This comparative study addresses free recall using an independent group design. Thirty children (X = nine years) and 30 adults (X = 21 years) studied 50 colour slides representing common objects in order to attempt to recall afterwards as many of them as possible in four trials held three min., one hour, 24 hours, and seven days following one single acquisition trial. One basic aim of this research is to explore whether hypermnesia, increasing retrieval across trials, emerges from a relatively early age, i. e., nine years, or if it has to go through certain developmental steps in order to function as is commonly observed in adult samples. There were three significant results. There are differences in level of recall as a function of age. Adults recall more stimuli than children across four trials. Adults not only recall more stimuli than children but their recall is incremental across trials. On the other hand, the recall of children does not decrease but stays stable across seven days. Therefore, there is a significant interaction between children and adult recall. We present evidence supporting the notion that retrieval mechanisms and hypermnesia require the development of certain cognitive skills in order to operate at a mature level.

    In the part-set cuing effect, cuing a sub set of previously studied items impairs recall of the remaining noncued items. This experiment reveals that cuing participants with previously studied emotional pictures (e.g., fear evoking pictures of people) can impair recall of pictures involving the...
