Normal and learning disabled children were presented with visual and auditory items for free and cued recall. Deficits in semantically cued recall for children with one impaired modality originated at presentation time, perhaps because of separate pathways linking the auditory and visual modalities to the semantic system.

The extent to which an orienting activity exerts control over the encoding process was studied. Two experiments were reported in which associative meaningfulness was varied under conditions of semantic and nonsemantic processing. Both experiments showed effects of meaningfulness following both semantic and nonsemantic tasks. (Author/MH)

A multirate mathematical model is presented to support the hypothesis that different types of information are lost from a memory trace at different rates. The model is validated by two experiments assessing the retention of pictures and of sentences at three different delays by cued recall. (Author/CP)
