Several measures of sensitivity (unbiased retention) and response bias are described and evaluated in terms of their applicability to the probe-type serial memory task. Suggestions are made regarding the major factors that should be considered when selecting an index for one's data. (Author/GO)

The effects of different levels of rehearsal quality on serial recall, over and above simple labeling, were studied in a sample of 104 kindergartners. Subjects were randomly assigned to four experimental conditions. In one condition the subject and experimenter rehearsed together; in a second condition only the experimenter rehearsed; in the third…

The relationships among the perception, representation, and construction of series are examined within a model of the acquisition of seriation abilities. The model is then related to two experiments with three-, four- and five-year-olds. The key feature of the model is the delineation of parallels among developmental changes in three arenas:…

This paper describes a series of studies which examine the early development of recall. Subjects were children about 2 1/2 and 5 years of age. Recall was tested on nine-item lists which were either composed of three objects from each of three conceptual categories or nine objects from nine different conceptual categories. Age differences were…

In a multiple baseline design, a teenager with a mental age of four years was taught two abstractions. One was the oddity principle (selecting the one object in a group which differs from the rest). The other was seriation (aligning objects along a continuum of size, and inserting new objects into their proper places in the alignments). These…
