In three experiments, subjects learned two lists under incidental conditions and were then given either a part-word or a word (extralist associate) cue. Each cue was related to one word in each list. Half the subjects were given production instructions (an indirect memory test), and half were given cued recall instructions (a direct memory test). When the interval between List 2 and the test was shortened, recency effects were found for part-word cues for both cued recall and production instructions. Little or no recency effects were found with word cues. These results are incompatible with a simple distinction between the types of memory trace or information that are tapped by direct as opposed to indirect memory tasks. Possible causes for the recency effect and for the difference between word and part-word cues are discussed.
321According to Richardson-Klavehn and Bjork (1988), the tasks that Humphreys, Bain, and Pike (1989) refer to as cued recall and production can be classified as direct and indirect memory tasks, respectively. A direct memory task is defined by the instructions to subjects to utilize information about a particular episode. In the case of cued recall, subjects study a list of words and are then asked to retrieve those words with the aid of cues. The instructions specify the episode in which the target words have occurred and state the relationship between cues and targets. More specifically, in the case of part-word cues, the subjects are provided with cues that are partial representations of the target words (i.e., stems, endings, or fragments). They are told that each cue is part of a word from the target list, and they are asked to add letters to complete each cue with a word from the specified episode. Ifextralist word cues are provided (e.g., taxonomic category labels or preexisting associates of the target words), the subjects are told that each cue is related to a word from the target episode and should help them to recall the words from the list.In contrast, an indirect memory task is defined by instructions that do not make any reference to a particular episode, but refer only to the task at hand. This classification includes the production task of interest in this paper. The term production is used by Humphreys et al. (1989) to refer to an indirect retrieval task. This type of task requires subjects, after studying a list of words, to produceThe first two experiments constituted part of the first author's Master's thesis at the University of Queensland.
