for each of which they located the corresponding likenesses among an array of alternatives. Written recall and identification accuracy were assessed at 5 hr and 3 days after presentation. As predicted. NP produced sgnificantly superior recall to PP. The rate of identification for recalled items among Ss in PP was significantly higher than that for NP. This result was interpreted as supporting the view that the superiority of NP in recall derives from the fact that Ss may rely upon retrieval from eiter name or image of each item whereas those in PP must depend upon image alone. This interpretation was extended to take two unexpected findings into account : (i) the superior overall identification accuracy engendered by PP, particularly at the longer time interval; (ii) the relatively weak relationship between identification accuracy and recall scores among matching Ss.
