Using a network of comparisons, B. Hayes-Roth and F. Hayes-Roth found that subjects performed better on adjacent than on nonadjacent comparisons. Results suggested that such networks are processed in a manner fundamentally different from simple linear arrays. Here subjects were required to learn a similar knowledge structure. These results…

The nature of the target designation process--which involves forming interassociated mental structures to allow retrieval of individual items of information--was studied. It was shown that visual imagery instructions improved target identification as well as word recognition but did not appear to affect the representational format. (Author/MH)

Reber found that subjects given neutral instructions to memorize letter strings from a synthetic language learned more about the underlying grammar than those instructed to try discovering the rules for letter order. Two experiments explored the relationship between implicit and explicit processes in the acquisition of complex knowledge.…

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)
