The idea was explored that different subjects may use qualitatively different encoding strategies with the same information presented within the same experimental situation. The premise was also studied that different strategies may be evoked by subtle differences in advance instructions or in the context of the task. (Author/MH)

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)

These experiments focus upon two assumptions of the levels of processing formulation: that context provides exclusive control over the qualitative nature of encoding, and that amount recalled is determined both by cue-trace compatibility and by depth. The results cast doubt upon the validity of each assumption. (Author/MH)
