When subjects are tested on ordered information, performance is better on inferences than on information actually presented during training. Humphreys suggested that superiority on inferences derives from differential frequency. This experiment refutes that position, demonstrating that superiority on inferences is observed even when frequency is…

In two experiments using the Brown-Peterson memory paradigm, instructions to guess had small effects on recall, but sizeable effects on incidence of prior list intrustion. However, results indicate that proactive interference is primarily the result of inability to generate correct items, rather than confusion between present and previous items.…

When subjects utter a series of redundant sounds while memorizing word lists, performance is impaired and phonemic similarity effect is reduced. Experiments explored the influence of articulatory suppression on free recall; neither showed interaction between suppression and serial position. Recency effect may not reflect short-term phonemic store.…

One hundred forty-four subjects received 4 Brown-Peterson trials with recall triads from a common encoding category. Items on three trials were from a common subset, while on the fourth, the subset was shifted or not, and a cue was presented or not. The cue influenced response generation, a shift improved recall.

A description of a series of six experiments dealing with human memory processes. They examined the types of codes generated in maintenance rehearsal and the effects of rehearsal time at various single levels of encoding. Data confirmed earlier findings and led to conclusions regarding repetition, encoding and levels of processing. (AMH)
